How to identify genuine and fake OLED TFT Display Module screen?

Appeared on the market a lot of pseudo-news, publicity specifications and product specifications to the same data, the phenomenon is particularly serious in the the MP3 screen material, many manufacturers are obviously production CSTN screen, but in the publicity OLED screen, where there are a lot of well-known brands, which brought a lot of confusion to consumers. In order to eliminate consumers worry to buy a fake screen concerns, we have listed here are several methods to identify genuine and fake OLED.OLED Module
On the market now, the color OLED CSTN two kinds of material, these two kinds of screen with 65K full-color, up to shoddy on the market, it was these two kinds of material.
1, the color distinction
OLED with CSTN In the color on the screen can easily distinguish, OLED because it is a self-light emitting material, no background light, so the color is uniform, bright color, close to the original effect CSTN due to the color level and translucent worse than OLED, pure black screen is displayed, CSTN still will be revealed very slight background light, makes the whole color appears to be well-balanced, which is CSTN typical performance. CSTN color screen flooding the market, brilliant color, the picture is bright than OLED screen a lot less, a lot of user feedback CSTN screen products, not see the contents of the machine under the sun, play the animation smearing.TFT Display Module
2, wide viewing angles and limited degree angle difference
OLED viewing angle is very large, can reach 170 °, no matter what point of view, we can clearly see the screen above the font and color, at the same time, OLED can see the same sun screen display; CSTN can not achieve this effect, the viewing angle is far less than OLED, and can only see the color of the inside from the front of the screen, from other perspective, CSTN can not clearly show the color of the screen, and CSTN screen will darken in the sun . Exchange position, from another point of view, we can see that the the narrow the CSTN screen viewing angle, up from sensory comparison, the OLED screen clarity and sharpening high the CSTN good times. From the color, contrast, saturation up comparison, OLED exhibit bright, vivid images, the CSTN screen dark matte painting was dull, dull, this is the biggest difference between the two, is the most easily recognizable.
