Cambered surface lens and manufacturing method thereof

Abstract

The invention relates to a cambered surface lens which comprises a first substrate and a second substrate. The inner side surface of the first substrate is a plane, the outer side surface of the first substrate comprises a middle plane and an edge cambered surface, the second substrate is a plane substrate, a touch induction circuit layer is arranged on the inner side surface of the second substrate, and the outer side surface of the second substrate is attached on the inner side surface of the first substrate through a transparent adhesive layer. As the cambered surface lens is set into a double-layer structure, the edge of the second substrate does not need to be polished into a cambered surface, the second substrate can be a transparent plate with fine impact resistance, a joint between the cambered surface lens and a shell can have high strength, the impact applied on the surface of the cambered surface lens can be buffered by the transparent adhesive layer, the stress at the joint between the cambered surface lens and the shell is reduced, and the cambered surface lens has fine impact resistance. As the second substrate is the plane substrate, the touch induction circuit layer is set according to an existing process, a common flat display instead of an embedded touch display can be selected, and cost is reduced.

Description

technical field [0001] The invention relates to the field of touch display, in particular to a curved lens for a touch display and a manufacturing method thereof. Background technique [0002] At present, some electronic products (mainly mobile phones) with 2.5D curved screens appear on the market. The touch control display screen of this 2.5D curved screen is a curved lens, such as figure 1 As shown, the surface of the curved lens 01 includes a middle plane 02 in the middle, and an edge curved surface 03 at the periphery. Since the periphery is a curved surface, it is more beautiful. On the periphery of the curved lens 01, the edge curved surface 03 can also The black border of the display is hidden through a certain refractive effect to achieve a visual borderless effect. [0003] At present, such a touch display screen with a curved lens generally includes a flat panel display 04 and a curved lens 01, the curved lens 01 is attached to the outer surface of the flat panel ...

AI Technical Summary

Problems solved by technology

[0005] At present, the general process of batch production of touch screens is: to make multiple touch sensing units on a large flat substrate, and then separate them to form a single touch screen, so as to realize the mass production of touch screens. If the edge of a single touch screen after mass production is polished into an arc However, if the edge of a single flat substrate is polished into a curved surface first, and then the touch sensing unit is manufactured, it is obvious that it can only be manufactured individually, and mass production cannot be realized.

[0006] Therefore, the display of this touch display screen with curved lenses needs to adopt a higher price embedded touch display (that is, a display integrated with a touch function), which has led to this touch display with curved lenses. The overall cost of the screen is higher
