    Abstract: A (liquid crystal display) LCD includes a pixel array and a gate driving circuit. The pixel array includes a plurality of first oxide thin film transistors, a first oxide thin film transistor of the first oxide thin film transistors with a shortest channel length having a first channel length. The gate driving circuit is coupled to the pixel array for driving the pixel array, and includes a plurality of second oxide thin film transistors. The second oxide thin film of the second oxide thin film transistors with a longest channel length has a second channel length. A ratio of the second channel length and the first channel length is greater than 1.5. By limiting the ratio of the second channel length and the first channel length, the aperture ratio of the display panel can be improved without deteriorating the operation stability of the LCD.

  • Patent number: 7592987
    Abstract: 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.
