Title: Liquid crystal display
Inventor: HIRAI YASUKATSU
IPC: G02F1/133
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a low power consuming liquid crystal display despite of a simple means by driving respective pixels across a plurality of first frame intervals by the same polar voltage and driving them by inverting the polarity in a plurality of second frame intervals. SOLUTION: The inversion is set to 3600 vertical period (3600 frame period) and a plurality of frame intervals of one polar of 3600 period and the following plurality of inversion frame intervals of 3600 period are repeated. A signal driver part 20 receives a Vref 1 and a Vref 2 from an inversion voltage correction part and outputs a voltage subtracting the residual voltage right after the inversion and a voltage based on the charge/discharge characteristics after that. The drive voltage is raised as every time of passing the respective frame intervals in a plurality of the normal-turn first frame intervals. Successively when it transfers to a plurality of second frame intervals inverted by a polarity inversion signal, the drive voltage of the frame interval in the initial inversion becomes small and gradually becomes larger to reach the maximum in the last frame interval.

Abstract: PURPOSE:To obtain a circuit inflicting less effect on the hysteresis characteristic due to dispersion of manufacture by connecting two resistors in series between a P-channel CMOS and an N-channel CMOS and connecting an NMOS and a PMOS in parallel with the resistor respectively. CONSTITUTION:The 1st resistor 12 and the 2nd resistor 14 are connected in series between the PMOS 11 and the NMOS 15. A common input signal is fed to the PMOS 11 and the NMOS 15. The NMOS 13 and the PMOS 16 are conencted in parallel with the resistors 12, 14 respectively. A potential at the connecting point between the resistors 12, 14 is inverted by an inverter 20 to form an output. The output voltage is fed in common to the NMOS 13 and the PMOS 16 via an inverter 23. Then the characteristic at the potential rising at an input terminal 17 depends on the ratio of the gm of the NMOS 13, 15 and the characteristic at the trailing potential depends on the ratio of the gm of the PMOS 11, 16. Since the hysteresis characteristic depends on the relation of the transistors of the same conduction type, the circuit is not susceptible to the effect of dispersion in the manufacture.
