Publication number: 20210132733Abstract: The present disclosure relates to touch display device and display panel. Provided are a touch display device and a display panel able to improve touch sensing performance by reducing crosstalk occurring between data lines and touch lines. A shield pattern is disposed in an area in which the touch lines overlap the data lines. A shield signal is applied to the shield pattern through shield lines in an area in which the shield pattern does not overlap the touch lines or the data lines. Direct capacitance is not formed between the touch lines and the data lines.Type: ApplicationFiled: September 11, 2020Publication date: May 6, 2021Inventors: Haewon LEE, JuHan KIM, Jinseong KIM

Patent number: 10871845Abstract: Disclosed are a touch display panel and a touch display device. In a touch display panel and a touch display device, a shielding pattern is arranged between a data link line and a touch link line in a non-active area of the touch display panel, and a signal corresponding to the touch driving signal is applied to the shielding pattern. Parasitic capacitance between the data link line and the touch link line is prevented in order to reduce noise on the touch sensing signal caused by voltage fluctuation on the data link line. Accordingly, it is possible to reduce the influence of display driving on touch sensing, thereby improving touch sensing during display driving.Type: GrantFiled: December 20, 2019Date of Patent: December 22, 2020Assignee: LG Display Co., Ltd.Inventors: YongChan Park, Jinseong Kim, Haewon Lee, JuHan Kim

Patent number: 10860128Abstract: A touch display panel and device. A common electrode is provided between a display driving signal line and a touch line. The common electrode functions as a shielding pattern that prevents display noise of a touch sensing signal without increasing the number of masks used to form the touch display device. A touch load reducing layer is disposed in a region between the touch line and the common electrode, except for a region in which the common electrode and pixel electrodes overlap. This reduces the load of the touch line and improves touch sensing performance without having an adverse effect on display driving.Type: GrantFiled: June 21, 2019Date of Patent: December 8, 2020Assignee: LG Display Co., Ltd.Inventors: SeungMok Shin, CheolSe Kim, JuHan Kim, HoonBae Kim, HyunHo Park, Jinseong Kim, YongChan Park
