Referring to fig. 1 to 3, a light collecting plate 100 provided in the present application will now be described. The light-condensing panel 100 includes a plurality of dimming units 10, the dimming units 10 are arranged in an array, each dimming unit 10 constitutes a light-condensing pixel on the light-condensing panel 100, and the structure is convenient for layout.

Each light modulating cell 10 comprises a cavity 11, at least two ends of the cavity 11 are transparent, and light can pass through the cavity 11, i.e. light can enter from one end of the cavity 11 and can exit from the other end. The cavity 11 is filled with a first light-transmissive liquid 114 and a second light-transmissive liquid 115. The first light-transmissive liquid 114 and the second light-transmissive liquid 115 are immiscible with each other, i.e., the first light-transmissive liquid 114 is insoluble in the second light-transmissive liquid 115, and the second light-transmissive liquid 115 is insoluble in the first light-transmissive liquid 114, so that an interface 116 is formed between the first light-transmissive liquid 114 and the second light-transmissive liquid 115. The first transparent liquid 114 is a conductive liquid, the second transparent liquid 115 is a non-conductive liquid, and the first transparent liquid 114 and the second transparent liquid 115 are respectively located at two ends of the cavity 11, so that light rays are refracted when passing through an interface 116 between the first transparent liquid 114 and the second transparent liquid 115. One end of the cavity 11 close to the second light-transmitting liquid 115 is provided with a common electrode layer 13, the side of the cavity 11 is provided with adjusting electrodes 12, each adjusting electrode 12 is insulated from the common electrode layer 13, and the common electrode layer 13 is a light-transmitting layer.

Referring to fig. 2 and 3, for convenience of description, two sides of the cavity 11 are defined as a first side 117 and a second side 118, respectively. In this embodiment, the two sides of the cavity 11 are respectively provided with the adjusting electrodes 12, and the adjusting electrodes 12 on the two sides of the cavity 11 are respectively a first electrode 121 and a second electrode 122. Voltages are applied to the adjustment electrodes 12 on both sides of the cavity 11, and the voltages applied to the adjustment electrodes 12 are all voltages relative to the common electrode layer 13, that is, a voltage V1 is applied between the first electrode 121 and the common electrode layer 13, and a voltage V2 is applied between the second electrode 122 and the common electrode layer 13.

When V1 is equal to V2 is equal to 0, the interface 116 between the first transparent liquid 114 and the second transparent liquid 115 is planar.

When V1 is equal to V2, and V1 and V2 are both greater than zero, since the first transparent liquid 114 is a conductive liquid, the first transparent liquid 114 gathers toward each of the adjustment electrodes 12, that is, the first transparent liquid 114 gathers toward the first electrode 121 and the second electrode 122, an interface 116 is formed between the first transparent liquid 114 and the second transparent liquid 115, the middle of the interface 116 is a curved surface that is convex in a direction away from the common electrode layer 13, and positions of the interface 116 closer to each of the adjustment electrodes 12 are more inclined in a direction closer to the common electrode layer 13, so that light passing through the interface 116 is deflected.

When V1> V2, since the first transparent liquid 114 is a conductive liquid, the first transparent liquid 114 can adjust the concentration of the electrodes 12, an interface 116 is formed between the first transparent liquid 114 and the second transparent liquid 115, the middle of the interface 116 faces a convex curved surface away from the common electrode layer 13, and the position of the interface 116 closer to each adjustment electrode 12 is inclined toward the direction closer to the common electrode layer 13. And the electric field strength at the first electrode 121 will be greater than the electric field strength at the second electrode 122, more of the first light-transmissive liquid 114 will be collected at the first side 117 of the cavity 11 than at the second side 118 of the cavity 11, so that the distance from the position of the interface 116 near the first side 117 of the cavity 11 to the common electrode layer 13 will be less than the distance from the position of the interface 116 near the second side 118 of the cavity 11 to the common electrode layer 13, and light passing through the interface 116 can also be deflected.

When a voltage V1 is applied between the adjustment electrode 12 and the common electrode layer 13 on only one side of the cavity 11, that is, when a voltage V1 is applied between the first electrode 121 and the common electrode layer 13, the first transparent liquid 114 gathers to one side of the first electrode 121, so that the interface 116 formed between the first transparent liquid 114 and the second transparent liquid 115 is inclined, and the distance from one side of the interface 116 close to the first electrode 121 to the common electrode layer 13 is smaller than the distance from the other side of the interface 116 to the common electrode layer 13, so that light passing through the interface 116 is deflected; also, as V1 increases, the inclination of the interface 116 with respect to the common electrode layer 13 increases, thereby adjusting the deflection angle of the light passing through the cavity 11.

When a voltage V2 is applied between the adjustment electrode 12 and the common electrode layer 13 only on the other side of the cavity 11, that is, when a voltage V2 is applied between the second electrode 122 and the common electrode layer 13 only, the first transparent liquid 114 gathers toward one side of the second electrode 122, so that the interface 116 formed between the first transparent liquid 114 and the second transparent liquid 115 is inclined, and the distance from one side of the interface 116 close to the second electrode 122 to the common electrode layer 13 is smaller than the distance from the other side of the interface 116 to the common electrode layer 13, so that light passing through the interface 116 is deflected; also, as V2 increases, the inclination of the interface 116 with respect to the common electrode layer 13 increases, thereby adjusting the deflection angle of the light passing through the cavity 11.

A voltage V1 is applied between the first electrode 121 and the common electrode layer 13, and a voltage V2 is applied between the second electrode 122 and the common electrode layer 13, which both deflect the light rays at the interface 116 in different directions; when the first electrode 121 and the second electrode 122 are located on opposite sides of the cavity 11, the light at the interface 116 is deflected in a reverse direction. So that the deflection of the light passing through the dimming cells 10 can be controlled by applying different combined voltages between the adjustment electrodes 12 and the common electrode layer 13 of the dimming cells 10; when different combined voltages are applied between the adjustment electrodes 12 and the common electrode layer 13 of the plurality of light adjustment units 10, the light passing through the light adjustment units 10 can be converged. And the magnitude of the voltage applied to each dimming unit 10 is adjusted, so that the focusing and focusing of light can be realized.

Of course, in some embodiments, the adjusting electrode 12 may also be disposed on one side of the cavity 11, and during manufacturing, the position of the light-gathering center of the light-gathering plate 100 is determined, and the adjusting electrode 12 of each cavity 11 with an equal distance to the light-gathering center is located on one side of the corresponding cavity 11 close to the light-gathering center, so that light gathering can also be achieved.

In the light collecting panel 100 provided in the embodiment of the present application, by providing a plurality of light adjusting units 10, two ends of the cavity 11 of each light adjusting unit 10 are transparent, and the cavity 11 is filled with the first transparent liquid 114 and the second transparent liquid 115 that are immiscible, so that light is refracted when passing through the interface 116 between the first transparent liquid 114 and the second transparent liquid 115; the side edge of the cavity 11 is provided with the adjusting electrode 12, and one end of the cavity 11 is provided with the common electrode layer 13, so that a voltage is applied between the common electrode layer 13 and the adjusting electrode 12 on the side edge of the cavity 11, the first transparent liquid 114 and the second transparent liquid 115 can be deflected and inclined in the cavity 11, and light penetrating through the cavity 11 can be deflected; and the voltage between the adjusting electrode 12 and the common electrode layer 13 on the side of the cavity 11 is changed, so that the light deflection angle can be changed, and further, the light condensation can be realized through the matching of a plurality of light adjusting units 10.

In one embodiment, the cavity 11 includes a bank 111, a light-transmitting layer 112 and an insulating layer 113, where the light-transmitting layer 112 covers one end of the bank 111, and the insulating layer 113 is disposed at the other end of the bank 111. That is, the cavity 11 is surrounded by the bank 111, the transparent layer 112 and the insulating layer 113, so as to facilitate the processing. The regulating electrode 12 is arranged on the side of the cofferdam 111, namely the regulating electrode 12 is arranged on the side of the cofferdam 111, and the regulating electrode 12 is supported by the cofferdam 111. The common electrode layer 13 is provided on the insulating layer 113, and the common electrode layer 13 is supported by the insulating layer 113.

In one embodiment, referring to fig. 1, the transparent layers 112 of the dimming units 10 are integrally formed, that is, a plurality of regions are directly divided on a whole transparent sheet, and each region serves as the transparent layer 112 of the corresponding dimming unit 10, so as to facilitate processing and manufacturing.
