Specific embodiment
To improve the display bad phenomenon at display panel edge, display quality is improved, the utility model embodiment provides
A kind of mask plate.It is new to this practicality by the following examples to make the purpose of this utility model, technical solution and advantage clearer
Type is described in further detail.
As shown in Figures 2 and 3, the mask plate 10 that the utility model embodiment provides, in ultra-violet curing sealant
The display area 21 of display panel 20 is blocked, including corresponding the more of setting with each display panel 20 on motherboard panel 200
A mask unit 11, each mask unit 11 include shading region 12 and the partial light permeability area 13 set around shading region, shading region
12 are used to block the display area 21 of display panel 20 and match with 21 shape of display area of display panel 20.
The mask plate 10 provided using the utility model embodiment, since each mask unit 11 includes shading region 12 and ring
The partial light permeability area 13 set around shading region 12, therefore the gap between the shading region 12 of adjacent mask unit 11 can be more than portion
Divide the gap between transparent area 13, when ultraviolet light is irradiated to by mask plate 10 on motherboard panel 200, pass through adjacent mask
Diffraction phenomena can occur during gap between the partial light permeability area 13 of unit 11, therefore adjacent mask unit 11 is rationally set
Gap between partial light permeability area 13 can make the range of exposures of the light after diffraction still be limited in corresponding two display surfaces
Between the display area 21 of plate 20, that is, the light after diffraction is avoided to be irradiated to the display area 21 of display panel 20, while through portion
The light intensity of transparent area transmission 13 is divided also to disclosure satisfy that the requirement light intensity for curing sealant 22, compared with prior art, the program
On the premise of it can fully cure sealant 22, can also weaken the display area 21 of display panel 20 is influenced by illumination,
Therefore the display bad phenomenon at 20 edge of display panel can be improved, improve display quality.
It should be noted that using during mask plate 10, it is necessary to will be set between mask plate 10 and motherboard panel 200 certain
Distance, in order to avoid array substrate and color membrane substrates friction misalignment or the table to display panel that high-precision is bonded by mask plate 10
It causes to wear in face.Specifically, the distance can be arranged to 100mm~200mm.The partial light permeability area of adjacent mask unit 11
Gap between 13 needs to be determined according to the installation position of light source, for example, when light source positional distance mask plate 10 farther out when, can
So that the gap between the partial light permeability area 13 of adjacent mask unit 11 is more relatively large, when the positional distance mask of light source
When plate 10 is nearer, the gap between the partial light permeability area 13 of adjacent mask unit 11 can be made more relatively small.
In the preferred embodiment of the utility model, the uv transmittance in partial light permeability area is 15% ± 1%.The application
Utility model people drawn through overtesting, when the transmitance in partial light permeability area is about 15%, can meet sealant curing want
The light intensity asked.
The specific constructive form of mask plate is unlimited, and in one embodiment of the utility model, mask unit is individual layer knot
Structure at this point it is possible to choose material of the metal material as shading region, allows shading region preferably to block ultraviolet light, avoids light
Line is directed to the display area of display panel；The material that tin indium oxide material is partial light permeability area, tin indium oxide pair are chosen simultaneously
The absorptivity of ultraviolet light is not less than 85%, so as to meet the uv transmittance requirement in partial light permeability area, and then meets solid
Change the requirement of sealant.
As shown in figure 3, in another embodiment of the utility model, mask unit 11 is 14 He of metal layer being stacked
Indium tin oxide layer 15, the region Chong Die with metal layer 14 of indium tin oxide layer 15 are shading region, and indium tin oxide layer 15 exceeds metal layer
The region at 14 edges is partial light permeability area.That is, the shading region of mask unit 11 is metal layer 14 and indium tin oxide layer 15
Stacked double-layer structure, can be directed to the display area 21 of display panel to avoid light, and partial light permeability area is tin indium oxide material
The single layer structure of matter, uv transmittance disclosure satisfy that the requirement for curing sealant.At this point, metal layer 14 and indium tin oxide layer
15 connection mode is unlimited, it is preferred that can be connected by viscose glue.
It, can be with when using mask plate when mask unit 11 is the metal layer 14 and indium tin oxide layer 15 being stacked
Metal layer 14 is made to be located towards the one side of motherboard panel 200, metal layer 14 can also be made to be located at one backwards to motherboard panel 200
Side, this is not restricted.
In the preferred embodiment of the utility model, the thicknesses of layers in partial light permeability area is 500 angstroms~800 angstroms.By setting
Its uv transmittance can be controlled by putting rational tin indium oxide thicknesses of layers, and the utility model people of the application obtains through overtesting
Go out, when thicknesses of layers is above-mentioned value, the uv transmittance in partial light permeability area is about 15%, can meet and cure sealant
It is required that.
As shown in Fig. 2, during using mask plate 10, for each mask unit 11, partial light permeability area 13 is in corresponding display
Projection on panel 20 is located in the region that sealant 22 is confined.Using the embodiment scheme, the light after diffraction is avoided shines
On the premise of the display area 21 for being mapped to display panel 20, part sealant 22 is also enable to be subject to by adjacent mask unit 11
Partial light permeability area 13 between the direct projection of ultraviolet light that passes through of gap, so as to improve the solidification effect of sealant 22.It is worth one
It is mentioned that, since sealant 22 has certain width, in the utility model embodiment, the region that sealant 22 is confined represents
The area maximum region confined by the outmost turns of sealant 22.
Obviously, those skilled in the art can carry out the utility model various modification and variations without departing from this practicality
New spirit and scope.If in this way, these modifications and variations of the utility model belong to the utility model claims and
Within the scope of its equivalent technologies, then the utility model is also intended to comprising including these modification and variations.
