Common LCD screen display problems

A problem with the LCD screen display can occur for a variety of reasons, including:

1. The LCD screen is white

If an LCD does have a white screen, it implies the backlight is working properly. Simply examine your signal input channels to determine the most likely causes.

It may also be affected by the display being completely disrupted by excessive heat, a shock that breaks the LCD controller, or a connection failure that requires professional repair.

2. Images are blurred

Since LCD graphics are made up of RGB pixels, their display should not be as blurry as it was on old CRT displays. If you see blurry images, there are two possibilities;

§ LCD has a response time; if you're playing a game or watching a fast-paced movie, some old LCD screens may have image delays.

§ The LCD's surface is composed of a plastic film layer with maximum hardness. If you happen to clean the surface frequently or use the incorrect detergent or solvent, you will cause surface damage.

To repair a damaged LED screen, it must be replaced by a professional.

3. The impact of environmental factors on LCD assembly (moisture, cyclic loading and temperature).

4. The impact of handling situations on the LCD (frequent shock, bending, and drop conditions).

5. The impact of the manufacturing process.

This type of defect is becoming rare as LCD technology has advanced over the years, thanks to modern manufacturing equipment.

Others include a decline in screen or display contrast, broken glass, non-functioning pixel resolution or the entire display. Different types of LCD problems require different types of repair methods.

How to repair an LCD display problem?

1. Shattered glass

If you drop the LCD and discover it got broken on the surface but the display still works, you may have simply damaged the touch panel; you could replace it by finding a repair shop.

If the display does not appear, especially if fluid is leaking out, you must repair all of the display modules.

2. The LCD screen is dim

Backlight is used because LCD cannot emit light on its own. Usually, the backlight isn't entirely driven; however, you can intensify the backlight to brighten a dim LCD screen.

However, if it has been in operation for a significant period, it is entirely feasible that the LED backlight must have reached its end of life if the backlight brightness is set to 100%.

To repair an LCD screen, you must first devise a way to fix the backlight. It is a simple task for some displays, although it can be challenging for others based on the process of manufacturing.

3. Image adhesion

Happens if you switch to another image but the previous image is still visible in the background. Professionals are not required to repair this type of failure.

Simply turning off the display for a day will solve the problem.
