Abstract

The invention provides a voltage supply method, a voltage supply device, a display device and electronic equipment. The voltage supply method is applied to the pixel circuit, the pixel circuit comprises a driving unit, a first end of the driving unit is electrically connected with a driving voltage end, and a second end of the driving unit is electrically connected with a light-emitting element; the voltage supply method comprises the following steps: dividing the display time of a frame of picture into N display time periods, wherein N is an integer greater than 1; in the nth display time period, providing the nth driving voltage for the driving voltage end, wherein the nth display time period corresponds to the nth driving voltage, n is a positive integer smaller than or equal to N, andthe driving voltages corresponding to the at least two display time periods are different from each other. According to the invention, the light-emitting brightness of the light-emitting element can be accurately adjusted.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a voltage supply method, a voltage supply device, a display device and electronic equipment. Background technique [0002] The image quality of a display depends on the precision of the pixel circuit's light-emitting brightness control. The control of the light emitting brightness of the pixel circuit can be realized by adjusting the data voltage and the driving voltage, and then adjusting the current flowing through the light emitting element. The luminous brightness of the light-emitting element has a linear relationship with the flowing current. In order to realize precise control of the luminous brightness of the pixel circuit, it is necessary to precisely control the current flowing through the light-emitting element. However, the relationship between the current flowing through the light-emitting element and the driving voltage is a power exponent, and a small change in t...
