Patent number: 8624877Abstract: An optical touch display apparatus includes a light-transmitting display panel, a backlight module, a visible light source, an invisible light source, an image sensing apparatus and a processing circuit. The light-transmitting display panel has a first surface and a second surface opposite to each other. The first surface has a display area. The backlight module is disposed on the second surface. The image sensing apparatus is configured to sense an image above the display area. When a pointer is located in the display area and reflects invisible light which passes through the display area so that the image sensing apparatus senses the invisible light reflected by the pointer, the processing circuit calculates the position of the pointer related to the display area according to the image sensed by the image sensing apparatus. In addition, an optical operation apparatus is also provided.Type: GrantFiled: February 15, 2011Date of Patent: January 7, 2014Assignee: Pixart Imaging Inc.Inventors: Hung-Ching Lai, Wu-Chieh Liu, Hui-Hsuan Chen

Patent number: 8605073Abstract: A transistor whose channel region includes an oxide semiconductor is used as a pull down transistor. The band gap of the oxide semiconductor is 2.0 eV or more, preferably 2.5 eV or more, more preferably 3.0 eV or more. Thus, hot carrier degradation in the transistor can be suppressed. Accordingly, the circuit size of the semiconductor device including the pull down transistor can be made small. Further, a gate of a pull up transistor is made to be in a floating state by switching of on/off of the transistor whose channel region includes an oxide semiconductor. Note that when the oxide semiconductor is highly purified, the off-state current of the transistor can be 1 aA/?m (1×10?18 A/?m) or less. Therefore, the drive capability of the semiconductor device can be improved.Type: GrantFiled: February 14, 2011Date of Patent: December 10, 2013Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Atsushi Umezaki, Hajime Kimura

Patent number: 8599159Abstract: Touch panel operation devices, methods, and programs set a touch-off determination time, and determine that the touch-off has occurred if the state at which the touch panel detects the user not touching the touch panel has continued for the set touch-off determination time or more after the touch-off was detected. When the user is touching the touch panel, the devices, methods, and programs acquire a touch coordinate, select an object corresponding to the acquired touch coordinate, and scroll-display the selected object based on a displacement of the acquired touch coordinate. The devices, methods, and programs determine whether the touch coordinate was acquired and displaced just before the touch-off was detected, and if the touch coordinate was acquired and displaced just before the touch-off was detected, set the touch-off determination time to be longer than if the touch coordinate was acquired and not displaced just before the touch-off was detected.Type: GrantFiled: September 14, 2011Date of Patent: December 3, 2013Assignee: Aisin AW Co., Ltd.Inventors: Shigehiko Sugeda, Koichi Ushida, Kazuyoshi Yamamoto

Patent number: 8547371Abstract: Prior to increasing the voltage level of an input signal to be sampled in a step-by-step manner and writing a signal voltage Vsig at a desired voltage level, a precharge is performed which writes a precharge voltage Vpre, lower than the signal voltage Vsig, so as to apply the same voltage Vpre to the gate of a drive transistor in advance. This not only provides a reduced gate-to-source voltage of the drive transistor at the time of writing of the signal voltage Vsig but also extends a mobility correction time required for a mobility correction operation. The extension of the mobility correction time required for the mobility correction operation ensures a relatively smaller variation in the correction time, thus suppressing the variation in brightness. The extension also permits a write pulse to be set to the optimal pulse width.Type: GrantFiled: January 7, 2008Date of Patent: October 1, 2013Assignee: Sony CorporationInventors: Takao Tanikame, Yukihito Iida, Tetsuo Minami, Katsuhide Ucnino
