Polymer liquid crystal dimming box, manufacturing method thereof, and display module

A method for manufacturing a polymer liquid crystal dimming box, comprising steps of:

• forming a first motherboard and a second motherboard, and forming a light-shielding structure on the first motherboard or the second motherboard;
• pairing the first motherboard and the second motherboard;
• forming a frame adhesive layer between the first motherboard and the second motherboard by coating;
• forming a polymer liquid crystal layer between the first motherboard and the second motherboard by dripping polymer liquid crystals, and the polymer liquid crystal layer being formed on one side of the light-shielding structure away from the frame adhesive layer;
• curing the frame adhesive layer by ultraviolet irradiation;
• curing the polymer liquid crystal layer;
• and
• cutting the first motherboard and the second motherboard after they are paired along a cutting line to form a plurality of polymer liquid crystal dimming boxes, and
• wherein opposite side surfaces of the light-shielding structure in a stacking direction of the first motherboard and the second motherboard are in contact with the first motherboard and the second motherboard, respectively, and wherein there are gaps between the light-shielding structure and the frame adhesive layer.

A display module, comprising:

• a display panel;
• and
• a polymer liquid crystal dimming box disposed on a light-emitting side of the display panel;
• wherein the polymer liquid crystal dimming box comprises:
• a first substrate;
• a second substrate disposed opposite to the first substrate;
• a polymer liquid crystal layer disposed between the first substrate and the second substrate;
• a frame adhesive layer disposed between the first substrate and the second substrate;
• and
• a light-shielding structure disposed between the frame adhesive layer and the polymer liquid crystal layer and surrounding the polymer liquid crystal layer, and
• wherein opposite side surfaces of the light-shielding structure in a stacking direction of the first substrate and the second substrate are in contact with the first substrate and the second substrate, respectively, and wherein there are gaps between the light-shielding structure and the frame adhesive layer.
