  • the present invention relates to the field of liquid crystal display technology, and in particular to a wide viewing angle panel and a display device.
  • the VA (Vertical Alignment) panel is a panel type that is currently used in high-end liquid crystal applications and belongs to a wide viewing angle panel.
  • VA mode liquid crystal panels often have a problem of color shift when viewed from a wide viewing angle.
  • the existing wide viewing angle panel divides the pixel into two regions. When the panel works, the brightness of one area (Main) is higher, and the brightness of another area (Sub) is lower, to pass the Two zones of different brightness are used to improve the wide viewing angle characteristics of the panel.
  • the penetration rate of the entire pixel will be greatly sacrificed, and the power consumption of the backlight is increased, which does not conform to the current concept of environmental protection and energy conservation.
  • the Regions are all high-brightness pixels, and the Sub-regions are low-brightness pixels.
  • the high-brightness pixels and the low-brightness pixels are too concentrated, so that the difference in brightness between the two regions is too obvious, resulting in poor visual effects.
  • the invention provides a wide viewing angle panel and a display device, which can solve the problem of high backlight power consumption existing in the prior art.
  • a technical solution adopted by the present invention is to provide a wide viewing angle panel including a plurality of mutually parallel scanning lines, a plurality of mutually parallel data lines, and a plurality of sub-pixels;

  • Each of the sub-pixels is connected to a first TFT, and a gate of the first TFT is connected to a scan line corresponding to the sub-pixel, and a source of the first TFT is connected to a data line corresponding to the sub-pixel.
  • the drain of the first TFT is connected to the pixel electrode of the sub-pixel, and each of the second sub-pixel is further connected to a second TFT for reducing the voltage of the pixel electrode of the second sub-pixel.

  • another technical solution adopted by the present invention is to provide a display device including the above wide viewing angle panel.
  • the present invention divides the pixel units in the wide viewing angle panel into two types, one is a first pixel unit with higher brightness, and the other is lower brightness. a second pixel unit, the area of the single first pixel unit and the area of the single second pixel unit are equal, and the first pixel unit and the second pixel unit are evenly distributed in the array, so that the two pixel units are uniformly mixed in the entire panel It not only improves the color shift of the wide viewing angle panel, improves the characteristics of the wide viewing angle, but also improves the transmittance of the wide viewing angle panel, thereby reducing the power consumption of the backlight, saving energy and environmental protection. In addition, since the two pixel units are uniformly mixed, the two pixel units having the difference in luminance are not excessively concentrated to affect the visual effect, and the number ratio of the two pixel units can be arbitrarily adjusted, so that the design is more flexible.

【技术领域】
本发明涉及液晶显示技术领域，特别是涉及一种广视角面板和显示装置。
【背景技术】
VA（Vertical Alignment）面板，是现在高端液晶应用较多的面板类型，属于广视角面板。
传统的VA模式液晶面板在广视角观看时，往往会出现色偏的问题。为改善广视角面板的色偏，现有的广视角面板将像素分为两个区，面板工作时，一个区（Main）的亮度较高，另外一个区（Sub）亮度较低，以通过该两个亮度不同的区来改善面板的广视角特性。
由于Sub区的面积较大（占像素开口区的60%左右），整个像素的穿透率会有较大的牺牲，增加了背光的功耗，不符合现在绿色环保节能的理念。此外，由于Main 区内均是高亮度像素，而Sub区内均是低亮度像素，高亮度像素和低亮度像素分别过于集中，使得两个区的亮度差异过于明显，导致视觉效果不佳。

其中，所述第二TFT的栅极与该第二子像素所在行对应的扫描线连接，所述第二TFT的源/漏电极的一端与该第二子像素的像素电极连接，另一端与该第二子像素对应的公共电极连接。
其中，所述第二TFT的栅极与该第二子像素所在行的下一行子像素对应的扫描线连接，所述第二TFT的源/漏电极的一端与该第二子像素的像素电极连接，另一端与一电容连接后与该第二子像素对应的公共电极连接。
其中，每行像素单元中，每个第一像素单元和每个第二像素单元间隔分布，且，每列像素单元中，每个第一像素单元和每个第二像素单元间隔分布。

【具体实施方式】
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
请参阅图1和图4，图1是本发明广视角面板第一实施例中像素单元的分布示意图。图4是本发明广视角面板中子像素与扫描线和数据项的连接结构第一实施例的示意图。
本发明的广视角面板为液晶显示面板，其包括显示区和非显示区（图未示），其中，显示区包括多条相互平行的扫描线100、多条相互平行的数据线200以及多个子像素300，其中，每个子像素300包括像素电极，该像素电极与一个公共电极对应，且在该像素电极与公共电极之间形成电容，从而产生电场使液晶发生偏转。
扫描线100和所述数据线200交叉分布，所述子像素300呈阵列分布，每行所述子像素300与每条所述扫描线100间隔设置，每列所述子像素300与每条所述数据线200间隔设置，每个所述子像素300均与所述扫描线100和所述数据线200电性连接。
本发明中，在每行所述子像素300中，每三个子像素300组成一个像素单元30，所述像素单元30呈阵列分布，其中，组成一个像素单元30的三个子像素300分别是红色子像素（R）、绿色子像素（G）和蓝色子像素（B）。
具体地，所述像素单元30包括第一像素单元31和第二像素单元32，所述第一像素单元31的亮度高于所述第二像素单元32的亮度，单个所述第一像素单元31的面积与单个所述第二像素单元32的面积相等，所述第一像素单元31均匀分布在所述陈列中，所述第二像素单元32均匀分布在所述阵列中。
区别于现有技术，本发明通过将广视角面板中的像素单元30分为两类，一种是亮度较高的第一像素单元31，一种是亮度较低的第二像素单元32，单个第一像素单元31面积和单个第二像素单元32的面积相等，且第一像素单元31和第二像素单元32在阵列中均匀地分布，使该两种像素单元30在整个面板中混合均匀，不仅能改善广视角面板发生色偏的问题，改善了广视角的特性，还能提高广视角面板的穿透率，从而降低了背光的功耗，节能环保。此外，由于两种像素单元30均匀混合，使得两种具有亮度差异的像素单元30不至于过于集中而影响视觉效果，且该两种像素单元30的数量比例可以任意调节，使得设计更加灵活。
具体地，第一像素单元31的数量与所述第二像素单元32的数量之比为0.1-100，例如：第一像素单元31的数量与所述第二像素单元32的数量之比为10-80，或者，第一像素单元31的数量与所述第二像素单元32的数量之比为40-70，或者，第一像素单元31的数量与所述第二像素单元32的数量之比为50-60等。
请继续参阅图1，本实施例中，每行像素单元30中，每个第一像素单元31和每个第二像素单元32间隔分布，并且，每列像素单元30中，每个第一像素单元31和每个第二像素单元32间隔分布。使得每个第一像素单元31的上、下、左、右四个方向都是一个第二像素单元32。而每个第二像素单元32的情况相同，其上、下、左、右四个方向都是一个第一像素单元31。
采用该种分布方式，第一像素单元31的数量与第二像素单元32的数量之比为1:1，使高亮度的第一像素单元31的面积提升到了50%，因此能有效提升广视角面板的穿透率，因而降低了背光的功耗。并且，由于第一像素单元31与第二像素单元32均匀混合，因此，能改善视觉效果，同时改善了广视角特性。
请参阅图2，图2是本发明广视角面板第二实施例中像素单元的分布示意图。
在每行像素单元30中，至少两个相邻的所述像素单元30组成一个行像素单元组，本实施例中，每行中两个相邻的像素单元30组成一个行像素单元组，当然，在其它实施例中，也可以是三个相邻的像素单元30，或者是四个、五个或者更多。所述行像素单元组包括第一行像素单元组310和第二行像素单元组320，所述第一行像素单元组310中的像素单元30均为第一像素单元31，所述第二行像素单元组320中的像素单元均为第二像素单元32，所述第一行像素单元组310和所述第二行像素单元组320在每行像素单元30中间隔分布。并且，在每列像素单元30中，至少两个相邻的所述像素单元30组成一个列像素单元组，本实施例中，每列中两个相邻的像素单元30组成一个列像素单元组，当然，在其它实施例中，也可以是三个相邻的像素单元30，或者是四个、五个或者更多。所述列像素单元组包括第一列像素单元组311和第二列像素单元组321，所述第一列像素单元组311中的像素单元均为第一像素单元31，所述第二列像素单元组321中的像素单元均为第二像素单元32，所述第一列像素单元组311和所述第二列像素单元组321在每列像素单元30中间隔分布。
采用本实施例的像素单元30的排列方式，同样可以使得第一像素单元31的数量与第二像素单元32的数量之比为1:1，是高亮度的第一像素单元的面积提升到了50%，因而能有效提升广视角面板的穿透率，因而降低了背光的功耗。并且，在每行中，第一行像素单元组310和第二行像素单元组320交错间隔排列，在每列中，第一列像素单元组311和第二列像素单元组321交错间隔排列，使得第一像素单元31和第二像素单元32在阵列中均匀分布，因而能改善面板的广视角特性和视觉效果。
请参阅图3，图3是本发明广视角面板第三实施例中像素单元的分布示意图。
本实施例中，在所述像素单元30形成的阵列中，围绕在每个所述第二像素单元32周围的八个所述像素单元均为第一像素单元31。
本实施例的第一像素单元31与第二像素单元32的数量之比为3:1，即，使得高亮度的第一像素单元31所占的面积提升到了75%，剩余的25%的面积为第二像素单元32，用于提升面板的广视角特性。因而，本实施例也有效地提升了面板的穿透率，降低了背光的功耗，且由于第一像素单元31和第二像素单元32并没有过度集中分布，因而具有较佳的视觉效果。
请参阅图4，图4是本发明广视角面板中子像素与扫描线和数据项的连接结构第一实施例的示意图。
本发明的广视角面板中，组成一个第一像素单元31的子像素300为第一子像素301，组成一个第二像素单元32的子像素300为第二子像素302。
本实施例中，第一子像素301和第二子像素302输入的是相同的灰阶信号，而第一子像素301的亮度则高于第二子像素302的亮度。
具体地，在同一行所述子像素300中的所述第一子像素301和所述第二子像素302均与该行子像素300对应的一条所述扫描线100连接。在同一列所述子像素300中的所述第一子像素301和所述第二子像素302均与该列子像素300对应的一条所述数据线200连接。即，每行子像素300均与同一条扫描线100连接，且该扫描线100是该行子像素300相邻的一条扫描线100，每列子像素300均与同一条数据线200连接，且该数据线200是该列子像素300相邻的数据线200。
上述仅是本发明的广视角面板中像素单元30的几种排列方式的实施例，本发明包括但不限于上述几种排列方式，能实现第一像素单元31和第二像素单元32均匀混合分布于阵列中即可。
像素单元输入相同的灰阶信号而亮度不同的实现主要通过以下方式：
本发明的每个子像素300均连接一个第一TFT41，所述第一TFT41的栅极与该子像素300对应的扫描线100连接，所述第一TFT41的源极与该子像素300对应的数据线200连接，所述第一TFT41的漏极连接一电容43后与该子像素300的像素电极连接。
每个所述第二子像素302还连接一个第二TFT42，用于降低所述第二子像素302的像素电极的电压。
请继续参阅图4，本实施例中，第二TFT42的栅极与该第二子像素302所在行对应的扫描线100连接，所述第二TFT42的源/漏电极的一端与该第二子像素的像素电极连接，另一端与该第二子像素对应的公共电极连接。
第二TFT42连接了公共电极之后，公共电极起分压作用，从而使该第二子像素302的像素电极与公共电极的电位更加接近，进而降低了所述第二子像素302的亮度。
请参阅图5，图5是本发明广视角面板中子像素与扫描线和数据项的连接结构第二实施例的示意图。
本实施例中，第二TFT42的栅极与该第二子像素302所在行的下一行子像素300对应的扫描线100’连接，所述第二TFT42的源/漏电极的一端与该第二子像素302的像素电极连接，另一端与一电容44连接后与该第二子像素对应的公共电极连接。
本实施例中，当面板工作时，一行子像素300对应的扫描线100开启，该行子像素300正常充电。充电完毕后，下一行子像素300对应的扫描线100’打开，将其上一行像素300的像素电极和增加的电容44连通，通过电容耦合作用使像素电极的电位更加接近公共电极，使该行的子像素300中的第二子像素302的亮度降低。
