Title:
BACKLIGHT MODULE AND DISPLAY DEVICE II
Document Type and Number:
WIPO Patent Application WO/2023/133687
Kind Code:
A1
Abstract:
A display device includes a display panel, a first light source, and second light source. The first and second light sources are respectively aligned with a first spot and second spot in a direction perpendicular to a substrate. The first light source irradiates the first and second spots with luminance of a first value and second value, respectively. The first light source irradiates a midpoint between the first and second spots with a luminance value that is half the addition of the first and second values.
