Abstract
A light adjusting structure is disposed between a light source in a device and a light exiting surface of the device. The light adjusting structure includes at least one visible light absorbing pattern defining a plurality of light-transmitting regions, and a ratio of a thickness of the at least one visible light absorbing pattern to a width of one of the light-transmitting regions is greater than or equal to 0.5, and a vertical projection of the at least one visible light absorbing pattern presents a checkerboard pattern or a mesh pattern.

A device, comprising:
- a light source;
- and
- a light adjusting structure, disposed between the light source and a light exiting surface of the device, the light adjusting structure comprising:
- at least one visible light absorbing pattern, defining a plurality of light-transmitting regions, wherein a ratio of a thickness of the at least one visible light absorbing pattern to a width of one of the light-transmitting regions is greater than or equal to 0.5, and a vertical projection of the at least one visible light absorbing pattern presents a checkerboard pattern or a mesh pattern, and the width of the one of the light-transmitting regions is between 5 microns and 1,000 microns, and the light source is aligned with a portion of the at least one visible light absorbing pattern and some of the light-transmitting regions defined by the portion of the at least one visible light absorbing pattern.
