Abstract: The disclosure provides a display equipment, a brightness compensation device, and a brightness compensation method. The brightness compensation device includes a variable refresh rate (VRR) detection circuit and a control circuit. The VRR detection circuit and the control circuit receive a video stream from a video source device, and the video stream includes a VRR video frame. The VRR detection circuit detects a blanking period of the VRR video frame and generates a detection result. The control circuit outputs the frame data of the VRR video frame to the display device during the valid data period of the VRR video frame. The control circuit repeatedly outputs the frame data of the VRR video frame to the display device during the blanking period of the VRR video frame according to the detection result until the blanking period ends.

Abstract: A display apparatus that is suitable for a video wall and an operation method thereof are provided. The display apparatus includes a display panel, a memory circuit and a video processing circuit. The memory circuit is used for storing extended display identification data (EDID), and resolution information of the EDID may affect a resolution of a video frame signal of a video source. The video processing circuit transmits the video frame signal to a video output connector. Based on a video wall configuration parameter, the video processing circuit captures part or all of pixel data in the video frame signal to obtain a captured frame, and displays the captured frame on the display panel. Based on the video wall configuration parameter, the video processing circuit can adaptively change the resolution information of the EDID stored in the memory circuit.

Abstract: A separator is provided, which includes a porous polyolefin layer and a nano fiber web thereon, wherein the nano fiber web includes a plurality of nano fibers interwoven with each other. The nano fiber includes polyimide polymerized of diamine and dianhydride, wherein at least one of the diamine and the dianhydride is aliphatic or cycloaliphatic.

Abstract: The present invention is to provide an LED driver circuit which includes a capacitor and at least one LED respectively connected in parallel to a power source through a switch device, and a controller having an input end connected to a line between the switch device and the power source and being configured for detecting an input voltage applied to the LED. When the controller detected that the input voltage is unable to drive the LED to emit light, the controller activates the switch device to make only the connection between the capacitor and the at least one LED, such that the capacitor discharges a voltage stored therein to the at least one LED to continuously emit light. Since the driver circuit only needs a small-capacity, low-cost capacitor for increasing the light emission time of the at least one LED, the cost of the driver circuit can be lowered effectively.

Abstract: A common assembly structure of laser diode and PIN detector comprises a subassembly structure formed by connecting a laser diode to a submount made of low-capacitance material, and the sub-assembly structure is then implemented on a PIN detector. The so-called laser diode comprises a vertical cavity surface emitting laser (VCSEL) and an edge-emitting laser (EEL), wherein the EEL further comprises, for example, a Fabry-Perot Laser (F-P Laser) and a Distributed Feedback Bragg Laser. The common assembly structure of laser diode and PIN detector completely separates the anode and cathode of the semiconductor laser from the anode and cathode of the PIN detector thereby effectively reducing the parasitic capacitance effect derived from the PIN detector itself and the assembly structure, and is suitable for use in the high-speed laser driving circuits.
