Here, the first substrate 2, the plurality of pixel units, and the second substrate 1 may cooperate to form a flexible organic light emitting diode display POLED.
Further description is provided below in connection with fig. 1-3. In the embodiment of the invention, the CMOS device 4 is arranged outside the display area, for example, above the display area in the illustration, of course, the CMOS device 4 is arranged at any position outside the display area, for example, at the side or below the display area, the camera lens 5 is arranged on the second substrate 1 corresponding to the CMOS device 4, so that the CMOS device 4 and the camera lens 5 cooperate to form the camera 10, and since the first substrate 2 and the second substrate 1 are flexible substrates, the CMOS device 4 is arranged behind the display area, referring to fig. 2, when in use, the folded part 6 can be folded, so that the camera 10 can be switched between the first state and the second state, and the camera 10 can be folded to the second state to serve as a rear camera under the condition that front photographing is not needed, and the display area is full-screen display. The camera 10 is in a reverse first state when front shooting is needed, and serves as a front camera, so that the camera 10 cannot influence a display area, grooving and the like are not needed, the rear cameras of the front camera can be mutually converted, and structural design space is reduced. The camera 10 can be folded to the back of the display screen when the camera is not needed, so that privacy leakage is prevented. Meanwhile, for other sensors, for example, a light sensor or the like may be provided at the bending portion 6 or around the CMOS device 4, and when the sensor needs to always face the display area, it is preferable to provide at an end of the bending member close to the display area.
