LIQUID CRYSTAL DISPLAY DEVICE AND INTEGRATED CIRCUIT HAVING DATA OUTPUT PARTS FOR PLURAL PORTS

摘要: PROBLEM TO BE SOLVED: To reduce electromagnetic wave noises from an I/O signal part and unnecessary waves exerting adverse influence upon other devices or circuits by arranging the changed positions of a data output on mutually deviated during one period internal clock signal. SOLUTION: The display input 2 is same as 1CLKI 1 1CLK iraternal 3 1CLKO 4 sum periods 1CLK, time interval equivalent to 2CLKI. edge each signals 3, 8 expresses active latch circuit connected immediately before in integrated after source driver IC. For instance, simultaneous are divided into three so that delayed front 0.5, 1.5
