Described herein are liquid crystal (LC) assemblies that are dimmable and techniques for manufacturing LC assemblies. Example LC assemblies are described that include a flexible substrate, a twisted nematic liquid crystal, a polarizer with cellulose triacetate and an ultraviolet blocker, a polycarbonate layer, polyvinyl butyral as a connecting layer, or any combination of these features. A flexible substrate can permit an LC assembly to be applied to a window or other rigid surface, even if the surface has a three-dimensional curvature. LC assemblies featuring Guest-Host or vertical alignment configurations are also described. In some embodiments, a dimmable LC assembly is provided as part of a kit including a control unit adapted to electrically connect to the LC assembly via a cable. Both the LC assembly and the control unit can be mounted to a window or other rigid surface. The control unit can be powered using a photovoltaic cell.

The present disclosure provides a display device and a splicing screen, relating to the field of display equipment. The display device includes a liquid crystal display screen, a lamp board, and a printed circuit board. The lamp board includes a flexible circuit board and a plurality of light-emitting diodes. The flexible circuit board includes a first part and a second part connected to each other. The light-emitting diodes are disposed on the first part, and the first part is disposed on an edge of a front surface of the liquid crystal display screen. The second part extends outside of the liquid crystal display screen to a rear surface of the liquid crystal display screen and is detachably plugged into the printed circuit board disposed on the rear surface. Since the first part is disposed on the edge of the front surface of the liquid crystal display, a picture displayed on the light-emitting diodes can block an edge region of the liquid crystal display screen. Therefore, when a plurality of display devices is spliced into a splicing screen, split seams can be reduced or even eliminated, thereby improving visual effect.
