The LCD panel is the core component of the LCD display, also known as the LCD module (LCD module). It is a planar structure composed of liquid crystal material, glass substrate, electrodes and other key components. Liquid crystal material is a key element located in the LCD panel. Liquid crystal molecules can change their orientation according to the action of an external electric field to control the degree of light transmission. LCD panels are usually made of two glass substrates (called glass substrates) sandwiching a liquid crystal material between the two glass substrates. The glass substrate is the basic structure of the LCD panel, which has sufficient transparency and flatness to ensure the clarity and accuracy of the image on the display. The glass substrate is covered with transparent electrodes, which are used to apply an electric field to the liquid crystal material to control the orientation of the liquid crystal molecules. The LCD panel also includes other key components, such as polar plates, color filters, backlight, etc., to achieve color reproduction and display functions. The liquid crystal panel is the core technology of the liquid crystal display. By adjusting the orientation of the liquid crystal molecules through the electric field on the liquid crystal panel, the degree of light transmission can be controlled, and finally images or characters can be presented. According to different application requirements, LCD panels can be manufactured into LCD displays of various sizes, resolutions and functions.
