Abstract: Disclosed is a display module, comprising an array substrate, a driving chip, a pad set and a flexible printed circuit. The array substrate has a top surface and a bottom surface which are oppositely disposed and a through hole penetrating through the top surface to the bottom surface. A conductive material is filled in the through hole to form a conductive portion. The driving chip is arranged at the top surface. A portion of pins of the driving chip is electrically connected to the conductive portion. The pad set is arranged at the bottom surface and right faced to the driving chip. The pad set is electrically connected to the conductive portion. The flexible printed circuit is bonded to the pad set. The screen occupation ratio of the display module of the present application is larger. A terminal is further disclosed.

Abstract: The present disclosure relates to a driving method and a driving device of display panels. The driving method includes: obtaining three-color sub-pixel data of each of pixels of a current image; obtaining a saturation value and a Chroma value corresponding to each of the pixels; determining if the saturation value corresponding to each of the pixels is within a predetermined range; obtaining a white-grayscale-added value in accordance with the Chroma value corresponding to the pixel, adopting the white-grayscale-added value as a white grayscale value of the four-color sub-pixel data corresponding to the pixel, and outputting the white grayscale value to the display panel upon determining the saturation value corresponding to the pixel is within the predetermined range. In this way, the brightness of the pure-color image displayed on the display panel may be enhanced, and there is no darker issue when the pure-color image is displayed.

Abstract: The present disclosure relates to a driving method and a driving device of touch display panels, and a touch display. The driving method includes: detecting a voltage potential of at least one pixel electrode within the areas of the touch display panel corresponding to different touch scanning partitions, negating the voltage potential, overlapping the negated voltage potential and feed-backed touch pulse signals, and adopting overlapped signals to be the detected touch pulse signals. With the configuration of the touch scanning partitions, the voltage potentials of the pixel electrodes within each of the areas are adopted to respectively adjust the feed-backed touch pulse signals such that the display scanning and the touch scanning can be conducted simultaneously. The detection precision of the touch pulse signals may be enhanced without affecting the display performance.

Abstract: The present disclosure discloses a liquid crystal display driving device, including a time sequence controller, a data and scan drivers, a liquid display panel and a programmable gamma circuit connected to the data driver. The time sequence controller is respectively connected to the data and scan drivers. The data driver coverts an image data to an analog voltage. The programmable gamma circuit outputs a reference voltage to the data driver and used to assign the reference voltage in real time. The reference voltage corrects the analog voltage so the data driver outputs a gray-level voltage to a liquid crystal unit opened by the scan driver to display an image frame or a black frame. It overcome a problem of overlapping a left-eye and right-eye image frames and at the same time greatly decreases a power consumption of a system. The present disclosure also discloses a liquid crystal display driving method.

Abstract: The present invention discloses a display device capable of performing black frame insertion. The gamma circuit comprises an either-or multiplex selector. The input data of one input end of the selector is a VCOM voltage outputted by the gamma circuit, and the input data of the other input end of the selector is a voltage converted from a predetermined value after digital to analog conversion stored in a multi time programmable memory of the gamma circuit. As the selector selects the VCOM voltage outputted by the gamma circuit under control of the control port, the outputted VCOM voltage is amplified by an operational amplifier in the gamma circuit and then outputted to the source driving circuit to be a first gamma reference voltage which is required as the source driving circuit performs digital to analog conversion.
