摘要： The invention provides image display panels. The image display panel comprises a histogram generator, a tone slope generator, and an image transformer. The histogram generator receives an original image, counts the pixels of different gray levels to generate a histogram distribution of the original image, and compares the pixel counts at every gray level with a first threshold count to identify the peaks of the histogram distribution. The tone slope generator generates a tone slope based on the histogram distribution and peaks of the histogram distribution. The image transformer transforms the original image into a modified image based on the tone slope.

摘要： An overdrive system adaptable for a dynamic gamma generator is disclosed. A current gray-to-voltage converter (G/V) converts image data of a current frame from gray code to voltage level, and a previous gray-to-voltage converter (G/V) converts image data of a previous frame from gray code to voltage level. The voltage level of current frame and the voltage level of previous frame are inputted to an overdrive-voltage lookup table to retrieve an overdrive voltage level. Afterwards, a voltage-to-gray converter (V/G) converts the retrieved overdrive voltage level from voltage level back to gray code, resulting in an overdrive gray code. Accordingly, the overdrive gray code is compensated. Alternatively, the overdrive gray code is used to update an overdrive-gray-code lookup table, an output gray code of which is fed to the source driver.

摘要： A method of controlling backlight module, a backlight controller and a display device using the same are provided herein. First, an image having a plurality of regions is received, wherein the image is displayed by a plurality of color backlights which are provided from the backlight module. Next, a first average of a characteristic in a specific region of the image is calculated, wherein the specific region is one of the regions. According to the first average of the characteristic and a weight function, a characteristic weight is calculated. Next, one of the color backlights provided to the specific region is adjusted according to the characteristic weight. Therefore, adjusting the color backlights according to the image content can enhance the displaying quality of the image and adaptively reduce the artifacts perceived by human eyes in different images.
