Abstract: Graphics rendering systems and methods for rendering a 3D scene on a screen of a user device. 3D scene data representing a 3D scene is received by a CPU and processed through a graphics rendering pipeline in which graphics rendering instructions are executed by the CPU in a Single Instruction, Multiple Data (SIMD) approach, wherein multiple data elements of the SIMD approach are stored in and retrieved from an SVE register of the CPU. Pixel data resulting from the graphics rendering pipeline is stored in the frame buffer for output to the screen via a renderer.

Abstract: A method (200) and an apparatus (500) for compensating for brightness of a display panel (140), and a display device (100) are provided. The method (200) for compensating for brightness of a display panel (140) includes: timing a vertical blanking interval (Vblank) in a current frame on the display panel (140) (202); and determining, in response to that a timing time of the vertical blanking interval (Vblank) reaches a first threshold time, a first value used to perform first compensation on brightness of the display panel (140) during the vertical blanking interval (Vblank) in the current frame (204). According to the method (200) for compensating for brightness of a display panel (140), a brightness change caused by current leakage can be compensated for by adjusting a related analog voltage in a timely manner.

Abstract: The present invention discloses a data sending method and a communications device. The method includes: sensing, by a communications device, a carrier located in a first unlicensed frequency band, where the first unlicensed frequency band includes at least one carrier; and sending, by the communications device, data on a carrier whose channel state is sensed to be idle. The communications device senses a first carrier in the first unlicensed frequency band, and sends the data on the first carrier that is successfully sensed to be idle. Another communications device may also sense in the first unlicensed frequency band, and send data in the first unlicensed frequency band when sensing successfully. Therefore, users of different services may fairly contend and coexist in an unlicensed frequency band.
