A leading edge technological facility with cleanrooms and industrial filtration systems is required to create a modern working LCD.Ĭurrently some touchscreens can be replaced separately from the LCD module – but even those are slowly becoming thinner and more sophisticated – some LCD modules already include the touch-screen in its construction – and in those cases the touchscreens can only be replaced together with the LCD. Because there are just so many little connections required to enable an LCD panel to work at all, it is also why there are virtually no fake or counterfeit laptop screens. Unfortunately, even if the glass was to be superglued back together and the liquid crystal solution refilled, the thousands of transistors along the crack have been irreparably severed ( 1080p display has 2,073,600 pixels and 6,220,800 sub-pixel transistors) – stitching those together is akin to neural surgery. The liquid crystal containment vessel is broken, and those black splotches of ink that characterize a physically damaged LCD begin spreading through the cracks and leaking outside of the glass substates. By mixing the intensity and combination of these basic colors each pixel is able to display up to 16.5 million colors individually.īut what happens when the screen is cracked? The light passes from the back-light though the sub-pixel onto a color filter showing one of the three basic colors: Red, Green or Blue. Each pixel is chemically printed on each of the two glass planes, and each LCD pixel has three transistors in it called sub-pixels which turn transparent (reorient themselves sort of like window blinds) when an electrical current is applied. At the core of the LCD Matrix there are two glass substrates that form a sealed vessel for the solution of liquid crystals which form the image. This brings us to the most commonly broken part of a laptop screen – the LCD Matrix. Only several years ago replacing a CCFL bulb was in some cases an acceptable way to save money to fix a 5 year old dim LCD, but with the mass adoption of LED back-lit displays and a gradual phase-out of the traditional CCFL bulbs, a modern LED back-light almost never fails.
