LED backlight refers to the backlight of LED as a LCD display with LED, and the LED backlit display is just the backlight of the LCD display from the traditional CCFL cold light tube (similar to the sunlight) to LED (luminous diode). The imaging principle of the LCD can be simply understood. The exerting voltage of the outside world can make the liquid crystal molecular deflection block the transparency of the light as a gate, and then project the light into a color filter in different colors to form images.
The LED display is a combination of microelectronics technology, computer technology, and information processing. It has become the most advantageous public display media with its bright colors, wide dynamic range, high brightness, long life, and stable work and reliable work. It has been widely used in large squares, commercial advertising, stadiums, information dissemination, press release, securities transactions, etc., which can meet the needs of different environments. The LED display is a display method that controls the semiconductor light -emitting diode. Its generally looks like many of the red light diode that is usually red. It is used to display display screens such as text, graphics, images, animations, markets, video, video signals and other information.
The OLED display has excellent characteristics such as self -luminoma, no backlight, high contrast, thin thickness, wide perspective, fast response speed, can be used for flexion panels, wide range of temperature range, simple structure and simple process, etc. It is considered to be an emerging application technology of the next generation of graphic display.
Many netizens are easy to connect OLEDs with LED backlights with more manufacturers. In fact, OLED and LED backlight are completely different display techniques. OLED is shining by current -driven organic film. The light can be red, green, blue, white and other colors, which can also achieve full -color effects. So OLED is a new luminous principle different from CRT, LED and LCD technology.
In general, LED display, LED backlight, OLED are three completely different imaging technologies.
