Patent number: 11942040Abstract: 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.Type: GrantFiled: December 13, 2019Date of Patent: March 26, 2024Assignee: SHARP KABUSHIKI KAISHAInventors: Makoto Yokoyama, Nobuyuki Taya, Junichi Yamada

Patent number: 6084716Abstract: A single light emitted from a laser source is split into multiple beams. The multiple beams are illuminated by a multi-beam scanner to scan a substrate of interest. An optical system is provided for focusing the multiple beams independently on the substrate and directing a reflected light or a transmitted light of the multiple beams on the substrate. Aperture regulating members are disposed at equal intervals corresponding to the interval between the multiple beams for controlling the multiple beams directed from the substrate by the optical system. The multiple beams passed through their respective aperture regulating members are received by an optical detector assembly which detect a change in the amount of the multiple beams. The substrate is continuously moved by a movable table on a plane substantially vertical to the multiple beams and in a direction arranged at substantially a right angle to the scanning direction of the multiple beams.Type: GrantFiled: July 9, 1998Date of Patent: July 4, 2000Assignees: Kabushiki Kaisha Toshiba, Topcon CorporationInventors: Yasushi Sanada, Toru Tojo, Mitsuo Tabata, Kyoji Yamashita, Hideo Nagai, Noboru Kobayashi, Hisakazu Yoshino, Makoto Taya, Akemi Miwa
