Abstract: A pixel circuitry of a display device and a display method thereof are provided herein. The pixel circuitry includes a scan switch, a storage element, and a sampling circuitry. The scan switch has a first terminal coupled to a data line and configured to be asserted according to a scan signal. The storage element is coupled to a second terminal of the scan switch and configured to store a pixel voltage from the data line. The sampling circuitry is configured to sample the stored pixel voltage of the storage element and to obtain a reference voltage for the display device according to the sampled signal. By sampling the stored pixel voltage of the storage element, whether the pixel voltages with different polarities are symmetry can be detected for avoiding flickers.

Abstract: The present invention is directed to a system and method of adaptively controlling a light-emitting diode (LED) backlight. A content analyzer analyzes luminance of image data to be displayed on a display panel. An LED current controller controls illumination of the LED backlight via an LED driver according to an analysis result of the content analyzer. The LED current controller over-drives the LED backlight such that a drive current flowing in the LED backlight is above a normal current, when the analysis result of the content analyzer indicates that the luminance of image data is above a predetermined value.

Abstract: An inverted staggered (bottom gate) thin film transistor (TFT) for active matrix liquid crystal display is processed with three masks. The first mask is used to pattern a metal film on a glass substrate as the gate of the TFT, the scan line of the TFT array, and a portion of the data line of the TFT array. The second mask is used to form a TFT mesa with a gate dielectric layer, an a-Si layer as channel, and a heavily-doped n+s-Si layer for contacting the source and the drain of the TFT. A third mask is used to pattern the transparent conductive indium-tin oxide film as the pixel electrode, the source/drain electrodes of the TFT, and the interconnections of the data line.
