The embodiment of the invention discloses an electric control film and electronic equipment. The electric control film comprises a transparent substrate layer, a transparent conductive layer, a polymer dispersed liquid crystal layer, a power supply device and a controller, wherein the transparent conductive layer is attached to the transparent substrate layer; the polymer dispersed liquid crystal layer is arranged in the transparent conductive layer, wherein the birefringence coefficient of liquid crystal in the polymer dispersed liquid crystal layer is larger than or equal to a target coefficient threshold value; the power supply device is connected with the transparent conductive layer; and the controller is connected with the power supply device and used for controlling the power supply device to provide power supply voltage for the polymer dispersed liquid crystal layer through the transparent conductive layer so as to control deflection of liquid crystals in the polymer dispersed liquid crystal layer.
Description
Technical field [0001] The present application embodiment relates to the field of liquid crystal technology, and is, but is not limited to, an electronically controlled film and an electronic device. Background technique [0002] With the more and more extensive mobile phone use, the privacy of mobile phone reading is more concerned. Users want to block the voyeurce of the outside world when reading some content involving personal privacy, but does not affect the display effect during normal use. In the relevant technique, the anti-inflation membrane technology problem is unable to achieve anti-peep mode and normal mode switching, and affecting the normal display effect. Inventive content [0003] In view of this, an embodiment of the present application provides an electronically controlled film and an electronic device. [0004] The technical solution of the present application example is achieved: [0005] In the first aspect, the present application provides an electronicall...
