EDGE TYPE LED BACKLIGHT AND LIQUID CRYSTAL TELEVISION SET

摘要

PROBLEM TO BE SOLVED: To solve a problem that a liquid crystal module using an edge type LED backlight cannot perform scanning drive for improving a moving picture response.;SOLUTION: Only a group of LED 19a1 to 19a6 are selected to light by scanning signals C1 to C6 obtained by dividing a frequency of a vertical synchronizing signal DE in the sub-scanning direction. Each of the group of LED 19a1 to 19a6 lights corresponding one of light guide plates 19b1 to 19b6 divided in the sub-scanning direction corresponding to each region of the vertical synchronizing signal DE. Thus, scanning lighting which has been impossible in a conventional technology with the edge type LED backlight becomes possisble.;COPYRIGHT: (C)2011,JPO&INPIT
