Abstract
The invention discloses a kind of high-flatness liquid crystal display structure production methods, in the technique of segmentation glass, control subdivided gap；And/or the density of control frame partial size and wadding in the partial size difference and liquid crystal region of gasket material in liquid crystal region.The present invention reduces the formation of Newton's ring to realize the production of high-flatness liquid crystal display from the technique of segmentation glass and to the control of wadding setting specification.
Description
Technical field
The present invention relates to display glass technology field, especially a kind of high-flatness liquid crystal display structure production methods.
Background technique
Because the primary structure of LCD is that two panels ito glass keeps certain gap, it is full of between the gap of two sheet glass
Liquid crystal.The distance between two sheet glass cannot be guaranteed substantially uniformity in the actual production process, and be typically all intermediate ratio
Trend that is higher, being gradually decreased toward surrounding.Because there is the presence of difference in height, surface reflection of the light in upper and lower two sheet glass
Light can generate optical path difference, when optical path difference be equal to 1/2 wavelength integral multiple when (about 300nm), light and dark newton can be generated
Ring.
Because general LCD production commercial city is put into production with big sheet glass, the finished product of granule is cut in rear process.
And in order to reduce cost, granule distance is generally all accomplished minimum as far as possible by raising glass utilization, most to reach typesetting quantity
Purpose.But one of the reason of test discovery, such way formally leads to Newton's ring, because LCD has 180 degree in bonding process
High-temperature baking and there is certain pressure, and silk-screen glue firmly sticks together upper and lower two sheet glass, then glass is again cold
But room temperature is arrived, so generating stress during glass expands with heat and contract with cold, causes the gap of upper and lower two sheet glass uneven.
As shown in Figure 1, because the wadding 4a of wadding 3a and centre in frame silk-screen glue can be deformed when being pressurized,
But after the completion of to version process, after pressure removes, intermediate wadding can rebound, and slightly have the gap between two sheet glass 1a
Increase；But the wadding in frame silk-screen glue is without rebound, because the silk-screen glue of frame has been cured, two sheet glass are secured
Stick together, although the wadding in frame silk-screen glue has the tendency that rebound, but the power to rebound is far from silk-screen glue
The adhesive force of 2a is big, so can't actually change the gap between two sheet glass.Due to above, intermediate wadding is anti-
The wadding of bullet, frame silk-screen glue does not rebound, so causing intermediate gap big, the gap by edge is small, in turn results in newton
Ring is bad.
Summary of the invention
The technical problem to be solved by the present invention is in view of the above shortcomings of the prior art, provide a kind of high-flatness liquid crystal
Show construction manufacturing method.
In order to solve the above technical problems, the technical solution used in the present invention is: a kind of high-flatness liquid crystal display structure
Production method, in the technique of segmentation glass, control subdivided gap is 1-6mm；And/or control frame gasket material partial size with
The partial size difference of gasket material in liquid crystal region, keeps frame gasket material partial size big compared with the partial size of gasket material in liquid crystal region
The density of wadding is 30-150/mm in 0.3-0.5 μm and liquid crystal region2。
In above-mentioned technical proposal, the frame gasket material partial size is 3.0-8.0 μm.
The beneficial effects of the present invention are:
1) frame gasket material and the rebound state of gasket material in liquid crystal region are different, influence gap between two sheet glass
Uniformity reduces the density of gasket material in liquid crystal region, makes liquid crystal region by properly increasing the partial size of frame gasket material
Partial size after middle gasket material rebound is suitable with the partial size that frame gasket material deforms.
2) glass internal stress will affect the uniformity in gap between two sheet glass, by increase granule between typesetting away from
From influence of the stress to gap between two sheet glass can be effectively reduced.
Detailed description of the invention
Fig. 1 is the schematic diagram of internal structure that the prior art shows glass；
Fig. 2 is the schematic diagram of subdivided gap of the present invention；
Fig. 3 is the schematic diagram of internal structure the invention shows glass.
In figure, 1, display glass；2, silk-screen glue；3, frame gasket material；4, frame gasket material.
Specific embodiment
The invention will now be described in further detail with reference to the accompanying drawings.
As shown in Fig. 2, a kind of high-flatness liquid crystal display structure production method, divides in the technique of glass, increase big
To the subdivided gap of display glass, subdivided gap 1-6mm on block glass.Such as: flatness is when subdivided gap is 1.2mm
0.2um；Flatness is 0.1um when gap is 5.7mm, compares existing flatness and is generally 0.3 μm or more, have it is bigger into
Step.
As shown in figure 3, improving the partial size of frame gasket material, partial size is 3.0-8.0 μm, and reduces in liquid crystal region and pad
The density of material, the density are 30-150/mm2.Partial size said herein is the partial size to the wadding before version.The present invention
By the partial size difference of gasket material in control frame gasket material and liquid crystal region, gasket material is close in reduction liquid crystal region
Degree keeps the partial size in liquid crystal region after gasket material rebound suitable with the partial size of frame adhesive liner padding, to effectively mitigate ox
Pause ring.General frame wadding partial size is 0.3-0.5 μm big compared with median diameter.
Example 1: frame gasket material partial size 4.0um is served as a contrast in liquid crystal region 4.0 μm of gasket material partial size in liquid crystal region
150/mm of cushion material density2, 0.25 μm of flatness；
Example 2: frame gasket material partial size 4.0um pads material 4.0 μm of gasket material partial size in liquid crystal region in liquid crystal region
Expect 100/mm of density2, 0.18 μm of flatness；
Example 3: frame gasket material partial size 4.2um pads material 4.0 μm of gasket material partial size in liquid crystal region in liquid crystal region
Expect 100/mm of density2, 0.13 μm of flatness；
Example 4: frame gasket material partial size 3.0um pads material 3.0 μm of gasket material partial size in liquid crystal region in liquid crystal region
Expect 150/mm of density2, 0.25 μm of flatness；
Example 5: frame gasket material partial size 3.15um pads material 3.0 μm of gasket material partial size in liquid crystal region in liquid crystal region
Expect 100/mm of density2, 0.11 μm of flatness.
By above example it follows that controlling the partial size difference of gasket material in frame gasket material and liquid crystal region,
And gasket material density can be obviously improved flatness in liquid crystal region.
The above embodiments are merely illustrative and not limiting of the invention, therefore all according to described in present patent application range
The equivalent change or modification done of method, be included in the scope of the patent application of the present invention.
