Problems solved by technology

[0005] However, when the display device 4 is slightly deformed, an obstacle 5 will be formed to block a part of the above-mentioned parallel rays. At this time, the water glue or optical glue in area A can be irradiated by ultraviolet light, while the water glue or optical glue in area B The optical glue cannot be irradiated by ultraviolet light, so the water glue or optical glue in area B cannot be cured and overflows from the display device, resulting in glue overflow

Embodiment Construction

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the curing lamp provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] figure 2 The structural diagram of the curing lamp provided by the embodiment of the present invention. see figure 2 , the curing lamp includes a light source 102 and a lampshade, wherein the light source 102 is used to provide light for curing the water glue or optical glue in the display device, such as an ultraviolet lamp. The light source 102 is generally a point light source, or other structures such as strips can also be used according to specific conditions.

[0023] The lampshade is used for reflecting the light emitted by the light source 102 and making the reflected light radiate toward the object 200 to be irradiated. The overall structure of the lampshade is a shell provided outside the light source 102 ...

Abstract

The invention provides a curing lamp which comprises a light source and a lampshade, wherein the lampshade is composed of a bottom reflecting surface and edge reflecting surfaces; the bottom reflecting surface is arranged on one side, away from an illuminated object, of the light source and is a hemispherical curved surface; and the edge reflecting surfaces are arranged surrounding the periphery of one side, facing the illuminated object, of the light source and are connected with the bottom reflecting surface. According to the curing lamp provided by the invention, lights can bypass an obstacle formed by slight deformation of a display device so as to prevent glue from overflowing, the strength of the lights can also be improved, the scattering angle of the lights can be increased, and the uniformity of lights emitted from different angles can be improved, thus the curing effect can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a curing lamp. Background technique [0002] The full lamination technology uses water glue or optical glue to completely paste the panel and the touch screen together in a seamless manner. This technology has a better display effect than the frame paste method. Ultraviolet curing (UV curing) is a very important process in the full lamination process. [0003] In the process of UV curing the display device, due to the blocking of the black matrix, the water glue or optical glue below it cannot be directly irradiated by ultraviolet light. Therefore, ultraviolet light needs to be irradiated from the side of the display device to make the black matrix Water glue or optical glue cures. [0004] Such as figure 1 Shown is the structural diagram of the existing curing lamp. The curing lamp includes a light source 1 and a lampshade, wherein the lampshade is used to reflect t...
