Problems solved by technology

However, in the existing electroluminescent diode display panel, limited by the LTPS (Low Temperature Poly-silicon, low temperature polysilicon) process problem, the threshold voltage of each triode is different, and the control current of each pixel cannot be accurately controlled, so Threshold voltage compensation for each pixel is required to achieve a more uniform and fine display panel
With the increasingly demanding display requirements of consumers, the resolution requirements are getting higher and higher, resulting in shorter and shorter charging time for each pixel, it is difficult to compensate the threshold voltage within the limited charging time, resulting in poor display effect

Embodiment Construction

[0061]In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0062] One embodiment of the present invention provides m rows and n columns of sub-pixels; multiple gate lines, when i<(m+1) / 2, the i-th gate line drives all the sub-pixels in the (2i-1)th row and the 2ith row The sub-pixels; if m is an odd number, when i=(m+1) / 2, the i-th gate line drives the sub-pixels in the m-th row; multiple data lines; each row of sub-pixels corresponds to two data lines line, the two data lines include a first data line and a second data line, wherein the first data line is connected to the sub-pixe...

Abstract

The invention discloses an array substrate, and the array substrate comprises m*n subpixels. The adjacent odd-numbered and even-numbered rows are controlled at the same time through one grid line, andone column of pixels are controlled through two data lines. The embodiment of the invention provides the array substrate, a driving method, a display panel and display equipment. The compensation ofa threshold voltage and a voltage drop of the array substrate can be achieved, and the uniformity of a drive current is improved, thereby improving the display uniformity of the display panel, reducing the leaked current so as to guarantee the high contrast during a black state, and improving the display effect of the electroluminescent diode array substrate, display panel and display equipment.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a driving method, a display panel and a display device. Background technique [0002] As a current-mode light-emitting device, the electroluminescent diode has the advantages of low energy consumption, low production cost, self-illumination, wide viewing angle and fast response speed, and is widely used in the field of high-performance display. However, in the existing electroluminescent diode display panel, limited by the LTPS (Low Temperature Poly-silicon, low temperature polysilicon) process problem, the threshold voltage of each triode is different, and the control current of each pixel cannot be accurately controlled, so Threshold voltage compensation for each pixel is required to achieve a more uniform and fine display panel. With the increasingly demanding display requirements of consumers, the resolution requirements are getting higher and hi...
