But the number of pixels of three colors is reduced by one third, and six sub-pixels * * * share one pixel, so the actual resolution is lower, and the jagged edge is more obvious at low resolution.
The reason for this arrangement is that the PenTile arrangement has been patented by Samsung. Therefore, domestic manufacturers must find new ways to solve the sub-pixel lifetime problem. Therefore, BOE's "winter rain arrangement" (similar to PenTile arrangement) extends the screen life by expanding the blue-red sub-pixel area, avoiding Samsung's patent.
Extended data:
The screen display consists of pixels, including red, green and blue sub-pixels, which is the professional name of RGB. Different colors can be displayed through the combination of RGB, and the arrangement of RGB will also affect the display effect of the screen.
As we all know, Huawei P40 series adopts BOE's screen. You can look at the following two comparison pictures, the triangle arrangement of BOE screen on the left and the diamond pixel arrangement of Samsung screen on the right.
This is the pixel arrangement of the screen as seen under the microscope. Obviously, it can be found that the diamond-shaped pixels on the Samsung screen are arranged more clearly. In other words, the mobile phone with diamond-shaped pixel arrangement on Samsung screen is superior to the triangular arrangement on BOE screen in terms of screen clarity.
