Embodiment Construction
[0052] For illustrative purposes, Figure 7 In the illustration, only a part of a backlight panel composed of a plurality of light guides will be taken, for example, a total of 9 light guides 90 , 91 . . . 98 adjacent to each other will be described. And the light guide located in the center is numbered 90, and the adjacent light guides located around the light guide 90 are respectively numbered 91, 92...98; each light guide 90, 91...98 is respectively provided with a corresponding LED light source 80, 81. ..88. Taking the light guide 90 as an example, after the light from the LED light source 80 passes through the light guide 90, it may emit light across regions to cause the so-called "Cross-Talk" effect in other regions, and provide different positions for different positions of the front liquid crystal panel. Brightness contribution. In this case, in order to accurately calculate and quantify the contribution, the light guide light rate distribution information D(x, y) is...
