As shown in fig. 2, in one embodiment, the housing 100 includes a ceramic substrate 110 and an optical film layer 120. The ceramic substrate 110 includes an outer surface 112 and an inner surface 111 that are oppositely disposed. The optical film layer 120 covers the outer surface 112 of the ceramic substrate 110. The inner surface of the optical film 120 is attached to the outer surface 112 of the ceramic substrate 110, the outer surface of the optical film 120 is the outer surface of the housing 100, and the inner surface 111 of the ceramic substrate 110 is the inner surface of the housing 100. Micro-scale pores are present in a partial region or a whole region of the outer surface 112 of the ceramic substrate 110, so that the roughness of the partial region or the whole region of the outer surface 112 of the ceramic substrate 110 is 10 μm to 500 μm, for example, may be 100 μm, 200 μm, 300 μm, 400 μm, or the like. The optical film layer 120 covers the region with the roughness of 10 μm to 500 μm, and the thickness of the optical film layer 120 is different at different positions. The roughness of the outer surface 112 of the ceramic substrate 110 is 10 μm to 500 μm in a partial region or in the entire region, and is within the scope of the present application. It is understood that the optical film layer 120 is a transparent structure, and the thickness varies in an increasing or decreasing manner along a certain direction, which may be a length direction or a width direction of the housing 100 or other directions, and is not limited herein; alternatively, since the roughness of the outer surface 112 of the ceramic substrate 110 is 10 μm to 500 μm, the micro-pores of the micron order exist on the outer surface 112 of the ceramic substrate 110, and the thickness of the optical film layer 120 is different at different positions due to the micro-pores of the micron order.
