what should be used to clean lcd monitors made in china
Remember when your LCD or OLED display had that brand-new, fresh-out-of-the-box shine, feel and look? You are in the right place if your display is now due for deep cleaning.
Things to consider before cleaning or handling an electronic displayAvoid static by grounding your body and following proper ESD-safe handling techniques.
A microfiber cloth and distilled water is recommended for cleaning the display glass. Use Qtips and Isopropyl alcohol for cleaning the printed circuit board.
Although distilled water is recommended for wiping the display glass, you can use a cleanser developed explicitly for cleaning displays. However, do not spray it directly onto the display. Spray a tiny amount of the cleaner onto a microfiber cloth first to avoid getting any cleaning solution inside the display.Never spray any liquids directly onto the display.A spray is too hard to control and confine. The fluids can seep into the other display layers or surrounding components and cause irreversible liquid damage.
Only use a microfiber cloth and don"t use chemicals to clean a resistive touchscreen.Disconnect the display from the power supply and remove any screen protectors or liners.
Isopropyl alcohol (IPA) is widely used to clean printed circuit boards (PCBs). Use a Q-tip or soft small bristle brush for scrubbing a PCB, and never use a paintbrush.Gently rub a Q-tip in Isopropyl alcohol.
Cleaning soldering residue on LCD with Isopropyl alcohol and a Q-Tip.Cleaning residue around soldering elements is not necessary if Newhaven Display performed the soldering.
Cleaning your electronic display is a simple task. However, it is essential to consider these steps to handle and clean it properly. You should now have a better understanding of what cleaning products are safe to use, how to clean the display screen glass, how to clean touchscreens and how to clean soldering residue.

The way you clean your computer screen largely depends on what it"s made of - you have to be more careful with LED/LCD screens than glass-coated ones.
We"ve all had that moment - you"re sitting at your desk on a normal workday, then the sun starts shining directly on your screen, and you realize you don"t know when you last cleaned it. In fact, it may have been so long that you"ve forgotten how you"re supposed to clean it.
If this sounds like you, don"t feel too bad - most experts recommend that you should only clean your computer screen every three to six months. So if you"ve waited half a year since the last time you cleaned, it makes sense that you might not remember all the do"s and don"ts of the process.
Here"s a helpful guide to help you remember exactly how to clean your specific computer screen, whether it"s a Mac or PC, including which products you should and shouldn"t use for your specific type of display.
Glass-coated screens: The screens you find on most Mac computers are glass-coated. Displays like this are a little less delicate than LED or LCD screens.
LED/LCD screens: These screens are mostly found on Windows computers. Unlike glass-coated screens, they"re made up of tiny liquid crystals and can be very easily damaged if you"re not careful. Most touchscreens and matte displays are LED/LCD.
You may want to look on your manufacturer"s website and check what kinds of solutions are safe for the screen type you have - factors like whether your screen is matte or a touchscreen may affect this.
If you have a glass-coated screen on your computer, you have a few more options as to what cleaners you can use, but you should still be careful. You can use one of the solutions listed above, but you can also use:
Turn off your computer before cleaning - this is just safe practice where any amount of liquid is involved, but more specifically, any static on the screen could create a shock and damage the internal components.
Use filtered or distilled water if you need to use it, especially in areas with hard water - minerals like calcium and magnesium in the water you use could also damage your screen.
Wipe in tight, Z-shaped motions, or directly up and down or side to side. Wiping in circles can create uneven pressure and ultimately lead to screen damage. It"s also more likely to create streaking.
Use any fabric that feels rough to the touch - even a fabric as soft as a cotton shirt has snags and uneven parts that can damage a computer screen. Microfiber cloths are ideal because the fibers are so tiny that they can cover every inch of the screen with even pressure at the same time, eliminating any opportunity for scratches.
Spray any cleaning solution directly onto the screen. To avoid any risk of damage from excess moisture, spray the solution directly onto the microfiber cloth instead.
Apply pressure when you clean the screen. This will likely damage the internal components of the screen and could leave scratches or spots of discoloration or dead pixels that won"t go away.
Even if you"re working on a particularly stubborn spot, don"t scrub - rather, leave the damp cloth sitting on the screen for several minutes, then try to gently wipe it away again.
Once you"ve turned off your computer and dusted off the screen, mist a dust-free side of your microfiber cloth with a cleaning solution that is safe for the type of screen you have.
Wipe the screen in a consistent, non-circular motion without applying too much pressure. Make sure no moisture accumulates, especially at the corners - if it does, use a dry corner of microfiber cloth to gently wipe it away.
Don"t make the mistake of thinking that LCD screens work like your nifty new iPad. In general, touching should be off limits because pressing too hard on the screen can actually break or crack pixels. So the first rule to cleaning an LCD screen is don"t do it unless you have to (i.e. unless it"s actually dirty).
Many retailers offer special cleaning solutions for LCD screens, but the truth is that most of these are made up primarily of water. So, if you don"t want to take the time to go buy a cleaner or you want to save the money (maybe to put toward that "What Not to Wear" dress), you can just make your own LCD cleaner by mixing water with some vinegar or isopropyl alcohol -- the solution should be no more than 50/50.
You could even start with plain water and see if you need the vinegar or alcohol, which will come in handy when you"re trying to wipe away greasy fingerprints. Some people recommend only using distilled water, but regular water works fine, according to Dave Chipman from Sharp.
Unless you want to end up with a melted, discolored, hazy or scratched LCD screen, steer clear of all spray cleaners. In particular, don"t use any solvent cleaners that include acetone, ethyl alcohol, ethyl acid, ammonia or methyl chloride. You also want to avoid using any materials that could potentially scratch the screen"s delicate surface. Opt for a soft, clean, cotton cloth instead of wood-based products like paper towels and tissues. Chipman suggests using a microfiber cloth for best results.
If you"re lucky enough to have a service come in and do your cleaning for you, make sure they don"t inadvertently ruin your television or monitor by trying to clean it with something like glass cleaner. You should either take the time to explain -- and maybe even demonstrate -- how you want your LCD screen cleaned or just ask your cleaner to leave this particular job for you.
If your screen is still dirty, apply a small amount of 70~75% isopropyl alcohol (IPA) solution to your cloth and gently wipe down the exterior of your screen. Alternatively, you can also use a 70~75% IPA wipe.
Keeping your precious rugged LCD monitors or LED screens clean and tidy can be challenging. This is especially true if you happen to have handsy young children who like to touch everything or pets running amuck in your household or even if you happen to work in a particularly messy environment such as a construction site or restaurant. Sometimes, rogue bits of debris can attach themselves to your electronic devices and while this is entirely out of your control for the most part, there are a few effective and harmless cleaning solutions you can put into practice to keep your electronics clean and running smoothly. Continue reading to learn about helpful tips for cleaning your LCD and LED screens without causing internal or external damage.
Before you can get down to the cleaning part, you need to prepare your LCD or LED screen in order to reduce the risk of liquids penetrating the surface and causing internal damage. Keep in mind that modern screens might technically include higher end features than the old school CRT screens from your childhood, but that doesn’t necessarily mean they’re more durable. In fact, modern LCD and LED screens are actually a lot more fragile and easily susceptible to damage if they’re not cared for properly. To prepare the screen for cleaning, make sure you shut down the system entirely, disconnect it from its power source, and then let it cool down for a few minutes. This will reduce the risk of electrocution and it’ll make it easier to clean the screen without resulting in annoying and unattractive streaks.
Occasionally, you’ll have to contend with a tough spot, streak, or fingerprint marking that takes a little extra effort to clean. If this happens, don’t panic and definitely don’t press down harder with a cloth or try to scrape it off with your fingernails or any other tool as this can cause severe damage to the top layer or anti-gloss coating. The best thing to do is use a non-abrasive cleaning solution such as isopropyl alcohol that’s diluted with either pure or distilled water. Spray the solution onto a microfiber cloth and gently wipe down the area in either an up and down or side to side motion. Applying too much pressure to even the most rugged touchscreen can compromise its limited durability.
There are a few types of cleaning cloths you can use to wipe down your rugged LCD monitor either at home or at work. The most recommended one is microfiber cloth for a multitude of reasons. First, microfiber is a state-of-the-art technological development that’s a thin and soft, yet strong enough material to thoroughly clean your electronic devices without risking damaging them in any way. Most of the time, computer and flatscreen TV manufacturers provide microfiber cloths with their products along with a specific set of maintenance and cleaning instructions. Microfiber cloths are immune to collecting or spreading lint across your screen, and because of the intricate way in which the minuscule fibers are intertwined these cloths are able to trap larger quantities of dirt and dust without leaving streaks. You can also use a cotton tea towel, a cotton t-shirt, or cotton handkerchief if you’re in a bind and don’t have microfiber cloths on hand.
This point can’t be emphasized enough. Even though it may seem like common sense that electronic devices shouldn’t come into direct contact with any liquids (especially if they’re still plugged in), not everyone seems to think so and many people have made the mistake of spraying cleaning agents onto their devices. The safer and smarter way to clean any rackmount LCD display is by first wiping it down with a dry cloth and then spraying a small amount of the cleaning solution onto a different cloth and wiping it down gently. After you do this, wipe it down with a clean dry cloth to remove any remaining liquid.
Always avoid using ammonia or rubbing alcohol based cleaners on your touchscreen devices. The devices themselves might be constructed with the capability to withstand most types of damages, but certain features they possess aren’t. Ammonia and rubbing alcohol can irreparably strip away or damage the extremely delicate anti-glare coating on the screen, which will not only negatively alter your viewing experience but also make your device a lot harder to use in strong sunlight.
Dust that settles between the gaps in the screen where the bezel and the top layer of glass or plastic meet can penetrate deeper and cause internal damage to your device. Regularly using a vacuum with a soft-bristled brush (to prevent scratching) can help you keep your device clean and free of any issues.
For extra measure, you can also spray the surface of your screen, computer keyboard, or even the vent on the back of the device with a can of compressed air to blast away any lingering and stubborn debris or dust. If any of it lands on the surface of the device, make sure to gently wipe it away with a clean cloth to prevent it from making its way back into your device. Implementing this cleaning method on a regular basis will ultimately help to guarantee the longevity and functionality of your device.

Cleaning your LCD computer screen is not quite as straightforward as cleaning a CRT computer screen. LCD screens are sensitive, and it is easier for them to become scratched or damaged. You can still clean your LCD computer screen, but you must be very careful.
Turn off your LCD computer screen on your monitor prior to cleaning. This enables you to see the areas that need to be cleaned, such as smudges and fingerprints.
It is important the you do not use any old cloth or paper product to clean your LCD screen. A microfiber cloth is less likely to scratch, or otherwise damage your screen.
When using the microfiber cloth to clean the screen, apply light pressure to remove dust, oil and other unwanted marks. Avoid using extra pressure on resistant areas.
If a dry microfiber cloth does not get the LCD screen totally clean, dampen the cloth with distilled or deionized water. If even that does not provide satisfactory results, you can combine equal amounts of white vinegar and distilled or deionized water, and use that solution for cleaning the LCD monitor. Alternatively, you can add a small amount of isopropyl alcohol to distilled water to help clean the LCD screen.
Paper towels, toilet paper, tissue paper and newspaper can scratch your LCD monitor, so never use them for cleaning it. Rely on a microfiber cloth instead.
Never use cleaning products that contain ammonia, ethyl alcohol, acetone, toluene, ethyl acid or methyl chloride. These chemicals can cause the screen to yellow, become brittle or even crack.
If a cleaning solution is sprayed onto the LCD screen, it is likely to run down the screen and cause damage. Always apply any water or cleaner to the microfiber cloth, and use the dampened cloth to clean the monitor.
Cleaning your LCD computer screen takes just a few minutes. All you need is a microfiber cloth, perhaps some distilled or deionized water, a bit of vinegar and a gentle touch.
Television screens are supposed to be clean and free of dirt, dust, or any debris that may blur vision. This is why this component is one of the most vital parts of a Television. Nothing can be worse than straining your eyes to make sense of the pictures your set is projecting. If you do not clean your TV regularly, fingerprint smudges and dust will build up.
Cleaning your LED TV or any type of television for that matter is something you should do at least once every 2 or 3 weeks. In fact, I will suggest that you do it as often as you watch it any paying more attention to the screen when you do so. If you clean your TV set regularly, it will always look brand new, and you will enjoy bright and colorful pictures without said. Bearing that in mind, there are ways to go about a cleaning endeavor. Unfortunately, not everyone knows how to clean a set effectively. Many think that a piece of towel soaked in water will do. How wrong they are. Television screens are very sensitive, so a great deal of care is required to do the job effectively. In addition to that, being careful also protects the screen for damage. Secondly, you need to understand that TV sets are different. Although they all project sounds and images, they are built differently. So, therefore, the approach to cleaning should also be different as well.
The approach to cleaning an LED TV screen, for instance, requires extra care compared to the cleaning of a Tube TV. They both have screens, but the former is more sensitive than the latter due to the sensitivity of LED screens build material. Bearing all this in mind, how do you safely clean an LED TV screen without damaging it in the process. In this article, we will show you safe and intelligent ways to go about it using available and affordable materials. You will also learn a few tips about how to do it safely too.
Before you proceed, you need to bear two things in mind when cleaning LED TV screens. Firstly, you want to do it in such a way and with the right materials that ensure the screen is clean and devoid of dust or stains of any kind. You want your screen to be as bright and clear as possible. Secondly, you want to avoid damaging the screen or reducing its projection quality. This is why it is necessary to use only the right cleaning materials and approach at all times. Now, here are some helpful tips for adopting when cleaning an LED television screen. [/fusion_text]
Every electronic equipment comes with an owner’s manual. This manual provides the user with sufficient information about how to use and maintain the gadget. The same thing goes for LED sets. They come with an owner’s manual too. Before you clean the set, you may want to read the manual first.
In fact, it is advisable that you read it first immediately you buy and install it in your home. By reading the manual, you gain more understanding regarding how to care for the television all through it a lifespan in your home, office, or wherever you install it. For the purpose of cleaning, pay attention to the section that provides information about how to do it effectively.
Reading manuals is important because different television manufacturers provide different approaches to cleaning their sets. What works for an LG LED TV may not work for a Samsung set. That is why it is so important to only follow the recommendation of a one cap fits all approach to cleaning your TV screen. If you read the manual when you bought it, but you have forgotten the cleaning details, consult it once again to refresh your memory.
Before you start the cleaning properly, turn off the television set. Do not stop at that. You also need to unplug it from the power source. Once you have done that, do not start cleaning the screen immediately. Give it time to cool down. The cleaning process may take between 2-5 minutes or even more depend on your LED TV model or how long it was on.
Turning the TV off will cut off power leading to the cooling down of the screen. You don’t want to be cleaning a hot or warm screen, do you? You want to make sure that the screen is as cool as possible and non-reactive to whichever cleaning agent you use.
Another advice to take in that is so important is that you should never use paper towels to clean the screen. There are reasons to avoid paper towels. Paper towels, especially when soaked in water, leave smudges and stains on the screen. No matter how long or how hard you try to wipe the marks off, they yet remain. Paper towels are bad for your TV screen. It’s as simple as that.
To enjoy an ultimate cleaning experience, you should consider using microfiber cleaning pieces. Some people recommend cotton whole because they are more breathable. However, microfiber cloths are more durable. In addition, they do not stick to your screen. Older LED, or LCD screens can’t handle traditional cleaning methods or materials. With microfiber, you can eliminate stains, remove smudges, and fingerprints with ease.
To use microfiber, simply wipe the surface of the screen in a circular motion. Cover as much part of the screen as you possibly can. Work your way around the edges as well. More importantly, when cleaning, avoid touching the screen with your bare hands as doing so will leave fingerprint marks on it.
The use of chemicals should be avoided at all costs. Chemicals damage screens more than you know. That a chemical agent worked on a particular surface is not an indication that it will work well for your TV screen. LED screens are very sensitive and fragile, so you ought to make sure that you keep chemicals as far away as possible. Another material you should never use is a detergent solution (water and detergent).
Soap, scouring powder, was window cleaners, and any other general industrial cleaner should be avoided. Abrasive pads and towels made from paper should not be used either. Using any of these materials will lead to screen scratches, anti-glare coating damage, or permanent screen damage. The sad part is that the damage may not be noticeable at first, but over time, the same will become permanent.
If you must wet your cleaning material with water, do so in little splashes. Avoid spraying the screen directly with water. When wiping the screen, do so gently because it can break if pressed too hard as screens are very fragile.
You will notice that your microfiber cloth cannot reach the edges of the screen like the other areas. If you don’t clean the edges too, dust and first will accumulate in those parts, and after a time removing the stains will love difficult. Furthermore, failure to clean screen edges will lead to an uneven appearance, with poor picture quality being the end result. To clean edges and corners effectively, use cotton swabs to greater effect. For better results, dab the cotton swabs in water. Pick off the dirt carefully by dragging them out using the swabs. Do this for the four corners of the screen.
As for the edges, run the swabs up and down systematically but avoid running them all the way down to the edges as this may drive dirt further on that may be difficult to remove. For better results, use as many cotton swabs as you can.
Unlike an LED TV screen, cleaning a Tube TV is much easier. Tube TV screens are more rugged and can withstand pressure, but doing so carefully is also important. You can use a microfiber cleaning cloth doused in a little water. Never spray the screen directly as this may damage it. Rather, work your way with the microfiber cloth. Apply the same circular cleaning motion like you would do an LED TV screen. Cotton swabs will also come in handy to pick off the dirt from the screen corners.
Dish soap can also be used on LED and LCD screens, albeit with care. Before you use a dish soap solution, first wipe the screen with a dry cloth to remove dust. Now, dip your cleaning cloth in the dish soap solution. Squeeze off the liquid then gently wipe the screen. Make sure you cover every surface area. Once you are done, don’t waste time to clean; otherwise, the solution will dry up on the screen leading to a blurry vision. Rinse the cloth with water to remove soapy residue then take the dry cloth you used to wipe off the dust once again to dry the screen.
Yes, they do. There are actually cleaners specially made for cleaning tv screens. Screen cleaners contain distilled water, isopropyl, and alcohol solutions. If you must use an electronic screen cleaner, make sure you shake to content before use. Also, apply on a limited portion of your cleaning cloth.
Cleaning your TV remote control is part of a general TV cleaning process. So to clean your remote control, follow these tips. Pop-out the batteries:Remove the batteries from the remote. Doing so will create enough room when cleaning the interior casing.
Tap the remote lightly on a hard surface:Remote controls gather a lot of dust and debris along the way. To remove them, tap the remote control on a hard surface like a table. Do this gently and several times to dislodge debris stuck in crevices.
Use a mild disinfectant:Apply a cleaning disinfectant on a piece of cloth and clean the body thoroughly. The use of disinfectant is necessary because our hands carry germs, and we transfer these germs to the remote control anytime we operate it. Clean the whole body thoroughly.
Maintain a weekly timetable:To ensure that your TV set is always clean, make sure you clean it weekly. Add it as part of your to-do list when cleaning your home. If your furniture deserves regular cleaning, so does your television set. Doing regular cleaning will atop dust, debris and fingerprints from smearing the screen. It is also much easier to clean when there is little dust on the surface. Keeping a microfiber cloth close by is also advised so that you can quickly wipe off dust when necessary.
Never spray your LED TVset directly with any substance:Avoid spraying your screen directly with any substance even if it is an electronic cleaning gel. Excessive spraying can damage the cabinet and the structural make-up of the screen. If you must use any cleaning solution, apply it on the napkin or microfiber cloth you are using and gently wipe the screen with it.
Use a Vacuum:To draw out dust and debris hidden in the crevices of the set, use a low suction vacuum. You may also use the vacuum cleaner’s soft brush to remove dust from the cable, vents, and ports of the TV
Adhere strictly to the User Manual:Your LED TV set comes with a user manual for a reason. The manual is meant to guide your use of the device. When cleaning your set, make sure you follow the directives of the manufacturer. Doing it any other way may damage the TV beyond repair.
Avoid strong cleaning agents:Just like we pointed out in the article, avoid strong cleaning agent as not all of them are good for your television’s screen. The screen is very sensitive, so bear this in mind. Some examples of cleaning agents to avoid include unmixed alcohol, ammonia, acetone, and Wax.
Maintaining your LED TV set requires a lot of patience and attention to detail. If you want the screen to remain in good shape, you need to clean it regularly and with proper cleaning materials. If you follow the tips in this article, your screen will remain bright and sharp for as long as you use the set.
Remember when your computer LCD display had that brand-new, fresh out-of-the-box shine? If it"s looking a little dull lately, it might be time to give it a good cleaning. Here"s how:
Step 2:Gently wipe the dust from the surface of the display using a dry, lint-free cloth, like a microfiber cloth. Remove any tags that may be on the cloth to avoid scratching the display with the tags.
If you prefer, you can use a cleanser made specifically for cleaning LCD displays, but do not spray it directly onto the display. Spray a small amount of the cleaner onto a microfiber cloth first, to avoid getting any cleaning solution inside the display.

A.The input of ITO glass: According to the requirements of the product, appropriate ITO glass is selected and put into the transfer basket. Specifications and models of ITO glass are required to meet the requirements of the product. Remember that the ITO layer must be inserted into the basket upward.
B. Cleaning and drying of glass: Clean ITO glass with the cleaning agent and deionized water (DI water), wash impurities and oil stains on the ITO surface with physical or chemical methods and then remove and dry the water to ensure the processing quality of the next process.
C.Photoresist coating: Evenly coat a layer of photoresist on the conductive surface of ITO glass. The glass coated with photoresist must be pretreated at a certain temperature: (as shown in the figure below)
D.Pre-drying: The glass coated with a photoresist is baked for a period of time at a certain temperature to volatilize the solvent in the photoresist and increase its adhesion to the glass surface.
E.Exposure: Ultraviolet light (UV) is used to illuminate the surface of the photoresist through the pre-made electrode pattern mask, which causes the reaction of the photoresist layer. The photoresist is selectively exposed under an ultraviolet lamp by covering the photoresist on the glass coated with the photoresist (as shown in the figure).
F.Development: the surface of the glass is treated with developer solution, the photoresist layer decomposed by light is removed, the photoresist layer of the unexposed part is retained, the photoresist of the part exposed by UV light is dissolved in the developer solution by chemical method, the developed glass has to undergo a certain temperature hardening film treatment.
H.Etching: With appropriate acid etching solution, the ITO film without photoresist covering is etched off. Thus, the required ITO electrode pattern is obtained.
Note:is conductive glass (In2O3 and SnO2), which is easy to react with acid and is used to etch off the excess ITO to obtain the corresponding wire electrode.
I.Film removal: the high concentration of alkali solution (NaOH solution) is used as the film removal solution to peel off the remaining photoresist on the glass, thus forming ITO graphics exactly consistent with the lithography mask on the ITO glass.
General TN and the STN product does not require this step, the TOP film coating process is after the photolithography process making SiO2 coating, once again to the etching area and the etching area between the grooved bridge and the electrode covering, this can have the effect of the insulation layer, and can effectively eliminate the display state of the bottom electrode, also help to improve the perspective characteristics and so on, so most of the high-grade product requires TOP coating.
This process involves coating an oriented layer on the etched ITO glass surface and treating the restricted layer in a specific way so that the liquid crystal molecules can be oriented (arranged) in a specific direction on the surface of the oriented layer. This step is unique to the production of liquid crystal displays.
Organic polymer-oriented material is coated on the surface of the glass, that is, a uniform orientation layer is applied to the appropriate position of ITO glass by a selective coating method, and the orientation layer is cured at the same time. (Usually in the display area)
Flannelette material is used to rub the surface of the oriented layer in a specific direction so that the liquid crystal molecules can be arranged along the friction direction of the oriented layer in the future. For example, TN type friction orientation: 45 degrees
In this process, two conductive glasses are stacked on top of each other, and sealed together, and cured to make a glass box with a specific thickness of clearance. The technology of box-making is one of the key technologies in LCD manufacturing. (Spacing of LIQUID crystal boxes must be strictly controlled)
Evenly distribute the supporting material over the lower glass. A certain size of the liner (usually a few microns) is evenly distributed over the surface of the glass. These materials are used to ensure that the spacing between the glasses is the thickness of the box.
press the upper and lower glass against each other on the counterpoint mark, and then glue the corresponding two pieces of glass face to face with sealing material.
Curing the sealing material at high temperatures. When curing, the pressure is applied to the upper and lower glass to make the spacing of the liquid crystal boxes (thickness remains uniform).

STONE provides a full range of 3.5 inches to 15.1 inches of small and medium-size standard quasi TFT LCD module, LCD display, TFT display module, display industry, industrial LCD screen, under the sunlight visually highlight TFT LCD display, industrial custom TFT screen, TFT LCD screen-wide temperature, industrial TFT LCD screen, touch screen industry. The TFT LCD module is very suitable for industrialcontrol equipment, medical instruments, POS system, electronic consumer products, vehicles, and other products.
Important technical improvements of LCD, such as LED backlighting and wide viewing Angle, are directly related to LCD. And account for an LCD display 80% of the cost of the LCD panel, enough to show that the LCD panel is the core part of the entire display, the quality of the LCD panel, can be said to directly determine the quality of an LCD display.
The production of civil LCD displays is just an assembly process. The LCD panel, the main control circuit, shell, and other parts of the main assembly, basically will not have too complex technical problems.
Does this mean that LCDS are low-tech products? In fact, it is not. The production and manufacturing process of the LCD panels is very complicated, requiring at least 300 process processes. The whole process needs to be carried out in a dust-free environment and with precise technology.
The general structure of the LCD panel is not very complex, now the structure of the LCD panel is divided into two parts: the LCD panel and the backlight system.
Due to the LCD does not shine, so you need to use another light source to illuminate, the function of the backlight system is to this, but currently used CCFL lamp or LED backlight, don’t have the characteristics of the surface light source, so you need to guide plate, spreadsheet components, such as linear or point sources of light evenly across the surface, in order to make the entire LCD panel on the differences of luminous intensity is the same, but it is very difficult, to achieve the ideal state can be to try to reduce brightness non-uniformity, the backlight system has a lot to the test of design and workmanship.
In addition, there is a driving IC and printed circuit board beside the LCD panel, which is mainly used to control the rotation of LCD molecules in the LCD panel and the transmission of display signals. The LCD plate is thin and translucent without electricity. It is roughly shaped like a sandwich, with an LCD sandwiched between a layer of TFT glass and a layer of colored filters.
LCD with light refraction properties of solid crystals, with fluid flow characteristics at the same time, under the drive of the electrode, can be arranged in a way that, in accordance with the master want to control the strength of the light through, and then on the color filter, through the red, green, blue three colors of each pixel toning, eventually get the full-screen image.
According to the functional division, the LCD panel can be divided into the LCD panel and the backlight system. However, to produce an LCD panel, it needs to go through three complicated processes, namely, the manufacturing process of the front segment Array,the manufacturing process of the middle segment Cell, and the assembly of the rear segment module. Today we will be here, for you in detail to introduce the production of the LCD panel manufacturing process.
The manufacturing process of the LCD panel Array is mainly composed of four parts: film, yellow light, etch and peel film. If we just look at it in this way, many netizens do not understand the specific meaning of these four steps and why they do so.
First of all, the motion and arrangement of LCD molecules need electrons to drive them. Therefore, on the TFT glass, the carrier of LCD, there must be conductive parts to control the motion of LCD. In this case, we use ITO (Indium Tin Oxide) to do this.ITO is transparent and also acts as a thin-film conductive crystal so that it doesn’t block the backlight.
The different arrangement of LCD molecules and the rapid motion change can ensure that each pixel displays the corresponding color accurately and the image changes accurately and quickly, which requires the precision of LCD molecule control.ITO film needs special treatment, just like printing the circuit on the PCB board, drawing the conductive circuit on the whole LCD board.
First, the ITO film layer needs to be deposited on the TFT glass, so that there is a smooth and uniform ITO film on the whole TFT glass. Then, using ionized water, the ITO glass is cleaned and ready for the next step.
Next, a photoresist is applied to the glass on which ITO film is deposited, and a uniform photoresist layer is formed on the ITO glass. After baking for a period of time, the solvent of the photoresist was partially volatilized to increase the adhesion of the photoresist material to the ITO glass.
Ultraviolet light (UV) is used to illuminate the surface of the photoresist through a pre-made electrode pattern mask, which causes the photoresist layer to react. The photoresist is selectively exposed under ultraviolet light by covering the photoresist on the glass coated with the photoresist.
The exposed part of the photoresist is then washed away with the developer, leaving only the unexposed part, and the dissolved photoresist is then washed away with deionized water.
Then etch off the ITO film without photoresist covering with appropriate acid etching solution, and only retain the ITO film under the photoresist. ITO glass is conductive glass (In2O3 and SnO2). The ITO film not covered by photoresist is easy to react with acid, while the ITO film covered by photoresist can be retained to obtain the corresponding wire electrode.
Stripping: High concentration of alkali solution (NaOH solution) is used as a stripping solution to peel off the remaining photoresist on the glass so that ITO glass can form ITO graphics exactly consistent with the photolithography mask.
Rinse the basic label of glass with an organic solution and remove the photolithographic tape after reaction to keep the glass clean. This completes the first thin-film conductive crystal process, which generally requires at least five identical processes to form a complex and sophisticated pattern of electrodes on the glass.
This completes the previous Array process. It is not difficult to see from the whole process that ITO film is deposited, photoresist coated, exposed, developed, and etched on TFT glass, and finally, ITO electrode pattern designed in the early stage is formed on TFT glass to control the movement of LCD molecules on the glass. The general steps of the whole production process are not complicated, but the technical details and precautions are very complicated, so we will not introduce them here. Interested friends can consult relevant materials by themselves.
The glass that the LCD board uses makes a craft also very exquisite. (The manufacturing process flow of the LCD display screen)At present, the world’s largest LCD panel glass, mainly by the United States Corning, Japan Asahi glass manufacturers, located in the upstream of the production of LCD panel, these manufacturers have mastered the glass production technology patents. A few months ago, the earthquake caused a corning glass furnace shutdown incident, which has caused a certain impact on the LCD panel industry, you can see its position in the industry.
As mentioned earlier, the LCD panel is structured like a sandwich, with an LCD sandwiched between the lower TFT glass and the upper color filter. The terminal Cell process in LCD panel manufacturing involves the TFT glass being glued to the top and bottom of a colored filter, but this is not a simple bonding process that requires a lot of technical detail.
As you can see from the figure above, the glass is divided into 6 pieces of the same size. In other words, the LCD made from this glass is finally cut into 6 pieces, and the size of each piece is the final size. When the glass is cast, the specifications and sizes of each glass have been designed in advance.
Then, the organic polymer directional material is coated on the surface of the glass, that is, a uniform directional layer is applied to the appropriate position of ITO glass by the method of selective coating. Meanwhile, the directional layer is cured.
Directional friction:Flannelette material is used to rub the surface of the layer in a specific direction so that the LCD molecules can be arranged along the friction direction of the aligned layer in the future to ensure the consistency of the arrangement of LCD molecules. After the alignment friction, there will be some contaminants such as flannelette thread, which need to be washed away through a special cleaning process.
After the TFT glass substrate is cleaned, a sealant coating is applied to allow the TFT glass substrate to be bonded to the color filter and to prevent LCD outflow.
Finally, the conductive adhesive is applied to the frame in the bonding direction of the glass of the color filter to ensure that external electrons can flow into the LCD layer. Then, according to the bonding mark on the TFT glass substrate and the color filter, two pieces of glass are bonded together, and the bonding material is solidified at high temperatures to make the upper and lower glasses fit statically.
Color filters are very important components of LCD panels. Manufacturers of color filters, like glass substrate manufacturers, are upstream of LCD panel manufacturers. Their oversupply or undersupply can directly affect the production schedule of LCD panels and indirectly affect the end market.
As can be seen from the above figure, each LCD panel is left with two edges after cutting. What is it used for? You can find the answer in the later module process
Finally, a polarizer is placed on both sides of each LCD substrate, with the horizontal polarizer facing outwards and the vertical polarizer facing inwards.
A polarizer is an optical plate that allows only light from a certain direction to pass through. It is an optical element that converts natural light into straight polarized light. The mechanism of action is to make the vertical direction light pass through the straight incident light after passing through the vertical polarizer, and the other horizontal direction light is absorbed, or use reflection and scattering and other effects to make its shade.
When making LCD panel, must up and down each use one, and presents the alternating direction, when has the electric field and does not have the electric field, causes the light to produce the phase difference and to present the light and dark state, uses in the display subtitle or the pattern.
The rear Module manufacturing process is mainly the integration of the drive IC pressing of the LCD substrate and the printed circuit board. This part can transmit the display signal received from the main control circuit to the drive IC to drive the LCD molecules to rotate and display the image. In addition, the backlight part will be integrated with the LCD substrate at this stage, and the complete LCD panel is completed.
Firstly, the heteroconductive adhesive is pressed on the two edges, which allows external electrons to enter the LCD substrate layer and acts as a bridge for electronic transmission
Next is the drive IC press. The main function of the drive IC is to output the required voltage to each pixel and control the degree of torsion of the LCD molecules. The drive IC is divided into two types. The source drive IC located in the X-axis is responsible for the input of data. It is characterized by high frequency and has an image function. The gate drive IC located in the Y-axis is responsible for the degree and speed of torsion of LCD molecules, which directly affects the response time of the LCD display. However, there are already many LCD panels that only have driving IC in the X-axis direction, perhaps because the Y-axis drive IC function has been integrated and simplified.
The press of the flexible circuit board can transmit data signals and act as the bridge between the external printed circuit and LCD. It can be bent and thus becomes a flexible or flexible circuit board
The manufacturing process of the LCD substrate still has a lot of details and matters needing attention, for example, rinse with clean, dry, dry, dry, ultrasonic cleaning, exposure, development and so on and so on, all have very strict technical details and requirements, so as to produce qualified eyes panel, interested friends can consult relevant technical information by a search engine.
LCD (LC) is a kind of LCD, which has the properties of light transmission and refraction of solid Crystal, as well as the flow property of Liquid. It is because of this property that it will be applied to the display field.
However, LCD does not emit light autonomously, so the display equipment using LCD as the display medium needs to be equipped with another backlight system.
First, a backplate is needed as the carrier of the light source. The common light source for LCD display equipment is CCFL cold cathode backlight, but it has started to switch to an LED backlight, but either one needs a backplate as the carrier.
CCFL backlight has been with LCD for a long time. Compared with LED backlight, CCFL backlight has many defects. However, it has gradually evolved to save 50% of the lamp and enhance the transmittance of the LCD panel, so as to achieve the purpose of energy-saving.
With the rapid development of LED in the field of lighting, the cost has been greatly reduced.LCD panels have also started to use LED as the backlight on a large scale. Currently, in order to control costs, an LED backlight is placed on the side rather than on the backplate, which can reduce the number of LED grains.
However, no matter CCFL backlight or LED backlight is placed in various ways, the nature of the backlight source cannot be a surface light source, but a linear light source or point light source. Therefore, other components are needed to evenly distribute the light to the whole surface. This task is accomplished by the diffuser plate and diffuser plate.
On the transparent diffuser plate, point-like printing can block part of the light. The LED backlight on the side drives the light from the side of the diffuser plate, and the light reflects and refracts back and forth in the diffuser plate, distributing the light evenly to the whole surface. Point-like printing blocks part of the light, screening the light evenly like a sieve.
At the top of the diffusion plate, there will be 3~4 diffuser pieces, constantly uniform light to the whole surface, improve the uniformity of light, which is directly related to the LCD panel display effect. Professional LCD in order to better control the brightness uniformity of the screen, panel procurement, the later backlight control circuit, will make great efforts to ensure the quality of the panel.
The backlight system also includes a backlight module laminator, located behind the backplane. In the CCFL backlight era, you can often see the long strip laminator like the one above, with each coil responsible for a set of tubes.
However, it is much simpler to use a side white LED as a backlight. The small circuit board on the far left of the figure above is the backlight of the LED.
This is the general structure of the backlight system. Since I have never seen the backlight mode of R.G.B LED, I cannot tell you what the backlight mode is like. I will share it with you when I see it in the future.
Since the LCD substrate and the backlight system are not fixed by bonding, a metal or rubber frame is needed to be added to the outer layer to fix the LCD substrate and the backlight system.
After the period of the Module, the process is completed in LCM (LCDModule) factory, the core of this part of the basic does not involve the use of LCD manufacturing technology, mainly is some assembly work, so some machine panel factories such as chi mei, Korea department such as Samsung panel factory, all set with LCM factories in mainland China, Duan Mo group after the LCD panel assembly, so that we can convenient mainland area each big monitor procurement contract with LCD TV manufacturers, can reduce the human in the whole manufacturing and transportation costs.
However, neither Taiwan nor Korea has any intention to set up factories in mainland China for the LCD panel front and middle manufacturing process involving core technologies. Therefore, there is still a long way to go for China to have its own LCD panel industry.
Regularly cleaning your LCD monitor keeps it free of dust, smudges, and germs. Wiping with a dry microfiber cloth is the safest cleaning option and is surprisingly effective at removing germs. You may need to use a dampened microfiber cloth to get rid of stubborn smudges and stuck-on debris, though. If you"re worried about germs, consider using a vinegar and water solution or a Lysol wipe on the screen. Be sure to check the device’s user manual first to make sure it’s okay to use liquids!
Whether you’re gaming or burning the midnight oil on a work project, there’s nothing more annoying than a dirty computer screen. The only problem is that most computer screens are highly sensitive and require a delicate touch to prevent damage.
If you’ve ruined a monitor before or you want to keep that brand new laptop running smoothly, this article will provide you with all the information you could possibly need to keep your screen squeaky clean without damaging it.
Wondering how to clean your laptop screen without causing any damage? You don’t have to be a tech guru to understand that any kind of liquid getting into the hardware of your laptop spells disaster. Because of this, you should avoid liquid sprays.
One of the most common mistakes people make when attempting to clean their laptop computer screens is using a liquid cleaner. As a general rule, try to avoid them altogether, however, there are few safe liquid substances you can carefully use to clean laptop screens.
If you aren’t having much luck with a dry cloth or if you spilled something on your screen, you can try using a bit of rubbing alcohol (for non-LCD screens) if you don’t want to buy a specified cleaning product.
The trick, of course, is to not let any of the liquid get down to the speakers or keyboard and to use an extremely small amount - just enough to remove the dirty spot.
If you have an LCD screen, do not use rubbing alcohol as it will damage your screen. If you’re unsure about what products are safe for your laptop or you aren’t completely sure what kind of screen you have, look up the products that the manufacturer lists as restricted for cleaning.
With the right cloth or material, a cleaning substance may be completely unnecessary. Microfiber cloths are the best possible material to clean your PC with, since paper towels, household rags, and old T-shirts will scratch and damage your screen.
Of course, there will be instances where no amount of gentle wiping will remove the soda your toddler spilled on your laptop a week ago. In these circumstances, you may have to turn to a serious computer cleaning solution or rubbing alcohol. Just remember that when you clean your laptop’s screen, a delicate touch is vital to the long-term health of your display.
Sometimes you can’t splurge on ultra-expensive products when trying to clean your laptop screen and you have to rely on alternative methods. There are plenty of household items that can be used, such as rubbing alcohol. However, there are some that are dangerous to your screen which you should try to avoid.
A brand new sponge is a great way to clean a screen. You will need to lightly dampen the sponge (but not too much); the last thing you want is for water to drip down into your laptop.
If, and only if, you have a glass laptop screen, it’s safe to use Windex as a cleaner. Sturdier computers sometimes have a clear glass screen over the front of the display - much like a cell phone. A bit of Windex sprayed onto your microfiber cloth will certainly get the job done. But remember, never spray the Windex directly onto your laptop screen itself.
If you don’t have a microfiber cloth or a sponge fresh out of the package, a soft duster brush will work. A traditional feather duster might damage your screen but there’s a good chance you’ve adopted the Swiffer® duster into your household. These cleaning cloths are made from thousands of tiny polyester fibers and are the next best thing for cleaning your screen if you don’t have a microfiber cloth.
If you ever find yourself questioning the methods by which you plan to clean your laptop screen, it’s best to err on the side of caution. To take extra precaution, you can order specialized products and cleaning solutions online or pick them up at electronic stores.
Compressed gas is one of the best places to start when learning how to clean your laptop. Not only is this product great for removing the dust on your screen, but it’s also good for cleaning your keyboard as well. Dust-Off®, Endust®, and Fellowes® are all solid and reliable brands of compressed air that have withstood the test of time. They are available at grocery stores, drug stores, and computer stores, as well as many online retailers.
Bryson Screen and Laptop Cleaner is a reasonably inexpensive cleaning solution that’s as easy to use. Just spray it onto a screen-safe cleaning cloth and wipe away all of your worries.
The i-ScreenClean Ball 3-Pack is a great tool for daily cleaning and maintenance. With the i-ScreenClean ball, you can entirely avoid the use of liquids while you clean your laptop screen or monitor. Bigger problems like spills and stains will require the use of professional cleaning products, but for the most part, the cleaning ball is a great way to go.
The corners of your monitor or laptop screen are often the most difficult and frustrating to clean. Fortunately, cleaning brushes for detailing are available. The Oxo Good Grips cleaning brush is perfect for reaching into the corners of your laptop’s display. This tool will allow you to avoid the use of liquids and give your laptop a complete clean.
You can find most of these products online or at computer stores along with wipes and other cleaning supplies that were specifically designed for laptop screens and monitors.
Once you’ve cleaned your laptop screen, try to keep it that way. One of the primary reasons your screen continues to get dirty so often is because of your keyboard. Dead skin cells, dirt, and grime from your fingertips get on the keyboard and transfers to your laptop’s screen when you close it.
One of the best ways to prevent this transference of dirt and grime is to place a thin microfiber cloth on top of your keyboard every time you close your computer.
If you know that you’re not going to use your laptop for an extended period, be sure to keep it stored in a sealed computer bag or plastic bag. Dust and dirt can easily build up in a matter of days if your laptop is left out in in the open. You should always store your laptop whenever you’re not using it; doing so will prevent dust from building up inside the hardware.
The best thing about touch screens, especially tablets and smartphones, is that they usually come with an additional protective screen that makes it much easier to clean. However, you should still take the same precautions that you would with a standard laptop screen.
While touch screen laptops aren’t always made of the same materials that traditional smartphones and tablets are, they may often be just as sensitive. The best thing to do is pick up a microfiber cloth and give your screen a gentle wipe down using the same techniques previously mentioned.
Unless you plan to wash your hands before each time you use your touch screen laptop, you should make an effort to clean it far more frequently. All that grime on your fingertips dragging across your screen can cause a major build up.
Touch screens are especially sensitive to pressure, so make sure you don’t press down too firmly while you’re cleaning since it could wear out the sensors or even damage them. You will also want to turn your screen off before cleaning. You wouldn’t want to accidentally send out a strange jumbled-up email to an important client while you’re cleaning.
When learning how to clean your monitor or laptop screen, it’s always better to be safe than sorry. You invested a significant amount in your laptop and other electronics. It would be wise to invest a small amount in their care and upkeep. Investing in a microfiber cloth that you keep in your desk just for your laptop, along with a cleaning solution kit might cost you a few bucks but it will cost you far more to replace a damaged computer screen from careless cleaning.
TOKYO (Reuters) - Japan’s Sharp Corp, a leading supplier of displays to Apple Inc, said Thursday it will form a $2.9 billion alliance with state-owned China Electronics Corp that includes an agreement by Sharp to license its advanced power-saving IGZO screen technology.
The new venture will be 92 percent owned by China Electronics, also known as CEC, which supplies equipment to China’s military. The venture will set up a an LCD plant with the goal of mass-producing panel displays for televisions, notebook PCs and tablets in 2015.
Licensing IGZO, or indium gallium zinc oxide displays, fits into a strategy by cash-strapped Sharp to leverage its technology to bolster its finances. Sharp, in December, signed a pact with Qualcomm Inc, selling the U.S. company an equity stake for $120 million and agreeing to develop new screens based on IGZO technology.
IGZO screens boast power consumption as low as a tenth of conventional LCDs, high resolutions and faster reaction speeds. While an agreement to license the technology to a Chinese military-linked state company may raise eyebrows, Sharp does not exclusively own the technology, only being the first to commercialize it.
The agreement, which is a revised version of one agreed to with CEC in 2009, may instead represent a retreat by the Chinese company to win access to Sharp’s more advanced tenth-generation LCD manufacturing techniques. CEC is planning to build an 8.5 generation facility.
Sharp is the only panel maker in the world to have built a tenth generation factory able to fabricate liquid crystal sandwiched in glass sheets thinner than a credit card that are 3.13 meters long by 2.88 meters wide. Smaller 8.5 generation sheets measure 2.2 meters by 2.5 meters.
CEC in November blamed deteriorating ties between Japan and China over their territorial spat in the East China Sea for shelving cooperation with Sharp to build a tenth-generation facility. Sharp, which sold a stake in its advanced LCD plant to Taiwan’s Hon Hai Precision Industry last year, says no such agreement ever existed.
Thursday’s deal, including the construction of the 8.5 generation factory in Nanjing, represents one of the highest-profile transactions between a Chinese and Japanese company since tensions flared last year over a chain of disputed islands known as the Senkakus in Japan and the Diaoyu in China.
A Sharp spokesman declined to say how much i
