How to identify the authenticity of OLED oled modules color

In the MP3 market some time ago, due to the intensity of competition, out of nearly 100 production workshops, there are many well-known manufacturers, and the surviving firms will soon face another round of competition at the end. Market competition brought a decline in industry profits decline in industry profits will bring a return on investment for longer than this time, companies in the industry to make the modifications, the so-called change the pass, the same death. Positive market atmosphere so many vendors make a lot of effort. However, recently, we found a lot of pseudo-news appeared on the market, the publicity specifications and product specifications are not the same data, the phenomenon is particularly serious in the MP3 screen material, many manufacturers obviously produced CSTN screen, but propaganda OLED screen, which also has many well-known brand, which has led to great confusion to the message. In order to eliminate consumers worry to buy a fake screen concerns, which teach you some of the ways to identify.8x2 lcd display
First, let us understand some MP3 screen material, MP3 players, in accordance with its display can be divided into ordinary LCD screen and a color LCD screen, color TFT, OLED color display, CSTN color screen can be divided into the market now , using the most OLED CSTN two kinds of material, the two screen with 60005 thousand color full-color, up to shoddy on the market, it was in these two kinds of material. Xiao Bian today would say the focus is how to distinguish between the two kinds of screen.
First, the color distinction. OLED color CSTN screen is very easy to distinguish, OLED because it is a self-light emitting, No background light material, so uniform in color, the color is relatively bright, close to the original effect CSTN color level worse than OLED and translucent, solid black screen is displayed, CSTN still will be revealed very slight background light, makes the whole color is not well-proportioned, which is CSTN typical performance.
Second, wide viewing angles and limited degree angle difference: the viewing angle of the OLED is very large, can reach 170 degrees, regardless of the angle at which we can clearly see the font and color of the screen above, at the same time , OLED in the sun can still see the screen display, CSTN can not achieve this effect, the viewing angle is far less than the OLED can only be seen from the front of the screen inside the color, the possibility of other angles, CSTN did not see clearly Furthermore CSTN screen in the sunlight will darken see clearly. This is the biggest difference between the two, is also the easiest door to identify skills.20x2 oled
