下面参考附图对本发明的优选实施例进行描述。
结合参见图 1-图 6, 为本发明液晶模组的实施例一。
如图 1所示， 为本发明实施例液晶模组的结构示意图。 本实施例中的液 晶模组包括光源 1 , 散热装置 2、 导光装置 3、 胶框 4、 液晶玻璃 5、 背板 6 以及前框 7, 其中：
光源 1采用 LED或 LED灯条的结构形式， 封装在设有折弯的散热装置 2的内侧， 散热装置 2在实施时可以是设为折弯的铝挤；
散热装置 2与背板 6固定连接；
胶框 5分别紧固在散热装置 2和包含有导光装置 3的光学部材上， 光学 部材在实施中除包含导光装置 3外还包含有扩散板， 棱镜， 扩散板等部材。
液晶玻璃 5由胶框 4和前框 7紧固。
进一步的， 导光装置 3在本实施例中可设为导光板， 其固定在光源 1的 发光侧，并与光源 1保持一定的距离，导光板使用亚克力等材料经注塑成型。
本实施例中， 藕光装置 9装设在光源 1和导光装置 3之间， 其是截面呈 工字状的条杆结构。藕光装置 9可以使用与导光板相同的材料和制作工艺制 成， 当其与光源 1进行装配安装时， 由于藕光装置 9具有与导光板相同的材 料特性， 不但不会影响光源的发光， 而且可在同一产线上进行生产， 降低生 产成本。
本实施例中， 藕光装置 9朝向光源 1的侧面 91抵压在光源 1上。
进一步的， 请结合参见图 2、 图 3所示， 分别为本发明实施例藕光装置 的立体结构和截面结构示意图。 其中， 藕光装置 9朝向 LED的侧面 91上开 设第一凹槽 92,第一凹槽 92的宽度和深度尺寸设置与 LED光条的宽度和高 度尺寸大体相同， LED光条能够容纳在第一凹槽 92中。 此外， 藕光装置 9 的另一侧面 92则朝向导光板进行安装，该侧面 92可以保持与导光板相接触， 也可保持与导光板具有一定的距离。
第一凹槽 92具有三个壁面， 分别为 92a、 92b和 92c。 实施时， 可以保 持至少有一个壁面 92a、 92b或 92c与 LED光条相接触，其余壁面与 LED光 条保持一定的距离。 如此设置的作用是， 满足藕光装置 9与 LED进行装配 的前提下， 防止藕光装置 9因受热膨胀对模组的藕光效率造成影响。 当然， 在藕光装置 9膨胀量可控的前提下， 也可保持三个壁面 92a、 92b和 92c与 LED光条的三个侧面分别相接触，藕光装置 9能够起到的控制藕光距离的作 用不变。
此外， 藕光装置 9与三个壁面 92a、 92b或 92c间的装配可采用焊接或 粘贴的方式。
本实施例中， 藕光装置 9远离光源 1的侧面 93抵压在导光装置 3上。 进一步的， 藕光装置 9远离 LED的侧面 93上开设第二凹槽 94, 第二凹 槽 94与上述第一凹槽 92开设的位置对称， 其能够起到对导光板端部进行容 置、 且为导光板预留膨胀空间的作用。
具体地， 第二凹槽 94具有三个壁面， 分别为 94a、 94b和 94c。 实施时， 可以保持至少有一个壁面 94a、 94b或 94c与导光板的端部 31相接触， 其余 壁面与导光板的该端部 31保持一定的距离。
综上， 液晶模组通过设置上述藕光装置 9, 可以保持导光板和光源间的 藕光距离为设计值， 例如， 当导光板或 LED光源的尺寸存在差异、 或导光 板受热膨胀导致藕光距离变化时， 由于藕光装置 9的存在， 其可以防止光源 或导光板之间的藕光距离过大或急剧变小情况的发生。
如图 4所示， 为本发明藕光装置第二实施例的截面示意图， 本实施例与 上述实施例的不同之处在于： 藕光装置 9仅在朝向 LED的侧面 91上开设凹 槽 92, 而远离 LED的侧面 93为一平面， 装配时， 该侧面 93可以与导光板 相接触。
如图 5所示，为本发明藕光装置第三实施例的截面示意图，本实施例中， 藕光装置的截面呈 L形， 其设有折弯的一侧 91与 LED相接触， 设为平面的 一侧 93与导光板相接触。 如图 6所示，为本发明藕光装置第四实施例的截面示意图，本实施例中， 藕光装置的截面呈 T 字形， 其两侧分别设有一折弯， 该设有折弯的两侧面 91 , 93分别与 LED和导光板相接触。
如图 7所示， 为本发明液晶模组第五实施例中 LED灯条装配藕光装置 的结构示意图， 本实施例中， LED灯条设置为三段， 相邻两段 LED灯条间 具有卡位 11 , 藕光装置 9设置为可装设在上述卡位 11中的相连的两块体结 构。
结合参见图 8, 藕光装置 9的整体呈 U状， 其两端部具有的两块体 95、 96的截面分别呈矩状。 由于块体 95、 96的厚度尺寸大于 LED的高度尺寸， 当两块体 95、 96装设在卡位 11中后， 藕光装置 9的顶面 97高于 LED的发 光面， 该顶面 97与导光板的端部相接触。
由于该顶面 97高于 LED的发光面， 当导光板受热膨胀时， 膨胀量会被 推到与 LED发光侧相对的对光侧的一侧， 进而可使 LED和导光板之间的藕 光距离不受影响。
本实施例中的藕光装置 9的至少一个壁面与光源相接触， 其也可以采用 与导光板相同的材料和制作工艺制成， 其与 LED的装配可采用焊接或粘贴 的方式。
实施本发明的液晶模组及采用该液晶模组的液晶显示装置， 具有如下有 益效果： 由于在所述光源和所述导光装置之间装设藕光装置， 其可以将导光 板和光源间的藕光距离保持在一设计值， 可以避免因导光板或 LED产品的 差异性及其受热膨胀导致藕光距离发生变化的情况； 进一步提高液晶模组的 藕光效率， 提升产品的品质。
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。
