Example 1
As shown in fig. 1, the present utility model provides a liquid crystal lenticular lens comprising a first substrate 10, a first electrode layer 20, a first alignment layer 30, a liquid crystal layer 40, a second alignment layer 50, a second electrode layer 60, and a second substrate 70, which are sequentially stacked;
referring to fig. 1, the liquid crystal lenticular lens of the present embodiment adopts a layered arrangement in which a liquid crystal layer 40 is sandwiched between a first alignment layer 30 and a second alignment layer 50. The first substrate 10 is disposed at a side of the first alignment layer 30 remote from the liquid crystal layer 40. The first substrate 10 is disposed with a first electrode layer 20 on a surface of the first substrate 10 near the liquid crystal layer 40, wherein the first electrode layer 20 may be plated on the surface of the first substrate 10. The present embodiment provides the second substrate 70 at a side of the second alignment layer 50 away from the liquid crystal layer 40. The second substrate 70 is provided with a second electrode layer 60 at a side close to the liquid crystal layer 40, wherein the second electrode layer 60 may be plated on a surface of the second substrate 70. The second substrate 70, the second electrode layer 60, the second alignment layer 50, the liquid crystal layer 40, the first alignment layer 30, the first electrode layer 20, and the first substrate 10 are sequentially seen in the light passing direction of the liquid crystal two-group lenses.
Since the first electrode layer 20 is a planar electrode, the first electrode layer 20 may form an equipotential plane when a voltage is applied to the first electrode layer 20.
As shown in fig. 2, the second electrode layer 60 includes an electrode unit 12 set 1, and the electrode unit 12 set 1 includes a plurality of electrode units 12 disposed along a first direction. The number of the electrode units 12 in the electrode unit 12 group 1 is greater than or equal to 2. Wherein the first direction is the axial direction of the liquid crystal lenticular lens, i.e., the x-direction in fig. 2.
As shown in fig. 3, in this embodiment, the electrode unit 12 includes a potential distribution wire 121 and a plurality of suspended wires 125 parallel to each other, as shown in fig. 4, a first position 122 for receiving a first voltage and a second position 123 and a third position 124 for receiving a second voltage are disposed on the potential distribution wire 121, the first position 122 is located between the second position 123 and the third position 124, one end of the suspended wire 125 is connected to the potential distribution wire 121 between the second position 123 and the third position 124, the opposite end is suspended, the positions of the different suspended wires 125 connected to the potential distribution wire 121 are different, and the resistance value between the connection position of each suspended wire 125 of the potential distribution wire 121 to the first position 122 and the distance between the connection position of the suspended wire 125 to the potential distribution wire 121 to the first position 122 in the second direction satisfy a first condition; wherein the first voltage and the second voltage are different. And the first direction and the second direction are perpendicular, and the suspended line 125 of each of the electrode units 12 is parallel to the first direction. Wherein the second direction is the y-direction in fig. 3.
When a first voltage is applied at the first location 122 of the potential distribution wire 121, a second voltage is applied at the second location 123 and a third location 124 of the potential distribution wire 121, the magnitude of the potential on the potential distribution wire 121 will vary with the location of the potential distribution wire 121, thereby providing a variety of different magnitudes of potential to the suspended wire 125 in the electrode unit 12. Because one end of the suspended wire 125 is connected to the potential distribution wire 121 and the other end is suspended, the potential at each position on the suspended wire 125 is ideally equal to the potential at the position on the potential distribution wire 121 where the suspended wire 125 is connected. Based on the aforementioned structural features, the present embodiment can select the connection position of the suspended line 125 and the potential distribution wire 121 according to the desired potential on the suspended line 125, and precisely control the potential distribution around the liquid crystal lens by using the position of the space around the liquid crystal lens through which the suspended line 125 passes.
Since the potential at a certain position on the potential distribution wire 121 after the first voltage and the second voltage are applied in the foregoing manner depends on the magnitude of the resistance value between the position to the first position 122, the present embodiment can control the potential distribution of the liquid crystal lenticular lens by configuring the condition satisfied by the connection position of each suspended wire 125 to the potential distribution wire 121 and the distance between each suspended wire 125 in the second direction to the first position 122, that is, the foregoing first condition. The resulting potential distribution is also different for different first conditions, and the corresponding liquid crystal lenticular lens types are also different. With the above structure, the electric potential on each suspension line 125 can be precisely controlled, and the spatial position where each suspension line 125 passes can be precisely controlled, so that the present embodiment can realize precise control of the electric potential distribution of the liquid crystal lens in an ideal case.
However, in practical use, the potential on the suspended line 125 gradually decreases along with the extension of the suspended line 125, and when the length of the suspended line 125 is longer, the potential of a portion of the suspended line 125 further from the potential distribution wire 121 is significantly weaker than the potential at the connection position of the suspended line 125 and the potential distribution wire 121, so that the potential distribution of the liquid crystal lens cannot meet the practical requirements. As shown in fig. 2, in this embodiment, a plurality of electrode units 12 are sequentially arranged along the first direction, and when the potential of the previous electrode unit 12 is weakened to a certain extent, the immediately following electrode unit 12 is used as a relay, so that the potential can be timely restored to an ideal magnitude, and the deterioration of the liquid crystal lenticular lens effect caused by the gradual weakening of the potential is effectively avoided.
As one of the embodiments, the present embodiment provides a liquid crystal lenticular lens of a parabolic cylinder, wherein the first condition is satisfied that the resistance value between the position where each suspended line 125 of the electric potential distribution wire 121 is connected to the electric potential distribution wire 121 and the first position 122 and the distance between each suspended line 125 and the first position 122 in the second direction are parabolic.
The parabolic distribution of the resistance value between the position of each suspended line 125 of the potential distribution wire 121 connected to the potential distribution wire 121 and the distance from each suspended line 125 to the first position 122 in the second direction is obtained by establishing a rectangular coordinate system in which the correspondence relationship between the resistance value between the position of each suspended line 125 of the potential distribution wire 121 connected to the potential distribution wire 121 and the distance from each suspended line 125 to the first position 122 in the second direction is parabolic, using the resistance value between the position of each suspended line 125 connected to the first position 122 and the distance value between the distance from each suspended line 125 to the first position 122 in the second direction as coordinate axes.
As one of the embodiments, the present embodiment provides a liquid crystal lenticular lens having a tapered surface in cross section, wherein the first condition is satisfied in which the resistance value between the position where each suspended line 125 of the potential distribution wire 121 is connected to the potential distribution wire 121 and the first position 122 is linearly distributed with the distance from each suspended line 125 to the first position 122 in the second direction.
The fact that the resistance value between the position where each suspended wire 125 of the potential distribution wire 121 is connected to the potential distribution wire 121 and the distance between each suspended wire 125 and the first position 122 in the second direction are linearly distributed means that a rectangular coordinate system is established with the resistance value between the position where each suspended wire 125 is connected to the first position 122 and the distance between each suspended wire 125 and the first position 122 in the second direction as coordinate axes, and a curve representing the correspondence between the resistance value between the position where each suspended wire 125 of the potential distribution wire 121 is connected to the potential distribution wire 121 and the distance between each suspended wire 125 and the first position 122 in the second direction is a slant line.
As an alternative embodiment, the length of the suspended line 125 of each electrode unit 12 is the same in this embodiment. By adopting the mode, the electric potential in the axial direction of the liquid crystal column lens can be kept to be uniform in the whole.
As an alternative embodiment, the length of the suspended line 125 of each electrode unit 12 is different in this embodiment. Wherein the length of the suspended wire 125 may be determined based on the decay of the potential during actual use. When the potential attenuation of the suspended wire 125 does not meet the use requirement, it is necessary to reduce the length of the suspended wire 125 and to dispose the next electrode unit 12 at a position near the end of the suspended wire 125 so that the potential of the liquid crystal lens is restored to the desired magnitude.
As an alternative but advantageous embodiment, the ends of the respective suspension wires 125 of the preceding one of the electrode units 12 are spaced apart from the tips of the potential distribution wires 121 of the following one of the electrode units 12 by the same distance in the present example. Wherein the end of the suspended wire 125 refers to the end of the suspended wire 125 remote from the potential distribution wire 121 to which it is connected. The electrode unit 12 adjacent to the suspended line 125 is the previous electrode unit 12, and the electrode unit 12 adjacent to the potential distribution wire 121 is the next electrode unit 12.
Since the lengths of the potential distribution wires 121 in the first direction may be different, if the respective suspension wires 125 of the previous electrode unit 12 are set to the same length, a situation in which the previous electrode unit 12 and the next electrode unit 12 cannot be joined in time is likely to occur. In this embodiment, the end of each suspended wire 125 of the previous electrode unit 12 is controlled to be spaced from the top end of the potential distribution wire 121 of the next electrode unit 12 by the same distance, so that the suspended wire 125 of the previous electrode unit 12 and the potential distribution wire 121 of the next electrode unit 12 can be better connected, and the electric potential of the liquid crystal lenticular lens along the first direction can be kept to be better consistent.
As an alternative but advantageous embodiment, the suspension lines 125 of two adjacent electrode units 12 are in one-to-one correspondence in the present embodiment, and the suspension lines 125 of two adjacent electrode units 12 corresponding to each other are on the same straight line. Wherein the one-to-one correspondence of the suspension lines 125 of two adjacent electrode units 12 means that the number of suspension lines 125 of two adjacent electrode units 12 is the same, and each suspension line 125 of the previous electrode unit 12 corresponds to one of the suspension lines 125 of the next electrode unit 12. And the positions of the respective suspension lines 125 of the preceding electrode unit 12 in the second direction are the same as the positions of the respective suspension lines 125 of the following electrode unit 12 in the second direction in the present embodiment. By adopting the structure, the electric potentials at all positions in the first direction of the liquid crystal lens can be made to have better consistency, so that the liquid crystal column lens with better effect is formed.
In this embodiment, as an alternative but advantageous embodiment, the width of the portion of the potential distribution wire 121 between the second location 123 and the third location 124 is the same. Since the resistance value between the connection position of each suspended wire 125 on the potential distribution wire 121 to the potential distribution wire 121 and the first position 122 is proportional to the length of the potential distribution wire 121 from the connection position of each suspended wire 125 to the potential distribution wire 121 to the first position 122 with the same width between the second position 123 and the third position 124 of the potential distribution wire 121, the present embodiment can control the potential on the suspended wire 125 by controlling the length of the potential distribution wire 121 between the connection position of the suspended wire 125 to the potential distribution wire 121 and the first position 122.
As one of the embodiments, in this example, the length of the potential distribution wire 121 from the position where each suspended line 125 is connected to the potential distribution wire 121 to the first position 122 and the distance from each suspended line 125 to the first position 122 in the second direction are parabolic, and the obtained liquid crystal lenticular lens is a parabolic liquid crystal lenticular lens.
As one of the embodiments, the length of the potential distribution wire 121 from the position where each of the suspended wires 125 is connected to the potential distribution wire 121 to the first position 122 is linearly distributed with the distance or the linear distribution of each of the suspended wires 125 to the first position 122 in the second direction in the present embodiment. The liquid crystal lenticular lens obtained at this time is a liquid crystal lenticular lens having a tapered surface in cross section.
In addition, the present embodiment may further provide a high-resistance film or a high-dielectric constant layer, wherein the high-resistance film or the high-dielectric constant layer may be disposed between the second electrode layer 60 and the second alignment layer 50, or may be disposed between the second electrode layer 60 and the second transparent substrate. The high-resistance film or high-dielectric constant layer may make the potential between adjacent suspended lines 125 smoother.

Each electrode unit 12 set 1 may form a liquid crystal lenticular lens unit, and the plurality of electrode unit 12 sets 1 may form a plurality of liquid crystal lenticular lens arrays arranged along the second direction. Since the electrode unit 12 set 1 in this embodiment employs a plurality of electrode units 12 arranged along the first direction, the electrode unit 12 of the latter can recover the potential to the desired level in time after the potential of the suspended line 125 of the electrode unit 12 of the former is reduced to a certain extent, so that the liquid crystal lens can be used as a liquid crystal lens to maintain the desired potential distribution, thereby improving the effect of the liquid crystal lens.
As shown in fig. 5, the potential distribution wires 121 in the adjacent electrode unit 12 groups 1 are connected, so that the arrangement of the liquid crystal lenticular lens array is more compact.
As shown in fig. 6, wherein the adjacent electrode unit 12 groups 1 are spaced apart in the second direction by a preset distance, the preset distance may be determined according to the arrangement positions of the respective liquid crystal lenticular lens units in the liquid crystal lenticular lens array.
