如图2、图3所示，所述玻璃背板1的表面平整光滑，在所述玻璃背板1的内表面上刻蚀制作电路层3，并且在所述电路层3上涂布一层反射层5。所述反射层5为油漆或者纳米涂料，其材料组成可以为BaSO4，CaCO3，TiO2等无机粒子,这种材料可附着在多数金属、塑料及玻璃表面上。所述反射层5还具有较高的光学稳定性。随后，将光源6通过表面贴装技术贴装在所述玻璃基板1上，在本实施例中光源6为多根间隔分布的LED灯条。
如图4所示，为本发明实施例中的显示装置的丝印外观图案。更佳地，可以在所述玻璃背板1的外表面即电路层3的相反面上丝印外观图案，形成丝印层2，以此来增加产品的外观性能。
如图5所示，在组装了光源6的玻璃背板1上依次粘贴中框支架4，然后在所述中框支架4内放置扩散板7以及光学膜片8，然后粘贴液晶模组9，即可完成组装。
如图6所示，将所述液晶模组9中的驱动PCB（如X-PCB、Y-PCB等）以及TCON12也集成在所述玻璃背板1上，然后在所述玻璃背板1上设置连接器10，所述液晶模组9中的液晶屏幕可以通过COF11插进所述连接器10，实现与所述玻璃背板1的连接。这样可以进一步的提高集成度，提升产品的组装效率，降低产品的成本。
本实施还提供一种显示装置的制备方法：取一玻璃背板，在所述玻璃背板上制作电路层，然后在所述电路层上涂布一层反射层，并将光源贴装在所述玻璃背板上；在所述玻璃背板背面，即电路层的反面，制作丝印外观图案，形成丝印层；将所述玻璃背板固定在中框支架内，随后放置扩散板、光学膜片，粘贴液晶模组，并将液晶模组通过COF与连接器连接，实现液晶模组与所述玻璃背板相连接。
以上对本申请实施例所提供的一种显示装置及其制备方法进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的技术方案及其核心思想；本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例的技术方案的范围。
