Abstract:
A lens, a lens array, a display module, and a display apparatus. The lens comprises: a lens main body (311) and a light-emitting member (312). The lens main body (311) is a conical housing having an inner cavity, the light-emitting member (312) being provided at a first end of the lens main body (311). A first quadratic surface (313) is provided in the inner cavity of the lens main body (311), and a second quadratic surface (314) is provided on the inner wall of the lens main body (311), the first quadratic surface (313) being convex towards the first end of the lens main body (311), the second quadratic surface (314) being convex towards a second end of the lens main body (311), the first end of the lens main body (311) and the second end of the lens main body (311) being the two opposite ends of the lens main body (311), and the second end of the lens main body (311) being the end of the lens main body (311) for emitting a light ray. After being refracted by the first quadratic surface (313), a light ray within the first incident angle range emitted by the light-emitting member (312) is collimated and emitted from the second end of the lens main body (311); and after being reflected by the second quadratic surface (314), an incident light ray within the second incident angle range emitted by the light-emitting member (312) is collimated and emitted from the second end of the lens main body (311).
