  • Publication number: 20210271304
    Abstract: A system and method for powering up a portable information handling system based on a position of a kickstand and a position of a keyboard relative to a chassis. When a kickstand is opened, a power control system determines if a keyboard is attached and opened. If the keyboard is not attached and the kickstand is opened, the power control system initiates powering up the portable information handling system. If the keyboard is attached and closed, the portable information handling system is not powered up. If the keyboard is attached and opened, the power control system initiates powering up the portable information handling system. If the kickstand is opened and the keyboard is opened, the power control system initiates powering up the portable information handling system.

  • Patent number: 10872547
    Abstract: A gate driver with reduced voltage fluctuations driving a display device generates pulse signals shifted in a specified phase. The gate driver includes connected unit circuits. Each unit circuit includes an output terminal, input and output transistors, and a holding module. First and second control signals, alternating oppositely between high and low states, govern the two transistors. The input transistor is controlled by a first control signal and outputs a high level voltage to a first node based on a trigger signal. The output transistor outputs the shifted pulse signal synchronously with a clock control signal, based on the high level voltage of the first node. Initially, the trigger signal is low and the first and second control signals are high. The holding module outputs the low level voltage to the output terminal based on the first control signal and the second control signal.

    Abstract: A display device comprising thin film transistor array substrate includes scan lines, data lines, pixel units, and a source driver. Each pair of scan lines extends in a first direction and data lines extend in a second intersecting direction. Of the first and second sub-pixels in each pixel unit, the first sub-pixel connects to the first scan line, and the second sub-pixel connects to the second scan line. The first and second sub-pixels also straddle and connect to one data line. Source driver supplies the data lines with voltages and the voltage to the first sub-pixel is greater than the voltage to the second sub-pixel. This configuration avoids appearance of stripes on the display arising from charging rates of adjacent pixel columns not being the same.
