The invention is suitable for the technical field of automobiles, and discloses a vehicle-mounted display device, a peep-proof method and an automobile, the vehicle-mounted display device comprises a liquid crystal module and a backlight module, and the liquid crystal module comprises a liquid crystal display box and a first peep-proof control panel; the first peep-proof control panel comprises a first substrate and a second substrate which are oppositely arranged, a liquid crystal molecular layer is arranged between the first substrate and the second substrate, and the side, facing the second substrate, of the first substrate and the side, facing the first substrate, of the second substrate are each provided with a plurality of electrode areas; when the electrode areas receive control voltages, liquid crystal molecules of the liquid crystal molecule layer deflect, the control voltages between the electrode areas are mutually independent, and deflection angles of the liquid crystal molecules correspond to the control voltages. Partitioned peep-proof control of the vehicle-mounted display device is achieved, the requirement that the vehicle selects a proper peep-proof angle according to the viewing angle of people in the vehicle is met, and then the display effect of the vehicle-mounted display device is improved.
本申请适用于汽车技术领域,公开了一种车载显示设备、防窥方法及汽车,车载显示设备包括液晶模组和背光模组,液晶模组包括液晶显示盒和第一防窥控制面板;第一防窥控制面板包括相对设置的第一基板和第二基板,第一基板与第二基板之间设有液晶分子层,第一基板朝向第二基板的一侧和第二基板朝向第一基板的一侧均设有多个电极区域;当电极区域接收控制电压时,液晶分子层的液晶分子发生偏转,其中,每个电极区域之间的控制电压相互独立,液晶分子的偏转角度与控制电压存在对应关系。实现了车载显示设备的分区防窥控制,满足车辆根据车内人员视角选择合适的防窥视角的需求,进而提高车载显示设备的显示效果。
