具体实施方式
为了便于理解本申请，下面将参照相关附图对本申请进行更全面的描述。附图中给出了本申请的较佳实施例。但是，本申请可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本申请的公开内容的理解更加透彻全面。
参考图1，一种驱动电路架构，包括显示面板10，还包括设置在显示面板10同一侧的第一驱动电路板模组20和第二驱动电路板模组30。第一驱动电路板模组20和第二驱动电路板模组30分别与显示面板10电连接。其中，参考图2和图3，第一驱动电路板模组20包括控制驱动电路板210、多个设有源极驱动芯片231的第一源极驱动软板230。第二驱动电路板模组30，包括源极驱动电路板310、多个设有源极驱动芯片331的第二源极驱动软板330。相邻设置的第一源极驱动软板230、第二源极驱动软板330通过显示面板10上的走线对应连接，第一源极驱动软板230将接收的控制驱动电路板210发出的控制信号通过走线、第二源极驱动软板330传输至源极驱动电路板310。
对于大尺寸显示面板10，需要两个驱动电路板，也即一实施例中的控制驱动电路板210和源极驱动电路板310。可确保驱动电路板不会因为过长而产生弯曲形变造成损毁。相邻设置的第一源极驱动软板230、第二源极驱动软板330通过显示面板10上的走线对应连接，可将控制驱动电路板210发出的控制信号依次经第一源极驱动软板230、显示面板10、第二源极驱动软板330传输至源极驱动电路板310。相比传统的信号传输方式，可节省柔性扁平线缆和两个连接器的物料成本和人工组装成本，同时还简化了整个机构的架构。
其中，控制驱动电路板210用于输出控制信号并通过第一源极驱动软板230传输至显示面板10。在一实施例中，控制驱动电路板210将传统的控制板和源极驱动板集成在一起，其中，控制驱动电路板210上集成了控制板(Control Board，CB)上的DC/DC电源模块(产生给显示面板10的电压和时序控制模块芯片的电压)和P-gamma模块(可编程伽玛校正缓冲电路晶片)以及源极驱动板(Source Board)上用于输出驱动源极驱动芯片的源极驱动信 号的控制模块。
控制驱动电路板210、第一源极驱动软板230、显示面板10依次连接，控制驱动电路板210将输出控制信号经第一源极驱动软板230传输给显示面板10，同时将源极驱动信号经第一源极驱动软板230传输至第一源极驱动软板230上的源极驱动芯片231，由源极驱动芯片231驱动显示面板10。
源极驱动电路板310用于输出源极驱动信号，并将源极驱动信号传输至第二源极驱动软板330上的源极驱动芯片331，由源极驱动芯片331驱动显示面板10。
参考图2，第一源极驱动软板230的两端分别设有第一旁路走线区232和第二旁路走线区236。其中，第一旁路走线区232和第二旁路走线区236分别位于第一源极驱动软板230的两端。
参考图3，第二源极驱动软板330的两端分别设有第三旁路走线区332和第四旁路走线区336。第三旁路走线区332和第四旁路走线区336分别位于第二源极驱动软板330的两端。相邻设置的第一源极驱动软板230、第二源极驱动软板330中，其中，第二旁路走线区236、第三旁路走线区332相邻设置。
具体地，相邻设置的第一源极驱动软板230、第二源极驱动软板330通过显示面板10的走线对应连接。其中，第一源极驱动软板230的第二旁路走线区236通过显示面板10的走线与第二源极驱动软板330的第三旁路走线区332对应连接。
在一实施例中，可以根据实际的需求，在相邻设置的第一源极驱动软板230、第二源极驱动软板330中，第一源极驱动软板230的第一旁路走线区232还可以通过显示面板10的走线与第二源极驱动软板330的第四旁路走线区336对应连接，这样增加了信号传输的通道，为多信号传输提供了基础。
参考图4，显示面板10包括第一金属层110和第二金属层120。在第一金属层110上顺次设有第一贴合区112、第二贴合区114、第三贴合区116和第四贴合区118。
参考图5，其中，第一贴合区112与第一旁路走线区232对应贴合连接，第二贴合区114与第二旁路走线区236对应贴合连接；第三贴合区116与第三旁路走线区332对应贴合连接，第四贴合区118与第四旁路走线区336对应贴合连接。
第一旁路走线区232、第二旁路走线区236、第三旁路走线区332和第四旁路走线区336均设有金手指引脚。第一贴合区112、第二贴合区114、第三贴合区116和第四贴合区118设有多个金手指引脚。
具体地，第一旁路走线区232、第二旁路走线区236的金手指引脚分布第一源极驱动软板230的两侧，其中，第一源极驱动软板230第一侧与控制驱动电路板210相邻，第一源极驱动软板230第二侧与显示面板10相邻。分布在第一源极驱动软板230第一侧的金手指引脚与控制驱动电路板210贴合连接。其中，第一旁路走线区232的金手指引脚与显示面板10的第一贴合区112的金手指引脚对应贴合连接，第二旁路走线区236的金手指引脚与显示面板10的第二贴合区114的金手指引脚对应贴合连接。分布在第一源极驱动软板230第二侧的金手指引脚与显示面板10的第一金属层110对应贴合连接。
相应地，第三旁路走线区332、第四旁路走线区336的金手指引脚分布第二源极驱动软板330的两侧，其中，第二源极驱动软板330第一侧与源极驱动电路板310相邻，第二源极驱动软板330第二侧与显示面板10相邻。分布在第二源极驱动软板330第一侧的金手指引脚与源极驱动电路板310贴合连接，其中，第三旁路走线区332的金手指引脚与显示面板10的第三贴合区116的金手指引脚对应贴合连接，第四旁路走线区336的金手指引脚与显示面板10的第四贴合区118的金手指引脚对应贴合连接。分布在第二源极驱动软板330第二侧的金手指引脚与显示面板10的第一金属层110对应贴合连接。
第二金属层120上设有金属走线。金属走线通过通孔延伸至第一金属层110的金手指引脚上。第一贴合区112的金手指引脚通过金属走线与第四贴合 区118的金手指引脚对应连接，第二贴合区114的金手指引脚通过金属走线与第三贴合区116的金手指引脚对应连接。
上述显示面板驱动电路架构相比传统的信号传输方式，可节省柔性扁平线缆和两个连接器的物料成本和人工组装成本，同时还简化了整个机构的架构。
在一实施例中，参考图2，第一源极驱动软板230上还设有第一输入走线区235、第一输出走线区237。第一输入走线区235、第一输出走线区237去对应设置在第一旁路走线区232、第二旁路走线区236之间。控制驱动电路板210通过第一输入走线区235将控制信号传输给源极驱动芯片231；源极驱动芯片231输出的电压信号经第一输出走线区237传输至显示面板10。
在一实施例中，参考图3，第二源极驱动软板330上还设有第二输入走线区335、第二输出走线区337。第二输入走线区335、第二输出走线区337对应设置在第三旁路走线区332、第四旁路走线区336之间。源极驱动电路板310将源极驱动信号通过第二输入走线区335传输给源极驱动芯片331；源极驱动芯片331输出的电压信号经第二输出走线区337传输至显示面板10。其中，第一输入走线区235、第一输出走线区237、第二输入走线区335、第二输出走线区337也设有多个金手指，金手指的数量和间距可以根据需求来设定，在一实施例中，第一输入走线区235、第一输出走线区237的金手指等间距对应设置；第二输入走线区335、第二输出走线区337的金手指等间距对应设置。
相应的，显示面板10的第一金属层110上也设有第一输入贴片区113和第二输入贴片区115。其中，第一输入走线区235与第一输入贴片区113的金手指一一对应贴合连接。第二输入走线区335与第二输入贴片区115的金手指一一对应贴合连接。第一输入贴片区113、第二输入贴片区115上的金手指通过位于第二金属层120上的金属走线一一对应连接。
在一实施例中，第一源极驱动软板230的数量与第二源极驱动软板330的数量相等。其中，第一源极驱动软板230、第二源极驱动软板330的数量 均为三个。在其他实施例中，第一源极驱动软板230、第二源极驱动软板330的数量也可根据实际需求来设定，也可以不相等。
在一实施例中，设于第一源极驱动软板230的源极驱动芯片231与设于第二源极驱动软板330上的源极驱动芯片331相同，且各源极驱动芯片(221、321)输出的信号强度相同。由于其源极驱动芯片输出的信号强度相同，可消除显示面板10在各第一源极驱动软板230、第二源极驱动软板330之间明显的分界线现象(H-block issue或Block Dim现象)，从而提高显示品质。
在一实施例中，驱动电路架构还包括第三驱动电路板模组(图中未示)。第三驱动电路板模组与第一驱动电路板模组不在显示面板10的同一侧；第三驱动电路板模组包括栅极驱动电路板、多个设有栅极驱动芯片的栅极驱动软板。栅极驱动电路板通过栅极驱动软板与显示面板10连接。
一种显示装置(图中未示)，包括背光模块，还包括驱动电路架构，驱动电路架构位于背光模块出光面的一侧。
本实施例的显示装置包括驱动电路架构与背光模块。驱动电路架构配置于背光模块的一侧。具体而言，驱动电路架构是配置于背光模块的一出光面上。本实施例的背光模块是以采用侧边入光式设计为例，但在显示装置的尺寸为37时或更大时，背光模块40常采用直下式设计。此外，显示装置更可具有前框(图中未示)，用以使驱动电路架构可更稳固的配置在背光模块上。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
