How to quickly identify real and fake OLED screens

1. The two materials, OLED and CSTN, are easy to distinguish in color. Because OLED is a self-illuminating material that does not require a background light source, the color is more uniform and the color is brighter, which is close to the original effect. The CSTN color level and light transmittance are worse than OLED. When displaying a pure black picture, a very slight background light will still be revealed, making the whole color appear uneven, which is also a typical performance. The flooded CSTN color screen on the market is much inferior to the screen in terms of color brilliance and brightness. Many users of CSTN screen products have reported that the machine cannot see the content in sunlight, and the painting also has smearing phenomenon.

2.The difference between a wide viewing angle and a limited viewing angle

The viewing angle of OLED is very large, which can reach 170&deg. No matter what angle we are in, we can see that OLED can also see the screen clearly in the sun, CSTN can not achieve this effect, its viewing angle is far less than OLED, and CSTN can not clearly display the screen, CSTN screen will be in the sun darken. Change the position and look at it from another angle. The viewing angle of the CSTN screen is narrow. Compared with the sense, the OLED screen is clear.
CSTN several times. Compared with color contrast and saturation, OLED shows the characteristics of vivid picture, while CSTN screen is dull, dull and dull.

3. Power effect      

OLED has been recognized by the industry as the next-generation mainstream display technology because of its many superior performances. Flexible and environmentally friendly design and other advantages. On the playing time of the machine, use
The MP3 of the screen is very power efficient. The OLED screen uses a very thin organic material coating and glass light, which not only saves power, but also makes the screen thinner; while the CSTN LCD device is used.

4. Price 
In the current international market, the price of an OLED screen is about 13-14 US dollars, while the CSTN screen is between 5-6 US dollars. In terms of price, it may be difficult for consumers to identify the MP3 of the special OLED screen of the product. If the price is about 100 yuan, it is entirely possible that the merchant is doing fake propaganda.
