Description

像素结构及液晶显示面板 技术领域
本申请涉及显示技术领域，尤其涉及一种像素结构及液晶显示面板。
 背景技术
目前垂直配向型(Vertical Alignment，VA)模式的液晶显示器，使位于不同区域的液晶分子朝向不同方向倾倒，以达到广视角且提升穿透率的作用。而液晶显示器目前是市场上运用最为广泛的显示器，特别是广泛应用在液晶电视上。随着分辨率的逐步提升，画素的尺寸会越来越小，开口率也越来越小，大尺寸产品在观看的时候可观看的角度比较多，因此在大视角的时候会面临色偏的现象。现有研究发现，大视角一般致使色点坐标蓝移，即蓝色比预期更亮，且混色时蓝色的比例变高所致。模拟仿真计算中心十字主干部暗纹的左右色偏，发现在中间灰阶即低电压差时，左右侧视亮起明显，因而造成色彩冲刷淡化，不利于色偏表现；更具体的，是竖直方向的主干部，包含中心主干和侧向的主干。因此，由于蓝色像素结构中竖直方向的主干部在大视角漏光，导致色点坐标蓝移，混色时蓝色的比例变高，发生色偏现象。
综上所述，现有的像素结构及液晶显示面板，由于蓝色像素结构中竖直方向的主干部在大视角漏光，会加重色点坐标蓝移，使得混色时蓝色的比例变高，发生色偏恶化现象。

综上所述，虽然本申请已以优选实施例揭露如上，但上述优选实施例并非用以限制本申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
