  • Patent number: 8072439
    Abstract: The invention provides an interactive display that is controlled by user gestures identified on a touch detecting display surface. In the preferred embodiment of the invention, imagery is projected onto a horizontal projection surface from a projector located above the projection surface. The locations where a user contacts the projection surface are detected using a set of infrared emitters and receivers arrayed around the perimeter of the projection surface. For each contact location, a computer software application stores a history of contact position information and, from the position history, determines a velocity for each contact location. Based upon the position history and the velocity information, gestures are identified. The identified gestures are associated with display commands that are executed to update the displayed imagery accordingly. Thus, the invention enables users to control the display through direct physical interaction with the imagery.

  • Patent number: 8063866
    Abstract: A capacitor charged beforehand is discharged according to a light surrounding a display unit. A data is decreased similarly to the voltage between the electrodes of the capacitor. A trigger signal is outputted if the data becomes equal to or less than a threshold value. A clock signal whose cycle of changing levels gradually becomes long is generated. A count value is updated at each change of the clock signal's level and the updated count value is outputted. The count value is sampled when the trigger signal is outputted.

  • Patent number: 8040333
    Abstract: This invention discloses a type of radial circuit for use in driving LCD monitors. The radial circuit includes an odd-even column data generator. The odd-even column data generator receives data from a modulation counter and divides the data into two groups of data having opposite levels: odd column modulation data and even column modulation data. The odd-even column data generator then sends the two sets of data to a comparator comparing the display data and modulation data of the LCD. The comparator is used to control the odd and even columns of the LCD. This utility model divides all the columns in the same row into odd and even columns. An opposite driver voltage waveform is output from between the odd and even columns of the neighboring columns. While the odd columns discharge, the even column recharges. This type of simultaneous discharge and recharge process creates just the right mutual electric charge compensation; and it results in minimizing the electric charge dissipation which saves energy.

  • Patent number: 8035592
    Abstract: An apparatus for driving a display device includes a timing controller and a data driver. The timing controller encodes first gray scale data of a present frame, decodes encoded second gray scale data of a previous frame, compares the first gray scale data with the second gray scale data, and generates compensated gray scale data based on a result of comparing the first gray scale data with the second gray scale data. The data driver generates data signal based on the compensated gray scale data to provide the data lines with the data signal. The gray scale data are encoded so that the toggle number between adjacent data pins into which the gray scale data are output may be reduce. The encoded gray scale data are stored in a memory. Thus, the power consumption is reduced, and the EMI may be reduced.

  • Patent number: 8013820
    Abstract: A method, device and computer program are detailed for modulating write light. For a plurality of pixel locations of an electro-optic layer of an optical write valve and across each of a plurality of consecutive frames, a set of pixel data bits is modulated across a first and a second pulse width period of the frame. The first and second pulse width periods, and adjacent pulse periods of sequential frames, are separated from one another by a pulse-off period that is at least equal to a response time of the electro-optic layer during which no bits are modulated. Separately in each frame, write light is output from each of the plurality of pixel locations according to the modulated pixel data bits in the frame. In an embodiment, the set of pixel data bits are modulated by applying a voltage at a pixel location of the electro-optic layer in synchronism with illuminating a light source that illuminates that pixel location.
