LCD splicing screenIt is very common in the market. It is also divided into several categories. For example, DID, DLP, PDP, and OLED LCD splicing screens. It's very common now. DID and DLP introduce LCD splicing screens. The following answers typical LCD splicing performance.

1、 DID LCD splicing screen display principle

Firstly, the LCD panel is mainly composed of backlight and LCD glass; Secondly, the panel between LCD glasses consists of a liquid crystal layer, a filter layer, a conductive layer, and a protective layer. Finally, the light emitted by the backlight forms a uniform white light source through the lighting components, illuminating the LCD layer. After turning on the power of the LCD layer, the transparency changes with the current intensity, penetrating the LCD light layer through filters and glass, forming bright and dark colored pixels in the human eye, combined into a bright screen.

2、 DLP Display Principle

Firstly, the imaging part mainly consists of DMD chips and driving circuits; The optical part of DLP includes a light source part, an imaging part, and a display part; (LED or high-pressure mercury light bulb) lenses, refractors, lenses, etc; DLP light source focuses on optical equipment, which is used for color separation and refraction on the DMD chip. There are hundreds of thousands of micro mirrors on the DMD chip, which are controlled by the driving circuit to convert light rays. The changing light is amplified through the lens and projected onto the screen, forming a color image.

LCD splicing screenThere are several classifications of LCD splicing screens, and what are the differences; Reminder: There are four types of LCD splicing screens, some are common and some are rare. That's all for common types.
