LED/LCD SCREEN CARE (Light Emitting Diode/Liquid Crystal Display)
LED/LCD screen panels of a laptop are made of extremely thin glass making them one of the most fragile and expensive components. All parts relating to LED/LCD screen panels can easily be damaged due to ageing which results in a high fault rate.
Heavy usage of the screen will cause colour deviation and the image to appear dim on the display and the areas near the backlight may become red in colour. Instability in the power supply to the screen from the LCD inverter will directly affect the quality of the display.
Dead and Stuck Pixels
A “Dead Pixel” is a defective pixel that remains unlit. Dead pixels are usually best detected against a clear white background where it will appear as a red, green, blue, cyan, magenta or yellow dot, although red, green or blue pixels are the most common.
A “Stuck Pixel” results from a manufacturing defect which will leave one or more of these sub-pixels to remain permanently on or off. This issue arises most often due to ageing or poor quality LCD screens. It is important to be aware that images can become “burned” into an LCD screen if left displayed for an extended or considerable period of time without use or a screen saver which can cause “Dead” or “Stuck” pixels.
LCDs are very easily damaged due to many varying human factors. Cracks in an LCD screen will cause pixels to display abnormally, which is most commonly caused by severe impact or pressure on the screen itself. LCD screens are extremely delicate, fragile devices and as such need to be handled with the utmost care
Pressure on LCD screens
Never place anything heavy on the back of an LCD screen and never press too hard on the LCD screen otherwise permanent damage may be caused to the pixels in the affected area as the screen’s surface is not designed to be touched.
Never expose LCD screen panels to direct sunlight or excessive heat will damage your screen irreparably. Always ensure that LCD screen panels are kept in a cool, dry and well ventilated area. Also never use the LCD screen in snow or sub-zero temperatures which can also cause permanent damage to the pixels.
Always make sure that the laptop is correctly switched off with the battery removed and the AC adaptor unplugged before cleaning your screen. Never use alcohol, detergents or even mild soap to clean your screen and never spray or pour any liquid directly onto the screen. Be sure to use a very soft, micro-fiber cloth that is non-abrasive, 100% cotton, lint free and slightly damp with a little distilled water and gently wipe the screen, it is even more effective to use a small amount of spirit vinegar when cleaning your LCD screen.

It can be very difficult to detect a tiny “Dead” or “Stuck” pixel on the screen panel with the naked eye, however, using specialised software, DPT 2.30C, will help you in finding them. This software performs a series of tests in black, white, red, green, blue, yellow and grey up to 16 colours making it easier for the user to easily identify any “Dead” or “Stuck” pixels that may be present on the screen.
When a “Dead” or “Stuck” pixel is found, the user can attempt to restore the pixel(s) by using an online service called JSCREENFIX. Basically, it performs a series of rapid and repeat resonance actions to stimulate and try to recover from the “Dead” or “Stuck” pixel(s), although there is no guarantee of recovery, it is definitely worth a try as it is a free service.
