Lamp beads refer to the use of LEDs (light emitting diodes) as the backlight source of the liquid crystal flashing screen, while the LED lamp beads flasher only has the backlight source of the liquid crystal flasher from the traditional CCFL cold light tube (similar to fluorescent lamps) to LED (light emitting diode) . The imaging principle of liquid crystal can be simply understood as that the external applied voltage causes the liquid crystal molecules to deflect and block the transparency of the light declared by the backlight source like a gate, and then the light is projected on the colorful filters of different colors to form a picture.
LED flashing screen is a combination of microelectronics skills, computer skills, and information processing. With its bright colors, wide dynamic programming, high brightness, long life, stable and reliable operation, etc., it has become a very advantageous mass flashing medium. LED flashing The screen has been widely used in large squares, commercial advertisements, stadiums, information transmission, press releases, securities trading, etc., and can meet the needs of different environments. The LED flashing screen is a flashing method by manipulating semiconductor light-emitting diodes. Its approximate posture is composed of many generally red light-emitting diodes, which flash characters by turning on and off the lights. A flashing screen used to flash various information such as text, graphics, pictures, animation, market quotations, videos, and video signals.
OLED flash screens are self-luminous, do not need backlight, high contrast, thin thickness, wide viewing angle, fast response speed, can be used for flexible panels, wide application temperature planning, structure and process are relatively simple and other excellent characteristics, are I thought it was the next-generation flat flasher new application technology.
Many netizens simply associate OLED with LED lamp beads, which are more hyped by manufacturers. In fact, OLED and LED lamp beads are completely different flashing skills. OLED emits light by driving the organic thin film itself through electric current. The light emitted can be monochromatic such as red, green, blue, white, etc., and it can also achieve full-color effect. So OLED is a new light-emitting principle different from CRT, LED and liquid crystal technology.
In general, LED flash screen, deep ultraviolet LED lamp beads, and OLED are three completely different imaging techniques.
