Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
Embodiment one
Referring to Fig.1, a kind of structural schematic diagram of display device of the embodiment of the present invention is shown, Fig. 2 shows the present invention
A kind of cross-sectional view of display device of embodiment, Fig. 2 are display devices shown in FIG. 1 along section A-A ' cross-sectional view.
The embodiment of the invention provides a kind of display devices 10, comprising: display panel 11 and setting go out in display panel 11
At least one imaging sensor 12 of light side, display panel 11 include the array substrate 111 and color membrane substrates 112 to box setting,
Black matrix 1121 is provided on color membrane substrates 112, orthographic projection of the imaging sensor 12 on color membrane substrates 112 is located at black matrix
In region where 1121；Imaging sensor 12 is configured as when display device 10 is in self-timer mode, is carried out image and is adopted
Collection.
When user starts by touch control operation the camera programm in display device 10, and pass through touching at the interface of camera programm
When at least one imaging sensor 12 that control operation controls the display panel 11 light emission sides is worked, at this point, at display device 10
In self-timer mode, imaging sensor 12 can then carry out Image Acquisition, and the imaging sensor 12 of 11 light emission side of display panel can also
Referred to as front camera；When user closes camera programm, display device 10 is then in non-self-timer mode；In addition, away from aobvious
Show that the side of 11 light emission side of panel is also possible to be provided with rear camera, when user passes through touch control operation at the interface of camera programm
When switching to rear camera and being worked, display device 10 is also at non-self-timer mode.
When display device 10 is in non-self-timer mode, the imaging sensor 12 of 11 light emission side of display panel is set no longer
Image Acquisition is carried out, display device 10 is normally shown, and the orthographic projection due to imaging sensor 12 on color membrane substrates 112
In the region where black matrix 1121,1121 region of black matrix itself is opaque, and imaging sensor 12 also would not
Influence display panel normally goes out light, and therefore, display device 10 may be implemented to be displayed in full screen.
In addition, also do not need to be popped up as Pop-up camera when imaging sensor 12 carries out Image Acquisition, because
This, does not influence the durability of imaging sensor 12
It should be noted that display panel 11 further includes the liquid crystal being arranged between array substrate 111 and color membrane substrates 112
