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 device includes a display panel, a transparent plate and at least one compressible transparent member. The display panel has a display surface. The transparent plate is disposed on the display panel and has a light incident surface and a first light emitting surface opposite to each other. The display surface and the light incident surface face each other, and the transparent plate has at least one side surface connected between the light incident surface and the first light emitting surface. The compressible transparent member is disposed on the side surface and has a second light emitting surface, and the second light emitting surface is tilted relative to the first light emitting surface. Moreover, a display apparatus including a plurality of the display devices is also provided. When the display devices are spliced to form the display apparatus, the problem of visible black lines of splicing seams is mitigated.

Abstract: A display device including a plate, a first display module, a second display module, a first frame and a second frame is provided. The plate has a first surface and a second surface opposite to each other. The first display module and the second display module are disposed on the first surface and the second surface of the plate respectively. A display direction of the first display module and a display direction of the second display module are opposite to each other. The first frame is disposed on the first surface of the plate and surrounds the first display module. The first frame is for carrying the first display module. The second frame is disposed on the second surface of the plate and surrounds the second display module. The second frame is for carrying the second display module. The plate is clamped by the first frame and the second frame.
