What’s the difference between a cloud classroom: hunting AMOLED and LCD, should choose which?

display screen has always been a key factor in smartphones. In addition to the resolution, screen size, display technology is also increasingly become the OEM brand of configuration standards. Usually, born a vendors will promote a screen display technology, such as samsung picked AMOLED, HTC LCD. About these two different display superiority and inferiority, differences because of the analysis of different angles. So what exactly is a AMOLED and LCD? What is the advantages and disadvantages between them?

technology on different: AMOLED is our own light shine, but is to rely on backlit LCD light source

LCD technology is somewhat complicated, we strive for in the most simple language to describe you. LCD is like one side can be connected to the power of the curtain, crystal through the horizontal and vertical direction of the flow after arrangement shows images. But the curtain is not our own light shine, it need to be done with the help of a backlight source. In addition, the LCD screen mainly using red, green, blue three colors produce a variety of colors. And AMOLED USES multiple tiny red, green, and blue markers (LED). By adjusting the voltage, the control the brightness of the photoelectric, resulting in a different color. Especially in the black background, AMOLED just need to put out all the lights that can be implemented. That is said that less electricity.

display effect on different: AMELOD colour more impact, and LCD light more natural

we must first understand a concept – the color gamut. Color gamut namely the color of the human eye can recognize combined. Most of the LCD screen, matching with the standard of the RGB color gamut range and LCD color looks more natural (someone said it shows the color slants shallow). The AMOLED color range is wider, and thus the image after reduction is more exquisite, more impact. The figure below illustrates the LCD for us and AMOLED screen color gamut range. Wider color gamut, however, does not necessarily mean better. Because it will make some pictures of color is too full, or distortions.

energy dissipation and the different life: although AMOLED occupies a certain advantage, but there are still problems with the

overall, compared with LCD AMOLED or there is advantage. For example, AMOLED screen in LED response speed faster than in the LCD liquid crystal; AMOLED is larger than the Angle of the LCD in the perspective of view affects the screen brightness. Another notable problem is energy and longevity. Due to the LCD is to rely on a backlight source, thus the higher energy consumption of the screen. However, OLED screen in different color LED power consumption, such as blue leds need higher energy consumption and thus the burning rate is higher, it also means that the blue LED a shorter lifespan. This is why the AMOLED screen after using for a long time there will be a color becomes weak.

Relative merits of

? A: now each have strengths, choose different from person to person

although AMOLED have more wide color gamut, can be qualified LCD screen is much more realistic. In addition, the service life of the LCD is longer. But if you pay more attention to the impact of the color, and hopes to lower energy consumption, it is best to choose AMOLED.
