 本发明的实施方式
为让本发明上述目的、特征及优点更明显易懂，下文特举本发明较佳实施例，并配合附图，作详细说明如下。再者，本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。
请参考图1至图4所示，图1是本发明一实施例的窄边框触摸显示器的剖面示意图，图2是本发明一实施例的窄边框触摸显示器的平面示意图，图3是本发明一实施例的窄边框触摸显示器进行弯折工艺前的剖面示意图，图4是本发明一实施例的窄边框触摸显示器进行弯折工艺前的平面示意图。所述窄边框触摸显示器主要包含一显示层1及一自电容式触控层3。
所述显示层1可以是一柔性显示面板，例如其可以是一有机发光二极体显示面板，包括多个有机发光二极体元件。所述显示层1具有相对的第一表面与第二表面。
如图1及图3所示，所述自电容式触控层3是设置于所述显示层1的第一表面上，并包括一触控区301及位于触控区301一侧的接线区300。所述触控区301设有多个触控电极30，且每一所述触控电极30连接一引线31，所述引线31的一末端310延伸至所述接线区300。如图1所示，所述自电容式触控层3位于所述接线区300的部分延伸超出所述显示层1的边缘并通过弯折工艺而设置于所述显示层1的第二表面上，使得所述引线31的末端310被配置成与所述触控电极30相背对。
请参考图2及图4，所述多个触控电极30优选是呈矩阵排列，可分成数列及数行。在一实施例中，在每一列触控电极30所连接的引线31共同于同一侧延伸至所述接线区300。在一实施例中，所述触控电极30及引线31是由透明导电材料构成的，例如所述透明导电材料可以为氧化铟锡。在一实施例中，每一所述触控电极30可以是呈矩形。
所述自电容式触控层3的结构中，所述多个触控电极30皆位于同一层并且各自连接一条引线31。因此只需要一道光罩工艺即可同时完成触控电极30与引线31的制作，并不需要额外的架桥结构，故所述窄边框触摸显示器的制作工艺较为简单，成本较低廉。
再者，相较于传统基于互电容感应原理制作的触摸屏，所述自电容式触控层3在接线区300存在较多的引线，占据了有效触控电极位置，导致该区域的触控灵敏性较差，成为触摸显示器的触摸盲区。因此，本发明通过上述的弯折(Bending)工艺将所述自电容式触控层3延伸超出所述显示层1边缘的接线区300的部分弯折至显示层1的背面，从而保证所述自电容式触控层3在所述显示层1上能提供全面有效的触摸感应区域，有效提高触摸感应的屏占比。
如图1和图3所示，所述窄边框触摸显示器可进一步包含至少一偏光片2及一柔性印刷电路板4。所述至少一偏光片2可设置于所述自电容式触控层3上，对应覆盖所述触控区301及所述显示层1的一显示区。所述柔性印刷电路板4可设置于所述自电容式触控层3的接线区300并连接所述引线31。所述柔性印刷电路板4可设有触控芯片或连接至一外部的触控电路，以将所述自电容式触控层3感应的触控信号传递至所述触控芯片，进而依据所述触控信号判断一触摸位置。
在另一实施例中，每一所述触控电极30可以是呈锯齿形，以增加触控准确率。
例如，请进一步参考图5所示，在一优选实施例中，所述多个触控电极分成数列，其中在每一列触控电极中，每三个触控电极构成一Y轴感应群33。具体而言，在每一Y轴座标感应群33中，包括间隔配置的一第一触控电极30A、一第二触控电极30C及一第三触控电极30B。所述第一触控电极30A具有数个下锯齿部300a。所述第二触控电极30C具有数个上锯齿部300c。所述第三触控电极30B位于所述第一触控电极30A与所述第二触控电极30C之间，且具有数个上锯齿部300b与数个下锯齿部301b。值得注意的是，如图5所示，所述第三触控电极30B的上锯齿部300b面向所述第一触控电极30A且形状对应所述第一触控电极30A的下锯齿部300a；所述第三触控电极30B的下锯齿部301b面向所述第二触控电极30C且形状对应所述第二触控电极30C的上锯齿部300c。通过上述触控电极构成的Y轴感应群33，可以缩短触控电极30在列方向上占据的空间，让所述窄边框触摸显示器在列方向能够设置更多触控电极30。
通过上述Y轴感应群33的感应结构，使用者手指与锯齿状的触控电极之间的感应面积在手指移动时会不断变化，这样可以通过感应面积（敏感度）的比例来计算手指的Y坐标位置，提高Y坐标的触控精度。
综上所述，相较于现有技术，本发明主要是通过在显示层上设置一自电容式触控层，让所述自电容式触控层的触控电极的引线延伸汇集至一侧的接线区，并且使所述自电容式触控层位于所述接线区的部分通过弯折而设置于所述显示层的背面。自电容式触控层的触控电极和引线不需要额外的架桥结构，仅需要一道光罩工艺，故本发明的窄边框触摸显示器制作工艺较为简单，且成本较低，并且还可以有效减小下边框非显示区面积，提供更高的屏占比。
本发明已由上述相关实施例加以描述，然而上述实施例仅为实施本发明的范例。必需指出的是，已公开的实施例并未限制本发明的范围。相反地，包含于权利要求书的精神及范围的修改及均等设置均包括于本发明的范围内。
