Huawei Technologies Co., Ltd. has applied for a patent. It is titled ‘Structure, Camera Module and Terminal Equipment for Hidden Front Camera’ on March 18, 2019. In other words, this is Huawei’s approach for an under-screen camera.
The patent abstract states that the utility model provides a structure for hiding a front camera, a camera module, and a terminal device. The structure includes a light guide plate that is located between the front camera and the cover glass. There is also the projection of the light guide. It covers the projection of the notch in the direction perpendicular to the display screen. In addition, it also includes one or more color light sources located on the side of the light guide plate. They are used to emit light of specified color to the side of the light guide plate under the control of the processor. The light guide plate is also used to change the propagation direction of the light of the specified color to be perpendicular to the display. So the light guide plate displays the specified color.
Through the cooperation of the provided light guide plate and the color light source, the light emitted by the color light source is refracted and emitted into the gap blocked by the light guide plate. Thereby, it blocks the gap and improves the display effect of the terminal device.
From the above description, this patent should be a solution for an under-screen camera.
