What is OLED? What are its advantages and disadvantages?

The English full name of Organic Light-Emitting Diode is organic light-emitting Diode, which can also be called "organic light-emitting diode" or "organic laser display".

OLED has the advantages of bright colors and low power consumption, its display technology has the characteristics of self-lighting, through a very thin organic material coating and glass as a substrate, when there is a current through, these organic materials will emit light, not only the display screen viewing Angle is large, because less LED backlight, power consumption can be reduced. There is also a big feature, in the screen application design, it can be bent, so it can be used to design a wider range, such as curved screens, fingerprint identification under the screen, etc.

Advantages of OLED

The pixels on the organic light-emitting diode (OLED) screen can emit light on their own, reduce power consumption, and the screen is thin and flexible, making the colors brighter and the contrast clearer, overcoming the problem of dynamic blur, and OLED can provide higher density units and clearer images than LCD.

The disadvantages of OLED

1. Branding, color decay:

A problem unique to mobile phones - LCD screens are prone to similar problems. OLED material limit, pixel life limit, with a long screen easy to produce color bias, color decay, brand traces. But that's not the reason for OLED

2. Flash screen:

Due to the dimming mode of OLED, there may be a flickering screen phenomenon. Flicker screen refers to the screen with low flicker frequency. Although flicker can not be seen visually, long-term viewing may cause visual fatigue, but this part varies from person to person, and some people can not feel it.

3. High cost:

At present, the production difficulty and material cost of organic light-emitting diodes are higher than LCD. Although the market share is gradually increasing, it has not completely replaced the LCD screen.
