how to repair lcd display supplier
Liquid crystal displays (LCDs) are the most widely used display technology. Their applications cover TV, mobile phone, appliances, automotive, smart home, industrial meters, consumer electronics, POS, marine, aerospace, military etc. LCD screen display problem can occur for several reasons.
Effect of environmental conditions on the LCD assembly. Environmental conditions include both the effects of temperature and humidity, and cyclic loading.
Effect of manufacturing process. With the development of LCD for more than 40 years and the modern manufacturing equipment, this kind if defects are getting rear.
Common failures seen in LCDs are a decrease in screen contrast, non-functioning pixels or the whole display, and broken glass. Different kinds of LCD display problem need to have different kinds of fix methods or make the decision not worthwhile to repair.
Broken glassIf you accidently drop the LCD and you find it broken on the surface but the display still works. You might just break the touch panel; you can find a repair house or find a youtube video to replace the touch panel. If you find the display not showing, especially you find the fluid leaking out. You need to reply the whole display modules.
Dim LCD displayLCD can’t emit light itself. It uses backlight. Normally, the backlight is not fully driven, you can increase the LED backlight to make a dim LCD display brighter. But if you LCD display has been used for a long time, it is possible that the LED backlight has to be the end of life (not brightness enough) if you turn on 100% backlight brightness. In that case to fix LCD screen, you have to find a way to change the backlight. For some display, it is an easy job but it can be difficult for other displays depending on the manufacturing process.
Image sticking (Ghosting)Sometimes, you will find the previous image still appearing at the background even if you change to another image. It is also called burn in. This kind of failure doesn’t need to repair by professionals. You can simply shut off the display overnight, this kind of problem will go away. Please do remember that displaying a static image for a long time should be avoided.
With the modern manufacturing process and design, this kind of failure rarely happens. Normally, it is caused by no power. Please check if the battery dead or adapter (power supply) failure or even check if you have plug in firmly or with the wrong power supply. 99% the display will be back on.
LCD has white screen – If a LCD has a white screen which means the backlight is good. Simply check your signal input sources which are the most causes. It can also be caused by the display totally damaged by ESD or excess heat, shock which make the LCD controller broken or the connection failure which has to be repaired by professionals.
Blur ImagesAs the LCD images are made of RGB pixels, the screen shouldn’t be blur like old CRT displays. If you do see blur images, they might be caused by two reasons. 1) LCD has certain response time, if you are playing games or watch fast action movies, some old LCD displays can have image delays. 2) The surface of the LCD is made of a layer of plastic film with maximum hardness of 3H. If you clean the surface often or use the wrong detergent or solvent which cause the surface damage. To fix damage on LED screen it’s need to be changed with professionals.
If you have any questions about Orient Display displays and touch panels. Please feel free to contact: Sales Inquiries, Customer Service or Technical Support.
If the picture responds to input but displays a messy image, such as jumbled multicolored squares, the AV (audio visual) board may be damaged. This is usually a rectangular circuit board located near the audio and visual cables. Replace obviously damaged parts using a soldering iron, or order a replacement board and carefully install it to the same screws and ribbon cables.
The main control buttons may be faulty. Clean them with a metal cleaner, or jostle to attach a loose connection. If necessary, locate the circuit board they are attached to and re-solder any broken connections.
Check input cables for damage, or try other cables of the same type. If necessary, inspect the circuit board they are attached to and re-solder damaged connections.
With an array of different timing profiles and the use of a video-signal generator, full testing is available on most display models we can offer support for.
CRT Monitors: given the nature of the CRT displays, repairing them is often not a viable option. To a large extent this depends on the severity of the damage. When something fails within a CRT display, it often triggers deterioration of other components at the same time. This sometimes leads to a repaired CRT monitor fail again and again, even after a thorough repair.
When a CRT monitor is damaged beyond repair, we have a wide range of different retrofit options available to help get that machine back up and running with an even brighter and clearer image compared to the original monitor.
How to repair LCD displays? Three visual inspection methods can help you solve problems, including external inspection, internal inspection and electrical inspection.
(1) External inspection: LCD display inspection should start from the outside, according to the working mode of the machine to check whether the buttons and switches on the operation panel are normal, whether the power connection is good, whether the video signal line is normal, etc.
(2) Internal inspection: LCD display in the external inspection did not find any abnormalities, open the display shell, check the internal circuit. Observe whether the solder joints and connecting wires of components are virtual soldering, de-soldering, whether the pins are mildewed or not, whether the plug-ins are loose, whether the circuit lines of printed circuit boards are broken, whether the components are burnt, burst or leakage, etc.
(3) Electricity check: LCD display is connected to the power switch to observe whether the power indicator light is on, whether there is fire, fever, burning odor and smoking in the machine.
People often ask how to repair the LCD display. In fact, this is a very professional problem, because precision instruments can not be explained in one word or two, so today I will tell you
3. #If all the above is OK, measure the LVDS voltage value. Under normal conditions, the LVDS signal’s RX+/ RX-voltage value is about 1.2v, and RX+/ RX-difference value is about 200mV. At the same time, the resistance of the LVDS signal to ground and the resistance between the LVDS signal pairs can be measured (100 ohms). If there is an exception to these values, try replacing the ASIC.
2. #Confirm whether the VAA is normal (normally about 17V). If abnormal, disconnect the RP32 to confirm whether it is caused by DC/DC loop or X-side COF: disconnect RP32, if the VAA is normal, the COF is bad, CO must be changed; COF can be Disconnect one by one to determine which NG disconnects RP32, VAA NG, try to change UP1; at the same time, confirm whether the continuity of the surrounding triode is OK.
1. #Measure GM1~GM14, the values are arranged from large to small. In general, a certain gamma value will be abnormal in the case of NG, then try to replace gamma-IC;
3. #Confirm whether the RSDS value is correct, normal RSDS is about 1.2v, and the signal difference is about 200mV; At the same time, we can confirm the resistance between RSDS signal (normal 100 or 50 ohms) and RSDS resistance to ground. If the voltage is NG, check if the ASIC and X-COF are hot.
Polarizer / CELL damaged To change the polarizer, a polarizer attaching machine is required The degree of whitening of the picture changes with different viewing angles
1. #Adjust the VR knob to see whether it can be adjusted and whether the screen performance changes. At the same time, confirm the VCOM value (about 7v), if NG, replace the VR knob.
2. #Confirm VGH/VGL voltage (about 30V VGH and -6v VGL), and confirm whether it is DC/DC loop NG or COF IC NG; The corresponding resistance of disconnected VGH and VGL can determine whether it is a DC/DC problem or a COF-IC problem. If it is DC/DC NG, try to replace UP1 or confirm whether the corresponding transistor is OK.
2. #Confirm whether there is 12V input, if not, confirm whether the connector is OK, and confirm the resistance value of 12V voltage to earth; If conn. NG, change conn.; If 12V is short-circuited to the ground, disconnect FP1 to determine the short-circuiting circuit.
B. Confirm VAA resistance to ground at VAA test point of R plate (A short circuit usually occurs), disconnect the corresponding capacitance of the following 3 COF, and confirm VAA resistance to the ground again. If OK, replace the capacitor, if NG, replace COF. If VAA is still NG, confirm DC/DC loop as all models.
6. #Disconnect RP32 to confirm VAA, if NG, try to change the PWM IC (in general, it will be good), if still NG, try to change the gamma-ic or corresponding to the VAA several large capacitances (in general, it is rare, this situation is generally accompanied by VAA to the ground short circuit).
4. #Press the LCD glass side of the panel, if the vertical lines disappear or reappear, it can be judged that the cause of poor contact, OM checking should be able to find the poor contact.
5. #If there is no display change in pressing, confirm whether ITO is damaged under the OM microscope, or pin signal waveform corresponding to needle COF.
3. #Disassemble the backlight, confirm whether there is a short circuit with broken skin on the lamp strip, whether the plug of the lamp strip is fully integrated with the socket, whether the pin is aslant/off, whether the connector is off, and whether the LED bead is black and injured.
4. #The fault of the product is basically caused by the above reasons. If the appearance is fault-free, the lamp bar can be crossed to confirm whether the phenomenon follows the lamp bar, or the voltage of the lamp bar and the conduction condition between the lamp beads can be measured.

When your LCD display has broken, needs replaced or simply needs a technology upgrade, and you have design/equipment elements to consider, you will want to look for a replacement part instead of replacing the unit.Problems may arise when you are sourcing the new panel from your original manufacturer.For example, by the time your panel has degraded, your LCD may be end of life, making it difficult to source;original manufacturers may be charging premium prices for their replacementLCD parts.AGDisplays offers a drop in replacement service for customers who need to replace an LCD or LCD component when their original panel/part is unavailable;this service is also for customers who are looking for a cost effective, suitable replacement or upgrade to their existing LCD. AGDisplays offers availability of standard or custom high-quality LCDs of virtually all shapes and sizes.
Replacing or upgrading the LCD component of your equipment sounds intimidating. It is rather simple if you begin your search with AGDisplays. By simply providing us with your panel part number, general specifications (if possible) and any other upgrade requirements or desires that you might have, we source these products for you or we can source an equivalent replacement, as desired. Using a replacement LCD does not compromise on quality and compatibility;we ensure functionality and performance are top priority because we know how critical the LCD interface is for your application.
You may receive notifications from your original equipment manufacturer about your LCD panel. There are a couple of announcements to pay attention to. The most important two are the end of life (EOL) announcement and the end of sale date. The end of life announcement will officialize a future cease production date for the indicated part number. It may also indicate the end of sale date, which is the last date customers are able to order the product through the manufacturer. After this date, the product will no longer be for sale. Typically end of life announcements come six to twelve months before the last time buy date. A few months later is when your last time buy will ship.
If you decide by this point that your equipment is well suited to use the LCD replacement, you may want to grab these panels when they get into the last time buy phase. If you find yourself ready to upgrade after EOL and last time buys have passed, don’t fret.A drop in replacement unit extends the lifecycle of your unit in the case of EOL or unavailability of original parts. Products are matched for compatible integration without compromising quality. AGDisplays offers a full line of compatible replacement industrial LCD display systems.

There are many signs an LCD will give the user to indicate that it may be due for replacement or upgrade. Even users who are not LCD experts will be able to tell when it is time to replace.
Outwardly, your LCD will show physical signs of damage such as a cracked or scratched, foggy or contaminated screen.Mostly, these damages are quickly noticeable to the naked eye and the first obvious sign that your panel may need a replacement. These are clear indications that the outside of your LCD has been damaged and is in need of evaluation or replacement. The application environment will determine the urgency in which you’ll want to replace the LCD. Cracks in the LCD may leave the LCD vulnerable to contamination and dust, which in turn can extend damage and/or decrease visual readability of the display.
Most LED technology estimate LED lifetimes to be upwards of 100,000 hours of useful life. This works out to be about six hours of usage a day—and 45 years of service, whew! So one can assume that LCD components will fail before the LED backlighting system will degrade. However, degradation does happen with long term usage. If your LCD is looking less bright than it should be, it is possible that a component in the display’s backlighting system needs replaced or upgraded.
LCDs that are broken internally may only show a black screen, a white screen, or even show no data when turned on. Other indications will be white/grey/black discoloration spots (called mura) of the display itself when it is turned on, regardless of the data/color that is shown on screen.
Another indication of a dying LCD aredamaged pixels. If you notice a small speck of white or black on your screen that does not go away, even as the screen changes, you may have a damaged pixel or two. There are a few different types of pixel defects, hot, stuck and dead pixels. Hot pixels present themselves as always ‘on,’ they always appear white in color. Dead pixels are always ‘off,’ and look black at all times. Now a stuck pixel is either stuck ‘on’ or ‘off’ so they may appear the same as a hot or dead pixel. These (sometimes) are solved by switching from bright to dark colored screens quickly to unstick these. However, this isn’t a reliable treatment for stuck pixels.
If you’ve notice defective pixels on your LCD screen, do not panic! Some manufacturers have a standard in which it allows a certain amount of pixels in production. Overall, if the LCD in question has an increased rebellion of pixels, whether hot, dead or stuck, the LCD may be of low quality or the pixels are going bad.
Sometimes white, black or multi colored streaks appear running horizontally or vertically along the display. If this is happening on every screen, this is a likely sign that something is wrong inside the LCD.
Signs of LCD degradation include those missing pixels, the dimming of screen brightness over time, and even the loss of color and contrast in a display. If you need more assurance the LCD is the problem, consult AGDisplays to discuss our replacement options.
Broken screen replacement service is provided from thousands of repairs stores and phone parts wholesalers worldwide, iPhone of which are mostly engaged in. So how to purchase reliable LCD screens among so many quality grades from China suppliers? Let me firstly elaborate on the quality grades of the iPhone LCD digitizer assembly that most repair stores and traders used to replace the broken ones.
According to the investigation, 90% of the Chinese iPhone LCD screen suppliers are found selling third-party manufactured screens and seldom sell genuine original LCD screens. Therefore, if your phone screen is broken, there would be a high chance for your screen to be replaced with a non-original one. Why? Maybe the cost and quality are relatively competitive, so why not?
As known, Foxconn is authorized to assemble iPhone, so there are some original iPhone LCD screens leaked from the assemble factory. And there are brought out from the factory for replacement. However the price is definitely high and still, some people care more about the quality of the screen than how much they cost, so for this group of customers, the Original Quality of LCD digitizer assemblies are preferred.
For some LCD digitizers, the LCDs are still working while the front glasses are broken, which can be recycled. Some factories recycled these broken screens by removing the broken front glass and attach a new one, then the LCD digitizer assembly would be new again, which is what called refurbished. Brand new original LCD screens are limited, and the refurbished ones can replenish the shortage of the new original LCD digitizer assemblies, for their quality would be more stable than the third-party manufactured.
Some Chinese factories purchase the original single LCD display, not compete LCD screen from the original factory, and then attach high copy front glass, backlight, etc, materials into a complete LCD screen, which quality is not stable and the display color is slightly different from the ones with high copy backlight. Well, their price would be cheaper and loved by many repair shops and wholesalers.
Under the shortage of original LCD screens, many Chinese factories begin to produce the high copy LCD screen. The stock and supply are getting less and less since about 2015, which leads the price goes higher and higher. Therefore the Chinese manufacturer starts to produce LCD screens with high copy raw materials. With competitive prices and good quality that meet most iPhone users’ needs, they are also popular among many wholesalers and repair shops.
With the premium quality of LCD and OLED screens tested strictly, we’ve helped many clients enlarge their markets worldwide. If you wholesale the LCD digitizer assembly or retail them in your repair shop, more information and sample are supported for your reference, please do not hesitate to contact us or leave your comment to discuss more.
Finding a TFT LCD replacement can sometimes be a challenge. Just recently TFT display manufactures, such as Seiko Display products and Standish Displays have discontinued production of all their LCD display modules; these, of course, include Thin-Film-Transistor Displays (TFT).
Other LCD suppliers have discontinued production of selected TFT models, requiring many OEM customers to quickly locate another LCD supplier for their current production needs.
We receive calls and e-mails asking us to find a drop-in equivalent TFT displays. The customer’s goal is to locate a LCD module that will be 100% interchangeable with their current product. Sometimes this is easy and does not require any tooling or modifications cost; other times the customer will need to invest in a one-time tooling fee.
Modifying the size or dimensions of the TFT glass is not a good option. The cost to modify TFT glass is very, very expensive. On previous custom TFT LCD designs, we have seen tooling cost starting at $500K, and this does not include the extremely high Minimum Order Quantities (MOQ) involved with such a modification. Unless you are a Google, Amazon or Microsoft, choose a standard size glass.
If your product requires a unique size of TFT glass, redesign your product to accept a standard size glass or switch to a different LCD technology such as OLED or FSC. This will save you money and reduce the number of headaches.
There are other modifications that may be necessary to manufacture a TFT display this is 100% equivalent. This includes the relocation of the cable, the lengthening of the cable, adding a resistive touchscreen or increasing the brightness of the backlight. All of these can be accomplished with a much lower tooling cost and acceptable MOQs.
TFT display manufactures choose backlight brightness for their product. The brighter the backlight, the more the displays stands out, but also the more power that is required to drive. This is a key element to consider if your product is battery powered or you have a limited power budget.
We are able to modify our current TFT LCD Displays and increase their brightness with a low (one-time) tooling cost. Let us know what intensity you require and we will make the necessary adjustments.
Ocular LCD Displays is the latest LCD supplier to pull out of the display market. Consequently, we have been contacted by people asking us for replacement displays once supplied by Ocular USA Displays.
Ocular LCD Displays has moved towards chapter 7. They were located in Texas and began business in 1986. It looks like they ceased delivering displays in mid-November of 2014.
Focus Displays Solutions has been in the LCD business for over fourteen years, in that time we have focused on custom LCDs and replacement LCDs for Ocular USA, Seiko LCDs and Standish Displays.
We not only sell replacement displays, but offer US-based technical support to provide quick responses and US-based inventory. In many cases we can ship you samples the same day you call.
This is not only true for discontinued Ocular LCD Displays, but for LCD suppliers that are still in business, but have discontinued a specific LCD product line.
Whether the LCD has been discontinued by Ocular LCD Displays, Seiko, Standish or other LCD suppliers, Focus Displays has been carrying inventory and offering reverse engineering support to help customers quickly located inventory for their display.
Our technical support people may be able to offer an off-the-shelf standard display with a short lead-time or even zero lead-time. If your Ocular LCD display was a custom, we are able to design and build a solution from your data sheets or from an actual display module.
Focus Displays holds inventory in our Chandler, AZ warehouse and can offer many equivalent displays from stock. If it is necessary for Focus to build a prototype sample, all the LCD glass is shipped via fed ex air, so lead times for large orders are a few weeks and not a few months.
Discovering that your current LCD display manufacture has discontinued your LCD Display is never a welcome surprise. Without a drop in equivalent LCD module you may have to discontinue manufacturing or re-design your product to integrate a new LCD replacement. This can be a frustrating experience, very expensive and time-consuming.
The first step is for the customer to contact Focus Displays at 480-503-4295 and send the data sheets for the LCD that you were using. If you do not have a current data sheet or there is a concern that it may not be accurate, Focus may be able to ‘estimate’ a cost from a photo.
If you are not able to supply a data sheet from Ocular LCD Displays and we are not able to locate it, then the next option is to reverse engineer the display. This is where you would send us two displays (these can be non-working) units that we can take apart and create a schematic and electrical characteristics
Below is our process flow chart to explain the steps necessary to move from concept to full production. More details on developing a custom LCD can be located at
Once a LCD supplier discontinues a display, they tend to remove any documentation from their web site. This lack of data sheets increase the amount of work and lead-time required to generate a quote and build samples. In some cases the old LCD supplier has been purchased by another company and much of their documentation is missing.
If you find that your current module supplier has discontinued your display, contact us for support to help you locate a replacement LCD display. We may have old documentation to reduce your lead-time of locating an equivalent display.
If your displays are custom Ocular LCD displays or it is not a standard off-the-shelf display that we hold in inventory, a tooling fee may be necessary. The tooling fee, also called a NRE (Non-Recurring Engineering), is one-time cost that can run anywhere from $500 to $5,000 dollars.
If you pay the tooling fee, then you own the design. We will only sell this display to you or to who you authorize. If another customer contacts us for the same display, we would forward that customer to you or Focus will contact you and notify you there is a customer looking for your custom LCD.
In the past we have tooled up replacement displays and then directed future business to that customer. The customer that paid us the tooling fee can then purchase the displays from us and resell them to another customer.
In some cases, a second customer will offer to repay half of the tooling cost to the first customer for the rights to purchase the display from Focus.
There have been times when a customer required a replacement display and we felt that this would be a popular display for us to hold in our inventory and sell to our LCD customers.
Each technology requires different MOQs (Minimum Order Quantities). If the MOQ is too high for your current demand, we can put you in touch with a distributor who can hold that inventory for you and allow you to take delivery over several drops.
Will I be able to order samples to test before I need to place a large production order? The answer is yes, when you pay the one-time tooling cost for the Ocular replacement display, we offer samples at no cost.
Many times the customer does not require the replacement display for a product they are still manufacturing, but for repairs. Many products, such as cell phones, credit card readers and test equipment will be in the field for several years after production has ended and will require spare units.
Since Focus Displays is building an equivalent display to fill your shortage, why not make improvements on the design? Improvements in LCD technology allow for upgrades such as: Brighter backlights, wider viewing angle, sharper contrast and even lower operating voltages.
It is possible to replace the older LED’s (Light Emitting Diode) with a newer, brighter and even less power consuming LED. Advantages would be a brighter backlight, less battery drain and possibly a longer half-life of the backlight.
What is the half-life of a backlight? Backlights slowly dim over time. The term half-life is the time, in hours, of how long the backlight can operate before its brightness is at 50%, or half, of what it originally was when first turned on.
Another solution to improve the LED backlight is to replace the current limiting resistor used on the LED with a lower value resistor that will allow the backlight to shine brighter. One down side to this is the reduction of half-life of the LED backlight. This may or may not be a concern for your product.
Speak to one of our LCD specialist to determine the best solution for you. If need be, we can sell you a display with the brighter backlight configuration for you to test and show your end customer.
Even light flow with no hot spots (hot spots is a condition of LEDs where the LED is too close to the glass, or the diffuser is not spreading the light evenly.)
DISADVANTAGES OF EL BACKLIGHTS INCLUDEEL backlights require an AC (Alternating current) signal. To generate an AC signal, an inverter must be installed either on the customers board or on the LCD itself.
The popularity of EL Backlights has decreased in the last few years. Over 95% of new product designs no longer incorporate an EL backlight, but instead choose a LED backlight or LED edge-lit configuration. Many products needing a replacement display were manufactured several years ago when EL backlights were common. Your Ocular LCD displays may contain an EL backlight. Many LCD suppliers no longer support EL backlight technology. Focus Displays is able to supply EL backlights, although the MOQ at this time is between 500 and 1K units.
It is not possible to replace an EL backlight with a LED backlight since EL is AC driven and LED is DC (Direct Current). Switching between the two, would require the customer to modify their PCB (Printed Circuit Board) to remove the inverter and add two traces, or contacts to connect the A( Anode) and K(cathode) of the LED backlight.
In the past, older LCD technology was limited to a smaller operating temperate range. New types of Nematic fluids and ITO (Indium tin oxide) glass now allow many displays to operate as low as -30C. We are able to offer these wider temperature ranges with minimal cost increase. In many cases, the LCDs we sell are the wide temperature range. There is no extra NRE cost to convert from a standard temperature display to a wide temperature. If your Ocular LCD displays were used in a product that operates outside, we recommend a wide temp. If the product is used indoors, it is possible to use normal temperature. If you do not know where the product operates, we recommend a wide temperature version.
Older LCD technologies were limited in backlight color to yellow/green. Now there is a much wider selection. You can choose a new backlight color to be integrated into your display with minimal or no extra cost. Below are photos showing the different backlight colors. The two most popular colors are Blue/White and Black/White. Additional colors include: yellow/green, grey, blue, white, red, orange, pure green, amber and others.
16X2 ALPHANUMERIC LCD, TRANSFLECTIVE (WORKS WITH OR WITHOUT THE BACKLIGHT), AMBER SIDE-LIT BACKLIGHT, FSTN, WIDE TEMP, BOTTOM VIEW (6:00), POSITIVE MODE
16X2 ALPHA-NUMERIC LCD, TRANSFLECTIVE (WORKS WITH OR WITHOUT THE BACKLIGHT), PURE GREEN SIDE-LIT BACKLIGHT, STN GREY, BOTTOM VIEW (6:00), POSITIVE MODE
16X2 ALPHANUMERIC LCD DISPLAY, TRANSFLECTIVE (WORKS WITH OR WITHOUT THE BACKLIGHT), WHITE LED SIDE-LIT BACKLIGHT, FSTN, BOTTOM VIEW (6:00), POSITIVE MODE
LEDs can create hot and cold spots when placed too close to the top layer of ITO glass. Most of the time the light can be ‘smoothed’ out with a diffuser (a diffuser is similar to a lamp shade that spreads out the light to an even glow), but the brighter the LED backlight is driven, the greater the chances of hot spots.
Focus Displays is able to help reduce or remove hotspots on your older discontinued LCD module by using new diffuser technology, or decreasing the brightness and increasing the quantity of LEDs.
The majority of LCD technologies require an onboard controller driver to be attached to the display. The exception to this is a segmented display that is interfaced with a 4:1 multiplex or direct drive.
Below is a photo of a COB (Chip on Board) configuration showing the controller/driver. The controller driver is under the black tab that holds the IC chip to the PCB and also protects it from humidity.
Our goal in working to replace your Ocular LCD displays, or any discontinued LCD, is to provide you the same controller driver chip. If the chip on the replacement display is the same as the chip used on your discontinued display, your firmware (aka the customer’s software) will run fine and the characters and fonts will display correctly.
If the new controller is different than the controller used on your Ocular LCD displays, you may need to modify your firmware. When designing the replacement display, we ask the customer to contact their current supplier to clarify which controller chip was used, but if your supplier has discontinued manufacturing of displays, this will not be possible.In this case, send us two of the displays and we will be able to identify which controller was used. If the new controller chip does not work and you are in need of assistance to modify your software, contact Focus Displays and we can put you in touch with a design house that specializes in this type of work.
Focus Display Solutions specializes in supplying replacement LCD Displays for discontinued and obsoleted LCD Display modules.

Over the years, LCD modules and LCD displays have grown in popularity. Companies in many different industries, including but not limited to the medical, automotive, consumer, food services, industrial, and technology sectors rely on at least one TFT LCD module or TFT LCD display on a daily basis. Although touchscreens are very durable and designed to withstand the hands of time, older modules and displays sometimes need to be repaired. When weighing the cost of having your displays repaired, you should take the time to consider your options.
After doing some research on the cost of repairs, many business owners find that it makes more sense to have their TFT LCDs replaced. Although units may cost less to repair initially, the cost of having to repair your older displays over and over again can add up. This is because older units may need to be repaired more than once. Even if multiple repairs will not cost any additional money, repairs lead to downtime and can have a tremendous impact on your business.
Older units in need of repair can have a long-term impact on a company’s bottom line. This is because outdated displays do not perform as well as new and improved displays. As many business owners have come to discover, new and improved touchscreen technology can increase efficiency, boost productivity, and improve customer satisfaction. This a top reason why so many companies decide to have a TFT LCD display or module replaced.
If you are thinking about having your older touchscreens repaired, then you should consider how having newer technology in place will help your business grow. Focusing strictly on the cost of replacing your displays can have a long-term impact on your business in more ways than one. For better results, you should consider all of the benefits of having new custom touchscreens specifically manufactured for your business. Ultimately, having new and improved displays in place for your employees and customers to use will be a business decision that pays for itself over time.
I have a TASCAM DR-05 audio recorder that has a monochrome orange LCD whose display has partially been damaged. Only the bottom half can be read while the top half is blank. I would like to attempt to change out the LCD by finding a replacement. I need help in finding a source for a replacement LCD. I’ve included a picture of the LCD on the PC Board just in case it might help. Would you please be able to point me in the right direction? Thanks in advance for your time and help.
P.S. I am aware it is not worth the effort to repair and it would definitely be more prudent to just buy another DR-05. That’s not the point. It’s a personal challenge to see if I can fix it. This is purely for fun, therefore no need to be tempted to let me know that I should just buy another DR-05. It’s not what I want to do. Thanks.
For most customers, visiting a professional repair provider with certified technicians who use genuine Apple parts is the safest and most reliable way to get a repair. These providers include Apple and Apple Authorized Service Providers, and Independent Repair Providers, who have access to genuine Apple parts.* Repairs performed by untrained individuals using nongenuine parts might affect the safety of the device or functionality of the display. Apple displays are designed to fit precisely within the device. Additionally, repairs that don"t properly replace screws or cowlings might leave behind loose parts that could damage the battery, cause overheating, or result in injury.
Depending on your location, you can get your iPhone display replaced—in or out of warranty—by visiting an Apple Store or Apple Authorized Service Provider, or by shipping your iPhone to an Apple Repair Center. Genuine Apple parts are also available for out-of-warranty repairs from Independent Repair Providers or through Self Service Repair.*
The iPhone display is engineered together with iOS software for optimal performance and quality. A nongenuine display might cause compatibility or performance issues. For example, an issue might arise after an iOS software update that contains display updates.
* Independent Repair Providers have access to genuine Apple parts, tools, training, service guides, diagnostics, and resources. Repairs by Independent Repair Providers are not covered by Apple"s warranty or AppleCare plans, but might be covered by the provider"s own repair warranty. Self Service Repair provides access to genuine Apple parts, tools, and repair manuals so that customers experienced with the complexities of repairing electronic devices can perform their own out-of-warranty repair. Self Service Repair is currently available in certain countries or regions for specific iPhone models introduced in 2021 or later.

If additional damage is found, you could pay an additional fee.
