Abstract

The invention discloses a voltage adjusting method and electronic equipment. The method comprises the steps of obtaining a target brightness value currently displayed by a display pixel; determining avoltage added value according to the target brightness value; and adjusting the initial cathode voltage of the OLED device corresponding to the display pixel according to the voltage added value, andafter the voltage is adjusted, enabling the variation between the brightness value of the display pixel and the target brightness value to be within a preset range. The method can be applied to the electronic equipment, and the display quality of the display screen can be improved on the premise of reducing the power consumption of the display screen.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a voltage adjustment method and electronic equipment. Background technique [0002] With the development of the information age, mobile electronic devices such as mobile phones and tablet computers have increasingly become an indispensable part of people's lives. When consumers choose mobile products, in addition to factors such as performance and appearance, power consumption (standby time) is also an important consideration. As the display screen is one of the main power-consuming devices of mobile devices, its energy-saving technology has become an important subject of industry research. [0003] Active-matrix organic light-emitting diode (AMOLED), as a self-luminous device, has the advantages of fast response, vivid color and bendability, and is currently widely used in mobile phones, tablets, TVs and other displays field. refer to figure 1 , figure 1 It is a ...
