Abstract
The present application discloses a method for processing image data with enhanced grayscale level for a display panel. The method includes receiving image data with a maximum grayscale level up to (M+N)-bit. The method further includes dividing the image data of the (M+N)-bit to a first set of data including low-order part up to M-bit and a second set of data including high-order part up to N-bit. Additionally, the method includes reconstructing multiple sets of new image data up to N-bit based on the first set of data and the second set of data. Furthermore, the method includes forwarding the multiple sets of new image data to the driver circuit respectively in multiple divisional time periods and driving the display panel to display image using the multiple sets of new image data.
