[0003] However, in the existing digital drive scanning algorithm, the scanning time of each row of sub-pixels is related to the number of rows of the display panel. For a display panel with a large number of sub-pixel rows, the scanning time of each row of sub-pixels is very short, resulting in a poor display effect. poor

Embodiment Construction
[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0031] As mentioned in the background technology, in the existing digital drive scanning algorithm, the scanning time of each row of pixels is related to the number of rows of the display panel, so for a display panel with a large number of rows, the scanning time of each row of pixels is very short , resulting in a poor display effect. The inventors have found through research that the reason for the above problems is that the existing digital drive scanning algorithm usually adopts a progressive scanning method,...

The embodiment of the invention discloses a digital driving method of a display panel and the display panel. The display panel comprises m rows and n columns of sub-pixels arranged in an array, a plurality of scanning lines and a plurality of data lines. Each scanning line is connected with one row of sub-pixels. Each data line is connected with one column of sub-pixels, and m and n are integers greater than or equal to 1. The digital driving method of the display panel comprises the steps of providing scanning pulse signals for all scanning lines at the same time, and first data voltage is provided for all data lines at the same time; providing a second data voltage to each data line one by one, supplying a second data voltage to one data line; providing the scanning pulse signals for thescanning lines connected with the sub-pixels needing to be written with the second data voltage at the same time, so that scanning time of each row of sub-pixels is irrelevant to the row number of the sub-pixels in the display panel. The problem of abnormal display caused by short scanning time of each row of sub-pixels due to too many rows of an existing display panel is solved.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a digital driving method for a display panel and the display panel. Background technique [0002] With the development of display technology, digital drive has been more and more widely used because of its advantages of low image noise and fast switching speed. [0003] However, in the existing digital drive scanning algorithm, the scanning time of each row of sub-pixels is related to the number of rows of the display panel. For a display panel with a large number of sub-pixel rows, the scanning time of each row of sub-pixels is very short, resulting in a poor display effect. poor. Contents of the invention [0004] The invention provides a digital driving method of a display panel and the display panel, so that the scanning duration of each row of pixels is independent of the number of sub-pixel rows in the display panel, and the display effect is ...
