Abstract
A source driver providing an output image to a plurality of pixels and including a judgment unit, an image processing unit, and a digital-to-analog converter is disclosed. The judgment unit encodes a first input image to generate an encoded code and compares the encoded code with a preset code to generate a luminance controlling signal. The image processing unit processes an image signal by an algorithm and outputs the processed result when the judgment unit asserts the luminance controlling signal. The image processing unit directly outputs the image signal when the judgment unit un-asserts the luminance controlling signal. The digital-to-analog converter transforms the output of the image processing unit and outputs the transformed result to the pixels.
Claims21
A source driver providing an output image to a plurality of pixels, comprising:
- a judgment unit encoding a first input image to generate an encoded code and comparing the encoded code with a preset code to generate a luminance controlling signal;
- an image processing unit processing an image signal by an algorithm and outputting the processed result when the judgment unit asserts the luminance controlling signal and directly outputting the image signal when the judgment unit un-asserts the luminance controlling signal;
- and
- a digital-to-analog converter transforming the output of the image processing unit and outputting the transformed result to the pixels.
An electronic system comprising:
- a power supply providing an operation voltage;
- and
- a display panel receiving the operation voltage, and comprising:
- a gate driver providing a plurality scan signals;
- a plurality of pixels receiving the scan signals;
- and
- a source driver providing an output signal to the pixels and comprising:
- a judgment unit encoding a first input image to generate an encoded code and comparing the encoded code with a preset code to generate a luminance controlling signal;
- an image processing unit processing an image signal by an algorithm and outputting the processed result when the judgment unit asserts the luminance controlling signal and directly outputting the image signal when the judgment unit un-asserts the luminance controlling signal;
