Many netizens are easy to associate OLED displays with LED backlights that are currently being speculated by manufacturers. In fact, OLEDs and LED backlights are completely different display technologies. The OLED is driven by the current driving organic film itself, and the emitted light can be a single color such as red, green, blue, white, etc., and the full color effect can also be achieved. So OLED is a new lighting 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 displayed to display text, pictures, animations and videos. The content can be changed at any time, and all components are modular. Structured display device. Traditional LED displays typically consist of a display module, a control system, and a power system. The display module is composed of a dot matrix composed of LED lights, and is responsible for the light-emitting display; the control system can display the text, the picture, the video and the like by controlling the corresponding area to be turned off, and the monochrome and the two-color screen are mainly used for playing the text. The color LED display can not only play text, pictures, animations, but also video and other formats.
At present, it has been widely used in every corner of the world with its wide audience, simple operation, long service life and energy saving and environmental protection. In general, LED displays, LED backlights, and OLEDs are three completely different imaging technologies.
First, the OLED display. That 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, flexible panel, wide temperature range and so on. In the commercial field, OLED displays can be applied to POS machines and ATM machines, copiers, game consoles, etc.; in the field of communication, they can be applied to mobile phones, mobile network terminals, etc.; in the field of computers, they can be widely used in PDAs, commercial PCs and homes. On PCs and laptops; 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 and aircraft instruments.
Second, LED display devices. LED series products are all backlit LCD screens. The LED liquid crystal screen can adjust the brightness of the corresponding position of the LED according to the brightness of the image and the surrounding color, so that the contrast of the area will be dynamically converted according to the requirements of the picture, so that the contrast of each display part of the entire LCD screen is not the same. The viewing effect will be much better. LED series products have been widely loved by consumers because of their beautiful appearance and ultra-thin size. LED light-emitting diodes are solid-type electronic lighting, which has higher resistance to heavy impact than CCFL. LED light-emitting diodes are not as environmentally friendly as UV-LED lamps, and are more environmentally friendly. Therefore, LED screens are lighter. Ultra-thin size; LED LCD screen color saturation is better.
