PRINTED CIRCUIT BOARD AND LIQUID CRYSTAL DISPLAY DEVICE HAVING THE SAME

摘要

A printed circuit board and a liquid crystal display device with the same are provided to prevent distortion of an image displayed on a liquid crystal panel and an afterimage. A printed circuit board includes a substrate, a boosting circuit, a feedback voltage generation circuit(220), and a pulse signal wire(240). A boosting circuit formation region(210_a) and a feedback voltage generation region(220_a) are defined on the substrate. The boosting circuit is installed on the boosting circuit region, and boosts an input voltage to generate an analog voltage and a pulse signal. The feedback voltage generation circuit is installed on the feedback voltage generation region, and provides a feedback voltage to a control chip by using the analog voltage. The pulse signal wire outputs the pulse signal and is spaced apart from the feedback voltage generation circuit.
