In the related art, in order to facilitate the installation of the front camera 30, a mounting hole for avoiding the camera 30 is provided on the display screen 10, the camera 30 is installed in the mounting hole or the camera 30 is located on a side of the display screen 10 away from the cover plate 20 and opposite to the mounting hole, light is refracted for the first time when the light propagates from the air into the cover plate 20, since the refractive index of the cover plate 20 is greater than that of the air, the refraction angle at this time is smaller than the incident angle, and then the light further propagates from the cover plate 20 into the air medium located in the air space between the cover plate 20 and the lens of the camera 30, that is, the light propagates from the optically dense medium to the optically sparse medium, and refraction for the second time occurs, the refraction angle at this time is greater than the incident angle, that is, the refraction angle generated at the second time of refraction is greater than that at the first time of refraction, which easily causes the light to be dispersed, the light is outside the field angle of the camera 30, which is not conducive to the camera 30 capturing images. In order to facilitate more light rays to be located in the field angle area, which does not affect the image acquisition of the camera 30, the mounting holes are generally set to be larger, and the windowing size of the ink layer on the cover plate 20 is also larger.

Therefore, when the light travels from the air into the cover plate 20, the first refraction occurs, and the refraction angle is smaller than the incident angle, and then the light further travels from the cover plate 20 to the optical cement 50, and the second refraction occurs, because the refractive index of the optical cement 50 is greater than that of the cover plate 20, and the refraction angle is smaller than the incident angle, that is, the refraction angle generated during the second refraction is smaller than the refraction angle generated during the first refraction, the light further travels from the optical cement 50 to the lens 40, and the third refraction occurs, because the refractive index of the lens 40 is greater than that of the optical cement 50, and the refraction angle is smaller than the incident angle, that is, the refraction angle generated during the third refraction is smaller than the refraction angle generated during the second refraction, which is favorable for further achieving the converging effect of the light, is favorable for the light to travel to the lens of the camera 30, and is favorable for the camera 30 to collect image information, the size of the camera hole 101 is reduced, and the size of the intersection circle of the field angle of the camera 30 and the cover plate 20 is reduced to reduce the size of the ink hole on the cover plate 20 for the camera 30, thereby facilitating the full screen design of the electronic device 100.
