  • Publication number: 20100097328
    Abstract: A method of determining touches from a data set output from a touch screen comprising an array of sensing nodes. The method comprises analyzing the dataset and identifies a node with a maximum signal value among all unassigned nodes, and, if present, assigns that node to a touch. A logical test is applied to each node that is a neighbor to the assigned node to determine if that node should also be assigned to the touch and the logical test is repeatedly applied to the unassigned neighbors of each newly assigned node until there are no more newly assigned nodes, or no more unassigned nodes, thereby assigning a group of nodes to the touch defining its area. This process can be repeated until all of the nodes of a touch panel are assigned to a touch. The method is ideally suited to implementation on a microcontroller.

  • Publication number: 20100097329
    Abstract: In a touch sensor comprising a plurality of sensing nodes, the touch location in each dimension is obtained from the node at which the sum of the signal values assigned to the touch on either side of said node are equal or approximately equal. Each of the sensing nodes is replaced by a plurality of notional sensing nodes distributed around its respective sensing node over a distance corresponding to an internode spacing. Signal values 2, 6, 11, 5 and 2 have been obtained for the distribution of signal across the touch sensor. These signals are notionally split in equal spacings in the range covered by each node, each notional signal being shown with vertical tally sticks. The touch coordinate is then determined by finding the position of the median tally stick. Since there are 26 notional signals, each with a signal value of 1, the position of the median signal is between the 13th and 14th notional signals, as indicated by the thick arrow.

  • Publication number: 20100097342
    Abstract: A method of tracking multiple touches over time on a touch sensor, for example a capacitive touch screen. The method analyses first and second touch data sets from adjacent first and second time frames. First, the touch data sets are analyzed to determine the closest touch in the second time frame to each of the touches in the first time frame, and calculating the separation between each such pair of touches. Then, starting with the pair of touches having the smallest separation, each pair is validated until a pairing is attempted between touches for which the touch in the second time frame has already been paired. At this point, the as-yet unpaired touches from the first and second touch data sets are re-processed by re-applying the computations but only including the as-yet unpaired touches. This re-processing is iterated until no further pairings need to be made. The method avoids complex algebra and floating point operations, and has little memory requirement.

    Abstract: A computer has a hardware layer module, a driver layer module, and an application layer module. The hardware layer module has a number of interface ports, and a preset interface port of the interface ports is coupled with the external display device. When the external display device is coupled to the hardware layer module via the preset interface port, the driver layer module outputs a notify message to the application layer module and controls the hardware layer module to read hardware information of the external display device. In addition, upon receiving the notify message, the application layer module can read the hardware information from the hardware layer module via the driver layer module and control the driver layer module to provide multiple displaying modes to the hardware layer module according to the hardware information. Thus, the external display device is enabled to display a video in a suitable displaying mode.

    Abstract: In one embodiment of the present invention, each pixel includes first and second subpixels. CS bus lines connected to the respective storage capacitors of the first and second subpixels are electrically independent of each other. A CS voltage has a waveform that inverts its polarity at least once a frame, which includes a first subframe for sequentially scanning a series of odd rows and a second SF for sequentially scanning even rows that have been skipped during the first SF. A source signal voltage varies so as to have two frames or subframes with mutually opposite polarities. A CS voltage has a waveform that has quite opposite consequences on the effective voltage of a subpixel of a pixel connected to the jth scan line to be selected during the first subframe and on that of another subpixel of a pixel connected to the (j+1)th scan line to be selected during the second subframe.

    Abstract: In one embodiment of the present invention, a liquid crystal display device is disclosed in which a gate driver applies a gate-on pulse so that a second period is longer than a first period. The first period and the second period are defined as follows. Among gate-on pulses applied before the moment of polarity inversion of a data signal, the last end of the gate-on pulse nearest to the moment of the polarity inversion is earlier than the end time of the horizontal period during which the gate-on pulse is applied. The first period starts at the last end of the gate-on pulse and ends at the end time of the horizontal period during which the gate-on pulse is applied. The second period starts at the moment of the polarity inversion and ends at the moment of the application start of the gate-on pulse nearest to the moment of the polarity inversion among the gate-on pulses applied after the polarity inversion.
