Publication number: 20240023228Abstract: An LCD display module includes a polygon flexible printed circuit to produce a thinner display. The polygon flexible printed circuit connects a driver integrated circuit to a printed circuit board assembly and a glass substrate. The polygon flexible printed circuit has a narrow minor end connected to the glass substrate and a wider major end connected to the printed circuit board assembly. Because the polygon flexible printed circuit has different end widths, the polygon flexible printed circuit permits reduced spacing of electronic components in proximity of the narrower minor end. The LCD display module also includes a shielding can in physical communication with the printed circuit board assembly to reduce electromagnetic interference between the printed circuit board and the polygon flexible printed circuit.Type: ApplicationFiled: August 16, 2022Publication date: January 18, 2024Inventors: Tsung-Chin Cheng, Chin-Chung Wu, Hong-Ji Huang

Publication number: 20240019741Abstract: An LCD display module uses an ingenious gradient flexible printed circuit to produce a larger and thinner display. The gradient flexible printed circuit connects a driver integrated circuit between a printed circuit board assembly and an ITO circuit on a glass substrate. The gradient flexible printed circuit has a narrow, minor end connected to the ITO circuit and a wider, major end connected to the printed circuit board assembly. Because the gradient flexible printed circuit has different end widths, the gradient flexible printed circuit permits reduced spacing of electronic components in proximity of the narrower minor end. Signaling between the electronic components is improved, and electromagnetic shielding is reduced. The gradient flexible printed circuit also has a smaller dimensional stack, thus allowing for a larger display viewing area and a thinner display.Type: ApplicationFiled: July 18, 2022Publication date: January 18, 2024Inventors: Wu Chin-Chung, Tsung-Chin Cheng, Hong-Ji Huang

Patent number: 8451419Abstract: A touch panel and methods for manufacturing the same is provided. The method for manufacturing a touch panel includes providing a substrate and forming a photospacer layer on the substrate. Subsequently, a single lithography process is performed to the photospacer layer to define a main spacer and a sensor spacer. After forming a conductive layer on the main spacers and sensor spacers, a part of the conductive layer is removed to expose a top part and a part of a upper side of the main spacer. Accordingly, the conductive layer on the top part of the main spacer can be completely removed. In addition, the aperture ratio loss due to over-etching the conductive layer on the color filter can be prevented by the conductive layer remained on a lower side of the main spacer.Type: GrantFiled: December 3, 2009Date of Patent: May 28, 2013Assignee: AU Optronics Corp.Inventors: Tsung-Chin Cheng, Zeng-De Chen, Seok-Lyul Lee
