Liquid crystals (LCDs) control brightness by distorting the light transmitted through voltage. Neither liquid crystals nor light are inherently colorless; color is created by adding a green film.
Because it's controlled by voltage, it's definitely analog. This is from the perspective of how liquid crystals work. After being processed into an LCD screen, liquid crystals are classified as analog or digital depending on the leads connected.
Therefore, the distinction is based on whether the signal input to the LCD panel is digital or analog. Furthermore, analog screens can directly receive signals, while digital screens require a driver board. Front cover?
All mobile phone screens consist of two main parts: the outer screen and the inner screen. The inner screen is the display (LCD/AMOLED screen, etc.), and the outer screen protects the inner screen.
The outer screen can be a touchscreen or a non-touchscreen. A non-touchscreen outer screen is a layer of acrylic plastic or glass, installed directly above the inner screen to protect the fragile display.
In touch-enabled machines, the outer screen not only maintains the inner screen but also collects touch coordinate data. Touchscreens have a much more complex structure than non-touchscreens, but they look similar. The body of a touchscreen is a semi-transparent thin sheet. Some touchscreens and displays are packaged together as one unit, integrating touch and display functions. Therefore, what is commonly referred to as a touchscreen is actually a touchscreen screen. However, in reality, a touchscreen is an independent component.
