Embodiment approach

[0070]In this implementation manner, optionally, the start time and the end time of the first time period are respectively before the start time and the end time of the signal input time period of the first sub-pixel row; The start time and the end time are respectively before the start time and the end time of the signal input period to the second sub-pixel row.

[0071] In another optional embodiment, the data signal terminal 107 is electrically connected to the first data line 103 and the second data line 104 through the time division multiplexing circuit 106, so that the data signal output from the data signal terminal 107 is divided into two parts. The first data line 103 and the second data line 104 are input in time and place, including:

[0072] During the first period of time, the data signal terminal 107 is electrically connected to the first data line 103 connected to the odd-numbered sub-pixel columns through the first gate branch in the time-division multiplexing ...

Abstract

The present application provides a display panel, a driving method thereof, and a display device. The display panel includes: a sub-pixel array, a grid line, a first data line, a second data line, a pixel control circuit, a time-division multiplexing circuit and a data signal terminal; a plurality of sub-pixel units in the sub-pixel array form a plurality of sub-pixel rows and A plurality of sub-pixel columns; each sub-pixel unit in each sub-pixel row is electrically connected to the grid line, and each sub-pixel unit in the sub-pixel row is electrically connected to the pixel control circuit through the grid line; each sub-pixel unit in the odd-numbered sub-pixel row is electrically connected to The first data line is electrically connected, and each sub-pixel unit in the even-numbered sub-pixel row is electrically connected with the second data line; the first data line, the second data line and the data signal terminal are all electrically connected with the time-division multiplexing circuit. The present application can prolong the compensation time for each sub-pixel unit, thereby improving the compensation capability for Vth, improving the display unevenness of the display panel, and making the display panel maintain a better display effect at a higher refresh frequency.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to a display panel, a driving method thereof, and a display device. Background technique [0002] VR (Virtual Reality, Virtual Reality) display brings people a new visual experience, more and more people's attention and love, and mobile games have gradually become an important entertainment and leisure method for users. [0003] Both VR display and game mode require the display panel to increase the refresh rate. When the refresh rate of the display panel is high (for example, 120Hz), the traditional driving method has insufficient compensation ability for the threshold voltage Vth of the pixel circuit in the sub-pixel unit. It will cause uneven display on the display panel and affect the display effect. SUMMARY OF THE INVENTION [0004] Aiming at the shortcomings of the prior art, the present application proposes a display panel, a...
