lcd panel no screen factory

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.

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.

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.

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.

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.

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.

My monitor is not turning on even though it is plugged in (external power supply)First, try another device in the same outlet to determine if the outlet is working properly.

Is everything firmly plugged in? It is easy for cables to become loose and not firmly connected, especially if you are using a mobile system. Please check to ensure everything is securely plugged in.

The LED light on the power supply should be GREEN. If the LED light is not on, then either the power supply is dead or there is no power being generated from the power source. Try another power source (outlet) and if this doesn’t work, there may be an issue with the power adapter.

Amber Light: The amber light indicates the monitor is receiving power but is not receiving the video signal being fed from the signal source (camera, computer, etc). This may also signify that the monitor is currently set to the wrong video input; you may need to press the “Auto/Switch” button to select the appropriate input (VGA, HDMI, etc).

My monitor is not turning on even though it is plugged in (internal power supply)First, try another device in the same outlet to determine if the outlet is working properly.

Is everything firmly plugged in? It is easy for cables to become loose and not firmly connected, especially if you are using a mobile system. Please check to ensure everything is securely plugged in.

Amber Light: The amber light indicates the monitor is receiving power but is not receiving the video signal being fed from the signal source (camera, computer, etc). This may also signify that the monitor is currently set to the wrong video input; you may need to press the “Auto/Switch” button to select the appropriate input (VGA, HDMI, etc).

My monitor screen is completely black, even though it is powered onIs everything firmly plugged in? A loss of video signal will cause the monitor to go black and then turn off entirely. It is easy for cables to become loose and not firmly connected, especially if you are using a mobile system. Please check to make sure everything is securely plugged in.

Your monitor possibly has TRU-Vu’s Dim-To-Black feature which allows you to control the screen’s brightness and contrast by pressing the arrow keys in the menu. The reason it has gone completely black could be because the dim-to-black was turned all the way down. Press the arrow up to the right to raise the brightness again. If this does nothing, try pressing the left arrow keys.

Why does my monitor keep entering sleep mode when I turn it on?The primary cause is usually that the monitor is not receiving a video signal from the signal source (camera, computer, etc). The monitor will automatically enter sleep mode if it cannot detect a video signal.

If the LED on the monitor is amber, this means the monitor is receiving power but not receiving a video signal from your source. Ensure the monitor is set to the correct input and try swapping out sources to determine if that is the root of the problem.

Why are there black bars and/or squeezing (banding) with my monitor?If there are black bars around your signal and/or a “squeezing” effect, this means that the aspect ratio of your monitor and the incoming video signal do not match.

Make sure the monitor’s picture size setting is set to the factory default, not zoom, fit or stretch. For optimal picture quality without distortion, black bars or squeezing, it is always best to match the aspect ratio of your video signal with the aspect ratio of the monitor.

How do I know if my monitor is really showing true 4K video?Make sure that that the signal you are sending is 4K resolution (3840x2160). You can test this by pressing the monitor’s Menu button. The monitor’s Menu screen will display the incoming video resolution and timing in the top-right corner of the screen.

My touch screen is not working.All touch panels must be connected to a computer via USB or RS232 cable. This allows the touch panel to communicate with the computer.

If you recently downloaded a new touch panel driver, you must also delete the old driver and reboot your computer. Make sure you have deleted any old touch panel drivers and then restart your computer.

My touch screen is not registering correctlyAll non-HID compliant touch panels will need to be calibrated during the initial start-up and may need recalibrating at some other point in the future. This is accomplished via the touch panel software installed on your computer. For a detailed walk through, please contact us.

Certain touch panels are susceptible to issues due to grease/dust/water and therefore may need added care. If this is a constant problem, please contact us for further assistance.

The buttons on my monitor are lockedKeylock is a safety feature offered by TRU-Vu to prevent unauthorized personnel from changing the desired monitor settings. We do not publish the lock codes for public knowledge; please contact us for the unlock codes.

I increased the Brightness setting on my Sunlight Readable monitor, and now the image is washed outIf you would like to achieve a brighter image than the default settings on a TRU-Vu SRM-Series Sunlight Readable monitor, we recommend keeping the Brightness setting at the default setting (you may need to perform a factory reset/recall if you’ve already adjusted the Brightness), and then increase the contrast.

The speakers are not very loud on my monitorTRU-Vu speakers are provided for signals and alerts; these are not intended for voice or music. If quality of sound is a major concern, we advise using external speakers.

Prepare the screen by turning it off and wait until it is cool to the touch. Cleaning warm or hot screens makes it more difficult to clean and can even damage the screen.

It is always recommended to spray the microfiber cloth first, then clean the screen with the moistened cloth. Do NOT spray the monitor screen directly.

For heavier duty cleaning, create a solution of 80% alcohol mixed with 20% water and use the damp, not wet, cloth to clean the screen and panel surface.

I need to clean my monitor screen (with protective glass)We highly recommend WHOOSH Screen Cleaner. It is 100% natural, non-toxic, and environmentally friendly. You can also use any standard glass cleaner.

Flat-panel displays are thin panels of glass or plastic used for electronically displaying text, images, or video. Liquid crystal displays (LCD), OLED (organic light emitting diode) and microLED displays are not quite the same; since LCD uses a liquid crystal that reacts to an electric current blocking light or allowing it to pass through the panel, whereas OLED/microLED displays consist of electroluminescent organic/inorganic materials that generate light when a current is passed through the material. LCD, OLED and microLED displays are driven using LTPS, IGZO, LTPO, and A-Si TFT transistor technologies as their backplane using ITO to supply current to the transistors and in turn to the liquid crystal or electroluminescent material. Segment and passive OLED and LCD displays do not use a backplane but use indium tin oxide (ITO), a transparent conductive material, to pass current to the electroluminescent material or liquid crystal. In LCDs, there is an even layer of liquid crystal throughout the panel whereas an OLED display has the electroluminescent material only where it is meant to light up. OLEDs, LCDs and microLEDs can be made flexible and transparent, but LCDs require a backlight because they cannot emit light on their own like OLEDs and microLEDs.

Liquid-crystal display (or LCD) is a thin, flat panel used for electronically displaying information such as text, images, and moving pictures. They are usually made of glass but they can also be made out of plastic. Some manufacturers make transparent LCD panels and special sequential color segment LCDs that have higher than usual refresh rates and an RGB backlight. The backlight is synchronized with the display so that the colors will show up as needed. The list of LCD manufacturers:

Organic light emitting diode (or OLED displays) is a thin, flat panel made of glass or plastic used for electronically displaying information such as text, images, and moving pictures. OLED panels can also take the shape of a light panel, where red, green and blue light emitting materials are stacked to create a white light panel. OLED displays can also be made transparent and/or flexible and these transparent panels are available on the market and are widely used in smartphones with under-display optical fingerprint sensors. LCD and OLED displays are available in different shapes, the most prominent of which is a circular display, which is used in smartwatches. The list of OLED display manufacturers:

MicroLED displays is an emerging flat-panel display technology consisting of arrays of microscopic LEDs forming the individual pixel elements. Like OLED, microLED offers infinite contrast ratio, but unlike OLED, microLED is immune to screen burn-in, and consumes less power while having higher light output, as it uses LEDs instead of organic electroluminescent materials, The list of MicroLED display manufacturers:

LCDs are made in a glass substrate. For OLED, the substrate can also be plastic. The size of the substrates are specified in generations, with each generation using a larger substrate. For example, a 4th generation substrate is larger in size than a 3rd generation substrate. A larger substrate allows for more panels to be cut from a single substrate, or for larger panels to be made, akin to increasing wafer sizes in the semiconductor industry.

In the vast majority of cases, this has addressed the black screen issue. This usually indicates an app is causing stability problems. If this is the case for you, begin troubleshooting apps by disabling or uninstalling them until the device works normally again.

If the previous step doesn’t work, the only other option to fix a black screen after turning on an Android device is a factory reset. This will wipe the device of all your personal data so should only be attempted as a last resort and after backing up your data if possible.

One of today’s modern technological wonders is the flat-panel liquid crystal display (LCD) screen, which is the key component we find inside televisions, computer monitors, smartphones, and an ever-proliferating range of gadgets that display information electronically.What most people don’t realize is how complex and sophisticated the manufacturing process is. The entire world’s supply is made within two time zones in East Asia. Unless, of course, the factory proposed by Foxconn for Wisconsin actually gets built.

Last week I had the opportunity to tour BOE Technology Group’s Gen 10.5 factory in Hefei, the capital of China’s Anhui Province.This was the third factory, or “fab” that Beijing-based BOE built in Hefei alone, and in terms of capability, it is now the most advanced in the world.BOE has a total of 12 fabs in Beijing, Chongqing, and several other major cities across China; this particular factory was named Fab 9.

Liquid crystal display (LCD) screens are manufactured by assembling a sandwich of two thin sheets of glass.On one of the sheets are transistor “cells” formed by first depositing a layer of indium tin oxide (ITO), an unusual metal alloy that you can actually see through.That’s how you can get electrical signals to the middle of a screen.Then you deposit a layer of silicon, followed by a process that builds millions of precisely shaped transistor parts.This patterning step is repeated to build up tiny little cells, one for each dot (known as a pixel) on the screen.Each step has to be precisely aligned to the previous one within a few microns.Remember, the average human hair is 40 microns in diameter.

On the other sheet of glass, you make an array of millions of red, green, and blue dots in a black matrix, called a color filter array (CFA).This is how you produce the colors when you shine light through it.Then you drop tiny amounts of liquid crystal material into the cells on the first sheet and glue the two sheets together.You have to align the two sheets so the colored dots sit right on top of the cells, and you can’t be off by more than a few microns in each direction anywhere on the sheet.The sandwich is next covered with special sheets of polarizing film, and the sheets are cut into individual “panels” – a term that is used to describe the subassembly that actually goes into a TV.

For the sake of efficiency, you would like to make as many panels on a sheet as possible, within the practical limitations of how big a sheet you can handle at a time.The first modern LCD Fabs built in the early 1990s made sheets the size of a single notebook computer screen, and the size grew over time. A Gen 5 sheet, from around 2003, is 1100 x 1300 mm, while a Gen 10.5 sheet is 2940 x 3370 mm (9.6 x 11 ft).The sheets of glass are only 0.5 - 0.7 mm thick or sometimes even thinner, so as you can imagine they are extremely fragile and can really only be handled by robots.The Hefei Gen 10.5 fab is designed to produce the panels for either eight 65 inch or six 75 inch TVs on a single mother glass.If you wanted to make 110 inch TVs, you could make two of them at a time.

The fab is enormous, 1.3 km from one end to the other, divided into three large buildings connected by bridges.LCD fabs are multi-story affairs.The main equipment floor is sandwiched between a ground floor that is filled with chemical pipelines, power distribution, and air handling equipment, and a third floor that also has a lot of air handling and other mechanical equipment.The main equipment floor has to provide a very stable environment with no vibrations, so an LCD fab typically uses far more structural steel in its construction than a typical skyscraper.I visited a Gen 5 fab in Taiwan in 2003, and the plant manager there told me they used three times as much structural steel as Taipei 101, which was the world’s tallest building from 2004- 2010.Since the equipment floor is usually one or two stories up, there are large loading docks on the outside of the building.When they bring the manufacturing equipment in, they load it onto a platform and hoist it with a crane on the outside of the building.That’s one way to recognize an LCD fab from the outside – loading docks on high floors that just open to the outdoors.

LCD fabs have to maintain strict standards of cleanliness inside.Any dust particles in the air could cause defects in the finished displays – tiny dark spots or uneven intensities on your screen.That means the air is passed through elaborate filtration systems and pushed downwards from the ceiling constantly.Workers have to wear special clean room protective clothing and scrub before entering to minimize dust particles or other contamination.People are the largest source of particles, from shedding dead skin cells, dust from cosmetic powders, or smoke particles exhaled from the lungs of workers who smoke.Clean rooms are rated by the number of particles per cubic meter of air.A class 100 cleanroom has less than 100 particles less than 0.3 microns in diameter per cubic meter of air, Class 10 has less than 10 particles, and so on. Fab 9 has hundeds of thousands of square meters of Class 100 cleanroom, and many critical areas like photolithography are Class 10.In comparison, the air in Harvard Square in Cambridge, MA is roughly Class 8,000,000, and probably gets substantially worse when an MBTA bus passes through.

Since most display manufacturing has to be done in a cleanroom and handling the glass requires such precision, the factory is heavily automated.As you watch the glass come in, it is placed into giant cassettes by robot handlers, and the cassettes are moved around throughout the factory.At each step, robots lift a piece of glass out of the cassette, and position it for the processing machines.Some of the machines, like the ones that deposit silicon or ITO, orient the glass vertically, and put them inside an enormous vacuum chamber where all the air is first pumped out before they can go to work.And then they somehow manage to deposit micrometer thin layers that are extremely uniform.It is a miracle that any of this stuff actually works.

The Hefei Gen 10.5 is one of the most sophisticated manufacturing plants in the world.On opening day for the fab, BOE shipped panels to Sony, Samsung Electronics, LG Electronics, Vizio, and Haier.So if you have a new 65 or 75-inch TV, there is some chance the LCD panel came from here.

To learn how to manually download and install a device driver such as Chipset, Video card (GPU), and Monitor driver (if required, most monitor drivers are delivered automatically through Windows Update) on your Dell computer, see the Dell knowledge base article How to Download and Install Dell Drivers.

We must verify whether the problem is the display screen of the laptop, video card (GPU), or video settings on the computer. A straightforward way to identify this is to connect the laptop to an external monitor or TV.

If the issue persists on the external monitor, it may be an issue with the video card (GPU) or video settings and not the laptop LCD panel. Go to verify display or video issues in Windows Safe Mode. Otherwise, go to the next step.

Performance issues may occur if there is any damage to the LCD screen. The display may stop working, work intermittently, flicker, display horizontal or vertical lines, and so on, if there is damage to the display screen.

If you notice a physical damage, contact Dell Technical Support to learn more about repair options that are available in your region. If there is no damage, go to the next step.

Dell laptops have integrated diagnostic tools that can determine if the screen abnormality is an inherent problem with the LCD screen of the Dell laptop or with the video card (GPU) and computer settings.

When you notice screen abnormalities like flickering, distortion, clarity issues, fuzzy or blurry images, horizontal or vertical lines, color fade, running a diagnostic test on the LCD helps identify if the issue is with the LCD panel.

Press and hold the D key and turn on the computer to enter the LCD built-in self-test (BIST) mode. Continue to hold the D key until you see the entire screen change colors.

If you do not detect any screen abnormalities in the integrated self-test mode, the LCD panel of the laptop is functioning properly. Go to the Update the video card (GPU) driver, monitor driver, and BIOS section.

It is essential to verify if the problem is inherent with the monitor, video card (GPU) or video settings on your computer. A straightforward way to identify this is to connect the computer to a known-good external monitor or TV and ensure that the display cable (S-video, VGA, DVI, HDMI, DisplayPort, USB-C, or Thunderbolt 3) is firmly connected to the video port on the computer and the monitor.

If the issue persists on the other monitor it may be due to the video card (GPU) or video settings and not the monitor, go to the step Verify display or video issue in Windows Safe Mode. Else go to the next step.

Performance issues may occur if there is any type of damage that is caused to the display cables or the LCD screen. LCD screen may show that symptoms like LCD screen stops working, work intermittently, color mismatch, flickering, display horizontal or vertical lines if there is damage to the display cables or the LCD screen.

If you do notice a physical damage, contact Dell Technical Support to learn more about repair options that are available in your region. If there is no damage, go to the next step.

Dell monitors provide a self-test feature check (SFTC) and an integrated self-test (BIST) or integrated diagnostic (BID) tool that helps determine if the screen abnormality you are experiencing is an inherent problem with the Dell monitor or with the video card (GPU) and computer settings.

When you notice screen abnormalities like flickering, distortion, clarity issues, fuzzy or blurry image, horizontal or vertical lines, color fade, it is a good practice to isolate the monitor by running a diagnostic test on the Dell monitor.

To learn more about running a diagnostic test on your Dell monitor, see the Dell knowledge base article How to Run a Diagnostic Test on a Dell Monitor.

NOTE: Self-test feature check (SFTC) helps check if the Dell monitor is working normally as a stand-alone device. To check for screen abnormalities such as flickering, distortion, clarity issues, fuzzy or blurry image, horizontal or vertical lines, color fade, and so on, run the integrated self-test (BIST) or integrated diagnostic (BID) test.

NOTE: In certain Dell monitors, the integrated self-test (BIST) or integrated diagnostics (BID) can be run only when one or more video cables are unplugged and the Dell monitor is in self-test mode.

Dell monitors can be reset to factory default settings using the on-screen display (OSD) menu. This can be accessed using the buttons or joystick that is available on the Dell monitor. For step-by-step instructions to reset a Dell monitor to factory default settings, see the User Guide of your Dell monitor at the Dell Manuals website.

(Reuters) - Foxconn Technology Group is reconsidering plans to make advanced liquid crystal display panels at a $10 billion Wisconsin campus, and said it intends to hire mostly engineers and researchers rather than the manufacturing workforce the project originally promised.

Announced at a White House ceremony in 2017, the 20-million square foot campus marked the largest greenfield investment by a foreign-based company in U.S. history and was praised by President Donald Trump as proof of his ability to revive American manufacturing.

Foxconn, which received controversial state and local incentives for the project, initially planned to manufacture advanced large screen displays for TVs and other consumer and professional products at the facility, which is under construction. It later said it would build smaller LCD screens instead.

Now, those plans may be scaled back or even shelved, Louis Woo, special assistant to Foxconn Chief Executive Terry Gou, told Reuters. He said the company was still evaluating options for Wisconsin, but cited the steep cost of making advanced TV screens in the United States, where labor expenses are comparatively high.

When it comes to manufacturing advanced screens for TVs, he added: “If a certain size of display has more supply, whether from China or Japan or Taiwan, we have to change, too.”

Rather than a focus on LCD manufacturing, Foxconn wants to create a “technology hub” in Wisconsin that would largely consist of research facilities along with packaging and assembly operations, Woo said. It would also produce specialized tech products for industrial, healthcare, and professional applications, he added.

Earlier this month, Foxconn, a major supplier to Apple Inc., reiterated its intention to create 13,000 jobs in Wisconsin, but said it had slowed its pace of hiring. The company initially said it expected to employ about 5,200 people by the end of 2020; a company source said that figure now looks likely to be closer to 1,000 workers.

But Woo, in the interview, said about three-quarters of Foxconn’s eventual jobs will be in R&D and design - what he described as “knowledge” positions - rather than blue-collar manufacturing jobs. Foxconn is formally known as Hon Hai Precision Industry Co.\

Rather than manufacturing LCD panels in the United States, Woo said it would be more profitable to make them in greater China and Japan, ship them to Mexico for final assembly, and import the finished product to the United States.

He said that would represent a supply chain that fits with Foxconn’s current “fluid, good business model.”FILE PHOTO: A shovel and FoxConn logo are seen before the arrival of U.S. President Donald Trump as he participates in the Foxconn Technology Group groundbreaking ceremony for its LCD manufacturing campus, in Mount Pleasant, Wisconsin, U.S., June 28, 2018.

Heavily criticized in some quarters, the Foxconn project was championed by former Wisconsin Governor Scott Walker, a Republican who helped secure around $4 billion in tax breaks and other incentives before leaving office. Critics of the deal, including a number of Democrats, called it a corporate giveaway that would never result in the promised manufacturing jobs and posed serious environmental risks.

“Every step of the way Foxconn has overpromised and under-delivered,” Democrat Gordon Hintz, the minority party leader in the state assembly, said in a Wednesday statement. “This news is devastating for the taxpayers of Wisconsin.”

Foxconn CEO Gou plans to meet with Wisconsin’s new Democratic governor, Tony Evers, a past critic of the deal, later this year to discuss modifications of the agreement, according to the source familiar with the company’s thinking.

The Office of the Governor said in a Wednesday statement it has been in contact with senior leadership at Foxconn since the Reuters story was published. Evers’ aide Joel Brennan said the team was “surprised” by the development.
