Abstract:
A color-variable terminal includes a touchscreen, a display screen, a circuit board, and a liquid crystal light adjustment film. The touchscreen is located above the display screen. The circuit board is located below the display screen, and the circuit board includes a drive circuit. The liquid crystal light adjustment film is disposed on the touchscreen. The drive circuit is configured to apply a control voltage to the liquid crystal light adjustment film. The liquid crystal light adjustment film is in a transparent state when an amplitude of the control voltage is greater than or equal to a preset threshold, or the liquid crystal light adjustment film is in a non-transparent state when an amplitude of the control voltage is less than the preset threshold, and a color of the liquid crystal light adjustment film in the non-transparent state is different from a color of the display screen.
