Here at Mobile Screen Fix we see all types of phone screen damage ranging from shattered, dead pixels, water damage and broken LCDs. In this article we want to discuss the different types to help you identify the difference between them and any possible solutions to get you up and running as quickly as possible.
To help you understand, you should know what the screens are made of. Smartphone screens are made up of two thin layers; a glass screen and a Liquid Crystal Display (LCD) screen with an incorporated digitizer. The glass screen is responsible for protecting. The LCD screen is important for quality display and touch-response.
This is the most common type of damage and equally the hardest to explain. This is where only the glass is smashed and the LCD behind is still fully operational with no dead pixels, backlight issues or touch sensitivity issues. Now the glass itself isn’t expensive however the expertise in removing the old one without compromising the LCD beneath isn’t easy and requires a high level of experience. At Mobile Screen Fix although this is something we are capable of doing it takes time and that’s time being charged to you and ultimately we still can not guarantee the LCD won’t fail after a month, after all the phone has been dropped? This is something we don’t offer and instead when facing this issue we simply will replace the glass and LCD in one fitting.
Dead pixels on Phone
This particular type of condition ranges from white small dots to larger black dots. LCD screens are made up with million pixels, a dead pixel occurs when the transistor that activates the amount of light that shows through all three subpixels malfunctions and results in a permanently black pixel.
The good news is if you’re happy to ignore it, in our experience it’s unlikely to get worse. However if its something that’s driving you mad it will come at the cost of a whole new LCD, which in tern as discussed above will result in the new glass too.
Backlight leakage problem
Backlight bleeding or leakage as it’s sometimes referred to is when light from the cold cathode fluorescent tubes (CCFT) finds its way around the display panel in the LCD when it has not been adhered sufficiently. This is discussed in more detail here Phone Screen Bleeding. Over time this can worsen and with any faulty Phone LCD screen this would require a new LCD.
By now you are probably starting to see a pattern. Anything involving a defective LCD is going to hit your pocket hard and in the case of an unresponsive touch/digitizer this is no different. As the digitizers are built into the phone LCD screen it’s almost certain it’s going to require a new LCD all together.
The very last type of screen damage is a pressure spot. Something that is quite trivial for some users but can differ in severity. Pressure spots are caused by the application of extreme pressure on the screen which leads to the rupturing of the LCD screen, it can happen during the refurbished process, or phone drops and hits hard surface. Again if you can live with this id recommend it as the only other solution a new LCD.
