Problems solved by technology

From the perspective of panel design, the increase in resolution will increase the fan-out area of ​​scan lines and data lines, which will reduce the configurable space of the panel; on the other hand, it will make each line The layout range of the signal traces becomes smaller, which leads to an increase in impedance and affects the quality of the display screen

[0035] FIG. 1 is a structural diagram of a liquid crystal panel according to a first embodiment of the present invention. Please refer to FIG. 1, the liquid crystal panel 110 has a plurality of scanning lines (such as SL1-SL4), and each scanning line corresponds to a plurality of pixels (such as 11-18), and the front end of each scanning line is passed through a switch (such as SW1, SW3, SW5, SW7) are coupled to the scan end, and the rear end of the scan line is coupled to the connection line CL via another switch (such as SW2, SW4, SW6, SW8). The gate drivers 120 , 121 are coupled to the scanning terminals G1 ˜ Gn on the liquid crystal panel 110 , and cooperate with the control signals CLK1 , CLK2 to drive the scanning lines (eg SL1 ˜ SL4 ). In this embodiment, the switches (such as SW1 , SW3 , SW5 , SW7 ) are, for example, thin film transistors (Thin Film Transistor).

[0036] In the liquid crystal panel 110 of this embodiment, every two scanning lines (such as SL1, SL2) ar...

[0045] From another point of view, the present invention can summarize a driving method suitable for the above-mentioned liquid crystal panel, please refer to FIG. 3 , which is a flowchart of a driving method for driving a liquid crystal panel according to a second embodiment of the present invention. Wherein, the liquid crystal panel includes a first scan line and a second scan line, and the first scan line is coupled between a first switch and a second switch, and the second scan line is coupled to a third switch and a fourth switch. This driving method is described as follows: During the same scanning period, the driving method has four steps. In step S301, the driving circuit outputs a scanning signal, and transmits the scanning signal to the other end of the first switch and the third switch in the liquid crystal panel. . In step S302, the driving circuit outputs a logic low voltage, and transmits the logic low voltage to the other end of the second switch and the fourth...

Abstract

The invention discloses a liquid crystal panel which is provided with a plurality of scanning lines, and every scanning line corresponds to a plurality of pixels. The liquid crystal panel comprises a first switch, a second switch, a third switch, a fourth switch and a connecting line, wherein the first switch is coupled between the first scanning line and a first scanning end, the second switch is coupled between the other end of the first scanning line and the connection wire, the third switch is coupled between the second scanning line and the first scanning end, the fourth switch is coupled between the other end of the second scanning line and the connection wire, and the connecting line is coupled to the other end of the second switch and the fourth switch, outputting a logic low voltage. The first, second, third, and fourth switches all are film transistors. The design of the liquid crystal panel can reduce the using quantity of the grid electrode-driving integrated circuits, and enables the panel to have more configuring spaces for utilization.

Description

technical field [0001] The present invention relates to a liquid crystal panel and its driving method, and in particular to a liquid crystal panel and its driving method which can reduce the number of gate driving ICs. Background technique [0002] Generally speaking, in the traditional technology, the scanning lines of the display panel and the scanning signal output terminals of the gate driver IC are one-to-one. Therefore, once the scanning lines increase, 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 increase in resolution w...
