参阅图1,为本申请提供的一种彩膜基板的结构示意图。在一种实施例中,所述彩膜基板1包括:第一衬底基板11、色阻层12(图中未示出)、黑矩阵124以及第一偏光片13,所述第一偏光片13中设置有上转换发光材料层136,所述上转换发光材料层136在红外激光的照射下,形成激光笔的可视激光点,增大了所述彩膜基板1的可视角度。所述色阻层12为:红色色阻层121/蓝色色阻层122/绿色色阻层123或是红色色阻层121/蓝色色阻层122/绿色色阻层123/白色色阻层(图中未示出),不限于附图1中所示的红色色阻层121/蓝色色阻层122/绿色色阻层123。
进一步地,所述上转换发光材料层136分为:上转换红光材料和上转换绿光材料;所述上转换发光材料可阻止光线被吸收,尤其是能量低于可见光能量的红外光,红外光为非可见光,当激光笔发出的近红外光照射在液晶显示面板上时,在激光笔和液晶显示面板之间不会产生光束干扰显示区域的显示效果。因此,所述上转换红光材料和所述上转换绿光材料对红外激光的波长均具有一定的预设波长长度。所述上转换红光材料的预设波长长度为:960nm;所述上转换绿光材料的预设波长长度为:966nm。
进一步地,所述上转换红光材料采用掺杂有敏化离子为Tm3+或Yb3+的BaY2F8晶体;所述上转换绿光材料采用掺杂有敏化离子为Er3+的ZnWO3晶体。由于所述上转换发光材料层136的厚度对所述彩膜基板1具有一定的影响,即若所述上转换发光材料层136过厚会影响所述彩膜基板1的偏光效果,也影响了所述彩膜基板1的轻薄化;若所述上转换发光材料层136过薄,又会无法发挥所述上转换发光材料层136对红外激光的反射效果。因此,所述上转换发光材料层136还具备一定的预设厚度,所述上转换发光材料层136的预设厚度为:4um-8um。
进一步地,所述第一偏光片13由:离型膜131、压敏胶(PSA,Pressure Sensitive Adhesive)132、第一三醋酸纤维薄膜(TAC,Triacetyl Cellulose)133、聚乙烯醇膜(PVA,Polyvinyl Alcohol)134、第二三醋酸纤维薄膜135、上转换发光材料层136、聚对苯二甲酸乙二醇酯膜(PET,Polyethylene Terephthalate)137以及散射粒子138依次层叠组成,由于所述散射粒子138覆盖在所述聚对苯二甲酸乙二醇酯膜137背离所述上转换发光材料层136的一侧,当出射光线经过所述第一偏光片13时,激光笔的可视性被增强,因此,所述彩膜基板1的显示质量被提升。所述第二偏光片(图中未示出)由压敏胶、第一三醋酸纤维薄膜、聚乙烯醇膜、第二三醋酸纤维薄膜、聚对苯二甲酸乙二醇酯膜以及散射粒子依次层叠组成,详见图3。
具体地,所述离型膜131主要是为了隔离、保护所述压敏胶132;所述压敏胶132是一类对压力有敏感性的胶粘剂且耐高温、防潮,还可以在所述压敏胶132中添加阻止紫外线通过的成份,制成防紫外线的偏光片;所述聚乙烯醇膜134是偏光片的核心层,主要起到偏振的作用,低粘性,但是所述聚乙烯醇膜134极易水解,经过延伸处理后在温热的环境中会很快变形、收缩、松弛、衰退,强度低,质脆易破,不便于使用和加工,因此,一方面为了保护偏光片13的物理特性,另一方面则可防止所述聚乙烯醇膜134的回缩,在所述聚乙烯醇膜134的两侧各复合一层具有高光透过率、耐水氧性好又有一定机械强度的三醋酸纤维薄膜(133、135),即所述第一三醋酸纤维薄膜133和所述第二三醋酸纤维薄膜135,以保护所述聚乙烯醇膜134。此外,在一种实施例中,还可以在所述压敏胶132、所述三醋酸纤维薄膜(133、135)或是所述聚乙烯醇膜134上着色可形成彩色偏光片以替代所述色阻层12。
进一步地,根据用户的其他使用需求,所述第一偏光片13背离所述散射粒子138的一侧还可以设置透射膜、反射膜或是半透半反膜,以形成透射偏光片、反射偏光片或是半透半反偏光片。
参阅图2,在本申请的另一种实施例中,所述彩膜基板1’包括:色阻层12’、黑矩阵124’、第二偏光片13’以及第二衬底基板11’,所述第二衬底基板11’中设置有所述上转换发光材料层112’,所述上转换发光材料层112’在红外激光的照射下,形成激光笔的可视激光点,增大了所述彩膜基板1的可视角度。
进一步地,所述第二衬底基板11’由衬底基板111’和所述上转换发光材料层112’组成,所述上转换发光材料层112’具备上述所述的所有的上转换发光材料层112’的特点。
本申请还提供一种液晶显示面板,包括上述所述的所有的彩膜基板1的特点,正对于所述彩膜基板’设置的阵列基板3以及设置在所述彩膜基板1与所述阵列基板3之间的液晶层2。所述液晶层2内设置有若干个液晶子21。
参阅图4,本申请还提供一种彩膜基板的制作方法,该方法包括下述步骤:S10,提供第一衬底基板或是第二衬底基板;S20,若采用所述第二衬底基板,则在所述第二衬底基板上沉积上转换发光材料层;S30,在所述第一衬底基板和/或所述第二衬底基板一侧沉积色阻层、黑矩阵;S40,在所述第一衬底基板和/或所述第二衬底基板靠近所述色阻层的一侧贴附第一偏光片或是第二偏光片;S50,若是所述第一偏光片,则在所述第一偏光片背离所述衬底基板的一侧沉积上转换发光材料层。其中,上述步骤“S20”和步骤“S50”中沉积所述上转换发光材料层采用旋涂工艺。
以上对本申请实施例所提供的一种彩膜基板、液晶显示面板以及彩膜基板的制作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。
