In a method of a touch panel determining multi-touch, the touch panel can determine if a sensing channel having a local minimum of a sensing value is the last sensing channel having the sensing value, or determine if sensing channels having the sensing value larger than a threshold generated according to a maximum are successive sensing channels, so as to determine the number of touch points on the touch panel. In addition, the touch panel can find a first local maximum and a second local maximum from the sensing values of the sensing channels, and compare the first local maximum and the second local maximum with a first reference and a second reference, so as to confirm the number of touch points on the touch panel.

The present disclosure provides a system and method for repairing poor display in a liquid crystal display panel. The system comprises: an image acquisition device for acquiring image data of the liquid crystal display panel containing poor display areas; a lossless compression module for calculating difference values between the acquired image data to perform lossless compression; a storage for storing data after the lossless compression; and a Mura repair module for decompressing the data in the storage, and repairing Mura of the decompressed original image data to generate information feed to the liquid crystal display panel. In the present invention, the acquired image data are stored in the storage, after being subjected to the lossless compression/decompression, and goes through the Mura repair, and then is output to the panel, such that both the capacity of the storage and the cost can be reduced without degrading the effect of De-Mura processing.

The present invention discloses a display system and a display control method thereof. The display system comprises a display screen, a display controller, and a timing controller. The display controller comprises a 2D to 3D converter for converting image data with 2D format into converted image data with 3D format, and an encoding module for converting the converted image data with 3D format or first image data with 3D format into “2D image plus depth diagram” format data. The timing controller comprises a decoding module for converting the “2D image plus depth diagram” format data into decoded image data with 3D format or scaling the “2D image plus depth diagram” format data into scaled image data with 2D format suitable for outputting on the display screen. Accordingly, the present invention can reduce the required transmission line in order to reduce the production cost.
