Acrylic color-changing boards mainly include red white boards, blue white boards and black-and-white boards. According to different color changing needs, certain light-changing materials are added to make the finished light box show two different colors when the external light source or the built-in light source is turned on. This is called the color changing board. Currently there are black and white boards, blue white boards, green white boards and so on. The color-changing board usually has a frosted surface on one side.
Mainly used for interior lighting signs and display boards.
