MP3 screen material kind
The colored screen that is applied to MP3 at present mainly divides three kinds TFT, OLED, CSTN, as regards result of revealing wholly, TFT>OLED>CSTN
TFT (Thin Film Transistor membrane transistor) ,It is initiative matrix type LCD, commonly called as really applausing, the shortcoming is power more consumptive. Reject MP3 to use for most top-grade colors on the market at present.
OLED (Organic Light Emitting Display gives out light on the display screen organically) ,It reveals technology is different from traditional LCD display mode, it is possible to give out light (not need backlight source) more lightly and voluntarily more thinly . It is used more in domestic MP3 that OLED rejects at present.
CSTN (Color Super Twisted Nematic exceeds twisting coloredly to the tabulating type) ,It is passive matrix type lLCD. CSTN is unable to realize complete black-and-white bottom, so its color reduces ability and can not far compare with TFT.
What adopted most is OLED and these two kinds of materials of CSTN on former market, that adulterated at most is by rejecting making OLED http://www.comeinchina.com/to reject of CSTN material on the market, especially some common model's products. Discern the method There are three points:
First, the visual angle of OLED is very big, can reach angle of 170 degrees, no matter on which angle, can see script and color of display screen above clearly. Meanwhile, OLED can see all the same clearly the screen reveals, but CSTN can't reach such a result under the sunshine. Its visual angle is far from being so good as OLED, can only see the color inside from the front that is rejected, on other angles, CSTN can not clearly see either, moreover, CSTN will become dark in the lower screen of the sunlight, can't see clearly. This two heavy difference most, most apt skill that recognize too.
Second, the differentiation of color. OLED and CSTN are very easy to distinguish out on the color that is rejected, because OLED is that one kind is spontaneous and smooth, does not need the material of the background light source, so seem on color evenly, the color and luster is more bright-colored, close to original result, CSTN because color rank OLED take bad compared with printing opacity, while revealing purely black picture, CSTN will still appear very slight background light, make the whole color seem lopisded, this is CSTN more typical behavior too.
Third, the price. Because OLED and CSTN have yuan of price differentials, so mark, call 128MB too or OLED of 256MB reject MP3, if price difference is http://www.av-furnitures.com/about 100 yuan, it is the big brand to make the special price to promote, otherwise cheap that mustn't buy.
