The invention relates to a low-power-consumption color changing wall unit comprising an
infrared remote controller, an
infrared receiving and decoding circuit, a
peripheral interface controller (PIC) singlechip, a power generator, an
liquid crystal display (LCD) screen drive circuit and a
liquid crystal unit, wherein the
infrared receiving and decoding circuit, the PIC singlechip, the power generator, the LCD screen drive circuit and the
liquid crystal unit are collected in sequence; the infrared receiving and decoding circuit communicates with the infrared remote controller; the liquid
crystal unit comprises anti-dazzle glass, a blue LCD screen and a brown LCD screen painted with black
printing ink at the back, which are arranged in sequence so as to overlap into seven colors; the blue LCD screen and the brown LCD screen are multi-steady-state LCD screens; the infrared receiving and decoding circuit, the PIC singlechip, the power generator and the LCD screen drive circuit are arranged on a back plate; and the liquid
crystal unit and the back plate are arranged from top to bottom, and are sealed by frames. Compared with the prior art, the low-power-consumption color changing wall unit provided by the invention has the beneficial effects of integrating multiple techniques, such as infrared
remote control and multi-stead-state liquid
crystal and the like into a whole, and havingthe advantages of
energy conservation,
environmental protection, beautiful decoration, as well as flexibility and convenience for operation and the like.
