Method of forming a color filter touch sensing substrate

ActiveUS20100136868A1Decrease in equivalent resistanceIncrease touch sensitivityPhotomechanical apparatusSemiconductor/solid-state device manufacturingAuxiliary electrodeTouch panel
A method of forming a color filter touch sensing substrate integrates touch-sensing structures / elements of a touch panel into the inner side of the color filter substrate, which faces a thin film transistor substrate, and forms patterned assistant electrodes on the surfaces of the transparent sensing pads for decreasing the equivalent resistance of the touch-sensing structures / elements. Moreover, since an adjacent transparent conductive layer and an assistant electrode layer are patterned to form the transparent sensing pads and the patterned assistant electrodes, a simplified pattern-transferring process can be applied to the transparent sensing pads and the patterned assistant electrodes, or bridge structures can be formed from the assistant electrode layer for electrically connecting between some transparent sensing pads. Therefore, the forming process is simplified.

InactiveUS20080231617A1Improve reliabilityShift of threshold voltage can be suppressedTransistorSolid-state devicesDriver circuitShift register
To provide a display device in which reliability of a driver circuit can be improved by suppressing shift of the threshold voltage of a TFT. The minimum power supply voltage that is optimal for driving a transistor used in the driver circuit is found by actually changing voltage applied to a gate of the transistor. Specifically, voltage that is output from an output circuit included in the driver circuit when a value of power supply voltage applied to a shift register is changed is monitored. Then, a value of the power supply voltage is found such that a value of the voltage output from the output circuit satisfies a value enough to operate a pixel portion, and the driver circuit is operated using the power supply voltage.
