  • Signal line driving circuit for an LCD display
    Patent number: 6806859
    Abstract: A signal line drive circuit for an LCD display having a reduced chip size and circuit scale. The drive part for two neighboring channels has a pair of registers 10L and 10R, a pair of first data latch circuits 12L and 12R, a pair of first switching circuits 14L and 14R, a pair of second data latch circuits 16L and 16R, a pair of level shifters 18L and 18R, a pair of D/A converters 20L and 20R, a pair of output amplifiers 22L and 22R, a pair of second switching circuits 24L and 24R, and a pair of output pads 26L and 26R. All K positive gray-scale voltages V1-VK are supplied to the left-side D/A converter 20L from gray-scale voltage generating circuit 28. On the other hand, all K negative gray-scale voltages V′K-V′1 are supplied to the right-side D/A converter 20R from gray-scale voltage generating circuit 28.
