Abstract
Embodiments of the present disclosure provide a device and a method for adjusting brightness of a display device. In the method for adjusting brightness of the display device, a first voltage data is applied to the display device when a peak brightness condition is met, or a second voltage data is applied to the display device when the peak brightness condition is not met, enabling the first voltage data greater than the second voltage data to be applied to the display device when the peak brightness condition is met, thus increasing the brightness when the display device emits light to display an image to be displayed and improving contrast.
Claims16
A method for adjusting brightness of a display device, comprising following steps:
- obtaining brightness information of an image to be displayed by the display device;
- determining whether a peak brightness condition is met according to the brightness information of the image to be displayed by the display device;
- and
- applying a first voltage data to the display device when the peak brightness condition is met, or applying a second voltage data to the display device when the peak brightness condition is not met, wherein the first voltage data is greater than the second voltage data;
- wherein the step of obtaining the brightness information of the image to be displayed by the display device comprises:
- obtaining a first light-emitting area of the display device;
- obtaining a second light-emitting area of the image to be displayed by the display device;
- obtaining a first data by dividing the second light-emitting area by the first light-emitting area;
- and
- using the first data as the brightness information of the image to be displayed by the display device;
- wherein the brightness information of the image to be displayed by the display device is a ratio of the second light-emitting area to the first light-emitting area.
A display device, comprising:
- a processor;
- a memory;
- and
- instructions stored in the memory and configured to be executed by the processor to perform a method, the method comprising following steps:
- obtaining brightness information of an image to be displayed by the display device;
- determining whether a peak brightness condition is met according to the brightness information of the image to be displayed by the display device;
- and
- applying a first voltage data to the display device when the peak brightness condition is met, or applying a second voltage data to the display device when the peak brightness condition is not met, wherein the first voltage data is greater than the second voltage data;
- wherein the step of obtaining the brightness information of the image to be displayed by the display device comprises:
- obtaining a first light-emitting area of the display device;
- obtaining a second light-emitting area of the image to be displayed by the display device;
- obtaining a first data by dividing the second light-emitting area by the first light-emitting area;
- and
- using the first data as the brightness information of the image to be displayed by the display device;
- wherein the brightness information of the image to be displayed by the display device is a ratio of the second light-emitting area to the first light-emitting area.
