Display panel, driving method thereof 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 for data lines and are beneficial for realizing the design of a high screen-to-body ratio and a narrow frame. Moreover, for the same sub-pixel group connected with the same gating circuit, the gating circuit outputs a data signal to the sub-pixel group in sequence when the first scanning line corresponding to the sub-pixel group outputs a scanning signal, and completes the output of the data signal to the sub-pixel group before the secondscanning line corresponding to the sub-pixel group outputs the scanning signal. Namely, for the same sub-pixel group, the sub-pixels are divided into multiple sub-pixels; the time of outputting the scanning signal by the first scanning line is overlapped with the time of outputting the data signal by the gating circuit; therefore, the charging time of the scanning signal can be ensured to be the time for scanning a row of pixels, namely, the scanning signal is ensured to have enough charging time, so that vertical stripes caused by relatively short charging time of the scanning signal can be eliminated while high-frequency display is realized, and the display effect is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a driving method thereof and a display device. Background technique [0002] The electroluminescence display is a self-luminous device, which can realize the display function without setting a backlight module, which makes the display light and thin, 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 60Hz, and high-frequency products can be understood as products with a scanning frequency of 120Hz. 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 ch...

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.
