Two centers of the pixel element packaging area101are separated by a first distance X1 along the first direction91, are separated by a second distance X2 along a second direction92. The pixel element encapsulation area101is designed by stacking a multilayer encapsulation structure15on the substrate10, and the multilayer encapsulation structure15covers the light emitting unit16.

The plurality of first stretched signal line areas2are arranged in matrix, has a first curve. In the embodiment of the present invention, the first curve is an ellipse. Each first stretched signal line area2is connected to two short sides1012of the pixel element packaging area101, and is a metal signal line31,32,33made of at least one metal material connected in series with a via. The plurality of second stretched signal line areas3are arranged in matrix, has a second curve. In the embodiment of the present invention, the second curve is an ellipse. Each second stretched signal line area3is connected to two long sides1013of the pixel element packaging area101, and is a metal signal line31,32,33made of at least one metal material connected in series with a via. Both the first stretched signal line area2and the second stretched signal line area3are stacked on the substrate10with a multilayer package structure17, and the metal signal lines31,32,33will be packaged in the multilayer package structure17, and the metal signal lines31,32,33are connected in series with several layers of the multilayer packaging structure17.

The plurality of first transparent apertures4are arranged in matrix, each first transparent aperture4is surrounded by the first stretched signal line area2, and has an aperture ratio (Y %). The plurality of second transparent apertures5are arranged in matrix, each second transparent aperture5is surrounded by the second stretched signal line area3, and has the aperture ratio (Y %).

In an embodiment, the first transparent aperture4and the second transparent5are stacked with organic materials on the substrate10, and the inorganic material is removed. The substrate10is stacked with a support substrate102and a flexible substrate103. In an embodiment, the flexible substrate103further has a plurality of openings1031on the support substrate102. The opening1031is tapered, and the surface area of the opening1031near to the flexible substrate103is larger than the surface area of the opening1031near to the supporting substrate102. In an embodiment, the flexible substrate103further has a packaging layer13. In an embodiment, the packaging layer13and the flexible substrate102further have a plurality of through holes14on the support substrate102. The through hole14is tapered, and the surface area near to the encapsulation layer13is larger than the surface area near to the supporting substrate102.

The first transparent aperture4and the second transparent5are stacked with organic materials, and because of the removal of inorganic materials, the penetration loss caused by light passing through multiple layers of refraction is reduced, so that transparent apertures form high light transmission and stretchable. The first transparent aperture4and the second transparent5are removed components for display or telecommunication transmission, can greatly reduce the problems of broken wires of display components, so as to improve the effect of stretching and using the product. In the present invention, a single transmission is connected in series with the first stretched signal line area2and the second stretched signal line area3to avoid the situation that only a single line is broken due to stretching.

In the present invention, the first stretched signal line area2and the second stretched signal line area3of multiple layers are connected in series by a signal transmission, so as to avoid the situation that only a single line is broken due to stretching. The present invention is defined a curvature design value r=(X1*X2*Y %/π)0.5, where X1 is the first distance, X2 is the second distance, Y % is the aperture ratio, and x is the circumference ratio. The first stretched signal line area2has two first arc curves21and two second arc curves22, and the second arc curve22is near to the short side1012of the pixel element packaging area101, the second stretched signal line area3has two third arc curves34and two fourth arc curves35, the third arc curve34is near to the long side1013of the pixel element packaging area101, a radius of curvature of the first arc curve21, the second arc curve22, the third arc curve23and the fourth arc curve24are all between 0.5 times the curvature design value r and 5 times the curvature design value r.

Please refer toFIG.13, which is a simulated display result of a tensile test performed on the light emitting diode display device of the present invention. The pixel element packaging area101has a first Young's modulus, the first stretched signal line area2and the second stretched signal line area3have the same second Young's modulus, and the first transparent aperture4and the second transparent aperture5have the same third Young's modulus, the first Young's modulus is more than the second Young's modulus, and the second Young's modulus is more than the third Young's modulus. With this design, it needs to go through a stretching process during use or manufacturing process, because the tensile strength is the product of equivalent modulus and thickness (T=E*h). Due to thickness variation or shape variation, the stress distribution of the cross-section after stress is no longer kept uniform, and when the structure is stressed and stretched, the stress will concentrate on the position with weaker tensile strength.

As shown in the results in the figure, the main stretching position of the present invention is on the second transparent aperture5, and secondly on the pixel element packaging area101and the second stretching signal line area3. The pixel element packaging area101is the area with the largest structural Young's modulus in the product because the multilayer encapsulation structure15is not easy to be stretched during the stretching process. The second transparent5is removed components for display or telecommunication transmission, can greatly reduce the problems of broken wires of display components, so as to improve the effect of stretching and using the product. It is important to a single transmission is connected in series with the second stretched signal line area3to avoid the situation that only a single line is broken due to stretching.
