Description

Technical Field

[0001] This invention relates to the field of integrated imaging display, and in particular to a wide-viewing-angle integrated imaging driving method and driving system. Background Technology

[0002] Integrated imaging is an automated stereoscopic and multi-view 3D imaging technology. Its core feature lies in using a two-dimensional microlens array (also known as a fly-eye lens) to capture and reproduce the light field. This technology eliminates the need for large integrated objectives or observation lenses. Instead, it uses a microlens array to record and reproduce light from different angles, creating a 3D visual effect that includes depth information. Specifically, integrated imaging technology includes two main processes: recording and reproduction. During recording, the microlens array records information about the object's spatial scene onto film. Each microlens captures a portion of the scene information from a different direction, generating tiny images (i.e., image pixels) from different perspectives. During reproduction, using the same microlens array as during recording, the light from the image pixels is focused and restored using the principle of optical reversibility, reproducing a 3D image of the object's spatial scene.

[0003] In existing technologies, the horizontal viewing angle of integrated imaging 3D displays is generally 1:1. In order to meet the requirements of a wide viewing angle, the vertical resolution of the display is often reduced at the same time. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide an integrated imaging multi-mode adjustable viewing angle display system based on a liquid crystal lens. The system aims to control the driving form of the first driving electrode group and the second driving electrode group according to the intended operating mode, thereby achieving switching between a normal mode and a wide viewing angle mode. Specifically, in the wide viewing angle mode, a driving voltage is applied to the first electrode group relative to the second electrode group. Since the first electrode group is elliptical (with the horizontal axis as the major axis), it forms a quasi-elliptical lens, thus achieving an integrated imaging lens with a wide viewing angle. In the normal mode, a driving voltage is applied to the second electrode group relative to the first electrode group, forming a quasi-circular lens. The present invention, with compatibility, can achieve wide viewing angle integrated imaging as needed, avoiding a decrease in vertical resolution.

[0005] To achieve the above objectives, in a first aspect of the present invention, a wide-view integrated imaging driving system is provided, the system comprising:

[0006] The mode setting module is used to obtain the working mode that the system intends to switch to; the working modes include: wide-view mode and normal mode;

[0008] A liquid crystal lens group is disposed in front of the 2D display array. The liquid crystal lens group includes: a first substrate, a first electrode group arranged in an array on the first substrate, a liquid crystal layer, a second electrode group arranged in an array on a second substrate, and a second substrate. The first electrode group includes at least two nested elliptical ring electrodes. The major axis of the elliptical ring electrode is parallel to the horizontal axis of the liquid crystal lens group, and the minor axis of the elliptical ring electrode is parallel to the vertical axis of the liquid crystal lens group. The second electrode group includes at least two nested circular ring electrodes. In the wide viewing angle mode, the first electrode group is used to apply a first relative driving voltage relative to the second electrode group to drive the liquid crystal layer to deflect and form a first lens, wherein the first lens is an elliptical lens whose length along the horizontal axis is greater than that along the vertical axis. In the normal mode, the second electrode group is used to apply a second relative driving voltage relative to the first electrode group to drive the liquid crystal layer to deflect and form a second lens, wherein the second lens is a circular lens.

[0009] And the main controller;

[0010] The main controller is configured as follows:

[0011] Receive a first switching instruction sent by the mode setting module to switch to the desired working mode; the first switching instruction includes the desired first working mode to switch to.

[0012] In response to the first operating mode being the wide viewing angle mode, the liquid crystal lens group is controlled to operate in the wide viewing angle mode, and the 2D display array is controlled to display the first source corresponding to the wide viewing angle mode; in response to the first operating mode being the normal mode, the liquid crystal lens is controlled to operate in the normal mode, and the 2D display array is controlled to display the second source corresponding to the normal mode.

[0013] In one specific embodiment, in the wide-viewing-angle mode, the second electrode group adopts a first common potential to make the second electrode group serve as a first common electrode, and the first electrode group applies a first relative driving voltage relative to the first common electrode; in the normal mode, the first electrode group adopts a second common potential to make the first electrode group serve as a second common electrode, and the second electrode group applies a second relative driving voltage relative to the second common electrode.

[0014] In one specific embodiment, a first high-resistance electrical connection layer is provided between the elliptical ring electrodes in the first electrode group; and a second high-resistance electrical connection layer is provided between the circular ring electrodes in the second electrode group.

[0015] In one specific embodiment, in the wide-view mode, the first horizontal-to-vertical viewing angle ratio of the first lens is greater than 1; in the normal mode, the second horizontal-to-vertical viewing angle ratio of the second lens is 1:1; wherein, the horizontal-to-vertical viewing angle ratio is the ratio of the horizontal viewing angle to the vertical viewing angle of the integrated imaging.

[0016] In one specific embodiment, a third electrode is further disposed between the first electrode groups on the first substrate, and an insulating gap is disposed between the third electrode and the first electrode groups; a fourth electrode is disposed between the second electrode groups on the second substrate, and an insulating gap is disposed between the fourth electrode and the second electrode groups; and when the system is in the wide viewing angle mode, the fourth electrode is connected to the first common electrode; when the system is in the normal mode, the third electrode is connected to the second common electrode.

[0017] In one specific embodiment, the first electrode group and the second electrode group are arranged in an array according to their respective arrangement spacing.

[0018] In one specific embodiment, the area sizes of the M first electrode groups correspond to the N second electrode groups, and they are arranged in a relative array; M and N are positive integers.

[0019] A second aspect of the present invention provides a wide-view integrated imaging driving method, the method being applied to the system provided in the first aspect above, the method comprising:

[0020] Receive a first switching instruction sent by the mode setting module to switch to the desired working mode; the first switching instruction includes the desired first working mode to switch to.

[0021] In response to the first working mode being the wide viewing angle mode, the liquid crystal lens group is controlled to work in the wide viewing angle mode, and the 2D display array is controlled to display the first source material corresponding to the wide viewing angle mode;

[0022] In response to the first working mode being the normal mode, the liquid crystal lens is controlled to work in the normal mode, and the 2D display array is controlled to display the second source corresponding to the normal mode.

[0023] The beneficial effects of the present invention are as follows: (1) In the present invention, the driving form of the first driving electrode group and the second driving electrode group is controlled according to the working mode to which the system is to switch, so as to realize the switching between the normal mode and the wide viewing angle mode; wherein, in the wide viewing angle mode, the first electrode group applies a driving voltage relative to the second electrode group. Since the first electrode group is elliptical (the horizontal axis is the major axis), it forms an elliptical lens and realizes a wide viewing angle integrated imaging lens; in the normal mode, the second electrode group applies a driving voltage relative to the first electrode group to form a circular lens. The present invention can realize wide viewing angle integrated imaging according to the requirements when compatible, and avoid the decrease in vertical resolution.

[0032] like Figure 1-Figure 5 As shown, an embodiment of the present invention provides a wide-view integrated imaging driving system, characterized in that the system includes:

[0033] The mode setting module is used to obtain the working mode that the system intends to switch to; the working modes include: wide-view mode and normal mode;

[0034] 2D display array;

[0035] A liquid crystal lens group 100 is disposed in front of the 2D display array. The liquid crystal lens group 100 includes: a first substrate 101, a first electrode group 102 arranged in an array on the first substrate 101, a liquid crystal layer 105, a second electrode group 104 arranged in an array on a second substrate 103, and the second substrate 103. The first electrode group 102 includes at least two nested elliptical annular electrodes 106. The major axis of the ellipse of the elliptical annular electrode is parallel to the horizontal axis of the liquid crystal lens group 100, and the minor axis of the ellipse of the elliptical annular electrode is parallel to the horizontal axis of the liquid crystal lens group 100. The vertical axis is 0; the second electrode group 104 includes at least two nested circular ring electrodes 107; wherein, in the wide viewing angle mode, the first electrode group 102 is used to apply a first relative driving voltage relative to the second electrode group 104 to drive the liquid crystal layer 105 to deflect and form a first lens, the first lens being an elliptical lens longer along the horizontal axis than along the vertical axis; in the normal mode, the second electrode group 104 is used to apply a second relative driving voltage relative to the first electrode group 102 to drive the liquid crystal layer 105 to deflect and form a second lens, the second lens being a circular lens;

[0036] And the main controller;

[0037] The main controller is configured as follows:

[0038] Receive a first switching instruction sent by the mode setting module to switch to the desired working mode; the first switching instruction includes the desired first working mode to switch to.

[0039] In response to the first operating mode being the wide viewing angle mode, the liquid crystal lens group 100 is controlled to operate in the wide viewing angle mode, and the 2D display array is controlled to display the first source corresponding to the wide viewing angle mode; in response to the first operating mode being the normal mode, the liquid crystal lens is controlled to operate in the normal mode, and the 2D display array is controlled to display the second source corresponding to the normal mode.

[0040] It is worth mentioning that the first electrode group 102 includes at least two nested elliptical ring electrodes 106. The specific number of elliptical ring electrodes 106 can be set according to actual needs. Typically, the more elliptical ring electrodes 106 there are, the smoother the curvature of the first lens will be, and the better the integrated imaging effect will generally be.

[0041] Typically, in the wide viewing angle mode, the first electrode group 102 is used to apply a first relative driving voltage relative to the second electrode group 104 to drive the liquid crystal layer 105 to deflect and form a first lens. In fact, at this time, the sub-electrodes in the second electrode group 104 can use different voltages, and the first electrode group 102 can be driven to form the first lens by applying the first relative driving voltage relative to the respective sub-electrodes of the corresponding second electron group. Correspondingly, the second lens is also the same.

[0042] In the preferred embodiment, in the wide viewing angle mode, the second electrode group 104 can adopt a first common potential and be used as the first common electrode. At this time, each sub-electrode in the first electrode group 102 is given a first relative driving voltage, which can drive the liquid crystal layer 105 to form a first lens.

[0043] Preferably, in this embodiment, in the wide viewing angle mode, the second electrode group 104 adopts a first common potential to make the second electrode group 104 serve as the first common electrode, and the first electrode group 102 applies the first relative driving voltage relative to the first common electrode; in the normal mode, the first electrode group 102 adopts a second common potential to make the first electrode group 102 serve as the second common electrode, and the second electrode group 104 applies the second relative driving voltage relative to the second common electrode.

[0044] Preferably, in order to improve the smoothness of driving liquid crystal deflection and reduce lens distortion when used as a common electrode, in this embodiment, a first high-resistivity electrical connection layer 109 is provided between the elliptical ring electrodes 106 in the first electrode group 102; and a second high-resistivity electrical connection layer 108 is provided between the circular ring electrodes 107 in the second electrode group 104. Of course, when the design requirements are low, i.e., within the acceptable range of distortion design, the high-resistivity electrical connection layer may not be provided.

[0045] Typically, in the wide-view mode, the first aspect ratio of the first lens is greater than 1; in the normal mode, the second aspect ratio of the second lens is 1:1; wherein, the aspect ratio is the ratio of the lateral view to the longitudinal view of the integrated imaging.

[0046] Optionally, a third electrode is further disposed between the first electrode groups 102 on the first substrate 101, and an insulating gap is disposed between the third electrode and the first electrode group 102; a fourth electrode is disposed between the second electrode groups 104 on the second substrate 103, and an insulating gap is disposed between the fourth electrode and the second electrode group 104; and when the system is in the wide viewing angle mode, the fourth electrode is connected to the first common electrode; when the system is in the normal mode, the third electrode is connected to the second common electrode.

[0047] Optionally, the first electrode group 102 and the second electrode group 104 are arranged in their respective arrays according to their respective spacing. In fact, since they serve as common electrodes, the arrays on both sides do not need to be matched.

[0048] To reduce the risk of distortion, alternatively, the area sizes of M first electrode groups 102 can correspond to N second electrode groups 104, and they can be arranged in a relative array; M and N are positive integers.

[0049] like Figure 3 In terms of array arrangement, Figure 3 -a corresponds to 4 second electrode groups 104 Figure 3 -b contains two first electrode groups 102; such as Figure 4 As shown, in terms of array arrangement, in Figure 4 -a corresponds to 104 of the second electrode group Figure 4 -b contains two first electrode groups 102; while for Figure 5 In terms of the number of electrodes in the array, the second electrode group 104 and the first electrode group 102 are not related.

[0050] A second embodiment of the present invention provides a wide-view integrated imaging driving method, which is based on the driving system provided in the first embodiment, and the method includes:

[0051] Receive a first switching instruction sent by the mode setting module to switch to the desired working mode; the first switching instruction includes the desired first working mode to switch to.

[0052] In response to the first working mode being the wide viewing angle mode, the liquid crystal lens group 100 is controlled to work in the wide viewing angle mode, and the 2D display array is controlled to display the first source material corresponding to the wide viewing angle mode;

[0053] In response to the first working mode being the normal mode, the liquid crystal lens is controlled to work in the normal mode, and the 2D display array is controlled to display the second source corresponding to the normal mode.

[0054] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort.
