  • Patent number: 11942040
    Abstract: In a display device having a non-rectangular display unit, occurrence of a difference in luminance between a region with a high load and a region with a low load is suppressed. A region inside the display unit is segmented into a high-load region with a high load on horizontal scanning lines (an initialization control line and a write control line) and a low-load region with a low load on horizontal scanning lines. An initialization control line and a write control line that are disposed in the high-load region are driven by a discharge driver and a scan driver, respectively. An initialization control line and a write control line that are disposed in the low-load region both are driven by, for example, the discharge driver.

  • Patent number: 11762247
    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.
