Full screen optical components and electronic equipment

Abstract

The invention provides a full-screen optical assembly, which is used in electronic equipment. The electronic equipment includes a display screen, and the optical assembly includes: a backlight module, an active light sensor, and a dimming member. On both sides, the backlight module includes a first prism film and a second prism film laminated on the first prism film, the first prism film includes several first triangular prisms, and the second prism film includes several second triangular prisms , the major axis of the first triangular prism and the major axis of the second triangular prism are perpendicular to each other; the first triangular prism comprises a first incident surface, the second triangular prism comprises a second incident surface, and the display surface , the first light incident surface and the second light incident surface are arranged parallel to each other, the active light sensor includes a sensor and a light emitter, and the dimmer is used to make the light emitted by the light emitter incident at an incident angle that is inclined compared with the vertical direction After reaching the first light incident surface, it is emitted from the second light exit surface, so that the light passes through the display screen at a vertical angle.

Description

technical field [0001] The invention relates to the technical field of terminals, in particular to a full-screen optical component and electronic equipment. Background technique [0002] Active optical devices play a very important role in smart electronic devices such as mobile phones and tablet computers. When these devices work, they will actively emit light beams and realize specific functions according to the light signals reflected by surrounding objects, such as proximity light sensors. In order to avoid being noticed by users, these devices emit signals in the infrared band, and in order to ensure the optical path of the device, opening holes in the mobile phone casing is a conventional method. [0003] The screen-to-body ratio of the current terminal has become the core of various manufacturers. In the existing technology, in order to achieve a large display screen, the screen of the mobile phone is cut in a special shape, leaving a notch-shaped frame for these part...
