Each pixel unit is composed of two sub-pixels, which are arranged in the order of "red + green", "green + blue", or "blue + red".

However, in the conventional SPR technology, the content of one line of the source image needs to be displayed by using the green sub-pixel in the adjacent pixel unit, which results in a large loss of resolution.
