Description

一种曲面显示面板及曲面显示装置
【技术领域】
本发明涉及显示面板技术领域,特别涉及一种曲面显示面板 和曲面显示装置。
【背景技术】
在曲面(Curved)薄膜场效应晶体管液晶显示器(TFT-LCD, Thin Film Transistor-Liquid Crystal Display) 领域中, 通常情况 下, 显示面板像素会以红绿蓝 (RGB) 的方式排列, 通过分别调 控 RGB 灰度实现不同色彩的显示, 若在画素中加入白色画素, 使其排列成为白红绿蓝 (WRGB), 这样在显示的时候能显示更 丰富的色彩。
在制作曲面显示器的时候, 通常的, 栅极(Gate)扫描线 101 平行于曲面显示面板长边 100a (即平行于曲面的曲线边), 而数 据 (Data) 线 102 垂直于曲面显示面板长边 100a, 且每个像素 (Pixel) 11 的长边垂直于曲面显示面板长边 100a, 像素 11 的短 边平行于曲面显示面板长边 100a (即每个像素 11 为竖直排列), 可参考图 la, 图 la以一个像素 11 为例, 对现有的曲面 TFT-LCD 的像素结构进行说明示意, 其中, 100b 为曲面显示面板短边, lib为像素短边。 但是, 将 WRGB 四个像素在同一的竖直方向上排列, 会造 成数据线 102较多, 从而引起充电不足而出现一些显示不良; 由 于上基板 12 (彩色滤光片 (CF, color filter ) 基板)、 下基板 13 ( TFT基板) 会以显示面板中心为基点, 在水平方向往左和往右 两边逐渐产生相对位移 (shift ) , 这就使得显示面板左右两边上 下基板产生较大的相对位移, 可一并参考图 l b和图 l c, 均为现 有曲面显示器的结构设置简图; 并且由于上下基板相对位移较大 使黑矩阵遮光多而造成开口率会下降, 从而引起左右这两个区域 亮度降低,看起来整个显示面板在左右两个区域就会有明显的黑 团, 如图 l c 所示。 由于整个上基板相对于下基板并不是同时往 左或者同时往右产生相对位移, 而是以中间为基点, 往左右两边 都往外扩, 也就说是往相反方向外扩, 在相对位移较大的时候, 其漏光颜色会有所不同, 从而会造成左右两边的黑团处会存在较 大的色偏。
因此,有必要提出一种新的技术方案, 以解决上述技术问题。 【发明内容】

图 6为本发明提供的曲面显示装置的结构示意图。 【具体实施方式】
请参照图式, 其中相同的组件符号代表相同的组件, 本发明 的原理是以实施在一适当的运算环境中来举例说明。 以下的说明 是基于所例示的本发明具体实施例, 其不应被视为限制本发明未 在此详述的其它具体实施例。
请参考图 2, 图 2为本发明提供的曲面显示面板 200 的结构 示意图。 所述曲面显示面板 200 包括设置于所述曲面显示面板 200 内的像素结构、 以及向所述像素结构提供数据信号的数据线 201;
所述曲面显示面板 200 的四条边框由两条第一边框 200a和 两条第二边框 200b 组成, 所述第一边框 200a 和所述第二边框 200b相邻, 所述第一边框 200a为曲线边框, 所述第一边框 200a 的长度大于所述第二边框 200b 的长度, 其中, 所述像素结构包 括:
两个以上像素单元 21 ;
每个所述像素单元 21 包括四个子像素, 所述四个子像素为 一红色子像素 R、 一绿色子像素 G、 一蓝色子像素 B 以及一白色 子像素 W ;
每个所述像素单元 21 中的四个子像素呈 2 X 2矩阵排列, 每 个所述像素单元 21 中同一行的两个子像素连接于同一数据线; 每个所述子像素呈矩形设置, 每个所述子像素包括长边 21 a 和短边 21 b, 其中, 每个所述子像素的长边 21 a与所述第一边框 200a平行设置,每个所述子像素的短边 21 b与所述第二边框 200b 平行设置, 且每个所述子像素的长边 21 a 垂直于所述第二边框 200b, 每个所述子像素的短边 21 b垂直于所述第一边框 200a。
可以理解的是, 图 2所示仅以一个像素单元 21 对所述曲面 显示面板 200 的像素结构进行示意说明, 不构成对本发明的限 定。
可结合参考图 3, 图 3为所述曲面显示面板 200 的另一结构 示意简图, 其中, 所述第一边框 200a 为曲线边框, 即为所述曲 面显示面板 200 的长边, 所述第二边框 200b为所述曲面显示面 板 200 的短边, 且所述第二边框 200b垂直于所述第一边框 200a 所在的平面 A。
进一歩的, 如图 3所示, 所述子像素设置于所述曲面显示面 板 200 内, 子像素的长边 21 a垂直于所述第二边框 200b, 且所 述子像素的长边 21 a平行于平面 A ; 所述子像素的短边 21 b平行 于所述第二边框 200b, 且所述子像素的短边 21 b 垂直于所述第 一边框 200a所在的平面 A ; 可以理解的是, 结合图 2和图 3, 由 上述分析可知, 由于所述第一边框 200a 为曲线边框, 但是子像 素的长边 21 a的长度远小于所述曲线边框的长度, 因此, 本发明 实施例中, 可将所述子像素的长边 21 a看作平行于曲线边框 (即 第一边框 200a ) 设置, 可将所述子像素的短边 21 b 看作垂直于 所述第一边框 200a设置。
更进一歩的, 请参考图 2, 所述曲面显示面板 200包括扫描 线 202, 所述扫描线 202 与所述第一边框 200a垂直设置, 且与 所述第二边框 200b平行设置。 所述数据线 201 与所述第二边框 200b垂直设置, 且与所述第一边框 200a平行设置。 也就是说, 所述扫描线 202与所述子像素的短边 21 b平行设置,所述数据线 201 与所述子像素的长边 21 a平行设置。 可一并参考图 4, 图 4 为本发明实施例中所述像素单元和所述数据线 201、 所述扫描线 202的连接关系示意图, 如图 4所示, 以两个像素单元与所述数 据线 201、 所述扫描线 202的连接关系进行示意, 不构成对本发 明的限定。
基于此, 以下对如图 2所示的曲面显示面板 200结构进行分 析说明:
第一方面, 所述曲面显示面板 200 中每个所述像素单元 21 包括四个子像素 (WRGB ) , 每个所述像素单元 21 中的四个子像 素呈 2 X 2矩阵排列, 每个所述像素单元 21 中同一行的两个子像 素连接于同一数据线。 也就是说, 两个子像素共用一条数据线进 行驱动, 如图 4所示, 相对于如图 1所示的像素结构, 每个像素 单元数据线的数量减少了一半, 从而避免因数据线多引起充电不 足而出现显示画面不均匀的问题, 同时大大节省了成本。
在某些实施方式中,所述曲面显示面板 200可基于以下方式 分别控制扫描线 202和数据线 201进行驱动: 假设, 所述曲面显 示面板 200为全高清 (FHD, Full High Definition ) 屏幕, 其分 辨率为 1920 * 1080, 即所述曲面显示面板 200 需要 1080 条扫描 线 202, 这些扫描线 202需要在一帧的时间内依次开关一遍, 每 打开一次的时候, 对应的数据线 201 输入数据信号 (即电压信 号), 如图 1 所示的像素结构, 在一帧内, 控制一个像素单元的 扫描线打开后, 不同的数据线对应的向四个子像素输入不同的数 据信号; 而图 4所示的像素结构, 在同一帧内, 扫描线 202a先 打开, 白色子像素 W充电, 与其相连接的数据线 201 向其输入 数据信号; 其后扫描线 202b打开, 蓝色子像素 B充电, 与其相 连接的数据线 201 向其输入数据信号, 其他子像素类似方式进行 驱动, 此处不再具体描述。
第二方面, 相比于如图 1所示的曲面显示面板, 本发明实施 例中, 将每个所述子像素横向排列, 即每个子像素的长边 21a与 所述第一边框 200a平行设置, 每个所述子像素的短边 21b与所 述第二边框 200b平行设置, 如图 2和图 3所示, 所述曲面显示 面板 200 这样设置可以大大减轻曲面显示面板两边黑团区域的 面积, 从而可以减轻曲面显示面板左右两区域的色偏, 以减轻曲 面显示面板显示画面不均匀的问题。
以下对现有的曲面显示面板结构 (如图 la所示) 的开口区 与本发明实施例提供的曲面显示面板 200结构 (如图 2所示) 的 开口区进行对比分析:
如图 la所示曲面显示面板结构, 栅极扫描线 101 平行于曲 面显示器长边 100a (即平行于曲线边框), 而数据线 102垂直于 曲面显示面板长边 100a,且每个子像素长边 11a垂直于曲面显示 面板长边 100a, 其中, 子像素长边 11a 的长度为 m, 短边 lib 的长度为 n。
根据玻璃受力分析, 相对位移从显示面板中心在曲面显示器 长边 100a 方向往左右两边逐渐扩大, 并且左右两边位移方向相 反, 可参考图 lb和图 lc。 根据相对位移的方向和大小, 假如一 个子像素的位移量为 (s) urn, 那么一个子像素所造成的被遮光 面积 (开口区损失) 就是 (mx s ) um2 0
如图 2所示曲面显示面板结构, 每个子像素的长边 21a与所 述第一边框 200a平行设置, 每个所述子像素的短边 21 b与所述 第二边框 200b平行设置, 且每个所述子像素的长边 21 a垂直于 所述第二边框 200b, 每个所述子像素的短边 21 b 垂直于所述第 一边框 200a。 所述扫描线 202与所述第一边框 200a垂直设置, 且与所述第二边框 200b平行设置, 所述数据线 201 与所述第二 边框 200b垂直设置, 且与所述第一边框 200a平行设置。
可以理解的是, 在同样的位移量下, 同一固定点损失的开口 区就为(n x s) um2, 然而, m的值是远远大于 n的值, 故采用本 发明提供的曲面显示面板结构开口区损失是远远小于传统的曲 面显示面板的设计, 这样就可以最大化的减轻由于开口率损失较 大而造成的显示不良, 即可以大大减轻曲面显示面板两边黑团区 域的面积, 同时可以减轻曲面显示面板左右两区域的色偏, 以减 轻曲面显示面板显示画面不均匀的问题。
第三方面, 相比于如图 1所示的曲面显示面板, 本发明实施 例中, 如图 5 a所示, 为所述曲面显示面板 200另一结构示意图, 其包括两个数据驱动电路 203, 其分别设置在相应的所述第一边 框 200a 的外侧, 其中两个所述数据驱动电路 203 同时向同一所 述数据线 201输入数据信号, 以减少数据线 201末端信号衰减严 重造成的图像信号失真。
优选的, 设置在一所述第一边框 200a 外侧的数据驱动电路 203 与设置在另一所述第一边框 200a 外侧的数据驱动电路 203 同时连接同一数据线 201, 其中, 连接同一数据线的两个数据驱 动电路 203 同时向所述同一数据线输入大小相同的数据信号, 并 且, 所述数据驱动电路 203 可以采用覆晶薄膜 (COF, Chip On Film ) 封装而成, 以使得该数据线 201对向同一行子像素提供的 数据信号进行补给, 避免了现有数据线末端信号衰减的问题。
优选的, 如图 5b所示, 为所述曲面显示面板 200 另一结构 示意图, 其包括两个扫描驱动电路 204, 其分别设置在相应的所 述第二边框 200b 的外侧, 其中两个所述扫描驱动电路 204 同时 向同一所述扫描线 202输入扫描信号, 以减少扫描线 202 因充电 不足而引起的显示亮度不均匀的问题。
设置在一所述第二边框 200b外侧的扫描驱动电路 204 与设 置在另一所述第二边框 200b外侧的扫描驱动电路 204 同时连接 同一扫描线 202,其中,连接同一扫描线的两个扫描驱动电路 204 同时向所述同一扫描线输入大小相同的扫描信号, 并且所述扫描 驱动电路 204可以采用覆晶薄膜封装而成, 以使得该扫描线 202 对向同一列子像素提供的开关控制信号进行补给,避免了现有扫 描线因充电不足而引起的显示亮度不均匀的问题。
可以理解的是, 图 2、 图 5a以及图 5b仅示出了一个数据线 201和数据驱动电路 203 的连接关系, 一个扫描线 202和扫描驱 动电路 204 的连接关系进行分析说明, 其他数据线和扫描线也可 以参考设置, 此处举例不构成对本发明的限定。
由上述可知, 本发明提供的曲面显示面板 200, 像素单元 21 中的四个子像素呈 2 X 2矩阵排列, 每个像素单元 21 中同一行的 两个子像素连接于同一数据线, 从而数据线 201 的数量减少了一 半, 避免因数据线多引起充电不足而出现显示画面不均匀的问 题, 同时大大节省了成本; 并且, 每个子像素的长边 21 a与曲面 显示面板的长边框 200a平行设置, 每个子像素的短边 21 b与曲 面显示面板的短边框 200b 平行设置, 可以大大减轻曲面显示面 板 200两边黑团区域的面积, 从而可以减轻曲面显示面板 200左 右两区域的色偏, 以减轻曲面显示面板 200显示画面不均匀的问 题。 进一歩的, 连接同一数据线 201 的两个数据驱动电路同时向 所述同一数据线 201输入大小相同的数据信号, 以使得该数据线 201对向同一行子像素提供的数据信号进行补给, 避免了现有数 据线末端信号衰减的问题。连接同一扫描线 202 的两个扫描驱动 电路同时向所述同一扫描线 202输入大小相同的扫描信号, 以使 得该扫描线 202 对向同一列子像素提供的开关控制信号进行补 给,避免了现有扫描线因充电不足而引起的显示亮度不均匀的问 题。
为便于更好的实施本发明实施例提供的曲面显示面板, 本发 明实施例还提供一种包含所述曲面显示面板的曲面显示装置。其 中名词的含义与上述曲面显示面板中相同, 具体实现细节可以参 考曲面显示面板实施例中的说明。

可以理解的是, 图 2所示仅以一个像素单元 21 对所述曲面 显示面板 200 的像素结构进行示意说明, 不构成对本发明的限 定。
可结合参考图 3, 图 3为所述曲面显示面板 200 的另一结构 示意简图, 其中, 所述第一边框 200a 为曲线边框, 即为所述曲 面显示面板 200 的长边, 所述第二边框 200b为所述曲面显示面 板 200 的短边, 且所述第二边框 200b垂直于所述第一边框 200a 所在的平面 A。 进一歩的, 如图 3所示, 所述子像素设置于所述曲面显示面 板 200 内, 子像素的长边 21 a垂直于所述第二边框 200b, 且所 述子像素的长边 21 a平行于平面 A ; 所述子像素的短边 21 b平行 于所述第二边框 200b, 且所述子像素的短边 21 b 垂直于所述第 一边框 200a所在的平面 A ; 可以理解的是, 结合图 2和图 3, 由 上述分析可知, 由于所述第一边框 200a 为曲线边框, 但是子像 素的长边 21 a的长度远小于所述曲线边框的长度, 因此, 本发明 实施例中, 可将所述子像素的长边 21 a看作平行于曲线边框 (即 第一边框 200a ) 设置, 可将所述子像素的短边 21 b 看作垂直于 所述第一边框 200a设置。
更进一歩的, 请参考图 2, 所述曲面显示面板 200包括扫描 线 202, 所述扫描线 202 与所述第一边框 200a垂直设置, 且与 所述第二边框 200b平行设置。 所述数据线 201 与所述第二边框 200b垂直设置, 且与所述第一边框 200a平行设置。 也就是说, 所述扫描线 202与所述子像素的短边 21 b平行设置,所述数据线 201 与所述子像素的长边 21 a平行设置。 可一并参考图 4, 图 4 为本发明实施例中所述像素单元和所述数据线 201、 所述扫描线 202的连接关系示意图, 如图 4所示, 以两个像素单元与所述数 据线 201、 所述扫描线 202的连接关系进行示意, 不构成对本发 明的限定。
基于此, 以下对如图 2所示的曲面显示面板 200结构进行分 析说明:
第一方面, 所述曲面显示面板 200 中每个所述像素单元 21 包括四个子像素 (WRGB ) , 每个所述像素单元 21 中的四个子像 素呈 2 X 2矩阵排列, 每个所述像素单元 21 中同一行的两个子像 素连接于同一数据线。 也就是说, 两个子像素共用一条数据线进 行驱动, 如图 4所示, 相对于如图 1所示的像素结构, 每个像素 单元数据线的数量减少了一半, 从而避免因数据线多引起充电不 足而出现显示画面不均匀的问题, 同时大大节省了成本。
对于如图 4所示的像素结构, 在同一帧内, 扫描线 202a先 打开, 白色子像素 W充电, 与其相连接的数据线 201 向其输入 数据信号; 其后扫描线 202b打开, 蓝色子像素 B充电, 与其相 连接的数据线 201 向其输入数据信号, 其他子像素类似方式进行 驱动, 此处不再具体描述。
第二方面, 相比于如图 1所示的曲面显示面板, 本发明实施 例中, 将每个所述子像素横向排列, 即每个子像素的长边 21 a与 所述第一边框 200a平行设置, 每个所述子像素的短边 21 b与所 述第二边框 200b平行设置, 如图 2和图 3所示, 所述曲面显示 面板 200 这样设置可以大大减轻曲面显示面板两边黑团区域的 面积, 从而可以减轻曲面显示面板左右两区域的色偏, 以减轻曲 面显示面板显示画面不均匀的问题。
以下对现有的曲面显示面板结构 (如图 l a所示) 的开口区 与本发明实施例提供的曲面显示面板 200结构 (如图 2所示) 的 开口区进行对比分析:
如图 l a所示曲面显示面板结构, 根据玻璃受力分析, 相对 渐扩大, 并且左右两边位移方向相反, 可参考图 l b和图 l c。 根 据相对位移的方向和大小, 假如一个子像素的位移量为 (s ) um, 那么一个子像素所造成的被遮光面积 (开口区损失) 就是 (m x s ) um
如图 2所示曲面显示面板结构, 在同样的位移量下, 同一固 定点损失的开口区就为 n x s) um2, 然而, m 的值是远远大于 n 的值, 故采用本发明提供的曲面显示面板结构开口区损失是远远 小于传统的曲面显示面板的设计, 这样就可以最大化的减轻由于 开口率损失较大而造成的显示不良, 即可以大大减轻曲面显示面 板两边黑团区域的面积, 同时可以减轻曲面显示面板左右两区域 的色偏, 以减轻曲面显示面板显示画面不均匀的问题。
第三方面, 相比于如图 1所示的曲面显示面板, 本发明实施 例中, 如图 5 a所示, 为所述曲面显示面板 200另一结构示意图, 其包括两个数据驱动电路 203, 其分别设置在相应的所述第一边 框 200a 的外侧, 其中两个所述数据驱动电路 203 同时向同一所 述数据线 201输入数据信号; 进一歩的, 设置在一所述第一边框 200a外侧的数据驱动电路 203 与设置在另一所述第一边框 200a 外侧的数据驱动电路 203 同时连接同一数据线 201, 其中, 连接 同一数据线的两个数据驱动电路 203 同时向所述同一数据线输 入大小相同的数据信号, 并且, 所述数据驱动电路 203可以采用 覆晶薄膜 COF 封装而成, 以使得该数据线 201 对向同一行子像 素提供的数据信号进行补给,避免了现有数据线末端信号衰减的 问题。 如图 5b所示, 为所述曲面显示面板 200 另一结构示意图, 其包括两个扫描驱动电路 204, 其分别设置在相应的所述第二边 框 200b 的外侧, 其中两个所述扫描驱动电路 204 同时向同一所 述扫描线 202输入扫描信号; 进一歩的, 设置在一所述第二边框 200b外侧的扫描驱动电路 204 与设置在另一所述第二边框 200b 外侧的扫描驱动电路 204 同时连接同一扫描线 202, 其中, 连接 同一扫描线的两个扫描驱动电路 204 同时向所述同一扫描线输 入大小相同的扫描信号, 并且所述扫描驱动电路 204可以采用覆 晶薄膜封装而成, 以使得该扫描线 202对向同一列子像素提供的 开关控制信号进行补给,避免了现有扫描线因充电不足而引起的 显示亮度不均匀的问题。
可以理解的是, 图 2、 图 5 a以及图 5b仅示出了一个数据线 201和数据驱动电路 203 的连接关系, 一个扫描线 202和扫描驱 动电路 204 的连接关系进行分析说明, 其他数据线和扫描线也可 以参考设置, 此处举例不构成对本发明的限定。
由上述可知, 本实施例提供的曲面显示装置 600, 包含如上 所述的曲面显示面板 200, 像素单元 21 中的四个子像素呈 2 X 2 矩阵排列, 每个像素单元 21 中同一行的两个子像素连接于同一 数据线, 从而数据线的数量减少了一半, 避免因数据线多引起充 电不足而出现显示画面不均匀的问题, 同时大大节省了成本; 并 且, 每个子像素的长边 21 a与曲面显示面板的长边框 200a平行 设置, 每个子像素的短边 21 b与曲面显示面板的短边框 200b平 行设置, 可以大大减轻曲面显示面板 200两边黑团区域的面积, 从而可以减轻曲面显示面板 200左右两区域的色偏, 以减轻曲面 显示面板 200显示画面不均匀的问题。 进一歩的, 连接同一数据 线 201 的两个数据驱动电路 203同时向所述同一数据线 201输入 大小相同的数据信号, 以使得该数据线 201对向同一行子像素提 供的数据信号进行补给, 避免了现有数据线末端信号衰减的问 题。连接同一扫描线 202 的两个扫描驱动电路 204 同时向所述同 一扫描线 202输入大小相同的扫描信号, 以使得该扫描线 202对 向同一列子像素提供的开关控制信号进行补给,避免了现有扫描 线因充电不足而引起的显示亮度不均匀的问题。
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, 可以参见上文相关的详细描述, 此处不 再赘述。
