    摘要: An active TFT circuit structure with current scaling function is disclosed, which includes a current source, a data line, a scan line, a direct current voltage source, capacitors and four transistors, wherein the capacitors form a cascade structure. During the ON-state, the two of the transistors are turn-on based on the voltage provided by the scan line, so that the data current provided by the current source flows through the data line-and the transistor which is one of the opened transistors, thereby arriving an emitting light element and the transistor connected to the emitting light element. When the pixel circuit changes from ON- to OFF-state, the voltage of the node between the storage capacitors reduces due to the feed-through effect of one of storage capacitor, thereby reducing the driving current of the emitting light element. Therefore, it can be achieved the current scaling function.

    摘要: A touch panel device having high touch sensitivity includes sensing capacitors, switches, storage capacitors, a differential amplifier and a signal processing unit. During a sense period, the switches are periodically turned on alternately for periodically transferring the charges of the sensing capacitors to the storage capacitors. The differential amplifier is put in use for amplifying the voltage difference of two corresponding storage capacitors for generating a touch readout signal. The signal processing unit performs an OR operation on two touch readout signals generated during different sense periods based on different sensing capacitor combinations regarding same panel touch position for providing a touch position signal.
