[0028] See also Figures 1 to 3 , an embodiment of the present invention provides a light emitting diode (OLED) array substrate, comprising:

[0029] A flexible first substrate 2 and a flexible second substrate 1 arranged opposite to each other;

[0030] A plurality of OLED pixel units 3 are provided on the surface of the first substrate 2 facing the second substrate 1, wherein the area where the plurality of OLED pixel units 3 are provided on the substrate body of the first substrate 2 forms a display area;

[0031] a complementary metal oxide semiconductor (CMOS) device 4 disposed on a surface of the first substrate 2 facing the second substrate 1 , wherein the CMOS device 4 is located in an area outside the display area;

[0032] a camera lens 5 disposed on a surface of the second substrate 1 away from the first substrate 2, wherein an orthographic projection of the camera lens 5 on the surface of the first substrate 2 coincides with the CMOS device 4;

[0033] The portion between the first substrate 2 and the second substrate 1 corresponding to the display area and the CMOS device 4 is formed as a bending portion 6. Through the bending portion 6, the camera 10 includes a first state facing the same direction as the display area and a second state facing opposite to the display area.

[0034] In this embodiment of the present invention, a flexible first substrate 2 and a second substrate 1 are provided. A display area is provided on the first substrate 2, a CMOS device 4 is provided behind the display area on the first substrate 2, and a camera lens 5 is provided on the second substrate 1. This allows the camera lens 5 and the CMOS device 4 to form a foldable camera 10 that does not affect the display area, thus achieving a full-screen display. Here, the first substrate 2, multiple pixel units, and the second substrate 1 can be combined to form a flexible organic light-emitting diode display (POLED).

[0035] The following combination Figures 1 to 3 Further explanation is given. In the embodiment of the present invention, a CMOS device 4 is provided outside the display area, for example, above the display area as shown in the figure. Of course, the CMOS device 4 can also be provided at any position outside the display area, for example, on the side or below the display area. A camera lens 5 is provided 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 a camera 10. Since the first substrate 2 and the second substrate 1 are flexible substrates, the CMOS device 4 is provided behind the display area. Figure 2 When in use, the camera 10 can be switched between the first state and the second state by folding the bending part 6. When there is no need to take front-facing photos, the camera 10 is folded to the second state and acts as a rear camera, and the display area is displayed in full screen. When front-facing photos are needed, the camera 10 is in the first state and acts as a front camera, so that the camera 10 does not affect the display area, and there is no need to dig grooves, etc. The front camera and the rear camera can be converted into each other, reducing the structural design space. Of course, it can also be applied to computers, so that when the camera 10 is not needed, it can be bent to the back of the display screen to prevent privacy leakage. At the same time, other sensors, such as light sensors, can be arranged on the bending part 6, or around the CMOS device 4. When the sensor needs to always face the direction of the display area, it is preferably arranged at the end of the bending part close to the display area.

[0036] Here, the first substrate 2 may be provided with a camera circuit connected to the CMOS device 4. In one embodiment of the present invention, the first substrate 2 may be a thin-film transistor array substrate. In this case, the camera circuit can be provided on the first substrate 2 using an OLED TFT process. That is, the thin-film transistor array substrate is provided with a connecting circuit in the area opposite the CMOS device 4, and the CMOS device 4 is connected to the connecting circuit. This configuration can effectively reduce power consumption.

[0037] Here, an organic planarization layer 7 is filled between the CMOS device 4 and the second substrate 1. The organic planarization layer 7 ensures light transmission performance.

[0038] Preferably, a light shielding layer 8 is provided at the bent portion 6 to isolate the light source in the display area from the CMOS device 4. The light shielding layer 8 can be a black light-shielding ink layer. Providing the light shielding layer 8 above the display area effectively prevents the light source from reaching the CMOS device 4, thereby preventing the pixel unit from affecting the CMOS device 4.

[0039] Here, the second substrate 1 may be made of a polyimide film CPI.

[0040] See also Figure 3 , the length of the bent portion 6 in the width direction of the display area is less than or equal to the length in the width direction of the display area.

[0041] Continue to see Figure 3 According to another aspect of the present invention, an embodiment of the present invention further provides an electronic device, including a display screen 9, wherein the display screen 9 is made of the light emitting diode OLED array substrate as described above.

[0042] Preferably, the electronic device is a mobile phone, a tablet computer, a laptop computer, a PDA, a vehicle-mounted terminal, a wearable device or a display.

[0043] In summary, the embodiment of the present invention sets a flexible first substrate 2 and a second substrate 1, sets a display area on the first substrate 2, sets a CMOS device 4 behind the display area on the first substrate 2, and sets a camera lens 5 on the second substrate 1, so that the camera 10 formed by the camera lens 5 and the CMOS device 4 can be folded without affecting the display area, thereby realizing a full screen.

[0044] In addition, the present invention may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed.
