Patent number: 8542217Abstract: An apparatus is controlled to detect a location of an object on a touch surface of a panel. An input scanner arrangement introduces at least two beams of radiation into the panel for propagation by internal reflection, and sweeps the beams inside the panel across a sensing area. An output scanner arrangement is synchronized with the input scanner arrangement so as to receive the beams from the input scanner arrangement while they are swept across the sensing area and to direct the beams onto at least one radiation detector. Thereby, each beam is introduced and received on opposite ends of the sensing area. A data processor is connected to the radiation detector and operated to identify the location based on an attenuation of the beams caused by the object touching the touch surface within the sensing area.Type: GrantFiled: June 22, 2009Date of Patent: September 24, 2013Assignee: FlatFrog Laboratories ABInventors: Ola Wassvik, Kennet Vilhelmsson

Patent number: 8514151Abstract: A pixel is provided in which normal display of an image is possible even if a sustain period is shorter than an address period in a driving method combining digital gray scales and time gray scales, and in which operation can be compensated by changing the electric potential of a signal line even for a case in which the EL driver transistor becomes normally on due to deterioration. One of a source region and a drain region of an erasure TFT is connected to an electric current supply line, and the remaining one of the source region and the drain region is connected to a gate signal line. It is possible to change the voltage between a gate and a source of an EL driver TFT by changing the electric potential of the gate signal line so that the EL driver TFT is placed in a non-conducting state with certainty with this structure, even for cases in which the EL driver TFT becomes normally on due to a shift in the value of its threshold voltage.Type: GrantFiled: July 6, 2009Date of Patent: August 20, 2013Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventor: Hajime Kimura

Patent number: 8502750Abstract: The picture quality on a plasma display panel shall be improved when the contrast and/or the brightness are reduced. This is achieved by estimating the reduction of the dynamic occurring in the front-end of the data processing of the plasma display device and by compensating it in the back-end. Specifically, the gain and/or offset of the video input data are adjusted and the power level of the adjusted video data is measured. The resulting power level information is updated on the basis of an attenuation information. The updated power level is used for the power management and the level of the video data being reduced in the front-end is increased on the basis of the attenuation information. Thus, the dynamic of the video and, as a result, the picture quality are improved.Type: GrantFiled: February 16, 2008Date of Patent: August 6, 2013Assignee: Thomson LicensingInventors: Cédric Thebault, Carlos Correa, Sébastien Weitbruch

Patent number: 8497823Abstract: Display irregularities in light emitting devices, which develop due to dispersions per pixel in the threshold value of TFTs for supplying electric current to light emitting elements, are obstacles to increasing the image quality of the light emitting devices. An electric potential in which the threshold voltage of a TFT (105) is either added to or subtracted from the electric potential of a reset signal line (110) is stored in capacitor means (108). A voltage, in which the corresponding threshold voltage is added to an image signal, is applied to a gate electrode of a TFT (106). TFTs within a pixel are disposed adjacently, and dispersion in the characteristics of the TFTs does not easily develop. The threshold value of the TFT (105) is thus cancelled, even if the threshold values of the TFTs (106) differ per pixel, and a predetermined drain current can be supplied to an EL element (109).Type: GrantFiled: November 2, 2010Date of Patent: July 30, 2013Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Hajime Kimura, Yoshifumi Tanada
