Embodiment 1

[0034] Such as figure 1 As shown, the array substrate provided by the embodiment of the present invention can be used in a liquid crystal display, and the array substrate includes n gate line groups and n+1 main gate lines G1 to Gn+1. Wherein, each main gate line is connected to the gate driver of the liquid crystal display. Each gate line group includes adjacent first gate lines and second gate lines, a first pixel group is arranged corresponding to the first gate line, and a second pixel group is arranged corresponding to the second gate line. The first pixel group includes a plurality of first pixel units arranged in rows, each first pixel unit includes a first transistor T1; the second pixel group includes a plurality of second pixel units arranged in rows, and the second pixel unit includes a second transistor T2 and switching element T3. From figure 1 It can be seen from the figure that T1, T2 and T3 are correspondingly arranged in each column of pixel units of the li...

Embodiment 2

[0053] This embodiment is basically the same as Embodiment 1, the difference is: as image 3 As shown, in this embodiment, the n+1th main gate line Gn+1 is connected to the first main gate line G1. In this way, Gn+1 and G1 can be controlled together, and the timing diagram of G1 (that is, Gn+1) can be as follows Figure 4 As shown, in the two time periods before the first time period t1 in Embodiment 1, that is, within t2n-1 and t2n in the previous round of scanning, cooperate with Gn to realize the 2n-1th row and the 2nth row The pixel electrodes of the respective pixel units of the row are charged.

Embodiment 3

[0055] This embodiment is basically the same as Embodiment 1, the difference is that in this embodiment, the n+1th main gate line Gn+1 is merged into the first main gate line G1, that is, Gn+1 and G1 are combined is a main gate line as G1, then the gate (or source) of the third transistor T3 in the nth gate line group is still connected to the second gate line in the nth gate line group, but the nth gate line group The source (or gate) of T3 in the line set should be connected to G1. Specifically, it may be connected to the first gate line or the second gate line in the first gate line group.

[0056] In this way, the control method in Embodiment 2 can also be used. In addition, one busbar line can be further reduced. For example, in an HVGA liquid crystal display, only 120 busbar lines need to be arranged on both sides of the display area, which improves the symmetry of the lines on both sides of the display area.

Abstract

The embodiment of the invention discloses an array substrate, a display unit and a control method thereof, belongs to the display technical field, and solves the technical problems that the H-line of a conventional narrow-frame liquid crystal display of a conventional grid drive circuit is poor, and the displaying effect is influenced. The array substrate comprises grid line groups and main grid lines, wherein, the number of the grid line groups is n, and the number of the main grid lines is n plus 1; each grid line group comprises a first grid line and a second grid line which are adjacent, a first transistor T1 is provided correspondingly to each first grid line, and a second transistor T2 and a switch element T3 are provided correspondingly to each second grid line; each first grid line and each second grid line in the grid line group i are connected with the main grid line i; a gate electrode of the T1 is connected with the first grid line, a source electrode is connected with a data cable, and a drain electrode is connected with a pixel electrode; the gate electrode of the T2 is connected with the T3 in a pixel unit, the source electrode is connected with the data cable, and the drain electrode is connected with the pixel electrode; in addition, one end of the T3 is connected with the main grid line i plus 1 and is used for controlling the switching-on and switching-off of the T2. The array substrate, the display unit and the control method thereof can be applied in the liquid crystal display.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to an array substrate, a display device and a control method thereof. Background technique [0002] With the continuous development of display technologies, liquid crystal displays (Liquid Crystal Display, LCD) have occupied a dominant position in the field of flat panel displays. The pixels in the liquid crystal display are arranged in an array, and each pixel is generally divided into three pixel units of red, green, and blue. Each pixel unit is jointly controlled by a gate line and a data line. [0003] The number of grid lines in a liquid crystal display is equal to the number of rows of pixels. For example, in a common HVGA (Half-size video Graphics Array, half-video graphics array) type liquid crystal display, the number of pixels is 480×320, and 480 grid lines need to be set. Wire. These gate lines are to be connected to the gate driver from the side of the dis...
