And, the adjacent light emitting devices are connected by a connection line 30, the connection line 30 includes a metal line and an insulating layer wrapping the metal line, and the insulating layer may be a flexible material or a non-flexible material, so as to implement flexible connection or rigid connection of the connection line 30. It should be noted that the connection lines 30 between the light emitting devices in the same row are used for transmitting the scan signals of the stretchable display panel, and the connection lines 30 between the light emitting devices in the same column are used for transmitting the data signals of the stretchable display panel.
In addition, in the structure shown in fig. 1, there is a first sensing line 31 between the light emitting devices in the same row, and the first sensing line 31 is used for sensing the stretching length of the stretchable display panel in the X direction to control some or all of the second light emitting devices 12 to emit light according to the stretching length in the X direction, so as to maintain the resolution of the display panel.

In the embodiment of the present invention, as shown in fig. 2, the protection device is located on a side of the light emitting device facing away from the first stretchable substrate 1, the protection device includes a second stretchable substrate 2 and a plurality of second protrusions 20 located on the second stretchable substrate 2, the second protrusions 20 are disposed in one-to-one correspondence with the first protrusions 10, as in the structure shown in fig. 1, the second protrusions 20 also extend to two opposite sides of the second stretchable substrate 2 along the column direction Y, the plurality of second protrusions 20 are arranged in parallel along the row direction X, and the projection of the second protrusions 20 on the first stretchable substrate 1 and the projection of the first protrusions 10 on the first stretchable substrate 1 overlap in one-to-one correspondence.
Based on this, the first light emitting devices 11 are located between the first protrusions 10 and the second protrusions 20, and the second light emitting devices 12 are located in the gaps between the first protrusions 10 and also in the gaps between the second protrusions 20, and since the hardness of the first protrusions 10 is greater than that of the first stretchable substrate 1 and the hardness of the second protrusions 20 is greater than that of the second stretchable substrate 2, the first light emitting devices 11 and the second light emitting devices 12 can be protected by the first protrusions 10 and the second protrusions 20, and the first light emitting devices 11 and the second light emitting devices 12 are prevented from being damaged by impacts from both sides of the display panel, such as impacts from below the first stretchable substrate 1 by the first protrusions 10 and impacts from above the second stretchable substrate 2 by the second protrusions 20.
It should be noted that the first light emitting device 11 may be fixed between the first protrusion 10 and the second protrusion 20 through an adhesive layer, may be fixed between the first protrusion 10 and the second protrusion 20 through another film layer, or may not be fixed with the first protrusion 10 and the second protrusion 20, and details are not repeated here.

Since the third stretchable substrate 3 is also made of a flexible material such as a stretchable polymer, the surface of the third stretchable substrate 3 in contact with the first light emitting device 11 is a flexible surface, so that the contact damage of the second protrusions 20 to the light emitting device and the like can be further reduced while the stretch property and the impact resistance property of the protection device are maintained, and the manufacturing process of the structure shown in fig. 6 is relatively simple and more convenient to implement compared with the structure shown in fig. 5.
