[0062] A second embodiment of the present invention relates to a stretchable display device. The second embodiment is substantially the same as the first embodiment, the main difference is that in the first embodiment, a groove surrounding the pixel defining region and penetrating the pixel defining layer is formed in the pixel defining layer 52, and the second water and oxygen barrier The layer 42 is deposited at least on the surface of the trench and its surrounding rigid island, so that the trench 521 and the first water-oxygen barrier layer 41 form a sealed space surrounding the light-emitting layer. In the second embodiment of the present invention, no groove 521 is formed on the pixel defining layer 52, and the second water and oxygen barrier layer 42 completely covers and exceeds the entire pixel defining layer 52 to form a seal with the first water and oxygen barrier layer 41. Space, so that the luminescent layer is wrapped in the sealed space. This implementation man...

[0066] The third embodiment of the present invention relates to a manufacturing method of a stretchable display device. see Figure 13 , the manufacturing method of this embodiment includes step 101 to step 103.

[0067] Step 101 : providing a stretchable substrate 1 .

[0068] Step 102: Form a plurality of rigid islands 2 on the stretchable substrate 1, and the plurality of rigid islands 2 are arranged at intervals.

[0069] Step 103 : forming stretchable wires 3 on the stretchable substrate 1 , and forming a pixel package on the rigid island 2 . Wherein, the stretchable wire 3 is connected to the pixel package to form a power supply circuit of the pixel package.

[0070] Please continue to refer to the cross-sectional structure of the stretchable display device manufactured according to the manufacturing method of this embodiment figure 1 . in, figure 1 Only a cross-sectional structure of a rigid island 2 on a stretchable substrate 1 and a pixel package thereon is show...

Abstract

The invention relates to the field of display technology, and discloses a stretchable display device, a manufacturing method thereof, and electronic equipment. In the present invention, the device includes: a stretchable substrate, a stretchable wire, and a plurality of rigid islands; the stretchable wire and the plurality of rigid islands are all arranged on the stretchable substrate; wherein, the plurality of rigid islands are arranged at intervals On the stretchable substrate, a pixel package body is formed on the rigid island; the stretchable wire is connected to the pixel package body to form a power supply circuit of the pixel package body. The invention connects the rigid independently packaged light-emitting pixel islands through stretchable wires, thereby realizing reliable electrical connection conditions, effective packaging and structural stability of the light-emitting pixels under stretchable conditions.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a stretchable display device, a manufacturing method thereof, and electronic equipment. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED for short) display is called a dream display, and has a bright application prospect in the display field. The organic layer in the OLED device is very sensitive to water vapor and oxygen. The water and oxygen infiltrated from the outside world are the main factors that cause the performance degradation and shorten the life of the OLED device. Therefore, packaging technology is very important for OLED display. With the gradual maturity of organic light emitting diode display technology, people increasingly expect organic light emitting display devices to have stretchability, that is, they can extend / extend or shrink and bend when being pulled. [0003] The inventors have fo...
