Example Embodiment
[0041] Experimental example 1
[0042] The following will introduce and compare Examples 1 to 6 using different first curing temperature (indicated by T1 below) and second curing temperature (indicated by T2 below) to respectively cure the first flexible layer and the second flexible layer. The flexible displays of Example 1 to Comparative Example 2. In addition, the flexible displays of Example 1 to Example 6 and Comparative Example 1 to Comparative Example 2 were measured for the number of bubbles between the first flexible layer and the buffer layer three times in three process stages, of which three process stages They are: 1) after curing the first flexible layer and before forming the buffer layer; 2) after the heat treatment process on the amorphous silicon layer and before the excimer laser annealing process; 3) after the heat treatment process on the interlayer insulating material layer and Before forming the second metal layer. The measurement data of the number of bu...
Example Embodiment
[0051] Experimental example 2
[0052] Please refer to figure 2 , figure 2 The static thermomechanical analysis spectra of the second flexible layer of the flexible displays of Example 7 to Example 9 and Comparative Example 3 are shown. in figure 2 The x coordinate in is the deformation amount of the second flexible layer (unit is ppm), the y coordinate is the ambient temperature (unit is °C), and the slope is the coefficient of thermal expansion (unit is ppm / °C). In addition, in figure 2 , The second flexible layer respectively has a glass transition temperature ( figure 2 In Tg1) when the first thermal expansion coefficient is between the first glass transition temperature and the second glass transition temperature ( figure 2 Is represented by Tg2) between the second thermal expansion coefficient and the third thermal expansion coefficient greater than the second glass transition temperature.
[0053] The parameter information used in preparing the second flexible layer of...
