Description
Technical Field
The application relates to the field of display technology manufacturing, in particular to a polarizer attaching method.
Background
With the continuous development of TFT-LCD (Thin Film Transistor-liquid Crystal Display) technology, ultra-Thin, ultra-light, and frameless products are becoming more and more widespread and gradually becoming a trend. At present, the thin competition of the whole machine is more and more intense, each whole machine manufacturer carries out the thin design of the product by various modes such as reducing the number of layers of backlight source membranes, reducing the thickness of a light guide plate, thinning the thickness of double-sided adhesive tape and the like, the thinnest television can be 4mm or even thinner, so that each manufacturer is necessary to be able to weigh down even the thickness of dozens of micrometers.
The thickness of each film layer of the polarizer can be directly reduced in order to achieve a simple and thin design, the requirement on a stretching process is high, the stretching speed and the like have high requirements, the equipment cost is improved, the capacity is reduced, and the problems of breakage, indentation, tail end wave warping, difficulty in maintenance and the like are easily caused in the attaching process. In another method, a double-sided supporting layer is changed into a single-sided supporting layer, so that the thickness of the polarizer can be effectively reduced; in terms of material cost, the supporting layer accounts for 54% of the polarizer, and the single-layer supporting layer can also greatly reduce the cost, so more and more polarizer manufacturers start the development of single-support-layer products.
The polaroid of the double-sided support layer is prepared by soaking iodine or dye on the surface of a PVA layer, then carrying out a uniaxial stretching orientation process, and finally attaching the double-sided support layer. Since the PVA layer is very sensitive to moisture and shrinks in the orientation direction (i.e., the absorption axis direction of the polarized light molecules) after dehydration, the supporting layer functions to block moisture and fix the orientation force in addition to protecting the PVA layer and increasing the material strength. The display panel manufactured by the polaroid of the double-sided support layer has different warping modes when the attaching forms of the polaroids are different due to different absorption axes of the 0-degree polaroids and the 90-degree polaroids. When the 0-degree polaroid is attached to one side of the color film substrate of the display panel, the absorption axis of the polaroid is parallel to the long edge of the display panel, and the display panel shows long-edge bowl warping and saddle-type warping of short-edge tortoise warping. As shown in fig. 1, the long side of the upper polarizer 11 'of the display panel 10' is retracted inward to form a bowl-warped shape a on the long side, the short side of the lower polarizer 12 'of the display panel 10' is retracted inward to form a tortoise-warped shape B on the short side, and the display panel 10 is warped in a saddle shape under the influence of the retraction stress.
The support layer mainly has the functions of protecting the PVA layer, increasing the strength of the material, blocking water vapor and fixing the orientation force; therefore, the polarizer of the single supporting layer has unbalanced shrinkage force in the middle layer, the PVA layer on the side without the supporting layer is easier to dehydrate and shrink, the material is softer than the conventional polarizer, and larger warpage is easier to generate. As shown in fig. 2(a) and 2(b), the warpage of the display panel with the polarizer attached to the single support layer after 20 days (20D) is significantly higher than that of the display panel with the polarizer attached to the double support layer after 20 days, that is, experiments show that the sample made of the polarizer of the single support layer has a higher warpage ratio and a greater degree after being placed for the same time. The method comprises the following steps of (1) evaluating the warpage of a long side by fixing one side and the middle position of a short side of a display panel and testing the other side of the short side of the display panel; and testing the warping degree of the short edge by adopting a red rope testing method, and marking the maximum value of the gap between the red rope and the display panel as the warping value of the short edge. In the tables of fig. 2(a) and 2(b), "GL side" and "GR side" mean that the GL side (left side) or the GR side (right side) is tested after the display panel is placed with the face of the Chip On Film (COF) facing downward during the test.
Due to the demand of thinning of the liquid crystal display panel, the backlight source is thinner and thinner, and the market share of the side-entry product is higher and higher; however, when the size of the display panel is continuously increased, the thinned backlight module has the defects that the overall backlight strength is insufficient, and warping occurs in the carrying process, and investigation shows that the backlight source of the large-size display panel is generally in a long-edge bowl warping shape, the warping degree is large, the warping degree of the short edge is generally good, and particularly the display panel without a frame; the frameless display panel has strict quality requirements, is a high-end product, is also a big bright point due to ultrathin and ultralight, and has especially low backboard strength; the frameless display panel is fixed on the middle frame through the double faced adhesive tape, the display panel has stress and cannot be released, and meanwhile, the display panel is not shielded by the front frame, so that light leakage of the whole machine is high, but the quality requirement is very strict. Experiments show that when the display panel of the tortoise perk is attached to the backlight module of the bowl perk, the light leakage can be caused due to the existence of the space gap, the larger the warping difference value is, the more serious the light leakage degree is, and experiments prove that the light leakage degree of the whole machine assembled by the display panel of the tortoise perk is obviously heavier than that of the whole machine assembled by the display panel of the bowl perk.
Therefore, how to effectively produce a display panel warped toward one side of the color film substrate is a difficult problem to be solved in the field.

The embodiment provides a polarizer attaching method. The polarizer attaching method is used for attaching a polarizer to the display panel 10 to be attached. The display panel 10 to be attached includes a color film substrate 11 and an array substrate 12 which are stacked.
Please refer to fig. 3, in which the polarizer attaching method includes the following steps:
step 100: providing a polarizer attaching device, the polarizer attaching device comprising: the attaching guide roller set comprises two guide rollers which are oppositely arranged up and down, and the initial gap between the two guide rollers is equal to the sum of the thickness of the display panel to be attached and the thickness of the polaroid;
step 200: adjusting the position of a guide roller positioned on one side of a color film substrate according to the position of the color film substrate in the display panel to be attached, so that the guide roller positioned on one side of the color film substrate is close to a distance D to a center line of the initial gap in the vertical direction, and the display panel attached with the polarizer generates bowl warping on one surface of the color film substrate;
step 300: and the attaching guide roller group attaches the polaroid to the display panel to be attached.
According to the polaroid attaching method, the position of the guide roller positioned on one side of the color film substrate is adjusted, so that when the polaroid is attached, an acting force is applied to one surface of the color film substrate in the display panel to be attached through the adjusted guide roller to enable the display panel to generate bowl tilting to one side of the color film substrate, and the probability of light leakage generated on the periphery of the whole assembled display panel is effectively reduced.
In this embodiment, the polarizer attaching method is applied to two different situations:
in one case, the first polarizer on one side of the color film substrate and the second polarizer on one side of the array substrate are attached at the same time. In this case, the position of the guide roller located on one side of the color film substrate is adjusted according to the position of the color film substrate in the display panel to be attached, so that the guide roller located on one side of the color film substrate is close to a distance D to a center line of the initial gap in the vertical direction, and the display panel to which the polarizer is attached is enabled to generate bowl tilting on one surface of the color film substrate. Specifically, the distance D is 0.5mm to 2.0 mm.
In another case, the first polarizer 31 on the side of the array substrate 12 is attached first, and then the second polarizer 32 on the side of the color filter substrate 11 is attached, in which case, the steps 200 and 300 are performed once when the first polarizer 31 on the side of the array substrate 12 is attached, and then performed once again when the second polarizer 32 on the side of the color filter substrate 11 is attached.
Specifically, in step 100, the two guide rollers of the attached guide roller set are a first guide roller 21 and a second guide roller 22, respectively, the first guide roller 21 is located above the second guide roller 22, and the polarizer to be attached is located below the display panel 10 to be attached.
In steps 200 and 300, the attaching method includes:
as shown in fig. 4(a), the position of the first guide roller 21 is adjusted so that the first guide roller 21 approaches the center line C in the vertical direction of the initial gap by a first distance D1;
as shown in fig. 4(b), a first polarizer 31 is attached to one surface of the array substrate 12 of the display panel 10 to be attached;
turning the display panel 10 to be attached up and down, and resetting the adjusted first guide roller 21;
as shown in fig. 4(C), the position of the second guide roller 22 is adjusted so that the center line C of the second guide roller 22 in the vertical direction of the initial gap is close to the second distance D2;
as shown in fig. 4(d), a second polarizer 32 is attached to one surface of the color filter substrate 11 of the display panel 10 to be attached.
In the above steps, when the first polarizer 31 is attached to one surface of the array substrate 12 of the display panel 10 to be attached, a first tension is applied to the first polarizer 31; applying a second tension to the second polarizer 32 when the second polarizer 32 is attached to one surface of the color film substrate 11 of the display panel 10 to be attached; wherein the first tension is less than the second tension. The first tension and the second tension are both applied by the second guide roller 22 positioned on one side of the polarizer to be attached, and the adsorption force of the second guide roller 22 can be adjusted by adjusting the cylinder on the second guide roller 22, so that the tension on the polarizer is generated. Specifically, the magnitude of the adsorption force of the second guide roller 22 can be adjusted by an electrically controlled solenoid valve of a cylinder on the cylinder, or the magnitude of the adsorption force of the second guide roller 22 can be manually adjusted. Tension adjustment is the increase or reduces the power of dragging the polaroid, because the polaroid is elastic, the polaroid is taut under second tension (higher tension) effect, after the attachement is accomplished like this, the polaroid can reply, because the tension difference that the polaroid on two sides received will have the uneven phenomenon of power, display panel is dragged to the big direction of pulling force to the display panel that attaches out at last, glass takes place the warpage, thereby reach the display panel that produces to the perk of a colored film base plate side bowl, and still keep the bowl to stick up the form after long-term chronogenesis change, it is bad to effectively reduce peripheral light leak.
Specifically, the first distance D1 is equal to the second distance D2, or the first distance D1 is not equal to the second distance D2. The first distance D1 is 0.5 mm-2.0 mm; the second distance D2 is 0.5 mm-2.0 mm. If the first distance D1 is 0.5mm and the second distance D2 is 1.0mm, the adjustment is made according to actual requirements.
In other embodiments, a polarizer may be attached to one surface of a color film substrate of the display panel to be attached first; then, turning over the display panel to be attached up and down, and resetting the adjusted guide roller; and finally, attaching a polaroid to one surface of the array substrate in the display panel to be attached.
Both of the above-mentioned attaching sequences are possible. In actual production, one surface of the color film substrate in the display panel to be attached directly faces a user, and the attachment requirement is generally high, so that the color film substrate is generally placed at the last attachment to facilitate operations such as related monitoring.
Preferably, in attaching the first polarizer 31 to one surface of the array substrate 12 of the display panel 10 to be attached, the attaching direction of the display panel 10 to be attached is the width direction of the display panel 10 to be attached; in attaching the second polarizer 32 to one surface of the color filter substrate 11 of the display panel 10 to be attached, the attaching direction of the display panel 10 to be attached is the long side direction of the display panel 10 to be attached. And the long edge force application ensures that the long edge bowl of the display panel warps, and the short edge force application ensures that the short edge bowl of the display panel warps.
Preferably, the effect of the bowl tilting can be enhanced by matching with the change of the fitting speed, the fitting speed is low, the stress time of the display panel is long, and the bowl tilting is more obvious. Specifically, the polarizer is attached to the display panel 10 to be attached in the attaching guide roller set at an attaching speed of 50mm/s to 80 mm/s.
The polaroid comprises a polarizing film, a protective film arranged on one side of the polarizing film and a release film arranged on the other side of the polarizing film. When the attaching guide roller set attaches the polarizer to the display panel 10 to be attached, the polarizer attaching method includes: the release film 32 is peeled off from the polarizing film by a separation guide roller 40. Specifically, the incoming material of the polarizer is a roll, and the roll-shaped polarizer is peeled off from the polarizing film by the release film 32 through the separation guide roller 40 while being attached to the display panel 10. But not limited thereto, when the material coming from the polarizer is a sheet, the polarizer may be attached to the display panel 10 to be attached after the release film of the positive polarizer is completely removed.
The display panel attached by the polarizer attaching method provided by the embodiment adopts a method of fixing one side of the short edge of the display panel and the middle position and testing the other side of the short edge of the display panel to evaluate the warpage of the long edge, and specific experimental data are shown in a secular warpage change table of the display panel of fig. 5. As can be seen from the table, experiments prove that the long edge of the display panel can still keep the bowl-warped shape after 34 days (34D) and the light leakage proportion is 0.003 percent after the display panel is attached to the backlight module, thereby effectively reducing the probability of light leakage generated at the periphery of the whole assembled display panel.
The polarizer attaching method provided by the embodiment can not only effectively reduce the light leakage probability of the whole assembled display panel using the polarizer with the single support layer in the background art, but also effectively reduce the light leakage probability of the whole assembled display panel using the polarizer with the double support layers.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
