Description
Technical Field
The present invention relates to an optical assembly for a 2D/3D switchable display, and more particularly, to a liquid crystal lens assembly for providing a 3D display function in a 2D/3D switchable display, and more particularly, to a display having a liquid crystal lens assembly for a 2D/3D switchable display.
Background
Currently, attention is paid to 2D/3D switchable displays, for example, the following chinese patent applications CN201110209362.8, CN201210183246.8, CN 201010512421.4 and CN201410048596.2 describe the structure of the existing 3D display and the working and switching principle of 2D/3D in detail. The commonly used operating principle of the lenticular liquid crystal lens is as follows: when an LCD (Liquid Crystal Display) panel emits linearly polarized light with a specific direction and then passes through the birefringent layer, and the phase retardation value of the birefringent layer is adjusted to be positive multiple of the wavelength, the light emitted by the LCD panel does not change in polarization after passing through the birefringent layer, so that a Liquid Crystal lens assembly positioned above the birefringent layer does not act as a lens to enable the light to directly pass through, and the Display has a 2D effect; when the phase retardation value of the birefringent layer is adjusted to be 1/2, the light emitted by the LCD panel is changed in polarization by 90 degrees after passing through the birefringent layer, and the liquid crystal lens assembly located above the birefringent layer can play a lens role, so that the display has a 3D effect. The background of CN201110209362.8 and CN201210183246.8 are described in detail in the above working principle, and those skilled in the art can understand the above prior art, and the contents are incorporated herein by reference.
Fig. 1 shows a typical structure of a liquid crystal lens assembly of a 2D/3D switchable display, which mainly includes an upper substrate 11, a liquid crystal layer 12, and a lower substrate 13, wherein a plurality of concave lens columns 14 with concave arc-shaped cross sections are formed in parallel on a side of the lower substrate 13 facing the liquid crystal layer 12. The upper substrate 11 may be provided with an alignment film 15 (or without an alignment film) on its side facing the liquid crystal layer 12, and the lower substrate 13 may be provided with associated electrode traces, etc., as required by different applications. When the liquid crystal lens assembly is assembled, due to the deflection of the materials of the layers and the uneven stress in operation, a part of continuous large-area contact (a part of continuous large-area contact with the upper substrate 11 in the case of no alignment film 15) is generated between the bonding part 140 of the adjacent concave lens column 14 and the alignment film 15 above the bonding part, so that a stripe phenomenon of uneven brightness as shown in fig. 2 occurs, and the larger the area of continuous contact between the two is, the more obvious the stripe is displayed, thereby reducing the display effect when the front view is performed.

Detailed Description
In order to more clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will now be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.
Fig. 3 is a schematic structural diagram of a liquid crystal lens assembly for a 2D/3D switchable display according to an embodiment of the present invention, and similar to the liquid crystal lens assembly of the typical structure mentioned in the background section, the liquid crystal lens assembly 1 of the present invention also includes an upper substrate 11, a liquid crystal layer 12, and a lower substrate 13 sequentially stacked, the lower substrate 13 having a first side 131 facing the liquid crystal layer 12 and a second side 132 opposite to the first side 131, and a plurality of concave lens columns 14 having a concave arc-shaped cross section and arranged in parallel are formed on the first side 131. In the embodiment shown in fig. 3, the upper substrate 11 is provided with an alignment film 15 on the side facing the liquid crystal layer 12, but it should be understood by those skilled in the art that the alignment film 15 may be omitted in another embodiment of the present invention according to different application requirements. In addition, related electrode lines (not shown) may be provided on the upper substrate 11 and the lower substrate 13, or only the upper substrate 11 or the lower substrate 13 may be provided with the electrode lines.
Unlike the background art, in the embodiment shown in fig. 3, two different types of bonding portions 141 and 142 are formed between the adjacent concave lens columns 14, that is, either the first bonding portion 141 or the second bonding portion 142 is formed between the adjacent concave lens columns 14. The two different types of bonds 141, 142 differ in their maximum vertical height relative to the first side 131 of the lower substrate 13.
Specifically, the two different types of bonding portions 141 and 142 include a first bonding portion 141 having a first height h1 with respect to the maximum vertical height of the first side 131 and a second bonding portion 142 having a second height h2 with respect to the maximum vertical height of the first side 131, wherein the first height h1 is greater than the second height h2, and the first bonding portion 141 and the second bonding portion 142 are uniformly distributed between the adjacent concave lens pillars 14. That is, in the above embodiment, the junctions of different height patterns are formed between the adjacent concave lens columns 14, and the junctions have different heights, and the junctions of different heights are uniformly distributed.
In the liquid crystal lens assembly provided by the invention, the first combining part and the second combining part with two different heights are arranged, so that when the liquid crystal lens assembly is assembled, even if the combining parts of adjacent concave lens columns contact with the upper substrate or the alignment film above the combining parts due to the deflection of materials of all layers and uneven stress in operation, only the first combining part with the larger height contacts with the upper substrate or the alignment film, and the second combining part is erected by the first combining part and cannot contact with the upper substrate or the alignment film. The liquid crystal lens assembly has the advantages that the liquid crystal lens assembly can generate very fine local contact through the first bonding parts with larger heights which are arranged deliberately, the local contact is also uniformly distributed because the first bonding parts are uniformly distributed, the display difference generated by the uniformly distributed local contact is difficult to be perceived after being uniformly dispersed visually, the stripe caused by continuous large-area contact of the bonding parts similar to the background technology is completely avoided, the generation of the stripe is stopped fundamentally, and the defect of low display quality generated by the stripe is effectively solved.
The maximum vertical heights h1 and h2 relative to the first side 131 are mentioned in the above embodiments, and are defined to illustrate that the first combining portion 141 may have a highest point with a height h1 relative to the first side 131, and the second combining portion 142 may have a highest point with a height h2 relative to the first side 131. See in particular fig. 4 and 5.
Fig. 4 is a perspective view showing a concave lens column 14 of a liquid crystal lens assembly according to another embodiment of the present invention, and fig. 5 is a perspective view showing a concave lens column 14 of a liquid crystal lens assembly according to yet another embodiment of the present invention. As can be seen in fig. 4 and 5 in contrast, in the particular embodiment shown in fig. 4, the tops of the first and second bonding portions 141 and 142 are straight, and thus all points of the tops are the highest points. In the embodiment shown in fig. 5, the tops of the first and second coupling portions 141 and 142 are not straight and have an undulation, so that the top has one or more highest points, at least not every point having an equal height.
Specifically, in the specific embodiment shown in fig. 4, the first coupling portion 141 has a constant first height h1 along the length direction of the concave lens column 14, and the second coupling portion 142 has a constant second height h2 along the length direction of the concave lens column 14.
In the embodiment shown in fig. 5, the first coupling parts 141 have different heights along the length direction of the concave lens column 14, and the height difference h3 between the maximum vertical height and the minimum vertical height with respect to the first side 131 is greater than or equal to 0.5 μm.
In the embodiment shown in fig. 3 to 5, the top width of the cross section of the first coupling portion 141 is 0.5 μm or more, and the difference between the first height h1 and the second height h2 is 1 μm or more.
The above embodiments of the present invention provide specific parameter relationships of concave lens columns, and those skilled in the art can obtain better display effects according to the parameter relationships without any technical teaching in the prior art, and those skilled in the art cannot know what experiments can be used to obtain the parameter relationships without the parameter relationships as teaching, so that the parameter relationships provided by the above embodiments of the present invention are not obvious to those skilled in the art, have outstanding substantive features and significant progress, and have creativity in the meaning of patent law.
In addition, the solution of the first and second combining parts 141 and 142 provided in the embodiment shown in fig. 4 with flat top portions is a basic solution, which has a simple structure and is easy to implement, and can solve the technical solution to be solved by the present invention and achieve the expected effect. The scheme in fig. 5 is a further optimized scheme, in which the tops of the first bonding portion 141 and the second bonding portion 142 are not straight and have a height, so that when the first bonding portion 141 contacts the upper substrate or the alignment film above the first bonding portion, line contact is not generated as in the embodiment shown in fig. 4, but only local point contact is generated, which at least greatly reduces the contact area, thereby further reducing the length of the generated contact stripe and obtaining a better display effect.
Of course, in the embodiment shown in fig. 5, since the height of the first coupling portion 141 is higher, the second coupling portion 142 may be in an overhead state, and thus, the top of the second coupling portion 142 may be in a straight state as in the embodiment shown in fig. 4. Preferably, the top of the second bonding portion 142 is not flat, as shown in fig. 5, which has the advantage that if the second bonding portion 142 contacts with the upper substrate or the alignment film above the first bonding portion 141 in the area where the first bonding portion 141 is not completely overhead, the top of the second bonding portion 142 with the height may only make local point contact, and the length of the contact stripe may be further reduced, so as to obtain better display effect.
In addition, in order to obtain more excellent display effect, in one embodiment, the lower substrate 13 may be a homogeneous circuit board made of transparent material, and the thickness of the homogeneous circuit board is more than 0.3 mm.
In another embodiment, the refractive index of the concave lens columns 14 is preferably above 1.3 and below 1.6. Further, in order to reduce interference fringes, it is preferable that the width of the single concave lens column 14 is equal to 2 times or more the width of the pixel unit of the LCD panel.
In still another preferred embodiment, under normal outgoing light polarization conditions of the LCD panel, it is preferable that the liquid crystal layer 12 is an anisotropic liquid crystal having a refractive index equal to that of the concave lens columns 14 and a difference in refractive index between the two is 0.05 or less.
In addition, based on the above detailed description, the present invention can also provide a display device including the liquid crystal lens assembly.
Fig. 6 is a schematic structural diagram showing a specific example of applying the liquid crystal lens assembly 1 of the present invention to a display, where the display includes an LCD panel 2, and when the electrode lines disposed on the upper substrate 11 and/or the lower substrate 13 of the liquid crystal lens assembly 1 of the present invention have a function of driving the liquid crystal layer 12 to deflect, for example, similar to the technical solution disclosed in CN201210183246.8 mentioned in the background section, the liquid crystal lens assembly 1 of the present invention can be separately attached as a 2D/3D switchable imaging component on the outer side of the LCD panel 2 (the side of the LCD panel facing the viewer), and the liquid crystal lens assembly 1 in this solution can omit the alignment film shown in fig. 3.
Alternatively, as shown in fig. 7, in another specific example of a structure of a display device, which includes an LCD panel 2, when the liquid crystal lens assembly 1 of the present invention is only passively used as a 3D imaging component, a drivable birefringent layer 3 needs to be added on the outer side of the LCD panel 2, and the birefringent layer 3 is used as a switching layer for deflecting light. I.e. a birefringent layer 3 is arranged between the LCD panel 2 and the liquid crystal lens assembly 1, and then the liquid crystal lens assembly 1 of the present invention is attached to the outer side of the birefringent layer 3, the liquid crystal lens assembly 1 in this solution may comprise an alignment film 15.

The description is given for clearness of understanding only, and it is to be understood that all matters in the embodiments are to be interpreted as including technical equivalents which are related to the embodiments and which are combined with each other to illustrate the scope of the present invention.
