Shift register, gate line driving method, array substrate and display device

Abstract

The invention discloses a shift register, a gate line driving method, an array substrate and a display device, belonging to the field of displays. The shift register includes: a plurality of shift register units, which are set in one-to-one correspondence with the gate lines on the array substrate; a control unit for controlling the signals output by each shift register unit to each gate line , to control the opening and closing of each row of gate lines, so that the display area has at least one of a high-resolution area and a low-resolution area; in the low-resolution area, the control unit controls at least two adjacent gate lines to be turned on and off synchronously closure. When displaying in a low-resolution area, at least two gate lines are scanned at the same time, and the source driver writes the same data signal to the at least two gate lines, which reduces the change of the data signal, reduces the power consumption of the source driver, and reduces The overall power consumption of the display panel is reduced, and the problem of a sharp increase in power consumption of the existing high-resolution display panel due to the increase in the number of scanning lines is solved.

Description

Technical field [0001] The invention relates to the field of displays, in particular to a shift register, a gate line driving method, an array substrate and a display device. Background technique [0002] When the display panel displays images, a shift register (that is, a gate drive circuit) needs to be used to scan the pixel unit. The shift register includes a plurality of shift register units, and each shift register unit corresponds to a row of pixel units. The multiple shift register units realize the progressive scanning and driving of each row of pixel units in the display panel to display images. [0003] As the resolution of the display panel increases, the number of rows of pixel units in the display panel is increasing. For example, the number of rows of pixel units in a 4K display panel is 2160, and the number of rows of pixel units in an 8K display panel is even higher. 4320. Due to the increase in the number of rows of pixel units in the display panel, the power con...
