LIQUID CRYSTAL DISPLAY DEVICE, ESPECIALLY DIVIDING TWO-DIVIDED FREQUENCY BY TWO

摘要

PURPOSE: A liquid crystal display device is provided to overcome the electromagnetic interference(EMI) problem generated due to the high driving frequency by allowing the liquid crystal panel to be operated by four divided frequency. CONSTITUTION: A liquid crystal display device includes a liquid crystal panel(100), a plurality of odd number data driving integrated circuits(DIC#1,DIC#3...) and a plurality of even number data driving integrated circuits(DIC#2,DIC#4...). The liquid crystal panel is provided with a plurality of data lines. The plurality of odd number data driving integrated circuits receives the data corresponding to the odd number output among each of the channels through the first odd number data line and receives the data corresponding to the even number output among each of the channels through the first even number data signal line. The plurality of odd number data driving integrated circuits simultaneously drives the input data corresponding to the odd number data lines and the even number data lines. The plurality of even number data driving integrated circuits receives the data corresponding to odd number output among each of the channels through the second odd data signal lines and receives the data corresponding to the even number among each of the channels through the second even number data signal lines. And, the plurality of even number data driving integrated circuits simultaneously drives the odd number data line and the even number of data lines corresponding to the input data with synchronizing to the second horizontal start signal.
