Brands are generally good. In general, LED displays, LED backlights, and OLEDs 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, while the LED-backlit display only the backlight of the liquid crystal display is over-extended to the LED (light-emitting diode) by a conventional CCFL cold-light tube (like a fluorescent lamp).
The imaging principle of liquid crystal can be simply understood as that the external voltage is applied to deflect the liquid crystal molecules to block the transparency of the light emitted by the backlight, and then the light is projected into the 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 power consumption of the product is lower, and the shape can be thinner and lighter.
However, W-LED (white LED) backlights are commonly used in the market. In fact, such backlights only replace the components that emit light, and the display effect is very weak or not improved. The RGB-LED (three-color LED), which has an obvious improvement in the display performance of the liquid crystal product, has an obvious improvement in display effect, but at the same time, the production cost is high, so it is applied to a high-priced LCD TV. At present, the LED display referred to by the merchant refers to a display product using a white LED backlight, and the difference from the ordinary liquid crystal display is the change of the backlight. OLED is the abbreviation of English OrganicLight-EmittingDiode, which is called organic light-emitting diode or organic light-emitting display.
In fact, this principle of luminescence was discovered as early as 1936, but it was not until 1987 that Kodak introduced the OLED double-layer device that OLEDs attracted attention as a commercially available and excellent flat panel display technology. OLED display has self-illumination, no need for backlight, high contrast, thin thickness, wide viewing angle, fast response, flexible panel, wide temperature range, simple structure and simple process. It is considered to be the next generation of flat panel display emerging application technology. Many people are easy to associate OLED with LED backlights that are currently hyped by LED display manufacturers. In fact, OLED 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.
