Claims

1. A variable color backlight panel, comprising: The system includes a nano-embossed layer (1), a sputtered aluminum layer (2), a PC chrome plate layer (3), a wood grain printing layer (4), and an LED backlight panel (5) connected in sequence. The nano-embossed layer (1), the sputtered aluminum layer (2), the PC chrome plate layer (3), and the wood grain printing layer (4) are all configured to be light-transmitting. In the absence of backlight, the LED backlight panel (5) exhibits a hairline metallic texture resulting from the combined action of the nano-embossed layer (1), the sputtered aluminum layer (2), the PC chrome plate layer (3), and the wood grain printing layer (4). When backlit, the LED backlight panel (5) exhibits a warm wood grain texture resulting from the combined action of the nano-embossed layer (1), sputtered aluminum layer (2), PC chrome plate layer (3), wood grain printing layer (4) and LED backlight panel (5).

2. The variable color backlight panel of claim 1, wherein, The nano-embossed layer (1) can be replaced with a light-transmitting structural layer with other nano-embossed patterns.

3. The variable color backlight panel of claim 1, wherein, The sputtered aluminum layer (2) can be replaced with a light-transmitting structural layer sputtered with other metals, such as chromium or silver.

4. The variable color backlight panel of claim 1, wherein, The PC chrome plate layer (3) can be replaced with a structural layer printed with other light-transmitting textures, such as mineral textures or water ripple textures.

5. The variable color backlight panel of claim 1, wherein, The LED backlight panel (5) is configured as an RGB variable color structure.

6. A variable color backlight panel according to claim 5, wherein, The LED backlight panel (5) has several RGB LED beads (51) installed in it. The several RGB LED beads (51) can be dimmed to match different textures. The dimming settings include adjusting the color and brightness of the light.
