现有技术中是通过在感测线和驱动线的外侧设置一接地线,来解决噪声的干扰问题,而本发明用金属外壳替换所述接地线,可直接在氧化铟锡薄膜27边缘设置金属外壳,从而可以避免需额外设置接地线,使得接地线和氧化铟锡薄膜边缘存在距离,减小了触摸显示面板的边框宽度。

优选地,所述金属外壳24通过连接线与所述触摸芯片的接地端连接,其中所述连接线位于所述触摸显示面板的外部。通过外部的连接线,使得金属外壳和触摸芯片的接地端之间形成稳定的连接,避免在面板内部设置连接线时,与面板内部的线路之间出现短接以及干扰问题,其次与其他连接方式相比,也可降低制程的难度。
优选地,所述触摸显示面板还包括保护玻璃23,所述金属外壳位于所述保护玻璃23内部。即金属外壳嵌在保护玻璃中,能够缩减金属外壳与触摸芯片的连接距离,且不容易损坏金属外壳,能够更好地避免噪声的干扰。
优选地,所述触摸显示面板还包括保护玻璃23,所述金属外壳位于所述保护玻璃23外部,如图3所示。即金属外壳包裹着保护玻璃,一方面可以对保护玻璃进行保护,另一方面设置在外部,使得制程比较容易,同时也可方便更换金属外壳。特别在制作多种尺寸的触摸显示面板时,更加方便。
优选地,所述检测单元,还用于当所述判断结果为所述触摸显示面板上有所述触控操作时,对所述检测信号处理得到所述触控操作的位置。譬如当用户触摸显示屏幕的某个位置时,使得触摸区域的电容值发生变化,输出检测信号,有触控的区域产生的检测信号与没有触控的区域产生的检测信号不一样。
本发明的触摸显示面板,用金属外壳替换现有的接地线,从而进一步减小了面板的边框宽度。
本发明还提供一种触摸显示装置,其包括背光源,以及触摸显示面板;所述背光源优选为指向性背光源,能够更好地利用光源,降低光源的浪费。结合图3,所述触摸显示面板包括:

金属外壳24,位于所述触摸芯片的外部,所述金属外壳24与参考线之间的距离小于预设值,其中所述参考线为所述驱动线或者所述感测线中距离所述金属外壳最近的线;
其中所述金属外壳24与所述触摸芯片的接地端连接,以避免噪声对所述驱动线和所述感测线上的信号干扰。
优选地,所述触摸显示面板具有4个侧面,所述金属外壳24包裹所述触摸显示面板的全部侧面。
优选地,所述驱动线21、所述感测线22、所述触摸芯片以及所述金属外壳24一体形成。
优选地,所述金属外壳24通过连接线与所述触摸芯片的接地端连接,其中所述连接线位于所述触摸显示面板的外部。
本发的触摸显示装置可包括上述任何一种触摸显示面板,鉴于触摸显示面板在上文已有详述,在此不在赘述。
本发明的触摸显示装置,用金属外壳替换现有的接地线,可直接在氧化铟锡薄膜27边缘设置金属外壳,从而可以避免由于额外设置接地线,使得接地线和氧化铟锡薄膜边缘存在距离,减小了触摸显示面板的边框宽度。同时本发明将触摸显示面板中除金属外壳以外的部分与金属外壳制作成一个整体的结构,可避免在贴合过程中,使得氧化铟锡薄膜边缘到保护玻璃边缘存在的距离,从而进一步减小了触摸显示面板的边框宽度,实现了窄边框的设计。
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。
