Embodiment Construction
[0023] In order to make the above objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0024] See figure 1 , which is a schematic structural diagram of a data encoding circuit based on sub-pixel downsampling provided by an embodiment of the present invention. The data encoding circuit 10 of this embodiment can process video source image data (for example, the output data of the graphics card of the host computer), which utilizes the advantages of parallel data processing by programmable logic devices, and is based on the sub-pixel downsampling technology and the anti-color error algorithm. The input high-resolution original image data is processed, and the output down-sampled image data can be used as the new video source image data of the flat panel display; thus, it can improve the system performance without changing...
