Description

显示面板组件及其调节方法、 显示装置
【技术领域】
本发明涉及显示装置领域, 更具体的说, 涉及一种显示面板组件及其调节 方法、 显示装置。
【背景技术】
如图 1所示为现有的一种液晶显示面板组件, 其包括: 显示面板 100、 设置 在显示面板 100上的显示区域 110、 设置在显示面板 100上的扇出 (fanout ) 区 域 120、 设置在面板边缘的封装有驱动 IC140的薄膜覆晶 130以及 PCB150; 其 中, 显示区域 110设置有多条第一数据线 111 , 扇出区域 120设置有多条第二数 据线 121与所述第一数据线 111连接, 薄膜覆晶 130上设置有多条第三数据线 131将所述第二数据线与所述驱动 IC140进行连接。 如图 1所示, 显示面板 100 扇出区域 120第二数据线 121与第一数据线 111的连接点由于距离驱动 IC140 的距离不同, 导致第二数据线 121 的长度不同而阻抗各不相同, 由于阻抗对信 号延迟的影响, 离 IC的距离较近的第二数据线的信号失真小, 而离 IC距离较 远的第二数据线的信号失真较大, 这样会引起诸如左中右亮度差异或色偏等问 题。 尤其是对于大尺寸的液晶面板来说, 加之驱动 IC的集成度越来越高, 面板 使用 IC的数量减少, 此问题更明显。
为了解决此问题, 如图 2所示, 现有技术往往是在面板的扇出区域进行绕 线补偿, 即离 IC的距离越近的数据线在扇出区域, 对第二数据线 121的铺设路 径进行加长, 通过设置折弯部 122使其形成绕线, 而在离 IC距离越远的数据线 进行较少的绕线。 但这样的方案使得面板的扇出区域面积较大, 不利于面板的 成本控制及窄边框的实现。
【发明内容】
本发明所要解决的技术问题是提供一种可实现较窄边框且显示效果优异的 显示面板组件及其调节方法、 显示装置。
本发明的目的是通过以下技术方案来实现的:
一种显示面板组件, 包括:

优选的, 所述功能电路以及与所述功能电路的输出端连接的可调电阻组集 成在一个驱动 IC内。 这样的集成度高, 成本低廉。
优选的, 所述显示面板组件还包括一设置在所述显示面板扇出区边缘的薄 膜覆晶, 所述驱动 IC设置在所述薄膜覆晶上。
优选的, 所述驱动 IC集成在所述显示面板的玻璃基板上。 将取得 IC集成 在玻璃基板上, 这种设置方式可以减小 LCD模组的整体体积。
优选的, 所述控制电路包括用于写入数据的写入引脚, 所述控制电路通过 所述写入引脚获得预设的可调电阻组的阻值的控制信号, 以对所述可调电阻组 进行调节。
优选的, 所述控制电路集成在所述驱动 IC内, 所述写入引脚设置在所述驱 动 IC上。 这种方式集成度高, 可避免不必要的配件, 节约生产成本。
优选的, 所述可调电阻组为数位电阻组, 所述控制电路为数位控制电路。 使用数位电阻组及数位控制电路可以很好的实现控制调整, 实现比较筒单, 成 本较低。
优选的, 所述可调电阻组预设有多个与不同型号的显示面板所对应的可调 阻值。 这样的设置可以通过对应的几组控制信号控制即可, 控制方式筒便, 硬 件的实现也相对筒单, 成本较低。
一种显示面板组件的调节方法, 所述的显示面板组件包括:
显示面板, 其设置有显示区和扇出区, 所述显示区设置有多条第一数据线、 所述扇出区设置有具有多种长度的多条第二数据线与所述第一数据线连接; 驱动电路, 其包括功能电路以及与所述功能电路的输出端连接的可调电阻 组; 所述第二数据线通过所述可调电阻组耦合到所述功能电路的输出端;
所述的显示面板组件的调节方法包括以下步骤:
S1 , 调整可调电阻组的阻值, 以减小所述功能电路输出端到所述第一数据 线之间的连线的阻抗差异。
优选的, 所述控制电路包括用于写入数据的写入引脚, 所述步骤 S1中, 所 述控制电路通过写入引脚从 data信号中读取对应的控制信号, 解析后获得应设 的可调电阻组的阻值, 对所述可调电阻组进行自动可控调节。 这种方式不需要 对 TCON进行修改, 从而有效的节约产品的成本。
本发明由于通过可调电阻组以减小驱动电路中功能电路输出端到所述第一 数据线之间的连线的阻抗差异, 并通过控制电路对可调电阻组进行控制, 这样 避免了各条连线之间的信号延迟差异过大的情况, 使得显示面板可以实现色彩、 亮度均匀的优异显示。 同时, 由于在可调电阻组的设置, 就不需要在面板的扇 出区域对第二数据线进行路径加长(通过设置折弯部形成绕线) 的方式来减小 各条连线之间的阻抗差异以消除信号延迟差异, 使得面板的扇出区域的第二数 据的铺设路径可以更直接的以直线方式铺设, 这样就减小了扇出区域的高度, 使得液晶显示器可以达到更加窄的边框设计。 再者, 可调电阻的可调功能, 不 需要针对每个面板单独设置驱动 IC或者电阻, 在应用于不同型号面板时, 只需 要调节可调电阻组的阻值即可, 这样极大的减少了生产成本, 提高生产效率。

如图 3所示为本实施例提供的一种液晶显示面板组件,其包括:显示面板 100、 设置在显示面板 100上的显示区域 110、设置在显示面板 100上的扇出区域 120、 设置在显示面板 100边缘的封装有驱动 IC140的薄膜覆晶 130以及 PCB150。
其中, 显示区域 110设置有多条第一数据线 111 , 所述扇出区域 120设置有 多条具有多种长度的第二数据线 121与所述第一数据线 111连接; 在距离驱动 IC140较近的区域, 所述第二数据线 121的长度就越短, 第二数据线 121均是按 照直线路径铺设, 以尽可能的减小显示面板 100边缘的宽度, 这一更好的实现 显示装置的窄边框设计。 薄膜覆晶 130用于连接显示面板 100与 PCB150, 驱动 IC140封装在薄膜覆晶 130内, 驱动 IC140内集成了功能电路 142、 可调电阻组 145以及用于控制所述可调电阻组 145的控制电路 143, 同时, 驱动 IC140设置 有控制电路 143的写入引脚 144。 所述第二数据线 121通过所述可调电阻组 145 与所述驱动 IC140的功能电路 142的输出端进行耦合, 可调电阻组 145在控制 电路 143的控制之下, 通过调整可调电阻组 145 内的各个电阻的阻值, 以减小 功能电路 142的各个输出端到第一数据线 111之间的连线的阻抗差异, 避免应 用到显示装置后出现因各个连线的阻抗差异太大、 信号延迟造成亮度、 颜色在 显示面板 100上的各个区域显示具有差异的问题。
在本实施例中, 所述的可调电阻组 145为可调的数位电阻组, 对应的, 所述 的控制电路 143 则为数位控制电路, 数位电阻是比较精确的可调电阻, 同时数 位控制电路也是比较筒单的控制方式。 不过由于可调节电阻数量非常多, 调整 较为复杂, 因此, 在本实施例中, 针对几个型号的面板(比如大、 中、 小型面 板)预先设定好可调电阻组 145的几组阻值, 控制电路 143则仅根据对应的预 设好的型号直接在几组可调电阻组 145的阻值中选择即可, 控制电路 143 包括 用于写入数据的写入引脚 144,通过写入引脚 144获得预设的可调电阻组 145的 阻值的控制信号, 以对所述可调电阻组 145 进行调节。 本实施例以对应四款型 号的面板为例, 通过预设四组阻值, 当应用于其中一款面板时, 根据其型号, 在四组阻值中选择一组与当前面板所对应的阻值即可。 这样可以筒化控制电路 的控制, 四组阻值通过两个写入引脚 144即可实现选择控制(00、 01、 10、 11 ), 这样通过对应的几组控制信号控制即可, 控制方式筒便, 硬件的实现也相对筒 单, 成本较低。 从写入引脚写入的数据可以集成在数据(data )信号的冗余数位 中, 控制电路 143监控对应端口的数据( data )信号即可完成设置, 实现阻值的 自动可控选择, 这样, 就不需要对 TCON ( PCB150 )进行对应的硬件修改, 不 仅节省成本, 而且提高了薄膜覆晶 130的通用性。
当然, 控制电路 143以及可调电阻组 145也可以集成在薄膜覆晶 130上或者 另外集成一个具有控制电路 143以及可调电阻组 145的 IC。
本实施例同时提供了一种具备上述结构的显示面板组件的控制方法,如图 10 所示, 包括步骤: 50 , 从 data信号中的冗余数位中获取对应阻值的控制信号,
51 , 控制电路解析控制信号从而调整可调电阻组的阻值, 以减小所述功能电 路输出端到所述第一数据线之间的连线的阻抗差异。
实施例二
本实施例在上述实施例一的基础上, 通过对可调电阻组 145进行再次分组, 也就是说, 可调电阻组包括多个子可调电阻组, 这样可以针对各个子电阻组进 行调整, 每一组子电阻组可以调节为统一阻值, 这样不需要针对每一个功能电 路的输出端都设置不同的电阻,只需要通过一组相同阻值的电阻来缩小连线(功 能电路输出端到第一数据线 111 之间的连线)之间阻抗差异即可, 这样的设置 已经基本可以消除信号延迟或者说信号延迟十分微弱, 对显示效果的影响可以 忽略, 这种设置方式使得成本可以极大的降低。
实施例三
如图 4所示, 与实施例一不同的是, 本实施例通过在驱动 IC140内直接集成 电阻 144即可, 第三数据线 131通过电阻 144耦合到驱动 IC140的输出端, 第 三数据线 131 与面板上的扇出区域的第二数据线连接。 这种方式不需要设置专 门的控制电路来控制电阻, 但这种方式的驱动 IC只能适用于一款型号的面板。 同样的, 可以利用多个相同阻值的电阻组成为一组电阻组, 在所述驱动 IC140 内可集成多组阻值不同的电阻组。 这样不需要针对每一个驱动 IC140 的输出端 都设置不同的电阻, 只需要通过一组相同阻值的电阻来缩小阻抗差异即可, 这 样的设置已经基板可以消除信号延迟或者说信号延迟十分微弱, 对显示效果的 影响可以忽略, 这种设置方式使得成本可以极大的降低。
在上述实施例一、二、三中,所述驱动 IC140均是集成在薄膜覆晶 130上的, 但是, 所述驱动 IC140也是可以集成在显示面板 100的玻璃基板上的, 即 COG ( chip on glass ) 结构的面板, 这种结构的面板可以大幅减小 LCD模组的体积。
实施例四
如图 5所示为本实施例提供的一种液晶显示面板组件,其包括:显示面板 100、 设置在显示面板 100上的显示区域 110、设置在显示面板 100上的扇出区域 120、 设置在显示面板 100边缘的封装有驱动 IC140的薄膜覆晶 130以及 PCB。
其中, 显示区域 110设置有多条第一数据线 111 , 所述扇出区域 120设置有 多条具有多种长度的第二数据线 121 与所述第一数据线 111 连接, 距离驱动 IC140较近的区域, 所述第二数据线 121的长度就越短, 第二数据线 121均是按 照直线路径铺设。 以驱动 IC140中心区域的第二数据线 121a为例, 其长度远远 要小于驱动 IC140两侧区域的第二数据线 121b。
薄膜覆晶 130上设置有多条第三数据线 131 将所述第二数据线与所述驱动 IC140进行连接。 第三数据线 131中的一部分设置有一个或多个弯曲部 132, 所 述弯曲部 132使所述第三数据线 131的铺设路径加长,与越短的第二数据线 121 连接的第三数据线 131 其折弯部的数量就越多, 其长度也就越长, 因此, 其阻 抗也就越大。 以与第二数据线 121a连接的第三数据线 131a为例, 因为第三数据 线 131a的阻抗比较大, 使得其与所述第二数据线 121组成的整体连线的阻抗增 大, 相对于其他第三数据线 131b与第二数据线 121b组成的连线, 二者的阻抗 差异变得更小。
本实施例通过在薄膜覆晶 130上对部分第三数据线 131进行路径加长, 使得 驱动 IC140的输出端到所述第一数据线 111之间的连线(由第二数据线 121与 第三数据线 131 组成) 的阻抗差异, 这样避免了各条连线之间的信号延迟差异 过大的情况, 使得显示面板可以实现色彩、 亮度均匀的优异显示。 同时, 由于 在薄膜覆晶 130上进行绕线, 这样就不需要在面板的扇出区域对第二数据线进 行路径加长(通过设置折弯部形成绕线) 的方式来减小各条连线之间的阻抗差 异以消除信号延迟差异, 使得面板的扇出区域的第二数据的铺设路径可以更直 接的以直线方式铺设, 这样就减小了扇出区域的高度, 使得液晶显示器可以达 到更加窄的边框设计。
实施例五
如图 6所示为本发明提供另一种实施例, 在本实施例中, 第三数据线 131之 间的阻抗可以通过采用不同厚度的线路来达到, 其中, 较厚的第三数据线 131 其阻抗越小, 这样的第三数据线可以设置在驱动 IC的两侧区域。
实施例六
如图 7所述为本发明提供的另一种实施例, 在本实施例中, 通过对第三数据 线 131的线宽进行调整以使各条数据线的阻抗差异, 在与第二数据线 121连接 后使得整体连线之间的阻抗差异减小。
实施例七
如图 8所示, 本实施例结合了线路的宽度、 厚度以及线路路径, 也就是说, 在对线路路径进行绕线设置的同时, 对线路的宽度、 厚度也同时进行调整, 这 样, 可以在最小的面积里调整。
实施例八
如图 9所示, 本实施例通过在薄膜覆晶上集成电阻 133, 电阻 133之间的阻 抗不同, 分别连接到驱动 IC140的各个输出端上, 第三数据线通过电阻 133耦 合到驱动 IC140上。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明, 不能 认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通技 术人员来说, 在不脱离本发明构思的前提下, 还可以做出若干筒单推演或替换, 都应当视为属于本发明的保护范围。
