What is OLED TV, first of all, OLED (Organic Light-Emitting Diode), the full name of "organic light-emitting diode", is a display screen technology. The OLED TV is a terminal product based on OLED panels. So what are the advantages of OLED TV and what are the factors that lead to the year-on-year increase in global OLED TV shipments.
"What is an OLED TV"
Comparison of OLED TV and LED TV
The panel of the LED TV is actually an LCD liquid crystal screen, but the backlight is changed from the original CCFL fluorescent lamp to white LED lighting, so it is also called WLED (white light diode). For OLED TVs, LCD liquid crystal panels are no longer needed, and RGB color signals are directly displayed by OLED diodes. There is almost no problem with the viewing angle of liquid crystal.
Today's LCD displays use LED backlights. Since the backlight requires the effect of white light, the industry uses blue LEDs mixed with yellow phosphors to form white light. Since the blue LED is the main hardware, the blue spectrum in this white light has a peak, which causes what we call the harmful blue light to hurt the eyes. As the main carrier of entertainment in the living room, LED LCD TVs, most families choose to watch TV before going to bed at night, and even many people will turn off the lights while watching TV, plus factors such as flashing screens, causing harmful blue light to cause damage to the eyes.
Each pixel of the screen panel of the OLED TV can emit light independently, and no backlight is needed. The OLED organic light-emitting body has 33.17 million solid particles, which can automatically emit light. As long as the voltage is input into the electrode, the excitation layer can generate the required colored light. The blue light band generated is mainly concentrated at 460nm, which is not harmful blue light. It is small and has little harm to human eyes.
