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 touch display apparatus including a body, a display module, a light control element, and a touch module is provided. The body has an opening. The display module is disposed in the body and is suitable for emitting a plurality of image beams toward the opening. The light control element is disposed to overlap the opening of the body and is suitable for reflecting the image beams coming from the display module to an imaging space to display an image frame of the display module. The imaging space and the display module are located on two opposite sides of the light control element. The touch module is disposed on one side of the light control element and is configured to recognize a touch operation of a user in the imaging space.
