Patent number: 11011553Abstract: The present invention teaches a TFT array substrate and a display device. The TFT array substrate disposes second fanout lines of the fanout area on a first metallic layer, and disposes first fanout lines of the fanout area on a second metallic layer. Data lines and their corresponding second fanout lines, and second fanout lines and their corresponding first fanout lines, are connected together through vias. The first metallic layer has a greater surface resistivity than that of the second metallic layer. The present invention's fanout lines corresponding to a same data line have a significantly increased total impedance, and the impedance variation of the fanout lines has a less impact. As data signals propagate to the data lines through the fanout lines, the data signals' arrival times to the data lines have little difference, thereby enhancing the display quality, more reliable manufacturing process, and lower risk for short circuit.Type: GrantFiled: September 18, 2018Date of Patent: May 18, 2021Assignee: WUHAN CHINA STAR OPTOELECTRONICS TECHNOLOGY CO., LTD.Inventor: Zhufeng Cui

Patent number: 10983400Abstract: At a corner of a TFT substrate where sealants are coated overlapping each other, a phenomenon that the sealants protrude into the display region is prevented by a structure that: the TFT substrate having an organic passivation film is formed as far as the outside of the display region. A groove-like organic passivation film removed portion is formed surrounding the display region. Since the sealants are coated overlapping each other at the corner, when a TFT substrate and a counter substrate are superposed at a predetermined gap, the width of the groove-like organic passivation film removed potion is made larger at the corner than the side in order to prevent the sealant from extending. Since an excessive sealant is absorbed in the groove-like organic passivation film removing portion of a larger width at the corner, the sealant can be prevented from protruding to the inside of the display region.Type: GrantFiled: June 9, 2020Date of Patent: April 20, 2021Assignee: Japan Display Inc.Inventor: Daisuke Ikeda
