Abstract
A brightness adjustment method for a display is disclosed. The brightness adjustment method includes determining a first pulse width modulation (PWM) value according to an average picture level (APL) of an image signal; converting the first pulse width modulation value into a second pulse width modulation value according to a converting curve corresponding to a brightness value of the display; and controlling the display to present the image signal with the second pulse width modulation value under the brightness value.
Claims12
A brightness adjustment method for a display, comprising:
- determining a first pulse width modulation value according to an average picture level of an image signal;
- converting the first pulse width modulation value into a second pulse width modulation value according to a converting curve corresponding to a brightness value of the display;
- and
- controlling the display to present the image signal with the second pulse width modulation value under the brightness value.
A driving device for a display, comprising:
- a processor;
- and
- a storage device, coupled to the processor, for storing a program code, wherein the program code is configured to instruct the processor to determine a first pulse width modulation value according to an average picture level of an image signal, convert the first pulse width modulation value into a second pulse width modulation value according to a converting curve corresponding to a brightness value of the display, and control the display to present the image signal with the second pulse width modulation value under the brightness value.
