Fig. 1 is a schematic structural diagram of an electronic device 100 shown according to an exemplary embodiment, and fig. 2 is a schematic cross-sectional diagram of the electronic device 100 shown according to an exemplary embodiment. As shown in fig. 1 and fig. 2, the electronic device 100 may include an OLED (Organic Light-Emitting semiconductor) display panel 1, a distance measuring assembly 2 and a Light equalizing sheet 3, wherein the distance measuring assembly 2 is located at a side away from the OLED display panel 1 for displaying. The distance measuring assembly 2 can determine the spacing distance between the distance measuring assembly 2 and the obstacle by emitting light and according to the light energy reflected by the emitting light. Specifically, the distance measuring assembly 2 may include an emitting portion 21 and a receiving portion 22, the light uniformizing sheet 3 may be disposed corresponding to the emitting portion 21, and an area of the light uniformizing sheet 3 is larger than a preset specification, so that a luminous flux of light emitted from the emitting portion 21 after passing through the light uniformizing sheet 3 incident into a unit area of the OLED display panel 1 is reduced to be smaller than or equal to a preset luminous flux corresponding to an energy density smaller than an energy density required to excite pixels of the OLED display panel 1 to perform self-luminescence. Therefore, on the one hand, the distance measuring assembly 2 can emit light through the OLED display panel 1, distance detection is achieved, holes are prevented from being formed in the OLED display panel 1, screen occupation ratio is favorably improved, on the other hand, luminous flux is reduced through the light equalizing sheet 3, and white spots caused by the fact that energy of the light emitted by the emitting portion 21 causes the OLED display panel 1 to emit light and the electronic device 100 can be avoided.

In this embodiment, as shown in fig. 2, the electronic device 100 may further include a first light gathering member 4, where the first light gathering member 4 is disposed corresponding to the emitting portion 21, and the first light gathering member 4 is located between the emitting portion 21 and the light equalizing sheet 3, and may be configured to gather the light from the emitting portion 21 and scatter the light from the emitting portion 21, so as to change the outgoing propagation light of the light, so that the light may be transmitted into the light equalizing sheet 3 from various directions, which is beneficial for uniform distribution of the light in the light equalizing sheet 3, thereby reducing the light flux in each unit area, and reducing the probability of white spots occurring on the OLED display panel 1. The first light gathering member 1 may include a light gathering sheet, such as a light gathering convex lens, which is not limited by the present disclosure.

In the above embodiments, still referring to fig. 2, the receiving portion 22 may correspond to a receiving area (i.e. the area defined by the left dashed line in fig. 2), that is, the light in the receiving area can be received by the receiving portion 22; similarly, the light uniformizer 3 may correspond to an emitting area (i.e., an area defined by a dotted line on the right side in fig. 2) overlapping a portion of the receiving area, so that when an obstacle is disposed corresponding to the overlapping area, the light received by the receiving part 22 can determine the separation distance between the obstacle and the electronic device 100. Wherein an intersection of the boundary of the receiving area and the boundary corresponding to the emitting area is located on the surface of the OLED display panel 1. For example, as shown in fig. 2, the intersection point a is located on a side surface of the OLED display panel 1 for displaying to reduce the influence of the high-reflection obstacle, or as shown in fig. 3, the intersection point a may be located on a surface of the OLED display panel 1 facing the distance measuring assembly 2, so as to balance the influence of the black substance on the distance measurement and the influence of the high-reflection obstacle on the distance measurement, and improve the accuracy of the distance detection.

In the above embodiments, still referring to fig. 3, the electronic device 100 may include a processor 5, and the processor may be configured to determine a separation distance between the distance measuring assembly 2 and an obstacle, where the obstacle blocks at least a part of an overlapping area between a receiving area corresponding to the receiving portion 22 and an emitting area corresponding to the light equalizing sheet 3, according to energy of the light received by the receiving portion 22, so as to ensure that the reflected light can be received by the receiving portion 21.

The linear relationship between the energy of the light received by the receiver 22 and the separation distance is shown, so that the separation distance between the obstacle and the electronic device 100 can be obtained by the energy. For example, the distance measuring device 2 may include a screen sensing device, and when the distance between the screen sensing device and the screen sensing device is less than the predetermined distance, the OLED display panel 1 may be switched to the off-screen state, and when the distance between the screen sensing device and the screen sensing device is greater than the predetermined distance, the OLED display panel 1 may be switched to the on-screen state. Or the ranging component 2 may also include a facial recognition component so that the facial recognition component may obtain a 3D image of the face through distance detection for unlocking or payment.

In the above embodiments, as shown in fig. 4, the electronic device 100 may further include a second light focusing element 6, the second light focusing element 6 is disposed corresponding to the receiving portion 22, and the second light focusing element 6 is configured to focus the reflected light and transmit the emitted light to the receiving portion 22, so as to reduce light loss and improve detection accuracy.

In the technical scheme of the present disclosure, the OLED display panel 1 may include a flexible OLED display panel, so that the electronic device 100 may be configured as a foldable electronic device, thereby enriching the posture of the electronic device 100, and facilitating to increase the screen area and carry along.
