Problems solved by technology

However, although two adjacent gate lines give the same timing, they are two independent gate lines in the design. Since the gate lines occupy a certain space, the pixel opening area is compressed and the aperture ratio is reduced.
At the same time, the number of gate lines is large, which leads to an increase in the number of gate drive chips, an increase in cost, and is not conducive to the realization of narrow borders.

Embodiment 1

[0021] combine figure 1 and image 3 As shown, in this embodiment, a display substrate is provided, including a plurality of gate lines 10 and a plurality of data lines 20 , and the gate lines 10 and data lines 20 are distributed across and define a plurality of sub-pixel regions 100 . There are two rows of sub-pixel regions 100 between two adjacent gate lines 10 , and two data lines 20 between two adjacent columns of sub-pixel regions 100 . Each sub-pixel region 100 includes a thin film transistor 1 , the gate electrode of the thin film transistor 1 is integrally formed with the gate line 10 , the source electrode 2 is connected to the data line 20 , and the corresponding thin film transistor 1 is turned on or off through the gate line 10 .

[0022] The thin film transistors 1 of two adjacent rows of sub-pixel regions 100 located on both sides of a gate line 10 are connected to the gate line 10, and the thin film transistors 1 of adjacent two rows of sub-pixel regions locate...

Embodiment 2

[0049] This embodiment provides a display device and a driving method thereof. The display device adopts the display substrate in the first embodiment, and since the number of gate lines is halved, the aperture ratio is improved. At the same time, halving the number of gate lines reduces the number of gate drive chips or gate drive circuits, reduces costs, and facilitates the realization of narrow borders. In addition, since the thin film transistors in one row of sub-pixel regions can open the charging time of two rows of sub-pixels, sufficient charging time is provided, thereby increasing the pixel charging rate and improving display quality.

[0050] Wherein, the display device may be a liquid crystal display device, an organic electroluminescent display device, or the like.

[0051] The driving method of the above display device includes:

[0052] The thin film transistors in two adjacent rows of sub-pixel regions located on both sides of the gate line are simultaneously...

Abstract

A display substrate, a display device and a driving method thereof are provided. The display substrate includes a plurality of gate lines and a plurality of data lines. The plurality of gate lines crosses the plurality of data lines to define a plurality of sub-pixel regions. Each of the plurality of sub-pixel regions includes a TFT connected to one of the plurality of data lines. Two rows of sub-pixel regions are arranged between every two adjacent gate lines, and two data lines of the plurality of data lines are arranged between every two adjacent columns of sub-pixel regions. TFTs in two adjacent rows of sub-pixel regions at two sides of one gate line of the plurality of gate lines are connected to the gate line and connected to different data lines.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate, a display device and a driving method thereof. Background technique [0002] In the field of flat panel display technology, thin film transistors (Thin Film Transistor, TFT for short) have the advantages of small size, low power consumption, and relatively low manufacturing cost, and are widely used as driving devices in flat panel display technology. [0003] For a TFT display device, the TFT is controlled to be turned on or off through the gate line, and when the TFT is turned on, the pixel voltage is transmitted to the corresponding pixel through the data line. The pixel charging rate is defined as the ratio of the pixel voltage of the pixel to the voltage written on the data line. The pixel voltage is related to charging time, TFT turn-on current, etc. Taking a 120Hz display device (with a resolution of 3840*2160) as an example, the charging ti...
