The present application may repeat reference numerals and/or letters in the various examples, which have been repeated for purposes of simplicity and clarity and do not in themselves dictate a relationship between the various embodiments and/or arrangements discussed. The curing device of the present application will be described in detail with reference to specific embodiments.
Referring to fig. 1-2, a curing apparatus 100 according to the present application includes: the ultraviolet light source comprises an ultraviolet light source 1 and a wavelength conversion film 2, wherein the wavelength conversion film 2 can be configured in the light outgoing direction of the ultraviolet light source 1 to convert ultraviolet light emitted by the ultraviolet light source 1 into visible light. And the ultraviolet light source 1 corresponds to the position of the frame glue 63 of the liquid crystal display panel 6. Because the flexible display is in the actual curing process of the sealant 63, the flexible substrate absorbs ultraviolet light strongly, so that the ultraviolet light penetrating through the flexible substrate is little, the sealant 63 cannot be cured quickly, and the sealant 63 is often punctured abnormally. Therefore, the wavelength conversion film 2 is configured in the light emitting direction of the ultraviolet light source 1, the wavelength conversion film 2 is used for converting the ultraviolet light emitted by the ultraviolet light source 1 into visible light, and the frame glue 63 is cured by the visible light passing through the flexible substrate, so that the frame glue 63 can be cured quickly, and the phenomenon of abnormal puncture of the frame glue 63 is avoided.
Referring to fig. 3, in the present embodiment, the wavelength conversion film 2 includes a transparent substrate 20 and a quantum dot layer 22 on one side surface of the transparent substrate 20. Referring to fig. 2, the wavelength conversion film 2 of the present invention further includes a quantum dot defining layer 23 on the transparent substrate 20, the quantum dot defining layer 23 forms a grid structure 230 on the transparent substrate 20, the quantum dot layer 22 includes a plurality of quantum dot units 220, each quantum dot unit 220 is located in a corresponding grid, and the thickness of the quantum dot layer 22 is not greater than the thickness of the quantum dot defining layer 23. The quantum dot layer 22 may be formed by inkjet printing, and quantum dots of different materials may be inkjet-printed according to a desired wavelength range of visible light. The wavelength conversion film 2 can be a flexible substrate or a glass substrate, if the flexible substrate is used, the bendable characteristic of the wavelength conversion film 2 can be realized, the thickness of the flexible wavelength conversion film 2 ranges from 80 microns to 100 microns, the thickness of the quantum dot layer 22 is 30-50 microns, and the thickness of the transparent flexible substrate ranges from 50 microns to 60 microns. In the case of a glass substrate, the wavelength conversion film 2 has a thickness in the range of 500-600 microns, the quantum dot layer 22 has a thickness in the range of 30-50 microns, and the glass substrate has a thickness in the range of 450-550 microns. The quantum dot film layer within the thickness range can well convert ultraviolet light into visible light.

That is, in the case where the ultraviolet light source 1 is in the shape of a lamp tube, the wavelength conversion film 2 is bent into a semi-circular ring shape to receive ultraviolet light emitted from the ultraviolet light source 1.
In this embodiment, the transparent substrate 20 is a square frame, since the light emitted from the ultraviolet light source 1 is directed to all directions, in order to avoid the light from being incident on the display area 60 to affect the alignment of the liquid crystal in the display area 60, the curing device 100 may be used with the metal mask 5 in practical use, that is, a metal mask 5 is disposed between the ultraviolet light source 1 and the display panel 6, so that the light emitted from the ultraviolet light source 1 is only used for curing the sealant 63, and in the display area 60, the light is not incident on the display area 60 due to the blocking of the metal mask 5. That is, the display panel 6 includes an array substrate 65, a color filter substrate 64, and a liquid crystal layer 66 located between the remaining color filter substrates 64 of the array substrate 65, and since liquid crystals in the liquid crystal layer 66 are not aligned yet, they cannot be irradiated by ultraviolet light, so the metal mask 5 is disposed in the direction of the display area 60, and light incident on the surface of the metal mask is reflected by the metal mask 5.
In this embodiment, the curing device 100 further includes a reflective film 3, and the reflective film 3 can be configured in a light emitting direction away from the ultraviolet light source 1, so as to reflect a part of light emitted by the ultraviolet light source 1 to the direction of the sealant 63. In some of the implementations of the invention, the reflective membrane 3 is arc-shaped.
In the present embodiment, the wavelength conversion film 2 can be configured to be located in the light outgoing direction of the ultraviolet light source 1 and can be turned over to the side of the reflection film 3 away from the ultraviolet light source 1 or directly removed when the wavelength conversion film 2 is not needed to convert the ultraviolet light source 1.

Referring to fig. 6 to 7, fig. 6 to 7 show a curing apparatus 300 according to a third embodiment of the present invention, the curing apparatus 300 according to the third embodiment is substantially the same as the curing apparatus 100 according to the second embodiment, except that the curing apparatus 300 further includes a transparent adjusting member 4 located in the light emitting direction of the ultraviolet light source 1, and the wavelength conversion film 12 is located on one surface of the transparent adjusting member 4. The wavelength converting membrane 12 can be located on the inner or outer surface of the transparent adjustment member 4. The wavelength conversion film 12 can be formed on one surface of the transparent adjustment member 4 by being attached thereto because it can be bent.
Preferably, the transparent adjusting member 4 is arc-shaped and can rotate relative to the uv light source 1 to be located on the same side of the uv light source 1 as the reflective film 3. More preferably, the transparent adjustment member 4 is a hollow cylinder, the ultraviolet light source 1 is located inside the adjustment member, the transparent adjustment member 4 is divided into an upper ring portion and a lower ring portion, the wavelength conversion film 12 is located on a surface of one of the upper ring portion and the lower ring portion of the transparent adjustment member 4, and the transparent adjustment member 4 can rotate relative to the ultraviolet light source 1.

In this embodiment, the thickness of the inner cylinder 40 and the thickness of the outer cylinder 42 are both between 1 mm and 5 mm, and the thickness of the inner cylinder 40 and the thickness of the outer cylinder 42 may be the same.
In other embodiments, the transparent adjusting member 4 may also be a semi-circular ring, and two ends of the semi-circular ring are connected to the fixing base, so that the inner semi-cylinder and the outer semi-cylinder can rotate relative to the fixing base respectively. Alternatively, one of the inner cylinder 40 and the outer cylinder 42 of the transparent adjustment member 4 is a semi-circular ring, and the other is a cylinder.
It is understood that the inner cylinder 40 and the outer cylinder 42 of the transparent adjustment member 4 may have other shapes as long as it can ensure that the wavelength conversion film 12 can be turned over to the side of the reflection film 3 away from the ultraviolet light source 1 when not in use.
