Comparative example 1
The procedure was as in example 1, except that the corresponding production parameters were adjusted as shown in Table 1.
Test method and apparatus
And (3) testing pen falling performance:
the test purpose is as follows: the impact resistance of the display device is represented by a test of pen drop performance;
the testing process comprises the following steps: a ball-point pen (12gf,. phi.0.5 mm, morning light marker) was dropped vertically from a height of 10cm, impacting a display device located directly below the pen. When the display device has no bright spots or broken bright spots, the height of the display device is increased by 1cm and falls down again; and until the display device appears bright spots and broken bright spots, the last falling height of the display device when the bright spots and the broken bright spots appear is the pen falling performance height.
