Definition of LCD, LED, OLED three display screens?

LED display (LED display) is a flat-panel display, which is composed of small LED module panels, and is used to display various information such as text, images, videos, and video signals.

An OLED display is a display made of organic light-emitting diodes. Since it also has self-luminous organic electroluminescent diodes, no backlight is required, high contrast, thin thickness, wide viewing angle, fast response speed, can be used for flexible panels, wide operating temperature range, simple structure and manufacturing process, etc. , is considered to be the next-generation flat-panel display emerging application technology.

The prospect of China's OLED industry is very broad, and companies in the industry are also working hard to accumulate development experience. However, factors such as weak upstream links in the domestic industrial chain and lack of supporting capabilities in the industry have created relatively large development obstacles for the majority of manufacturers.

LCD display, also known as liquid crystal display, is a flat and ultra-thin display device, which consists of a certain number of color or black and white pixels, placed in front of the light source or reflective surface. Liquid crystal displays consume very little power, making them favored by engineers for electronic devices that run on batteries. Its main principle is to stimulate liquid crystal molecules with current to generate points, lines, and surfaces to form a picture with the back lamp tube.
