附图说明 为了更清楚地说明本发明实施例或现有技术中的技术方案， 下面将对实 施例或现有技术描述中所需要使用的附图作简单地介绍， 显而易见地， 下面 描述中的附图仅仅是本发明的一些实施例， 对于本领域普通技术人员来讲， 在不付出创造性劳动的前提下， 还可以根据这些附图获得其他的附图。
图 1是现有内嵌式触控阵列基板面板电路结构示意图。
图 2是本发明实施例内嵌式触控阵列基板结构示意图。
图 3是本发明实施例内嵌式触控阵列基板局部结构示意图。
具体实施方式
以下各实施例的说明是参考附图， 用以示例本发明可以用以实施的特定 实施例。 本发明所提到的方向和位置用语， 例如「上」、 「中」、 「下」、 「前」、 r后」、 「左」、 「右」、 「内」、 「夕卜」、 「侧面」等， 仅是参考附加图式的方向和 位置。 因此， 使用的方向和位置用语是用以说明及理解本发明， 而非用以限 制本发明。
请参照图 2所示，本发明实施例一提供一种内嵌式触控阵列基板，包括： 交错排列的若干对栅扫描线和数据线；
分别与相邻的栅扫描线及数据线电连接的像素开关；
与像素开关电连接的像素电极；
设置在相邻两对栅扫描线之间的触控发射线；
设置在相邻两对数据线之间且与触控发射线相交的触控接收线； 以及 电连接在触控发射线与触控接收线相交处的触控单元。
本实施例的栅扫描线和数据线均采用双走线，给触控发射线及触控接收 线提供独立的走线空间， 进而降低面板驱动信号与触控信号之间的干扰， 提 高触控灵敏度， 同时减小信号幅度， 降低面板功耗。
具体的， 本实施例的若干对栅扫描线中， 每一对均包括平行相邻的第一 栅扫描线 11和第二栅扫描线 12, 若干对数据线中， 每一对均包括平行相邻 的第一数据线 21和第二数据线 22。相邻两对栅扫描线的间距 D远大于每对 栅扫描线中两栅扫描线的间距 d, 即第一栅扫描线 11和第二栅扫描线 12的 间距 d较小， 而相邻两对栅扫描线的间距 D较大， 以便给触控发射线 3提供 足够的走线空间； 同样地， 相邻两对数据线的间距 W远大于每对数据线中 两数据线的间距 w, 即第一数据线 21和第二数据线 22的间距 w较小， 而相 邻两对数据线的间距 W较大， 以便给触控接收线 4提供足够的走线空间。
在触控发射线 3与触控接收线 4相交处的触控单元包括第一触点 31和 第二触点 41 ,其中第一触点 31电连接在触控发射线 3上， 第二触点 41电连 接在触控接收线 4上。
再请参照图 3所示， 为图 2的局部结构示意图， 用以说明本实施例的栅 扫描线和数据线均采用双走线时，像素单元（包括像素开关 5和像素电极 6 ) 与栅扫描线和数据线的连接关系。 第一栅扫描线 11和第二栅扫描线 12, 与 第一数据线 21和第二数据线 22彼此交错形成 "井" 字形结构， 其中， 第一 栅扫描线 11位于第二栅扫描线 12上方， 第一数据线 21位于第二数据线 22 右侧。 第一像素开关 51分别电连接在第一栅扫描线 11和第一数据线 21上， 第一像素电极 61与第一像素开关 51电连接； 第二像素开关 52分别电连接 在第一栅扫描线 11和第二数据线 22上， 第二像素电极 62与第二像素开关 52电连接； 第三像素开关 53分别电连接在第二栅扫描线 12和第二数据线 22上， 第三像素电极 63与第三像素开关 53电连接； 第四像素开关 54分别 电连接在第二栅扫描线 12和第一数据线 21上， 第四像素电极 64与第四像 素开关 54电连接。 也就是说， 电连接在第一栅扫描线 11上的像素开关 51、 52和像素电极 61、 62, 与电连接在第二栅扫描线 12上的像素开关 53、 54 和像素电极 63、 64分别相对称； 电连接在第一数据线 21上的像素开关 51、 54和像素电极 61、 64, 与电连接在第二数据线 22上的像素开关 52、 53和 像素电极 62、 63分别相对称。
本实施例中， 像素开关 5为薄膜场效应晶体管 （TFT )。
此外， 由于图 1所示现有内嵌式触控阵列基板结构中， 触控发射线 y 采用栅扫描线 1' 之外的工艺膜层完成， 触控发射线 4' 采用数据线 2' 之外 的工艺膜层完成， 工艺复杂， 成本较高， 因此本实施例中， 触控发射线 3与 栅扫描线 11、 12采用同一层金属构图 （patterning ), 触控接收线 4与数据线 21、 22采用同一层金属构图， 从而简化工艺， 降低成本。
应当说明的是， 本实施例的内嵌式触控阵列基板一方面由于栅扫描线和 数据线均采用双走线， 相对于单走线可以连接更多的像素开关和像素电极， 扩大显示区域； 另一方面由于给体现触控功能的触控发射线及触控接收线提 供了独立的走线空间， 进而降低了面板驱动信号与触控信号之间的干扰， 提 高了触控灵敏度， 因此尤其适用于大尺寸的带有触控功能的液晶显示面板。
相应于本发明实施例一的内嵌式触控阵列基板， 本发明实施例二提供一 种液晶显示面板， 包括：
内嵌式触控阵列基板；
彩色滤光片基板， 与所述内嵌式触控阵列基板相对； 以及
液晶层， 配置于所述内嵌式触控阵列基板与所述彩色滤光片基板之间； 其中， 所述内嵌式触控阵列基板包括：
交错排列的若干对栅扫描线和数据线；
分别与相邻的栅扫描线及数据线电连接的像素开关；
与像素开关电连接的像素电极；
设置在相邻两对栅扫描线之间的触控发射线；
设置在相邻两对数据线之间且与触控发射线相交的触控接收线； 以及 电连接在触控发射线与触控接收线相交处的触控单元。
有关本实施例中内嵌式触控阵列基板的具体结构及相应技术效果请参 照本发明实施例一的说明及图 1-3所示， 此处不再贅述。
以上所揭露的仅为本发明较佳实施例而已， 当然不能以此来限定本发明 之权利范围， 因此依本发明权利要求所作的等同变化， 仍属本发明所涵盖的 范围。
