Huawei Technologies filed a patent on March 18, 2019 entitled "Structure, camera module and terminal device for concealing front camera", which was announced on April 14, 2020.
The patent abstract claims that the utility model provides a structure, camera module, and terminal device for concealing a front-facing camera.
The structure comprising a light guide plate disposed between said front camera and said cover glass, and said light guide plate covering said notch in a projection perpendicular to said display direction.
It also has one or more colored light sources disposed on the side of the said light guide for emitting a specified color of light to the side of the said light guide under the control of the said processor.
Said light guide is also used to change the direction of propagation of light of said specified color to a direction perpendicular to said display, thereby allowing said light guide to display said specified color.
The light from the colored light source is refracted into the notch covered by the light guide plate and the colored light source is emitted, thus covering the notch and improving the display effect of the terminal equipment.
From the above description, this patent should be a solution for an under-screen camera.
Previously, OnePlus employees said that this year, there will definitely be manufacturers to launch products for the off-screen solution, but based on the current flagship quality requirements, it is uncertain whether manufacturers will be used on the flagship main product.
