Patent Application
20160238875
This application claims priority to Chinese Patent Application No. 201510080260.9 filed on Feb. 13, 2015, the contents of which are incorporated by reference herein.
The subject matter herein generally relates to a liquid crystal display structure and a polarizer of the liquid crystal display structure.
A liquid crystal display structure may include a liquid crystal display panel, at least one polarizer, and a backlight assembly.
Implementations of the present technology will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
Several definitions that apply throughout this disclosure will now be presented.
The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other word that “substantially” modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like.
As illustrated in
The liquid crystal display panel 10 can include a first substrate 11, a second substrate 12 opposite to the first substrate 11, and a liquid crystal layer (not shown) located between the first substrate 11 and the second substrate 12. The polarizer 20 can be arranged on a side of the first substrate 11 facing away from the second substrate 12, and the second polarizer 30 can be arranged on a side of the second substrate 12 facing away from the first substrate 11.
The polarizer 20 can include a first section 21 and a second section 22. The first section 21 can be substantially rectangular and be located in a substantially central portion of the polarizer 20. The first section 21 can be aligned with the display area 101. The second section 22 can be substantially rectangular and surround the first section 21. The second section 22 can be aligned with the non-display area 102. The polarizer 20 can define at least one through hole 221 in the second section 22 between every two adjacent corners of the second section 22. In the illustrated embodiment, two through holes 22 are defined between every two adjacent corners of the second section 22. In at least one embodiment, a shortest distance between the through holes 221 and the first section 21 is less than a shortest distance between the through holes 221 and an outer edge of the second section 22. In at least one embodiment, a shape of the through holes 221 is round, but in other embodiments the shape of the through holes 221 can be any shape. In another embodiment, the number of the through holes 221 defined between every two adjacent corners of the second section 22 can be one, three, or a different number, and the number of the through holes 221 defined between different adjacent two corners of the second section 22 can be different. In at least one embodiment, the diameter of the through holes 221 is 2 millimeters, but in other embodiments the diameter can be different.
As illustrated in
In at least one embodiment, the polarizing substrate 203 can be a high-molecular polymer made of a polyvinyl alcohol film colored by an organic dye having dichroism.
In at least one embodiment, the first protecting layer 202 and the second protecting layer 204 can be made of triacetate.
The surface protecting film 201 can protect the polarizer 20 from abrasive or chemical damage and increase a hardness of the polarizer 20.
In at least one embodiment, the adhesive layer 205 can be a pressure-sensitive adhesive.
In at least one embodiment, the releasing film 206 can be made of polyethylene terephthalate. The releasing film 206 can protect the adhesive layer 205 and maintain cleanliness and adhesive properties of the adhesive layer 205.
The second polarizer 30 can be substantially similar in structure to the polarizer 20. The second polarizer 30 can include a first section 31 and a second section 32. The first section 31 can be substantially rectangular and be located in a substantially central portion of the second polarizer 30. The first section 31 can be aligned with the display area 101. The second section 32 can be substantially rectangular and surround the first section 31. The second section 32 can be aligned with the non-display area 102. The second polarizer 30 can define at least one second through hole 321 in the second section 32 between every two adjacent corners of the second section 32. In the illustrated embodiment, two second through holes 32 are defined between every two adjacent corners of the second section 32. In at least one embodiment, a shortest distance between the second through holes 321 and the first section 31 is less than a shortest distance between the second through holes 321 and an outer edge of the second section 32. In another embodiment, the second polarizer 30 does not define the second through holes 321.
The backlight assembly 50 can include a back frame 55, a light source 51, a light guide plate 52, an optical film set 53, and a reflector 54. The back frame 55 can include a first piece 551, a second piece 552, a third piece 553, and a fourth piece 554 connected end-to-end. Each of the first piece 551, the second piece 552, the third piece 553, and the fourth piece 554 can include an inserting piece 556 protruding from a surface of the corresponding first piece 551, second piece 552, third piece 553, and fourth piece 554 facing toward the liquid crystal display panel 10. The inserting pieces 556 can be inserted into the corresponding second through holes 321 defined in the second polarizer 30. The number and positions of the inserting pieces 556 correspond to the number and positions of the through holes 32.
As illustrated in
The back frame 55 can include a base plate 555. The first piece 551, the second piece 552, the third piece 553, and the fourth piece 554 of the back frame 55 can be arranged on the base plate 555. The base plate 555, the first piece 551, the second piece 552, the third piece 553, and the fourth piece 554 can cooperatively define a receiving space for receiving the light guide plate 52 and the optical film set 53 therein. A side of the first piece 551 facing toward the light guide plate 52 can define a groove 5511 for receiving the light source 51 therein. In the illustrated embodiment, the light source 51 emits light into a side of the light guide plate 52. In another embodiment, the light source 51 can emit light from a bottom of the light guide plate 52 or from another position relative to the light guide plate 52. In at least one embodiment, the light source 51 is a light emitting diode. In other embodiments, the light source 51 can be another kind of light.
Referring again to
In at least one embodiment, the adhesive layer of the polarizer 20 and the second polarizer 30 can include a plurality of diffusion particles to allow diffusion of light. Thus, a diffusion layer is not required.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including, the full extent established by the broad general meaning of the terms used in the claims.
