What is the difference between touch digitizer and LCD screen?
The touch digitizer and LCD (Liquid Crystal Display) screen are two distinct components of a touch screen device, such as a smartphone or tablet. Here's a brief explanation of each:
LCD Screen (Display):
The LCD screen is responsible for displaying the visual content on your device.It consists of layers of glass with liquid crystals between them. These crystals react to electrical currents to produce images on the screen.
The LCD screen is the primary component that shows text, images, videos, and other graphical content.
Touch Digitizer:
The touch digitizer, often referred to as the "touch screen" or simply "digitizer," is a separate layer above the LCD screen.Its main function is to sense and respond to touch input. When you touch the screen, the digitizer detects the location and translates it into digital signals that the device can understand.
There are different types of touch digitizers, such as resistive and capacitive. Most modern devices use capacitive touch screens, which are more responsive and support multi-touch gestures.
In summary, while the LCD screen is responsible for displaying visual content, the touch digitizer is responsible for detecting touch input. They work together to provide the user with a responsive and interactive experience on touch screen devices. If either the LCD or the digitizer is damaged, it can affect the overall functionality of the touch screen.
