本发明所提供的液晶模组及液晶显示装置, 具有如下有益效果: 由于液 晶模组中设有可使 COF基带朝向某一特定方向进行弯折的定位件, 定位件 的至少一端侧由前框紧固在前框和胶框之间。 定位件可以应用在超窄边框的 模组设计中, 避免装配中在 COF基带的周围直接装配前框, 降低造成 COF 基带上翻剥落或刺伤的几率; 提升产品的良率, 使生产成本进一步降低。 附图说明 图 1是本发明实施例液晶模组中组装有定位件的结构示意图。
图 2是现有技术中液晶模组组装前框使 COF基带卷曲的结构示意图。 具体实施方式
下面参考附图对本发明的优选实施例进行描述。
参见图 1 , 为本发明实施例液晶模组中组装有定位件的结构示意图。 本 实施例中的液晶模組包括液晶玻璃 1、 胶框、 前框 3以及 COF基带 4。
液晶玻璃 1的上下两表面分别由胶框进行抵压,胶框分别包括如图 1所 示位于液晶玻璃 1上表面的顶胶框 21和位于液晶玻璃下表面的底胶框 22。 两胶框 21、 22在液晶模组的内部分别装配定位后, 可通过前框 3对其进行 抵压, 两胶框 21、 22将液晶玻璃 1紧固。
COF基带 4的一端部 4a接连在液晶玻璃 1的一端侧, 两者保持高密度 接合。 在对 COF基带 4和液晶玻璃 1进行接合的过程中, COF基带 4处于 平整未弯折的状态。
也就是说, 刚装配 COF基带 4在液晶玻璃 1的端侧上时, COF基带 4 的两端侧 4a、 4b大致保持在同一平面上。
本实施例中, 通过定位件 5可使上述处于平整未折弯的 COF基带 4朝 向如图 1所示的下方进行折弯,并使其能够容纳在定位件 5具有的容置腔 51 中, 将 COF基带 4折弯是使 COF基带 4的形态能够满足超窄边框模组组装 的需要。
定位件 5的作用是避免在 COF基带 4的周围直接装配前框 3,降低造成 COF基带 4上翻剥落的几率。 其具体结构及实施方式下述详细说明。
定位件 5是由塑胶材料或金属材料制成的截面呈 L型的板件。通常, 定 位件 5使用与前框 3相同的制成材料, 以保证模组能够控制在一定的重量范 围内, 且能够快速安装。 定位件 5具有相互垂直的横板 52和竖板 53 , 横板 52的一端部与液晶面板 1顶部的顶胶框 21实现预固定,与其相连的竖板 53 保持在距离底胶框 22侧体不远处的位置上。
横板 52、 竖板 53、 顶胶框 21以及大致呈 Z字形的底胶框 22相互围挡 形成了 L型的容置腔 51, 而被抵压在两胶框 21、 22之间的波晶玻璃 1的端 部及接合在其上的 COF基带 4也刚好能够容纳在该容置腔 51中。
进一步的, 定位件 51具有折弯 COF基带 4的功用。
实施时, 定位件 5作用在平整接合在液晶玻璃 3—端侧的 COF基带 4 上,使 COF基带 4的端侧 4b能够朝向容置腔 51内部的方向进行弯折。 COF 基带 4弯折容纳在容置腔 51中时, COF基带 4折弯的端侧 4b相距定位件 5 的竖板 53, 以及底胶框 22的侧体始终具有一定的距离。 其作用是: 在端侧 4b完成朝向预定方向弯折的操作下, 而使 COF基带 4不被定位件 5以及紧 接着要组装的前框 3触碰到。
前框 3的形状与定位件 5的形状相同, 都是截面呈 L型的板件, 前框 3 通过其内壁挤压预固定的定位件 5 , 将其緊固。
具体装配时, 定位件 5完成上述 COF基带朝向某一特定方向弯折的操 作后,便可将定位件 5横板 22的一端固定在液晶玻璃 1上方顶胶框 21的表 面上。 这样, 横板 52、 竖板 53、 顶胶框 21 以及底胶框 22之间的相对位置 固定后, 组装前框 3, 前框 3通过其内侧壁的挤压能够将定位件 5紧固。
优选的实施方式中, 定位件 5的宽度小于或等于 COF基带 4的宽度。 这样设置的作用是: 组装过程中更容易目测到 COF基带 4的弯折朝向; 在提升装配前框 3效率的基 上, 使定位件 5的尺寸尽可能的小, 有利于降 低材料成本。
例如: 定位件 5的宽度与 COF基带 4的宽度保持大致相等的基础上, 按照上述实施方法能够目测到 COF基带 4的折弯朝向, 即如图所示的向下 方折弯, 同时, 也能够目测到 COF基带的两端 4a、 4b分別与定位件 5的横 板 52和竖板 53相平行。
优选的实施方式中, 定位件 5的厚度在 0.3mm以内。 其作用是进一步 减小增加定位件 5后对组装前框 3的影响。 实验数据表明, 定位件的厚度在 0.3mm时, 本结构液晶模组的前框 3依然能够抵压在上述胶框结构上, 保证 了装配的可靠性; 同时, 使用较薄的定位件 5 , 有利于成本控制。
本发明还公开了一种具有上述液晶模组的液晶显示装置, 该液晶显示装 置的实施方式包含上述液晶模组的任一种实施方式, 此处不再赘述。
实施本发明的液晶模組及液晶显示装置,由于液晶模组中设有可使 COF 基带朝向某一特定方向进行弯折的定位件,定位件的至少一端侧由前框紧固 在前框和胶框之间。 定位件可以应用在超窄边框的模组设计中, 避免装配中 在 COF基带的周围直接装配前框, 争低造成 COF基带上翻剥落或刺伤的几 率; 提升产品的良率, 使生产成本进一步降低。
以上所揭露的仅为本发明较佳实施例而已, 当然不能以此来限定本发明 之权利范围, 因此等同变化, 仍属本发明所涵盖的范围。
