The data writing control unit is respectively electrically connected with the data lines in a one-to-one correspondence mode, under the coordination of scanning signals, the data writing control unit controls the data lines to write data signal voltages into each pixel, so that light with P different brightnesses is respectively emitted from every count of P pixels starting from a first pixel arranged along the row direction in each row of pixels, and light with P different brightnesses is respectively emitted from every count of P pixels starting from a first pixel arranged along the column direction in each column of pixels, M and N are integers larger than or equal to 2, and P is an integer between 2 and N. Therefore, the vertical stripe appearing rules of the P-column pixels corresponding to the adjacent P rows are different, complementation is realized, the problem of vertical stripe appearing in display is improved macroscopically, the problem of vertical stripe appearing is avoided, and the display quality is improved.

In one embodiment, where P is 2, emitting light of P different luminances for every count of P pixels from a first pixel arranged in a row direction in each row of pixels, and emitting light of P different luminances for every count of P pixels from a first pixel arranged in a column direction in each column of pixels includes: the pixels in the odd-numbered rows and the pixels in the even-numbered columns emit light with a first brightness, and the pixels in the odd-numbered rows and the pixels in the even-numbered columns emit light with a second brightness, as shown in fig. 2.

In one embodiment, P is 3, and every three adjacent pixels arranged along the row direction in each row of pixels respectively emit light of three different luminances, wherein the three different luminances include a first luminance, a second luminance, and a third luminance. Every adjacent three pixels arranged along the column direction in each column of pixels respectively emit light with three different luminances, namely, the adjacent three pixels emit light with three different luminances. There are various arrangement ways that can simultaneously satisfy that every adjacent three pixels arranged along the row direction in each row of pixels respectively emit light of three different luminances and every adjacent three pixels arranged along the column direction in each column of pixels respectively emit light of three different luminances, for example, in the first row of pixels in adjacent three columns of pixels in adjacent three rows of pixels: the first column of pixels emits light with a first brightness, the second column of pixels emits light with a second brightness, and the third column of pixels emits light with a third brightness; in the second row of pixels: the first column of pixels emits light with second brightness, the second column of pixels emits light with third brightness, and the third column of pixels emits light with first brightness; third row: the first column emits light with third brightness, the second column emits light with first brightness, and the third column emits light with second brightness; fourth row: the first column emits light with a first brightness, the second column emits light with a second brightness, and the third column emits light with a third brightness; the fifth element: the first column of pixels emits light with the second brightness, the second column of pixels emits light with the third brightness, and the third column of pixels emits light with the first brightness; and so on as shown in figure 3.

It should be understood that, in a plurality of pixels distributed in an N-column M-row array, each P counted number of pixels from the first pixel arranged in the row direction in each row of pixels emits P kinds of light with different brightness, and in each column of pixels, each P counted number of pixels from the first pixel arranged in the column direction in each column of pixels emits P kinds of light with different brightness, the arrangement form described above, that is, the form shown in fig. 2 and 3, may be adopted, and the present invention is not limited thereto.
