Abstract: A display device and a method for driving the display device are described, where the display device includes a plurality of pixel island groups, a plurality of lenses, a positioning module, and a gate driving chip. The plurality of pixel island groups are arranged in array, wherein each of the pixel island groups includes a plurality of pixel islands, and different pixel islands are able to be scanned in different scanning modes. The positioning module is configured to determine a gaze area and a non-gaze area according to gazed coordinates of human eye. The gate driving chip is configured to provide gate driving signals in a first driving manner to sub-pixel units in the gaze area, and provide gate driving signals simultaneously in a second driving manner to sub-pixel units in the non-gaze area during a scanning stage of the sub-pixel units in the non-gaze area.

Abstract: The present application provides an audio and video playing system, a playing method and a playing device. The system comprises: a display device; a directional sound output module configured to output a directional sound signal; a tracking element configured to monitor a target visual area and to monitor the target display area on the display screen; and a processor, connected with the directional sound output module and the tracking element respectively, and configured to acquire a first audio and video data to be output in the target display area, display image information of the first audio and video data in the target display area, and output sound information of the first audio and video data to the directional sound output module such that the directional sound output module output a directional sound signal towards the target visual area.

Abstract: Provided is a method for compensating a displayed picture in a display screen. The display screen includes a plurality of regions, each of the plurality of regions including a plurality of pixels; the method includes: determining transformation matrices corresponding to pixels in the plurality of regions based on texture complexities of pictures to be displayed in the plurality of regions; acquiring compensated grayscales by compensating grayscales of pixel points in the pictures to be displayed in the plurality of regions based on the transformation matrices corresponding to the pixels in the plurality of regions.

Abstract: A solderless battery pack is provided that includes a battery port, a protective plate, an upper end plate, a lower end plate, cell groups and a cell locking mechanism. The cell groups are arranged between the upper end plate and the lower end plate and include a cell installation bracket, cells and a PCB busbar. The cell locking mechanism includes a metal upper pressing plate, a metal lower pressing plate and a fastening long bolt that passes through the metal upper pressing plate, the metal lower pressing plate, the upper end plate, the lower end plate and the cell groups.

Abstract: The present disclosure provides an image compression method, including steps of: acquiring a human-eye fixation point on an original image, and determining a fixation region and a non-fixation region of the original image according to the human-eye fixation point; and compressing the non-fixation region, and generating a compressed image according to the fixation region and the compressed non-fixation region. The present disclosure also provides an image display method, an image compression apparatus, an image display apparatus, and a computer readable medium.

Abstract: Various techniques for offline record selection to avoid negatively impacting latency are described herein. In one embodiment, a method includes receiving a search query from a client device via a network and in response to the received search query, determining if the received search query corresponds to one or more records of offline content. The records of offline content are previously determined and prior to receiving the search query. In response to determining that the received search query corresponds to at least one record of offline content, the method includes retrieving and providing the at least one record of offline content to the client device via the network.

Abstract: Methods, systems, and computer program products are provided for information presentation. In one implementation, a method is provided. The method includes generating a message, identifying suggested content to be included with the message, suggesting one or more of the suggested content items to a user, receiving a user input with respect to the one or more suggested content items, and sending the message according to the user input including one or more selected content items of the one or more suggested content items.

Abstract: Systems and methods for delivering advertisements with a video. A video is received at a client device, and data identifying a frame of the video, and an advertisement associated with the frame of the video are identified. The video is displayed during a playback of the video on the client device, and it is determined from the data identifying the frame of the video that the frame of the video is displayed during the playback of the video. The advertisement and the frame of the video are displayed proximate to a display of the video in response to the determination.
