Sreen Repair

 

If something has been dropped on your laptop or your laptop itself is dropped on a hard surface, the LCD or LED screen may become cracked. Fortunately, this is a simple replacement that can be handled quickly and efficiently by our engineers, so you can resume use of your laptop.

Laptops use one of two types of screen, LED (Light Emitting Diode) or LCD (Liquid Crystal Display) compared to traditional desktop monitors which use CRT (Cathode Ray Tube). There are three different types of LCD screens: transmissive, transflective and reflective. Other differences in laptop screens to check for are whether the screen is widescreen or as stated above LED.

Transmissive Screens

Transmissive LCDs are the most commonly used LCD screens because they are high quality at a low price. The screen uses a thin film transistor that allows current to pass through it and light up the diodes. Transmissive displays provide excellent viewing indoors, the downside to transmissive LCD screens is that the backlight can be overpowered by bright lights or direct sunlight during outdoor use making viewing difficult, if not impossible.

Reflective Screens

Reflective screens use the same technology that transmissive screens use, except that they do not have the same backlighting of the transmissive screens. A reflective LCD uses the ambient light in the vicinity. The light passes through the LCD layer to a mirror, which reflects it back to the viewer. Reflective LCDs are the least costly, but require bright light. Viewing is difficult in dark rooms or outside at night. Reflective LCDs can also be built with frontlights, which significantly improve the viewing in dimly lit environments.

Transflective Screens

Transflective screens are a hybrid of the transmissive screen and the reflective screen technologies that allows the LCD to act like a transmissive screen indoors and a reflective screen outdoors, effectively using a backlight as does transmissive, but also adding a reflective mirror that lets light pass through from the back. The downside to transflective screens is the increased cost of production and because the mirror is built to let through backlight as well as reflect frontlight, it cannot do both equally as well as mirrors dedicated to one purpose. As a result, transflective LCDs are typically not quite as bright indoors as transmissive units and not as bright outdoors as reflective ones.

Widescreen displays have a width that is 1.6 times its height, unlike the traditional full screens that have a width 1.33 times its height. They are commonly used for widescreen films and media because the aspect ratio better reflects the natural field of view.

LED displays

Laptop screens are starting to use LED lights for backlighting of the screen. The LED lights use less power, so the battery will last longer. Screens with backlit LED displays are also thinner than traditional screens due to the lack of needing an inverter to power the screens backlight. However, LED screens are much more expensive.
