摘要： A multiplex electrophoretic display driver circuit comprises a memory unit, a display controller and a voltage driving unit. The memory unit has two registers respectively storing the current and former gray-level matrix signals. The gray-level matrix signal contains gray-level data corresponding to electrophoretic pixels. The display controller has an encoding circuit and a counting circuit. The encoding circuit generates a difference-value matrix signal containing difference values according to a difference between the current and former gray-level matrix signals and then generates a voltage-difference matrix signal containing voltage-difference signals corresponding to the electrophoretic pixels. The counting circuit receives the difference-value matrix signal and counts to generate refreshing values corresponding to the difference values. The encoding circuit adds the refreshing values to a next-cycled difference-value matrix signal to generate a new voltage-difference matrix signal. The voltage driving unit drives the electrophoretic pixels according to the voltage-difference matrix signal.

摘要： A circuit for amplifying a display signal transmitted to a repair line by using a non-inverting amplifier is disclosed, which comprises a voltage follower, a non-inverting amplifier, a repair line, a thin film transistor (TFT) and a liquid crystal (LC) capacitor. The voltage follower is electrically connected to a data driver chip to thereby provide a display signal to the non-inverting amplifier. The non-inverting amplifier amplifies the display signal to thus obtain an amplified display signal, and transmits the amplified display signal to the TFT and the LC capacitor through the repair line. The amplified display signal is kept at a desired voltage level when the LC capacitor receives the amplified display signal.
