Patent number: 8111222Abstract: The output uniformity of a display device, such as a self light emitting display device, is improved by detecting the emitted brightness of pixels of the display device using an external detection system, controlling the pixel intensity to determine the non-uniformity of the driver circuits connected with the pixels, and generating a calibration factor for the pixels to modify the output of the driver circuits. Calibration can be performed for each pixel, or each group of pixels, such as each row and column of pixels.Type: GrantFiled: November 14, 2003Date of Patent: February 7, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: Mark T.

Patent number: 8085217Abstract: A system, method, and computer program product are provided for compensating for crosstalk during the display of stereo content. In use, display content is received for being outputted utilizing a display system. Such display system inherently exhibits crosstalk, whereby an amount of left eye display content is displayed to a right eye of a user and an amount of right eye display content is displayed to a left eye of the user. Thus, prior to outputting the display content utilizing the display system, the display content is processed utilizing a graphics processor to compensate for the amount of the left eye display content to be displayed to the right eye of the user and the amount of the right eye display content to be displayed to the left eye of the user. In one embodiment where the crosstalk is a function of pixel location, the compensation may also be a function of pixel location. [e.g. in the case of a liquid crystal display (LCD), etc.].Type: GrantFiled: August 8, 2006Date of Patent: December 27, 2011Assignee: NVIDIA CorporationInventors: Gerrit A. Slavenburg, Thomas F.

Patent number: 8081142Abstract: Provided is a circuit driving method which can minimize a problem generated by a peak current in a display memory device. Data to be transferred to a display panel is read out from a memory cell array storing binary information. The read-out data are stored in source data buffers and a plurality of source data buffers are divided into several groups and then enabled. An enable signal for each group is derived from a single enable signal and has a different delay time. In the source data buffers delayed by each group and enabled, consumption of current is distributed so that a peak current flowing in the overall source data buffer is lowered. Thus, reliability in the operation of a circuit is improved and the operation speed increases.Type: GrantFiled: September 4, 2003Date of Patent: December 20, 2011Assignee: Syncoam Co., Ltd.Inventor: Seong Ik Jeong

Patent number: 8077155Abstract: A notebook computer is upgraded by providing stylus-cooperating indicia near the keyboard and an optical stylus that can recognize the indicia. The indicia includes a sketch pad area that cooperates with the optical stylus to transmit movement data to the computer. The movement data is relative in position and absolute in orientation, providing .DELTA.X and .DELTA.Y in the sketch pad's coordinate plane rather than the stylus's. Other indicia represents tool buttons recognized by both humans and the stylus. A stylus and stickers kit is used to upgraded existing notebook computers. New ones can be manufactured with the stylus-cooperating indicia in place or the indicia may be provided on a substrate that may be attached to any notebook computer, as selected and positioned by the end user. The stickers or substrate is thin enough to permit the notebook computer to be closed as usual.Type: GrantFiled: August 16, 2007Date of Patent: December 13, 2011Inventor: Peter H. Rehm

Patent number: 7916099Abstract: An active matrix electroluminescent display has means for interrupting the drive of current through the display element. Row driver circuitry for the display has a shift register and logic arrangement (50, 54) for generating the drive voltage for the interrupting means, and which includes a pulse having a duration which can be varied up to substantially the full field period less the address period. The signal or signals propagated through the shift register arrangement (50) control the pulse duration. This arrangement provides reduced driver complexity to allow control for the row by row addressing of the pixels with control of the overall light emission period of each row. The control enables a scrolling addressing scheme to be implemented.Type: GrantFiled: October 5, 2004Date of Patent: March 29, 2011Assignee: Koninklijke Philips Electronics N.V.Inventors: William A.
