背景技术
柔性触控显示装置具有薄、轻、宽视角、主动发光、可柔性显示以及简单、直接的操作等优点，已被列为极具发展前景的下一代显示技术。
现有技术中，通常先采用覆膜设备将衬底薄膜贴覆在玻璃基板上，然后以玻璃基板为支撑，在衬底薄膜上制作触控结构层，制作完成后，将衬底薄膜与玻璃基板分离，得到柔性触控膜。
覆膜设备通常包括基板吸附装置和位于基板吸附装置下方的贴覆装置，其中：基板吸附装置具有朝向贴覆装置的承载面，承载面上具有第一吸附结构；贴覆装置包括与承载面相对设置的网板、位于网板下方的负压箱，以及设置负压箱内的压辊。在覆膜前，基板吸附装置将玻璃基板吸附于承载面上，玻璃基板朝向网板的一侧表面具有光胶，贴覆装置将衬底薄膜吸附于网板上；当覆膜时，压辊挤压网板并平行于承载面运动，从而将衬底薄膜与玻璃基板通过光胶紧密贴合。
然而，现有技术存在的缺陷在于，在贴覆薄膜时，压辊对薄膜有一定的挤压和拉扯，使薄膜出现张应力。在后续制程中，薄膜沿压辊移动的方向容易出现收缩，导致玻璃基板出现翘曲现象，从而使贴覆在玻璃基板上的薄膜易出现吸真空异常、流动异常等现象，严重影响触控薄膜的产品品质。

在本公开的实施例中，隆起表面11隆起的凸度d与衬底基板3的厚度a满足：d≤2a。将隆起表面11的凸度在该范围内取值，可以减少基板3的翘曲，从而提高薄膜4与基板3的贴合度。

在本实施例中，覆膜设备还包括与第一驱动装置连接的控制装置，用于当覆膜设备启动后，控制第一驱动装置以驱动压辊22将薄膜4压向隆起表面11并在薄膜4远离隆起表面11的一侧滚动，从而第一吸附结构23与压辊22相对的部分与薄膜4分离，使薄膜4与压辊22相对的部分与基板3紧密贴合。采用该结构设计，控制装置通过控制第一驱动装置以驱动压辊22，从而实现自动化贴覆薄膜4。
在一实施方式中，覆膜设备还包括用于驱动转轴12的第二驱动装置，第二驱动装置与控制装置连接。在固定基板3时，控制装置控制第二驱动装置以驱动转轴12将基板固定装置1旋转至朝向薄膜承载装置2的第一转动位置；当基板3固定后，控制装置控制第二驱动装置以驱动转轴12将基板固定装置1旋转至背向薄膜承载装置2的第二转动位 置。
