Publication number: 20240099086Abstract: A display may have an array of pixels. Display driver circuitry may supply data and control signals to the pixels. Each pixel may have seven transistors, a capacitor, and a light-emitting diode such as an organic light-emitting diode. The seven transistors may receive control signals using horizontal control lines. Each pixel may have first and second emission enable transistors that are coupled in series with a drive transistor and the light-emitting diode of that pixel. The first and second emission enable transistors may be coupled to a common control line or may be separately controlled so that on-bias stress can be effectively applied to the drive transistor. The display driver circuitry may have gate driver circuits that provide different gate line signals to different rows of pixels within the display. Different rows may also have different gate driver strengths and different supplemental gate line loading structures.Type: ApplicationFiled: November 17, 2023Publication date: March 21, 2024Inventors: Cheng-Ho Yu, Chin-Wei Lin, Shyuan Yang, Ting-Kuo Chang, Tsung-Ting Tsai, Warren S.

Patent number: 10955969Abstract: A light-guide assembly and an access control system are provided. The light-guide assembly is used as an interface for touch input. The light-guide assembly includes a light-guide element and a light source disposed on a lateral surface of the light-guide element. The light source emits a first light with a first wavelength. The light-guide element has an upper surface, a lower surface, and an inner layer that is made of a light-transmissive material. The first light enters the light-guide element through the lateral surface and propagates inside the light-guide element for reacting to the touch event occurring on the upper surface. A verification data used in an access control system is formed when the touch event is sensed and identified. A light-activation element of the assembly activates the first light propagating inside the light-guide element and produces a second light that is used to provide a visual effect.Type: GrantFiled: August 20, 2019Date of Patent: March 23, 2021Assignee: PIXART IMAGING INC.Inventors: Chao-Chien Huang, Hung-Ching Lai, Ting-Yang Chang, Yi-Hsien Ko
