Patent number: 9202403Abstract: A pixel circuit is provided. The pixel circuit is electrically coupled to a data line, a first scan line, and a second scan line. The pixel circuit includes a first pixel unit, a second pixel unit, and a third pixel unit. The first pixel unit is electrically coupled to the data line and the second scan line, to determine a first displayed gray scale of the first pixel unit. The second pixel unit is electrically coupled to the data line and the first scan line, to determine a second displayed gray scale of the second pixel unit. The third pixel unit is electrically coupled to the data line, the first scan line, and the second scan line, to determine a third displayed gray scale of the third pixel unit.Type: GrantFiled: September 13, 2012Date of Patent: December 1, 2015Assignee: Au Optronics CorporationInventors: Meng-Ju Tsai, Yu-Sheng Huang, Chia-Lun Chiang, Yan-Ciao Chen

Patent number: 9030504Abstract: A driving method of a display panel is described. A display panel including a pixel array is provided. The pixel array includes N scan lines, M data lines, and a plurality of first pixel units and a plurality of second pixel units electrically connected to the scan lines and the data lines. When an image is displayed with a wide-viewing angle mode, a first scanning procedure is performed to sequentially scan the first scan line of the scan lines to the Nth scan line of the scan lines in order. When the image is displayed with a narrow-viewing angle mode, the second scanning procedure is performed to sequentially scan the Nth scan line of the scan lines to the first scan line of the scan lines in order.Type: GrantFiled: January 18, 2012Date of Patent: May 12, 2015Assignee: Au Optronics CorporationInventors: Yan-Ciao Chen, Yu-Sheng Huang, Chia-Lun Chiang, Meng-Ju Tsai

Patent number: 9024944Abstract: Pixel structural designs on a display panel are disclosed. Each pixel on the display panel includes a plurality of sub-pixels. The sub-pixels are arranged sequentially along a vertical direction and used for displaying different colors in a circle. The display panel in the disclosure can be switched between a two-dimensional mode and a three-dimensional mode. In the three-dimensional mode, parts of the sub-pixels are disabled for forming a shielding area. Other adjacent sub-pixels form a pixel displaying unit.Type: GrantFiled: December 3, 2012Date of Patent: May 5, 2015Assignee: AU Optronics CorporationInventors: Yan-Ciao Chen, Yu-Sheng Huang, Chia-Lun Chiang, Meng-Ju Tsai

Patent number: 8928568Abstract: A pixel includes sub-pixels each of which includes a first display region, a second display region, a third display region, a first capacitor, and a second capacitor. The first capacitor connects the second display region with the third display region. The second capacitor connects the first display region to the third display region via a switch. When the switch is activated, the potential of the third display region is decreased via the second capacitor, the potential of the first display region is increased via the second capacitor, and the potential of the second display region is decreased via the first capacitor. A display panel and driving method in a display panel are also disclosed herein.Type: GrantFiled: April 13, 2012Date of Patent: January 6, 2015Assignee: AU Optronics CorporationInventors: Chia-Lun Chiang, Yu-Sheng Huang, Yan-Ciao Chen, Meng-Ju Tsai
