Method and apparatus for subpixel rendering

A device for subpixel rendering, comprising:

• a first signal converting unit configured to, for each of an array of pixels on a display panel, receive a first signal including a first set of components, and convert the first set of components of the first signal to a second set of components of the first signal, wherein the second set of components of the first signal include a first component representing a first attribute of the pixel and a second component representing a second attribute of the pixel, and the first component weighs more to human vision sensitivity, and the second component weighs less to human vision sensitivity and comprises a first sub-component and a second sub-component;
• a signal processing module configured to, for each pixel, modify the second set of components of the first signal to generate a second signal including a modified second set of components by reducing a bandwidth of native display data of the first cutoff sub-frequency, reducing a bandwidth of native display data of the second sub-component using a second cutoff sub-frequency, and reducing a bandwidth of native display data of the first component using a second cutoff frequency, the first cutoff sub-frequency and the second cutoff sub-frequency being different from each another and each being lower than the second cutoff frequency;
• a second signal converting unit configured to, for each pixel, convert the modified second set of components of the second signal to a modified first set of components of the second signal;
• and
• a subpixel rendering module configured to, for each pixel, generate a third signal based on the modified first set of components of the second signal for rendering subpixels corresponding to the pixel.
