Title:
BACKLIGHT MODULE AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/059644
Kind Code:
A1
Abstract:
A backlight module (100) and display device (300). The backlight module (100) comprises a light source (120), a light guide plate (140) and a dimming element (160). A light ray produced by the light source (120) can be utilized to measure the chromaticity of the light source. The light guide plate (140) has a light entry surface (141) and a light exit surface (143). A light ray produced by the light source (120) passes through the light entry surface (141), enters the light guide plate (140), and exits from the light exit surface (143). When the dimming element (160) is present, the light exit surface (143) of the light guide plate (140) can be utilized to measure a chromaticity of a first light guide plate. The chromaticity of the first light guide plate and that of the light source have a first difference therebetween. In contrast, when the dimming element (160) is not present, the light exit surface (143) of the light guide plate (140) can be utilized to measure a chromaticity of a second light guide plate, and the chromaticity of the second light guide plate and that of the light source have a second difference therebetween. The first difference is different from the second difference.
