The Difference Between Glass, Digitizer, Touch Screen and LCD

Leave a comment

Your iPod, iPhone and tablet are commonly known to have three key components: a glass panel, digitizer (aka touch screen) and LCD. What are the differences? Let’s clearly define these layers:

  • Layer #1: Glass panel – the topmost layer
  • Layer #2: Digitizer (also known as touch screen) – just under the glass and fused with it
  • Layer #3: LCD – located under the digitizer

Glass – The outermost layer is the glass, typically less than one millimeter thick. If you drop your device, the cracked glass ends up resembling an elaborate spiderweb.

Digitizer – The digitizer is located just under the glass screen. It is the electrical force that senses and responds to touch. When you tap your fingertip or swipe it across the screen, the mere touch acts as data input to the device’s center. If your device fails to respond to touch, it’s time for a new digitizer. The digitizer is an electrical mechanism that is fused with the glass screen; so if you need to replace the digitizer, you’ll have to replace the glass, too, and vice versa. UEG offers a Front Glass (Digitizer Touch Screen) Repair Service on tablets.

Touch Screen –  The term touch screen is interchangeable with the term digitizer. You’ll often see the combined terms Digitizer Touch Screen offered as a repair service.

LCD – LCD is an acronym for liquid crystal display. The LCD is the visual component underneath the glass that displays the image on the screen. UEG offers LCD repairs on tablets, iPhones and iPods.
