[0002] Compared with hard-screen OLED panels, flexible OLED panels have advantages such as being thin, light, flexible and bendable, but they have problems such as wrinkles under large-size structures. Therefore, hybrid products are usually used, that is, the upper cover is changed to thin film packaging, which can achieve multiple effects of thin thickness, light weight, high strength and no wrinkles.
[0003] However, in order to perform touch control on the encapsulation layer, a circuit module needs to be set up. However, due to the use of thin film encapsulation, the circuit module cannot be directly bonded to the surface of the thin film encapsulation layer and must be set on the outside of the thin film encapsulation layer, which results in the need to set a border of a certain width, affecting the user experience.

[0066] The touch detection electrode layer includes a plurality of detection signal lines, and the touch drive electrode includes a plurality of drive signal lines.

The outer screen 20 is bonded and fixed to the inner screen 10 by the optically transparent adhesive layer 30, and the visible light emitted by the flexible OLED panel is emitted through the optically transparent adhesive layer 30 and the outer screen 20.
[0072] Example 2
[0073] like Figure 3 As shown, Example 2 is similar to Example 1 (see Figure 1 ), the difference of this embodiment is that:
[0074] The flexible OLED panel also includes a connection module 22, through which the touch detection electrode layer and the touch driving electrode are electrically connected to the touch module 21; the connection module 22 is arranged in the first area 201 and is located outside the thin film encapsulation layer 4.
