Problems solved by technology

However, this not only increases the complexity of panel drive circuit design, but also requires multiple sets of signals to control
[0003] In addition, because the drive circuit design is more complex, the use of electronic components is bound to increase, which increases the overall area of ​​the circuit and power consumption, and the signal noise also remains high with the complexity of the circuit

Abstract

A display circuit and a driving circuit thereof. The driving circuit includes a control unit, a start unit, two output units, and a shift registor. The control unit outputs two control signals. The start unit is provided with an output node for outputting a start signal. The first output unit is connected to the output node and the control unit and comprises a first control switch. When the first control switch conducts the circuit according to the first control signal, the first output unit outputs a first scanning pulse. The second output unit is connected to the output node and the control unit and comprises a second control switch. When the second control switch conducts the circuit according to the second control signal, the second output unit outputs a second scanning pulse. The shift registor is connected to the control unit and outputs a clock signal according to one of the control signals. The first control signal and the second control signal conducts the two control switches through time sharing.

Description

technical field [0001] The disclosed document relates to a display panel, in particular to a display panel with a dual-output driving circuit. Background technique [0002] In order to maintain the picture quality of high-resolution high-end display panels, a frame rate (picture update rate) such as 120Hz is usually used, but this makes the charging / discharging update time of the storage capacitor inside the display panel insufficient, resulting in the picture may not be effective presented. In order to solve this problem, a gate interlace half high frame driving (gate interlace half high framerate) technology is proposed. In order to realize this high-level technology and reduce the time delay of charging and discharging the pixel electrodes of the panel, the display panel driving architecture must have two sets of driving circuits on both sides of the panel to drive odd-numbered scanning lines and even-numbered scanning lines respectively. However, this not only increase...
