DATA DRIVE CIRCUIT, LIGHT-EMITTING DISPLAY DEVICE USING THE SAME, AND DRIVE METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a data drive circuit for displaying uniform images.

SOLUTION: The data drive circuit includes a holding latch part 603, including a plurality of holding latches for storing data, a signal generation part 605 including a plurality of digital/analog converters for receiving data and for generating data signals, a first switching part 604 located between the holding latch part 603 and the signal generation part 605, and a second switching part 606 which is electrically connected to the signal generation part 605 and is for transmitting the data signals to data lines. The first switching part 604 electrically connects respective holding latches to respective digital/analog converters, during a current frame so as to be different from the immediately preceding frame.
