For example, the foldable OLED display panel has a rectangular shape as shown in fig. 1, the first direction may be a transverse direction, that is, the folding axis L may specifically extend in the transverse direction, and the foldable OLED display panel may be bent around the folding axis L in the direction of arrow AB shown in fig. 1.

The display device may be specifically disposed in the first sub-display region and the second sub-display region. The signal transmitting part T1 and the signal receiving part T2 are specifically provided on both sides of the folding axis L, respectively.
In a specific implementation, the display panel is provided with a plurality of signal transmitting parts T1 and a plurality of signal receiving parts T2; the number of signal transmitting sections T1 is the same as the number of signal receiving sections T2. In the embodiment of the present invention, the display panel is provided with a plurality of signal transmitting units T1 and a plurality of signal receiving units T2, so as to avoid the problem that accurate receiving is difficult to achieve due to weak transmitted signals if only one signal transmitting unit T1 and one signal receiving unit T2 are provided. When the display panel is provided with the plurality of signal transmitting parts T1 and the plurality of signal receiving parts T2, the plurality of signal transmitting parts T1 may each be disposed at one region of a bezel region of the first display region S1, that is, for example, each be disposed at a left region of the first sub-bezel region S3 as shown in fig. 2, where the plurality of signal transmitting parts T1 are distributed in an array, and correspondingly, the plurality of signal receiving parts T2 may be disposed at a left region of the second sub-bezel region S4 as shown in fig. 2, where the plurality of signal receiving parts T2 are distributed in an array; when the display panel is provided with the plurality of signal transmitting parts T1 and the plurality of signal receiving parts T2, the plurality of signal transmitting parts T1 may also be uniformly distributed in the frame area of the first display area S1, that is, for example, the plurality of signal transmitting parts T1 may be arranged in a row in the first sub-frame area S3 shown in fig. 3, and correspondingly, the plurality of signal receiving parts T2 may be arranged in a row in the second sub-frame area S4 shown in fig. 3.

In the embodiment of the present invention, the signal emitting units T1 and the signal receiving units T2 are symmetrically distributed about the folding axis L, so that when the flexible display OLED display panel is folded, the signal receiving unit T2 has a high probability of successfully receiving the signal emitted by the signal emitting unit T1.
In a specific implementation, the signal emitting component T1 is an infrared emitting component, the signal receiving component T2 is an infrared receiving component, the infrared emitting component may specifically be an infrared organic emitting component, and the infrared receiving component may specifically be an infrared organic receiving component. In the embodiment of the present invention, the signal transmitting unit T1 is an infrared transmitting unit, and the signal receiving unit T2 is an infrared receiving unit, which are compatible with the manufacturing process of the display device in the display panel, and the signal transmitting unit and the signal receiving unit can be easily formed without greatly changing the manufacturing process of the display panel. In addition, the infrared organic diode is an organic light emitting device capable of emitting or receiving infrared light, and because the wavelength of the infrared organic diode is longer, the interference of surrounding visible light can be avoided. Therefore, a certain sensing characteristic can be effectively realized by using infrared light.
In specific implementation, referring to fig. 4, the infrared emitting part (i.e., the signal emitting part T1), the infrared receiving part (the signal emitting part T2), and the display device 3 are disposed in the same layer.

Moreover, because the thickness of the OLED organic light-emitting layer is about 300nm and is larger than that of the infrared organic light-emitting layer/the infrared absorption layer, the thickness of the display panel does not need to be additionally increased by the arrangement mode.
In specific implementation, as shown in fig. 4 and 5, the display panel further includes: the substrate comprises a substrate base plate 1, a driving transistor layer and a packaging layer, wherein the driving transistor layer is located on one surface of the substrate base plate 1, and the packaging layer 5 is located on one surface, deviating from the substrate base plate 1, of the driving transistor layer.

The display device, the infrared emission part, and the infrared reception part may be specifically disposed between the driving transistor layer and the encapsulation layer 5. The substrate 1 may be a PI substrate.
In specific implementation, the absorption waveband of the infrared absorption layer is consistent with the emission waveband of the infrared light-emitting layer. In the embodiment of the invention, the absorption waveband of the infrared absorption layer is consistent with the emission waveband of the infrared light emitting layer, so that infrared light emitted by the infrared emission component is just received by the infrared receiving component, and the effective detection of the infrared light emitted by the infrared emission component is realized.
In a specific implementation, as shown in fig. 5, the display device and the infrared emission component may be a top emission device, the anode 31 is located on a side of the cathode 32 facing the substrate 1, the first anode 41 is located on a side of the first cathode 42 facing the substrate 1, and the second anode is located on a side of the second cathode facing the substrate. The first cathode 42 of the ir emitting component and the second cathode of the ir receiving component may use electrodes with higher transmittance or transparent electrodes, such as Ag, Mg/Ag, etc., which is beneficial for the ir emitting component to emit ir more effectively and the ir receiving component to receive ir more effectively. The first anode 41 of the infrared emitting component and the second anode of the infrared receiving component can use electrodes with higher reflectivity, such as ITO/Ag/ITO, ITO/Mo/ITO, etc., so that the infrared emitting component can more effectively emit infrared light through the microcavity effect, and light received by the infrared receiving component is not lost.
In specific implementation, the material of the infrared light emitting layer may be an organic material emitting near-infrared light of 800nm to 1500nm, such as a benzothiadiazole derivative or a benzoselenadiazole derivative as a small molecule synthesized by a receptor; the infrared absorption layer is made of naphthalocyanine.
