Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 7, fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the present invention, and as shown in fig. 1 to 7, the electronic device includes:

the display device comprises a control chip, a display screen 10 and a camera module 20, wherein the control chip is electrically connected with the display screen 10, the display screen 10 comprises a first display area 11 and a second display area 12, the first display area 11 comprises M pixels, the second display area 12 comprises N pixels, M is an integer larger than 2, N is an integer larger than M, and the camera module 20 is arranged corresponding to the first display area 11;

the display screen 10 has a first state and a second state, and in the first state, the control chip controls the pixels in the first display area 11 and the second display area 12 to display; in the second state, the control chip controls the pixels in the first display area 11 to stop displaying, and controls the pixels in the second display area 12 to display, so that the external light can irradiate into the camera module 20 through the first display area 11.

It should be noted that, in the embodiment of the present invention, the display screen 10 may be controlled by the control chip to have the first state and the second state.

The working principle of the embodiment of the invention can be expressed as follows:

in the first state, when the display screen 10 can be used to display target content (which may include text information, image information, or video information, etc.), and the camera module 20 does not need to operate at this time, both the pixels in the first display area 11 and the pixels in the second display area 12 on the display screen 10 can be used to display the target content. Thus, the display area of the display screen 10 is increased, and the display effect is enhanced. In addition, when the second state, camera module 20 needs work (need to gather image information or video information) this moment, then control the pixel in the first display area 11 and stop showing, make external light can shine to camera module 20 in seeing through first display area 11, thereby accomplish the collection of image information or video information, the image information or the video information that camera module 20 gathered can be shown in real time to the pixel in the second display area 12 simultaneously, convenience of customers previews the image information or the video information of gathering.

Wherein the area of the first display region 11 is smaller than the area of the second display region 12. In addition, a gap is formed between two adjacent pixels in the first display region 11, and the gap allows light to pass through. It should be noted that, because micron-sized small holes exist between metal traces (which can be used for connecting each pixel) in the display screen 10, strong diffraction phenomenon is likely to occur when light passes through the micron-sized small holes. In this embodiment, the number of pixels in the first display area 11 is smaller than the number of pixels in the second display area 12, so that the number of metal wires is reduced, the number of micron-sized holes is reduced, and the occurrence of diffraction phenomenon is reduced. The definition of image information or video information collected by the camera module 20 is improved. Simultaneously, when reducing the quantity of metal wiring, can also increase the size in clearance between the two adjacent pixels, increased the area that light can follow the region that sees through in the first display area 11 promptly, increased the quantity that sees through of light to further reinforcing camera module 20 gathers image information or video information's definition.

The pixels in the first display region 11 may include three pixels of red, green and blue, so that the three pixels may constitute three primary colors, and various colors may be displayed by cooperation of the three pixels. It should be noted that the three pixels can be distributed in the first display area 11 in an array manner. For example: the pixels in the first display area 11 may be distributed as shown in fig. 3 and 4, wherein the diamonds in fig. 3 and 4 are used to represent the pixels.

In addition, in the second state, when light passes through the first display region 11, in order to reduce the occurrence of the phenomenon that light is projected into the second display region 12, that is, in order to reduce the occurrence of the crosstalk phenomenon, a portion of pixels in the second display region 12, which are connected to the first display region 11, may be controlled to stop displaying. For example: referring to fig. 1 and 2, the second display region 12 may be disposed around the first display region 11. Referring also to fig. 2, when in the second state, the second display region 12 is connected to the first display region 11, and pixels in a target region surrounding the first display region 11 (i.e., a ring-shaped region surrounding the first display region 11 in fig. 2) may stop displaying, thereby reducing the occurrence of a cross-talk phenomenon.

The positional relationship between the first display region 11 and the second display region 12 is not limited herein. For example: the first display area 11 may be located at a first edge of the display screen 10, and preferably, may be located at a middle position of the first edge, or an end position of the first edge; and the second display area 12 may be a display area on the display screen 10 other than the first display area 11. Of course, the second display area 12 may also be arranged around the first display area 11.

In the embodiment of the present invention, in the first state, the pixels in the first display area 11 and the second display area 12 can be used for displaying, and in the second state, the pixels in the first display area 11 stop displaying, and the external light irradiates the camera module 20 through the first display area 11, so that the camera module 20 finishes image or video information acquisition. Like this, under the prerequisite of guaranteeing that camera module 20 can accomplish image or video information and gather for first display area 11 and second display area 12 on the display screen 10 can all be used for showing, have increased the display area of display screen 10, thereby have strengthened the display effect of display screen 10.

Optionally, a pixel ratio in the first display region 11 is smaller than a pixel ratio in the second display region 12, where the pixel ratio is a ratio of the number of pixels to an area of the display region.

The pixel ratio may also be referred to as a pixel density. For example: the pixel ratio in the second display region 12 may be 100-200, and the pixel ratio in the first display region 11 may be 25-50. Of course, the specific value of the pixel ratio in the first display region 11 and the second display region 12 is not limited herein.

In the embodiment of the present invention, since the pixel ratio in the first display area 11 is smaller than the pixel ratio in the second display area 12, that is, the pixel density in the first display area 11 is smaller, the gap between two adjacent pixels in the first display area 11 is larger than the gap between two adjacent pixels in the second display area 12, so that the transmission effect in the first display area 11 is better, and the shooting effect of the camera module 20 is further enhanced.
