Embodiment 1
[0034] like Figure 4 As shown, an OLED display panel includes a substrate 4, an OLED module, and an encapsulation layer. The OLED module is arranged on the substrate 4, and the encapsulation layer is arranged on the periphery and the front of the OLED module; wherein the OLED module includes an anode layer 5, a cathode layer 7 and a The organic layer 6 between the anode layer 5 and the cathode layer 7 , the anode layer 5 is disposed on the first layer on the substrate 4 , and the encapsulation layer is disposed on the front of the cathode layer 7 . The light-emitting surface of the display panel is located on the back surface 42 of the substrate. There are perforations in the structure formed by the OLED module and the encapsulation layer. The through-holes are respectively filled with conductive substances to form cathodes and anodes. pixel, each light-emitting pixel in the OLED module is provided with a perforation 11, wherein the perforation 11 passes through the organic l...
Embodiment 2
[0038] like Figure 5 As shown, the structure of this embodiment is roughly the same as that of Embodiment 1, except that the OLED module in the OLED display panel adopts an inverted structure. The cathode layer 7 of the OLED module is arranged on the first layer on the substrate 4 , and the encapsulation layer is arranged on the front of the anode layer 5 . The light-emitting surface of the display panel is located on the back of the substrate. There are perforations in the structure formed by the OLED module and the encapsulation layer. The through-holes are filled with conductive substances to form the cathode and anode respectively. The structure of the perforations is refined to each light-emitting pixel in the OLED module. , each light-emitting pixel in the OLED module is provided with a perforation 11, wherein the perforation 11 passes through the organic layer 6 and the anode layer 5, and the encapsulation layer is provided with two perforations 10 corresponding to eac...
Embodiment 3
[0041] like Image 6 As shown, the structure of this embodiment is roughly the same as that of Embodiment 1, the difference is that the encapsulation layer in the OLED display panel is encapsulated by the traditional encapsulation back cover 82, wherein the encapsulation layer includes the encapsulation back cover 82 and the encapsulation plastic frame 2 The encapsulation back cover 82 adopts a transparent glass flexible encapsulation panel and is arranged on the front of the OLED module. The encapsulation back cover 82 reserves mounting holes as perforations 10, and the anode and the cathode respectively extend outward through the mounting holes on the encapsulation back cover 82 and are exposed on the encapsulation back cover. 82, the anode and cathode are sealed between the mounting holes. The encapsulating plastic frame 2 is arranged around the OLED module, one end of which is in sealing contact with the encapsulating back cover 82 , and the other end is in sealing contact...
