Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
Present embodiment provides a kind of curved surface manufacture craft of IPS screens, as shown in figure 1, comprising the following steps：
S10, the IPS screens 200 assembled are placed on curved surface tool 100 (as shown in Figure 2)；
Specifically, IPS screens 200 from top to bottom include upper polaroid 201, upper glass 202, liquid crystal 203, lower glass successively
204 and down polaroid 205, the down polaroid 205 of the IPS screens 200 assembled is fitted with curved surface tool 100.Above-mentioned curved surface
Tool 100 can be made up of a variety of high temperature resistant materials such as PC, PMMA, bakelite.IPS screens 200 are by adjusting the song of curved surface tool 100
Rate prepares the IPS screens 200 of different curvature.
S20, the above-mentioned IPS screens 200 being placed on curved surface tool 100 are heated and are incubated, heating-up temperature is 50 DEG C -90
DEG C, soaking time 24h-120h；So that IPS screens 200 form the Curved screen of natural torsion, the uniformly bending point of liquid crystal molecule 213
Cloth (as shown in Figure 3), curved face product are assembled without pressure point, avoided because of light leak caused by compressing.When above-mentioned heating-up temperature and insulation
Between cause IPS screens 200 keep with the identical degree of crook of curved surface tool 100, be unlikely to when being removed from curved surface tool 100 return
Former state is arrived again.When heating-up temperature is less than 50 DEG C, it is insufficient to allow upper polaroid 201 and down polaroid 205 to expand and produce
Deformation；When heating-up temperature is higher than 90 DEG C, heating cost is high, inconvenient for operation.Soaking time is less than 24h so that IPS screens 200
Without legal type；When soaking time is higher more than in 120h, production cost.For example, heating-up temperature can be 50 DEG C, 60 DEG C, 70 DEG C,
80 DEG C, 90 DEG C etc., soaking time can be 24h, 48h, 72h, 96h, 120h etc., and heating-up temperature and soaking time can also bases
Specific demand is adjusted.Preferably, the heating-up temperature for the IPS screens 200 being placed in the present embodiment on curved surface tool 100 is 60
DEG C, soaking time 72h.Above-mentioned heating process can be carried out in any equipment that can provide high-temperature heating.Heating process can
Check that 200 some other normal temperature of IPS screens are difficult to find bad, such as：Mura is bad, and IC is bad, DOT points etc..
S30, by above-mentioned heating and be incubated after IPS screens 200 stand at normal temperatures.Specifically, by after heating and insulation
IPS screens 200 stand 24h-120h at normal temperatures, for example, normal temperature time of repose can be 24h, 48h, 72h, 96h, 120h etc..It is excellent
Choosing, the IPS screens 200 after heating and insulation are placed under normal temperature and stand 72h.
The curved surface manufacture craft of above-mentioned IPS screens 200, IPS screens 200 are placed on curved surface tool 100, through high-temperature heating and often
Temperature, which stands the upper polaroid 201 of the IPS screens 200 after cooling and down polaroid 205, to be expanded and bend accordingly, liquid crystal molecule
213 uniformly bending distributions, IPS screens 200 are kept and bending tool identical degree of crook, avoid physics compressing during assembling,
The generation of light leakage phenomena can effectively be avoided.The curved surface manufacture craft of above-mentioned IPS screens 200 is applied to IPS Curved screens and other are any
Electric field is transverse electric field, the horizontally arranged liquid crystal display of liquid crystal molecule 213.
Present embodiment also provides a kind of IPS screens 200, is prepared using the curved surface manufacture craft of above-mentioned IPS screens 200.Should
Curved surface IPS screens 200 avoid the physics compressing from backlight module, can effectively avoid the phenomenon of light leak from occurring.
Present embodiment also provides a kind of display device, including above-mentioned IPS screens 200.The display device effectively avoids leak
The phenomenon of light occurs, and the experience effect of user is more preferably.
Pay attention to, above are only presently preferred embodiments of the present invention.It will be appreciated by those skilled in the art that the invention is not restricted to here
Described specific embodiment, can carry out for a person skilled in the art it is various significantly change, readjust and substitute and
Without departing from the scope of protection of the present invention.Therefore, although being described in further detail by above example to the present invention,
But the present invention is not limited only to above example, without departing from the inventive concept, can also include it is more other
