Embodiment 1

[0036] Embodiment 1 of the present invention is the row-column time-slice distribution recombination scanning modulation method k=3, n s = 3·n s ’ to complete the reorganization of the row and column time slice distribution, and the new row scanning period T L '=T s / (3L), its working process is as follows image 3 Shown:

[0037] Among them, the display data is between 0 and 255, because the number of gray levels is n s = 3·n s '=255, so the time slice T corresponding to the gray level CLK The number M is 255 from 1 to 255. The row period T in the background art L =255×T CLK ;frame period T s =L×T L ;Aside from the frame period being unchanged, the following adjustments occur: new row scan period T L '=T s / (L·k)=T s / 3L=85×T CLK , the frame period can be expressed as T s =L×T L =3×L×T L ’; The five adjacent points of this line show that the data K values ​​are 0, 1, 84, 169 and 255 respectively, and these values ​​​​are distributed in the new line scan; in n...

Embodiment 2

[0039] Embodiment 2: Embodiment 2 of the present invention is the row-column time-slice distribution recombination scanning modulation method k=5 and n s =5·n s 'Complete the row and column time slice distribution recombination of the new row scanning period T L '=T s / (5L), its working process is as follows Figure 4 Shown:

[0040] Among them, the display data is between 0 and 255, because the number of gray levels is n s =5n s '=255, so the time slice T corresponding to the gray level CLK The number M is 255 from 1 to 255. The row period T in the background art L =255×T CLK ;frame period T s =L×T L ;Aside from the frame period being unchanged, the following adjustments occur: new row scan period T L '=T s / (L·k)=T s / 5L=51×T CLK , the frame period can be expressed as T s =L×T L =5×L×T L ’; The five adjacent points of this line show that the data K values ​​are 0, 1, 84, 169 and 255 respectively, and these values ​​​​are distributed in the new line scan; in ...

Description

Technical field: [0001] The invention belongs to the technical field of flat-panel video display, and relates to a time-slice scanning gray-scale control method of a flat-panel display, in particular to a row-column time-slice distribution recombination scanning modulation method of a flat-panel display. technical background: [0002] For a flat panel display, it consists of many display pixels. Each display pixel of a monochrome display has only one color, and a pixel of a color display consists of two to three primary color pixels of different colors. A flat-panel display module with an M×N primary color pixel dot matrix contains M lines of row input lighting signals and N lines of column input lighting signals. When one row input lighting signal and one column input lighting signal are valid at the same time, the primary color pixel at the intersection point emits light. Generally speaking, the row input lighting signal of each row of the screen is common, and one row i...
