[0059] The light control module and the light control glass of the present application will be described in detail below in combination with the accompanying drawings and specific embodiments.

[0060] Please refer to FIG. 1 and FIG. 2, FIG. 1 is a cross-sectional structure diagram of a first embodiment of a dimming module provided by the present application, and FIG. 2 is a partial top view structure diagram of a first dimming unit in FIG. 1. Referring to FIG. 1, the dimming module 100 includes a first substrate 10, a second substrate 20, and a first dimming unit 30 and a second dimming unit 40 arranged between the first substrate 10 and the second substrate 20. The second substrate 20 is arranged opposite to the first substrate 10. Optionally, the first substrate 10 and the second substrate 20 both include a hard substrate such as a glass substrate.

[0061] The first dimming unit 30 includes a first electrode 31, a second electrode 32, and a first dimming medium layer 33. Optionally, the first dimming medium layer 33 is arranged between the first electrode 31 and the second electrode 32, and the material of the first dimming medium layer 33 includes dye liquid crystal or the like. The first dimming medium layer 33 is configured to adjust light transmittance according to an electric field generated by the first electrode 31 and the second electrode 32. For example, a common voltage is applied to the first electrode 31, and a maximum gray scale voltage is applied to the second electrode 32, a strong vertical electric field is formed between the first electrode 31 and the second electrode 32, and the liquid crystal molecules in the first dimming medium layer 33 are greatly deflected in the vertical direction and assume a standing posture, so that the first dimming unit 30 is in a light-transmitting state, i.e., a bright state; when no voltage is applied to the first electrode 31 and / or the second electrode 32, no electric field is formed between the first electrode 31 and the second electrode 32 to deflect the liquid crystal molecules in the first dimming medium layer 33, at this time, the liquid crystal molecules in the first dimming medium layer 33 are in an initial state, which is a light-blocking state, i.e., a dark state. Of course, the first dimming unit 30 is in the bright state or the dark state by applying or not applying a voltage, which can be set according to actual needs, and is not limited to the examples given in the present embodiment. The materials of the first electrode 31 and the second electrode 32 both include transparent conductive materials such as indium tin oxide (ITO).

[0062] The second light-adjusting unit 40 comprises a third electrode 41, a fourth electrode 42 and a second light-adjusting medium layer 43. Optionally, the second light-adjusting medium layer 43 is arranged between the third electrode 41 and the fourth electrode 42, and the material of the second light-adjusting medium layer 43 is different from the material of the first light-adjusting medium layer 33, for example, the material of the second light-adjusting medium layer 43 comprises polymer dispersed liquid crystal and the like. The second light-adjusting medium layer 43 is configured to adjust the haze according to the electric field generated by the third electrode 41 and the fourth electrode 42. For example, a voltage with a large pressure difference is applied to the third electrode 41 and the fourth electrode 42, a strong vertical electric field is formed between the third electrode 41 and the fourth electrode 42, and the liquid crystal molecules of the second light-adjusting medium layer 43 between the third electrode 41 and the fourth electrode 42 are in a transparent state; when no voltage is applied to the third electrode 41 and the fourth electrode 42, there is no vertical electric field between the third electrode 41 and the fourth electrode 42, and the liquid crystal molecules of the second light-adjusting medium layer 43 between the third electrode 41 and the fourth electrode 42 are in a haze state. Of course, whether the second light-adjusting unit 40 is in a transparent state or a haze state is determined by whether a voltage is applied or not, which can be set according to actual needs and is not limited to the examples given in the embodiment. The materials of the third electrode 41 and the fourth electrode 42 both comprise transparent conductive materials such as indium tin oxide (ITO) and the like. The material of the second light-adjusting medium layer 43 comprises polymer dispersed liquid crystal (PDLC) and the like.

Further, through the first light-adjusting unit 30 and the second light-adjusting unit 40 between the first substrate 10 and the second substrate 20, the first light-adjusting unit 30 can achieve the purpose of adjusting the light transmittance, and the second light-adjusting unit 40 can achieve the purpose of adjusting the haze, so that the light-adjusting module 100 can adjust the light transmittance and the haze at the same time, thereby solving the technical problem that the existing light-adjusting glass cannot simultaneously achieve continuous light adjustment and privacy protection.

[0064] Optionally, in the direction perpendicular to the plane where the first substrate 10 is located, the first light-adjusting unit 30 is located on the side of the second light-adjusting unit 40 close to the first substrate 10 or on the side of the second light-adjusting unit 40 far away from the first substrate 10. That is, when the first light-adjusting unit 30 and the second light-adjusting unit 40 are arranged in a stacked manner, the positions of the first light-adjusting unit 30 and the second light-adjusting unit 40 can be interchanged.

The material of the spacer layer 50 includes transparent materials such as polyethylene terephthalate (PET), polyimide (PI), polyvinyl butyral (PVB), ultra thin glass (UTG), etc.

[0070] Specifically, referring to FIG. 3 and FIG. 4, the second light-adjusting medium layer 43 is divided into a plurality of second light-adjusting medium portions 431 by the second spacer pattern 44. The second spacer pattern 44 comprises a plurality of second spacer portions 441 arranged at intervals, and a gap is formed between two adjacent second spacer portions 441. The second light-adjusting medium portion 431 is defined in the gap, so as to limit the flow of liquid crystal molecules in the second light-adjusting medium portion 431, and improve the uniformity of the cell gap. Moreover, the longitudinal cross-sectional shape of the second spacer portion 441 is trapezoidal, and the surface shape is long strip-shaped, so as to increase the area ratio of the second spacer portion 441 in the second light-adjusting medium layer 43, thereby better maintaining the cell gap of the liquid crystal cell, further improving the uniformity of the cell gap of the liquid crystal cell, and achieving the purpose of uniform light adjustment. For other descriptions, please refer to the above embodiments, which will not be repeated here.

[0071] In one embodiment, referring to FIG. 5 and FIG. 6, FIG. 5 is a cross-sectional structure schematic diagram of a third embodiment of the light-adjusting module 100 provided by the present application, and FIG. 6 is a partial top view structure schematic diagram of the first light-adjusting unit 30 in FIG. 5. Different from FIG. 3 and FIG. 4 in the above-mentioned second embodiment, the first light-adjusting medium layer 33 comprises a plurality of first light-adjusting medium portions 331 arranged at intervals, and each first light-adjusting medium portion 331 is located in the gap between two adjacent first spacer portions 341. The second light-adjusting medium portion 431 is arranged in a staggered manner with the first light-adjusting medium portion 331.

[0072] Specifically, referring to FIG. 5 and FIG. 6, the first light-adjusting medium layer 33 is divided into a plurality of first light-adjusting medium portions 331 by the first spacer pattern 34. The first spacer pattern 34 comprises a plurality of first spacer portions 341 arranged at intervals, and a gap is formed between two adjacent first spacer portions 341. The first light-adjusting medium portion 331 is defined in the gap, so as to limit the flow of liquid crystal molecules in the first light-adjusting medium portion 331, and improve the uniformity of the cell gap. Moreover, the longitudinal cross-sectional shape of the first spacer portion 341 is trapezoidal, and the surface shape is long strip-shaped, so as to increase the area ratio of the first spacer portion 341 in the first light-adjusting medium layer 33, thereby better maintaining the cell gap of the liquid crystal cell, further improving the uniformity of the cell gap of the liquid crystal cell, and achieving the purpose of uniform light adjustment.

[0073] The second light-adjusting medium layer 43 is divided into a plurality of second light-adjusting medium parts 431 by the second spacer pattern 44. The second spacer pattern 44 comprises a plurality of second spacer parts 441 arranged at intervals, and a gap is arranged between two adjacent second spacer parts 441. The second light-adjusting medium part 431 is arranged in the gap, so as to limit the flow of liquid crystal molecules in the second light-adjusting medium part 431, and improve the uniformity of the cell gap. In addition, the longitudinal section of the second spacer part 441 is in the shape of a trapezoid, and the surface shape is in the shape of a long strip. The area ratio of the second spacer part 441 in the second light-adjusting medium layer 43 is increased, so as to better maintain the cell gap of the liquid crystal cell, further improve the uniformity of the cell gap of the liquid crystal cell, and achieve the purpose of uniform light adjustment.
