图2为本公开的显示装置在实际应用中的结构示意图。
具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
针对相关技术中的去静电方案因静电导出路径的线幅较窄使得电阻较大而容易发生击穿绝缘层的问题,本公开提供一种解决方案。
一方面,本公开的一些实施例提供一种显示装置,如图1所示,包括显示面板(包括下基板1和上基板2)、用于封框显示面板的外壳3,显示装置还包括:
设置在外壳3内部,用于支撑外壳3的金属骨架4,该金属骨架4连接地线8;
设置在显示面板的封框胶5外侧的导体单元6,所述导体单元6与显示面板的上基板2和/或下基板1连接,并与金属骨架4连接。
本公开的一些实施例中,如图1所示,金属骨架4位于显示面板和外壳3之间
本公开的一些实施例的显示装置将外壳内的金属骨架复用为静电导出的路径,可不需要受到布线空间的限制,从而使得静电路径具有较小的电阻,有效避免了静电因传输路径不够而击穿绝缘层的现象发生。
下面结合实现方式对本公开的一些实施例的显示装置进行详细介绍。
本公开的一些实施例的导体单元6可以与显示面板的上基板2连接,也可以与显示面板的下基板1连接,与上基板2连接可消除上基板2的静电,同理与下基板1连接则可以消除下基板1的静电。
本公开的一些实施例中,导体单元6应同时连接上基板2和下基板1,从而达到更好的静电导出效果。
具体地,针对下基板1的去静电方式,本公开的一些实施例在该下基板1上设置有公共电极线11和覆盖公共电极线11的绝缘层12,绝缘层12包括有位于封框胶5外侧的过孔(图中椭圆形虚线处);
其中,导体单元6包括:通过上述过孔与公共电极线11连接的导电连接线61。
从上述结构可以看出,本公开的一些实施例的导体单元6可以消除公共电极线11上的静电。
当然,在上述基础之上,本公开的一些实施例的导体单元6还包括:
覆盖导电连接线61的导电胶62,该导电胶62与金属骨架4连接。
显然,导电胶62具有密封作用,能够密封绝缘层12上的过孔,从而防止公共电极线11以及导电连接线61被氧化。
在实际应用中,导电胶62可以很易于涂覆设置,特别适用于将导电连接线61与金属骨架4电连接。当然,本公开的一些实施例也并不限于只能是使用导电胶62连接金属骨架4与导电连接线61,任何电连接方式均应属于本公开的保护范围之内。
对于上基板2去静电方案,则本公开的一些实施例的上基板2设置有黑矩阵21,其中,该黑矩阵21至少一部分位于封框胶5的外侧。导电胶62与黑矩阵21位于封框胶5外侧的一部分接触,从而将黑矩阵21电连接金属骨架4,以达到去静电功能。
本公开的一些实施例中,如图1、2所示,下基板1设置有公共电极线11 和覆盖公共电极线11的绝缘层12,绝缘层12包括位于封框胶5远离显示区域9一侧的过孔63。导体单元包括:通过过孔121与公共电极线11连接的导电连接线61。
本公开的一些实施例中,如图1、2所示,上基板2设置有黑矩阵21,黑矩阵21至少一部分位于封框胶5远离显示区域9一侧,导电胶62与黑矩阵21位于封框胶5远离显示区域9一侧的一部分接触。
本公开的一些实施例中,如图1所示,绝缘层12中的过孔121在下基板1上的正投影与公共电极线11在下基板1上的正投影至少部分重叠。
本公开的一些实施例中,如图1所示,导电连接线61伸入绝缘层12中的过孔121,与公共电极线11直接接触。
本公开的一些实施例中,如图1所示,黑矩阵21在下基板1上的正投影与导电连接线61在下基板1上的正投影至少部分重叠。
经不断验证发现,当用户与屏幕接触的过程中,身体上的生物静电会从上基板2的黑矩阵21导入至显示面板的内部。由此可见,本公开的一些实施例使用导体单元6将黑矩阵21电连接至金属骨架4上可有效避免静电影响显示面板显示画面,从而为用户提供了更好体验效果。
下面结合实际应用对本公开的一些实施例的显示装置进行详细介绍。
如图2所示,本公开的一些实施例的显示面板中,印刷线路板PCB设置在显示面板的下侧,则导电单元6位于下基板远离印刷线路板PCB的一侧,从而避免干扰印刷线路板PCB所加载的相关技术中的信号。
本公开的一些实施例的导电单元6为两个,分别设置在显示面板左右两侧的上方,每个导电单元6在其设置区域处的绝缘层上对应过孔设置,从而使其导电连接线通过对应的过孔与公共电极线连接。
可以知道的是,本公开的一些实施例的去静电方案可以与相关技术中的去静电方案相互兼容,通过上文介绍可以知道,一般静电击穿更容易发生在远离印刷线路板PCB的一侧,因此当本公开的一些实施例的导电单元6与印刷线路板PCB远离设置可以弥补相关技术中的去静电方案的缺陷。
综上所述,本公开的一些实施例的显示装置在上述实际应用中具有以下优点:
1)增加了新的导体单元和放电路径(金属骨架作为静电导出路径,使得ESD发生风险降低;
2)本公开的一些实施例的金属骨架是围绕显示区域的框体,地线与金属骨架连接,从而使得地线设置限制得到了放宽;
3)降低静电对PCB及其附近电子器件的冲击和损害。
以上是本公开的一些实施例的显示装置的示例性介绍,需要说明的是,本公开的一些实施例的导电单元并不一定只限于通过黑矩阵与上基板连接,作为其他可行方案,还可以是与上基板的彩色滤光片和/或绝缘层连接;同理,导电单元也不一定只限于与下基板的公共电极线连接,作为其他可行方案,还可以与下基板的扫描线和/或数据线连接。因此,但凡是使用导电单元将上基板和/或下基板上的功能图形与接地的金属骨架进行电连接的技术方案,都应属于本公开的保护范围。
此外,本公开的一些实施例中,地线与上述公共电极线、数据线、扫描线之间的路径上还以进一步设置有低阻值的双向二极管。这是因为相关技术中的部分显示器的公共电极线(数据线和扫描线同理)的电位在7V至8V左右为合理取值,而非0V。因此只需要将其公共电极的电位降低至7V-8V左右即可。当公共电极上线的电位大于一定门限后(如上述的7V-8V,可根据具体情况进行合理设置),本公开的一些实施例的双向二极管才会导通,从而由地线进行静电释放。在释放过程中,当公共电极线的电位降低至上述门限左右时,双向二极管断开,从而结束静电释放。
当然,本公开的一些实施例的双向二极管可以具体设置在金属骨架与地线之间,由于金属骨架是外边框区域,因此双向二极管不会占用中间的显示区,对于布置要求更加灵活。
另一方面,本公开的一些实施例还提供一种显示装置的制作方法,包括制作显示面板的步骤和使用外壳封框所述显示面板的步骤;
参考图1所示,其中使用外壳封框所述显示面板的步骤包括:
在外壳3内部设置金属骨架4,以用于支撑外壳3,并将该金属骨架4连接地线8;
本公开的一些实施例的制作方法还包括:
在显示面板的封框胶5外侧设置导体单元6的步骤,该导体单元6与显示面板的上基板2和/或下基板1连接,并与金属骨架4连接。
显然,本公开的一些实施例的制作方法用于制作本公开提供的上述显示装置,因此该显示装置所能实现的技术效果,本公开的一些实施例的制作方法同样也能够实现。
具体地,本公开的一些实施例的制作方法可以消除下基板1的静电,因此在显示装置制作的过程中,制作显示面板的步骤包括:
在下基板1上设置公共电极线11和覆盖公共电极线11的绝缘层12,该绝缘层包括有位于封框胶外侧的过孔(图1椭圆形虚线处);
对应地,在显示面板的封框胶5外侧的设置导体单元6的步骤,包括:
在下基板1上形成导电连接线61,该导电连接线61通过该过孔与公共电极线11连接。
对应地,在显示面板的封框胶5外侧设置导体单元6的步骤还包括:
形成覆盖导电连接线61的导电胶62,导电胶62与金属骨架4连接,从而使得上述公共电极线11通过导电连接线61、导电胶62与金属骨架4连接,进而通过金属骨架4连接地线8。
作为示例性介绍,本公开的一些实施例的导电胶62可以是掺杂有导电颗粒(如银质颗粒)的树脂材料制成,具有一定密封性,通过覆盖导电连接线61可以避免导电连接线61被空气氧化,同时还可以密封绝缘层12过孔,防止下方的公共电极线11也被氧化。
本公开的一些实施例可以通过下基板相关技术中的像素电极的构图工艺来制作导电连接线61,即导电连接线61与相关技术中的像素电极由同一透明导电材料层经图案化处理后形成,从而在相关技术中的制作工艺基础上不需要额外增加制作工序就可实现本公开的一些实施例的技术方案。
此外,本公开的一些实施例的制作方法还可以去除上基板2的静电,即如图1所示,上述制作显示面板的步骤还包括:
在上基板2设置黑矩阵21,黑矩阵21至少一部分位于封框胶5的外侧;
其中,本公开的一些实施例制作出的导电胶62与黑矩阵21位于封框胶6外侧的一部分接触,从而使得黑矩阵21能够通过导电胶62和金属骨架4 与地线8电连接。
通过上文描述可以知道,用户在进行触控操作时,其身体的生物静电容易从上基板2的黑矩阵中进入至显示面板内部,显然,基于本公开的一些实施例的方案,可以有效避免用户的生物静电干扰显示面板的正常显示。
此外,本公开的一些实施例在将该金属骨架4连接地线8的步骤中,可以具体将金属骨架4通过双向二极管7与地线8连接,当公共电极线的上电位大于一门限时,则说明存在静电,此时双向二极管7才会导通,使得地线8释放公共电极上的电位,降低击穿绝缘层的风险;当公共电极线上的电位被降低至合理数值时,则双向二极管7断开,从而停止释放过程。
以上所述是本公开的一些实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本公开所述原理的前提下,还可以作出若干改进和润饰,这些改进和润饰也应视为本公开的保护范围。
