Many netizens easily associate OLEDs with LED backlights that are currently hyped by manufacturers. In fact, OLEDs and LED backlights are completely different display technologies. The OLED emits light by driving the organic thin film by electric current. The light emitted can be monochromatic colors such as red, green, blue, and white, and can also achieve the effect of full color. So OLED is a new light emitting principle different from CRT, LED and liquid crystal technology.

The LED display is composed of LED dot matrix and LEDPC panel. The red, blue, white, and green LED lights are on and off to display text, pictures, animations, and videos. The content can be replaced at any time. Each component is modular. Structured display device. Traditional LED display usually consists of display module, control system and power system. The display module is composed of a dot matrix composed of LED lights, which is responsible for light-emitting display; the control system can control the display of text, pictures, videos and other content by controlling the on and off of the corresponding area. The color LED display can not only play text, pictures, animations, but also video and other formats.

At present, with its wide audience, simple operation, long service life and energy saving and environmental protection, it is widely used in every corner of the world today. In general, LED displays, LED backlights, and OLEDs are three completely different imaging technologies.

First, OLED display. This is an organic light emitting diode (OLED) display. OLED has the advantages of simple structure, self-lighting without backlight, high contrast, thin thickness, wide viewing angle, fast response speed, can be used for flexible panels, wide temperature range and so on. In the commercial field, OLED displays can be applied to POS and ATM machines, copiers, game consoles, etc .; in the communication field, it can be applied to mobile phones, mobile network terminals, and other fields; in the computer field, it can be widely used in PDAs, business PCs, and homes. PC, notebook computer; in the field of consumer electronics, it is suitable for audio equipment, digital cameras, portable DVDs; in industrial applications, it is suitable for instruments, etc .; in the field of transportation, it is used for GPS, aircraft instruments, etc.

Second, LED LCD screen. LED series products are backlight LCD screens. The LED LCD screen can dynamically adjust the brightness of the LED at its corresponding position according to the lightness and darkness of the image and the surrounding colors. As a result, the contrast of this area will be dynamically converted according to the requirements of the screen, making the contrast of each display part of the entire LCD screen different. The viewing effect will be much better. LED series products are widely loved by consumers for their beautiful appearance and ultra-thin size. LED light-emitting diodes are solid-state electronic lighting, and their resistance to heavy impact is higher than CCFL. LED light-emitting diodes are not as environmentally friendly as CCFL lamps, and they are more environmentally friendly. They are more environmentally friendly. LED LCD screens are lighter. Ultra-thin size; LED LCD screen has better color saturation.
