Abstract
Official abstract text for this publication.
A side-edge backlight module having non-uniformly sized backlight sections and a design method thereof. The backlight module includes backlight sections that have relative sizes satisfying the condition that the backlight sections have higher ranks are of greater sizes. Ranking the backlight sections is made by conducting an simulation operation for a process of sectionalized lighting of backlight to display liquid crystal panel signals on the basis of uniformly sized backlight sections and conducting analysis of the number of zones where an interference signal appears and distance of the interference signal when each of backlight sections is lit in the simulation operation on the basis of uniformly sized backlight sections and ranking the backlight sections according to strength of cross-talking caused by the interference signal so that a backlight section having less strong cross-talking is set with a higher rank.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for designing a side-edge backlight module having non-uniformly sized backlight sections, comprising the following steps: (1) conducting an simulation operation by supplying and displaying liquid crystal panel signals on sections of a liquid crystal panel and activating backlight sections of a backlight module on the basis of uniformly sized backlight sections, wherein the backlight sections are arranged side by side in a first direction to collecti…
