Title:
DISPLAY DRIVING METHOD BASED ON INTEGRATED CIRCUIT, INTEGRATED CIRCUIT, DISPLAY SCREEN, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/062309
Kind Code:
A1
Abstract:
A display driving method based on multiple integrated circuits, a display driving method based on an integrated circuit, a display driving integrated circuit, a display screen driven by multiple integrated circuits, and a display device. In the display driving method based on multiple integrated circuits, the multiple integrated circuits comprise a first integrated circuit (3) and a second integrated circuit (4). The display driving method comprises: sending current boundary pixel data driven by the first integrated circuit (3) to the second integrated circuit (4); and performing, in the second integrated circuit (4), sub-pixel rendering calculation on the current boundary pixel data and current sub-pixel data which is stored in the second integrated circuit (4). By means of the display driving method based on multiple integrated circuits, at least missing values of the first column/row of pixel data of a second integrated circuit are supplemented on the basis of current boundary pixel data, and output data outputted to a driven region by the second integrated circuit is corrected, thereby preventing a dark line from appearing at the boundary between two adjacent driven regions.
