Abstract: The present invention provides a display driving circuit and a liquid crystal display panel with adding a first AND gate (AND1), a second AND gate (AND2) and a third AND gate (AND3). Two input ends of each of the three gates receives a branch control signal and a conditioning signal (BURR), and the conditioning signal (BURR) first performs several high and low voltage level conversions and then maintains the high voltage level, respectively in the high voltage level durations of the respective branch control signals to make the signal outputted by the output end of the first AND gate, the signal outputted by the output end of the second AND gate and the signal outputted by the output end of the third AND gate first perform several high and low voltage level conversions and then maintain the high voltage level.

Abstract: A touch display panel includes touch detection electrodes and fingerprint recognition electrodes that share a common electrode layer. The pixel electrodes function as a drive pixel layer to induce capacitive coupling with respect to the fingerprint recognition electrodes, based on which operations of displaying, touch detection, and fingerprint recognition are carried out in a time sharing manner. The touch display panel requires no integration of separately made fingerprint recognition device and a touch display panel, and fingerprint detection can be realized with an existing layered structure of the touch display panel to thereby effectively save the manufacturing cost of the touch display device and achieve an effect of integrating a fingerprint recognition device and a touch display panel. A touch display device that includes the touch display panel is also provided.

Abstract: The invention provides a display assembly and a mobile terminal. The display assembly includes a display and a system chip. The display includes a display body and a drive chip mounted on the display body. The system chip includes a data analyzing module and a data sending module. The drive chip includes a receiving module and a processing module. The data analyzing module receives image data and analyzes the image data to obtain high bit data of the image data when the mobile terminal is in an idle status. The data sending module sends the high bit data of the image data to the receiving module. The processing module receives the high bit data of the image data sent by the receiving module and sends the high bit data of the image data to the display body to display.
