Many netizens are easy to associate OLED displays with LED backlights that manufacturers hype more, in fact, OLED and LED backlights are completely different display technologies. OLED is emitted by driving the organic film itself by current, and the light emitted can be red, green, blue, white and other monochromes, which can also achieve a full-color effect. 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, through the red, blue, white, green LED lights to display text, pictures, animation, video, content can be replaced at any time, each part of the components are modular structure of the display device. Traditional LED display usually consists of display module, control system and power supply system. The display module is composed of a dot matrix composed of LED lights, which is responsible for illuminating the display; The control system by controlling the light and extinguishment of the corresponding area, can make the screen display text, pictures, videos and other content, monochrome, two-color screen is mainly used to play text, full-color LED display can not only play text, pictures, animation, but also play video and other formats.
At present, it is widely used in all corners of the world today with its advantages of wide audience area, simple operation, long service life, energy saving and environmental protection. In general, LED display, LED backlight, OLED 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-illumination without backlight, high contrast, thin thickness, wide viewing angle, fast response speed, can be used for flexible panels, and has a wide temperature range. In the commercial field, OLED displays can be applied to POS and ATM machines, copiers, game consoles, etc.; In the field of communication, it can be applied to mobile phones, mobile network terminals and other fields; In the field of computers, it can be widely used in PDAs, commercial PCs, home PCs, and notebook computers; In the field of consumer electronics, it can be applied to audio equipment, digital cameras, portable DVDs; In industrial applications, it is suitable for instrumentation; In the field of transportation, it is used in GPS, aircraft instruments, etc.
Second, LED display. LED series products are backlit LCD screens. The LED LCD screen can dynamically adjust the brightness of the LED in its corresponding position according to the brightness of the image and the surrounding color, resulting in dynamic conversion of the contrast of the area according to the requirements of the picture, so that the contrast of each display part of the entire LCD screen is not the same, and the viewing effect will be much better. LED series products have been widely loved by consumers for their beautiful appearance and ultra-thin size. LED light-emitting diodes belong to solid-state electronic lighting, and their resistance to heavy impact is higher than that of CCFL; LED light-emitting diodes are not as environmentally friendly as CCFL lamps and UV leakage concerns, so they are more environmentally friendly; LED LCD screen light and ultra-thin size; LED LCD screen color saturation is better.
