Display apparatuses, display panels, and methods of driving display panels

A method of driving a display panel, the display panel comprising:

• a base substrate;
• a pixel array disposed on the base substrate, and comprising one or more pixel groups each of which comprises a plurality of pixels;
• and
• a plurality of pixel driving chips disposed on the base substrate and configured to drive the pixel array to display, each of the pixel driving chips comprising a data signal terminal configured to receive data signals, and a control signal terminal configured to receive address signals, wherein the control signal terminal is further configured to receive a power supply voltage, and the address signals and the power supply voltage are distinguished from each other by amplitude of a signal received at the control signal terminal, wherein a control function is performed based on the address signals in response to the amplitude of the signal received at the control signal terminal being higher than a preset level, and a power supply function is performed in response to the amplitude of the signal received at the control signal terminal being lower than the preset level,
• wherein for each of the pixel groups, the plurality of pixels in the pixel group are connected to a common pixel driving chip, and
• wherein a display frame of the display panel comprises an address assignment stage and a data signal transmission stage,
• the method comprising:
• inputting a control signal to the control signal terminal and inputting a first data signal to the data signal terminal in the address assignment stage;
• and
• inputting a second data signal to the data signal terminal in the data signal transmission stage.
