一种盖板及其制备方法、显示装置 技术领域
本申请涉及显示技术领域，具体涉及一种盖板及其制备方法、显示装置。
 背景技术
在现代化社会中，显示屏广泛应用于家电、移动设备、汽车等各个领域，逐渐成为工业化设备的重要组成部分。现代的电子设备通常都会要求显示屏熄灭时的颜色与非显示区尽可能一致，即息屏一体黑要求。
为了达到这一目的，现有技术中，通常在显示屏外围的非显示区上印有黑色油墨层，通过黑色油墨层对结构件进行遮挡，然后再在黑色油墨层上贴上全透性玻璃，如此，当显示屏发光时，黑色油墨层对于使用者而言并不显眼，且在显示屏熄灭时，它们之间的颜色也较为一致。该种结构的显示屏能够提高设备的美观性。
但在柔性显示装置中，为了实现弯折小半径，通常将材料的厚度以及胶的厚度变薄，但胶层厚度过薄会导致油墨的覆盖率变差，因此需要提供一种新的技术方案，既能保证油墨的覆盖率，又能实现弯折小半径。
