Fig. 1 shows a schematic top view of a liquid crystal glasses device according to an embodiment of the present disclosure, which employs a processing process and a driving manner of a double-layer driving electrode (i.e., a first driving electrode 105 and a second driving electrode 106), and some components (including a substrate, a liquid crystal alignment layer, a liquid crystal layer, a common electrode layer, etc.) are removed in order to clearly show an arrangement manner of the first driving electrode 105 and the second driving electrode 106. In some embodiments, various transparent driving electrodes may be used as the first driving electrode 105 and the second driving electrode 106, and the configuration of the liquid crystal glasses device is explained with ITO electrodes as an example.
As shown in fig. 1, the first drive electrode 105 and the second drive electrode 106 have concentric circumferential electrode portions that alternate with each other. For example, the concentric circumferential electrode portions may be in the shape of concentric circles/rings, i.e. concentric with the center of the circle. Although the concentric circumferential electrode portions are described below as being circular as an example, it should be understood that the shape of the concentric circumferential electrode portions is not limited thereto, and may be elliptical, or rectangular, as long as they are concentric and extend across the circumferential direction.
As an example of concentric circumferential electrode portions from the center to the edge, in fig. 1, the first drive electrode 105 includes a first circular electrode portion, a second circular electrode portion, and a third circular electrode portion (indicated by oblique lines) in the direction from the center to the edge, and the second drive electrode 106 includes a fourth circular electrode portion and a fifth circular electrode portion (indicated by a grid) in the direction from the center to the edge, wherein the fourth circular electrode portion is located between the first circular electrode portion and the second circular electrode portion, and the fifth circular electrode portion is located between the second circular electrode portion and the third circular electrode portion. The adjacent concentric circumferential electrode portions of the first drive electrode 105 and the second drive electrode 106 are at different heights (shown in fig. 2), the width of the concentric circumferential electrode portions decreasing in the direction from concentric to edge (as shown in fig. 1). The higher the correction power of the spectacles, the smaller the width of the fifth ring electrode portion of the edge. The liquid crystal glasses device comprises a control electrode 103 connected to said first 105 and second 106 drive electrodes. In some embodiments, the control electrodes 103 may be provided in one-to-one correspondence with concentric circumferential electrode portions and electrically connected thereto, for example, 5 control electrodes 103 are shown in fig. 1, electrically connected to the first, second, third, fourth and fifth circular electrode portions, respectively. The liquid crystal glasses device further comprises a controller 102, wherein the controller 102 controls the voltage provided by the control electrode 103 to the first driving electrode 105 and the second driving electrode 106 to adjust the electric field between the common electrode layer (shown in fig. 2) and the first driving electrode 105 and the second driving electrode 106, so that the liquid crystal layer (shown in fig. 2) achieves the target correction optical parameters, for example, the liquid crystal layer can be formed into a plurality of small cambered structures with different refractive indexes, thereby achieving the effects of convex lenses, concave lenses, astigmatism correction lenses and the like.
In some embodiments, the controller 102 may be implemented by any one of an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), a digital signal processing chip (DSP), a System On Chip (SOC), and the like, which is not described herein in detail, and may receive a control instruction from a processor to perform a corresponding adjustment operation, and of course, the processor and the controller may also be integrated together.
In some embodiments, the liquid crystal glasses device may further include a distance sensor 104 configured to measure a distance between the liquid crystal glasses and the eye (especially the eyeball) so as to implement an eyeball tracking technique in cooperation with the camera.
Fig. 2 shows a partial cross-sectional view along the line a-a 'and the line B-B' in fig. 1, respectively. Specifically, the cross-sectional view on the left side of the dividing line is a partial cross-sectional view taken along the line a-a 'in fig. 1, and the cross-sectional view on the right side of the dividing line is a partial cross-sectional view taken along the line B-B' in fig. 1.
The liquid crystal glasses device includes a controller, and as shown in fig. 2, further includes a first substrate 210, a control electrode layer 209, two- layer driving electrodes 207 and 208, a liquid crystal alignment layer 206 and a liquid crystal layer 203 therebetween, a common electrode layer 202, and a second substrate 201, which are sequentially stacked. The first drive electrode 207 and the second drive electrode 208 may be configured as two independent drive electrode layers. The second circular electrode portion, the fourth circular electrode portion, and half of the first circular electrode portion are shown from left to right in the left side of fig. 2, and the fifth circular electrode portion and the second circular electrode portion are shown from left to right in the right side of the figure, wherein adjacent circular/circular electrode portions are at different heights, and each circular/circular electrode portion is electrically connected to the control electrode layer 209, for example, by a recessed arc-shaped connection portion. The controller controls the voltage supplied by the control electrode layer 209 to the first and second driving electrodes 207 and 208 to adjust the electric field between the common electrode layer 202 and the first and second driving electrodes 207 and 208, so that the liquid crystal layer 203 achieves the target correction optical parameter.
In some embodiments, the first substrate 210 and the second substrate 201 may be glass or a flexible substrate material, in this example glass as the substrate. In some embodiments, an insulating layer 205, which may be composed of a silicon nitride or silicon oxide material, may be formed between the first and second driving electrodes 207 and 208. In some embodiments, a high resistance layer 204 is formed between the driving electrode adjacent to the liquid crystal alignment layer 206 of the first driving electrode 207 and the second driving electrode 208 and the liquid crystal alignment layer 206, and the high resistance layer 204 is added on the annular driving electrode, so that the radial electric field intensity of the liquid crystal layer 203 can be prevented from being sharply reduced, and the gradient electric field distribution is smoother. The high-resistance layer 204 and the liquid crystal layer 203 form a distributed RC circuit (the high-resistance layer 204 serves as a resistor, and the liquid crystal layer 203 serves as a capacitor), so that the purpose of softening electric field intensity reduction is achieved, and meanwhile, the liquid crystal display device can play a role of a flat layer.
Under the action of the gradient vertical electric field, the liquid crystal layer 203 rotates with the electric field, and the rotation angle of the liquid crystal is related to the direction of the electric field and the electric field intensity at the corresponding position, so that the phase difference of the liquid crystal at different positions is different, and the refractive index change similar to a lens is generated, for example, the orientation of the liquid crystal as shown in fig. 3(a) can realize a concave lens, and the orientation of the liquid crystal as shown in fig. 3(b) can realize a convex lens. Such a lens may be referred to as a liquid crystal lens and may be adapted to any polarization state, free from dependence on the polarization state of the incident light.
In some embodiments, the liquid crystal layer 203 may adopt blue phase liquid crystal, and may better implement modulation of natural light, as shown in fig. 3(a) and 3(b), and the phase difference distribution of such a liquid crystal lens is similar to that of a normal lens, and may achieve focusing or scattering effects.
In some embodiments, the power supply voltage of the control electrode can be adjusted to improve the voltage on the corresponding driving electrode, so as to change the correction optical parameters of the liquid crystal glasses device, especially the liquid crystal lens, including but not limited to at least one of the refractive index, the astigmatism, the equivalent curvature radius, the focal length, the concave lens and the convex lens.
Fig. 4 illustrates a schematic structural diagram of a liquid crystal glasses device according to an embodiment of the present disclosure. As shown in fig. 4, the liquid crystal glasses device may include a frame 401, a lens 402, a processor 404, and a camera 405, wherein the lens 402 may be configured with a transparent part having a corrective refractive parameter in various liquid crystal glasses devices according to the present disclosure, and a non-transparent wire or the like in various liquid crystal glasses devices according to the present disclosure may be accommodated in the frame 401. In some embodiments, the target corrective optical parameter may be a predetermined first corrective optical parameter, such as an eye power of 300 ° determined by recent historical data of the user, and the processor 404 may be configured to: based on the first corrective optical parameter, sending a control command to the controller to adjust the voltage provided by the control electrode layer 209 to the first driving electrode 207 and the second driving electrode 208, so that the liquid crystal layer 203 realizes the first corrective optical parameter. In particular, a correspondence between the first corrective optical parameter and the voltage provided by the control electrode may be established, for example, a corresponding list may be established, and the processor 404 may obtain the voltage provided by the control electrode based on the correspondence, for example, by looking up the list, and send a control command containing information of the voltage.
In some embodiments, the camera 405 may be a micro-porous camera, and the processor 404 may be a micro-computing processing unit, such as a single chip, to make the liquid crystal glasses more lightweight, compact, and aesthetically pleasing. In some embodiments, a camera 405 may be mounted on the side of the frame facing the wearer to capture a better quality eye image; the processor 404 can be embedded in the nose piece of the frame 401 to better utilize the installation space.
In some embodiments, an opto-electric converter 403 may be provided on the frame 401, particularly the temple arms, to generate electrical energy for use with an LCD eyewear device using light. Therefore, the design without power plug can be realized, and the liquid crystal glasses device can be conveniently used in wider scenes.
In some embodiments, the camera 405 is configured to monitor an eye image of the user and transmit to the processor 404, and the processor 404 is configured to, after the liquid crystal layer 203 achieves the first corrective optical parameter: determining an eyeball exposure area in a first period; comparing the eyeball exposure area with a preset threshold value, and sending a control instruction to the controller to adjust the voltage supplied by the control electrode layer 209 to the first driving electrode 207 and the second driving electrode 208 when the eyeball exposure area is smaller than the preset threshold value, so that the liquid crystal layer 203 realizes the refractive index corresponding to the second correction optical parameter required by the user. In this way, even if the current condition of the user's eyes changes from the recent historical data, the liquid crystal eyewear device can adjust adaptively to such a change in time, thereby realizing the second corrective optical parameters that accurately match the current condition of the user's eyes. Further, even if the preset first correction optical parameter deviates from the current situation of the user, the liquid crystal glasses device can correct the deviation in time.
By starting the adjustment based on the eyeball-capturing technique from the first correction optical parameter set in advance, the liquid crystal eyeglass device can avoid adjusting the correction optical parameter from the starting point which is far from the second correction optical parameter required by the user, thereby avoiding considerable workload of image-taking and image-processing of the eyeball in such a lengthy process, and significantly shortening the adjustment process.
In some embodiments, adjusting the voltage supplied by the control electrode layer 209 to the first drive electrode 207 and the second drive electrode 208 is performed in a plurality of times, each time increasing the corrective optical parameter achieved by the liquid crystal layer 203 by a predetermined parameter value, such as a predetermined degree of eye-glasses.
Fig. 5(a) shows a comparison diagram of eyes in a normal eye-opening state and an eye-squinting state, and it can be seen that the area of the glasses in the normal eye-opening state is significantly larger than the area of the eyes in the eye-squinting state.
Fig. 5(b) is a diagram showing the tracked eyeball areas at regular time intervals Δ T according to the embodiment of the disclosure, and it can be seen that the tracked eyeball areas in each time period within 7 Δ T exceed the preset threshold, thereby recognizing that the human eyes are not in a squinting state; the area of the eyeballs tracked in the two subsequent time periods is lower than a preset threshold value, so that the human eyes are determined to be in an eye squinting state at the moment.
Fig. 6 illustrates a flow chart for adjusting a corrective refractive parameter of a liquid crystal eyewear device in accordance with an embodiment of the present disclosure. As shown in fig. 6, the process begins in step 601, where the camera starts continuous monitoring of the eye, for example, capturing an image of the eye. Note that the monitoring of the camera and the subsequent adjustment process may be periodically turned on, for example, two months, and the adjustment system is turned off at other times to save power consumption.
The eye image is then transmitted to a processor, such as an image processor, to perform eye tracking techniques (step 602). And (4) judging whether the eyeball focuses on a distant object or not (step 603), if so, determining the naked area of the eyeball in one processing period delta T through an image processing technology (step 604), and otherwise, returning to the step 601 to continue the monitoring of the camera.
In step 605, the determined eyeball exposure area S and a preset threshold S are determinedThreshold(s)Comparing to determine whether the exposed area S of the eyeball is less than a preset threshold SThreshold(s). If not, the human eyes are not in an eye squinting state, the achieved correction refractive parameters can enable the user to correct the eyesight clearly, and the adjusting system is closed (Step 606). If so, the human eye is considered to be in an eye squinting state and the correction refractive parameter achieved is insufficient to clear the user's corrected vision, e.g., it may be determined that the degree of eye glasses does not match the user's actual condition (step 607). The desired regulated voltage may then be calculated by a processor (e.g., a computational processing unit) (step 608) and voltage regulation may be performed by the circuit control system. The adjustment can be performed gradually, for example, each time the adjustment increases the current degree of the glasses by 5 °, and then the return is made to determine whether the exposed area S of the eyeball is smaller than the preset threshold SThreshold(s)And determining whether the user can see the object clearly without squinting after the adjustment, and if the user can see the object clearly without squinting, closing the adjustment system. If the user still desires to squint, the flow continues through steps 607, 608 and 609 until the correction refractive parameters achieved have enabled the user to correct his or her vision clearly. The process can gradually adjust the correction refractive parameters to be accurately matched with the actual condition of the user, and the adjusting system can be closed in time after the accurate matching so as to solve the problem of power consumption and reduce the loss and aging of corresponding components.
