    摘要: A smart window configured to transition between a substantially transparent state and a dimmed state. The smart window includes a first substantially transparent conductive layer; an ion storage layer on the first substantially transparent conductive layer; an electrolyte layer on a side of the ion storage layer away from the first substantially transparent conductive layer; an electrochromic layer on a side of the electrolyte layer away from the ion storage layer; a second substantially transparent conductive layer on a side of the electrochromic layer away from the electrolyte layer; and an antenna layer configured to receive wireless power transmissions to provide energy for the smart window to transition between the substantially transparent state and the dimmed state. An orthographic projection of the electrochromic layer on the first substantially transparent conductive layer substantially covers an orthographic projection of the antenna layer on the first substantially transparent conductive layer.

    摘要: A backlight assembly includes a light guide plate, containing a plurality of dots. Each dot includes a first reflecting surface and a second reflecting surface, respectively configured to reflect a first incident light such that reflected light emerges in a first preset direction in a narrow viewing angle mode, and to diffusely reflect a second incident light such that the reflected light emerges dispersedly in a wide viewing angle mode. A first light source can be disposed over a lateral side of the light guide plate and facing the first reflecting surface, to provide the first incident light on the first reflecting surface in the narrow viewing angle mode. A second light source can be disposed over another lateral side of the light guide plate and facing the second reflecting surface to provide the second incident light on the second reflecting surface in the wide viewing angle mode.
