Abstract

The invention discloses a driving voltage adjusting method and electronic equipment. The method is applied to the electronic equipment, the electronic equipment comprises a display module, and the method comprises the following steps: obtaining a target ripple value of a driving voltage of the display module of the electronic equipment in a target time period; and under the condition that the target ripple value is greater than the first ripple value, adjusting the driving voltage of the display module based on a first preset voltage difference threshold value and the input voltage of the boosting module for outputting the driving voltage so as to reduce the ripple value of the driving voltage of the display module. According to the embodiment of the invention, the splash screen problem ofthe display screen can be solved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a method for adjusting a driving voltage and an electronic device. Background technique [0002] Active-matrix organic light-emitting diode or active-matrix organic light-emitting diode (Active-Matrix Organic Light-Emitting Diode, AMOLED) display is a screen composed of self-luminous organic materials, which does not require a backlight. When an electric current is passed through the organic material, the pixels emit light by themselves. Compared with traditional liquid crystal panels, AMOLED displays are thinner and lighter, faster in response, higher in contrast, and wider in viewing angles, and are therefore widely used in mobile terminals. [0003] Because the driving voltage (ELVDD) of the AMOLED display module fluctuates, when the ELVDD of the display module fluctuates greatly, it will cause screen flickering.
