具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
本发明实施例提供了一种显示装置及其制备方法，该显示装置由于在显示面板与背光模组之间不需要设置黑色胶带条粘接，而是通过侧面的粘接层进行粘接，进而使显示装置的边框宽度不再受黑色胶带 条宽度的限制，可将显示装置的边框宽度做的较窄，便于实现显示装置的窄边框设计。
请参考图1，本发明一种实施例提供的显示装置，包括显示模组，显示模组包括叠置的显示面板和背光模组1，显示面板包括液晶盒2、位于液晶盒2朝向背光模组1一侧的下偏光片3、位于液晶盒2背离背光模组1一侧且至少一对边缘探出液晶盒2的层，显示模组中层边缘探出液晶盒2的侧面设有粘接层5，在显示模组设有粘接层5的任意一个侧面中，粘接层5与背光模组1的侧面、下偏光片3的侧面、液晶盒2的侧面、层探出液晶盒2的边缘朝向背光模组1的表面粘接，且沿垂直于其粘接的液晶盒2侧面的方向，粘接层5的厚度t小于等于设定厚度。
上述显示装置中，显示面板与背光模组1之间不需要设置黑色胶带条粘接，而是通过形成在液晶盒2的侧面、下偏光片3的侧面、背光模组1的侧面和层探出液晶盒2的边缘朝向背光模组1的表面的粘接层5进行粘接，进而使显示装置的边框宽度不再受黑色胶带条宽度的限制，可将显示装置的边框宽度做的较窄，便于实现显示装置的窄边框设计。
为了能够使显示装置进一步地实现窄边框设计，如图1所示，上述显示装置的每一个粘接层5中，设定厚度可以为0.1mm。
一种具体的实施方式中，参见图1，上述显示面板还包括在液晶盒2背离背光模组1的一侧的上偏光片4，且层为上偏光片4。
另一种具体的实施方式中，如图1所示，上述显示面板还包括在液晶盒2背离背光模组1的一侧的上偏光片4和透明盖板6，透明盖板6位于上偏光片4背离液晶盒2的一侧，且层为透明盖板6；透明盖板6可以为玻璃盖板。
具体地，如图1所示，在显示模组设有粘接层5的任意一个侧面中，当上偏光片4的边缘探出液晶盒2且作为所述层时，上偏光片4探出液晶盒2的宽度小于等于0.1mm。
当上偏光片4的边缘不探出液晶盒2，而透明盖板6作为所述层时，在显示模组设有粘接层5的任意一个侧面中，透明盖板6的边缘探出液晶盒2的宽度可以为0.3-0.5mm，例如透明盖板6的边缘探出液晶盒2的宽度可以为0.3mm、0.35mm、0.4mm或0.5mm。
在本发明的实施例中，在显示模组设有粘接层5的任意一个侧面中，液晶盒2探出背光模组1的侧面，且探出的宽度可以为0.1mm；同时，显示装置采用的粘接层5可以为热熔胶或UV胶，如：聚酯类热熔胶、聚酰胺类热熔胶、乙烯及其共聚物类(EVA)热熔胶、水基型热熔胶、压敏型热熔胶等。当然，粘结胶还可以为满足要求的其他类型的粘接剂，这里不再一一列举。
另外，如图2所示，本发明实施例还提供了一种上述实施例提供的任意一种显示装置的制备方法，包括：
步骤S11，将显示面板和背光模组1叠置，其中，显示面板包括液晶盒2、位于液晶盒2朝向背光模组1一侧的下偏光片3、位于液晶盒2背离背光模组1一侧且至少一对边缘探出液晶盒2的层，层探出液晶盒2的边缘朝向背光模组1一侧的表面与液晶盒2以及背光模组1的侧面形成粘结胶涂覆区间，如图5a所示；

通过上述制备方法制备的显示装置的层、液晶盒2、下偏光片3和背光模组1通过粘结胶A固化的粘接层5粘接在一起，不需要黑色胶带条，并且能够去除固化后多余的粘结胶A，进而使显示装置的边框宽度不再受黑色胶带条宽度的限制，因此，通过该制备方法制备的显示装置便于实现窄边框设计。
在上述制备方法制备的显示装置中，层可以为上偏光片4，也可以为透明盖板6，并且，上述制备方法可以包括多种具体制备方法：

步骤S23，去除固化后多余的粘结胶A以得到粘接层5，同时对上偏光片4进行切割，以使上偏光片4探出液晶盒2的边缘的宽度小于等于设定值，如图5c所示，其中，每一个粘接层5在沿垂直于粘接层5粘接的液晶盒2侧面的方向上的厚度t小于等于设定厚度；
步骤S24，在上偏光片4背离液晶盒2的一侧贴附透明盖板6，如图5d所示。
为了保证显示装置的产品质量，防止在涂覆粘结胶时粘结胶渗入显示装置的上偏光片4、液晶盒2、下偏光片3以及背光模组1之间，在粘结胶涂覆区间内涂覆粘结胶的步骤S22中，对上偏光片4提供朝向背光模组1的压力、且为背光模组1提供朝向上偏光片4的压力。
制备方法二：
当上述显示装置的层为上偏光片4时，如图4以及图6a-6f所示，上述制备方法可以包括以下具体步骤：
步骤S31，将显示面板和背光模组1叠置，如图6a所示，其中，显示面板包括液晶盒2、位于液晶盒2朝向背光模组1一侧的下偏光 片3、位于液晶盒2背离背光模组1一侧且至少一对边缘探出液晶盒2的上偏光片4；
步骤S32，对上偏光片4探出液晶盒2的边缘进行切割，以使上偏光片4探出液晶盒2边缘的宽度小于等于设定值，如图6b所示，；
步骤S33，在上偏光片4背离液晶盒2的一侧贴附透明盖板6，同时，在背光模组1背离液晶盒2的一侧形成背光模组保护层7，且背光模组保护层7与上偏光片4探出液晶盒2的边缘对应的边缘探出背光模组1，上偏光片4探出液晶盒2的边缘朝向背光模组1一侧的表面与液晶盒2的侧面、下偏光片3的侧面、背光模组1的侧面以及背光模组保护层7的边缘朝向液晶盒2的一侧表面形成粘结胶涂覆区间，如图6c所示；
步骤S34，在粘结胶涂覆区间内涂覆粘结胶A、并对涂覆的粘结胶A进行固化，以使固化后的粘结胶A与背光模组1的侧面、下偏光片3的侧面、液晶盒2的侧面、上偏光片4中探出液晶盒2的边缘朝向背光模组1一侧的表面、以及背光模组保护层7的边缘朝向液晶盒2的一侧表面粘接，如图6d所示，并且每一个粘结胶涂覆区间中，沿垂直于液晶盒2与该粘结胶涂覆区间对应的侧面的方向，涂覆的粘结胶A厚度为0.3-0.5mm，实际涂覆的粘结胶A厚度可以为0.3mm、0.35mm、0.4mm或0.5mm；
步骤S35，采用刮胶工艺去除固化后多余的粘结胶A以得到粘接层5，如图6e所示，其中，每一个粘接层5在沿垂直于粘接层5粘接的液晶盒2侧面的方向上的厚度t小于等于设定厚度；

在上述制备方法中，由于设有在背光模组1背离液晶盒2的一侧形成背光模组保护层7的步骤S33，采用背光模组保护层7能够在生产过程中保护背光模组1，因此，该制备方法能够在提高显示装置的产品质量的同时还能提高产品合格率。
在采用刮胶工艺去除固化后多余的粘结胶A的步骤S35中，采用镭射测距工艺监测剩余粘结胶A的厚度，由于镭射测距的测距精度高，在实时监测剩余粘结胶A的厚度的同时，还能使剩余粘结胶A厚度满足生产要求，并进一步保证显示装置的粘接层5的制造精度。
制备方法三：
上述显示装置的层还可以为透明盖板6，并在透明盖板6与液晶盒2之间设有上偏光片4，如图2以及图7a-7d所示，上述制备方法包括以下具体步骤：

在上述制备方法三中，采用激光切割对固化后多余的粘结胶A进行去除，由于激光切割技术具有切割质量好、切割速度快、切割效率高的特点，因此，采用激光切割技术对固化后多余的粘结胶A进行去除，可以提高显示装置的产品质量和生产效率。同时，为了在激光切割过程中保护透明盖板6，在透明盖板6与切割粘结胶A的割痕对应边缘朝向背光模组1的侧面覆盖有铝膜。
以上实施方式仅用于说明本发明，而并非对本发明的限制，有关技术领域的普通技术人员，在不脱离本发明的精神和范围的情况下，还可以做出各种变化和变型，因此所有等同的技术方案也属于本发明的范畴，本发明的专利保护范围应由权利要求限定。
