  • Patent number: 10777111
    Abstract: A plurality of pixel formation portions in an image display portion are grouped so that K pixel formation portions form each pixel group, where K is an integer of two or more. The K pixel formation portions forming each of the pixel groups are connected to the same source bus line. Each of the pixel formation portions is provided with a connection control transistor configured to control an electrical connection state between the corresponding source bus line and a pixel electrode. The K connection control transistors included in the K pixel formation portions forming each of the pixel groups become an On state in periods different from one another. A source driver applies a video signal to each of the source bus lines in a time division manner in each horizontal scanning period.

  • Patent number: 10770018
    Abstract: The present application discloses a scanning signal line drive circuit capable of reducing power consumption and narrowing a picture-frame while ensuring high-speed scanning for image display. First and second gate drivers 410, 420 are arranged to face each other via a display unit 500. Based on a DC buffer method, odd-numbered gate lines are driven by the first gate driver 410 while even-numbered gate bus lines are driven by the second gate driver 420, and when each gate bus line GLi is to be brought into a non-selected state, charges are released from both ends thereof. For this purpose, for example, the end portion of the odd-numbered gate bus line on the first gate driver side is connected to a buffer made up of the activation and inactivation transistors M10, M13L, and the end portion of the odd-numbered gate bus line on the second gate driver side is connected to the inactivation auxiliary transistor M13R.

    Abstract: An account identification apparatus sets browsing authority for each of accounts such that browsing permission/prohibition is different for each of Web pages. Furthermore, the account identification apparatus causes a user terminal having accessed a predetermined Web site to transmit a request to each of the Web pages so as to acquire information about browsing permission/prohibition for each of the Web pages with regard to the user terminal and uses the acquired information about browsing permission/prohibition to identify an account with which the user terminal has logged in.

  • Publication number: 20200135136
    Abstract: When supply of power has stopped, voltages of GDM signals are set as follows. A clear signal that contributes to removal of charge at floating nodes (an output control node and a stabilization node) in each unit circuit included in a shift register is set to a voltage of ground, and other signals (a gate start pulse signal, gate clock signals, and a reference voltage) are set to a gate-on voltage. To implement such settings, a single power supply system configuration that uses a voltage of only one channel as a scanning line selection voltage is adopted.
