在一种实施例中，所述第一过孔、第二过孔与所述第三过孔内设有透明材料，在设置第一过孔、第二过孔和第三过孔后，可在第一过孔、第二过孔和第三过孔内填充透明材料，使得显示装置平整，且保护层整面设置于所述光学胶上时，不会出现弯曲变形的问题。
在一种实施例中，所述光学胶包括OCA胶、UV-OCA胶中的一种，其中UV-OCA是指添加了紫外光固化剂的OCA胶，对UV-OCA胶进行紫外光照射，可加快OCA胶的固化，UV-OCA相较于OCA胶具有更好的性能。
在一种实施例中，所述显示装置还包括电子元件，所述电子元件包括摄像头，在摄像头采光时，光学胶形成有第一过孔，使得摄像头采光更好，提高了摄像头的摄像效果。
在一种实施例中，所述盖板包括透光层，所述透光层设置于对应显示位置的显示区内，所述显示区围绕所述电子元件设置区设置。
在一种实施例中，所述透光层的材料包括透明玻璃。
在一种实施例中，所述盖板还包括油墨层，所述油墨层设置于遮光区，所述油墨层与所述透光层的厚度相等，其中，所述遮光区位于所述显示区和所述电子元件设置区之间，为避免显示区的光线在盖板中出现反射、折射等现象，影响电子元件采光，可使得盖板在遮光区采用油墨层，使得显示区内的光线不会影响到电子元件设置区的采光，电子元件设置区采光不会影响到显示区，且对于显示装置，会在显示区和电子元件设置区之间设置遮光区，例如图6中会在遮光区设置遮光胶，使得显示区的光线不会进入电子元件设置区，影响电子元件，电子元件设置区的光线也不会进入显示区，影响显示，所以盖板在遮光区设置油墨层不会对显示产生影响，且能提高电子元件的采光效果和采光准确性。
在一种实施例中，所述盖板还包括油墨层，所述透光层设置于所述遮光区，所述油墨层设置于所述透光层上，其中，所述遮光区位于所述显示区和所述电子元件设置区之间。
如图8所示，本申请实施例提供一种显示装置制备方法，该显示装置制备方法包括：

本申请实施例提供一种显示装置制备方法，该显示装置制备方法制备的显示装置包括盖板、光学胶、偏光片和显示面板，所述盖板在对应电子元件设置位置的电子元件设置区，形成有第一过孔，所述电子元件的采光路径经过所述第一过孔；所述光学胶设置于所述盖板下，在所述电子元件设置区形成有第二过孔；所述偏光片设置于所述光学胶下，在所述电子元件设置区形成有第三过孔；所述显示面板，设置于所述偏光片下，其中，所述第一过孔、第二过孔和第三过孔存在重合部分；通过在盖板上形成第一过孔，使得光学胶形成在盖板上时，光学胶无法在第一过孔对应区域形成，从而使得光学胶在电子元件设置区也形成第二过孔，从而使得光学胶不会存在厚度不同的区域，且电子元件设置区内无光学胶，第一过孔、第二过孔和第三过孔存在重合区域，使得光线从第一过孔、第二过孔和第三过孔进入电子元件，从而避免了盲孔区域存在气泡的问题，解决了现有显示装置存在OCA胶在对应盲孔区域存在气泡，影响摄像效果的技术问题。
在一种实施例中，所述在显示面板上贴附偏光片的步骤包括：
提供偏光片，所述偏光片在电子元件设置区形成第三过孔；
将偏光片贴付在显示面板上，在贴附偏光片前，先在偏光片上形成第三过孔，使第三过孔对应显示面板上的电子元件设置区，从而将偏光片贴附在显示面板上，该方法可避免在形成过孔时损伤显示面板，或者将偏光片贴附在显示面板上后，在电子元件设置区形成第三过孔，使得第三过孔位置较为准确，对应显示面板上的电子元件设置区和过孔。

提供透光层；
在遮光区形成油墨层，得到盖板，所述油墨层在电子元件设置区形成有第一过孔，所述透光层与所述油墨层的厚度相等，所述遮光区位于显示区和电子元件设置区之间；在提供盖板时，可先在盖板的遮光区形成油墨层，使得油墨层能够对电子元件设置区和显示区起到间隔作用，从而避免显示区的光线与电子元件设置区的光线发生串扰，从而提高电子元件的采光效果。
在一种实施例中，所述提供盖板的步骤包括：
提供透光层，在所述电子元件设置区形成第一过孔；
在遮光区形成油墨层，得到盖板，所述遮光区位于显示区和电子元件设置区之间。
根据以上实施例可知：
