Abstract: An optical sensing module, including a frame, a light sensing element, and a diffusion element is provided. The light sensing element is disposed on the frame. The diffusion element is connected to the frame and is disposed above the light sensing element. In a first sensing mode, ambient light passes through the diffusion element before received by the light sensing element to make the optical sensing module to obtain light intensity of the ambient light. In a second sensing mode, the optical sensing module rotates around a first rotation axis to make the light sensing element face a display surface of the display device for receiving image light of the display surface so that the optical sensing module obtains brightness or chromaticity of the display device. A display device having this optical sensing module is also provided.

Abstract: A display apparatus includes a light guide plate, a first light source, a second light source, multiple first optical microstructures, multiple second optical microstructures, and a display panel. The first light source and the second light source are disposed beside a first light incident surface and a second light incident surface of the light guide plate respectively. Multiple second light beams emitted from the second light source irradiate a display surface of the display panel after being reflected by multiple second light receiving surfaces of the second optical microstructures disposed on a second light emitting surface of the light guide plate. Multiple first light beams emitted from the first light source exit the display apparatus after being reflected by multiple first light receiving surfaces of the first optical microstructures disposed on a first light emitting surface of the light guide plate.
