Display device, image data processing apparatus and method

An image data processing apparatus, applied in a pixel matrix, each pixel in the pixel matrix comprising a first subpixel and a second subpixel located in a first subpixel row and a third subpixel located in a second subpixel row, each of the first subpixel row and second subpixel row being formed by first to third subpixels aligned repeatedly;

• wherein the image data processing apparatus comprises:
• an edge detecting module, configured to receive to-be-displayed image data in the pixel matrix, and perform edge detection on the to-be-displayed image data to acquire edge pixels located at an edge of a predetermined type;
• a subpixel selecting module, configured to judge whether the first and second subpixels in the edge pixels are located on an even more outer side at the edge of the predetermined type relative to the third subpixel, and select the first and second subpixels located on the even more outer side at the edge of the predetermined type relative to the third subpixel as to-be-adjusted subpixels;
• a luminance attenuating module, configured to perform luminance attenuation on the to-be-adjusted subpixels according to a predetermined luminance attenuation coefficient, to obtain to-be-transmitted image data;
• and
• a data transmitting module, configured to transmit the to-be-transmitted image data to a source driver.
