Description
Technical Field
The present invention relates to a display device, and more particularly, to a liquid crystal panel.
Background
With the development of display technology, all devices are becoming smaller, thinner and lighter, and thus the mainstream display devices in the market are being developed from conventional cathode ray tubes to liquid crystal display devices. In particular, liquid crystal display devices are used in a wide variety of fields, and display devices such as mobile phones, notebook computers, video cameras, music players, mobile navigation devices, and televisions, which are used in daily life, are mostly provided with liquid crystal panels.
In a conventional liquid crystal panel, a liquid crystal cell is disposed between two polarizers. However, some liquid crystal panels with special functions only have a single polarizer, and are prone to warp due to inconsistent stress on both sides of the liquid crystal cell during the manufacturing process. In addition, the liquid crystal glass is directly exposed on the side of the liquid crystal cell without the polarizer, which is also prone to cause surface scratch or pollution.
In the known solution, a polyethylene terephthalate (PET) protective sheet is disposed on one side of the liquid crystal cell without the polarizer, but due to the characteristics of the material, interference, commonly called rainbow-pattern phenomenon, is easily generated when light passes through the protective sheet, which is not favorable for the picture inspection in the manufacturing process.
The background section is provided to facilitate an understanding of the present disclosure, and thus the disclosure in the background section may include other art that is not known to those of skill in the art. Furthermore, the statements contained in the "background" section do not represent a representation of the claimed subject matter or the problems associated with one or more embodiments of the present disclosure, nor are they intended to be known or appreciated by those skilled in the art prior to the present disclosure.
Disclosure of Invention
The invention provides a liquid crystal panel which can reduce warping phenomenon, surface scratch and pollution and is easy to carry out picture inspection.
Other objects and advantages of the present invention will be further understood from the technical features disclosed in the present invention.
In order to achieve one or a part of or all of the above or other objects, an embodiment of the invention provides a liquid crystal panel including a liquid crystal cell, a polarizer and a low-retardation protection sheet. The polaroid is arranged on one side of the liquid crystal box and is provided with a penetrating shaft. The protective sheet with low phase difference is arranged on one side of the liquid crystal box far away from the polaroid.
In the liquid crystal panel of the embodiment of the invention, the protection sheet is arranged on one side of the liquid crystal box far away from the polarizer, so that the warping phenomenon of the liquid crystal box can be reduced, and the scratch or pollution on the surface of the liquid crystal box can be reduced. In addition, compared with the polyethylene terephthalate (PET) protective sheet used in the prior art, the low-phase difference protective sheet used in the embodiment of the present invention can reduce interference generated when light passes through, namely, a so-called rainbow effect phenomenon, so that the liquid crystal panel in the embodiment of the present invention can be easily inspected on a picture during the manufacturing process.
In order to make the aforementioned and other objects, features and advantages of the present invention comprehensible, preferred embodiments accompanied with figures are described in detail below.

Detailed Description
The foregoing and other aspects, features and advantages of the invention will be apparent from the following more particular description of preferred embodiments of the invention, as illustrated in the accompanying drawings. Directional terms as referred to in the following examples, for example: up, down, left, right, front or rear, etc., are simply directions with reference to the drawings. Accordingly, the directional terminology is used for purposes of illustration and is in no way limiting.
Fig. 1 is a schematic perspective view of a liquid crystal panel according to an embodiment of the invention. Fig. 2 is a schematic cross-sectional view of a liquid crystal panel according to an embodiment of the invention. Referring to fig. 1 and 2, a liquid crystal panel 10 of the present embodiment includes a liquid crystal cell 100, a polarizer 200, and a protective sheet 300 with a low retardation. The polarizer 200 is disposed at one side of the liquid crystal cell 100 and has a transmission axis (not shown). The transmission axis is adapted to pass light rays of a polarization direction parallel to the transmission axis. The protective sheet 300 with low retardation is disposed on the side of the liquid crystal cell 100 away from the polarizer 200. In other words, the polarizer 200 and the low retardation protection sheet 300 are respectively located at two opposite sides of the liquid crystal cell 100. The polarizer 200 and the protective sheet 300 having a low retardation are, for example, disposed symmetrically on opposite sides of the liquid crystal cell 100, but are not limited thereto. With the above configuration, the stress applied to the liquid crystal cell 100 of the present embodiment on the side where the polarizer 200 is disposed is substantially the same as the stress applied to the liquid crystal cell 100 on the side where the protective sheet 300 with a low retardation is disposed, so that the liquid crystal panel 10 of the present embodiment can reduce the warping phenomenon caused by the stress unevenness compared to a liquid crystal panel without the protective sheet 300 with a low retardation.
In the present embodiment, the protective sheet 300 of low phase difference is adapted to provide a protective function. Specifically, the protective sheet 300 with a low retardation is, for example, but not limited to, completely covering the liquid crystal cell 100. The angle relationship in fig. 1 does not allow complete representation. For the protection function, the area of the protective sheet 300 of low phase difference is, for example, equal to or larger than the area of the side of the liquid crystal cell 100 facing the protective sheet 300 of low phase difference. The thickness of the protective sheet 300 having a low phase difference is, for example, 0.08mm to 0.16 mm.
In order to solve the rainbow effect generated when using a general PET protective sheet in the prior art, the protective sheet 300 having a low phase difference is used in the embodiment of the present invention. When polarized light of the liquid crystal panel penetrates through the plastic protection sheet, the polarized light can be divided into a faster path and a slower path in the plastic protection sheet, and the relative distance of the speed difference between the two paths is the phase difference. A general PET protective sheet has a large refractive index and a high retardation, and thus rainbow unevenness is likely to occur in visual observation. The embodiment of the invention uses the protective sheet 300 with low phase difference, so that the rainbow effect can be reduced, and further the liquid crystal panel 10 of the embodiment of the invention can be easily checked in the manufacturing process.
Specifically, the retardation of the low-retardation protective sheet 300 of the present embodiment is, for example, less than 15 nm. Since the retardation has a positive correlation with the refractive index, the low-retardation protective sheet 300 of the present embodiment uses a low-refractive index material (for example, a refractive index lower than 1.5), such as polymethyl methacrylate (PMMA), Triacetylcellulose (TAC), or Polycarbonate (PC). Alternatively, composite polyethylene terephthalate, which is a material having a refractive index higher than 1.5, may be used, but the phase difference may be adjusted to less than 15 nm. The protective sheet 300 for low phase difference according to the embodiment of the present invention is not limited to the above-described examples as long as the same low phase difference effect can be achieved.
In the present embodiment, the protective sheet 300 having a low phase difference has, for example, a peelable property, but is not limited thereto. Fig. 3 is a schematic view of a protective sheet with low phase difference according to an embodiment of the invention. Referring to fig. 1 and 3, before being disposed on the liquid crystal panel 10, the low-phase-difference protection sheet 300a of the present embodiment includes, for example, a low-phase-difference film 310, a pressure-sensitive adhesive 320, and a release film 330. The pressure-sensitive adhesive 320 is disposed between the low retardation film 310 and the release film 330. The pressure-sensitive adhesive 320 and the release film 330 are all known in the art, and the material of the low retardation film 310 is as described above. When the protective sheet 300a with a low retardation is disposed on the liquid crystal panel 10, the pressure-sensitive adhesive 320 is separated from the release film 330, the low retardation film 310 and the pressure-sensitive adhesive 320 are disposed on one side of the liquid crystal cell 100, and the pressure-sensitive adhesive 320 is disposed between the low retardation film 310 and the liquid crystal cell 100 (not shown), thereby forming the protective sheet 300 with a low retardation. Therefore, the protective sheet 300 with low phase difference of the present embodiment has a peelable property, and depending on the type of the pressure sensitive adhesive 320, the protective sheet 300 with low phase difference can be peeled off from the liquid crystal cell 100 again, for example, to perform the subsequent assembly process of the liquid crystal panel 10. The following will further describe embodiments of the liquid crystal cell 100 with reference to the drawings, but the specific architecture of the liquid crystal cell of the present invention is not limited to the embodiments listed below.
FIG. 4 is a schematic diagram of a liquid crystal cell according to an embodiment of the invention. Referring to fig. 1 and 4, a liquid crystal cell 100 of the present embodiment includes, for example, an upper substrate 110, a lower substrate 120, an upper electrode layer 130, a lower electrode layer 140, an upper alignment layer 150, a lower alignment layer 160, and a liquid crystal layer 170. The upper substrate 110 is disposed opposite to the lower substrate 120. The upper electrode layer 130 is disposed on a side of the upper substrate 110 facing the lower substrate 120, and the lower electrode layer 140 is disposed on a side of the lower substrate 120 facing the upper substrate 110. The liquid crystal layer 170 is disposed between the upper substrate 110 and the lower substrate 120 and has a plurality of liquid crystal molecules 171. The upper alignment layer 150 is disposed on a side of the upper substrate 110 facing the lower substrate 120, the lower alignment layer 160 is disposed on a side of the lower substrate 120 facing the upper substrate 110, and the liquid crystal layer 170 is further disposed between the upper alignment layer 150 and the lower alignment layer 160, wherein the upper alignment layer 150 is for aligning liquid crystal molecules 171 adjacent to the upper substrate 110, and the lower alignment layer 160 is for aligning liquid crystal molecules 171 adjacent to the lower substrate 120. The upper alignment layer 150 and the lower alignment layer 160 have alignment directions (not shown), respectively, and the transmission axis of the polarizer 200 is substantially parallel or perpendicular to the alignment directions of the upper alignment layer 150 and the lower alignment layer 160, for example, but not limited thereto.
The upper substrate 110 and the lower substrate 120 can be made of a substrate material commonly used in the art, such as glass, plastic, flexible material, etc. The upper electrode layer 130 and the lower electrode layer 140 can be made of transparent conductive electrode materials (such as ITO, IZO or ITZO) commonly used in the art. The upper alignment layer 150 and the lower alignment layer 160 can be made of, for example, an alignment layer material commonly used in the art, such as Polyimide (PI), and can be aligned by a rubbing alignment process or a photo-alignment process. Examples of the liquid crystal layer 170 include, for example, Vertical Alignment (VA), Twisted Nematic (TN), Super Twisted Nematic (STN), or in-plane switching (IPS) type liquid crystals. The liquid crystal layer 170 may be used to transmit or block light from the light source via a voltage supplied from the driving circuit.
In the embodiment, the low-retardation protection sheet 300 (the low-retardation film 310 and the pressure-sensitive adhesive 320) is directly attached to and in contact with the surface of the upper substrate 110 away from the liquid crystal layer 170, and the polarizer 200 is directly attached to and in contact with the surface of the lower substrate 120 away from the liquid crystal layer 170. In other words, no other optical film exists between the protective sheet 300 with low retardation and the upper substrate 110, and similarly, no other optical film exists between the polarizer 200 and the lower substrate 120.
In summary, in the liquid crystal panel according to the embodiment of the invention, the protection sheet is disposed on the side of the liquid crystal cell away from the polarizer, so that the stress applied to the liquid crystal cell can be balanced, the warping phenomenon of the liquid crystal cell can be reduced, and the scratching or contamination caused by the exposure of the surface of the liquid crystal cell can be reduced due to the disposition of the protection sheet. In addition, compared with the polyethylene terephthalate protective sheet used in the prior art, the embodiment of the invention uses the protective sheet with low phase difference, so that the interference generated when light passes through, namely the phenomenon known as rainbow texture, can be reduced, and the liquid crystal panel of the embodiment of the invention is easy to inspect pictures in the manufacturing process.
However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made by the claims and the summary of the invention are still within the scope of the present invention. Moreover, it is not necessary for any embodiment or claim of the invention to address all of the objects, advantages, or features disclosed herein.
