Abstract: A method for processing image data with reduced transmission bandwidth is provided. The method includes receiving a first set of data for image in a first resolution and receiving a center coordinate. The method further includes determining a high-definition region including an area and a boundary centered on the center coordinate. Additionally, the method includes rendering the first set of data based on the center coordinate and the area of the high-definition region to obtain a first subset of data. Furthermore, the method includes rendering a set of data compressed from the first set of data to obtain a second subset of data beyond the boundary. Moreover, the method includes transmitting a second set of image data to the display panel combining the first subset of data for display image in the first resolution and the second subset of data to display image in the second resolution.
