Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
In the related art, after the array substrate and the color film substrate are subjected to box matching, the array substrate and the color film substrate subjected to box matching need to be firstly placed in an ultraviolet irradiation chamber for light curing, and the array substrate and the color film substrate subjected to box matching need to be firstly placed in a constant temperature chamber for heat curing, so that the process of curing the frame sealing adhesive is complex, and the efficiency of manufacturing the liquid crystal display panel is low. The embodiment of the invention provides a curing device which can simplify the process of curing frame sealing glue and further improve the manufacturing efficiency of a liquid crystal display panel.
Fig. 1 is a schematic structural diagram of a curing apparatus according to an embodiment of the present invention, and as shown in fig. 1, the curing apparatus 0 may include: a light source assembly 01 and a mask plate 02.
Wherein, the mask plate 02 sets up on the light-emitting direction of light source subassembly 01, and light source subassembly 01 is used for through the mask plate 02 to waiting that the frame sealing glue of solidification (not shown in figure 1) transmits target light, and target light includes: infrared light and ultraviolet light.
In summary, in the curing device provided in the embodiment of the invention, the light source assembly can emit infrared light and ultraviolet light to the frame sealing adhesive through the mask plate at the same time, so that when the frame sealing adhesive is cured, only the array substrate and the color film substrate after being boxed are cured through one curing device, and light curing (ultraviolet light irradiation realization) and heat curing (infrared light irradiation realization) of the frame sealing adhesive can be realized. Therefore, the process of curing the frame sealing glue is simplified, and the manufacturing efficiency of the liquid crystal display panel is improved.
In addition, in the related art, after ultraviolet light is irradiated to the frame sealing adhesive, the frame sealing adhesive is still in a state of incomplete curing in the process of moving the array substrate and the color film substrate which are boxed into the infrared light irradiation chamber, and in the process, the frame sealing adhesive and liquid crystals in the display panel are diffused mutually, so that the liquid crystals are polluted and leaked. In the embodiment of the invention, the light source component can emit ultraviolet light and infrared light, so that the curing device can perform photocuring and thermocuring on the frame sealing glue at the same time, and the array substrate and the color film substrate after box packing do not need to be moved, so that the mutual diffusion of the frame sealing glue and the liquid crystal is avoided, and the pollution and the leakage of the liquid crystal are avoided.
Fig. 2 is a schematic structural diagram of another curing device according to an embodiment of the present invention, as shown in fig. 2, on the basis of fig. 1, a mask plate 02 may be disposed in parallel on a side of a display panel X where a frame sealing adhesive 03 is located, where it should be noted that the display panel X has a display area and a non-display area located at a periphery of the display area, and the display area is also referred to as AA (english: ActiveArea). The irradiation area of the target light on the display panel X does not overlap the display area of the display panel X.
It should be noted that, in the related art, when the frame sealing adhesive is irradiated with the ultraviolet light, the ultraviolet light is usually irradiated to the display area of the display panel, and at this time, the ultraviolet light may cause a change of a structure in the display area of the display panel, thereby affecting the display effect of the display panel. In the related art, when infrared light is irradiated to the frame sealing glue, the infrared light is also irradiated to the frame sealing glue and the display area of the display panel, so that the frame sealing glue and the liquid crystal are mutually diffused under the action of the infrared light, and further pollution and leakage of the liquid crystal are caused. In the embodiment of the invention, since the irradiation area of the light (i.e., the target light) emitted by the light source assembly on the display panel is not overlapped with the display area, neither the ultraviolet light nor the infrared light can irradiate the display area of the display panel, so that the influence of the ultraviolet light on the display area to the display effect of the display panel is prevented, and the mutual diffusion of the frame sealing glue and the liquid crystal is prevented.
Alternatively, in the embodiment of the present invention, the infrared light emitted by the light source assembly 01 may propagate along the first direction Y1, and the ultraviolet light emitted by the light source assembly 01 may propagate along the second direction Y2 and the third direction Y3. The first direction Y1 may be perpendicular to the panel surface B of the mask 02 (and perpendicular to the display panel X), an included angle α 1 between the second direction Y2 and the first direction Y1 is a first acute angle, and an included angle α 2 between the third direction Y3 and the first direction Y1 is also a first acute angle. The second direction Y2 is different from the third direction Y3.
With continued reference to fig. 2, the light source assembly 01 may include: an infrared light source 011, a first ultraviolet light source 012, and a second ultraviolet light source 013. The first ultraviolet light source 012 and the second ultraviolet light source 013 may be respectively disposed on a side of the infrared light source 011 close to the display area and a side far from the display area in the display panel X. It should be noted that the mask plate 02 may have a light hole Z, and the light source assembly 01 is configured to emit target light to the frame sealing adhesive 03 through the light hole Z, that is, the target light may pass through the light hole Z and emit to the frame sealing adhesive 03. The infrared light source 011 is used for emitting infrared light to the frame sealing glue 03 through the light-transmitting holes Z; the first ultraviolet light source 012 is configured to emit ultraviolet light propagating along the second direction Y2 to the frame sealing adhesive 03 through the light-transmitting hole Z; the second ultraviolet light source 013 is configured to emit ultraviolet light propagating along the third direction Y3 to the frame sealing adhesive 03 through the light-transmitting hole Z.
It should be noted that the light emitted by each light source (e.g., the infrared light source, the first ultraviolet light source, and the second ultraviolet light source) in the light source module propagates along a fixed direction, that is, a plurality of light emitted by each light source are parallel to each other. As shown in fig. 3, each light source may include: the light source device comprises a light source body 30 and an optical element 41 arranged in the light outgoing direction of the light source body 30, wherein the light source body 30 is used for emitting scattered light, and the optical element 41 is used for changing the scattered light emitted by the light source body 30 into light which is transmitted along a fixed direction. Illustratively, the optical element 41 may be a concave structure as shown in fig. 3, which has a concave surface 411 close to the light source body 30, and a convex surface 412 far from the light source body 30. The light source body 30 may be disposed at a focal point of the concave structure, and may be manufactured according to a relationship among a focal length F of the concave structure, a refractive index N of the concave structure, a radius of curvature R1 of a concave surface in the concave structure, and a radius of curvature R2 of a convex surface, that is, 1/F ═ (N-1) (1/R1+ 1/R2). In practical applications, the concave structure in each light source may also be other structures capable of converting scattered light into parallel light, such as a convex lens.
It should be further noted that, in fig. 2, the first ultraviolet light source and the second ultraviolet light source are respectively disposed at two sides of the infrared light source, and the infrared light source, the first ultraviolet light source and the second ultraviolet light source are disposed side by side, for example, in practical application, as shown in fig. 4, distances between the first ultraviolet light source 012 and the second ultraviolet light source 013 and the mask plate 02 may be the same, and both may be smaller than the distance between the infrared light source and the mask plate 02.
Further, since the frame sealing adhesive is generally in a square frame shape, at this time, as shown in fig. 5, the mask plate 02 in the curing apparatus has a hollow area (e.g., a rectangular hollow area) similar to the shape of the frame sealing adhesive. As shown in fig. 6, the curing apparatus may include a plurality of light source assemblies (not shown in fig. 6), which are arranged in a square frame shape. Wherein, each light source component can also comprise two ultraviolet light sources and one infrared light source.
The irradiation area of the infrared light on the display panel X is located within the irradiation area of the ultraviolet light on the display panel X. For example, an irradiation area of the infrared light on the display panel X is located in an area where the frame sealing adhesive 03 is located on the display panel X; in the width direction Y4 of the frame sealing adhesive 03, the width of the irradiation region of the infrared light on the display panel X is smaller than the width of the frame sealing adhesive 03. For example, the irradiation area of the infrared light on the display panel X is a partial area of the area where the frame sealing adhesive 03 is located, which is far away from the display area, and the width of the irradiation area of the infrared light on the display panel X may be equal to one half of the width of the frame sealing adhesive 03. The distance between the mask and the display panel may be 7 mm to 8 mm (e.g., 7 mm), and the minimum distance between the opening of the light hole Z near the display panel and the edge of the display area in the display panel may be 0.7 mm.
Therefore, the ultraviolet light emitted by the light source assembly in the embodiment of the invention can irradiate the frame sealing glue in a large area, so that the frame sealing glue is photo-cured, and the infrared light emitted by the light source assembly can thermally cure partial area in the frame sealing glue. Further, since the irradiation range of infrared light is small, the irradiation of infrared light to the display region of the display panel can be further prevented.
Optionally, in order to increase the amount of the target light emitted into the frame sealing adhesive 03 by the light source assembly 01, the opening of the light-transmitting hole Z facing one side of the light source assembly 01 may be set to be larger. That is, the opening area of the light hole Z near the light source assembly 01 side may be larger than the opening area of the light hole Z far from the light source assembly 01 side.
For example, a first portion Z1 of the side wall of the light transmission hole Z far from the display area in the display panel X may be perpendicular to the plate surface of the mask plate, and a second portion Z2 of the side wall of the light transmission hole Z near the display area in the display panel X may be inclined to the first portion Z1. Optionally, in order to increase the amount of the target light emitted from the light source assembly into the sealant, the inclination angle β of the second portion Z2 relative to the first portion Z1 may be greater than the included angle α 1 between the second direction Y2 and the first direction Y1.
It should be noted that the shape of the light-transmitting hole is various, and two shapes of the light-transmitting hole will be exemplified in the embodiment of the present invention. In the first shape of the light-transmitting hole, each cross section (a section perpendicular to the depth direction of the light-transmitting hole) of the light-transmitting hole may be circular, and both openings of the light-transmitting hole may be circular. In a second shape, the side wall of the light-transmitting hole includes four planes connected in sequence, three of the four planes are perpendicular to the plate surface of the mask plate, and the other plane forms an included angle with the plate surface of the mask plate, the included angle is an inclination angle β of the second part Z2 relative to the first part Z1, and the other plane is arranged close to the display region.
In practical application, the first portion and the second portion of the sidewall of the light transmission hole Z may be perpendicular to the plate surface of the mask plate, which is not limited in the embodiment of the present invention.
In summary, in the curing device provided in the embodiment of the invention, the light source assembly can emit infrared light and ultraviolet light to the frame sealing adhesive through the mask plate at the same time, so that when the frame sealing adhesive is cured, only the array substrate and the color film substrate after being boxed are cured through one curing device, and the photo-curing and the thermal curing of the frame sealing adhesive can be realized. Therefore, the process of curing the frame sealing glue is simplified, and the manufacturing efficiency of the liquid crystal display panel is improved.
The foregoing is considered as illustrative of the embodiments of the present application and is not to be construed as limiting thereof, and any modifications, equivalents, improvements and the like made within the spirit and principles of the present application are intended to be included within the scope of the present application.
