Control method and control device of display power supply, storage medium and electronic apparatus

A control device of display power supply, applied to a thin film transistor display screen comprising a drive IC and a screen body, the drive IC controlling the screen body to display a corresponding image, and the screen body controlling a pixel via a thin film transistor;

• the control device comprising:
• a power-up control circuit controlling a power supply of the drive IC to power up according to a set rule after receiving a start signal for reducing a probability of abnormality in a voltage outputted by the drive IC;
• and
• a normal power supply supplying power continuously and normally to the drive IC.

An electronic device, comprising a power IC, a drive IC, and a screen body;

• the power IC comprising a memory in which a program being stored, wherein when the program is executed by the processor, causing the processor to perform:
• controlling a power supply of the drive IC to power up according to a set rule after receiving a start signal for reducing a probability of abnormality in a voltage outputted by the drive IC;
• and
• supplying power continuously and normally to the drive IC.
