Embodiment 1

[0031] figure 1 A schematic cross-sectional view of a display device provided by an embodiment of the present invention is shown; figure 2 A schematic structural diagram of a display panel provided by an embodiment of the present invention is shown. to combine figure 1 and figure 2 As shown, the present invention provides a display device, the display device includes: a camera 90, and the camera 90 is used for lighting and imaging. The display device further includes a display panel 10 located on the light-incident side of the camera 90 . The display panel 10 is, for example, a flexible OLED display panel 10 and has a bending or folding function.

[0032] In this embodiment, the display panel 10 includes a display portion 11 , a binding portion 13 and a bending portion 12 , and the bending portion 12 is located between the display portion 11 and the binding portion 13 . The display portion 11 of the display panel 10 is provided with a plurality of light-emitting units (n...

Embodiment 2

[0053] image 3 A schematic cross-sectional view of a display device provided by an embodiment of the present invention is shown. to combine figure 2 and image 3 As shown, Embodiment 2 of the present invention provides a display device, and the structure of the display device is similar to the display device provided in Embodiment 1 of the present invention. The same or similar parts are not repeated in this embodiment. The difference is that the second backplane 22 is located on a side of the first backplane 21 close to the display portion 11 , and the second backplane 22 is disposed corresponding to the second display area 120 . Specifically, a groove is formed on the first backplane 21 corresponding to the position of the second display area 120, and the direction of the notch of the groove faces the second display area 120 of the display part 11, and the first The two backplanes 22 are filled in the groove, so that the surface of the backplane 20 close to the display ...

Embodiment 3

[0056] Figure 4 A schematic cross-sectional view of a display device provided by an embodiment of the present invention is shown. to combine figure 2 and Figure 4 As shown, Embodiment 3 of the present invention provides a display device, and the structure of the display device is similar to the display device provided in Embodiment 2 of the present invention, and this embodiment will not describe the same or similar parts one by one. The difference is that the two surfaces of the first backplane 21 away from and close to the display part 11 are flat surfaces, and the second backplane 22 is arranged on the first backplane 21 close to the display part 11 On the surface of one side, a first adhesive layer 31 is filled between the display portion 11 and the back plate 20 , and the first adhesive layer 31 covers the second back plate 22 .

[0057] In the display device provided by the third embodiment of the present invention, since the second backplane 22 is arranged closer ...

Abstract

The invention provides a display device. The display device comprises a camera; the display panel is located on the light incident side of the camera, the display panel comprises a first display area and a second display area, and the second display area is arranged corresponding to the camera; the back plate is located between the camera and the display panel, the back plate comprises a first back plate and a second back plate, the vertical projection of the second back plate on the display panel at least covers the second display area, and the light reflectivity of the second back plate is smaller than that of the first back plate. The light reflectivity of the second back plate is smaller than that of the first back plate, so that the influence of the light emitting unit of the first display area on the lighting of the camera in the display process can be effectively avoided, and the imaging effect is effectively improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] Organic Light Emitting Diode (OLED) display device has low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing angle, wide operating temperature range, and can realize flexible display and large-area full-screen display. With many advantages such as color display, it is recognized by the industry as the display device with the most development potential. [0003] With the development of science and technology and the improvement of people's product requirements, a full screen with a higher screen-to-body ratio has become a much-anticipated development trend of smartphones. The under-screen camera technology can hide the camera under the display panel and the display panel corresponding to the camera area can still display normally, which is conducive to increasi...
