Abstract

A terminal is provided, and the terminal includes a housing, a front screen, a circuit board, and a power supply. The front screen is disposed on the housing, both the circuit board and the power supply are disposed inside the housing, and the power supply is connected to the circuit board. The front screen includes a toughened glass, a color changing layer, and a display screen that are sequentially stacked. The color changing layer is connected to the circuit board, and can change a color when receiving power supply. The color changing layer is disposed in the front screen, and may change a color when receiving the power supply from the circuit board. The color changing layer is configured only to change a color and cannot display a complex image, and power consumption of the color changing layer is far less than that of the display screen.

First claim

What is claimed is:

1 . A terminal, wherein the terminal comprises a housing, a front screen, a circuit board, and a power supply, wherein
the front screen is disposed on the housing, both the circuit board and the power supply are disposed inside the housing, and the power supply is electrically connected to the circuit board; the front screen comprises a toughened glass, a color changing layer, and a display screen that are sequentially stacked; and the color changing layer is electrically connected to the circuit board, and is configured to change a color when receiving power supply from the circuit board.

2 . The terminal according to claim 1 , wherein the color changing layer is an electrochromic combination layer;
the electrochromic combination layer comprises a first transparent conducting layer, an ion storage layer, an ion conductor layer, an electrochromic layer, and a second transparent conducting layer that are sequentially stacked; and both the first transparent conducting layer and the second transparent conducting layer are electrically connected to the circuit board.

3 . The terminal according to claim 2 , wherein the front screen further comprises a silicon dioxide layer, an optical adhesive layer, and a touch control board;
the first transparent conducting layer of the electrochromic combination layer is fastened on the toughened glass; a first surface of the silicon dioxide layer is fastened on the second transparent conducting layer of the electrochromic combination layer; a second surface of the silicon dioxide layer is bonded to a first surface of the display screen by using the optical adhesive layer; and a second surface of the display screen is attached to the touch control board.

4 . The terminal according to claim 2 , wherein a thickness of the electrochromic combination layer is less than or equal to 10 micrometers.

5 . The terminal according to claim 3 , wherein a thickness of the electrochromic combination layer is less than or equal to 10 micrometers.

6 . The terminal according to claim 1 , wherein the color changing layer is a monochrome conversion liquid crystal layer;
