Title: DISPLAY APPARATUS AND ELECTRONIC DEVICE
Abstract:
A display apparatus (100, 200) and an electronic device. The display apparatus (100, 200) comprises at least one display panel (10, 10a), at least one concave lens (20, 20a) and at least one convex lens (30, 30a), wherein the display panel (10, 10a) has a display region (11, 11a) for arranging a plurality of pixels and a frame region (12, 12a) arranged at an outer side of the display region (11, 11a); the concave lens (20, 20a) is arranged at an edge of the display region (11, 11a) and is used to radiate a part of light rays emitted from the display region (11, 11a) towards the frame region (12, 12a) side; one side edge of the convex lens (30, 30a) is aligned with an inner side, towards the display region (11, 11a), of the concave lens (20, 20a); after the convex lens (30, 30a) crosses a boundary of the display region (11, 11a) and the frame region (12, 12a), the other side edge of the convex lens is aligned with an edge of the frame region (12, 12a), so as to parallelly emit light rays radiated from the concave lens (20, 20a); and after the concave lens (20, 20a) and the convex lens (30, 30a) are passed, there are parallel emergent light rays at any position of a light-emitting surface of the display apparatus (100, 200). When display apparatuses (100, 200) are applied to a spliced electronic device, seamless display joint of the two display apparatuses (100, 200) can be realized.
