In addition, examples of various specific processes and materials are provided herein, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

an electronic apparatus 1000 and a display control method thereof according to an embodiment of the present application are described below with reference to fig. 1 to 9.

As shown in fig. 1 and 2, an electronic device 1000 according to an embodiment of the present application may include: LCD body 1, backlight 2, light supplement source 3 and camera 200.

As shown in fig. 2, the backlight plate 2, the light supplement source 3, and the camera 200 are disposed on the back side of the LCD body 1. Here, during use of the electronic apparatus 1000, a side of the electronic apparatus 1000 facing a user is a "front side", and a side of the electronic apparatus 1000 facing away from the user is a "back side".

as shown in fig. 2, the LCD body 1 includes a predetermined region 101A, the backlight panel 2 has a through hole 20 opposite to the predetermined region 101A, the camera 200 is disposed opposite to the through hole 20 to obtain light in the external environment through the through hole 20 and the predetermined region 101A, and the light supplement source 3 is adapted to emit light to the predetermined region 101A through the through hole 20. Here, it should be noted that "the perforation 20 opposite to the preset area 101A" described herein refers to: projected in the thickness direction of the LCD body 1 (i.e., projected in the direction from the front side to the back side shown in fig. 2), the projection of the perforation 20 completely coincides with the preset region 101A; further, the "camera 200 is disposed opposite to the through hole 20" as described herein means: projected in the thickness direction of the LCD body 1 (i.e., projected in the direction from the front side to the back side shown in fig. 2), at least a part of the projection of the camera 200 is located within the preset region 101A.

That is, as shown in fig. 2 and 3, a portion of the backlight panel 2 opposite to the predetermined region 101A is hollowed out to form a through hole 20, so that the backlight panel 2 does not provide a light source for the predetermined region 101A of the LCD body 1, but the portion of the hollowed out through hole 20 may provide a light source for the predetermined region 101A through the supplementary light source 3 to light up the supplementary light source 3 when the camera 200 is not needed.

Thus, as shown in fig. 4, the electronic apparatus according to the embodiment of the present application may have the following display control method. The display control method is used for controlling the electronic equipment 1000 to at least realize a front shooting mode and a front display mode, wherein the display control method comprises the following steps: in the front display mode, the backlight plate 2 and the light supplementing source 3 are lightened; in the front image capturing mode, the backlight 2 is turned on, the light supplement source 3 is turned off, and all pixels in the preset region 101A are controlled to be turned on.

That is to say, when the electronic device 1000 executes the front display mode, the backlight plate 2 is lit, the backlight plate 2 emits light to the part (for short, the normal display region 101B) of the LCD body 1 except the preset region 101A, so that the normal display region 101B can display, the light supplement source 3 is lit at the same time, the light supplement source 3 emits light to the preset region 101A of the LCD body 1, so that the preset region 101A can display, and thus, the backlight plate 2 and the light supplement source 3 are lit at the same time, so that the whole LCD body 1 can provide light sources, so that the preset region 101A and the normal display region 101B can both display, and the LCD body 1 can display a complete picture.

When the electronic device 1000 executes the front camera shooting mode, the backlight plate 2 is still in a lighting state to continuously emit light to the normally displayed area 101B of the LCD body 1, so that the normally displayed area 101B can display, but at this time, the light supplement source 3 needs to be turned off to stop emitting light to the preset area 101A of the LCD body 1, so that the preset area 101A stops displaying, and at the same time, all pixels of the preset area 101A are controlled to be turned on, so that light in the environment on the front side of the electronic device 1000 can penetrate through the preset area 101A of the LCD body 1 and the through hole 20 to enter the camera 200 for imaging, thereby realizing the front camera shooting function.

In addition, it should be noted that "an alternative of the fill light source 3", "a relative position relationship between the fill light source 3 and the through hole 20", and "a relative position relationship between the camera 200 and the through hole 20" may be specifically selected according to actual requirements, and will be described in detail later, and will not be described herein again.

Therefore, according to the electronic device 1000 of the embodiment of the present application, the front camera mode is implemented by hiding the camera 200 at the back side of the LCD body 1, so that a hole for installing the camera 200 does not need to be formed on the LCD body 1, and the design requirement of 100% of the total screen area of the electronic device is further satisfied. In addition, the light supplement source 3 is set to supplement light for the backlight-free preset area 101A, so that the LCD body 1 can display a complete picture after the pre-shooting mode is finished.

In short, according to the electronic device 1000 of the embodiment of the present application, the camera 200 can be hidden under the screen, so as to achieve the effect of shooting under the screen, meet the design requirement of 100% of the total screen area ratio, avoid various deficiencies of the pop-up front camera in the prior art, and meet the normal display requirement of the electronic device 1000.

In some alternative embodiments of the present application, as shown in fig. 2 and 3, the complementary light source 3 may be a point light source 31 (the definition of a point light source is common general knowledge). Therefore, the light supplement source 3 is simple and small in structure and easy to arrange. Moreover, the light emitted by the point light source 31 has good divergence, and can effectively and comprehensively cover the preset area 101A, so that the preset area 101A can be well displayed in the front shooting mode and the front display mode, and the whole display effect of the LCD body 1 is improved. Here, it should be noted that, in the present application, the number and arrangement of the point light sources 31 are not limited.

Therefore, the light supplement source 3 is convenient to assemble and disassemble and lead layout. Certainly, the present application is not limited to this, in other embodiments of the present application, the height H2 of the light supplement source 3 may also be smaller than the hole depth H0 of the through hole 20, so that the light supplement source 3 may be completely accommodated in the through hole 20, thereby improving the overall structural compactness of the electronic device 1000, meeting the requirement of the light and thin development of the electronic device 1000, and being more convenient for a user to hold and use.
