Driving method, driving chip and display device of organic light-emitting display panel

Abstract

Embodiments of the present invention provide a driving method, a driving chip and a display device of an organic light-emitting display panel, which relate to the field of display technology and can improve brightness adjustment effects. The driving method includes: obtaining the target brightness; determining the corresponding gear of the target brightness in a plurality of gears, each gear has a first brightness interval, any two gears have different first brightness intervals, any There is no overlap between the two first brightness intervals, the first brightness interval of the gear corresponding to the target brightness includes the target brightness, and each gear has a gamma curve corresponding to the maximum value of the first brightness interval in the gear; In the gear corresponding to the target brightness, determine the duty cycle corresponding to the target brightness, and the maximum value of the first brightness interval of each gear corresponds to the same duty cycle; based on the Gamma curve in the gear corresponding to the target brightness and the target The duty cycle corresponding to the target brightness in the gear corresponding to the brightness drives the organic light emitting display panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a driving method of an organic light emitting display panel, a driving chip and a display device. Background technique [0002] At present, display technology has penetrated into every aspect of people's daily life, and correspondingly, more and more materials and technologies are used in display screens. Currently, mainstream display screens mainly include liquid crystal display panels and organic light emitting display panels. Among them, organic light-emitting display panels are more and more widely used due to their characteristics of high color saturation, high brightness, high contrast, fast response speed, and thinness. In order to make the displayed picture more in line with human visual perception, it is necessary to correct the picture according to the Gamma curve. [0003] However, the Gamma curve is a curve within a specific brightness range. After adjustin...

Problems solved by technology

[0003] However, the Gamma curve is a curve within a specific brightness range. After adjusting the brightness of the organic light-emitting display panel, the displayed picture will deviate from the preset Gamma curve, resulting in poor brightness adjustment effect.
