Publication number: 20210132438Abstract: The invention provides a display apparatus including a reflective display and a front light source module. The front light source module is provided with a light emitting element configured to emit an illuminating beam. There is an included angle ? between an optical axis of the light emitting element and a normal line of a display surface of the reflective display, and 0°?|?|?75°. The illuminating beam passes through space between the front light source module and the reflective display and is reflected by the reflective display to be converted into a display beam. The invention provides a display apparatus with low energy consumption, and even though an electronic device using the display apparatus has been used for a relatively long time, it is not necessary to frequently replace a battery or recharge the display apparatus.Type: ApplicationFiled: August 27, 2020Publication date: May 6, 2021Applicants: HannStar Display(Nanjing) Corp., HannStar Display CorporationInventor: Yen-Chung Chen

Patent number: 10001855Abstract: A touch display device and a method for driving the same are provided. The touch display device includes a display panel and a touch panel. In the method, the touch display device provides a source output signal and outputs a plurality of pixel voltages during an enable period of the source output signal to drive the display panel. The touch display device periodically reduces the enable period of the source output signal according to a horizontal synchronization signal corresponding to a turned-on sequence of each row of pixels, so as to establish a touch sensing period. Based thereon, the touch sensing circuit scans the touch panel during the touch sensing period that does not overlap with the enable period of the source output signal, so as to obtain sensing signals for accurately indicating electrical variations of the touch panel.Type: GrantFiled: December 11, 2015Date of Patent: June 19, 2018Assignees: HannStar Display(Nanjing) Corp., HannStar Display CorporationInventor: Chien-Wu Chen

Patent number: 9933649Abstract: A display panel including a first substrate, a plurality of pixel units disposed on the first substrate and a shielding layer is provided. Each pixel unit includes a thin-film transistor, a first signal line and a second signal line electrically connected to the thin-film transistor. The shielding layer includes a first portion located on a peripheral region and a second portion located on a non-rectangular display region. An inner contour of an orthogonal projection of the first portion of the shielding layer on the first substrate includes a plurality of first line segments and a plurality of second line segments. The first line segments are parallel to orthogonal projections of the first signal lines on the first substrate. The second line segments are respectively parallel to orthogonal projections of the second signal lines on the first substrate.Type: GrantFiled: November 22, 2016Date of Patent: April 3, 2018Assignees: HannStar Display(Nanjing) Corp., HannStar Display CorporationInventors: Hsuan-Chen Liu, Chien-Ting Chan

Patent number: 9046945Abstract: Disclosed is a touch control device, comprising a substrate, a plurality of sensing units, an insulating layer, an electric bridge, a protection layer, a supporting part, an element layer and a glue part. A plurality of sensing units are disposed on the substrate in an interval between two of sensing units to expose portions of the substrate. The insulating layer covers the exposed substrate. The electric bridge covers the insulating layer, and two ends of the electric bridge are respectively connected to two sensing units among the plurality of sensing units. The protection layer covers the electric bridge and the sensing unit. The supporting part covers the protection layer. The element layer is disposed on the supporting part. As a result, an accommodating space is formed therebetween. The accommodating space is filled up with the glue part to glue the protection layer and the element layer.Type: GrantFiled: February 27, 2013Date of Patent: June 2, 2015Assignee: HannStar Display (Nanjing) Corp.Inventors: Hao-Chieh Huang, Ting-Chen Chiu

Patent number: 8859086Abstract: The present invention provides a bonded structure of a flexible circuit board of a touch screen for preventing overflow including a touch sensor panel having a flexible circuit board adhered thereon. The flexible circuit board and/or the touch sensor panel have a glue dam disposed thereon, and a length of the glue dam is larger than a width of the flexible circuit board. The bonded structure of the flexible circuit board of the touch screen for preventing overflow in the present invention disposes the glue dam at a position at the bonding area of the flexible circuit board bonded to the touch sensor panel to effectively reduce the overflow to a side of the flexible circuit board outside the touch sensor panel, and an appearance of the overflow and voids during bonding could be avoided.Type: GrantFiled: May 24, 2012Date of Patent: October 14, 2014Assignee: HannStar Display(Nanjing) Corp.Inventors: Xin Yi, Jianshe Bi
