A display apparatus and a timing controller thereof is disclosed. The timing controller detects a size of an image by using image data, generates first output image data according to the size of the image, and generates second output image data by using the first output image data. The second output image data is generated according to a saturation value of the first output image data.

Display apparatus and timing controller thereof

The present embodiment relates to an apparatus and method for processing image data for driving a display panel, and more particularly, to an apparatus and method for flexibly changing brightness of each pixel based on a representative brightness value of each image.

Display processing apparatus and method for processing image data

The present disclosure discloses an IR drop compensation apparatus and method for a display panel and a display driving apparatus having an IR drop compensation function. The IR drop compensation apparatus may be configured to generate an IR drop weight based on a brightness value obtained by measuring brightness of a display panel and to adaptively adjust the IR drop weight.

IR drop compensation apparatus and method for display panel and display driving apparatus

The present disclosure allows reducing the variation of the luminance depending on the types of images and improving image quality by calculating a plurality of representative values, representing the luminance of pixels so that the types of images can be distinguished, calculating a weight using such representative values, and compensating image data according to the weight.

Device and method for processing image data for driving display panel

Disclosed are a digital gamma circuit capable of reducing a chip area and adjusting white color coordinates, and a source driver including the same. The digital gamma circuit may include a digital gamma algorithm for setting a gamma curve for each R, G, or B. Through the digital gamma algorithm, values of X-axis points of the gamma curve may be set, values of Y-axis points of the gamma curve corresponding to the values of the X-axis points may be set, and a value of at least one Y-axis point indicative of white among the values of the Y-axis points may be adjusted by adding an offset value thereto.

Digital gamma circuit and source driver including the same

The present disclosure relates to a device and a method for processing image data for driving a display panel. More particularly, it relates to a device and a method to vary the brightness of each pixel according to a representative brightness value of an image.

Image data processing device and method of processing image data based on a representative value of an image

The present invention generates overdriving image data by compressing and storing image data and comparing stored previous-period image data and current-period image data. The present invention controls a data voltage upward or downward through overdriving image data, thereby improving the reaction speed of a pixel.
