The invention discloses an automobile backdrop automatic dimming system based on a polymer dispersed liquid crystal technology and a control method of the automobile backdrop automatic dimming system, and belongs to the technical field of automobile backdrop control. The automobile backdrop automatic dimming system comprises automobile backdrop glass with a double-layer glass interlayer and a hybrid heat insulation covering film attached to the outer side of the automobile backdrop glass. A PDLC diaphragm is arranged in a double-layer glass interlayer of the automobile backdrop glass, the PDLC diaphragm is electrically connected with the MCU micro-control unit, and the MCU micro-control unit is electrically connected with the light sensor. According to the automobile backdrop automatic dimming system based on the polymer dispersed liquid crystal technology and the control method of the automobile backdrop automatic dimming system, compared with a traditional automobile backdrop, the arrangement mode of liquid crystal molecules is changed by adjusting the surrounding electric field value of the liquid crystal molecules of the PDLC diaphragm, then the glass transmittance is changed, the reaction speed is high, the working voltage is low, and the light transmittance adjusting range is large so that the system is more stable and reliable and is simpler to operate.

    本发明公开了一种基于聚合物分散液晶技术的汽车天幕自动调光系统及其控制方法,属于汽车天幕控制技术领域,包括具有双层玻璃夹层的汽车天幕玻璃以及贴合在其外侧的杂化隔热覆膜,其特征在于,所述汽车天幕玻璃的双层玻璃夹层内设置有PDLC膜片,所述PDLC膜片与MCU微控制单元电性连接,所述MCU微控制单元与光线传感器电性连接。本发明提供了一种基于聚合物分散液晶技术的汽车天幕自动调光系统及其控制方法,相较于传统汽车天幕,通过调节PDLC膜片的液晶分子周围电场值进而改变液晶分子排列方式进而改变玻璃透光度,反应速度快,工作电压低,透光度调节范围大,从而更加稳定可靠,操作更加简洁。
