Abstract: A source driver output circuit of a thin film transistor (TFT) liquid crystal display (LCD) includes first through n-th voltage generators, first through n-th switching portions, first through n-th sub switching portions, and a voltage-generating portion. The voltage generators receive first through n-th corresponding input voltages and generate first through n-th sub input voltages. The switching portions generate the sub input voltages as first through n-th corresponding output voltages when activated, or cut off the sub input voltages when deactivated. The sub switching portions connect predetermined share lines to the output voltages when activated, or cut off the predetermined share lines when deactivated. The voltage-generating portion receives predetermined first and second voltages and applies predetermined precharge voltages to the share lines. Therefore, the slew rate of a signal input to the panel from the source driver can be improved, and current consumption in the source driver can be reduced.

Abstract: A touch system includes a touch surface and at least two cameras associated with the touch surface. The at least two cameras acquire images of the touch surface from different locations and having overlapping fields of view. A digital signal processor is associated with each camera. The digital signal processors process pixel data acquired by selected pixel subsets of the at least two digital cameras to generate pointer characteristic data when a pointer exists in the acquired images. The pointer characteristic data identifies edges of the pointer. A master digital signal processor triangulates the edge information in the pointer characteristic data to determine a bounding area that represents a pointer perimeter.

Abstract: A dual voltage switch enables the generation of a pulse which toggles between user-provided first and second voltages (V1 and V2), for which the positive and/or negative slew rates are programmable by means of a user-provided capacitance. A first switch conducts a current I1 between V1 and a common output node in response to a first control voltage, and a second switch conducts a current I2 between V2 and the common output node in response to a second control voltage. A capacitance C is connected to the common output node. A control circuit alternately provides the first and second control voltages such that the common output node is pulled up to V1 at a transfer rate of I1/C when the first control voltage is provided, and pulled down to V2 at a transfer rate of ?I2/C when the second control voltage is provided.

Abstract: A liquid crystal display apparatus which is adapted to divide one frame period into a preset writing period, a first writing period, a first holding period, a second writing period, and a second holding period, to be driven in this sequence. The first and second writing periods have reverse writing voltage polarities and the second writing period is set to be about ½ of the first writing period.

Abstract: A potential of a data signal line S during a scanning period is charged to a substantially intermediate potential of a data signal at a corresponding frame. Thus, extremely large dispersion does not occur in a potential of each pixel capacitor with respect to a potential of the data signal line S, so that it is possible to restrict dispersion of a leak current flowing via an active element of each pixel. Thus, potential variation of a pixel PIX is reduced, so that it is possible to improve display quality during a non-scanning period. That is, in an active-matrix-type liquid crystal display, when a frame frequency is reduced by setting the non-scanning period to be sufficiently larger than a scanning period while a standby image is being displayed so as to realize low power consumption, the display quality is improved.

Abstract: An apparatus and method are disclosed for displaying an image having high frequency components. The image is displayed on a display device that includes a plurality of display elements arranged in both horizontal and vertical directions. The display elements represent colors, such as red, green and blue. A pixel data generator generates for each display element first pixel data corresponding to the luminance levels of red, green and blue colors in the image. A smoothing filter eliminates false colors in the image by applying weighting coefficients to the first pixel data to modify the luminance levels of the first pixel data, thereby producing second pixel data having second color element data corresponding to luminance levels of the respective colors. Each display element of the display is driven in accordance with the second color element data.

Abstract: Radiation from a collimated linear source (7, 8) is directed partly into a light guide structure (6) and partly glancing over the surface of the light guide structure (6). The radiation (15, 20) travelling inside the light guide is coupled out by micro-optical structures to illuminate the underlying reflective or superlying transmissive LCD. Radiation (17A, 17B) travelling across the surface outside the light guide (6) is directed towards an array of light sensitive detectors. Interruption of this radiation by a pen (21) or a finger (21) is detected and the position of the interruption is deduced.

Abstract: In a liquid crystal device, spherical-shaped semiconductor devices are mounted in a dispersive fashion on a wiring pattern extending toward a liquid crystal sealing region from input terminals connected to a flexible board. Each spherical-shaped semiconductor device is produced by forming a semiconductor device element on the surface of a spherical-shaped semiconductor material. In production of an electro-optical panel, MIS transistors are first produced in the form of spherical-shaped semiconductor devices, and then one spherical-shaped semiconductor device is installed in each pixel on an active matrix substrate, thereby allowing the MIS transistors to be produced at an optimum temperature without restriction caused by heat resistance of the substrate. When the active matrix substrate is adhesively bonded to an opposite substrate, the spherical-shaped semiconductor devices serve as spacers which allow the substrates to be precisely spaced a desired distance apart from each other.
