Patent number: 10783830Abstract: A pixel circuit has enhanced performance by minimizing noise effects from the data and reference voltage lines. To prevent data line noise from interfering with the drive transistor gate voltage during emission, a triple gate isolation is used between the data voltage line and the gate of the drive transistor by which three transistors are connected between the data voltage line and the gate of the drive transistor. To further improve the isolation, one of the middle nodes of the triple gate farthest from the data voltage line is connected to one floating node that is connectable to a reference voltage during the threshold compensation phase. A first capacitor is used for the threshold compensation, and a second capacitor is used to scale the data voltage during programming. The threshold compensation and data programming operations are thereby independent of each other to minimize programming time.Type: GrantFiled: May 14, 2019Date of Patent: September 22, 2020Assignee: Sharp Kabushiki KaishaInventors: Tong Lu, Michael James Brownlow
