Patent number: 10263019Abstract: A flexible panel includes a substrate, a first insulating layer, a second insulating layer, a sacrificial layer, and a metal wiring layer. The substrate has an active area, a peripheral area, and an intermediate area. The first insulating layer is in the three areas of the substrate, and the first insulating layer in the intermediate area has a first pattern. The second insulating layer is on the first insulating layer. The second insulating layer in the intermediate area has a first opening extending along a first direction, so that the second insulating layer does not cover the first pattern of the first insulating layer. The sacrificial layer is between the first insulating layer and the second insulating layer in the intermediate area, and does not cover the first pattern of the first insulating layer. The metal wiring layer extends between the active area and the peripheral area.Type: GrantFiled: April 19, 2018Date of Patent: April 16, 2019Assignee: AU OPTRONICS CORPORATIONInventors: Pei-Yun Wang, Cheng-Wei Jiang, Ting-Yu Hsu, Ya-Qin Huang, Hsiang-Yun Hsiao, Chia-Kai Chen

Patent number: 9891501Abstract: A method of fabricating a polycrystalline silicon thin film transistor device includes the following steps. A substrate is provided, and a buffer layer having dopants is formed on the substrate. An amorphous silicon layer is formed on the buffer layer having the dopants. A thermal process is performed to convert the amorphous silicon layer into a polycrystalline silicon layer by means of polycrystalization, and to simultaneously out-diffuse a portion of the dopants in the buffer layer into the polycrystalline silicon layer for adjusting a threshold voltage. The polycrystalline silicon layer is patterned to form an active layer. A gate insulating layer is formed on the active layer. A gate electrode is formed on the gate insulating layer. A source doped region and a drain doped region are formed in the active layer.Type: GrantFiled: September 14, 2016Date of Patent: February 13, 2018Assignee: AU OPTRONICS CORPORATIONInventors: Hsiang-Yun Hsiao, Chia-Kai Chen, Shih-Liang Lin, Ting-Yu Hsu, Pei-Yun Wang, Ya-Qin Huang, Cheng-Wei Jiang
