Patent number: 10684502Abstract: Disclosed are a display panel and manufacturing method thereof and a display device. The display panel includes a first substrate, a second substrate, a chip on film, and a shading array layer. The end of the first substrate extending beyond the second substrate forms a bonding end and the chip on film is bonded onto inner side of the bonding end. The inner surface of the first substrate is provided with metal signal wires located in non-pixel area. The shading array layer is located in the non-pixel area and completely shades the wires. Because the first substrate faces the viewer and the chip on film is bonded onto the inner side of bonding end, a bezel-less design is attained. The patterned shading layer forms a pattern corresponding to the metal signal wires to shade the wires for weakening lights reaching the wires and reducing reflectiveness of wires.Type: GrantFiled: January 17, 2018Date of Patent: June 16, 2020Assignee: HUIZHOU CHINA STAR OPTOELECTRONICS TECHNOLOGY CO., LTD.Inventors: Chengwen Que, Yong Fan

Patent number: 10490574Abstract: The present disclosure provides a low-reflection composite electrode including a first metal layer, a first transparent material layer and a second metal layer and a TFT array substrate using the same. The first metal layer, the first transparent material layer and the second metal layer are sequentially stacked. The low-reflection composite electrode has an extremely low reflection rate. In addition, the average reflection rate of the low-reflection composite electrode is lower than 3%, and even lower than 1% within the green light band. If the TFT array substrate is used in AM-OLED and AM-LCD, the gate and/or the source/drain of the TFT array substrate are the low-reflection composite electrodes, so the polarizer in the AM-LED and the low-reflection coating in the AM-LCD become unnecessary. Thus, the production cost can be reduced and the products can have its superiority.Type: GrantFiled: May 17, 2018Date of Patent: November 26, 2019Assignee: HUIZHOU CHINA STAR OPTOELECTRONICS TECHNOLOGY CO., LTD.Inventors: Yong Fan, Yuchun Hsiao, Chengwen Que
