摘要： In a passive liquid crystal display, frames or fields are displayed for different time periods to achieve gray scale. The voltage pulses applied to the column electrodes have substantially constant values during row scanning periods or field scanning periods to reduce power consumption. The lines of the display may be divided into odd and even fields in an interlaced configuration to suppress flicker and to further reduce power consumption by reducing frame rate.

摘要： Two separate power supplies are employed to generate electrical potentials for driving row and column electrodes of LCDs. One or more energy storage devices are preferably used together with the two power supplies for generating such potentials. In the first phase, the energy storage devices are charged and in the second phase, such devices and the power supplies are employed to generate the appropriate potentials for driving the row and column electrodes. Such schemes permit the column electrodes to be driven through a voltage range much smaller than the convention IAPT driving schemes and vastly reduces the power consumption by the driver. The total voltage dynamic range experienced by the driver circuit is comparable to the IAPT driving scheme.

摘要： A low DC power rail-to-rail buffer amplifier is suitable for liquid crystal display application. The buffer amplifier comprises: a dc bias stage, a pair of complementary differential amplifiers, a second stage amplifier, and output stage. The dc bias stage is used for the dc bias of the differential amplifiers and the second stage to obtain a rail-to-rail operation. This buffer amplifier can be operated in the power supply ranges of 5.5 V to the breakdown voltage. Simulated results show that the circuit draws only 5.3 μA static current.
