Patent number: 11887529Abstract: A pixel array is provided. The pixel array includes a plurality of pixels, wherein each of the pixels includes a light emitting diode, a first transistor, a second transistor, a third transistor, a fourth transistor, and a fifth transistor. The first transistor receives a first data signal and a first scan signal. The second transistor is coupled to the first transistor and an anode of the light emitting diode. The third transistor receives a system high voltage and a first control signal, and is coupled to the second transistor. The fourth transistor is coupled to an anode of a light emitting diode of an adjacent pixel, a control terminal of the third transistor, and a cathode of the light emitting diode. The fifth transistor is coupled to the cathode of the light emitting diode, and receives a second control signal and a system low voltage.Type: GrantFiled: April 19, 2022Date of Patent: January 30, 2024Assignee: Au Optronics CorporationInventors: Ya-Jung Wang, Jing-Wun Jhang, Rong-Fu Lin, Nien-Chen Li, Hsien-Chun Wang, Che-Chia Chang, June Woo Lee, Hsin-Ying Lin, Chia-Ting Hsieh, Chien-Fu Huang, Sung-Yu Su

Patent number: 11514852Abstract: A pixel array is provided. The pixel array includes a plurality of red pixels, a plurality of green pixels, and a plurality of blue pixels. Each green pixel includes a light emitting diode (LED), a first transistor, a second transistor, a third transistor, and a fourth transistor. The LED receives a system low voltage. The first transistor receives a first data signal and a first scan signal. The second transistor is coupled to a second end of the first transistor and the anode of the light emitting diode. The third transistor receives a system high voltage and a first control signal, and is coupled to a first end of the second transistor. The fourth transistor is coupled to the anode of the light-emitting diode of an adjacent green pixel, a control terminal of the third transistor, and the anode of the light-emitting diode.Type: GrantFiled: April 20, 2022Date of Patent: November 29, 2022Assignee: Au Optronics CorporationInventors: Ya-Jung Wang, Jing-Wun Jhang, Rong-Fu Lin, Nien-Chen Li, Hsien-Chun Wang, Che-Chia Chang, June Woo Lee, Hsin-Ying Lin, Chia-Ting Hsieh, Chien-Fu Huang, Sung-Yu Su

Patent number: 7553551Abstract: A pellicle frame for pellicle for use with a photomask in a wafer lithographic processing process is disclosed to have the frame body made of a material containing silver that absorbs sulfide released from other materials of the pellicle, preventing formation of crystals on the mask pattern of the photomask after exposure. In an alternate form, the pellicle frame is made of aluminum alloy, ceramics, or stainless steel, and then coated with a layer of silver and a black coating of polymer, for example, Teflon, PEEK (Polyaryletherketone) or PFA (Perfluoroalkoxy).Type: GrantFiled: August 16, 2005Date of Patent: June 30, 2009Inventors: Ming-Lung Chiu, Nien-Chen Li
