Background
Due to the flexibility of the flexible display device, high requirements are placed on the bending resistance of the film materials forming the flexible display screen.

The terms "first," "second," and the like in the description and in the claims, and in the drawings, are used for distinguishing between different objects and not necessarily for describing a particular sequential order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Referring to fig. 1 and fig. 2, a polarizing structure 10 according to a first embodiment of the present invention includes a polarizer 100, a retardation film 200, and a first protective layer 300, wherein an absorption axis direction a of the polarizer 100 and a stretching direction B of the polarizing structure 10 have a predetermined angle α (as shown in fig. 2), the predetermined angle α is greater than or equal to 0 °, and the predetermined angle α is smaller than 45 °; the phase difference film 200 is disposed at one side of the polarizer 100; the first protective layer 300 is disposed on a side of the polarizer 100 away from the retardation film 200 for protecting the polarizer 100.
In the present application, the retardation film 200 is used to change the phase of incident light, or change the polarization direction of incident light, or the retardation film 200 is used to convert incident light from linearly polarized light to circularly polarized light or elliptically polarized light, or convert circularly polarized light or elliptically polarized light to linearly polarized light; polarizer 100 is used to absorb light perpendicular to the absorption axis of polarizer 100.
In some embodiments, when the polarization structure 10 is applied to the display panel 10, for example, in an organic electroluminescent display panel, since the organic electroluminescent display panel is self-luminous, when external light is incident to a cathode in the display panel, the external light is reflected by the cathode onto the display panel, thereby affecting the viewing effect and the display contrast. After the polarization structure 10 of the present application is disposed in the display panel 10, when the external light is incident into the polarization structure 10 from the surface of the first protection layer 300 away from the polarizer 100, the polarizer 100 is used to absorb the external light parallel to the absorption axis, so that the light perpendicular to the absorption axis of the polarizer 100 is transmitted, and then the light transmitted through the polarizer 100 is reflected on the cathode and then passes through the retardation film 200 to adjust the phase, for example, the light is deflected by 90 °, so that the light reflected by the cathode cannot pass through the polarizer 100, and the problem of reflection of the external light can be solved.
The above-described embodiments are directed to the use of the polarizing structure 10 of the present application for adjusting the external light incident from the side of the polarizer 100 away from the retardation film 200. In other embodiments, the polarizing structure 10 of the present application may also be used to modulate other light incident from the side of the retardation film 200 away from the polarizer 100. That is, in the present application, the retardation film 200 and the polarizer 100 are used in combination for adjusting incident light on either side, which is not limited to external light or electroluminescence light.
Referring to FIG. 3, when the absorption axis direction A of the polarizer 100 is perpendicular to the stretching direction B of the polarizing structure 10, cracks are generated in the polarizer 100 substantially parallel to the absorption axis direction A when the polarizing structure 10 is stretched. In the present invention, the preset included angle α between the absorption axis direction of the polarizer 00 and the stretching direction of the polarizing structure 10 is set as: the preset angle α is greater than or equal to 0 ° and smaller than 45 °, which can reduce the risk of cracks generated in the polarizer 100 when the polarizing structure 10 is stretched, or can reduce cracks generated in the polarizer 100 when the polarizing structure 10 is stretched. Preferably, the preset angle α is greater than or equal to 0 °, and the preset angle α is less than or equal to 15 °. More preferably, when the absorption axis direction a of the polarizer 100 is parallel to the stretching direction B of the polarizing structure 10, i.e., the predetermined angle α is equal to 0 °, no cracks are generated in the absorption axis direction a of the polarizer 100, and the effect is optimal.
In order to illustrate the superiority of the above-mentioned numerical setting of the preset angle α, the present invention also provides a comparative example in which the preset angle α is set equal to 45 ° and the preset angle is greater than 45 °, and it is found that the cracks generated when the polarizing structure 10 is stretched are significantly greater than those generated in the example of the present invention, because when the preset angle is too large, the component force of the polarizing structure 10 in the stretching direction perpendicular to the absorption axis direction a is greater, and the greater component force tears the polarizer 100 to generate more cracks when the polarizing structure 10 is stretched.
It should be noted that, in the present application, the predetermined angle refers to an included angle between the absorption axis direction a and the stretching direction B of the polarizing structure 10, that is, the predetermined angle refers to an included angle smaller than 90 °.
In this embodiment, if the angles of the slow axis direction and the bending direction of the entire retardation film 200 are changed when the absorption axis direction of the polarizer 100 is adjusted, the slow axis direction of the retardation film 200 can be adjusted by reducing the reflectance and the reflection hue of the retardation film 200 corresponding to the bent portion of the polarizing structure 10, so as to obtain the polarizing structure 10 excellent in the bending resistance as a whole.
According to the polarizing structure 10 provided by the invention, the absorption axis direction of the polarizer 100 and the stretching direction of the polarizing structure 10 are arranged to form the preset angle alpha, the preset angle alpha is greater than or equal to 0 degrees, and the preset angle alpha is smaller than 45 degrees, so that cracks of the polarizer 100 can be reduced when the polarizing structure 10 is stretched.
In a further embodiment, the first protective layer 300 includes at least one of polymethylmethacrylate, a triacetate fiber film, or a cyclic olefin polymer; the polarizer 100 is a polyvinyl alcohol polarizer.
Referring to fig. 1 again, in a further embodiment, the polarizing structure 10 further includes a first adhesive layer 400 and a second adhesive layer 500, the first adhesive layer 400 is disposed on a side of the polarizer 100 away from the first protective layer 300; the retardation film 200 includes a quarter-wave plate 210, the quarter-wave plate 210 is disposed on a side of the first adhesive layer 400 away from the polarizer 100; the second adhesive layer 500 is disposed on a side of the quarter-wave plate 210 away from the polarizer 100. Wherein the quarter-wave plate 210 is used for changing linearly polarized light into circularly polarized light or elliptically polarized light; or to change circularly polarized light or elliptically polarized light into linearly polarized light. In the present embodiment, the incident light is modulated by the polarizer 100 and the quarter-wave plate 210 in combination. The second adhesive layer 500 is used to adhere to a target device to bond the polarizing structure 10 to the target device.
Referring to fig. 4, a second embodiment of the invention provides a polarizing structure 10a, which is different from the first embodiment in that the polarizing structure 10a further includes a third adhesive layer 600, and the third adhesive layer 600 is disposed on a side of the polarizer 100 away from the first protective layer 300; the retardation film 200 further includes a half-wave plate 220, wherein the half-wave plate 220 is disposed on a side of the third adhesive layer 600 away from the polarizer 100; the first glue layer 400 is disposed on a side of the half-wave plate 220 away from the third glue layer 600. In the present embodiment, the incident light is adjusted by the combination of the polarizer 100, the quarter wave plate 210 and the half wave plate 220.
Referring to fig. 5, a polarization structure 10b according to a third embodiment of the present invention is different from the second embodiment in that the polarization structure 10b further includes a second protection layer 700, and the second protection layer 700 is disposed on a side of the polarizer 100 away from the first protection layer 300; the third adhesive layer 600 is disposed on a side of the second protective layer 700 away from the polarizer 100. In this embodiment, the first protective layer 300 and the second protective layer 700 both use cellulose triacetate films, and a double-layer protective film is used to protect the polarizing structure 10 b.
Referring to fig. 6, a polarization structure 10c according to a fourth embodiment of the present invention is different from the third embodiment in that the polarization structure 10c further includes a third protection layer 800, the third protection layer 800 is disposed on a side of the first protection layer 300 away from the polarizer 100, and a hardness of the third protection layer 800 is greater than a hardness of the first protection layer 300. The third protective layer 800 having a greater hardness may protect the polarizing structure 10c from external abrasion.
Wherein the third protection layer 800 may also be disposed as in the first and second embodiments for protecting the polarization structure 10c from external abrasion.
In any of the first to fourth embodiments, the bending radius of the polarizing structure 10 when bent is 1.14 mm or more.
