Abstract

Disclosed are a driving method and an electronic device. The method is applied to the electronic device. The electronic device includes a motherboard, a first storage unit, a display control chip and a drive controller. Identification information of each type of flat-panel displays in M types of flat-panel displays, types of flat-panel displays and a corresponding relation of driving-current information and driving-voltage information are stored in the first storage unit, wherein M is an integer larger than or equal to 2. The method includes the following steps: the display control chip obtains first identification information of a first flat-panel display and determines that the first flat-panel display belongs to a first type and determines a first driving current value and a first driving voltage value of the first flat-panel display which belongs to the first type on the basis of the first identification information and the corresponding relation and sends the first driving current value and the first driving voltage value to the drive controller; and the drive controller outputs a first driving current and a first driving voltage.

Description

technical field [0001] The invention relates to the field of driving, in particular to a driving method and electronic equipment. Background technique [0002] With the development of display technology, more and more manufacturers are involved in the production and sales of flat-panel displays. Since each manufacturer adopts different technologies, the resulting flat-panel displays are also different. , without being restricted by one or several flat-panel display manufacturers, the products of several flat-panel display manufacturers are generally selected, and the parameters of the display panel backlight modules of different manufacturers and different models are very different, and then the driver of the display is manufactured. Sometimes you will face the problem of how to drive many different types of flat panel displays. [0003] For this reason, the method that prior art adopts is as follows: [0004] Different drivers are designed for the backlight characteristic...
