lcd screen display problem factory

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.

There’re more than 300 procedures to produce TFT LCD. The most advanced LCD, in which the array and cell process are highly automatic. Technically, every step in the process can lead to defects, and most of the defects have been eliminated through the development of TFT LCD technology.

Point defect is a kind of defect that some point on your screen don’t display correctly. There are mainly three situations: the point keeps displaying black or whitewhen the screen is working or the point can only display a single color.

Usually, assembly of cell and IC is under heat and should be positioned accurately. Problems with IC connection will be checked out very soon, followed by the adjustment on machine parameter.

In LCD, newton’s rings may occur on screen when two glass substrate haven’t been sealed well, so that one of the glass may form a convex lens and lead to light interference.

To avoid this problem, we have to pay attention to the gap distance parameter in sealing process. By the way, newton’s rings has became a method to exam the glass sealing process in reverse .

The black matrix on CF glass or a additional shield bar is used to avoid this problem. So if this problem occurs, we have to check the CF deposition process.

You may notice there are some screens have uneven display, which means some white area appears in dark picture or vice versa. We call this ‘mura’, a word originated from Japanese.

Mura is very common but it doesn’t affect the screen function severely, however it still bring bad look. Hence, many high end display manufacturers have their own standards of mura, and the displays without mura are of the best quality.

Green Light: If the power is on, the connections are secure, the video signal source is on, and the light is still GREEN, then this dictates a problem internally with the monitor; it needs to be returned for repair.

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.

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.

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.

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.

My monitor is displaying a message saying “Sync Out of Range”If you are seeing this on your monitor, it means you are sending a video resolution to your monitor that is higher than your monitor’s native resolution.

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.

Just like televisions, laptop displays start to flicker too after a few years. You may sometimes also notice the display turning blank even when the laptop is on. Alternatively, you might find some white lines running down the display.

If you ever notice multi-coloured or single-coloured vertical lines on your laptop screen, it may be a result of a hardware failure or due to damage to the screen. To try fixing it yourself, first unplug your laptop, hold the power button for 30 seconds and restart the laptop. If you continue to see coloured lines, the issue is probably with the LCD screen, which will need to be replaced from the brand’s service center. To be sure about the LCD screen problem, try connecting your laptop to another monitor and see if the issue persists. If it does, the issue is certainly in the LCD panel.

On turning on the laptop when you see the lights blinking and hear the fan working but if the laptop screen is blank and doesn’t display anything, this is again an indication of a faulty motherboard. The first thing to do is to transfer all the data to another drive to make sure your data is safe. Before going ahead and getting the motherboard repaired or replaced, you could try performing a hard reset (also known as a factory reset), which can mostly help in resolving the blank display issue.

Firstly, check if your laptop’s brightness level is set to maximum. If the display is still dim, try restarting the device. This could just be a system error that can be resolved by restarting the device. Also, check if the AC adapter cord is loose and firmly connect it to the outlet and laptop. If the issue still persists, it is mostly due to a failure of the LCD. Behind the LCD, there is an inverter board and backlight bulb which control the picture.

The inverter board converts the low voltage your laptop uses, into higher voltage required by the long bulb that lights up the LCD screen. If the inverter board or bulb fail, you will experience the problem of a dimmed display. Even if one of these two components fail, the screen will need to be replaced, unless the service center can help by just replacing the bulb. We wouldn’t recommend you try resolving it yourself, as this is more complex and you could end up damaging the circuit board and the backlight lamp. So, it’s best to leave this job to an expert.

Laptops are fragile and can easily break, especially with more and more thinner and lighter models being launched now. Some of the most common ways how a laptop is damaged include: when it accidentally falls and the screen cracks, when it’s held at an awkward angle or if you unknowingly placed something heavy on the laptop. Remember, a cracked laptop screen can affect the overall functioning of the device in some cases.
