Patent number: 9215804Abstract: A circuit stack structure is provided. The circuit stack structure includes a conductor layer having metal wires arranged at intervals, propping portions respectively disposed in a gap between any two of the neighboring metal wires, and a protective layer covering the metal wires and the propping portions. The propping portions are electrically isolated with the metal wires. With supporting by the propping portions, all regions of a top surface of the protective layer corresponding to one of the propping portions are coplanar with all regions of the top surface of the protective layer corresponding to each of the metal wires.Type: GrantFiled: March 18, 2013Date of Patent: December 15, 2015Assignee: HANNSTAR DISPLAY CORPORATIONInventors: Yung-Fu Chen, Rong-Bing Wu, Po-Hsiao Chen, Chien-Hao Wu

Patent number: 8853066Abstract: A method for manufacturing pixel structure is provided. A patterned conductor layer including a gate, a scan line and a conductor pattern is formed on a substrate. A gate insulating layer, a metal oxide material layer and an etching stop material layer are formed on the substrate. Using the patterned conductor layer as mask, a patterned photoresist layer is formed on the etching stop material layer through a back exposure process. Using the patterned photoresist layer as mask, a metal oxide channel layer and an etching stop layer are formed above the gate. A source and a drain are formed on the etching stop layer. A passivation layer is formed on the substrate. A halftone mask is used to form a photosensitive layer on the passivation layer. The metal oxide material layer and the etching stop material layer on the scan line and the conductor pattern are removed.Type: GrantFiled: February 1, 2013Date of Patent: October 7, 2014Assignee: Hannstar Display CorporationInventors: Po-Hsiao Chen, Chien-Hao Wu, Rong-Bing Wu, Chang-Ming Chao

Patent number: 8625041Abstract: An array substrate, liquid crystal display for the same and manufacturing method thereof are described. The array substrate includes a substrate, a plurality of scan lines, a plurality of data lines, a plurality of contact pads, a passivation layer and transparent conducting layer. The substrate has a first display region, a second display region and a first non-display region. The contact pads are disposed in the first non-display region. The transparent conducting layer disposed in the passivation layer includes a first pixel electrode, a second pixel electrode and a plurality of comb electrode. The first pixel electrode and second pixel electrode are disposed in the first display region and the second display region wherein the widths of the first pixel electrodes either are equal to or approximate the widths of the second pixel electrodes. The comb electrodes are disposed in the first non-display region and connected to the contact pads.Type: GrantFiled: January 21, 2012Date of Patent: January 7, 2014Assignee: Hannstar Display CorporationInventors: Yung-Fu Chen, Rong-Bing Wu, Po-Hsiao Chen, Chien-Hao Wu

Publication number: 20130342799Abstract: A driven electrode structure of an in-plane switching liquid crystal display is divided into a plurality of sub-regions, each of the sub-regions includes a plurality of sub-driven electrodes, a plurality of intervals is formed between adjacent sub-driven electrodes, so as each of the sub-regions has the intervals, and at least two of the intervals in the sub-regions are different from one another. By changing the width or shape of each sub-driven electrode, at least two of the intervals in the sub-regions are different from one another, so as the Mura condition of the in-plane switching liquid crystal display can be obscure, so as the Mura defect can be minimized uniformly without being visually recognized by human eyes and further improve the visual defect of the Mura.Type: ApplicationFiled: March 19, 2013Publication date: December 26, 2013Applicant: HANNSTAR DISPLAY CORP.Inventors: CHENG-JUI HUANG, RONG-BING WU, CHIEN-HAO WU, PO-HSIAO CHEN
