Description
本发明涉及液晶显示技术领域，特别是涉及一种液晶显示装置及设备。
随着液晶技术的不断发展，对液晶显示设备内各部件的要求越来越高。
现有技术的软板上芯片（Chip On Film，COF）型封装构造基本上都采用带载自动键合（Tape
Automated
Bonding，TAB）技术进行驱动芯片的热压合封装，并以成卷的方式进行卷带和送带的。在使用时，每一软板上芯片构造可依序自卷带基板被切割下来，并电性连接于一液晶面板的玻璃基板上的透明电路与一驱动电路板之间。玻璃基板与驱动电路板之间可包含一个或数个软板上芯片构造，液晶面板的尺寸愈大，使用的软板上芯片构造的颗数就愈多。
譬如请参阅图1，图1为现有技术中液晶显示装置的结构示意图，其包括有驱动电路板11，液晶面板13，以及数个卷带芯片12。
其中，卷带芯片12设置于所述液晶面板13和所述驱动电路板11之间，用于实现所述驱动电路板11和所述液晶面板13间的电信号的导通。而随着对高解析度的技术需求，作为液晶面板驱动的卷带芯片12的数量越来越多，以至于卷带芯片12密布于液晶面板的源极。譬如在图1中，沿所述驱动电路板11的延伸方向，即横向M'，密密麻麻的排列有数个卷带芯片12，由于卷带芯片12的数量巨大，造成机构设计受到限制，譬如安装螺钉的分布设置。在所述卷带芯片12
的引脚（lead）宽度受到制程限制的情况下，所述卷带芯片12的焊接（bonding）问题将是发展超高清液晶面板的瓶颈。
因此，如何在所述卷带芯片12的数量一定的情况下，减少所述卷带芯片12在横向M'的排列，节省空间以便于对所述卷带芯片12的焊接等工序，是液晶面板技术领域研究的方向之一。
本发明的一个目的在于提供一种液晶显示装置，以解决现有技术中由于卷带芯片的数量巨大，在沿驱动电路板横向排列过密，造成机构设计受到限制的技术问题。
本发明的一个目的在于提供一种液晶显示设备，以解决现有技术中由于卷带芯片的数量巨大，在沿驱动电路板横向排列过密，造成机构设计受到限制的技术问题。
本发明构造了一种液晶显示装置，包括：
驱动电路板，其沿一横向延伸；
液晶面板；
数个连接单元，其设置于所述驱动电路板和所述液晶面板之间，用于连接所述驱动电路板以及所述液晶面板；其中所述连接单元包括：
至少两个卷带芯片，其覆盖设置，且均连接所述驱动电路板以及所述液晶面板；其中沿与所述横向垂直的纵向，每一卷带芯片具有不同的宽度。
本发明的一个目的在于提供一种液晶显示设备，以解决现有技术中由于卷带芯片的数量巨大，在沿驱动电路板横向排列过密，造成机构设计受到限制的技术问题。
为解决上述问题，本发明构造了一种液晶显示设备，包括一液晶显示装置，所述液晶显示装置包括：
驱动电路板，其沿一横向延伸；
液晶面板；
数个连接单元，其设置于所述驱动电路板和所述液晶面板之间，用于连接所述驱动电路板以及所述液晶面板；其中所述连接单元包括：
至少两个卷带芯片，其覆盖设置，且均连接所述驱动电路板以及所述液晶面板；其中沿与所述横向垂直的纵向，每一卷带芯片具有不同的宽度。
本发明相对于现有技术，驱动电路板和液晶面板之间设置有数个连接单元，每一连接单元均包括有至少两个卷带芯片，所述至少两个卷带芯片覆盖设置，且均连接所述驱动电路板以及所述液晶面板，通过上述对连接单元的设置，可使得至少两个卷带芯片集中形成于其中一连接单元，进而可减少所述卷带芯片在沿驱动电路板的延伸方向的排列空间，从而节省空间，便于进行其它设计，譬如对卷带芯片的焊接设计，或者是增加其它设备等。

图2为本发明较佳实施例提供的液晶显示装置的结构示意图；
图3为图2的部分结构示意图；
图4为图3的放大结构示意图；
图5为图3的侧视图。
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。
请参阅图2，图2为本发明实施例提供的液晶显示装置的结构示意图，其包括有驱动电路板21、液晶面板22以及数个连接单元23。
其中所述驱动电路板21沿横向M延伸，所述连接单元23沿所述横向M排列设置，每一所述连接单元23分别连接所述驱动电路板21和液晶面板22。
本发明实施例中，每一所述连接单元23内包括有至少两个卷带芯片，譬如两个、三个或者更多个，所述至少两个卷带芯片覆盖设置（譬如请参阅图5），且均连接所述驱动电路板21以及所述液晶面板22。沿所述横向M，每一所述卷带芯片均具有一长度，每一所述卷带芯片的长度可相等，也可不相等，优选为相等；而沿与所述横向M垂直的纵向N，每一卷带芯片具有不同的宽度，以使得所述卷带芯片可覆盖设置。在每一连接单元23内的卷带芯片之间可具有一间隔，避免每一连接单元23内的卷带芯片相互碰触到。
为了详细的说明本发明，本实施例仅以所述连接单元23包括两个卷带芯片为例进行说明。
请一并参阅图2和图3，图2和图3仅仅是以所述连接单元23包括两个卷带芯片为例进行说明，在具体实施过程中，所述连接单元23还可包括三个、四个甚至更多个卷带芯片，均在本发明保护范围内。
其中所述连接单元23包括第一卷带芯片231和第二卷带芯片232，其中所述第二卷带芯片232覆盖所述第一卷带芯片231。沿所述横向M，所述第一卷带芯片231具有第一长度D1，所述第二卷带芯片232具有第二长度D2，优选的，所述第一长度D1等于所述第二长度D2。
而沿纵向N，所述第一卷带芯片231具有第一宽度L1，所述第二卷带芯片232具有第二宽度L2，其中所述第二宽度L2大于所述第一宽度L1，以使得所述第二卷带芯片232覆盖所述第一卷带芯片231。
而且，为了使得所述第二卷带芯片232进一步的与所述第一卷带芯片231覆盖设置，本发明实施例将所述第二卷带芯片232的末端设置成弯折状，譬如请参阅图5，图5为图3的侧视图，从而使得所述第二卷带芯片232覆盖所述第一卷带芯片231。
请参阅图4，为将所述第一卷带芯片231和所述第二卷带芯片232分别固定连接所述驱动电路板21以及所述液晶面板22，本发明实施例在所述驱动电路板21设置有两排的引脚，分别为第一外引脚a和第一内引脚b，对应的，所述液晶面板22设置有两排的引脚，分别为第二外引脚a'和第二内引脚b'。
本发明实施例中，所述液晶面板22包括第一基板221和第二基板222，所述第一基板221譬如为彩色滤光片（Color
Filter，CF）基板，所述第二基板222譬如为薄膜场效应晶体管（Thin Film Transistor，TFT
）基板，而图4所示的所述第二外引脚a'和第二内引脚b'是形成于所述第二基板222上。
由此，在对所述第一卷带芯片231和所述第二卷带芯片232固定时，将位于内侧的所述第一卷带芯片231分别连接所述第一内引脚b和所述第二内引脚b'，将位于外侧的所述第二卷带芯片232分别连接所述第一外引脚a和所述第二外引脚a'，由于所述第二卷带芯片232的末端为弯折结构，且所述第二卷带芯片232的第二宽度L2大于所述第一卷带芯片231的第一宽度L1，因此可以实现将所述第二卷带芯片232横跨于所述第一卷带芯片231的上方，并使得所述第二卷带芯片232与所述第一卷带芯片231相互间隔，不会接触，避免信号串扰。
本发明实施例还提供一种液晶显示设备，所述液晶显示设备包括本发明实施例提供的液晶显示装置，鉴于所述液晶显示装置在上文已有详细的描述，此处不再赘述。
本发明实施例中，驱动电路板和液晶面板之间设置有数个连接单元，每一连接单元均包括有至少两个卷带芯片，所述至少两个卷带芯片覆盖设置，且均连接所述驱动电路板以及所述液晶面板，通过上述对连接单元的设置，可使得至少两个卷带芯片集中形成于其中一连接单元，进而可减少所述卷带芯片在沿驱动电路板的延伸方向的排列空间，从而节省空间，便于进行其它设计，譬如对卷带芯片的焊接设计，或者是增加其它设备等。
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。
