摘要： A touch-sensitive screen and a resistance touch-sensitive device using the same, wherein said screen comprises: an insulating substrate, a rectangular conducting layer formed on said insulating substrate, a conducting layer electrode array formed on the four edges of said conducting layer, a conductive coat formed on said conducting layer, and a conductive coat electrode wherein, at least 3 pairs of the conducting layer electrodes are deployed in said conducting layer electrode array; each pair of the conducting layer electrodes are deployed on the parallel edges of the conducting layer symmetrically; and the conducting layer electrode is set on each edge of the conducting layer. As the conducting layer electrodes are deployed symmetrically on the parallel edges of the conducting layer, the electric filed lines tends to be evenly distributed when the voltage is loaded onto the edges of the conducting layer; thus the linearity of the equipotential lines is enhanced.

摘要： This invention describes methods and circuits for the segment driver circuit in a LCD driver system as well as application specific SEG decoder. The methods include the following steps: the array signal undergoes an inversion process (from 1 to 0, or from 0 to 1); the data and the array signal that has been processed through the inversion process then undergo a matrix operation; the signal that has gone through the matrix operation is then sent to a BBM (break before make) circuit. The signal processor of the application specific SEG decoder performs the inverse operation (from 1 to 0, or from 0 to 1) on the array signal; the decoding circuit performs the matrix operation on the signal that has been inversed (from 1 to 0, or from 0 to 1) before sending it to the BBM circuit. The methods described in this invention first process the array signal through field processing and inverse processing (from 1 to 0, or from 0 to 1) before undergoing the matrix operation, rather than first performing the matrix operation and then selecting an output based on the field signal. Therefore, this invention enhances the SEG decoder by simplifying the circuitry, reducing energy consumption, lowering cost, and making it easier to realize.

摘要： A touch-sensitive device includes a first conductive layer and a second conductive layer. The first conductive layer has at least a first edge and a second edge. The second edge is substantially parallel to the first edge and there is a voltage drop across the first conductive layer between the first edge and the second edge when a power supply is coupled to the first edge and the second edge. The second conductive layer is separated from the first conductive layer by a spacer layer. The second conductive layer includes multiple electrically isolated conductive regions. When a plurality of the conductive regions are in contact with the first conductive layer simultaneously, each of the plurality of the conductive regions generates an output signal and the magnitude of the output signal depends at least in part upon the conductive region's position relative to the first and second edges.
