What is the difference between LCD display, OLED display and LED display?

1. On the color gamutOLED displays can display endless colors, and are not affected by the backlight. Pixels are very advantageous when displaying a completely black screen. Currently, the color gamut of LCD displays is between 72% and 92%. , while the color gamut of the LED display is above 118%.2. In terms of priceLED displays of the same size are more than twice as expensive as LCD displays, and OLED displays are even more expensive.3. In terms of technology maturityBecause LCD display is a traditional display, it is much better than OLED and LED in terms of technology maturity, such as display response speed, OLED and LED are far behind LCD displays.4. In terms of the angle of the displayOLED displays are much better than LED displays and LCD displays. The specific performance is that the viewing angle of LCD displays is very small, while LED displays are unsatisfactory in terms of layering and dynamic performance. In addition, the sense of depth of LED displays is not good enough. With the development of technology, liquid crystal technology is also constantly improving, and people's demand for various displays is also constantly increasing. Perhaps in the future, liquid crystal technology will develop to a new height, and there may be a new kind of display that can replace liquid crystal technology. new technology.

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.
