相关申请
本申请要求2018年12月12日申请的，申请号为201811523057.4，名称为“显示面板和显示装置”的中国专利申请的优先权，在此将其全文引入作为参考。
技术领域
本申请涉及显示产品技术领域，特别涉及一种显示面板和显示装置。
背景技术
这里的陈述仅提供与本申请有关的背景信息，而不必然地构成。高清数字显示接口（V by one接口）是显示产品技术领域广泛使用的接口，其具有功耗低、数据传输量大（有效数据量达到3.2Gbps）,并从根本上解决了传输线时滞问题，同时其不需要时钟传输线，因此具有很强的抑制EMI的能力。由于V by one 信号把时钟信号嵌入数据中，不需要专门的时钟信号对，所以不存在信号偏移问题，可以很好的设置为高速长距离信号传输。
可以理解，V by one接口采用交流耦合，交流耦合在信号发送端和接收端之间串接一个电容，这样信号的直流分量就被隔离，截止频率取决于耦合电容的大小，信号的低频交流分量也会受阻大为衰减，但高频信号的交流分量仍能很好的通过，所以高速串行信号一般采用交流耦合方式。
在显示面板的一示例性技术中，逻辑控制板作为V by one的信号接收端，设计时在逻辑控制板前端的每一路V by one上都会串接有一耦合电容，如此，造成显示面板信号驱动组件的成本较高。
发明内容
本申请的主要目的是提出一种显示面板，旨在降低显示面板信号驱动组件的成本。
为实现上述目的，本申请提出的显示面板，包括：
驱动电路板，用以连接信号发送端和信号接收端；所述驱动电路板包括相邻且绝缘设置的第一板层和第二板层，所述第一板层上设有第一导电部，所述第二板层上设有第二导电部；其中，
所述第一导电部与第二导电部至少部分相对设置，以在两者之间形成一耦合电容。
本申请还提出一种显示面板，包括：
驱动电路板，用以连接信号发送端和信号接收端；所述驱动电路板包括相邻且绝缘设置的第一板层和第二板层；以及
两焊盘，分设于所述第一板层和第二板层上；两所述焊盘正对设置，以间隔形成一耦合电容。
本申请还提出一种显示装置，包括显示面板，该显示面板包括：
驱动电路板，用以连接信号发送端和信号接收端；所述驱动电路板包括相邻且绝缘设置的第一板层和第二板层，所述第一板层上设有第一导电部，所述第二板层上设有第二导电部；其中，
所述第一导电部与第二导电部至少部分相对设置，以在两者之间形成一耦合电容。
本申请技术方案通过于驱动电路板的两相邻板层上分别设置一导电部，并利用两导电部之间正对的部分形成一耦合电容，从而避免额外引入一贴片电容，如此，有效简化了显示面板驱动组件的结构，降低了显示面板驱动组件的生产成本。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。

本申请提出一种显示面板，该显示面板包括但不限于液晶显示面板、有机发光二极管显示面板、场发射显示面板、等离子显示面板、曲面型面板，液晶面板包括薄膜晶体管液晶显示面板、TN面板、VA类面板、IPS面板等。
在液晶显示面板中，为了降低信号数据传输的功耗、提高信号数据传输量，往往采用V by one接口，而示例性技术中的与液晶显示面板的逻辑控制板相连的每一路V by one 上均串接有一耦合电容，由于该耦合电容是额外设置的贴片电容，造成了液晶显示面板信号驱动组件的成本较高。本申请的技术方案针对该技术问题进行了改善：
在本申请实施例中，如图1所示，该液晶显示面板包括：
驱动电路板1，用以连接信号发送端（图未示）和信号接收端（图未示）；驱动电路板1包括相邻且绝缘设置的第一板层11和第二板层12，第一板层11上设有第一导电部2，第二板层12上设有第二导电部3；其中，
第一导电部2与第二导电部3至少部分相对设置，以在两者之间形成一耦合电容。
可以理解，本申请的技术方案利用了驱动电路板1的多层架构，并于相邻的两板层（第一板层11和第二板层12）上分别设置导电部，又由于两板层之间呈绝缘设置，因此，两导电部（第一导电部2和第二导电部3）的正对部分即可形成电容，以替代原本额外设置的贴片电容，如此，将耦合电容集成于驱动电路板1上，无疑能够有效降低液晶显示面板的整体成本。
本实施例中，驱动电路板1还包括第三板层13和第四板层14，换言之，驱动电路板1整体包括四层，四层是常规的电路板结构设计，四层之间分隔形成有三段间隔距离，该驱动电路板1的整体厚度为1mm，为了降低工艺难度，可选将三段间隔距离设置为相等，则第一板层11与第二板层12之间的间距为0.33mm，即第一导电部2与第二导电部3之间的间距为0.33mm（第一导电部2和第二导电部3的厚度忽略不计）。应当说明的是，本设计不限于此，于其他实施例中，驱动电路板1的工艺在厚度上可能存在±0.1mm的误差值，因此，第一导电部2和第二导电部3之间的间距也可在0.3mm~0.37mm之间取值；而且，于其他实施例中，驱动电路板1还可具体呈其他板层数设置。
在示例性技术中，V by one 上串接的耦合电容的电容值为100nF，以获得较佳的隔离信号直流风量的效果，本实施例中，同样将第一导电部2和第二导电部3之间形成的耦合电容的电容值设置为100nF，根据电容公式：
C=Q/U=εS/4πd
式中：C——电容量(F)
Q——一个电极板上储存的电荷（C）
U——个电极板上的电位差（V）
ε——绝缘介质的介电常数
S——金属极板的面积（m2）
d——极板间的距离（cm）
由于驱动电路板1的层与层之间的距离是固定的，即以上公式中的d是常数，本实施例中，d=0.33mm，而为了获得100nF的电容，可以根据以上公式求得电容极板的面积S，即根据该面积S设置第一导电部2与第二导电部3相互正对的面积。
本申请技术方案通过于驱动电路板1的两相邻板层上分别设置一导电部，并利用两导电部之间正对的部分形成一耦合电容，从而避免额外引入一贴片电容，如此，有效简化了液晶显示面板驱动组件的结构，降低了显示面板驱动组件的生产成本。
为了避免第一导电部2和第二导电部3的结构浪费，本实施例中，第一导电部2与第二导电部3平行且正对设置；可以理解，如此设置，第一导电部2和第二导电部3均完全充当耦合电容的电极板，在第一导电部2和第二导电部3使用面积一定的情况下，增大耦合电容的电容值。需要说明的是，本设计不限于此，于其他实施例中，第一导电部2和第二导电部3也可仅部分正对设置，仅第一导电部2和第二导电部3的正对部分之间形成该耦合电容。
另外，为了简化液晶显示面板的驱动组件的整体结构，本实施例中，第一导电部2与第二导电部3的结构一致，即两者采用完全相同的结构设计，如此，一方面，方便两导电部的加工，有利于提高液晶显示面板整体的生产加工效率，另一方面，在任一者发生破损时，均可使用另一者进行替换，降低了显示面板整体的维护成本。应当说明的是，本设计不限于此，于其他实施例中，第一导电部2和第二导电部3的结构也可各自不同设置。
不失一般性，第一导电部2和第二导电部3均为焊盘；具体地，如上，根据以上电容公式求得所需电容极板的面积S，再通过电脑绘图软件绘制面积为S的焊盘安装在第一板层11和第二板层12上。可以理解，焊盘是广泛使用的导电结构，其便于与电路板焊接、结构稳定、成本较低。应当说明的是，本设计不限于此，于其他实施例中，第一导电部2和第二导电部3也可具体为其他结构。
进一步地，两焊盘与各自所在的板层之间均进行封装处理，如此，以有效避免焊盘出现漏电的情况，以致耦合电容的电容值不够准确，例如但不限于，本实施例中，可以选用封装胶进行焊盘的封装。
为了更好地避免焊盘显露于外，受到外界的磕碰或其他干扰，将焊盘设于驱动电路板1靠内的板层上，本实施例中，第三板层13位于第一板层11背离第二板层12的一侧，第四板层14位于第二板层12背离第一板层11的一侧；如此，两焊盘之间形成的耦合电容位于驱动电路板1的内部，能更好地保证焊盘结构稳定，其形成的耦合电容值准确。
本申请还提出一种显示装置，该显示装置包括显示面板，该显示面板的具体结构参照上述实施例，由于本显示装置采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有优点，在此不再一一赘述。
以上所述仅为本申请的可选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
