How to tell the truth by looking at the ark screen?

Because of this, the Internet has narrowed the distance between people, but it has also brought some troubles, because some people can upload and publish what they have seen and heard within the scope permitted by law. However, some people create false information without verification and confirmation, which is easy to cause misunderstanding. Although there is a certain rectification system on the Internet, false information is still rampant. For example, there are a lot of false news in the market, and the publicity specifications are different from the product specifications. Seriously, many manufacturers obviously produce CSTN screens on MP3 screen materials, but they say organic light-emitting diode screens in advertisements, including many well-known brands. They are selling dog meat by hanging sheep's head, which has brought great confusion to consumers. Worried that consumers will buy fake screens, Bian Xiao listed several methods to identify the true and false OLED screens here.

How to identify true and false OLED screens? The file extension of encoded image stored in jpeg file exchange format.

First, the difference between colors.

Organic light emitting diodes and CSTN are easy to distinguish in color. Because the organic light-emitting diode is self-luminous and does not need the material of the background light source, the color is more uniform and vivid, which is close to the original effect. However, the color level and light transmittance of CSTN are worse than those of OLED. When displaying a pure black picture, it will still show a very slight background light, which makes the whole color appear asymmetric, which is also a typical performance. The CSTN color screen, which is flooded in the market, is far less bright in color and picture brightness than the screen. Many users of CSTN screen products feedback that the machine can't see the content clearly in the sun, and the painting also has tailing phenomenon.

Second, the difference between wide angle of view and limited angle of view

The viewing angle of organic light-emitting diodes is very large, which can reach170&; Degree. No matter at any angle, we can clearly see that organic light-emitting diodes can see the screen display in the sun, but CSTN can't achieve this effect, and its viewing angle is far less than that of organic light-emitting diodes. CSTN can't clearly display the screen, and CSTN will darken the screen in the sun. Change the position, change the angle, the viewing angle of CSTN screen is narrow, and the organic light-emitting diode screen is clear from the sense.

CSTN several times. Compared with color contrast and saturation, organic light-emitting diodes are bright and vivid, while CSTN screen is dull and dull.

3. Power effect

Organic light-emitting diodes (OLEDs) are recognized as the mainstream display technology of the next generation because of their superior performance. Flexibility and environmental protection design. During the playing time of the machine.

MP3 on the screen is very power-saving. The organic light-emitting diode screen adopts very thin organic material coating and glass light, which not only saves electricity, but also makes the screen thinner. Using CSTN liquid crystal display.

4. Price Grid

In the current international market, the price of an OLED screen is about 13 ~ 14 dollars, while the screen is between 5 ~ 6 dollars. In terms of price, it may be difficult for consumers to recognize the MP3 with special OLED screen. If the price is around 100 yuan, it is entirely possible that the merchants are making false propaganda.
