In practical applications, when the head-mounted device is used in an augmented reality or mixed reality scene, thecamera 15 needs to be used to acquire real images. However, when the head-mounted device is used for virtual display, thecamera 15 does not need to be applied.

具体的，液态镜头11可以用于将光线投射至用户的视网膜上，并在用户的视网膜上成像，以便于用户能够看到图像，所述图像可以包括虚拟图像或者现实图像中的至少一种，本申请实施例对此不做限定。Specifically, theliquid lens 11 can be used to project light onto the user's retina, and form an image on the user's retina, so that the user can see the image, and the image can include at least one of a virtual image or a real image, This embodiment of the present application does not limit it.

本申请实施例中，液态镜头11具体可以包括第一镜片111和第二镜片112，第一镜片111和第二镜片112可以围合形成用于容纳工作液体的容纳腔。第一镜片111和第二镜片112可以采用玻璃制成，以使得第一镜片111和第二镜片112既具备足够的强度支撑所述工作液体，同时，又具有较好的透光性能。In the embodiment of the present application, theliquid lens 11 may specifically include afirst lens 111 and asecond lens 112 , and thefirst lens 111 and thesecond lens 112 may surround and form an accommodating cavity for containing the working liquid. Thefirst lens 111 and thesecond lens 112 can be made of glass, so that thefirst lens 111 and thesecond lens 112 not only have sufficient strength to support the working fluid, but also have better light transmission performance.

本申请实施例中，液态镜头11内的工作液体可以包括导电的第一液体113和非导电的第二液体114这两种，其中，第一液体113为导电的水性液体，第二液体114为非导电的油性液体。这样，在第一液体113没有通入电压的情况下，第一液体113可以表现出亲水性，第二液体114则表现出抗水性，因此，第一液体113和第二液体114不混合，二者之间会形成光滑的像透镜一样的工作界面115。而且，工作界面115的聚焦特性可通过向第一液体113施加电压而变化(电润湿效应)。所述电压可以改变第一液体114表面与第二液体115表面的相互作用的方式，从而改变工作界面115的曲率。In the embodiment of the present application, the working liquid in theliquid lens 11 may include two kinds of conductivefirst liquid 113 and non-conductivesecond liquid 114, wherein thefirst liquid 113 is a conductive aqueous liquid, and thesecond liquid 114 is Non-conductive oily liquid. In this way, when no voltage is applied to thefirst liquid 113, thefirst liquid 113 can exhibit hydrophilicity, and thesecond liquid 114 can exhibit water resistance. Therefore, thefirst liquid 113 and thesecond liquid 114 do not mix, A smooth lens-like working interface 115 is formed between the two. Furthermore, the focusing properties of the workinginterface 115 can be changed by applying a voltage to the first liquid 113 (electrowetting effect). The voltage can change the way the surface of thefirst liquid 114 interacts with the surface of thesecond liquid 115 , thereby changing the curvature of the workinginterface 115 .

具体地，第二液体115的抗水表面的湿润效果可以通过施加在第一液体114上的电压来改变(即电润湿)，使其表面变得更亲水(湿润)或更抗水。由于原先抗水(或亲水)的表面现在变得更吸水(或抗水)，第二液体114的表面不得不改变其形式，因此，通过调整在第一液体113两端的电压，就可以改变两种不同的工作液体交接处的工作界面115的曲率，实现焦距的调整。这样，就可以使得经液态镜头11的光线的成像焦点能够落在用户的视网膜上，以在用户的视网膜上呈现出清晰的图像Specifically, the wetting effect of the water-repellent surface of thesecond liquid 115 can be altered (ie, electrowetting) by applying a voltage across thefirst liquid 114, making its surface more hydrophilic (wetting) or more water-resistant. Since the previously water-repellent (or hydrophilic) surface now becomes more water-absorbent (or water-resistant), the surface of thesecond liquid 114 has to change its form, so by adjusting the voltage across thefirst liquid 113, the The curvature of the workinginterface 115 at the junction of two different working liquids realizes the adjustment of the focal length. In this way, the imaging focus of the light passing through theliquid lens 11 can fall on the user's retina, so as to present a clear image on the user's retina

示例地，第一液体113可以包括但不局限于氯化钠、氯化钾溶液等能够导电且亲水的液体，第二液体114可以为氟油等不能够导电且抗水的液体。For example, thefirst liquid 113 may include but not limited to a conductive and hydrophilic liquid such as sodium chloride and potassium chloride solution, and thesecond liquid 114 may be a non-conductive and water-resistant liquid such as fluorine oil.

可选地，第一液体113和第二液体114的折射率不同，这样，在第一液体113与第二液体114之间的工作界面115的曲率发生变化的情况下，可以改变液态镜头11的聚焦参数，从而，改变液态镜头11的焦距。Optionally, thefirst liquid 113 and thesecond liquid 114 have different refractive indices, so that when the curvature of the workinginterface 115 between thefirst liquid 113 and the second liquid 114 changes, the curvature of theliquid lens 11 can be changed. The focus parameter, thus, changes the focal length of theliquid lens 11 .

在实际应用中，第一液体113的折射率可以大于第二液体114的折射率，或者，第一液体113的折射率还可以小于第二液体114的折射率，本申请实施例对此不做限定。In practical applications, the refractive index of thefirst liquid 113 may be greater than the refractive index of thesecond liquid 114, or the refractive index of thefirst liquid 113 may also be smaller than the refractive index of thesecond liquid 114, which is not done in this embodiment of the present application. limited.

如图3至图5所示，第一液体113可以靠近第一镜片111，第二液体114可以靠近所述第二镜片112，以使得第一液体113和第二液体114可以依次设置在第一镜片111和第二镜片112之间。在光线经过液态镜头11时，需要依次经过第一液体113、工作界面115以及第二液体114，这样，通过工作界面115的曲率的改变，即可改变液态镜头11的聚焦参数，从而，改变液态镜头11的焦距。3 to 5, thefirst liquid 113 can be close to thefirst lens 111, and thesecond liquid 114 can be close to thesecond lens 112, so that thefirst liquid 113 and thesecond liquid 114 can be arranged on the first lens in turn. between thelens 111 and thesecond lens 112 . When the light passes through theliquid lens 11, it needs to pass through thefirst liquid 113, the workinginterface 115, and thesecond liquid 114 in sequence. In this way, by changing the curvature of the workinginterface 115, the focusing parameters of theliquid lens 11 can be changed, thereby changing the liquid state. The focal length of thelens 11.

液态镜头11具有图3所示的平面镜状态、图4所示的凹镜状态以及图5所示的凸镜状态，电压控制模块12可以向第一液体113输出电压，以控制液态镜头11在所述平面镜状态、所述凹镜状态以及所述凸镜状态之间切换。其中，在所述平面镜状态，工作界面115为平面；在所述凹镜状态，工作界面115凹陷至第二液体114侧；在所述凸镜状态，工作界面115凹陷至第一液体113侧。在实际应用中，通过液态镜头11在不同状态之间的切换，可以使得液态镜头11可以适用不同视力的用户，在不同视力的用户的视网膜上皆可呈现出清晰的图像。Theliquid lens 11 has the plane mirror state shown in FIG. 3, the concave mirror state shown in FIG. 4, and the convex mirror state shown in FIG. switch between the plane mirror state, the concave mirror state and the convex mirror state. Wherein, in the plane mirror state, the workinginterface 115 is a plane; in the concave mirror state, the workinginterface 115 is recessed to thesecond liquid 114 side; in the convex mirror state, the workinginterface 115 is recessed to thefirst liquid 113 side. In practical applications, theliquid lens 11 can be adapted to users with different visions by switching theliquid lens 11 between different states, and clear images can be presented on the retinas of users with different visions.

例如，在用户为正常视力用户的情况下，电压控制模块12可以向第一液体113输出第一电压，以使工作界面115的曲率变化直至工作界面115变成平面，即图3所示的平面镜状态。在图3所示的平面镜状态下，液态镜头11相当于一个平面镜，通过液态镜头11的光线的成像焦点可以落在用户的视网膜上。For example, when the user is a user with normal vision, thevoltage control module 12 can output the first voltage to thefirst liquid 113, so that the curvature of the workinginterface 115 changes until the workinginterface 115 becomes a plane, that is, a flat mirror as shown in FIG. 3 state. In the plane mirror state shown in FIG. 3 , theliquid lens 11 is equivalent to a plane mirror, and the imaging focus of light passing through theliquid lens 11 can fall on the user's retina.

Through the adjustment function of the concave lens, the imaging focus of the light passing through theliquid lens 11 can be made to fall on the user's retina.

再如，在用户为近视眼用户的情况下，电压控制模块12可以向第一液体113输出第三电压，以使工作界面115的曲率变化直至工作界面115凹陷至第一液体113侧，即图5所示的凸镜状态。在图5所示的凸镜状态下，液态镜头11相当于一个凸透镜，通过所述凸透镜的调整功能，可以使得经液态镜头11的光线的成像焦点落在用户的视网膜上。For another example, when the user is a myopic user, thevoltage control module 12 may output a third voltage to thefirst liquid 113, so that the curvature of the workinginterface 115 changes until the workinginterface 115 is sunken to the side of thefirst liquid 113, that is, as shown in FIG. 5 shows the state of the convex mirror. In the state of the convex lens shown in FIG. 5 , theliquid lens 11 is equivalent to a convex lens.

That is, the first voltage may be greater than the second voltage and less than the third voltage. In this way, by adjusting the voltage output from thevoltage control module 12 to thefirst liquid 113, theliquid lens 11 can be switched between the plane mirror state, the concave mirror state and the convex mirror state.

如图3、图4和图5所示，液态镜头11还可以包括导电件126和绝缘件127。其中，导电件126与第一液体113连接，导电件126可以用于与电压控制模块12电连接，通入电压控制模块12输出的电压。绝缘件127可以设置在导电件126与第二镜片112之间，用于实现导电件126与第二镜片112之间的绝缘，避免漏电的缺陷。As shown in FIG. 3 , FIG. 4 and FIG. 5 , theliquid lens 11 may further include a conductive element 126 and an insulating element 127 . Wherein, the conductive member 126 is connected to thefirst liquid 113 , and the conductive member 126 can be used to electrically connect with thevoltage control module 12 and pass through the voltage output by thevoltage control module 12 .
