摘要： By a low power consumption driving method for an image display apparatus, unusual display may be prevented even if gate driving is not enough. When a rising edge of an output enable pulse is detected, a logic LOW gate driving signal is discharged to GND. When a falling edge of the output enable pulse is detected, the gate driving signal at GND is charged to logic HIGH. When a rising edge of the next output enable pulse is detected, the gate driving signal at logic HIGH is discharged to GND. When a falling edge of the next output enable pulse is detected, the gate driving signal at GND is charged to logic LOW. The image display apparatus is driven by the generated gate driving signals.

摘要： A parallax barrier includes a first electrode comprising a first sub-electrode and a second sub-electrode. A second electrode is opposed to the first electrode. A plurality of liquid crystal molecules are disposed between the first electrode and the second electrode. A parallax barrier driver provides a voltage difference between the first electrode and the second electrode to form a light-shielding region overlapping with both the first sub-electrode and the second sub-electrode, and forms a transverse electric field between the first sub-electrode and the second sub-electrode. It is noteworthy that the transverse electric field adjusts the rotation angles of the liquid crystal molecules to adjust the width of the light-shielding region, and the parallax barrier's transmittance can thereby be changed.

摘要： A dot inversion driving apparatus for an analog thin film transistor liquid crystal display (TFT LCD) panel and the method thereof are disclosed. The driving apparatus includes a control circuit and a source driver IC. The control circuit rearranges the orders and polarities of the grayscale signals of the TFT LCD panel, divides the grayscale signals into two groups, and outputs one of the groups during one of two half periods of each frame. The source driver IC collects the grayscale signals output by the control circuit. During the first half period using one scan line of the first group as a unit, the source driver IC outputs the grayscale signals to the pixels of the first group; and during the second half period using one scan line of the second group as a unit, the source driver IC outputs the grayscale signals to the pixels of the second group.

摘要： A driving method for a display system including a display panel and a backlight module is provided. A first directional surface light source and a second directional surface light source are respectively provided by a first light source and a second light source of the backlight module through a light guide plate. Images displayed by the display panel are thus transmitted to a left eye and a right eye. A data enable signal and an image signal are received to determine whether the image signal transmits a two dimensional image or a stereoscopic image according to the data enable signal. When the image signal is the two dimensional image, the first light source and the second light source are turned on simultaneously. When the image signal is the stereoscopic image, the first light source and the second light source are turned on at corresponding display periods, respectively.

摘要： A method for improving image stitch-in phenomenon is disclosed. The method includes the following steps. First, at least a first gray-scale line is inserted into the position of a corresponding number of scan line(s) in a frame. Then, at least a second gray-scale line is inserted into the position of a corresponding number of scan line(s) in the next frame. By inserting gray-scale line(s) into different positions sequentially, the image stitch-in phenomenon will not appear when changing a picture that has been displayed for a long time. The present invention can also improve the stitch-in phenomenon happening in an electronic photo frame and a liquid crystal display as well. Thus, the present invention is able to match the demand of human vision and improves the quality of visual display.
