Abstract: A display device includes a display panel including a plurality of gate lines and a plurality of data lines, the plurality of gate lines intersecting and being insulated with the plurality of data lines, the display panel further including a plurality of sub-pixels arranged in an array, and the plurality of gate lines and the plurality of data lines defining areas where the sub-pixels are located; a gate driver electrically connected to the plurality of gate lines in the display panel; and a source driver bound to the display panel and electrically connected to the plurality of data lines in the display panel, the source driver being configured to set data transmission start time for respective data lines so that effective charging time of respective sub-pixels formed by the plurality of data lines and a same gate line is same.

Abstract: An image compression method comprises: performing feature extraction on the target image to obtain a first feature map comprising a plurality of channels; grouping the channels of the first feature map to obtain a plurality of second feature maps; performing spatial context feature extraction on the second feature maps to determine first spatial redundancy features corresponding to the second feature maps; and performing channel context feature extraction on the second feature maps to determine first channel redundancy features corresponding to the second feature maps; determining compression information corresponding to each of the second feature maps based on a first spatial redundancy feature and a first channel redundancy feature corresponding to each of the second feature maps and thus determining first compressed data corresponding to the target image, and performing deep compression processing based on the first feature map to determine second compressed data corresponding to the target image.

Abstract: A display panel, including a drive circuit, where the drive circuit is at least used to drive the display panel to display obtained display data. The drive circuit includes a shift register, a data buffer and a first control circuit; the shift register is used to output display data of each sub-pixel according to a preset timing sequence; the data buffer at least includes a first cache module composed of N repeat units; a repeat unit includes at least one cache unit, the cache unit is connected to the shift register, and two cache units at a same position in the k-th repeat unit and the (k+1)-th repeat unit are multiplexed with a same clock signal terminal; the cache unit is used to be turned on in response to an output signal from the clock signal terminal connected to the cache unit, to cache the received display data.

Abstract: Provided are a method for driving a display panel, and a display device. When switching from a first picture to a second picture is performed and the second picture is displayed in at least two consecutive display frames, display data of the second picture is received in the current display frame of the second picture; whether the second picture is a poor picture is determined according to the display data and a poor picture determining condition; and when the second picture is a poor picture, a display panel is controlled to perform scanning driving every at least one row of sub-pixels, and in two rows of sub-pixels subjected to scanning driving, when the first row of sub-pixels has been driven and the second row of sub-pixels is being driven, display data corresponding to the second row of sub-pixels is loaded to a data line connected to the second row.

Abstract: The present invention discloses an application of litchi chinensis pericarp extract mainly composed of polymer polyphenols in preparation of ?-amylase inhibitor, which belongs to the technical field of biology. The litchi chinensis pericarp extract mainly composed of polymer polyphenols disclosed by the present invention has a very good inhibitory effect on ?-amylase, whereas ?-amylase is applied in weight and blood glucose reduction, biological pesticides, dental caries prevention, and osteoporosis prevention and treatment.

Abstract: A cosmetic instrument capable of reading a memory card includes a first housing; a second housing, assembled with the first housing to cooperatively form a shell having a chamber; a massage head mounted on a first end of the shell, the massage head extending into the chamber; a control panel comprising a display panel, the control panel being mounted on the shell beside the massage head; a micro controller unit and a drive unit positioned in the chamber and electrically connected with each other, the micro controller unit being electrically connected to the control panel and the display panel. The first housing and the seconding housing define a card insertion hole. The micro controller unit is configured to read information of a memory card inserted into the card insertion hole and generates a result. The display panel displays the result to remind the user to operate the cosmetic instrument.
