Abstract: An In-cell type touch display is provided in the present application. The display panel of the In-cell type touch display has a plurality of multiplexing modules corresponding to the multi-column touch sensing electrodes; each of the plurality of multiplexed modules includes a plurality of thin film transistors corresponding to the plurality of touch sensing electrodes corresponding to a column of touch sensing electrodes, respectively. The drains of the plurality of thin film transistors in the same multiplexing module are electrically connected, and to electrically connected to the corresponding pins of the touch and display driver chip, gates of the thin film transistors corresponding to the same row of the touch sensing electrodes are electrically connected to the same control signal line; sources of each thin film transistor are electrically connected to the corresponding touch sensing electrodes through corresponding traces. The touch and display driver chip size can be reduced.

Abstract: A method of performing gamma correction for LCD panels includes: dividing the display area of a LCD panel to form n sub-areas of the display area; dividing all grey-scale images into n sets to form n sets of grey-scale images; displaying a first chosen grey-scale image of each set of grey-scale images on the corresponding sub-area of n sub-areas concurrently; detecting the brightness of the first chosen grey-scale image with a photosensor installed on the sub-area; examining if there is grey-scale image pending for detection in the set of grey scale images; extracting a gamma curve of the LCD panel; and correcting the gamma curve of the LCD panel.
