Display driving method and electronic device with enhanced electrostatic discharge protection

An electronic device, comprising a timing controller, a processor, a memory, and computer program instructions stored in the memory and executable by the processor to cause the processor to perform operations comprising:

• obtaining a voltage value of a power supply ground signal;
• in response to the voltage value of the power supply ground signal being greater than or equal to an electrostatic discharge voltage threshold, obtaining a data enable signal to be analyzed, and obtaining, from a timing controller, a previous frame data enable signal stored in the timing controller as a reference data enable signal;
• adjusting the data enable signal to be analyzed according to the reference data enable signal to obtain a current frame data enable signal;
• and
• writing the current frame data enable signal to the timing controller;
• wherein the data enable signal to be analyzed is an unadjusted data enable signal belonging to a current frame that has not been written into the timing controller;
• the reference data enable signal is the previous frame data enable signal of the data enable signal to be analyzed, the previous frame data enable signal having been verified to be free of interference signal and already written to and stored in the timing controller;
• the adjusting the data enable signal to be analyzed according to the reference data enable signal to obtain the current frame data enable signal comprises:
• counting a clock signal number of the data enable signal to be analyzed;
• extracting a first number of clock signals from the previous frame data enable signal as a first supplementary signal in response to the clock signal number being less than a preset number threshold, wherein the first number is a difference between the preset number threshold and the clock signal number;
• and
• supplementing the first supplementary signal to a head or a tail of the data enable signal to be analyzed to obtain the current frame data enable signal, wherein the first supplementary signal is a signal fragment of the previous frame data enable signal corresponding to the first number of clock signals.
