Abstract
The present disclosure provides a brightness control method and a terminal device. The brightness control method includes: when confirming switching from a first mode to a second mode, adjusting a brightness of a first area of a screen of the terminal device from a first brightness to a second brightness; where the first brightness is the brightness of the first area in the first mode, and the first brightness is different from the second brightness; and, after entering the second mode, setting a brightness of a second area of the screen to be a third brightness. After entering the second mode, the brightness of the first area is the second brightness.
Claims20
A brightness control method applied to a terminal device, comprising:
- when confirming switching from a first mode to a second mode, adjusting a brightness of a first area of a screen of the terminal device from a first brightness to a second brightness;
- wherein the first brightness is the brightness of the first area in the first mode, and the first brightness is different from the second brightness;
- and
- after entering the second mode, setting a brightness of a second area of the screen to be a third brightness;
- wherein after entering the second mode, the brightness of the first area is the second brightness;
- wherein the terminal device is pre-configured with a first gamma data for the second mode;
- after entering the second mode, setting a brightness of a second area of the screen to be a third brightness, includes:
- after entering the second mode, setting a driving voltage of the second area to a first driving voltage and setting a driving voltage of the first area to a second driving voltage, and calling the first gamma data for displaying;
- wherein when the driving voltage of the second area is set to the first driving voltage and the first gamma data is called, the brightness of the second area is the third brightness;
- and when the driving voltage of the first area is set to the second driving voltage and the first gamma data is called, the brightness of the first area is the second brightness.
A terminal device comprising:
- a brightness adjustment circuit configured to, when confirming switching from a first mode to a second mode, adjust a brightness of a first area of a screen of the terminal device from a first brightness to a second brightness;
- wherein the first brightness is the brightness of the first area in the first mode, and the first brightness is different from the second brightness;
- wherein the brightness adjustment circuit is further configured to, after entering the second mode, set a brightness of a second area of the screen to be a third brightness;
- wherein after entering the second mode, the brightness of the first area is the second brightness;
- wherein the terminal device is pre-configured with a first gamma data for the second mode;
- the brightness adjustment circuit is further configured to, after entering the second mode, set a driving voltage of the second area to a first driving voltage and set a driving voltage of the first area to a second driving voltage, and call the first gamma data for displaying;
- when the driving voltage of the second area is set to the first driving voltage and the first gamma data is called, the brightness of the second area is the third brightness;
- when the driving voltage of the first area is set to the second driving voltage and the first gamma data is called, the brightness of the first area is the second brightness.
