Which OLED display screen manufacturer is more professional?
Brands that are big are generally good. In general, LED display, LED backlight, OLED are three completely different imaging technologies. LED backlight refers to the use of LED (light-emitting diode) as the backlight of the liquid crystal display, and the LED backlight display is only the backlight of the liquid crystal display from the traditional CCFL cold light tube (similar to fluorescent lamp) to the LED (light-emitting diode).
The imaging principle of liquid crystal can be simply understood as that the external voltage is applied to deflect the liquid crystal molecules, which blocks the transparency of the light emitted by the backlight like a gate, and then projects the light into color filters of different colors to form an image. The transition of the backlight module from CCFL to LED can bring many benefits, which can make the brightness of the display screen more uniform, the product power consumption is lower, and the shape can be lighter and more fashionable.
However, the current market is generally used W-LED (white LED) backlight, in fact, this backlight only replaces the light-emitting components, and the display effect is very weak or even not improved. The RGB-LED (three-color LED) that significantly improves the display effect of LCD products has a more obvious improvement in the display effect, but at the same time the production cost is higher, so it is used in high-priced LCD TVs. At present, the LED display mentioned by the business refers to the display products using white LED backlight, and the difference between ordinary LCD display is the change of backlight. OLED is the abbreviation of English OrganicLight-EmittingDiode, which translates to organic light-emitting diode or organic light-emitting display.
In fact, this light-emitting principle was discovered as early as 1936, but it was not until Kodak launched OLED double-layer devices in 1987 that OLED attracted attention as a commercially available and high-performance flat panel display technology. OLED display is considered to be the next generation of emerging application technology of flat panel displays due to its excellent characteristics such as self-illumination, no backlight, high contrast, thin thickness, wide viewing angle, fast response speed, can be used for flexible panels, wide temperature range, and simple structure and process. Many people are easy to associate OLED with the LED backlight that LED display manufacturers hype more, in fact, OLED and LED backlight 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.
