  • Publication number: 20140054156
    Abstract: A touch-sensing electrode structure includes multiple first electrodes and multiple second electrodes. Each first electrode includes a longitudinal part extending in a first direction and multiple branch parts connected to the longitudinal part. The second electrodes are disposed on at least one side of each longitudinal part, and each of the second electrodes at least spreads over a region between two adjacent branch parts of each of the first electrodes.

  • Publication number: 20140028618
    Abstract: A touch apparatus including a touch panel, a sensing controller and a capacitance matching unit is provided. The touch panel has a plurality of scan ports and a plurality of sensing ports, wherein the touch panel outputs a plurality of sensing signals through the sensing ports. The sensing controller drives the touch panel through a plurality of scan lines correspondingly coupled to the scan ports, and receives the sensing signals through a plurality of sensing lines correspondingly coupled to the sensing ports. The capacitance matching unit is coupled between the touch panel and the sensing controller through the scan lines, and is used for tuning an equivalent capacitance of the touch panel.

  • Publication number: 20130249413
    Abstract: A pixel circuit includes a control switch module, a capacitor, a driving switch, and a light emitting element. The control switch module is enabled and disabled according to a scan signal. A first end of the capacitor can be electrically connected to the control switch module, and a second end of the capacitor can be electrically connected to a voltage level. The capacitor receives and stores a predetermined driving voltage when the control switch module is enabled. Area of the capacitor occupies more than 20% area of the pixel circuit. The driving switch can be electrically connected to the capacitor and a voltage source for controlling a driving current flowing through the driving switch according to the predetermined driving voltage stored in the capacitor. The light emitting element emits light according to the driving current flowing through the driving switch.
