第一实施例:如图1所示,图1为本申请提供的一种显示设备的分流电路,分流电路包括至少一个扫描电压输出模块,至少一个扫描电压输出模块包括目标扫描电压输出模块,目标扫描电压输出模块包括:干流子模块10,用于接收输入的显示设备扫描电压,并输出至分流子模块;分流子模块20,与干流子模块电连接,用于接收干流子模块输出的显示设备扫描电压并进行分流输出。
由于在通过扫描电压控制显示装置进行显示时,会存在有亮块和低灰阶画面的暗区,既一种高对比耦合现象,出现这种现象的原因是瞬时电流的增大,从而使得扫描电压处的电位受到显示设备中较亮的区域的影响进而使得电位变高了,导致同行蓝色区域的LED两端,跨压减小,从而导致相比于非显示设备的同一行的显示区域画面偏暗。此外,正因为在mini-LED技术中,使用的LED数量远超于一般性的显示设备,因此显示设备中画面偏暗的区域面积也就越大,为此,为了解决这一问题,可以在扫描电压出入的干流位置处,添加一个分流子模块,用于降低因为电流瞬时增大,而增大的电位,从而消除因为电位过高,画面出现偏暗的问题。
即,本实施例提供的一种显示设备的分流电路,通过在干流电压端的 基础之上,添加一个分流子模块,通过分流的功能,减小干流电压的输入端因为电流瞬时增大而增加的电位,进而避免显示设备的画面出现偏暗的情况,保证了显示设备的画面明亮度。
第二实施例:如图2所示,图2为本申请提供的一种显示设备的分流电路,干流子模块包括:扫描电压输入端101(V Scan),扫描电压输入端通过第一MOS管103与预设的第一控制电压输入端102(V in(n)n=1,,3……)连接,第一MOS管103包括第一连接端口、第二连接端口以及第三连接端口,其中,第一连接端口与扫描电压输入端连接101,第二连接端口与第一控制电压输入端102连接。
本实施例提供了一种干流子模块的内部结构,可以通过在扫描电压输入端上添加控制电压,再经过MOS管,调节输入的扫描电压。
第三实施例:如图3所示,图3为本申请提供的一种显示设备的分流电路,分流子模块包括:
第二控制电压输入端202,第二控制电压输入端202与扫描电压输入端101通过第二MOS管203连接,第二MOS管203包括第四连接端口、第五连接端口以及第六连接端口,其中,第四连接端口与扫描电压输入端101连接,第五连接端口与第二控制电压输入端202连接,第六连接端口与第三连接端口连接形成目标扫描电压输出模块的电压输出端。
根据上述实施例可得,由于仅作为干流输入的扫描电压,可能存在由于瞬时电流过大,进而导致电位变高的问题,这里通过添加一个额外的控制电压,以及另一个MOS管,使得额外的控制电压与MOS管形成串联,在将串联起来的MOS管与额外的控制电压,与上述实施例中的干流子模块进行并联,从而达到对干流中的电压进行分流的目的。当瞬时电流增大时,可以通过分流的作用,避免扫描电压的输入端电位过大的问题。
第四实施例:如图4所示,图4为本申请提供的一种显示设备的分流电路,分流子模块还包括:分流电阻204,设置于第四连接端口与扫描电压输入端101之间。
根据上述实施例可得,当添加了额外的控制电压以及第二根MOS管之后,可以对原干流路线进行分流,在未添加该分流电阻之前,分流路线上的MOS管电,可能在进行分流工作时,电压可能出现瞬时变化,导致电压突然增大损坏该分流路线上的MOS管。因此,该分流电阻可以有效的避免分流路线上的MOS因为瞬时电压增大,从而导致损坏的问题。
此外,将该分流电阻连接至分流路线中之后,由于分流模块与干流模块为一种并联状态,因此整体负载阻抗不会变化太大,因此能更好控制电位的变化,提高了电位控制的精细度。
第五实施例:如图5所示,图5为本申请提供的显示设备的分流电路,分流电路还包括:数据电压输入端,数据电压输入端30通过发光二极管与目标扫描电压输出模块连接。
根据上述实施例可以得到干流子模块与分流子模块的内部结构,且,干流子模块以及分流子模块构成了该目标扫描电压输出模块。因此,如图5所示,当第一MOS管103的第三接口以及第二MOS管203的第六接口连接之后,可以得到该目标扫描电压输出模块的最终的一个电压输出端,该电压输出端即为完成了电位分流的一个电压输出端,当此电压输出端与数据电压输入端30和发光二极管串联之后,便可以控制发光二极管的亮度,避免出现亮度偏暗的发光二极管。
第六实施例:如图6所示,图6为本申请提供的显示设备的分流电路,其特征在于,分流电路包括至少一个扫描电压输出模块,包括:至少一个扫描电压输出模块中的每个扫描电压输出模块,均包括目标扫描电压输出模块,每个扫描电压输出模块之间互不相连,每个扫描电压输出模块分别通过多个发光二极管分别与一个预设的数据电压输入端串联,一个发光二极管对应一个扫描电压输出模块。本实施例提供了一种控制显示设备中,一种纵向的电路排布结构,可以避免纵向的发光二极管出现亮度较暗的情况。
第七实施例:如图7所示,图7为本申请提供的显示设备的分流电路, 分流电路还包括:多个数据电压输入端,多个数据电压输入端之间互不相连,多个数据电压输入端中的任意一个数据电压输入端均通过多个发光二极管分别与每个扫描电压输出模块串联,一个发光二极管对应一个扫描电压输出模块。
本实施例提供了一种显示面板内部的一种多个目标扫描电压输出模块与多个数据电压输入端的连接方式,该连接方式可以使得显示设备中,每一个纵列及每一个行列中的发光二极管均不会出现亮度较暗的情况。
第八实施例:如图8所示,图8为本申请提供的显示设备的分流电路,其特征在于,分流电路包括至少一个扫描电压输出模块,包括至少一个扫描电压输出模块中的部分扫描电压输出模块包括目标扫描电压输出模块,部分扫描电压输出模块之间互不相连,部分扫描电压输出模块分别通过多个发光二极管分别与一个预设的数据电压输入端串联,一个发光二极管对应一个扫描电压输出模块。
本申请实施例中提供的目标扫描电压输出模块与上述实施例中不同的是,当显示设备中出现多个扫描电压输出模块时,多个扫描电压输出模块中仅有部分扫描电压输出模块为本申请实施例中提及的目标扫描电压输出模块。这样做的目的是,若多个扫描电压输出模块中其他的扫描电压输出模块为普通模块时,可以减少显示设备的制作成本。
例如:如图8所示,可以在一个显示面板中,显示设备最靠下的位置处的扫描电压输出模块设置为普通的扫描电压输出模块,这样仅会使得显示设备中,最下方的显示区域出现亮度较暗的问题。由于,用户在进行显示设备的使用时,大多数的时间,用户的视线通常聚焦于画面的中心区域,因此,显示设备下方出现亮度较暗的区域时,用户难以发现,这样既不会破坏用户的视觉体验,同时保证了显示设备大部分区域的亮度,同时能够一定程度上的减少制造成本。需要说明的是,此排布方式仅为显示设备中,一个纵向的排布方式。
第九实施例:如图9所示,图9为本申请提供的显示设备的分流电路, 其特征在于,分流电路还包括:
多个数据电压输入端,多个数据电压输入端之间互不相连,多个数据电压输入端中的任意一个数据电压输入端均通过多个发光二极管分别与至少一个扫描电压输出模块中的每个扫描电压输出模块串联,一个发光二极管对应一个扫描电压输出模块。
如上述实施例中的目的相同,本实施例提供了一种多个扫描电压输出模块中仅部分的扫描电压输出模块为目标扫描电压输出模块的排布方式,可以通过此排布方式,对显示设备中的发光二极管进行排布,从而达到与上述实施例中相同的技术效果。
此外,本申请实施例还提供了一种显示设备,该显示设备可以搭载上述实施例中任意一项实施例中描述的显示设备的分流电路。
在上述实施例中,对各个实施例的描述都各有侧重,某个实施例中没有详述的部分,可以参见上文针对其他实施例的详细描述,此处不再赘述。以上对本申请实施例所提供的一种显示设备的分流电路进行了详细介绍,本文中应用了具体个例对本申请的原理及实施方式进行了阐述,以上实施例的说明只是用于帮助理解本申请的方法及其核心思想;同时,对于本领域的技术人员,依据本申请的思想,在具体实施方式及应用范围上均会有改变之处,综上,本说明书内容不应理解为对本申请的限制。
