Driving method of pixel array, driving module of pixel array and display device

摘要

The present invention provides a driving method of a pixel array, wherein the driving method includes: step 1, obtaining a theoretical brightness value of each sub-pixel for an image to be displayed; step 2, calculating an actual brightness value of each sub-pixel, the actual brightness value of a sub-pixel to be calculated is a sum of a part of the theoretical brightness value of the sub-pixel to be calculated and a part of the theoretical brightness values of a plurality of auxiliary sub-pixels corresponding to the sub-pixel to be calculated; and step 3, outputting a signal to each sub-pixel so that the brightness value of each sub-pixel reaches the actual brightness value thereof which is obtained in the step 2. The present invention further provides a driving module of a pixel array and a display device.

1. A driving method of a pixel array, the pixel array includes a plurality of repeating units, each repeating unit includes two rows of sub-pixels, each row of sub-pixels comprise four sub-pixels having different colors, in each repeating unit, first two sub-pixels in a first row have the same colors as last two sub-pixels in a second row, and last two sub-pixels in the first row have the same colors as first two sub-pixels in the second row, wherein, the driving method includes:
step 1: obtaining a theoretical brightness value of each sub-pixel for an image to be displayed; step 2: calculating an actual brightness value of each sub-pixel, the actual brightness value of a sub-pixel to be calculated is a sum of a part of the theoretical brightness value of the sub-pixel to be calculated and a part of the theoretical brightness values of a plurality of auxiliary sub-pixels corresponding to the sub-pixel to be calculated, wherein the number of the auxiliary sub-pixels corresponding to the sub-pixel to be calculated is three, the color of each auxiliary sub-pixel is the same as the color of the sub-pixel to be calculated, and the sub-pixel to be calculated and the three auxiliary sub-pixels corresponding thereto are located at four apexes of a kite respectively, or the number of the auxiliary sub-pixel corresponding to the sub-pixel to be calculated is four, the color of each auxiliary sub-pixel is different from the color of the sub-pixel to be calculated, and the four auxiliary sub-pixels are located at four apexes of a parallelogram and the sub-pixel to be calculated is located inside the parallelogram; and step 3: outputting a signal to each sub-pixel so that the brightness value of each sub-pixel reaches the actual brightness value thereof which is obtained in the step 2.
