When the lens layer 131 is in a flat mirror state, the lens layer 131 makes the incident ambient light generate a phase shift angle of 0 °, and the lens layer 131 is a flat mirror.

When the lens layer 131 is in the condensing lens state, the lens layer 131 makes incident ambient light generate a certain phase shift angle, so that the incident ambient light is converged, and the converged ambient light is transmitted to the second photoelectric conversion unit 102.

The lens layer 102 in the condensing lens state or the flat lens may be switched by receiving different voltages or different mechanical pressures.

Specifically, the lens layer 131 controlled in the condensing lens state by applying different voltages or the planar lens may be: when a first voltage is applied to the lens layer 131, the refractive index of the lens layer 131 under the control of the first voltage is such that the incident light does not generate phase shift, and is in a planar lens state, i.e. a super-planar lensThe phase shift angle generated for the incident ambient light is 0 °; when a second voltage is applied to the lens layer 131, the refractive index of the lens layer 131 under the control of the first voltage causes a certain phase shift of the incident light, i.e. the phase shift angle of the super-planar lens generated for the incident ambient light is

Wherein the content of the first and second substances,

and if the optical power is larger than 0, the hyperplane lens is a condensing lens.

Further, when the control module 100 receives a second instruction to control the first area A1 to be in the image display state, the first photoelectric conversion unit 101 emits light to display an image, the lens layer 131 is in the flat lens state, and the second photoelectric conversion unit 102 stops converting the ambient light into the electrical signal.

When control module 100 receives first instruction and is in the image acquisition state in order to control first region A1, first photoelectric conversion unit 101 stops the outgoing light, and lens layer 131 is in the condensing lens state, and will ambient light assemble transmit to second photoelectric conversion unit 102, and second photoelectric conversion unit 102 receives and gathers from the lens layer provides through after assembling ambient light, and will ambient light converts the signal of telecommunication into.

In this embodiment, the first photoelectric conversion unit 101 and the first readout circuit 121 are disposed opposite to each other in the vertical direction, and meanwhile, the first photoelectric conversion unit 101 and the first readout circuit 121 on the lower side of the second photoelectric conversion unit 102 are disposed on the same layer, and the lens layer 131 is located right above the layer structure where the second photoelectric conversion unit 102 is located.

In this embodiment, the first conversion unit 101 is an LED, an OLED or a μ -LED, and the second conversion unit 102 is a PD.

Referring to fig. 12-13, fig. 12 is a schematic diagram illustrating a specific structure of the lens layer 131 shown in fig. 11, and fig. 13 is a schematic diagram illustrating an optical path structure when the lens layer 131 is in a condenser state.

As shown in fig. 12, the lens layer 131 is a hyperplane lens (metaplanar lens), and the hyperplane lens in the lens layer 131 includes a plurality of unit structures U, and any desired phase distribution can be accurately obtained by adjusting the size and arrangement of each unit structure U.

Specifically, as shown in fig. 13, the phase distribution required for the hyperplane lens satisfies the formula (1) according to the optical path difference requirement required to reach the lens focal point f:

in the formula (1), the center point of the lens is used as the origin of the coordinate system, (x, y) are the coordinates of a certain position on the lens, f is the focal length,

to phase, λ is the wavelength of the incident light.

The wavelength λ of the super-planar lens can be controlled by applying different voltages externally or by mechanical means, and the dynamic adjustment of the focal length of the lens layer 131 can be realized by adjusting the phase of the super-planar lens according to the formula.

The phase of the hyperplane lens is adjusted by loading different voltages, namely, the phase shift of incident light is controlled by adjusting the refractive index in the microstructure through different voltages, so that the focal length is changed.

Specifically, when light waves are transmitted in a medium, the transmission speed is lower than the free space wave velocity and is changed into c/n, wherein c is the free space wave velocity, and n is the refractive index of the medium. Under the condition of the same transmission distance, the refractive indexes of the materials are different, the time for delaying the optical wave is different, and the generated phase difference is different.

For example, as shown in fig. 12, the equivalent refractive index of the structural unit of the hyperplane lens can be modulated by a micro varactor or other active devices. In a medium with non-uniform refractive index, the change of adjacent refractive indexes of light waves is delta n, and the phase difference generated by the transmission d length is formula (2):

in the formula (2), λ is a free space wavelength.

In other embodiments of the present application, the phase adjustment of the super-planar lens through the mechanical structure includes using a transparent elastic material as a substrate, adjusting different stretching degrees of the elastic film by loading different voltages, and changing the shape of the lens and the period size of the super-surface array during stretching, so that the phase of the super-surface is redistributed, thereby changing the focal length f.

It can be seen that the focal length f of the lens layer 131 can be adjusted in real time according to the requirements of the pixels of the acquired image, so that the definition and quality of the image acquired by the image acquisition module 13 can be ensured.

Referring to fig. 14-15, fig. 14 is a schematic diagram of an optical path of the lens layer in the plane mirror mode shown in fig. 13, and fig. 15 is a schematic diagram of an optical path of the lens layer in the collecting mirror mode shown in fig. 13.

As shown in fig. 14, the hyperplane lens in the mirror sheet 131 makes the phase shift angle of the incident ambient light be 0 °, and the mirror sheet 131 is a plane mirror. At this time, the light emitted from the first photoelectric conversion unit 101 is emitted from the lens layer to the outside of the display panel 11, that is, from the light emitting surface to the external environment. Since the super-plane mirror is a plane mirror, it can be ensured that the light inside the display panel 10 can be accurately emitted from the mirror layer 131 and the light-emitting surface, and abnormal phenomena such as distortion of the light emitted from the first photoelectric conversion unit 101 serving as the sub-Pixel for performing image display will not occur.

As shown in FIG. 15, the hyperplane lens in the lens layer 131 makes the phase shift angle of the incident ambient light be
