Previously, the author wrote an article discussing IGZO screen technology（ Click to view ）。 As mentioned in the article, Meizu's latest MX2 mobile phone does not use the previously rumored Sharp IGZO technology, but a more excellent driver technology. According to our visual comparison of the real machine, we can find that the MX2 has greatly improved the screen of the previous generation MX, with better display permeability and richer colors. So, what kind of screen does this flagship model use? At present, the official has not given the answer directly, and the author from More information has been found in. You can refer to it here for your reference.

The view of this paper is that the CG Si technology is used in Meizu MX2 screen, which is mainly discussed from the technical aspects:

Although IGZO has higher picture quality, lower power consumption, and smoother touch function than a-Si (amorphous silicon), its electronic movement speed and picture fineness are slightly lower than CG Si (Continuous Grain Silicon) and LTPS (Low Temperature Poly silicon), On the whole, it is suitable for terminal products whose demand is between a-Si and LTPS, and has cost advantages. The main supply targets are tablet computers and Ultrabooks. Generally speaking, Sharp currently uses LTPS or CG Si for 300ppi and above, and IGZO for 300ppi and below. Due to the cost advantage of IGZO, Sharp will continue to develop IGZO to make it used for finer screens.

What is CG Si? It can be seen from foreign materials that CG Si is a variant of LTPS, which uses Sharp's unique glass substrate manufacturing process. Its electronic movement rate is three times that of LTPS and 600 times that of a-Si. It can achieve a very high aperture ratio (the aperture ratio is the ratio of the light transmitting part of a sub-pixel to the entire area). A high aperture ratio means that the light transmittance of the panel is increased: under the same backlight, the screen looks brighter. It can achieve higher contrast and can be clearly seen even in the sun. The display effect of the display screen is more exquisite and the color saturation is better.

Similarly, at the Meizu MX2 launch conference, a "New Mode 2" technology was also mentioned, which has three times the electronic movement speed, higher opening rate, 1000:1 contrast, and more accurate color performance, all of which are very similar to CG Si. Although the official did not specify the comparison object of "three times the electronic movement speed", we can identify it as the previous generation Meizu MX. Since the LTPS technology used by MX is exactly three times the difference in electronic movement rate with CG Si, we can conclude that the CG Si technology is used in Meizu MX2 screen.

Because the high opening rate of CG Si can get the same screen brightness under lower backlight, and the high-speed electronic mobility rate can also reduce the screen driving power, which can further reduce the screen power consumption in general, so that the overall endurance of the MX2 can be well guaranteed. This is the secret of the "low-power screen" promoted by Meizu MX2.
