Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.It is understood that herein
Described specific embodiment is used only for explaining the utility model, rather than the restriction to the utility model.Further need exist for
It is bright, for the ease of description, part relevant with the utility model rather than entire infrastructure are illustrate only in attached drawing.
Fig. 1 is a kind of structure diagram for display panel that the utility model embodiment provides, referring to Fig. 1, the display surface
The concrete structure of plate is as follows：
Non-display area 120 including display area 110 and around display area 110；
It is arranged at the first encapsulating structure 130 and the second encapsulating structure 140 of non-display area 120, the first encapsulating structure 130
Positioned at the second side of the encapsulating structure 140 away from display area 110；
Wherein, the material hardness of the first encapsulating structure 130 is more than the material hardness of the second encapsulating structure 140.
Display area 110 forms the boundary line 100 of closing with non-display area 120, positioned at the first envelope of non-display area 120
Assembling structure 130 is set with the second encapsulating structure 140 around boundary line 100.
In Fig. 1, exemplarily, the boundary line 100 that display area 110 is formed with non-display area 120 is rectangle, this is only
It is a specific example of the utility model, rather than the limitation to the utility model, optionally, boundary line 100 can also be circle
Shape, polygon etc..
In Fig. 1, exemplarily, each several part of the first encapsulating structure 130 is equal with the distance of boundary line 100, the second envelope
The each several part of assembling structure 140 is equal with the distance of boundary line 100, this is only a specific example of the utility model, rather than right
The limitation of the utility model.
The technical solution of the present embodiment, the first encapsulating structure 130 and the are set by the non-display area 120 in display panel
Two encapsulating structures 140, since the material hardness of the first encapsulating structure 130 is more than the material hardness of the second encapsulating structure 140,
Less second encapsulating structure 140 of hardness can discharge the stress of larger the first encapsulating structure 130 accumulation of hardness, solve aobvious
Show when panel is hit at encapsulating structure the problem of cracky；And since the first encapsulating structure 130 is located at the second encapsulating structure
140 sides away from display area 110, avoid in 130 solidification process of the first encapsulating structure to the damage of 110 element of display area
Wound, such as the first encapsulating structure 130 are cured by laser, can produce substantial amounts of heat in the curing process, so a large amount of
Heat can be delivered in the display element of display area 110, the present embodiment passes through in the first encapsulating structure 130 close to aobvious
Show that the side in region 110 sets the second encapsulating structure 140, can stop or reduce the first envelope by the second encapsulating structure 140
Damage of the heat produced in 130 solidification process of assembling structure to display element in display area 110, improves the reliable of display panel
Property；Meanwhile be used in combination by the first encapsulating structure 130 and the second encapsulating structure 140, the envelope of whole display panel can be strengthened
Characteristic is filled, further avoids steam or oxygen from causing to corrode to the display element set in display area 110.To sum up, this reality

System, other satisfactory encapsulating structures are also within the protection scope of the present utility model.
Frit is used as the first encapsulating structure 130 after laser curing, has the energy of preferable water vapor and oxygen invasion
Power, but its hardness is larger, stress concentration easily ruptures when Frit；UV glue is through ultraviolet light solidify afterwards as the second envelope
Assembling structure 140, since its hardness is smaller than Frit, it is possible to the effect of the stress accumulated on the first seal structure 130 of release is played,
Avoid the problem that display panel is easily ruptured in the case where being subject to external force collision.Simultaneously as UV glue will not produce in the curing process
Raw substantial amounts of heat, so, the material using UV glue as the second encapsulating structure 140 can not only absorb the first encapsulating structure 130
The heats that are produced during laser sintered of material Frit, and itself will not cause display area in the curing process
110 element damage.In addition, also there is the ability of certain water vapor and oxygen invasion after UV adhesive curings, therefore in this way
Setting can also play auxiliary encapsulation effect.
