本申请涉及显示装置技术领域，尤其涉及一种显示装置及电子设备。
背景技术
使用液晶技术的显示类产品普遍存在动态对比度低、峰值亮度低的缺点，高动态对比度、高峰值亮度对显示类产品的显示效果的提升显而易见，但次毫米发光二极管(miniLED)技术可解决该问题。miniLED的背光模组包括灯板，将灯板中的灯珠分成多个分区，结合驱动技术，实现图像的同步控制，使得图像该亮的位置更亮，该暗的位置更暗，形成强烈的明暗对比，达到与有机发光二极管(Organic light-emitting Diode，OLED)媲美的显示效果。当前多分区miniLED产品主要问题是成本偏高，降低成本是miniLED产品需要解决的重要问题。其中，灯板是背光模组中成本占比最高的，灯板的基材又是在灯板中的关键物料和成本主要来源，灯板的基材通常为印制电路板(Printed Circuit Board，PCB)。常用的基材包括双层PCB板和单层PCB板，单层PCB板的成本较低，能够降低显示类产品的成本，但是，单层PCB板的空间有限，在分区较多时存在灯珠无法连接的问题。

具体实施方式
为了更好的理解本申请的技术方案，下面结合附图对本申请实施例进行详细描述。
在一种具体实施例中，下面通过具体的实施例并结合附图对本申请做进一步的详细描述。
显示装置包括显示面板和位于所述显示面板的背光侧的灯板，所述灯板包括基板、设置于所述基板的连接器10和多个灯珠。所述基板通常为双层PCB板，在所述基板的双面均能够设置连接线，在所述基板的两面设置电路实现两面的连接，具体在所述基板设置导孔(via)，所述导孔是设置于所述基板的充满或涂上金属的小洞，可以与两面的连接线相连接，使得连接线可以互相交错(可以绕到另一面)，所述基板为双层PCB板时便于布置连接线。所述基板为单层板时，只有一面可以布置连接线，且连接线之间不能交叉，需绕独自的路径或使用跳片将交叉的线路避开，不管是绕线还是跳片的方式，都使得信号质量变差且占用了PCB的面积，不利于分区较多的复杂走线的设计。
如图1所示，所述灯板包括多个灯珠，且图1示出所述灯板的部分所述灯珠。图1所示的所述灯板中，灯珠LED1-LED4形成分区1，灯珠LED5-LED8形成分区2，灯珠LED9-LED12形成分区3，LED13-LED16形成分区4。所述灯板还设置有连接器10，各所述分区均与所述连接器连接，所述连接器与所述显示装置的所述驱动板连接，实现将所述灯区与所述驱动板连接。
图1示出了分区1的灯珠LED1-LED4串联后连接至所述连接器10的两端，分区3的灯珠LED9-LED12串联后连接至所述连接器10的两端，分区2和分区4的各所述灯珠也串联并连接至所述连接器10的两端，图1中未示出分区2和分区4与所述连接器10的连接线。所述灯板的基板为单层PCB板，从图1可知，分区1连接至所述连接器10的连接线与分区3连接至所述连接器10的连接线之间存在交叉，需要设置跳线(图1中的弧线)，当各所述分区的所述灯珠数量继续增多时，所述灯板中设置连接线的空间更小，存在连接线无法布置的风险。
如图2所示，显示装置的灯板包括多个灯珠，且图2示出所述灯板的部分所述灯珠。图2所示的所述灯板中，每个所述灯珠形成单独的分区，即灯珠LED1形成分区1，灯珠LED2形成分区2……，每个所述灯珠均连接至所述连接器10。各所述分区的灯珠数量较少，各分区的亮度较小，影响显示效果，设置连接线的空间较大，方便布置连接线。

本申请实施例用于解决所述目标灯区11中连接线无法布置的问题。具体地，所述目标灯区11包括第一灯珠111、第二灯珠112和第三灯珠113，其中，所述第一灯珠111和所述第二灯珠112为所述目标灯区11中连接线无法布置的灯珠，所述第三灯珠113为所述目标灯区11中除了所述第一灯珠111和所述第二灯珠112之外的其他灯珠，即所述第三灯珠113的连接线能够布置，所述目标灯区11包括一个或多个所述第三灯珠113，当包括多个所述第三灯珠113时，多个所述第三灯珠113串联，并连接至所述VLED和所述第一连接器12。在所述目标灯区11中，所述第一灯珠111和所述第二灯珠112需要连接至所述VLED和所述第一连接器12，并与串联后的所述第三灯珠113连接。
为了将所述目标灯区11中所述第一灯珠111和所述第二灯珠112连接至所述VLED和所述第一连接器12，并与串联后的所述第三灯珠113连接，所述第一连接器12设置有第一引脚121和第二引脚122，所述显示装置还包括与所述第一连接器12连接的传导部件2，所述传导部件2能够用于传导信号，且所述第一引脚121与所述传导部件2和所述第一灯珠111的一端连接，所述第二引脚122与所述传导部件2和所述第二灯珠112的一端连接，以使所述第一灯珠111和所述第二灯珠112通过所述传导部件2连接，所述第一灯珠111和所述第二灯珠112的信号能够通过所述传导部件2传递，所述第一灯珠111的另一端和所述第二灯珠112的另一端中的一者与所述第一连接器12连接，另一者与所述目标灯区11的所述第三灯珠113连接，使得所述第三灯珠113、所述第一灯珠111、所述第一连接器12、所述传导部件2与所述第二灯珠112连接。
图3所示的实施例中，所述目标灯区11包括六个所述灯珠，具体包括四个所述第三灯珠113，分别为LED1-LED4，且四个所述第三灯珠113相互串联，串联后，LED4与所述第二灯珠112(LED6)的一端连接，所述第二灯珠112与第一连接器12的第二引脚122连接，所述第一连接器12的第二引脚122通过第二连接线4与所述传导部件2连接；所述第一灯珠111(LED5)的一端与所述第一连接器12的第一引脚121连接，另一端与所述第一连接器12原有的引脚(除了所述第一引脚121和第二引脚122之外的其他引脚)连接，所述第一引脚121通过第一连接线3与所述传导部件2连接，使得四个所述第三灯珠113(LED1-LED4)、所述第二灯珠112(LED6)、所述第一连接器12的第二引脚122、所述传导部件2、所述第一连接器12的第一引脚121、所述第一灯珠111(LED5)串联，使得所述第一灯珠111与所述第二灯珠112通过所述传导部件2连接。
图4所示的实施例中，所述目标灯区11包括九个所述灯珠，具体包括七个所述第三灯珠113，分别为LED1-LED6和LED9，且七个所述第三灯珠113相互串联，串联后，LED6与所述第二灯珠112(LED7)的一端连接，所述第二灯珠112与第一连接器12的第二引脚122连接，所述第一连接器12的第二引脚122通过第二连接线4与所述传导部件2连接；所述第一灯珠111(LED8)的一端与所述第一连接器12的第一引脚121连接，另一端与所述第一连接器12原有的引脚(除了所述第一引脚121和第二引脚122之外的其他引脚)连接，所述第一引脚121通过第一连接线3与所述传导部件2连接，使得七个所述第三灯珠113(LED1-LED6和LED9)、所述第二灯珠112(LED7)、所述第一连接器12的第二引脚122、所述传导部件2、所述第一连接器12的第一引脚121、所述第一灯珠111(LED8)串联，使得所述第一灯珠111与所述第二灯珠112通过所述传导部件2连接。
本申请实施例的所述灯板1通过设置所述传导部件2，使得连接线无法布置导致无法直接连接的所述第一灯珠111和所述第二灯珠112通过所述传导部件2连接，使得所述灯板1的所述基板能够设置为单层PCB板，降低所述显示装置的成本。
其中，连接同一分区的所述第一引脚121和所述第二引脚122的网络名相同，以传导所述第一灯珠111与所述第二灯珠112之间的信号。
在本申请的实施例中，所述传导部件2为能够用于传导信号的部件，所述传导部件2与所述灯板1可以分体设置，使得所述灯板1的所述目标灯区11中第一灯珠111和所述第二灯珠112通过所述灯板1之外的传导部件2连接，该连接方式不占用所述灯板1的空间，无需在所述灯板1设置连接线实现二者的连接，能够适用于空间有限的灯板1。
其中，所述传导部件2可以为位于所述灯板1外侧的电路板或信号线，所述电路板可以为PCB板，所述信号线可以为柔性电路板(Flexible Printed Circuit，FPC)。本申请实施例对所述传导部件2的具体结构不作限定，只要能够用于传导所述第一灯珠111和所述第二灯珠112之间的信号即可。
在一种具体实施例中，如图3-6所示，所述显示装置包括与所述灯板1连接的驱动板2，所述驱动板2设置有用于驱动所述灯板1的驱动芯片22，所述驱动板2为所述传导部件2，即所述第一连接器12的所述第一引脚121和所述第二引脚122均与所述驱动板2连接，使得连接线无法布置导致无法直接连接的所述第一灯珠111和所述第二灯珠112通过所述显示装置的所述驱动板2连接，该连接方式无需在所述灯板1设置所述第一灯珠111和所述第二灯珠112的连接线，利用所述显示装置的所述驱动板2即可传导所述第一灯珠111和所述第二灯珠112的信号，无需在所述显示装置中设置另外的部件，简化所述显示装置的结构，降低成本。
本申请的实施例中，所述驱动板2用于驱动所述灯板1的各所述灯珠，还用于传导所述目标灯区11的所述第一灯珠111和所述第二灯珠112的信号。
在一种具体实施例中，如图3和图4所示，所述驱动板2设置有第二连接器21，所述驱动板2与所述灯板1通过所述第一连接器12和所述第二连接器21连接，二者具体通过信号线5连接，所述第一连接器12与所述第二连接器21的连接方式可以参考现有技术中所述灯板1与所述驱动板2的连接方式。所述信号线5能够实现所述灯板1与所述驱动板2之间的信号传递，从而通过所述驱动板2驱动所述灯板1工作。如图3和图4所示的实施例中，所述目标灯区11的所述第一灯珠111和所述第二灯珠112位于所述信号线5的两端，即所述第一灯珠111与所述第二灯珠112通过所述信号线5隔开，导致二者的连接线无法布置而无法实现直接连接。在其他实施例中，还可以由其他原因导致所述第一灯珠111与所述第二灯珠112的连接线无法布置，本申请实施例对所述第一灯珠111与所述第二灯珠112的连接线无法布置的原因不作限定，能够解决因多种原因导致的所述第一灯珠111与所述第二灯珠112的连接线无法布置的问题。
具体地，如图3和图4所示，所述第二连接器21设置有第三引脚211和第四引脚212，所述第三引脚211与所述第四引脚212直接或间接连接，所述第三引脚211与所述第四引脚212直接连接时，二者可以通过连接线连接，所述第三引脚211与所述第四引脚212间接连接时，二者可以通过其他能够传导信号的部件连接，例如通过设置于所述驱动板2之外的电路板连接。本申请实施例中，所述驱动板2的空间能够布置所述第三引脚211与所述第四引脚212的连接线，即所述第三引脚211与所述第四引脚212能够直接连接。
本申请的实施例中，如图3和图4所示，所述第一引脚121与所述第三引脚211和所述第一灯珠111连接，所述第二引脚122与所述第四引脚212和所述第二灯珠112连接，以使所述第一灯珠111与所述第二灯珠112通过所述第一引脚121、所述第三引脚211、所述第四引脚212和所述第二引脚122连接。
本申请的实施例中，所述目标灯区11的所述第一灯珠111与所述第二灯珠112的连接线无法布置时，通过在所述灯板1的所述第一连接器12中增加两个引脚(所述第一引脚121和所述第二引脚122)、在所述驱动板2的所述第二连接器21中增加两个引脚(所述第三引脚211和所述第四引脚212)，实现所述第一灯珠111与所述第二灯珠112的连接。上述连接方式只需要在两个连接器原有结构的基础上分别增加两个引脚即可，具有结构简单、便于实现、成本较低的优点。
图3和图4所示的实施例中，所述灯板1包括一个所述目标灯区11(包括连接线无法布置的所述第一灯珠111和所述第二灯珠112的灯区)，所述第一连接器12和所述第二连接器21均增加两个引脚即可。
在本申请的实施例中，所述灯板1包括一个以上的所述目标灯区11时，所述第一连接器12和所述第二连接器21需要设置两个以上的引脚。例如，所述灯板1包括两个所述目标灯区11，即两个灯区的灯珠存在连接线无法布置的情况，两个所述目标灯区11的所述第一灯珠111和所述第二灯珠112均通过所述第一连接器12和所述第二连接器21连接，需要在所述第一连接器12和所述第二连接器21中各增加四个引脚。
当所述灯板1中所述目标灯区11的数量为N时，所述灯板1的N个灯区存在灯珠的连接线无法 布置的情况，需要在所述第一连接器12和所述第二连接器21中各增加至少2N个引脚，具体为：在所述第一连接器12增加至少N个所述第一引脚121和至少N个所述第二引脚122，在所述第二连接器21增加至少N个所述第三引脚211和至少N个所述第四引脚212。
其中，所述灯板1中，N为位于所述第一连接器12附近的所述目标灯区11的数量，即因为所述第一连接器12及所述第一连接器12的连接线而导致所述目标灯区11的灯珠的连接线无法布置。当所述灯板1包括多个所述第一连接器12时，各所述第一连接器12附近均可能存在所述目标灯区11。
在本申请的实施例中，第一连接器12的定义包含与驱动芯片连接的阴极引脚、各所述灯珠工作的正极电压VLED、本申请实施例中增加的2N个引脚。在图3所示的实施例中，所述灯板1可以包括80个灯区，每个灯区均连接至所述第一连接器12，因此，所述第一连接器12包括80个阴极引脚，VLED的电流要求VLED的连接线不少于15个引脚，在上述95个引脚的基础上，图3所示的实施中的所述第一连接器12增加所述第一引脚121和所述第二引脚122，即所述第一连接器12至少包括97个引脚。引脚过多时，所述第一连接器12的加工难度大、可靠性较低，可以将所述第一连接器分成多个分连接器。即本申请实施例中所述的第一连接器12和所述第二连接器21均可以包括一个或一个以上的连接器，具体连接器的数量根据实际需要设置，本申请实施例对连接器的数量不作限定。
如图5所示的实施例示出所述显示装置的背光驱动电路，所述显示装置可以包括多个所述灯板1和一个所述驱动板2，例如包括四个所述灯板1，四个所述灯板1均与所述驱动板2连接。具体地，所述灯板1的所述第一连接器12与所述驱动板2的所述第二连接器21连接，所述第二连接器21与所述驱动板2的驱动芯片22连接，形成所述显示装置的背光驱动电路。
图6所示的实施例中，所述显示装置可以为电视机的显示模组框图，所述显示装置可以包括16个所述灯板1和两个所述驱动板2，每个所述灯板1均包括两个所述第一连接器12，每个所述灯板1包括112个所述灯区，所述灯板1的基板为单层PCB板，所述基板设置有两个用于安装所述第一连接器12的安装槽，设置所述安装槽后，使得所述灯板1的112个所述灯区中的一部分为所述目标灯区11，即部分灯区存在连接线无法布置的灯珠。采用以上各实施例所述的结构，在所述第一连接器12和所述驱动板2的所述第二连接器增加引脚，能够实现单层PCB板中所述目标灯区11的连接线的布置，降低所述灯板1的成本。
本申请实施例中还提供一种电子设备，所述电子设备包括以上任一实施例所述的显示装置，例如，所述显示装置可以为电视、显示器等显示设备。
本申请的实施例中，通过在所述灯板1的所述第一连接器12以及所述驱动板2的所述第二连接器21原有结构的基础上增加2N个引脚，将所述第一连接器12的2N个引脚与所述第二连接器21的2N个引脚一一对应连接，并将所述灯板1中各所述目标灯区11的所述第一灯珠111与所述第二灯珠112分别连接至所述第一连接器12的所述引脚，使得连接线无法布置的各所述目标灯区11的所述第一灯珠111和所述第二灯珠112通过所述驱动板2的所述第二连接器21连接，使得在所述灯板1为单层PCB板时仍然能够实现所述灯区包括多个灯珠。
以上所述，仅为本申请实施例的具体实施方式，但本申请实施例的保护范围并不局限于此，任何在本申请实施例揭露的技术范围内的变化或替换，都应涵盖在本申请实施例的保护范围之内。因此，本申请实施例的保护范围应以所述权利要求的保护范围为准。
