Methods, systems, and devices are described herein for encoding, decoding, and otherwise processing in hardware and/or software a high dynamic range (HDR) color data structure. In one example, a method for encoding pixel data may include receiving pixel data comprising a red, green, and blue (RGB) value. The method may further include transforming the received pixel data to an intermediate color space data, such as transformed CIE AYB space data. The method may further include compressing the intermediate color space data into less than 64 bits, such as 32 bits. In some aspects, the 32 bits may be divided into luminance information and chrominance information, including, for example, 14 bits representing a floating point luminance value, and 9 bits each representing two fixed point chrominance channel values.

A driving circuit includes a data comparator, a data processor and a driver. The data comparator determines whether a second row of image data is the same with a previous first row of image data. If YES, the data comparator outputs a disable signal, then the data processor stops operating according to the disable signal and outputs an indicating signal, and the driver outputs a previous first row of output image data to a panel according to the indicating signal; if NO, the data comparator outputs the second row of image data to replace the previous first row of image data, then the data processor processes the second row of image data to generate a second row of output image data, and the driver outputs the second row of output image data to the panel to replace the previous first row of output image data.
