Abstract: A full-screen optical component, applied to an electronic device comprising a display screen, comprising a backlight module, an active light sensor including a sensor and a light emitter, and a dimmer. The display screen and the active light sensor are located on two opposite sides of the backlight module. The backlight module includes a first prism film and a second prism film stacked on the first prism film. The first prism film includes several first prisms. The second prism film includes several second prisms. The first prism includes a first in-light surface, and the second prism includes a second in-light surface. A display surface of the display screen, the first in-light surface, and the second in-light surface are disposed in parallel. The dimmer is configured to direct light emitted by the light emitter to the first in-light surface at an incident angle that is inclined relative to a vertical direction.
