现结合具体实施例对本申请的技术方案进行描述。
本申请提供了一种显示面板1，如图1至图4所示，包括显示区100和与所述显示区100相邻的非显示区200，所述显示面板1包括相对设置的第一基板11和第二基板12，所述第一基板11与所述第二基板12之间设有位于所述非显示区200内的第一窄边框胶13、及位于所述显示区100内的液晶层14，所述第一窄边框胶13至少一侧设有第一反光层15。
可以理解的是，随着显示技术的发展，在诸如显示面板等由上下基板结合框胶封装的成盒结构中，框胶固化一般采用在显示面板侧向对框胶进行光照固化的方式，但受限于光照强度以及显示面板中位于框胶上下侧诸如黑色挡墙等结构对光线的反射率较低等因素，使得框胶的固化率和固化深度不足，导致需要较大的框胶宽度以保证上下基板的粘接成盒，变向增加了诸如显示面板等成盒结构的边框宽度；本实施例中，通过在第一窄边框胶13至少一侧设至第一反光层15，便于在对第一窄边框胶13进行光照固化时，通过第一反光层15对光线的反射，增加光线的穿透深度，从而提高了第一窄边框胶13的固化深度，提高了第一窄边框胶13整体的固化率，便于使用较小宽度的第一窄边框胶13实现显示面板1的成盒；实现了诸如显示面板1等成盒结构的窄边框化。
承上，本实施例中，如图1所示，所述第一窄边框胶13两侧均设有第一反光层15，显然，将所述第一窄边框胶13两侧均设置所述第一反光层15，使得在采用诸如紫外光源侧向对所述第一窄边框胶13进行光照固化的过程中，光线在上下两所述第一反光层15之间多次反射，不仅提高了光线在所述第一窄边框胶13内的行程，提高了所述第一窄边框胶13的固化深度，而且增加了所述第一窄边框胶13的单位面积内光照的饱和度，提高了所述第一窄边框胶13的固化效率；其中，所述第一反光层15可以为诸如金属等多种反光材料，具体的，所述第一反光层15的材料可以是铜，铝，钼等金属材料，显然，当所述第一反光层15的材料为铝时，所述第一反光层15在光线波长为300nm到400nm的波段内，反射率可达90%。
在一实施例中，如图2至图4所示，所述第一反光层15包括第一反光图案151，所述第一反光图案151远离所述显示区100一侧的面积大于所述第一反光图案151靠近所述显示区100一侧的面积；可以理解的是，所述第一反光层15可以图案化形成第一反光图案151，通过第一反光图案151实现对特定区域的光线进行反射，精细化的控制各处的反射量，也避免整面设置所述第一反光层15后，所述第一窄边框胶13仅与所述第一反光层15粘接，使得所述第一窄边框胶13既与所述第一反光层15粘接，又可以穿过图案化的所述第一反光层15的镂空位置与所述第一基板11或所述第二基板12粘接，使得所述第一基板11与所述第二基板12成盒更为牢固；此外，所述第一反光图案151远离所述显示区100一侧的面积大于所述第一反光图案151靠近所述显示区100一侧的面积，使得所述第一反光图案151远离所述显示区100的一侧相比于靠近所述显示区100的一侧具备较强的光线反射能力，便于将刚入射进入所述第一窄边框胶13的具备较强光强的光线进行更多的反射，并且，可以理解的是，所述第一反光图案151远靠近所述显示区100的一侧，也即是所述第一反光图案151远离紫外光源的一侧，显然该侧受到的光线照射强度较弱，在此处可以相对降低所述第一反光图案151的面积，产生更大的镂空位置便于所述第一窄边框胶13与所述第一基板11或所述第二基板12粘接。
在一实施例中，如图2至图4所示，所述第一反光图案151包括至少一圈绕所述显示区100设置的多个第一反光体1511；其中
当所述第一反光图案151包括一圈所述第一反光体1511时，所述第一反光体1511远离所述显示区100一侧的面积大于所述第一反光体1511靠近所述显示区100一侧的面积；
当所述第一反光图案151包括至少两圈所述第一反光体1511时，相邻两圈所述第一反光体1511中，远离所述显示区100一侧的一圈所述第一反光体1511的面积大于靠近所述显示区100一侧的另一圈所述第一反光体1511的面积。
可以理解的是，所述第一反光体1511的形状可以规则图形或者不规则图形，其中可以是椭圆形、梯形、三角形、圆形或矩形等形状，具体的，如图2所示，当所述第一反光图案151包括一圈所述第一反光体1511时，所述第一反光体1511可以是三角形或梯形等形状，以使得所述第一反光体1511远离所述显示区100一侧的面积大于所述第一反光体1511靠近所述显示区100一侧的面积；例如，所述第一反光体1511形状为梯形，此时，所述第一反光体1511较短的上底边位于所述第一反光体1511靠近所述显示区100一侧，所述第一反光体1511较长的下底边位于所述第一反光体1511远离所述显示区100一侧，使得所述第一反光体1511远离所述显示区100一侧的面积大于所述第一反光体1511靠近所述显示区100一侧的面积；如图3所示，当所述第一反光图案151包括至少两圈所述第一反光体1511时，可以通过使相邻两圈所述第一反光体1511中，远离所述显示区100一侧的一圈所述第一反光体1511中的各所述第一反光体1511面积大于靠近所述显示区100一侧的另一圈所述第一反光体1511中的各所述第一反光体1511的面积；如图4所示，也可以使远离所述显示区100一侧的一圈所述第一反光体1511的排列密度大于靠近所述显示区100一侧的另一圈所述第一反光体1511的排列密度，最终使得相邻两圈所述第一反光体1511中，远离所述显示区100一侧的一圈所述第一反光体1511的面积大于靠近所述显示区100一侧的另一圈所述第一反光体1511的面积。
在一实施例中，如图1所示，所述第一反光层15远离所述第一窄边框胶13的一侧设有第一黑色挡墙16；可以理解的是，在所述显示面板1中，诸如所述第一黑色挡墙16等结构对光线的反射率几乎为零，极容易吸收光线，降低了固化所述第一窄边框胶13的光线的光强，本实施例中，将所述第一反光层15设置于所述第一黑色挡墙16与所述第一窄边框胶13之间，很大程度的减少了所述第一黑色挡墙16对光线的吸收；本实施例中，当所述第一窄边框胶13只有一侧设有所述第一反光层15时，具体可以将所述第一反光层15设置于所述第一窄边框胶13靠近所述第一黑色挡墙16的一侧。
在本申请所提供的触控显示装置中，如图5所示，包括触控面板2和如前所述的显示面板1，所述显示面板1与所述触控面板2之间设有位于所述非显示区200内的第二窄边框胶31，所述第二窄边框胶31至少一侧设有第二反光层32。
可以理解的是，目前，触控显示屏中显示面板与触控面板均采用框贴的形式对合，在显示面板与触控面板之间涂布框胶然后固化成盒，显然，在框胶侧固化的过程中，由于显示面板和触控面板靠近框胶的部分为诸如玻璃基板等透明或半透明结构，对固化框胶的光线反射率较低，使得框胶的固化率和固化深度不足，从而也导致了连接显示面板和触控面板的需要更大的宽度的框胶，以增加粘接面积，增加了触控显示屏的边框宽度；本实施例中，通过在第二窄边框胶31至少一侧设至第二反光层32，便于在对第二窄边框胶31进行光照固化时，通过第二反光层32对光线的反射，增加光线的穿透深度，从而提高了第二窄边框胶31的固化深度，提高了第二窄边框胶31整体的固化率，便于使用较小宽度的第二窄边框胶31实现触控显示装置的成盒；实现了触控显示装置的窄边框化。
承上，本实施例中，如图5所示，所述第二窄边框胶31两侧均设有第二反光层32，显然，将所述第二窄边框胶31两侧均设置所述第二反光层32，使得在采用诸如紫外光源侧向对所述第二窄边框胶31进行光照固化的过程中，光线在上下两所述第二反光层32之间多次反射，不仅提高了光线在所述第二窄边框胶31内的行程，提高了所述第二窄边框胶31的固化深度，而且增加了所述第二窄边框胶31的单位面积内光照的饱和度，提高了所述第二窄边框胶31的固化效率；其中，所述第二反光层32的材料可以与所述第一反光层15的材料相同，在此不再赘述。
在一实施例中，如图6至图8所示，所述第二反光层32包括第二反光图案321，所述第二反光图案321远离所述显示区100一侧的面积大于所述第二反光图案321靠近所述显示区100一侧的面积；可以理解的是，所述第二反光层32可以图案化形成第二反光图案321，通过第二反光图案321与所述第一反光图案151产生类似的效果，不仅使得所述第二反光图案321远离所述显示区100的一侧相比于靠近所述显示区100的一侧具备较强的光线反射能力，便于将刚入射进入所述第二窄边框胶31的具备较强光强的光线进行更多的反射，并且，使所述第一反光图案151远靠近所述显示区100的一侧相对具备较低的反射面积，产生更大的镂空位置便于所述第二窄边框胶31与所述显示面板1或所述触控面板2粘接。
在一实施例中，如图6至图8所示，所述第二反光图案321包括至少一圈绕所述显示区100设置的多个第二反光体3211；其中
当所述第二反光图案321包括一圈所述第二反光体3211时，所述第二反光体3211远离所述显示区100一侧的面积大于所述第二反光体3211靠近所述显示区100一侧的面积；
当所述第二反光图案321包括至少两圈所述第二反光体3211时，相邻两圈所述第二反光体3211中，远离所述显示区100一侧的一圈所述第二反光体3211的面积大于靠近所述显示区100一侧的另一圈所述第二反光体3211的面积。
可以理解的是，所述第二反光体3211可以与所述第一反光体1511具备相同的形状选择，在此不再赘述；具体的，如图6所示，当所述第二反光图案321包括一圈所述第二反光体3211时，所述第二反光体3211也可以是三角形或梯形等形状，以使得所述第二反光体3211远离所述显示区100一侧的面积大于所述第二反光体3211靠近所述显示区100一侧的面积；例如，所述第二反光体3211形状为梯形，此时，所述第二反光体3211较短的上底边位于所述第二反光体3211靠近所述显示区100一侧，所述第二反光体3211较长的下底边位于所述第二反光体3211远离所述显示区100一侧，使得所述第二反光体3211远离所述显示区100一侧的面积大于所述第二反光体3211靠近所述显示区100一侧的面积；如图7所示，当所述第二反光图案321包括至少两圈所述第二反光体3211时，可以通过使相邻两圈所述第二反光体3211中，远离所述显示区100一侧的一圈所述第二反光体3211中的各所述第二反光体3211面积大于靠近所述显示区100一侧的另一圈所述第二反光体3211中的各所述第二反光体3211的面积；如图8所示，也可以使远离所述显示区100一侧的一圈所述第二反光体3211的排列密度大于靠近所述显示区100一侧的另一圈所述第二反光体3211的排列密度，最终使得相邻两圈所述第二反光体3211中，远离所述显示区100一侧的一圈所述第二反光体3211的面积大于靠近所述显示区100一侧的另一圈所述第二反光体3211的面积。
在一实施例中，如图5所示，所述触控面板2包括相对设置的封装盖板21和触控基板22，所述封装盖板21与所述触控基板22之间设有位于所述非显示区200内的第三窄边框胶23，所述第三窄边框胶23至少一侧设有第三反光层24。
可以理解的是，目前，触控面板在非显示区处也会设置黑色挡墙等遮光结构，参考前述黑色挡墙反射率较低的问题，同样会产生触控面板中的框胶在侧固化时固化率和固化深度不足的问题，在此不再赘述，本实施例中，通过在第三窄边框胶23至少一侧设至第三反光层24，便于在对第三窄边框胶23进行光照固化时，通过第三反光层24对光线的反射，增加光线的穿透深度，从而提高了第三窄边框胶23的固化深度，提高了第三窄边框胶23整体的固化率，便于使用较小宽度的第三窄边框胶23实现触控面板2的成盒；使得所述显示面板1、触控面板2以及位于所述显示面板1与所述触控面板2之间的部分均具备窄边框结构，整体实现了所述触控显示装置的窄边框化。
承上，本实施例中，如图5所示，所述第三窄边框胶23两侧均设有第三反光层24，显然，将所述第三窄边框胶23两侧均设置所述第三反光层24，使得在采用诸如紫外光源侧向对所述第三窄边框胶23进行光照固化的过程中，光线在上下两所述第三反光层24之间多次反射，不仅提高了光线在所述第三窄边框胶23内的行程，提高了所述第三窄边框胶23的固化深度，而且增加了所述第三窄边框胶23的单位面积内光照的饱和度，提高了所述第三窄边框胶23的固化效率；其中，所述第三反光层24的材料可以与所述第一反光层15或所述第二反光层32的材料相同，在此不再赘述。
值得注意的是，现有触控显示屏主要由显示面板和具备保护盖板的触控面板组成，其中，保护盖板由于受到物理强化的限制，厚度至少大于3.0mm，远大于诸如液晶面板等显示面板的厚度，除保护盖板外，触控面板还包括触控基板和粘接保护盖板与触控基板的光学胶层，进一步加大显示面板与触控面板的厚度差，在将显示面板与触控面板进行真空框贴时，会使厚度较薄的显示面板向触控基板弯曲靠拢变形，此外，触控面板也会由于设置在保护盖板与触控基板之间整面性的光学胶而弯曲受限；本实施例中，将所述封装盖板21与所述触控基板22通过第三窄边框胶23粘合，使触控面板2形成与显示面板1相似的成盒结构，也解决了采用整面性光学胶粘合结构导致触控面板2弯曲受限的问题；此外，显然触控面板2的厚度越薄越容易折弯，而采用成盒结构的触控面板2也可大幅降低触控面板2的厚度，避免真空框贴时显示面板1向触控基板22方向过度弯曲而变形。
综上，本实施例中，将所述封装盖板21与所述触控基板22通过位于所述非显示区200内的第三窄边框胶23粘合，并在所述第三窄边框胶23至少一侧设置所述第三反光层24，不仅实现了所述触控面板2的窄边框化，而且采用成盒结构的触控面板2还可大幅降低触控面板2的厚度，避免框贴时显示面板1向触控基板22方向过度弯曲而变形。
在一实施例中，如图9至图11所示，所述第三反光层24包括第三反光图案241，所述第三反光图案241远离所述显示区100一侧的面积大于所述第三反光图案241靠近所述显示区100一侧的面积；可以理解的是，所述第三反光层24可以图案化形成第三反光图案241，通过第三反光图案241与所述第一反光图案151或所述第二反光图案321产生类似的效果，不仅使得所述第三反光图案241远离所述显示区100的一侧相比于靠近所述显示区100的一侧具备较强的光线反射能力，便于将刚入射进入所述第三窄边框胶23的具备较强光强的光线进行更多的反射，并且，使所述第三反光图案241远靠近所述显示区100的一侧相对具备较低的反射面积，产生更大的镂空位置便于所述第三窄边框胶23与所述封装盖板21或所述触控基板22粘接。
在一实施例中，如图9至图11所示，所述第三反光图案241包括至少一圈绕所述显示区100设置的多个第三反光体2411；其中
当所述第三反光图案241包括一圈所述第三反光体2411时，所述第三反光体2411远离所述显示区100一侧的面积大于所述第三反光体2411靠近所述显示区100一侧的面积；
当所述第三反光图案241包括至少两圈所述第三反光体2411时，相邻两圈所述第三反光体2411中，远离所述显示区100一侧的一圈所述第三反光体2411的面积大于靠近所述显示区100一侧的另一圈所述第三反光体2411的面积。
可以理解的是，所述第三反光体2411可以与所述第一反光体1511或所述第二反光体3211具备相同的形状选择，在此不再赘述；具体的，如图9所示，当所述第三反光图案241包括一圈所述第三反光体2411时，所述第三反光体2411也可以是三角形或梯形等形状，以使得所述第三反光体2411远离所述显示区100一侧的面积大于所述第三反光体2411靠近所述显示区100一侧的面积；例如，所述第三反光体2411形状为梯形，此时，所述第三反光体2411较短的上底边位于所述第三反光体2411靠近所述显示区100一侧，所述第三反光体2411较长的下底边位于所述第三反光体2411远离所述显示区100一侧，使得所述第三反光体2411远离所述显示区100一侧的面积大于所述第三反光体2411靠近所述显示区100一侧的面积；如图10所示，当所述第三反光图案241包括至少两圈所述第三反光体2411时，可以通过使相邻两圈所述第三反光体2411中，远离所述显示区100一侧的一圈所述第三反光体2411中的各所述第三反光体2411面积大于靠近所述显示区100一侧的另一圈所述第三反光体2411中的各所述第三反光体2411的面积；如图11所示，也可以使远离所述显示区100一侧的一圈所述第三反光体2411的排列密度大于靠近所述显示区100一侧的另一圈所述第三反光体2411的排列密度，最终使得相邻两圈所述第三反光体2411中，远离所述显示区100一侧的一圈所述第三反光体2411的面积大于靠近所述显示区100一侧的另一圈所述第三反光体2411的面积。
在一实施例中，如图5所示，所述第三反光层24远离所述第三窄边框胶23的一侧设有第二黑色挡墙25；可以理解的是，在所述触控面板2中，诸如所述第二黑色挡墙25等结构对光线的反射率几乎为零，极容易吸收光线，防降低固化所述第三窄边框胶23的光线的光强，本实施例中，将所述第三反光层24设置于所述第二黑色挡墙25与所述第三窄边框胶23之间，很大程度的减少了所述第二黑色挡墙25对光线的吸收；具体的，当所述第三窄边框胶23只有一侧设有所述第三反光层24时，可以将所述第三反光层24设置于所述第三窄边框胶23靠近所述第二黑色挡墙25的一侧。
本申请还提供一种触控显示装置的制作方法，如图13所示，包括以下步骤：
步骤S100：提供一触控面板2和一显示面板1，所述显示面板1包括显示区100和与所述显示区100相邻的非显示区200；
步骤S200：在所述触控面板2和/或所述显示面板1上形成位于所述非显示区200内的第二反光层32，在所述第二反光层32上形成位于所述触控面板2与所述显示面板1之间的第二窄边框胶31；及
步骤S300：将所述触控面板2与所述显示面板1对合，采用侧边光照的方式将所述第二窄边框胶31固化。
可以理解的是，位于所述非显示区200内的所述第二反光层32，既可以形成于所述触控面板2上，又可以形成于所述显示面板1上，或者形成于所述显示面板1和所述触控面板2上，具体可以采用蒸镀、气相沉积等多种方式，具体采用侧边光照的方式将所述第二窄边框胶31固化的过程中，可以采用前述紫外光源照射，由于提前对所述第二反光层32的制作，便于对固化所述第二窄边框胶31的光线的反射，提高了固化深度和固化效率，具体侧向固化的方法均为较成熟工艺，在此不再赘述。
在一实施例中，如图14所示，所述提供一显示面板1包括：
步骤S111：提供一第一基板11和一第二基板12；
步骤S112：在所述第一基板11和/或所述第二基板12上形成位于所述非显示区200内的第一反光层15，在所述第一反光层15上形成位于第一基板11与所述第二基板12之间的第一窄边框胶13；及
步骤S113：将所述第一基板11与所述第二基板12对合，采用侧边光照的方式将所述第一窄边框胶13固化。
在一实施例中，如图14所示，所述提供一触控面板2包括：
步骤S121：提供一封装盖板21和一触控基板22；
步骤S122：在所述封装盖板21和/或所述触控基板22上形成位于所述非显示区200内的第三反光层24，在所述第三反光层24上形成位于封装盖板21与所述触控基板22之间的第三窄边框胶23；及
步骤S123：将所述封装盖板21与所述触控基板22对合，采用侧边光照的方式将所述第三窄边框胶23固化。
显然，如前所述，具体采用侧边光照的方式将所述第一窄边框胶13固化和采用侧边光照的方式将所述第三窄边框胶23固化，由于所述第一反光层15和所述第三反光层24的制作，分别提高了所述第一窄边框胶13和第三窄边框胶23的固化深度和固化效率；在此不再赘述。
值得注意的是，如图15所示，所述触控显示装置的制作方法还可以包括以下步骤：
步骤S400：将所述触控面板2和所述显示面板1折弯，以使所述显示面板1弯曲呈弧型曲面结构，所述触控面板2设置于呈弧型的所述显示面板1内凹的一侧且与所述触控面板2的形状相适应。
可以理解的是，如图12所示，将所述触控面板2和所述显示面板1进框贴后，还包括一折弯步骤，在折弯过程中，由于所述触控面板2的成盒结构，降低了所述触控面板2的厚度，也避免原有整面性光学胶限制折弯的结构，从而便于所述触控显示装置折弯形成曲面触控显示屏。
综上所述，本申请通过在第一窄边框胶13至少一侧设至第一反光层15，便于在对第一窄边框胶13进行光照固化时，通过第一反光层15对光线的反射，增加了光线的穿透深度，从而提高了第一窄边框胶13的固化深度，提高了第一窄边框胶13整体的固化率，便于使用较小宽度的第一窄边框胶13实现显示面板1的成盒；实现了诸如显示面板1等成盒结构的窄边框化，本申请的触控显示装置中，通过在位于显示面板1与触控面板2之间的第二窄边框胶31至少一侧设至第二反光层32，实现了触控显示装置整体的窄边框化，并且，此种结构制作工艺成熟，方法简单，框胶固化效率高，便于窄边框触控显示装置的制作。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
