There are many reasons an LCD may rejected. Sometimes the screen itself is badly damaged, sometimes it’s a minor issue that significantly devalues the screen and sometimes the issue is more internal, such as a bad cable. Below you will find a detailed guide to what common problems can occur and result in a rejected screen.

Cracks – Cracks in the screen are fairly common, and vary in size and shape. Sometimes you will see a crack across the entire screen, other times it may be very small and/or hard to spot. A variety of other effects can be caused by these cracks such as lines in the display or the liquid crystal (which looks like a black ooze) leaking from the cracks.

Blemishes – A variety of things can be considering a blemish on the screen. White spots caused by water damage, scratches or other physical marks on the LCD often caused by tools or adhesives yellow or orange marks can be rejected depending on their severity. Colored smudges can also occur due to several reasons and are generally rejected. These smudges can vary in size, shape and brightness and appear in a multitude of colors such as red, pink, blue, yellow or purple. It is not uncommon for multiple colors to appear in these smudges.

Pixels – We reject any screen screens with dead or frozen pixels. Pixels can appear anywhere on the LCD in several different colors. They can sometimes be not so obvious, but if a tester spots a dead pixel the screen will be rejected regardless of the pixel’s size or color.

Pinpoints – “Pinpoints” are smaller, shimmery pixel defects. They appear white or iridescent, can vary in size and often appear and disappear depending on the viewing angle. A single tiny pinpoint may still pass as a good LCD, however, a much brighter pinpoint or multiple pinpoints may result in a lower grade or rejected LCD.

Red Shadows – A not so uncommon issue with iPhone LCDs, particularly third party LCDs, are red shadows, also known as “pink pills”. These appear on a white screen and look like a pink or purple rectangle in the center of the screen. Red shadows can vary in size and brightness and will result in a lower graded screen.

Bad Digitizers – Occasionally an LCD may appear undamaged but have internal issues that result in rejection. Usually these issues are either in the form of lines and/or blocks on the screen or the LCD touch may not be functioning properly. Depending on the assessment of our experienced testers, these issues may be considering minor or temporary and can result in lowering the grade or outright rejection.

Dim Display – Sometimes an LCD will have a functioning display and touch, but will appear darker or dimmer than it should. This will result in rejection or lowering of grade.

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.

Unlike older cathode ray tube (CRT) displays that scan an electron beam over a phosphor screen to create light, LCD displays are composed of a fixed grid of tricolor pixels that change transparency based on a range of voltage levels provided by the monitor"s controller. Without a voltage the pixel is opaque and blocks the screen"s backlight from transferring through it, and when a full voltage is applied then the pixel allows full transmittance of the backlight. When this is done over the entire pixel grid in patterns, then you see those patterns on the screen.

At a very basic level, the way pixels work is a voltage change alters the pixel to allow more or less light through. When there is no voltage, no light is let through (darker), and when the voltage is at its maximum level then 100 percent of the light is allowed to pass through (brighter). By supplying intermediate voltages the computer adjusts the pixel"s transmittance levels for its three color components, to display various combined colors and intensities.

This pixel-based setup for LCD monitors provides many advantages over CRT displays, but does have potential drawbacks arising from the fact that the image is dependent on millions of independent electrical components as opposed to a single scanning beam, so if faults occur in these components then the display output can be affected. The resulting problems include stuck or dead pixels, as well as a residual image effect.

One of the more common problems with LCD displays is the potential for stuck or broken pixels, where the pixel either does not receive a voltage and remains black, or does not respond to voltage changes and stays at a set luminance level. Sometimes this can happen for individual pixels, suggesting a problem with the pixel itself, or it can happen to groups of pixels, suggesting the possibility of problems with the display"s controller or a defect in a portion of the pixel grid.

When stuck or broken pixels occur, there are a couple of things you can try in order to fix the problem. One is to apply a small amount of pressure to the pixel when turning the display on or off, which can sometimes help stimulate the electronics to work properly. Unfortunately, Apple"s glass-covered glossy displays prevent this from working on modern Mac systems.

The alternative to using pressure is to exercise the pixel"s electronics by using a program that displays quick-changing patterns on the screen and thereby rapidly switches the pixels on and off. Three such programs that will work on the Mac are the following:

LCD monitors can also be affected by another problem called "transient persistence" that is reminiscent of CRT burn-in. Classic burn-in would happen because the phosphor coating on the screen would get depleted by the persistent bombardment of electrons from the CRT, resulting in the inability of those sections of the display to convert the electron beam to visible light. This meant that if you kept a specific pattern showing on the screen then over time it could become a permanent residual image on the display that would show even when the display was turned off. This was a reason why screensavers were developed--to keep the wear on the screen"s phosphor coating as even as possible.

The physical burn-in of displays is no longer an issue now that LCD displays have taken over, but while transient image persistence is not a physical burn of the device, it is an alteration of the pixel response to voltage changes (usually temporary) that prevents pixels from getting as bright as others on the screen.

Similar to CRT burn-in, LCD image persistence generally happens after you have displayed a pattern of intense colors on screen; however, unlike CRT burn-in, LCD persistence can sometimes set in after only a few hours of displaying the image, as opposed to the weeks or even months that it can take for burn to set in on a CRT monitor. Additionally, unlike CRT burn-in, image persistence can often be reversed.

What happens with LCD monitors is the affected pixels have lost their ability to respond to the full range of voltages that the display gives them, resulting in a limited range of colors that can be output. This can happen if the pixel is acting like a capacitor and is retaining a residual charge, or if it is not able to reach the level of luminance that is desired when given a specific voltage. Either way, the pixel is not able to reach its full range of possible intensities.

Unlike stuck or dead pixels that may benefit from having the monitor turned on and off rapidly to produce rapid voltage changes, image persistence will benefit from a lengthy stretching of the pixel"s range. Therefore, instead of using tools like JScreenFix to run random patterns over the affected screen area, you might instead place a pure white window (such as an empty TextEdit window, or what you get using the "White" option in the LCD Repair tool listed above) over the affected area for a few hours or even a few days if necessary. Doing this will force those pixels to be fully on, and over time their intensities may increase to be the same as the surrounding pixels.

Likewise, try turning off the pixels fully by shutting down the display for a long period of time or placing a pure black texture over the affected area (see the LCD Repair tool listed above for this option as well). This will turn the pixels completely off and allow residual voltage in them to drain slowly over time.

So far we have discussed pixel-based problems with LCD displays, but the system"s backlight can also suffer some common problems that include the backlight randomly blinking off, not turning on, or only illuminating part of the screen.

When the display fully cuts out and does not show any light, one possibility could be that your computer is not properly communicating with the display, or the display"s controllers or power supply are not working properly. If this occurs, try connecting the display to another system. But if power LEDs and other indicator lights turn off when the backlight goes out, then it may be your display"s power supply is failing.

If only the backlight is malfunctioning, then the LCD panel itself should still be working just fine and should be rendering the text and images of your computer"s output. To test for this, use a bright flashlight and shine it on your screen at an angle in an area where you expect images and text to be (such as the Dock or menu bar). On Apple"s laptop systems, you can shine the flashlight through the Apple logo on the back to illuminate the screen on the front and better detect text and images that way.

If shining an alternative light source on the display causes graphical content to show up, then either the backlight or some component involved in controlling it (such as the power inverter for it) have failed and will likely need to be replaced, especially if you cannot rectify the problem by restarting the system, resetting PRAM and SMC, or otherwise toggling different hardware and software settings on your system.

Apple has determined that a small percentage of iPhone 11 displays may stop responding to touch due to an issue with the display module. Affected devices were manufactured between November 2019 and May 2020.
