Abstract:
A display method for driving a color-sequential display of an electronic device is provided. When the electronic device is not at low power mode, a first image is displayed first by using a second color data and a first color data of the first image sequentially to drive the display. Next, a second image is displayed by using a second color data and a third color data of the second image sequentially to drive the display. When the electronic device is at low power mode, the respective luminance of the first and the second images are obtained. Then, the respective luminance of the first image and the second image are sequentially used to drive the display.

Abstract:
A driver integrated circuit (IC) for driving a panel having pixels controlled by gate lines and data lines is disclosed, including a power circuit for generating a high level voltage and a low level voltage, a timing controller, a source driving circuit controlled by the timing controller to drive the data lines, a gate driving circuit controlled by the timing controller to selectively enable one of the gate lines for a line period. The gate driving circuit first asserts the selected gate line with the high level voltage in order to activate the corresponding pixels for receiving the driving signals from the corresponding data lines, and the gate driving circuit subsequently asserts the selected gate line with the low level voltage such that the corresponding pixels are still activated for receiving the driving signals. An LCD device utilizing the driver IC is also provided.

Abstract:
A liquid crystal display module and its scanning circuit board therein. There are a first scanning circuit and a second scanning circuit located at both ends of each of the scanning lines in the LCD panel. While scanning, both the first scanning circuit and the second scanning circuit drive the same scanning line simultaneously, so as to equivalently reduce the delay effect caused by the RC time constant. The first scan driving circuit and the second scan driving circuit could be placed on different scanning circuit boards with the same layout. The scanning circuit board has two connectors at the both ends and a scanning interface at a side. The scanning circuit board could be used at both sides of the LCD panel by the rotation of 180°.
Abstract:
A method of reducing flickering and inhomogeneous brightness in an LCD. The method serially connects each scan line connecting a plurality of pixels in a row with a resistor to form a scan line circuit. The resistor is connected between the first pixel of the scan line and the voltage input terminal of the scan line, so that the gate voltage entering the TFT in the first pixel deforms. The voltage of the TFT decreases when it is turned off, minimizing screen flickering and inhomogeneous brightness due to the capacitor charge coupling effect between the first pixel and the last pixel on a scan line.
Abstract:
A method of forming a TFT-LCD with self-aligned transparent conducting layer over a substrate comprises the following steps. Initially, a first metal layer is formed on the substrate. Then, an insulating layer is formed on the substrate. A silicon layer is formed above the insulator layer. A doped silicon layer is formed above the silicon layer. A second metal layer is formed on the doped silicon layer, the silicon layer, and the substrate to define S/D structures and data lines. Then, a passivation layer is formed on the second metal layer, the silicon layer, and the insulating layer. A transparent conducting layer is formed on the passivation layer. Then, a negative photoresist is formed on the transparent conducting layer. A front-side exposure step is performed by using a first photomask. Additionally, a back-side exposure step is performed by using the first metal layer and the second metal layer as a mask. After removing the unexposed negative photoresist, an etching step is performed to define the transparent conducting layer.
Abstract:
An additional high quality insulating layer is grown over the substrate after the formation of the gate electrode of a thin film transistor (TFT). The growth temperature of the insulating layer can be higher than conventional method and the insulating layer is more free of pin-holes. After the insulating layer in the thin oxide region of the TFT is etched away, conventional fabrication processes are followed. The dielectric of the thin film oxide region is the same as that of the conventional TFT; but the dielectric in the vicinity of the thin oxide region, the crossovers of the data lines and the scan lines, and the gate dielectric layer of the TFT are now composed of the high quality insulating layer. The TFT structure can improve the yield of fabrication by confining the channel region in the shadow of the gate electrode to reduce the leakage photo-current, and by reducing the steps at cross-overs steps and interconnections to avoid open-circuit.
