Fig. 1 is a schematic structural view of an electronic device 100 according to an exemplary embodiment, and fig. 2 is a schematic sectional view of the electronic device 100 according to an exemplary embodiment. As shown in fig. 1 and 2, the electronic device 100 may include an OLED (Organic Light-Emitting Diode) display panel 1, a distance measuring assembly 2, and a Light homogenizing sheet 3, wherein the distance measuring assembly 2 is located at a side remote from the OLED display panel 1 for display. The distance measuring assembly 2 can determine the distance between the distance measuring assembly 2 and the obstacle by emitting light and measuring the light energy reflected by the emitted light. Specifically, the ranging assembly 2 may include an emitting part 21 and a receiving part 22, the light homogenizing sheet 3 may be disposed corresponding to the emitting part 21, and an area of the light homogenizing sheet 3 is larger than a preset specification, so that a luminous flux of light emitted from the emitting part 21 in a unit area incident to the OLED display panel 1 after passing through the light homogenizing sheet 3 is reduced to be smaller than or equal to a preset luminous flux, which corresponds 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 one hand, the distance measuring component 2 can emit light through the OLED display panel 1, so that distance detection is realized, holes are avoided in the OLED display panel 1, the screen duty ratio is improved, on the other hand, the luminous flux is reduced through the light-equalizing sheet 3, and the phenomenon that the OLED display panel 1 emits light and white spots appear on the electronic equipment 100 due to energy brought by the light emitted by the emitting part 21 can be avoided.

In this embodiment, still as shown in fig. 2, the electronic device 100 may further include a first light-focusing element 4, where the first light-focusing element 4 is disposed corresponding to the emission portion 21, and the first light-focusing element 4 is located between the emission portion 21 and the light-homogenizing sheet 3, and may be used to gather light from the emission portion 21 and scatter the light from the emission portion 21, so as to change the outgoing and propagating light of the light, so that the light may be transmitted into the light-homogenizing sheet 3 from all directions, which is beneficial for the light to be uniformly distributed in the light-homogenizing sheet 3, thereby reducing the luminous flux in each unit area and reducing the probability of white spots of the OLED display panel 1. The first light collector 4 may include a light collecting sheet, for example, a light collecting convex lens, which is not limited by the present disclosure.

In the above embodiments, as shown in fig. 2, the receiving portion 22 may correspond to a receiving area (i.e. an area defined by a left broken line in fig. 2), that is, the light within the receiving area may be received by the receiving portion 22; similarly, the light-equalizing sheet 3 may correspond to an emission area (i.e., an area defined by a right-hand broken line in fig. 2) that overlaps with a portion of the receiving area, so that when an obstacle is disposed corresponding to the overlapping area, the distance between the obstacle and the electronic apparatus 100 can be determined by the light energy received by the receiving section 22. 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 surface of the OLED display panel 1 for displaying, so as 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 ranging component 2, so as to balance the influence of the black material on the ranging and the influence of the high reflection obstacle on the ranging, and improve the accuracy of the distance detection.

In the above embodiments, still referring to fig. 3, the electronic device 100 may further include a processor 5, where the processor may be configured to determine, according to the energy of the light received by the receiving portion 22, a separation distance between the ranging module 2 and an obstacle, where the obstacle covers at least a portion 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, so as to ensure that the reflected light can be received by the receiving portion 22.

The energy of the light received by the receiving unit 22 is linearly related to the distance, so that the 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 the OLED display panel 1 may be switched to the off-screen state when the screen sensing device is spaced apart by a distance smaller than a predetermined distance, and the OLED display panel 1 may be switched to the on-screen state when the spacing distance is greater than the predetermined distance. Or the ranging component 2 may also include a facial recognition component such that the facial recognition component can derive a facial 3D image from 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 collecting member 6, where the second light collecting member 6 is disposed corresponding to the receiving portion 22, and the second light collecting member 6 is configured to collect the reflected light and transmit the reflected light to the receiving portion 22, so as to reduce light loss and improve detection accuracy.

In the technical scheme of the disclosure, the OLED display panel 1 may include a flexible OLED display panel, so that the electronic device 100 may be configured as a folding electronic device, enriching the posture of the electronic device 100, and being beneficial to improving the screen area and being convenient to carry.
