Display panel, method for driving the same, and display device

Abstract

The invention discloses a display panel, a driving method thereof and a display device, which utilize a plurality of gating circuits to provide data signals to data lines, which is beneficial to realize the design of high screen ratio and narrow frame. In addition, for the same sub-pixel group connected to the same gating circuit, the gating circuit sequentially outputs data signals to the sub-pixel group when the first scan line corresponding to the sub-pixel group outputs the scan signal, and the sub-pixel group corresponds to the sub-pixel group. Before the second scan line outputs the scan signal, the output of the data signal to the sub-pixel group is completed. That is, for the same sub-pixel group, the time when the first scan line outputs the scan signal and the time when the gate circuit outputs the data signal is in an overlapping relationship. Therefore, it can be ensured that the charging time of the scan signal is the time to scan a row of pixels, that is, to ensure that the scan signal is charged. There is enough charging time, so that while realizing high-frequency display, vertical stripes that appear due to the short charging time of the scanning signal can be eliminated, thereby improving the display effect.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel, a driving method thereof and a display device. Background technique [0002] The electroluminescent display is a self-luminous device, which can realize the display function without setting a backlight module, which makes the display have the characteristics of light weight and thinness, and has a wide range of applications in various fields. [0003] Electroluminescent displays generally have two specifications: conventional products and high-frequency products. Conventional products can be understood as products with a scanning frequency of 60 Hz, and high-frequency products can be understood as products with a scanning frequency of 120 Hz. At present, conventional products are usually equipped with a gate circuit, and the charging time of the corresponding scanning signal is generally less than 0.5 microseconds; and if the high-frequency product ...

AI Technical Summary

Problems solved by technology

At present, conventional products are usually equipped with a gate circuit, and the charging time of the corresponding scanning signal is generally less than 0.5 microseconds; and if the high-frequency product adopts the structure of conventional products, the charging time of the scanning signal is also less than 0.5 microseconds. When the charging time of the scanning signal is seriously insufficient, the problem of vertical lines is easy to appear when the screen is displayed, and the display effect is reduced.
