技術說明

一種彩色濾光片包含一第一濾光元件以及一第二濾光元件。第一濾光元件包含多個陣列排列之濾光區域，其用以透射一入射光之一第一光譜組成並反射入射光之其它光譜組成。第二濾光元件包含多個陣列排列之濾光區域，其用以透射入射光之一第二光譜組成並反射入射光之其它光譜組成。第二濾光元件之濾光區域之中心偏離第一濾光元件之濾光區域之中心，以使第一濾光元件所反射的光線可從第二濾光元件透射出去，進而提升彩色濾光片之能量效率。同時亦揭露一種包含上述彩色濾光片之側光式背光模組。 A color filter comprises a first filter element and a second filter element. The first filter element includes a plurality of arrayed filter regions allowing a first spectral component of incident light to pass and reflecting other spectral components of the incident light. The second filter element includes a plurality of arrayed filter regions allowing a second spectral component of the incident light to pass and reflecting other spectral components of the incident light. The center of the filter regions of the second filter element is deviated from the center of the filter regions of the first filter element so that the light reflected from the first filter element can pass through the second filter element. Thereby is enhanced the energy efficiency of the color filter. An edge-type backlight module using the abovementioned color filter is also disclosed.
