Patent number: 9293081Abstract: A method of operating a light emitting, image display device that is configured to normally display to one or more viewers, a corresponding image thereof with a relatively wide viewing angle and relatively good contrast, includes selectively outputting to one or more peripheral portions of the wide viewing angle, privacy-protecting light rays of sufficient luminance to substantially reduce, for corresponding viewers viewing from the respective one or more peripheral portions of the relatively wide viewing angle, the otherwise normal and relatively good contrast of the image so as to thereby inhibit viewing of the image from the respective one or more peripheral portions. In one embodiment, the method is carried out using an organic light emitting diode (OLED) panel and a light source part disposed on a backside of the OLED panel and comprising at least one light guide plate and at least one light source.Type: GrantFiled: October 24, 2013Date of Patent: March 22, 2016Assignee: Samsung Display Co., Ltd.Inventors: Young-Nam Yun, Kyu-Seok Kim

Patent number: 9292107Abstract: A mobile telephone includes an active-pixel sensor in conjunction with a DSP chipset and a light source allowing the telephone to detect horizontal movement across a flat surface. When moved horizontally, the telephone detects relative position movement and transmits a new position to a nearby computer. The computer interprets this new position as a cursor control position and moves its cursor. The telephone is placed into a mode such that physical buttons or displayed buttons on a touch screen operate as a mouse click when pressed. The mouse click is interpreted by the telephone and transmitted to the computer to affect the mouse click. The telephone is also placed into a mode such that raising it from the flat surface indicates that a subsequent three-dimensional movement is interpreted as a mouse click. A shake, rotation or sharp movement is interpreted as a mouse click which is transmitted to the computer to implement the mouse click in conjunction with its cursor.Type: GrantFiled: October 29, 2012Date of Patent: March 22, 2016Assignee: Trend Micro Inc.Inventors: Rong Bo, Mingqi Zhong, Haibo Zhang

Patent number: 9274628Abstract: Aspects of the invention provide virtual hover zones. When a user lowers a hovering stylus while remaining within a hover zone, cursor control is modified to be more easily controllable by the user. If the user pauses the stylus in mid-air before lowering the stylus, and if the stylus remains within the hover zone, then upon touchdown the cursor may be moved to the projection of the location where the stylus was paused. Any action that may be taken in response to the touch down may be sent to the projection location as well. Also provided are cursor control zones. A dampening zone may be used to provide dampened cursor movement feedback in response to movement input provided by a pointing device. Also, a dead zone may be used to prohibit cursor movement in response to movement input provided by the pointing device.Type: GrantFiled: August 2, 2013Date of Patent: March 1, 2016Assignee: MICROSOFT CORPORATIONInventors: Alexander J.

Patent number: 9244568Abstract: A two-dimensional touch sensor comprising a plurality of electrodes arranged in a mesh pattern on a substrate. Each electrode is formed by interconnected metal traces, the metal being intrinsically opaque, but the metal traces being sufficiently narrow to be practically invisible. The metal traces have a width less than or equal to 10 ?m and occupy less than or equal to 5% of the area of each electrode. The electrodes can be deposited additively via a printing process, for example using copper as the metal. The narrow width of the tracks allows the film to be highly transparent, since the electric field used in capacitive touch screens can be made to propagate with very low metal densities.Type: GrantFiled: April 10, 2009Date of Patent: January 26, 2016Assignee: Atmel CorporationInventor: Harald Philipp

Patent number: 9229252Abstract: A stereographic display apparatus and a vehicle headlight can include an optical modulator including a position sensor and a voltage supply. The position sensor can be configured to detect an inclined angle, and the voltage supply can be configured to apply a voltage to the optical modulator in accordance with the inclined angle output from the position sensor.

Patent number: 9208717Abstract: Brightness irregularities that develop in a light emitting device due to is persion among pixels in the threshold values of TFTs used for supplying electric current to light emitting devices become obstacles to improved image quality of the light emitting device. As an image signal input to a pixel from a source signal line, a desired electric potential is applied to a gate electrode of a TFT for supplying electric current to an EL device, through a TFT having its gate and drain connected to each other. A voltage equal to the TFT threshold value is produced between the source and the drain of the TFT 105. An electric potential in which the image signal is offset by the amount of the threshold value is therefore applied to the gate electrode of the TFT. Further, TFTs are disposed in close proximity to each other within the pixel, so that dispersions in the TFT characteristics do not easily develop.Type: GrantFiled: January 15, 2014Date of Patent: December 8, 2015Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Hajime Kimura, Yoshifumi Tanada

Patent number: 9164606Abstract: The disclosed embodiments relate to a system that provides power for a touch-enabled display, wherein the touch-enabled display cycles between a display mode and a touch mode. During the display mode, the system drives a display-mode voltage to the touch-enabled display through a power output, wherein the power output is coupled through a display-mode capacitor CD to ground. Next, during a transition from the display mode to the touch mode, the system couples the power output through a touch-mode capacitor CT to ground, wherein CT was previously charged to a touch-mode voltage, which causes the power output to rapidly transition to the touch-mode voltage. Then, during the touch mode, the system drives the touch-mode voltage through the power output.Type: GrantFiled: July 31, 2012Date of Patent: October 20, 2015Assignee: Apple Inc.Inventors: Christoph H.
