Background
With the rapid development of AR, VR, and MR, microdisplay has become one of the key technologies. In the field of micro-display, there are two display modes of spatial color and time-sequential color. Compared with the traditional display, the micro display has the advantages of small size, high resolution and the like, but with the higher and higher resolution of a video source and the comprehensive consideration of the aspects of the process, the physical size of pixels, the cost and the like, the area of a micro display chip is difficult to be smaller.
The most common display mode of the LCoS chip is RGB spatial color display, that is, any resolution pixel point in the RGB color space can represent one color, and the sequential color utilizes the temporal property of the vision of human eyes to rapidly display tricolor light in a time-sharing manner, so that human eyes feel a stable color image, but the current micro display chip basically only supports displaying a video source with corresponding resolution, although some methods capable of supporting displaying video sources with multiple resolutions are available, for example, a video display system for improving display resolution disclosed in patent application CN110136644A in 2019, 08 and 16, retains the pixel information of the video source, but performs 4-sample mode display only on a plurality of physical pixel point sets with certain pixel structures of spatial color; another patent application CN111402781A discloses a display system with reduced display screen area by pixel space sampling in 2020, month 07 and 10, which loses part of the pixel information of the video source during sampling and has poor effect; however, for time-series colors, pixel points correspond to physical pixel points one by one, and one pixel point corresponds to one physical pixel point, so that the physical pixel point needs to be broken through for processing, and no related method exists.
Therefore, the video source with the resolution supported by the current micro display chip is relatively fixed, resulting in low universality.

In an embodiment, the remaining sub-data frames are partially overlapped in the following manner: the overlapping area of each sub data frame in the horizontal direction is (f-1)/f, (f-2)/f, (f-3)/f … 1/f, and f is the value in the horizontal direction of the sampling mode; the overlapping area of each sub data frame in the longitudinal direction is (g-1)/g, (g-2)/g, (g-3)/g … 1/g, g-1 sub data frames are totally, and g is a value in the longitudinal direction of the sampling mode; the overlap area at the crossing point of the transverse direction and the longitudinal direction in the oblique direction is the product of the overlap areas of the transverse sub data frames and the transverse sub data frames, namely ((f-1)/f) ((g-1)/g), and f × g-f-g +1 sub frames.
Step S280, after the processed data stream is cached and analyzed, the pixel value of the physical pixel point is output for display.
The displayed pixel structure can be any one of a field shape, a triangle shape, an L shape and a long strip shape, and can also be other pixel structures, and the corresponding pixel structure can be adopted for displaying according to the micro display chip and actual needs.

（V1(2,2)+V2(2,3)*2/3+V2(2,1)/3+V3(2,2)/3+V3(2,1)*2/3+V4(2,2)*2/3+V4(1,2)/3+V5(2,2)/3+V5(1,2)*2/3+V6(2,2)*4/9+V6(2,1)*2/9+V6(1,2)*2/9+V6(1,1)/9+V7(2,2)*2/9+V7(2,1)*4/9+V7(1,2)/9+V7(1,1)*2/9+V8(2,2)*2/9+V8(2,1)/9+V8(1,2)*4/9+V8(1,1)*2/9+V9(2,2)/9+V9(2,1)*2/9+V9(1,2)*2/9+V9(1,1)*4/9 ）/9
