摘要： A display control device has: a shift register generating n shift pulses in series; a data hold block configured to hold n gradation data; and a DA converter for converting the n gradation data into corresponding gradation voltages. The data hold block includes: n first latch circuits configured to respectively latch the n gradation data in series in synchronization with the n shift pulses; and n second latch circuits provided between the DA converter and the n first latch circuits. An electrical connection between the first latch circuits and the second latch circuits is cut off while the first latch circuits receive the n gradation data. After the first latch circuits finish latching all the gradation data, the n gradation data are simultaneously supplied to the DA converter from the first latch circuits through the second latch circuits.

摘要： A display panel driver has a single resistor string for gamma correction and a signal power supply, which have heretofore been required for each of red, green, and blue, and is small in size and has its power consumption reduced. Voltage generator including a single resistor string having n reference voltage terminals generates n reference voltages. Voltage selector selects and outputs m red gradation voltages Vr(0) through Vr(15), m green gradation voltages Vg(0) through Vg(15), and m blue gradation voltages Vb(0) through Vb(15) from the n reference voltages. The display panel driver provides all of a gamma correction curve for red, gamma correction curve for green, and a gamma correction curve for blue with a single resistor string and a pair of power supplies including a ground potential.
