  • Publication number: 20210048699
    Abstract: Provided is a display device including a display panel which allows a curvature portion thereof to be narrowed near a terminal portion even when circuit blocks are arranged in the curvature portion. For a data line in the form of a polyline consisting of a plurality of short straight line segments in a first curvature portion 12a of a display panel 10, as the distance from a terminal portion 16 increases, the slant angle of each straight line segment increases, the number of data lines d decreases, and hence the width of a data line area decreases. Accordingly, the number of unit circuit blocks 70 in a parallel circuit block 80 disposed in a circuit area can be increased by widening the circuit area in proportion to the decrease in the width of the data line area.

  • Patent number: 10861392
    Abstract: Provided are a display device drive method and a display device, both of which allow a pixel circuit to be discharged without leaving any electric charge in an OFF sequence for powering off the display device. During an OFF sequence period, a first node N1 is set to a first ground potential Vgnd1, which is a potential higher than an initialization potential Vini. As a result, even when a second ground potential Vgnd2 is supplied through a data line Dj to a second conductive terminal of a drive transistor T1, a gate terminal of the drive transistor T1 is not charged with a gate-to-source voltage Vgs. Therefore, an organic EL display device 1 is powered off with the gate terminal of the drive transistor T1 being charged with the first ground potential Vgnd1 leaving no electric charge in a pixel circuit 11 after the power off.

  • Publication number: 20200135110
    Abstract: The present application discloses an organic EL display device adopting the SSD method, which enables sufficient charging with a data voltage and sufficient internal compensation in a pixel circuit even in a case that a display image has a higher resolution. There are provided m demultiplexers corresponding to m sets of data signal line groups, each of which is a set including k data signal lines (in this case, k=2). Each demultiplexer simultaneously turns selection control signals at a low level (active) during a reset period before a scanning signal line is selected. In this case, a white voltage is supplied as a reset voltage from a data-side drive circuit to each data signal line via each demultiplexer. After that, during the select period for the scanning signal line, each demultiplexer sequentially switches, with the selection control signals, a data signal line to which the data signal is to be supplied from the data-side drive circuit among corresponding k data signal lines.
