>> LCD screen why lose to AMOLED screen? 18th,Dec,2017
We all know that the screen is good or bad has been a lot of mobile phone users concerned about one of the main factors, not only the size of the phone screen has a very different in different brands of screen their own characteristics are also very distinct.
The company is located in:
Today, according to Taiwanese media reports, Samsung is increasing its production of its own AMOLEDP screen production, shipments will reach 560 million units, an increase of 114% compared to 2015, the reason is that this year the original use of LCD screen Of the handset manufacturers have given up the LCD screen. And replaced by Samsung's AMOLED screen, of course, there is a key reason is that Apple will be out next year iphone8 AMOLED screen will be used, it is estimated that next year Samsung will produce 50 million for Apple's AMOLED screen to 2019 is expected to reach 120 million pieces of the scale, the other hand, a series of reasons, LCD screen will be left to the marginalized, but MOLED screen spring will gradually come.
In addition, the LCD screen in the technology where lost to the MOLED screen, let me summarize for everyone.
First, the technical principle
LCD This is English (Liquid Crystal Display) abbreviation, the Chinese name full name is the LCD display, LCD driver can be divided into Active Matrix and Passive Matrix these two models, most of the current mobile LCD screen is Active Matrix. LCD all the light-emitting pixels need to rely on a unified backlight layer to light, which means that the LCD needs backlighting to display.
In contrast, AMOLED display will be much simpler, although also rely on a series of complex organic thin film material to achieve the purpose of emitting light, but his biggest advantage is that each pixel will have a high degree of controllability , Each pixel can be independent of the switch, which will be able to achieve independent of light.
Followed by the color gamut
LCD light source will be some of the more simple, there is not much color in it, strictly speaking, the world does not exist in a white light and the corresponding wavelength, white light can only be a variety of mixed colors, LCD only through Backlight + phosphor to produce white backlight, the most commonly used is the blue backlight = yellow phosphor combination. So the LCD screen usually will be a bit pan-blue or green, of course, considering the LCD usually use blue backlight, this result is not out of line.
At this point, AMOLED screen will look much better, because of its screen color performance is very good, especially in the display of white, and the real white is very similar, there is another point compared to the LCD screen, AMOLED screen in the sense of the screen will be more abundant, the gamut will be broader, it can display more colors, the display will be more clever, so, in this gamut, AMOLED screen is superior.
