When it comes to a damaged LCD screen, the only solution is to replace it entirely. No matter the severity of the damage, attempting to fix a cracked LCD panel is not a viable option. The intricate structure of an LCD screen makes it impossible to repair without replacing the entire unit.
Understanding LCD Screen Anatomy
An LCD screen consists of several layers, including a back-light assembly, LCD matrix, and additional layers for glossy effects or reflection diffusion. Some screens may also include a touchscreen layer on top. The LCD matrix is the core component, containing two glass substrates that form a sealed vessel for liquid crystals. Each pixel is chemically printed on the glass planes, with three transistors called sub-pixels that turn transparent when an electrical current is applied. This process allows the light from the back-light to pass through the sub-pixels, creating the image on the screen.
Why Cracked LCD Panels Can’t Be Fixed
When an LCD screen is cracked, the liquid crystal containment vessel is broken. This damage causes the black splotches and leakage that characterize a physically damaged LCD. The liquid crystals begin to spread through the cracks and leak outside of the glass substrates, making it impossible to repair the screen without replacing the entire LCD matrix.
While it may be possible to fix certain issues, such as a loose cable or a faulty electrical connection, a cracked LCD panel cannot be repaired. The only solution is to replace the entire screen assembly, which includes a new LCD with touch glass attached, if applicable.
