Description

一种液晶屏-栅极COF结构组件及液晶显示装置 技术领域
本发明涉及液晶显示领域，具体是一种液晶屏-栅极COF结构组件及液晶显示装置。
背景技术
随着液晶显示技术的快速发展，提供更加轻薄、更窄边框的液晶显示装置已成为行业发展趋势。由于显示器厚度以及外观的限制，若要实现对其进行超薄、超窄边框设计，则需要重新对其零部件定位结构进行优化设计，使其结构更加紧凑。
如图1所示为现有的液晶屏的结构示意图，其中在液晶屏1的两侧设有栅极COF结构2(CHIP ON FILM，常称覆晶薄膜，将驱动IC固定于柔性线路板上晶粒软膜构装技术)，用于处理图像扫描信号。由于栅极COF结构是将IC固定于柔性线路板上，极易受到破坏，因此需要妥善收纳，以防外力的冲击使其破损。
如图2所示为一种现有液晶显示装置的局部示意图，该图中示出了一种收纳栅极COF结构的方式。栅极COF结构2的上端与液晶屏1相连，且从液晶屏1向下翻折，设置在背光模组3的胶框34和前框5之间的空隙中。采用这种收纳方式时，为了对栅极COF结构起到保护收纳作用，背光模组的厚度不可能设置成小于栅极COF结构的长度，即背光模组的厚度受限于该栅极COF结构，进而使得整个液晶显示装置的厚度受限，难以设计成超薄液晶显示装置。
如图3所示也是一种现有液晶显示装置的局部示意图，该图中示出了另一种现有的用于收纳栅极COF结构的方式。在该种显示器的设计中，栅极COF结构2的左端与液晶屏1相连接，并从连接处向右沿水平方向平摊地设置在背光模组3的胶框34与液晶屏1之间的空隙中。采用这种收纳方式时，虽然背光模组的厚度不再受限于栅极COF结构，使得显示器可以设计成超薄产品，但是由于栅极COF结构的平摊，导致整个液晶显示装置的边框长度受限于栅极COF结构的长度，难以实现超窄边框显示器的设计。
由此可见，现有的液晶显示装置中，受限于栅极COF结构的收纳设计，无 法同时实现液晶显示装置的超薄和超窄边框设计。因此实有必要对上述问题进行改进，以优化液晶显示装置的结构，使其更加紧凑，减少内部零部件占用的空间，从而同时实现液晶显示装置的超薄和超窄边框设计。

其中，在本发明中，所述栅极COF结构的开孔通过冲切成型工艺制成，栅极COF结构在设计线路时，避开这些开孔位置，从而使得所述开孔不会影响栅 极COF结构的功能。
与现有技术相比，本发明的有益效果如下：
首先，本发明对栅极COF结构进行优化，不同于现有技术中将栅极COF结构平摊收纳或者竖向收纳的方式，本发明中将栅极COF结构进行弯折设置，使其与液晶屏之间的结构设计紧凑，不占用过多空间，极大程度上减少了因设置栅极COF结构对液晶显示装置的厚度以及边框长度的限制，从而使得液晶显示装置可以同时实现超薄和超窄边框的设计。此外，由于在栅极COF结构的弯折处会存在应力，这种应力有可能会对覆晶薄膜或其上的线路造成一定的影响，因此本发明通过在栅极COF结构弯折处开设镂空结构，以减小不良应力。由于栅极COF结构在设计线路时可避开这些镂空结构的位置，因此栅极COF结构的功能并不会受到影响。

另外，在本发明中，将朝向液晶屏的前表面(即显示图像的表面)一侧的方向称为前方，将朝向液晶屏的后表面(即液晶屏背面)一侧的方向称为后方。
实施例一
本发明提供一种液晶显示装置，包括液晶屏、设置在所述液晶屏侧边上的栅极COF结构、设置于所述液晶屏后方的背光模组以及设置在所述液晶屏和所述背光模组外侧的前框；其中，所述栅极COF结构一端连接于所述液晶屏的侧边，且从所述液晶屏的侧边朝向所述液晶屏的背面弯折，使所述栅极COF结构的另一端连接于所述液晶屏的背面，所述背光模组位于所述栅极COF结构的后方，所述前框位于所述栅极COF结构弯折处的外侧，所述液晶屏、所述背光模组和所述前框共同围合形成用于容置所述栅极COF结构的容置空间。
实施例二
结合图4、图5、图6所示，本实施例提供一种液晶显示装置，包括液晶屏1，设置在液晶屏1左右侧边11上的栅极COF结构2，设置于液晶屏1后方的背光模组3，设置在背光模组3后方的背板4以及设置在液晶屏1、背光模组3和背板4左右两侧的前框5，液晶屏1、背光模组3和背板4组合在一起，左右两 侧通过前框5进行组合固定。
可以理解的是，该液晶显示装置还包括设置在液晶屏、背光模组以及背板顶部的上盖，将液晶屏、背光模组以及背板组合在一起，顶部通过上盖进行组合固定，该上盖采用常规技术中的上盖即可，在此不再赘述。
结合图4和图6所示，背光模组3包括依次设置在液晶屏1后方的膜片31、导光板32和反射片33，在膜片31、导光板32和反射片33的四周设有胶框34，胶框34将膜片31、导光板32和反射片33固定在其内部。如图6所示为本实施例液晶显示装置的局部剖面示意图，其中胶框34作为背光模组的外框设置在膜片31、导光板32及反射片33的左侧。前框5设置在胶框34的外侧(即图6中胶框的左侧)，且前框5的上侧边缘朝向液晶屏1方向弯折延伸形成第一弯折部。背板4设置在胶框34和反射片33的底部，且该背板4的左侧边缘朝向前框5方向弯折延伸形成第二弯折部，该第二弯折部设置在前框5与胶框34的空隙中。液晶屏1、前框5的第一弯折部、胶框34以及背板4的第二弯折部共同形成了一容置空间。
可以理解的是，该背光模组还包括设置在导光板一侧的光源(图未示)，该光源例如设置在导光板与胶框之间，或者胶框内部开设有容纳槽结构，在其容纳槽内设置该光源。
结合图6、图7所示，栅极COF结构2一端(图7中栅极COF结构顶面的右端)连接于液晶屏1的侧边11(图7中液晶屏的左侧边)，且从液晶屏1的该侧边朝向液晶屏1的背面弯折180°，再通过双面胶6将栅极COF结构2的另一端(图7中栅极COF结构滴面的右端)与液晶屏1的背面贴合固定，从而使栅极COF结构2固定在液晶屏1的侧边附近。背光模组的胶框34位于栅极COF结构2的下方，前框5位于栅极COF结构2弯折处的外侧(图7中的左侧)，使栅极 COF结构2容置在前述容置空间中。本实施例通过将栅极COF结构弯折180°后固定设置在液晶屏侧边附近，使得液晶屏侧边的栅极COF结构更加紧凑，更有利于液晶显示装置的超薄、超窄边框设计。
如图6、图7所示，在该栅极COF结构2上固定有芯片21，芯片21设在该栅极COF结构2弯折形成的空间内部，该芯片21设置在液晶屏1的下侧，即芯片21与液晶屏1的背面相对设置，此时用于贴合栅极COF结构与液晶屏的双面胶6的厚度大于芯片21的厚度，以保证芯片不会直接接触到液晶屏背面，从而避免因芯片与液晶屏背面接触碰撞对栅极COF结构造成破坏。可以理解的是，在本发明中，芯片位置还可以有其他设置，如图8所示，芯片21与液晶屏1的侧边位于同一侧，此时双面胶6的厚度不受限于芯片21的厚度。
此外，考虑到栅极COF结构的弯折处会存在应力，此应力有可能会对覆晶薄膜或其上的线路造成一定的影响，因此本实施例可对栅极COF结构做进一步优化设计，如图9所示，在栅极COF结构2的弯折处设至若干开孔22作为镂空结构，以减小不良应力。上述开孔是通过冲切成型工艺制成的，栅极COF结构在设计线路时，避开这些开孔位置，从而使得所述开孔不会影响栅极COF结构的功能。
本发明还提供一种液晶屏-栅极COF结构组件，该组件即为上述液晶显示装置中的液晶屏和设置在液晶屏侧边上的栅极COF结构，在此不再赘述。
以上所述为本发明的具体实施方式，其目的是为了清楚说明本发明而作的举例，并非是对本发明的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明权利要求的保护范围之内。
