Description

液晶显示面板 技术领域
本申请涉及显示技术领域，尤其涉及一种液晶显示面板。
 背景技术
液晶显示器的主体结构为液晶面板，在液晶面板的制造过程中，盒厚和抗压能力的设计是液晶显示器的关键技术之一，其直接影响液晶显示器的品质。当液晶显示面板处于低温状态时，液晶收缩，这时就会出现真空气泡；当液晶显示面板处于高温状态时，液晶受热膨胀，这时就会容易导致面板内部液晶发生整体向下流动，产生重力不均匀现象。工艺过程中，在不发生低温气泡和重力不均现象的允许液晶量控制范围，称为液晶填充范围（LC Margin）。目前为了解决上述问题，通常利用隔垫物之间的段差来确保均一的盒厚来满足液晶填充范围。现有技术通常采用两个厚度相同的支撑柱，在主支撑柱的下方增加一金属垫片，此金属垫片采用长条形，支撑柱与金属垫片形成十字交叉，使得主支撑柱与辅支撑柱间具有段差。但是由于金属垫片的宽度较窄，主支撑柱材质较软，金属垫片会陷入主支撑柱中，采用此种设计，支撑柱段差无法达到设计值，造成液晶填充范围较窄，使液晶显示面板有低温气泡风险。
综上所述，现有的液晶显示面板，在主支撑柱下增加一垫片形成段差时，由于金属垫片的宽度过窄而主支撑柱材质较软，导致金属垫片会陷入主支撑柱中，使支撑柱段差无法达到设计值，进一步使液晶填充范围较窄，更进一步使液晶显示面板有低温气泡风险。
