Shift register, display panel, and display drive method

A display panel, comprising:

• a display array, including a sub-pixel for picture display;
• a pixel circuit connected to the sub-pixel, configured to generate a drive current according to a scan signal to control the sub-pixel to perform light-emitting display;
• and
• a first scan circuit, wherein the first scan circuit includes a shift register including:
• an input module, configured to output a first control signal according to an input signal;
• a pull-down control module, configured to control a potential of a first node according to a first clock signal, a high-level signal, a low-level signal, and the first control signal;
• a pull-up control module, configured to control a potential of a second node according to the first clock signal, a second clock signal, the high-level signal, and the first control signal;
• a maintaining module, configured to pull down the potential of the first node according to the input signal, the first clock signal, the second clock signal, and the low-level signal;
• a pull-down output module, configured to control an output terminal of the shift register to output the low-level signal according to the potential of the first node;
• and a pull-up output module, configured to control the output terminal of the shift register to output the high-level signal according to the potential of the second node;
• wherein the shift register is connected to the pixel circuit and configured to provide the pixel circuit with the scan signal.

A display drive method of a display panel, wherein the display panel includes a sub-pixel and a pixel circuit connected to the sub-pixel, the method comprising:

• outputting a scan signal through a shift register, wherein the shift register includes:
• an input module, configured to output a first control signal according to an input signal;
• a pull-down control module, configured to control a potential of a first node according to a first clock signal, a high-level signal, a low-level signal, and the first control signal;
• a pull-up control module, configured to control a potential of a second node according to the first clock signal, a second clock signal, the high-level signal, and the first control signal;
• a maintaining module, configured to pull down the potential of the first node according to the input signal, the first clock signal, the second clock signal, and the low-level signal;
• a pull-down output module, configured to control an output terminal of the shift register to output the low-level signal according to the potential of the first node;
• and
• a pull-up output module, configured to control the output terminal of the shift register to output the high-level signal according to the potential of the second node;
• and
• controlling the pixel circuit to generate a drive current according to the scan signal, thereby controlling the sub-pixel to perform light-emitting display.
