Shift register and driving method thereof, gate driving circuit, array substrate, and display device
Patent number: 11037502Abstract: The present disclosure discloses a shift register and a driving method thereof, a gate driving circuit, an array substrate, and a display device. With a signal control circuit, a branch control circuit, a cascade signal output circuit and at least two scanning signal output circuits, each shift register can output at least two different scanning signals to correspond to different gate lines in an array substrate. This can reduce the number of shift registers in a gate drive circuit and the space occupied by the gate drive circuit and can achieve an ultra-narrow bezel design, as compared with an existing shift register that can only output one scan signal. Furthermore, as signals of different output control node do not influence each other, the stability of waveforms of the output scanning signals may also be improved, and a difference in the waveforms of the scanning signals is avoided.Type: GrantFiled: July 29, 2019Date of Patent: June 15, 2021Assignees: Hefei BOE Joint Technology Co., Ltd., BOE Technology Group Co., Ltd.Inventors: Zhidong Yuan, Yongqian Li, Can Yuan, Enming Xie -

Patent number: 10356327Abstract: A display control apparatus includes a touch detection unit that detects a touch operation on a touch panel, a unit setting unit that sets a unit of unit-by-unit image switching, and a switching unit that switches images so that if the unit is a first unit, an image the first unit ahead is displayed based on a predetermined touch-move of moving a touch position for a first distance, and if the unit is a second unit greater than the first unit, an image the second unit ahead is displayed based on the predetermined touch-move for a second distance longer than the first distance. The second distance is shorter than a distance of the predetermined touch-move required to display an image the second unit ahead of a first image when the unit set by the unit setting unit is the first unit.Type: GrantFiled: February 7, 2018Date of Patent: July 16, 2019Assignee: CANON KABUSHIKI KAISHAInventor: Toshiaki Ueguri

Patent number: 10338722Abstract: A tactile touch sensor (TTS) system and method allowing physical augmentation of a high-resolution touch sensor array (TSA) is disclosed. Physical augmentation is accomplished using a TSA physical overlay (TPO) placed on top of the TSA. The TPO is constructed to transmit forces to the underlying TSA. Force transmission is accomplished by either using a flexible overlay or with a rigid mechanical overlay that transmits user forces exerted on the overlay to the underlying TSA. Incorporation of TPO identifiers (TPI) within the TPO permits identification of the TPO by a TPO detector (TPD) allowing operational characteristics of the TSA to be automatically reconfigured to conform to the currently applied TPO structure by a user computing device (UCD). The UCD may be configured to automatically load an appropriate application software driver (ASD) in response to a TPI read by the TPD from the currently applied TPO.Type: GrantFiled: January 19, 2018Date of Patent: July 2, 2019Assignee: SENSEL, INC.Inventors: Ilya Daniel Rosenberg, John Aaron Zarraga

Patent number: 10013942Abstract: The disclosure provides a GOA circuit, a driving method thereof and a liquid crystal display device. The GOA circuit comprises a plurality of GOA units connected in cascade, wherein the N-stage GOA unit comprises a N-stage stage circuit, a N-stage Q point control circuit, a N-stage P point circuit, a N-stage output circuit and a switch circuit. The switch circuit is connected to the N-stage scan line for sending a turn-on signal to the N-stage scan line before the liquid crystal display device displays an image such that the thin-film transistor in the pixel connected to the N-stage scan line turns on. The disclosure may turn on the gate of each pixel when the display device is waken from the black screen to prevent the electricity leakage when the display device is wakened from the black screen, and may also increase the stability of the circuit.Type: GrantFiled: October 21, 2015Date of Patent: July 3, 2018Assignees: Shenzhen China Star Optoelectronics Technology Co., Ltd, Wuhan China Star Optoelectronics Technology Co., LtdInventors: Juncheng Xiao, Ronglei Dai, Shangcao Cao, Yao Yan
