Most OLED screens used by BOE adopt "Zhou Dongyu arrangement", that is, the pixel arrangement of 2in 1, which is characterized by dividing the green sub-pixel into two. By the end of 2020, the screens of Huawei Mate20Pro and P30Pro mobile phones will adopt BOE organic light-emitting diode Zhou Dongyu arrangement.
BOE should also avoid Samsung's own patent of RGBG diamond pentagon layout, especially using RGBG delta sub-pixel arrangement on its own OLED screen, which can also be called triangular pentagon. In fact, both companies adopt the arrangement of Zhou Dongyu.
Pentile array and its variant RGGB- Delta array both choose blue sub-pixel scheme for adjacent pixels. Compared with the standard RGB array, both of them have the disadvantage of pixel loss. The RGB Delta array is only about 77% of the standard RGB array, while the Samsung Diamond array is 80%.
However, the actual resolution of Zhou Dongyu arrangement in some directions will decrease, which will lead to problems such as insufficient screen fineness, color cast at the edge of the display content and so on. Of course, it also has the advantages of long service life and strong anti-aliasing ability.
Extended data:
The OLED screen is a flexible screen, which also means that it can be bent. Then, like a full-screen mobile phone, by bending and folding the organic light-emitting diode screen up and down, the border can be made narrower, a higher screen ratio can be achieved, and a more perfect full-screen can be made. Therefore, without exception, as long as it is a full-screen mobile phone with an ultra-high screen ratio, it must use an organic light-emitting diode screen.
Organic light-emitting diode screen also has the advantage of self-luminescence, which basically consumes no power when displaying black, which can make the mobile phone more power-saving. At the same time, the display color gamut, brightness and viewing angle of OLED should be better. The specific performance is that you can see more clearly under strong light, and the colors are more gorgeous and clear.
