Abstract

The invention discloses an electrical appliance, a screen driving method thereof and device. The method comprises the following steps: after the electrical appliance is power-on, signals of at least one IO pin are read, and according to the signals of at least one IO pin, level combination signals are generated; according to the level combination signals, a corresponding screen identifier is acquired; and according to the corresponding screen identifier, a corresponding screen driver is loaded to drive screen display. In the method, through reading the level combination signals inputted by theIO pin and loading the corresponding screen driver, driving of multiple screens can be realized, and the technical problems of complex screen production and troublesome after-sales in the case of configuration without I2C can be solved, thus improving the production efficiency and the maintenance efficiency of the screen in the electrical appliance.

Description

technical field [0001] The present application relates to the technical field of electric appliances, in particular to a screen driving method of an electric appliance, a screen driving method of another electric appliance, a screen driving device of an electric appliance, a screen driving device of another electric appliance, an electric appliance, an electronic device and a non-transitory computer-readable storage medium. Background technique [0002] In electrical appliances with screens, various types of screens are usually supplied due to the relationship of the supply chain. Since different types of screens correspond to different drivers, it is necessary to identify the screen to configure the driver. [0003] However, for the screen of MIPI (Mobile Industry Processor Interface, mobile industry processor interface) that does not need I2C to configure, it is a direct output signal, so the method of separate firmware is generally used in related technologies, that is, ...
