摘要： A start protection circuit of a gate driver, which is applied in a liquid crystal display, includes a detection circuit and a switch. The detection circuit monitors a gate low voltage to generate a control signal. The switch is electrically connected to the detection circuit and controlled by the control signal, for transmitting a gate high voltage. The detection circuit outputs the gate low voltage first and monitors if the gate low voltage has reached a predetermined level. When the gate low voltage has reached the predetermined level, the detection circuit turns on the switch to output the gate high voltage.

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： An apparatus and a method for eliminating an image sticking of a liquid crystal display (LCD) are provided. The image sticking occurs when the LCD is turned off. The LCD includes a data driver and a number of pixels coupled to a common voltage. The apparatus includes a voltage detector and a voltage switching device. The voltage detector detects a system voltage of the LCD and outputs a control signal according to the system voltage. The voltage switching device is coupled to the voltage detector for selectively providing a data voltage or the common voltage as a driving voltage of the data driver according to the control signal. The voltage switching device is controlled by the control signal to provide the common voltage to the data driver when the system voltage is less than a reference voltage.
