Abstract: A display module includes a backlight module, a liquid crystal layer disposed on the backlight module, and a first light-expanding layer disposed on the liquid crystal layer. The backlight module provides a surface light source. The surface light source forms an image light through the liquid crystal layer, and the first light-expanding layer increases the viewing angle range of the image light along a first direction. The first light-expanding layer substantially extends along a virtual plane, the first direction is perpendicular to the normal of the virtual plane, and a second direction is perpendicular to the first direction and the normal of the virtual plane. The light intensity at the 60-degree viewing angle of the surface light source along the first direction is lower than the light intensity at the 60-degree viewing angle of the surface light source along the second direction.

Abstract: The present invention provides a backlight module, including a bottom plate, a plurality of light sources disposed on the bottom plate, one or more light regulation devices, and an optical film. The light regulation device is disposed on the bottom plate and covers at least one light source. Light generated by the light source is emitted out to reach the light regulation device, and the light regulation device regulates the light. The optical film is disposed on a side, opposite to the light source, of the light regulation device. By adjusting the sizes of a distance between the light sources, the width W of a top surface of the light regulation device, and a vertical distance OD between the bottom plate and the optical film, and relationships therebetween, light emitting uniformity of the backlight module can be improved; or a light field generated by the backlight module can be relatively easily fine-tuned by adjusting pattern distribution of light emitting windows on the top surface, to achieve the effect of uniformization.
