Problems solved by technology
From the perspective of panel design, the increase in resolution will increase the fan-out range of scan lines and data lines, which will reduce the configurable space of the panel; on the other hand, it will make the layout of each signal line The range becomes smaller, which leads to an increase in impedance and affects the quality of the displayed picture

Embodiment Construction
[0019] Please refer to figure 1 , figure 1 is a schematic diagram of a liquid crystal panel according to the first embodiment of the present invention. According to the first specific embodiment, the liquid crystal panel 100 of the present invention includes a plurality of gate drivers (such as gate drivers 110, 112), a plurality of scanning lines (such as L1-L6), a plurality of switches (such as K1-K8), A control unit (not shown) and a connection line Vg1. In this specific embodiment, the gate drivers 110, 112 have scanning terminals G1-Gn, and every three scanning lines (such as L1-L3) form a group, wherein any two scanning lines are such as the first scanning line L1, the second scanning line The front end of the scanning line L2 is coupled to the first scanning terminal G1 through the switches K1 and K2, the rear ends of the first scanning line L1 and the second scanning line L2 are coupled to the connection line Vg1 through the switches K2 and K4, and the third scanning...

The invention relates to a liquid crystal panel and a driving method thereof, and the liquid crystal panel comprises a gate driver, a first scanning line, a second scanning line, a third scanning line, a connecting line and a control unit. The gate driver comprises the first scanning end; the first scanning line and the second scanning line are respectively coupled from a first switch to a fourthswitch, and the other end of the first switch, the other end of a third switch and one end of the third scanning line are coupled with the first scanning end; the connecting line is coupled with the other end of a second switch and the other end of the fourth switch, and the connecting line outputs logic low voltage; and the control unit is used for respectively outputting a first control signal to a fourth control signal, thereby controlling the conduction and the closing of the first switch to the fourth switch. The liquid crystal panel and the driving method can lead the same scanning signal to sequentially drive the three scanning lines, further reduce the number of the gate drivers, reduce the working frequency of the gate driver, reduce the power consumption and increase the configuration space on the liquid crystal panel.
Description
technical field [0001] The invention relates to a liquid crystal panel and its driving method, and in particular relates to a liquid crystal panel and its driving method which can reduce the number and operating frequency of gate drivers. Background technique [0002] Generally speaking, in the traditional technology, the scan lines of the display panel and the scan signal output terminals of the gate driver (gate driver IC) are one-to-one. Therefore, once the scan lines are increased, the output terminals of the gate driver IC will also increase accordingly. With the increasing trend of the resolution of liquid crystal displays, the design of the display panel requires more gate driver ICs to drive more scan lines, thus increasing the cost of the driver ICs. [0003] However, in order to meet consumers' preferences in order to be thin, light and small, the liquid crystal display has compressed the configuration space in the panel. From the perspective of panel design, the...
