Description

窄边框液晶模块及其胶框 技术领域
本发明是涉及一种液晶模块，特别是有关于一种窄边框液晶模块及其胶框。

液晶显示装置为目前最广为使用的显示装置产品，液晶显示装置系藉由液晶面板的液晶层以控制各像素位置的光线透射率，使得液晶显示装置能够正确地显示影像。由于液晶显示装置中的液晶面板不能自发光，因此需要背光模块以提供液晶面板所需的光源，使液晶显示装置达到显示的效果。背光模块结构有直下式(direct type)以及侧入式(edge-lit type)。所谓的直下式背光模块是指光源，如冷阴极灯管(CCFL)或发光二极管(LED)，在液晶面板背部列阵，发出的光线通过导光板(light guide plate)、扩散板(diffuser board)、棱镜片(prism sheet)等光学膜片，呈现均一的面光源；所谓的侧入式背光模块是指发光二极管(LED)灯条(light bar)置于液晶面板侧边，光入射到导光板，通过导光板把线光源转为均匀面光源。
液晶显示装置主要包括液晶面板、背光模块及框架三项基本构件，其中，框架系包覆于液晶面板及背光模块外缘，用以承载内部零组件并提供保护作用。目前，在液晶显示设备技术的发展上，窄边框设计的液晶显示设备能够在有限的空间内提供更大的观看视角，是液晶显示设备外观的一大革新。然而，如何在可靠地固定液晶面板及背光模组的前提下，让液晶模块外边框尺寸缩小，甚至做到无边框的外观，是窄边框液晶显示设备在技术上的主要问题之一。

 本发明的最佳实施方式
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。再者，本发明所提到的方向用语，例如上、下、顶、底、前、后、左、右、内、外、侧面、周围、中央、水平、横向、垂直、纵向、轴向、径向、最上层或最下层等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。
请参照图1所示，其揭示本发明第一实施例的一种窄边框液晶模块10，所述窄边框液晶模块10包含：一液晶面板11及一背光模块12，其中所述液晶面板11可为塑料或玻璃基板。请参照图2所示，在本发明第一实施例中，所述背光模块12进一步包含：至少一光学薄膜13、一背板14及一胶框15，所述背板14例如为以金属冲压成型的后框，其用以承载所述光学薄膜13，而所述胶框15则例如是以塑料射出成型的边框，其围绕于所述背板14周围。在本发明实施例中，所述光学薄膜13可包含光学膜片、导光板、扩散板或其组合，但不在此限。
请再参照图2所示，在本发明实施例中，所述胶框15的相对两侧分别具有至少一固定结构16，例如一、二、三个固定结构16或以上，但不在此限，且所述固定结构16例如可位于所述胶框15的相对两长侧上，或亦可位于所述胶框15的相对两短侧上，但不在此限。在本发明实施例中，所述固定结构16包含：一弹性卡勾17、至少一肩部18及一卡掣空间19，所述弹性卡勾17是用以弹性卡合所述液晶面板11的前缘；所述肩部18为凸设在所述胶框15的内侧，以支撑所述液晶面板11的后缘；而所述卡掣空间19形成在所述弹性卡勾17及肩部18之间，以卡掣固定所述液晶面板11的侧缘。如图2所示，所述固定结构16的弹性卡勾17结构优选是与所述胶框15以塑料射出成型而一体成型制成的。
接着，请参照图3所示，在本发明第一实施例的窄边框液晶模块10中，每一所述固定结构16具有一所述弹性卡勾17及至少二肩部18，每一所述固定结构16的所述至少二肩部18可设置在所述弹性卡勾17的两侧，且位在所述胶框15相对两侧的固定结构16的弹性卡勾17各具有一圆弧的外导引面171。
请参照图4所示，在本发明第一实施例中，所述窄边框液晶模块10的组装方式是将所述液晶面板11水平地向下压入所述背光模块12的胶框15中，如此所述液晶面板11相对两侧的后缘可以同时施一向下压力予所述胶框15相对两侧的弹性卡勾17的外导引面171，以克服所述弹性卡勾17的弹性偏压，使得所述弹性卡勾17暂时水平向外变形。待所述液晶面板11整个进入所述胶框15中，所述液晶面板11相对两侧的侧缘即卡掣固定于所述卡掣空间19内。此时，所述肩部18支撑所述液晶面板11的后缘，而所述弹性卡勾17则水平向内复位而弹性卡合所述液晶面板11的前缘。
请参照图5所示，在本发明第二实施例的窄边框液晶模块10构造相似于本发明第一实施例，并大致沿用相同组件名称及图号，但第二实施例的差异在于：所述弹性卡勾17可区分为至少一第一弹性卡勾20及第二弹性卡勾21，其中所述第一弹性卡勾20及第二性卡勾21分别位于所述胶框15的相对两侧。在本发明第二实施例中，所述第一弹性卡勾20位于所述胶框15一侧的固定结构16上，并具有一圆弧的内导引面201；而所述第二弹性卡勾21则位于所述胶框15另一相对侧的固定结构16上，且具有一圆弧的外导引面211。
因此，如图6所示，在本发明第二实施例中，所述窄边框液晶模块10的组装方式是先将所述液晶面板11的一侧的侧缘先沿着所述内导引面201倾斜卡入所述第一弹性卡勾20的卡掣空间19内，再将所述液晶面板11的另一侧的侧缘向下压入所述第二弹性卡勾21内，此时所述液晶面板11此侧的后缘施一向下压力予此侧的第二弹性卡勾21的外导引面211，以克服所述第二弹性卡勾21的弹性偏压，使得所述第二弹性卡勾21暂时水平向外变形。待所述液晶面板11整个进入所述胶框15中，所述液晶面板11相对两侧的侧缘即皆卡掣固定于所述卡掣空间19内。此时，第二侧的所述肩部18支撑所述液晶面板11同侧的后缘，而所述第二弹性卡勾21则水平向内复位而弹性卡合所述液晶面板11的前缘。
依上述说明，本发明的优点在于：由于所述固定结构16的所述弹性卡勾17、20、21具有圆弧导引面171、201、211，因此能够以压入或倾斜插入所述液晶面板11的方式，与所述背光模块12进行组装。由此可知，本发明的窄边框液晶模块10不但可以简单并快速地完成组装，更能够可靠地固定液晶面板及背光模组，因而进一步提高窄边框液晶模块的生产效率。
值得一提的是，本发明的另一优点在于：一种窄边框液晶模块10的胶框15的设计。由于本发明的窄边框液晶模块10的弹性卡勾17、20、21构造简单且可以与所述胶框15一体成型，因而可以窄化液晶模块的边框，缩小液晶模块外边框尺寸，以使窄边框设计的液晶显示设备能够在有限的空间内提供更大的观看视角。此外，本发明窄边框液晶模块10的胶框15的设计可节省前框部件，减少窄边框液晶模块的部件数目，进一步降低窄边框液晶模块的生产成本。
本发明已由上述相关实施例加以描述，然而上述实施例仅为实施本发明的范例。必需指出的是，已公开的实施例并未限制本发明的范围。相反地，包含于权利要求书的精神及范围的修改及均等设置均包括于本发明的范围内。
