ABSTRACT:
A liquid crystal display module and its scanning circuit board therein. There are a first scanning circuit and a second scanning circuit located at both ends of each of the scanning lines in the LCD panel. While scanning, both the first scanning circuit and the second scanning circuit drive the same scanning line simultaneously, so as to equivalently reduce the delay effect caused by the RC time constant. The first scan driving circuit and the second scan driving circuit could be placed on different scanning circuit boards with the same layout. The scanning circuit board has two connectors at the both ends and a scanning interface at a side. The scanning circuit board could be used at both sides of the LCD panel by the rotation of 180°.
