Description of the drawings
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention, for those of ordinary skill in the art, without having to pay creative labor, according to
These attached drawings obtain other attached drawings and still fall within scope of the invention.
Fig. 1 is that the floor map of Pin Mura phenomenons occurs in liquid crystal display panel in the prior art；
Fig. 2 is the planar structure schematic diagram for the support needle on substrate that the embodiment of the present invention one provides；
Fig. 3 is the planar structure schematic diagram of support element provided by Embodiment 2 of the present invention.
Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with attached drawing
Step ground detailed description.
As shown in Fig. 2, in the embodiment of the present invention one, a kind of support needle on substrate provided, including supporting rod 1
And it is set to the temperature compensation division 2 on supporting rod 1, to automatically control compensation and substrate by temperature compensation division 2（Do not scheme
Show）The temperature in the region being in contact so that temperature energy after the regional compensation being in contact with substrate and with substrate not contact area
Temperature consistent avoid the generation of Pin Mura phenomenons.
In the embodiment of the present invention one, temperature compensation division 2 includes constant temperature portion 21 and adjustment portion 22；Wherein,
Constant temperature portion 21 is fixed on supporting rod 1, is made by phase-change material, and constant model is maintained the temperature to energy storage
Enclose interior variation；
Adjustment portion 22 is wrapped on the outer surface in constant temperature portion 21, is made by organic material or metal material, to base
The temperature in conduction constant temperature portion 21 and adjust compensation after plate is in contact so that temperature after the regional compensation being in contact with substrate and with
The temperature of substrate not contact area is consistent.
It should be noted that the temperature due to constant temperature portion 21 is determined according to phase-change material, it is therefore necessary to adjustment portion
The effective compensation temperature that 22 thickness is adjusted to ensure the region being in contact with substrate can with substrate not contact area
Temperature it is consistent, therefore when phase-change material is low-temperature phase-change material, medium temperature phase-change material, one among high temperature phase change material (pcm)
Kind, the thickness of adjustment portion 22 may also be different.
In one embodiment, phase-change material is low-temperature phase-change material, including but not limited to stearic acid, palmitic acid, paraffin
And lauric acid.In another embodiment, phase-change material is medium temperature phase-change material, including but not limited to MgCl3, LiNO3, KNO3
And NaNO2.In yet another embodiment, phase-change material is high temperature phase change material (pcm), including but not limited to LiOH and Na2CO3.
Energy storage in order to reduce constant temperature portion 21 is supported the absorption of bar 1, therefore supporting rod 1 is made by heat insulator.
Heat in order to further decrease constant temperature portion 21 is conducted to supporting rod 1, it is necessary to reduce the contact surface in constant temperature portion 21 and supporting rod 1
Product, therefore constant temperature portion 21 is set as spheroidal, adjustment portion 22 is wrapped on the outer surface in constant temperature portion 21 at this time, spherical in semicircle.
As shown in figure 3, in the embodiment of the present invention two, a kind of support element provided, including pedestal M and it is set to pedestal
At least one support needle L being used on substrate in the embodiment of the present invention one on M, the support needle L are implemented with the present invention
The structure and connection relation for the support needle on substrate in example one is identical, specifically refers to the use in the embodiment of the present invention one
In the related content of the support needle on substrate, this is no longer going to repeat them.
Implement the embodiment of the present invention, has the advantages that：The support needle set of the present invention has temperature compensation division, to logical
Excess temperature compensation section automatically controls the temperature in the region that compensation is in contact with substrate so that after the regional compensation being in contact with substrate
Temperature energy and the temperature of contact area is not consistent with substrate, to avoid the temperature difference, fundamentally avoid Pin Mura phenomenons
Generation.
It is above disclosed to be only a preferred embodiment of the present invention, the power of the present invention cannot be limited with this certainly
