Abstract: A circuit for predicting the dead time is provided. The circuit includes a plurality of integrators, a plurality of comparators, and a logic circuit. Based on a reference signal provided externally, a first charging operation is delayed by a predetermined delay time during one period of the reference signal, such that the integrators maintain at a voltage level in a next period of the reference signal. Then, the integrators further perform another charging operation during the next period, and the charging voltage is compared with the maintained voltage value. When the charging voltage exceeds the maintained voltage, a reset signal is generated by the logic circuit.

Abstract: The present invention relates to a data driving system and method for driving a panel. The data driving system comprises: a gamma voltage supply and a D/A converter. The gamma voltage supply produces a plurality of gamma voltages. The D/A converter receives the gamma voltages, a first pixel value and a second pixel value, and converts the first pixel value and the second pixel value to a corresponding gamma voltage in the gamma voltages. When the D/A converter converts the first pixel value, the gamma voltages have a first polarity offset. When the D/A converter converts the second pixel value, the gamma voltages have a second polarity offset. Because the data driving system of the invention periodically switches the first polarity offset and the second polarity offset of the gamma voltage supply, an offset in the driving voltage is eliminated by the first polarity (positive) offset and the second polarity (negative) offset in space and time. Therefore, there is no band mura in the panel.

Abstract: The invention relates to a reset device for a scan driver. The scan driver is used for driving a control circuit of a display. The reset device comprises: a first input terminal, a second input terminal and a reset circuit. The first input terminal receives a first input voltage. After the first input voltage inputs to the first input terminal, the second input terminal receives a second input voltage. The second input voltage has a temporary section and a stable section. At the stable section, the second input voltage is larger than the first input voltage. When the first input terminal receives the first input voltage, the reset circuit outputs a reset signal to the scan driver. When the second input voltage is larger than a threshold value at the temporary section, the reset circuit clears the reset signal. According to the reset device of the invention, the scan driver maintains at a reset state so as to prevent that outputs of the scan driver to be at high level at the same time of supplying power. Therefore, the reset device can lower the malfunction of the control circuit and decrease the probability of damage and breakdown to maintain normal operation and life of the control circuit can be maintained.

Abstract: A method for driving an LCD with class-A operational amplifiers. The LCD has a positive operational amplifier for driving pixels with positive voltages, a negative operational amplifier for driving pixels with negative voltages, and a detector. The method includes using the detector to determine which operational amplifier is to be used to drive a next pixel. If the next pixel need be displayed with a positive voltage, then the positive operational amplifier is used to drive the next pixel. If the next pixel need be displayed with a negative voltage, then the negative operational amplifier is used to drive the next pixel.

Abstract: The present invention relates to an illumination device of an LCD projection system. The illumination device comprises a light source, a quarter-wave retardation and a wire grid polarizer. The light source is used for providing light. The quarter-wave retardation is disposed near the light source. The wire grid polarizer is disposed parallel to the quarter-wave retardation, and is associated with the quarter-wave retardation to polarize the light from the light source. P-polarized light can pass through the wire grid polarizer. S-polarized light cannot pass through the wire grid polarizer, and is reflected to the quarter-wave retardation to become circular polarized light. The circular polarized light is reflected by a parabolic surface of the light source and passes through the quarter-wave retardation again to convert into p-polarized light. The converted p-polarized light can pass through the wire grid polarizer. Therefore, the illumination device of the invention can provide high-efficiency polarized light. The illumination device can achieve high polarization conversion efficiency, and can be manufactured easily to reduce costs.
