Description
Technical field
The present invention relates to a kind of LCD plate technique, particularly a kind of liquid crystal display panel.
Background technology
For present LCD (Liquid Crystal Display liquid crystal displays) panel, panel is increasingly required
It is frivolous, therefore thinning treatment will be carried out after panel output.Now commonplace way is exactly that glass panel surface is entered
Row acid soak, the mode that then surface polishes again.
LCD, when carrying out thinning and processing, is all first by the big glass-cutting of big generation line into several small Block
The glass of (block) shape, glass surrounding by way of Block Seal (frame glue) is enclosed in coating one, then in Block Seal
Periphery is coated a circle marine glue, and acid solution invades the corruption for causing inside glass when preventing glass in thinning under the protection of two circle glue
Erosion metallic circuit.
During actual LCD processing procedure, vacuum breaker is completed in Block Seal coatings so that the pressure of glass outer layer
The mode of the powerful pressure in inside glass, by layer glass fitting together tightly.But applied in actual Block Seal
During cloth, because the wide cut precision of the corresponding region glue of Block Seal corners is poor, easily there is disconnected glue or frame glue width mistake
Carefully, vacuum breaker moment due to the pressure difference of inside glass it is excessive, be easily rushed to open in these corner area frame glues, occur
Large area is broken.Glass easily occurs outside acid solution when thinning is carried out and enters from the areas of disconnection of glue, causes metallic circuit
Corrosion.Simultaneously as inside glass pressure difference is excessive, easily causes glass and deform upon, cause box thickness ununiformity, influence is normal
Display.
The content of the invention
To overcome the deficiencies in the prior art, the present invention provides a kind of liquid crystal display panel, so as to prevent during thinning in glass
Metallic circuit by acid liquid corrosion.
The invention provides a kind of liquid crystal display panel, including two pieces of glass substrates fitted each other, in glass base
Sub- LCD panel array is placed with plate, the periphery for being located at sub- LCD panel array in two pieces of glass substrates is applied
Frame glue is furnished with, the frame glue includes the first sub- frame being coated with along four outer side edges of the sub- LCD panel array of glass substrate
Glue and it is coated on second sub- frame glue of the glass substrate at four angles of sub- LCD panel array, the first sub- frame
A glue side adjacent with the second sub- frame glue overlaps each other.
Further, adjacent two the first sub- frame glues are mutually not attached to.
Further, the described first sub- frame glue is linear.
Further, the length of the described first sub- frame glue respectively with four length of outer side edges of sub- LCD panel array
Degree is equal.
Further, the described second sub- frame glue is L-shaped.
Further, two edge lengths of the described second sub- frame glue are equal.
Further, the width of the described first sub- frame glue and the second sub- frame glue is equal.
Further, the described second sub- frame glue is located at the inner side of the first sub- frame glue.
Further, the described second sub- frame glue is located at the outside of the first sub- frame glue.
The present invention compared with prior art, first is respectively coated by four sides of sub- LCD panel array
Sub- frame glue, is coated with the second sub- frame glue, the first sub- frame glue and the second sub- frame glue phase at four angles of sub- LCD panel array
Adjacent side is connected with each other so that the second sub- frame glue at four angles is not in disconnected glue or meticulous problem, when preventing thinning
Metallic circuit is by acid liquid corrosion；After the combination of liquid crystal display panel vacuum breaker, the pressure inside and outside glass is consistent, the corresponding type of glass
Variable diminishes, so as to improve the homogeneity of box thickness (Cell Gap).

The periphery of panel array is coated with frame glue 2, and the frame glue 2 is included along the sub- LCD panel array of glass substrate 1
First sub- frame glue 3 of four outer side edges coating and glass substrate 1 is coated on adjacent to four angles of sub- LCD panel array
The second sub- frame glue 4 at place, gap is provided between the first sub- frame glue 3 and four outer side edges of sub- LCD panel array；Institute
The first sub- frame glue 3 side adjacent with the second sub- frame glue 4 is stated to overlap each other.
In the present invention, adjacent two the first sub- frame glues 3 are mutually not attached to, and the first sub- frame glue 3 is linear, its length difference
With four equal lengths of outer side edges of sub- LCD panel array, specifically, due to generally, sub- LCD
Plate array includes two long sides and two short side sides, wherein occupying two first sons of the long side of sub- liquid crystal display panel
The length of frame glue 3 and the equal length of long side, occupy two length of the first sub- frame glue 3 on the short side side of sub- liquid crystal display panel
Degree and the equal length on short side side；Second sub- frame glue 4 is L-shaped, and two edge lengths are equal, and specifically two length on side are not
More than one in sub- LCD panel array 1/2nd of the short side of sub- liquid crystal display panel, the second son is so ensure that
The sub- frame glue 3 of frame glue 4 and first has enough overlapping regions.
Used as a preferred embodiment of the present invention, the width of the first sub- frame glue 3 and the second sub- frame glue 4 is equal.
In the present invention, the both sides of the second sub- frame glue 4 overlap together with two adjacent parts of the first sub- frame glue 3 respectively,
Such benefit is to ensure that the part between the first sub- frame glue 3 and the second sub- frame glue 4 in the absence of gap or disconnection.
Used as a kind of preferred scheme of the second sub- frame glue 4, the angle between the both sides of the second sub- frame glue 4 is right angle, both sides
Connecting place can be tightr with what the four of sub- LCD panel array angles were fitted.
Embodiment 1：
As shown in figure 1, four groups of sub- LCD panel arrays are set on one piece of glass substrate 1, in two pieces of glass substrates 1
Frame glue 2 is coated with positioned at the periphery of every group of sub- LCD panel array, the frame glue 2 is included along the son of glass substrate 1
The first sub- frame glue 3 and be coated on glass substrate 1 positioned at sub- liquid crystal that four outer side edges of LCD panel array are coated with
