Recently, it was reported that Huawei Technology Company Ltd. had applied for a patent, which was named “Structure, Camera Module and Terminal Equipment for Hidden Front Camera” on March 18, 2019. The announcement was made on April 14.
The patent shows that the utility model has a structure for hiding three things: a front camera, a camera module, and a terminal device. The structure also includes a light guide between the front camera and the glass screen cover.
The projection of the light guide plate is placed in the direction perpendicular to the display, which also includes the shielding of the notch and the orientation perpendicular to the display.
Moreover, it also includes one or more color light sources, which are located on the side of the light guide plate and will be 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 will also be used to change the propagation direction of the light of the specified color, which will be perpendicular to the display screen direction so the light guide plate will be able to display the specified color.
With the help of the light guide plate and the color light source, the light emitted by the color light source will be refracted and excreted into the gap blocked by the light guide plate. This prevents distance and improves the display effect of the terminal device. This patent can be a solution for manufacturing a mobile phone with an in-display camera.
A plus employee reported that different manufacturers will launch various types of equipment under the display in 2020. However, based on the quality requirements of the current flagship phones, it is still not confirmed whether the manufacturer will use it on the flagship phone of a flagship series.
