Electronic device, curved surface lens and processing method thereof

Abstract

The invention discloses an electronic device curved surface lens, which comprises a lens body. The edge of the outer surface of the lens body is a curved surface; the inner surface of the lens body comprises an inner platform in the middle part and an outer platform around the inner platform; a fillet groove surrounding the inner platform is arranged between the inner platform and the outer platform; a transfer printing ink layer covering the outer platform, the fillet groove and the peripheral edge of the inner platform is arranged on the inner surface; a spraying ink layer covering the peripheral edge of the transfer printing ink layer is arranged on the transfer printing ink layer; and the inner edge of the spraying ink layer is located in the middle of the inner edge of the transfer printing ink layer and the inner edge of the fillet groove. The phenomenon of light leakage occurring at both sides of a chamfer and the like can be prevented, the production efficiency is improved, and the cost is saved. The invention also discloses an electronic device comprising the above curved surface lens and a processing method for the above curved surface lens.

Description

technical field [0001] The invention relates to the field of lenses, in particular to an electronic device and a curved lens thereof. In addition, the present invention also relates to a processing method of the above-mentioned curved lens. Background technique [0002] Electronic equipment needs to cover the lens to display the content and protect the internal structure. The traditional lens is a flat lens, and its processing technology is simple. Using methods such as silk screen printing or pad printing, black borders are set on the outer peripheral edge of the lens to achieve a black masking effect. With the increasing application of sapphire cover and touch screen, the structure is also becoming more and more complex. 2.5D, 3D and other structural products have appeared one after another and have increasingly penetrated into people's life and work. Especially for products with 3D structure, when it comes to 3D surface concave windows, processing becomes more difficult....

AI Technical Summary

Problems solved by technology

Especially for products with 3D structure, involving 3D surface concave windows, the processing difficulty becomes greater

[0003] In the existing technology, conventional processing methods are used for processing. After the window is pasted with a film, it is directly sprayed. After tearing off the film, there will be missing teeth. The covering effect cannot meet the customer's requirements, and it is easy to cause chamfering and light leakage on both sides of the fillet groove, which cannot be achieved. Covering effect, appearance yield is extremely low
