请参阅图6，另一实施方式中，所述透明盖板10边缘设有第一装配边13，所述遮光区12包括远离所述透光区11的一侧的延伸区125，所述延伸区125覆盖所述第一装配边13，本实施方式的中第二内表面包括延伸区位置的表面。所述延伸区也是油墨区。在上述任一实施方式中，所述延伸区125上层叠有所述电荷阻挡层，为了清楚区别电荷阻挡层位置，延伸区125上的电荷阻挡层标号为30A，其结构与材料与所述电荷阻挡层完全一致，可以理解为电荷阻挡层30延伸至所述延伸区125。所述第一装配边13用于与手机中框连接并通过粘胶层连接固定。所述延伸区125上层叠有电荷阻挡层可以增强对外部电荷的阻挡作用。
本申请实施例中，所述电荷阻挡层30的材料包括混合有电正性空穴材料的胶体。所述电正性空穴材料为钙钛矿类正性材料、苯胺类空穴材料、金属螯合物复合材料、苯乙烯类中的一种或者多种。所述电正性空穴材料与胶体混合后形成在所述遮光区12的第二内表面121上。
请参阅图7，在上述实施例基础上，本申请一实施例中，所述电荷阻挡层30包括层叠在所述遮光区12的基层31和设于所述基层31的数个间隔设置的孔32，数个所述孔32可以是盲孔或者贯穿所述基层31的通孔。所述数个所述孔32的排列方式不限定，只要不影响其加工及阻挡电荷的性能就可以。比如，数个孔32均匀分布在所述基层31上；或者由所述遮光区12到透光区11方向，即外部电荷进入的方向上，数个所述孔32由疏导密的排列设置。或者，数个所述孔呈阵列排列且每相邻两行的孔错位设置，即第一行的孔与第二行的两个相邻的之间的位置相对。当然也可以是其他方式排列。具体的，数个所述孔32均匀的设置于所述基层31上，所述基层31厚度大于等于1μm，本实施例中基层31厚度为5μm。所述孔32为通孔且贯穿所述基层31的相对两侧面，所述基层31的相对两侧面是指与所述第二内表面121接触的一侧面以及与该侧面背向设置的另一个侧面。所述基层31具有电正性特点，所述显示屏组件100外部的负电荷扩散至遮光区12后，数个所述孔32将负电荷吸附到孔32的内部，防止负电荷继续扩散至显示区内；而所述基层31自身的电正性空穴特性可以将所述孔32内吸附的负电荷固化消除。所述电荷阻挡层30通过纳米压印工艺、光罩工艺或者涂布压印工艺中的一种或多种组合形成。本实施例中，所述电荷阻挡层30通过纳米压印的方式形成，并通过UV光等方式固化，形成电荷阻挡层30的基层31采用空穴材料形成且基层31材料本身缺少电子，加上数个微孔32的总表面以及阻挡的作用，负电荷进入孔32内实现吸附固化，限制负电荷的进一步传输。而对于柔性显示屏来说，在透明盖板10的透光区11以外的非平面遮光区12形成数个孔32，采用纳米压印技术更容易制作及实现。
本申请一种实施例中，所述电荷阻挡层的数个孔323中，每两个相邻的所述孔32之间的距离大于等于10nm，该距离根据实际需要而选择，以保证可以实现对外部电荷的吸附和 阻挡。可以理解为所述电荷阻挡层30的孔32的密度与移动终端外部产生进入显示屏组件100的电荷大小有相应的变化趋势关系。比如，在显示屏组件100测试过程中可以确定其在使用过程中会产生电荷的量的范围，根据确定的电荷范围来设定所述孔32的密度和/或者孔32的尺寸，来保证可以完全阻挡外部电荷进入显示模组内部，即可以简单理解为，测试确定的电荷越大，对应设置的孔32的密度越大，这样可以对手机工作中显示屏的有效保护。
本申请另一实施例中，所述电荷阻挡层30包括设于所述遮光区12的表面的数个间隔设置的凸起结构，所述凸起结构可以是柱体、条形凸起等结构。
请参阅图8，本实施例一种实施方式中，所述凸起结构为凸设于所述第二内表面的柱体33，所述柱体可以是圆柱、棱形柱等。本实施例采用圆柱，数个所述柱体的排列方式不限定；所述柱体33自身具有电正性特点，所述显示屏组件100外部的负电荷扩散至遮光区12后，数个所述柱体33阻挡负电荷扩散并将负电荷吸附在柱体33外周面，防止负电荷继续扩散至显示区内，进一步可以对吸附的负电荷固化消除。所述电荷阻挡层30通过纳米压印工艺、转印、光罩工艺或者涂布压印工艺中的一种或多种组合形成。本实施例中，所述电荷阻挡层30通过纳米压印的方式形成，并通过UV光等方式固化。所述柱体33本身缺少电子，加上数个柱体33的表面构成具有足够大面积的吸附表面可以实现阻挡的作用，负电荷进入数个柱体33组成的电荷阻挡层30内，柱体33表面实现对电荷的吸附固化，限制负电荷的进一步传输。而对于柔性显示屏来说，在透明盖板10的透光区11以外的非平面遮光区12形成数个体积较小的柱体33，采用纳米压印技术更容易制作及实现。
本实施例另一种实施方式中，如图9所示，所述电荷阻挡层30包括设于所述遮光区12的第二表面121的数个间隔设置的条形凸起34。具体的，数个所述条形凸起34的排列方式不限定，且均匀分布在所述基层31上，数个条形凸起34均匀设置以保证电荷阻挡层30对负电荷的吸附效果。所述条形起34自身具有电正性特点，所述显示屏组件100外部的负电荷扩散至遮光区12后，数个所述条形凸起34阻挡负电荷扩散并将负电荷吸附外表面，防止负电荷继续扩散至显示区内，且进一步可以对吸附的负电荷固化消除。所述电荷阻挡层30通过纳米压印工艺、转印、光罩工艺或者涂布压印工艺中的一种或多种组合形成。本实施例中，所述凸起通过纳米压印的方式形成，并通过UV光等方式固化。实际上，所述电荷阻挡层30的可以是孔32可以是槽也可以是凸出的结构组成，孔32的截面形状不做限定，凸起的截面形状不做限定，只要可以吸附电荷并阻挡显示屏外部的电荷经过遮光区12进入显示模组即可。
一种实施例中，每两个相邻的所述凸起结构之间的距离大于等于10nm，该距离根据实际需要而选择，以保证可以实现对外部电荷的吸附和阻挡。可以理解为所述电荷阻挡层30的柱体或条形凸起的密度与移动终端外部进入显示屏组件100的电荷大小有相应的变化趋势关系。比如，在显示屏组件100测试过程中可以确定其在使用过程中会产生电荷的量的范围，根据确定的电荷范围来设定所述柱体或者条形凸起的密度来保证可以完全阻挡外部电荷进入显示模组内部；即可以简单理解为，测试确定的电荷越大，对应设置的柱体或者条形凸起的密度越大，这样可以对手机工作中显示屏的有效保护。
一种实施例中，所述所遮光区12的第二表面121上覆盖有中间层(图为示)，所述电 荷阻挡层30形成于所述中间层背向所述第二表面121的一侧，且所述中间层用于将所述电荷阻挡层30固定于所述第二表面121上。所述中间层的材料选用时其与所述遮光区12的油墨层以及所述电荷阻挡层30都有比较好的粘接力，以保证所述电荷阻挡层30可以很稳固定形成在所述遮光区12内，不会发生脱落现象，进而保证电荷阻挡效果。
请参阅图10和图11，本申请提供一种移动终端，具体实施例中以手机为例，所述手机200包括以上所述的显示屏组件100及中框210，所述显示屏组件100装于所述中框210上，所述透明盖板10与所述中框210粘接固定。具体的，所述中框210包括中板2101和位于中板2101两侧的边框2102，所述中板用于制成和承载手机的电池、电路板等其他结构，所述边框用于将显示屏租组件及后壳等外部结构固定密封。所述边框2102包括第二装配边2104和与所述第二装配边2104连接的第三装配边2105，所述第一装配边13与第二装配边2104对接并通过粘胶层40粘接，所述第三装配边2105与部分所述遮光区12对接并通过所述粘胶层40粘接，进而使所述显示屏模组与所述中框210固定连接。所述移动终端采用本申请所述的显示屏组件100，在使用过程中，透明盖板10外部产生的负电荷经过中框210进入显示屏组件100遮光区，由于遮光区设置的电荷阻挡层，可以吸附并消除电荷，进而实现阻挡作用，保证了移动终端的正常显示，进而提升移动终端的质量。
一并参阅图12，本实施例中，所述显示屏组件100的电荷阻挡层30层设于所述第一区122和所述第二区123，也就是整个遮光区12上都有，而延伸区125位于所述电荷阻挡层30外侧。所述第三装配边2105与所述遮光区12的第二区123对接，并通过所述粘胶层40粘接所述第二区123上的电荷阻挡层30与与所述第三装配边2105的表面。
如图13所示，一种实施例中，所述第一区122和所述第二区123上均设有所述电荷阻挡层30，所述第一区122上的电荷阻挡层30的厚度大于所述第二区123上的电荷阻挡层30的厚度。所述粘胶层40粘接所述遮光区12的第二区123与所述第一配合边的表面之间。所述第二区123的电荷阻挡层30厚度较薄，有足够的空间来设置粘胶层40，可以保证显示屏组件100与中框210装配的平整性同时，保证中框210与显示屏组件100粘接位置的密封性能。而且第一区122间隔显示模组20与第二区123，实际上在所述第一装配边13与第二装配边2104之间的粘胶层40进行点胶时，是可以防止液态状态下的胶体经第二区123流入显示屏的显示模组内部的，进而可以保证显示模组20性能。
一种实施例中，所述粘胶层40内掺杂有电正性空穴材料。在不影响所述粘胶层40粘接性能的前提下掺入电正性空穴材料，位于所述第一装配边13与第二装配边2104之间的粘胶层40可以在外部电荷沿透明盖板10的边缘传输时就进行吸附阻挡，辅助位于所述第三装配边2105与部分所述遮光区12之间的电荷阻挡层30共同阻挡外部电荷进入。而位于所述第三装配边2105与部分所述遮光区12之间的粘胶层40上也可以掺入电正性空穴材料。
请参阅图14，一种实施例中，在上述任一实施例中，所述延伸区125上层叠有所述电荷阻挡层30A，所述第一装配边13与第二装配边2104对接，所述粘胶层40粘贴所述延伸区125上的电荷阻挡层30A与所述第二装配边2104。
以上，仅为本申请的部分实施例和实施方式，本申请的保护范围不局限于此，任何熟知本领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以权利要求的保护范围为准。
