Abstract: A bistable liquid crystal display (LCD) including a display panel, a plurality of column data drivers, and a plurality of row data drivers is provided. Each column data diver receives a plurality of phase control signals, a first high driving voltage, a first low driving voltage, and a display data, selects one of the phase control signals according to the display data, and alternately outputs the first high driving voltage and the first low driving voltage according to the selected phase control signal to form a column driving signal for the display panel. Each row data diver receives one of the phase control signals, a second high driving voltage, and a second low driving voltage and alternately outputs the second high driving voltage and the second low driving voltage according to the received phase control signal to form a row driving signal for the display panel.

Abstract: A 12-bit DAC includes a resistor string, three 16-to-1 selectors and an adder. The 12-bit DAC receives a 12-bit digital input data and provides a corresponding analog output voltage with 3-segmented conversion. The resistor string includes a plurality of voltage-dividing units for providing a plurality of reference voltages corresponding to each segment of conversion. After receiving the plurality of reference voltages generated by the resistor string, the three 16-to-1 selectors output 3 reference voltages corresponding to the three segments of conversion according to the 4 most significant bits, 4 least significant bits and the other 4 bits in the 12-bit digital input data, respectively. The adder can then generate the corresponding output analog voltage by summing the 3 reference voltages.
