Description

液晶层的形成方法及液晶显示面板、液晶滴注装置 【技术领域】
本发明涉及液晶显示技术领域，具体而言涉及一种阵列基板、液晶显示面板及液晶显示装置。
【背景技术】
液晶显示(Liquid Crystal Display，LCD)面板是由两块基板贴合而成，在其成盒(Cell)制程中，需要将液晶滴在其中一块基板的胶框内。当前业界的普遍做法是在基板上滴下多个重量一致的液晶单滴，并使其均匀分布在基板上，后续通过VAC Chamber(Vacuum Chamber，真空室)真空贴合两块基板，使得液晶扩散在胶框限定的液晶盒内。
被滴下的液晶单滴的排列形式即为液晶图形(Pattern)，不同的液晶图形以及单滴液晶的液晶量会影响液晶的扩散效果，如果扩散不均匀，则容易产生seal(密封)穿刺、edge gap(边缘间隙)以及bubble(气泡)等问题，影响产品品质。例如，参阅图1，如果滴注于液晶盒边缘的单滴液晶11与胶框12之间的距离太近，则单滴液晶11扩散后会产生seal穿刺，此时位于第二排的单滴液晶11与胶框12之间的距离太远，扩散后会产生edge gap，从而在液晶显示面板内产生bubble。又例如，参阅图2，如果滴注于液晶盒边缘的单滴液晶21与胶框22之间的距离太远，则单滴液晶21扩散后会产生edge gap，从而在液晶显示面板内产生bubble；而相邻单滴液晶21之间的距离较近，则会导致扩散不均匀，影响产品品质。
【发明内容】
有鉴于此，本发明实施例提供一种液晶层的形成方法及液晶显示面板、液晶滴注装置，能够提高液晶扩散的均匀度，避免产生seal穿刺、edge gap、bubble等问题，改善产品品质。

其中，所述第一滴注包括：根据液晶密度和液晶盒的厚度、长度、宽度得到理论液晶量；根据理论液晶量以及在中间区域内所要形成的液晶图形，得到滴注于第一胶框的中间区域的单滴液晶量；将具有单滴液晶量的单滴液晶滴注于中间区域，并得到单滴液晶在扩散后与第一胶框之间的实际距离。
其中，所述第二滴注包括：将具有单滴液晶量的单滴液晶滴注于第二胶框的边缘区域，并根据扩散结果调整单滴液晶的液晶量，直至扩散后的单滴液晶的直径等于所述实际距离；获取调整后的单滴液晶的液晶量以及在边缘区域内所要形成的液晶图形，并据此进行滴注。
其中，第一滴注的滴注图形包括矩阵图形，第二滴注的滴注图形包括矩形。

其中，第一滴注图形包括矩阵图形，第二滴注图形包括矩形。
本发明一实施例的液晶滴注装置，包括：第一滴注单元，用于在第一基板一侧的第一胶框的中间区域进行第一滴注；第二滴注单元，用于在第二基板一侧的第二胶框的边缘区域进行第二滴注，其中第二滴注和第一滴注所滴注的单滴液晶量不同；贴合单元，用于将第一胶框和第二胶框对应贴合，以在第一基板和第二基板之间形成密封的液晶盒，贴合后的边缘区域对应环绕于中间区域的周围，第一滴注和第二滴注所滴注的液晶在液晶盒内扩散形成液晶层。
其中，第一滴注单元用于根据液晶密度和所述液晶盒的厚度、长度、宽度得到理论液晶量，并根据理论液晶量以及在中间区域内所要形成的液 晶图形得到滴注于中间区域的单滴液晶量，进一步将具有单滴液晶量的单滴液晶滴注于中间区域，从而得到单滴液晶在扩散后与第一胶框之间的实际距离。
其中，第二滴注单元用于将具有单滴液晶量的单滴液晶滴注于边缘区域，并根据扩散结果调整单滴液晶的液晶量，直至扩散后的单滴液晶的直径等于实际距离，从而获取调整后的单滴液晶的液晶量以及在边缘区域内所要形成的液晶图形，并据此进行滴注。
其中，第一滴注的滴注图形包括矩阵图形，第二滴注的滴注图形包括矩形。
本发明实施例在两块基板侧进行滴注，两块基板侧进行滴注的单滴液晶的液晶量不同，即能够根据其中一块基板侧的液晶扩散结果优化调整另一块基板侧的滴注，从而能够提高液晶扩散的均匀度，避免产生seal穿刺、edge gap、bubble等问题，改善产品品质。

【具体实施方式】
本发明实施例的目的是在液晶显示面板的两块基板侧分别进行滴注，两块基板侧进行滴注的单滴液晶的液晶量不同，据此提高液晶在液晶盒内压合扩散的均匀度，避免产生seal穿刺、edge gap、bubble等问题，改善液晶显示面板的产品品质。
下面结合本发明实施例中的附图，对本发明所提供的各个示例性的实施例的技术方案进行清楚、完整地描述。在不冲突的情况下，下述的实施例及实施例中的技术特征可以相互组合。
请参阅图3，为本发明一实施例的液晶滴注方法。该方法包括：
S31：在第一基板一侧的第一胶框的中间区域进行第一滴注。
S32：在第二基板一侧的第二胶框的边缘区域进行第二滴注，其中第二滴注和第一滴注所滴注的单滴液晶量不同。
S33：将第一胶框和第二胶框对应贴合，以在第一基板和第二基板之间形成密封的液晶盒，贴合后的边缘区域对应环绕于中间区域的周围，第一滴注和第二滴注所滴注的液晶在液晶盒内扩散形成液晶层。
结合图4所示的液晶显示面板40，其包括相对间隔设置的彩膜基板(Color Filter Substrate，又称CF基板或彩色滤光片基板)41和阵列基板(Thin Film Transistor Substrate，又称TFT基板、薄膜晶体管基板或Array基板)42以及填充于两基板之间的液晶43。基于此，本实施例所述的第一基板为彩膜基板41和阵列基板42中的一个，而第二基板为彩膜基板41和阵列基板42中的另一个。下文以第一基板为彩膜基板41、第二基板为阵列基板42为例进行描述。
进一步参阅图5，第一胶框411位于彩膜基板41一侧，第二胶框421位于阵列基板42一侧，两侧胶框通过贴合可形成密封的用于容置液晶43的液晶盒。在液晶盒形成后，第一胶框411的中间区域Z1和第二胶框421的边缘区域Z2组成液晶盒所包括的区域。
上述方法即是在第一胶框411和第二胶框421内分别进行第一滴注和第二滴注，并且控制两次滴注的单滴液晶的液晶量不同。据此，本实施能够根据液晶43在第一胶框411内的扩散结果对第二框胶421内的液晶滴注进行调整，或者根据液晶43在第二框胶421内的扩散结果对第一胶框411内的液晶滴注进行调整，即本实施能够根据液晶43在其中一块基板侧的扩散结果优化调整另一块基板侧的滴注，使得两基板贴合后液晶43在液晶盒内的扩散尽可能均匀，从而避免产生seal穿刺、edge gap、bubble等问题，改善液晶显示面板40的产品品质。
下文以根据液晶43在第一胶框411内的扩散结果对第二框胶421内的液晶滴注进行调整为例介绍本实施例的滴注原理及过程。
所述第一滴注的原理及过程如下：
当液晶显示面板40的型号确定之后，液晶盒的尺寸就已经确定。根据 液晶盒的厚度、长度、宽度可得到液晶盒的容积，继而根据关系式m＝ρ*h*l*d即可得到液晶显示面板40所需的理论液晶量，其中m为理论液晶量，h、l、d分别为液晶盒的厚度、长度、宽度。
根据理论液晶量以及在第一胶框411的中间区域Z1内所要形成的液晶图形，得到滴注于该中间区域内Z1的单滴液晶量。举例而言：以图5所示为例，中间区域Z1内所要形成的液晶图形为矩阵图形，可通过多次尝试得到一个合适的滴数能够等分该中间区域Z1的长和宽，并且确保相邻两滴液晶43之间的距离位于预定阈值内，其中该预定阈值用于确保相邻两滴液晶43在液晶盒内扩散后相互抵接，该预定阈值可根据经验或者多次试验记录得到。然后根据中间区域Z1所占液晶盒的比例得到中间区域Z1所需的理论液晶量。最结合根据中间区域Z1内的液晶滴数，即可得到滴注于该中间区域内Z1的单滴液晶量。
将具有单滴液晶量的单滴液晶43滴注于中间区域Z1，得到单滴液晶43在扩散后与第一胶框411之间的实际距离。
其中，滴注于中间区域Z1内的液晶43在扩散后所占据的实际区域可能大于该中间区域Z1，也可能小于该中间区域Z1，从而导致液晶盒的剩余区域与第二胶框421的边缘区域Z2不相同，因此需要优化调整滴注于该边缘区域Z2内的单滴液晶43的液晶量。
所述第二滴注的原理及过程如下：
首先，将具有单滴液晶量的单滴液晶43滴注于第二胶框421的边缘区域Z2，观察单滴液晶43的扩散结果。然后，根据扩散结果调整单滴液晶43的液晶量，直至扩散后的单滴液晶43的直径等于前述实际距离。最后，获取调整后的单滴液晶43的液晶量以及在边缘区域Z2内所要形成的液晶图形，并据此对边缘区域Z2的剩余区域进行滴注。
继续参阅图5，以第一滴注的单滴液晶量对边缘区域Z2进行滴注，具体可以在邻近于边缘区域Z2的顶点滴注第一滴单滴液晶43。然后，根据其扩散结果调整单滴液晶43的液晶量，直至扩散后的第一单滴液晶43的直径等于前述实际距离，即扩散后的第一单滴液晶43抵接于第二胶框421的两个相交的边、以及滴注于中间区域Z1内的液晶43在扩散后所占据的实际区域的边缘。根据调整后的单滴液晶43的液晶量以及在第二胶框421的边 缘区域Z2内所要形成的液晶图形，即矩形，得到滴注于该边缘区域Z2内的滴数，从而完成滴注。
应该理解到，根据液晶显示面板40的形状，上述中间区域Z1和边缘区域Z2内的液晶图形还可以为其他形状，例如，液晶显示面板40为椭圆形时，中间区域Z1和边缘区域Z2可以均为椭圆形。
请参阅图6，为本发明一实施例的液晶滴注装置。结合图4和图6所示，该液晶滴注装置60包括第一滴注单元61、第二滴注单元62以及贴合单元63。第一滴注单元61用于在第一基板41一侧的第一胶框411的中间区域Z1进行第一滴注。第二滴注单元62用于在第二基板42一侧的第二胶框421的边缘区域Z2进行第二滴注，其中第二滴注和第一滴注所滴注的单滴液晶量不同。贴合单元62用于将第一胶框411和第二胶框421对应贴合，以在第一基板41和第二基板42之间形成密封的液晶盒，贴合后的边缘区域Z2对应环绕于中间区域Z1的周围，第一滴注和第二滴注所滴注的液晶43在液晶盒内扩散形成液晶层。
其中，第一滴注单元61和第二滴注单元62可以为业界普遍采用的液晶滴嘴，两者的滴注原理及过程可参阅前述。
由于该液晶滴注装置60也能够根据液晶43在第一胶框411内的扩散结果对第二框胶421内的液晶滴注进行调整，或者根据液晶43在第二框胶421内的扩散结果对第一胶框411内的液晶滴注进行调整，即能够根据液晶43在其中一块基板侧的扩散结果优化调整另一块基板侧的滴注，使得两基板贴合后液晶43在液晶盒内的扩散尽可能均匀，因此液晶滴注装置60也避免制得的液晶显示面板产生seal穿刺、edge gap、bubble等问题，改善产品品质。
需要说明，以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，例如各实施例之间技术特征的相互结合，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
