Frame rate-convertible active matrix display

A dithering and directional modulation-based frame rate conversion apparatus, comprising:

• a directional delta modulation generator configured to receive a plurality of input color data representing a plurality of input color components of an input pixel color and generate a plurality of modulated data for the plurality of input color data respectively;
• and
• a plurality of dithering modules configured to perform K-bit dithering conversion on the plurality of input color data respectively to generate a plurality of output color data for representing a plurality of output color components of an output pixel color with a color depth of K bits per component, where K is an integer equal to or great than 1, each of the dithering modules comprising:
• a respective residue line buffer configured to track a residual error in dithering conversion to generate a respective residual data;
• a respective adapter configured to receive a respective input color data, a respective modulated data from the directional delta modulation generator and the respective residual data, and adapt the respective input color data to generate a respective adapted color data by adding the respective input color data with the respective modulated data and the respective residual data;
• and
• a respective dithering engine configured to receive the respective adapted color data and compare the respective adapted color data against a (2K−1) number of dithering threshold values to generate a respective output color data with 2K possible color levels.
