Do you know the difference between LCD and LCD Digitizer?

Well, to put it a simple way LCD stands for Liquid Crystal Display, is the component that actually “displays” The LCD is usually very thin, and extremely fragile. Digitizer stands for the glass on the front of your screen.As for LCD Digitizer it contains LCD and Digitizer.

Let’s see the picture first

The picture to the top is the iPhone LCD replacement part, removed from the LCD Digitizer. This LCD is what is responsible for actually displaying the image. This part is extremely FRAGILE and can break very easily. The cable at the top of the LCD is the LCD flex cable, this is directly attached to the LCD and is what connects to the iPhone’s logic board during installation. If the LCD flex cable is not seated properly or torn during installation, it can cause several different issues such as a black screen, lines going up an down, faded images, discoloration, flickering of the LCD, etc.

 

The Digitizer is a completely separate component than the LCD. So the glass on the front of your screen is the Digitizer, it is essentially the front glass that cover the LCD. The digitizer’s main function is to protect the fragile LCD, as well as to transfer all of the touch functions (swipe, press, zoom, etc) to the LCD. The touch action on the Digitizer glass is transferred through the Digitizer flex cable, so the LCD image can respond accordingly. The Digitizer flex cable should already come installed on the glass digitizer (You can see the flex cable at the top of the Glass Digitizer in the picture below)

Below is a picture of the iPad Digitizer Glass:

As you can see, this part (Digitizer) is separate from the LCD.

 

This is where things can get confusing- an LCD Digitizer assembly is actually these two parts fused together. If the glass digitizer is broken, some people say you can change the glass itself by separating it from the LCD. The best way to repair a broken LCD or Digitizer is to go to repair shop. Because it is literally nearly impossible unless you have the right tools. And even when you have the right tools, you run the risk of scratching and compromising the LCD of the device.
