Answer
The Huawei Ascend Y540 screen module is known to have three key components: Glass Panel, Digitizer & Display. To know the differences between different type of parts available for Huawei Ascend Y540, we first need to know what is the function of each of these 3 components of the screen module.
* The Glass Panel or The Front Glass (Top Layer) - This is the top glass layer in the front, which you can touch and feel. Typically less than one millimeter thick, the glass panel does not have a functionality and mostly serves as a protective layer to the screen module.
* The Digitizer (Middle Layer) - A film like component, pasted just below the front glass. When you tap your fingertip or swipe it across the screen, the digitizer senses it and sends data to the phone processor. The digitizer pasted to the front glass together is called as a "Touch Screen".
* The Display or The LCD (Bottom Layer) - The bottom layer which produces the image. The display is the visual component underneath the glass that displays the image on the screen.
