Description

 有益效果
本发明实施例带来的有益效果为，本发明将驱动芯片旋转或不旋转180度的贴合在玻璃基板上（其中旋转后的驱动芯片的输入端和输出端与现有的驱动芯片的输入端和输出端位置相反）。将位于驱动芯片下方的柔性电路基板分成第一连接部和第二连接部，以分别连接到与驱动芯片水平齐平的两侧表面，有效降低下边框尺寸和显示面板厚度。然后，驱动芯片的上表面(或下表面或两侧表面)以第一金属层（但不限于第一金属层）连接到驱动芯片的输入端。将驱动芯片的输出信号（即输出端）通过第二金属层（但不限于第二金属层）输出给显示面板。因此下边框能够缩减柔性电路基板的高度空间和柔性电路基板到驱动芯片之间的走线距离，从而有效减小下边框的尺寸、降低显示模块整体厚度，并达到提高屏占比的效果。

 本发明的最佳实施方式
在具体实施方式中提及“实施例”意指结合实施例描述的特定特征、结构或特性可以包含在本发明的至少一个实施例中。在说明书中的不同位置出现的相同用语并非必然被限制为相同的实施方式，而应当理解为与其它实施例互为独立的或备选的实施方式。在本发明提供的实施例所公开的技术方案启示下，本领域的普通技术人员应理解本发明所描述的实施例可具有其他符合本发明构思的技术方案结合或变化。
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。本发明所提到的方向用语，例如[上]、[下 ]、[前]、 [后]、 [左]、 [右]、 [内]、 [外]、 [侧面 ]、[竖直]、[水平]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。在图中，结构相似的单元是用以相同标号表示。
请参照图1至图4所示，本发明提供一种窄边框显示模块，包括显示面板、驱动芯片及柔性电路基板。在此所指的窄边框显示模块可适用于智能手机、显示器件、笔记型电脑、电视等液晶显示面板（LCD）中。
如图1、图2及图4所示，显示面板1包括玻璃基板11和设置在所述玻璃基板11的TFT基板12。所述玻璃基板11具有突出所述TFT基板12一侧的下边框13。驱动芯片2贴合（bonding）在所述玻璃基板11的下边框13上。所述驱动芯片2包括相对应设置的输出端21和输入端22，以及邻接所述输出端21和所述输入端22的二侧表面23。
所述输入端22与所述TFT基板12的第一金属层121连接，所述输出端21与所述TFT基板12的第二金属层122连接。柔性电路基板3（FPC，flexible printed circuit）包括导电接点31和从所述导电接点31一侧延伸的第一连接部32和第二连接部33。所述第一连接部32和所述第二连接部33分别从所述二侧表面23连接所述输入端22，所述输出端122将输出信号通过所述第二金属层122传输至所述显示面板1。所述驱动芯片2还包括相对应设置的上表面24和下表面25。
请一并参照图3A所示，为本发明第一较佳具体实施例的布线横截面图，也就是驱动芯片与柔性电路基板之间布线的横截面图。当所述驱动芯片2旋转180度时，所述驱动芯片2的所述上表面24会贴合在所述玻璃基板11上。所述输入端22邻近所述TFT基板12设置，且所述输出端21远离所述TFT基板12设置。具体而言，所述第一连接部32和所述第二连接部33通过多个弯折后分别连接所述侧表面23的所述输入端22，有效缩小下边框13的尺寸，也能够达到降低显示面板1厚度的效果。然而在如图3B的实施例中，所述第一连接部32和所述第二连接部33也可分别从所述下表面25连接至所述驱动芯片2的所述输入端22，视需要而改变。
如图4所示的实施例中，所述第一金属层121较佳与所述第二金属层122异层设置，因此即使第一金属层121与第二金属层122彼此交叠设置，也不会造成短路。本实施例中的所述第一金属层121较佳为栅电极层，所述第二金属层122则为源漏电极层。然而在其他不同的实施例中，第一金属层121或第二金属层122也可以选自TFT层12中其他不同的金属层，视需要而改变。
请参照图5至图7B所示，为本发明第二较佳具体实施例的相关示图。本第二实施例与前述第一实施例的差异在于，当所述驱动芯片2未旋转时，所述驱动芯片2的所述下表面25会贴合在所述玻璃基板11上。所述输出端21邻近所述TFT基板12设置，且所述输入端21远离所述TFT基板12设置。
如图7A所示，所述第一连接部32和所述第二连接部33通过多个弯折后分别连接所述侧表面23的所述输入端22，有效缩小下边框13的尺寸，也能够达到降低显示面板1厚度的效果。然而在如图7B的实施例中，所述第一连接部32和所述第二连接部33也可分别从所述上表面24连接至所述驱动芯片2的所述输入端22，视需要而改变。
此外，所述柔性电路基板3还包括分别连接所述第一连接部32和所述第二连接部33的第一延伸部34和第二延伸部35。所述第一延伸部34和所述第一连接部32，以及所述第二连接部33和所述第二延伸部35分别形成U形，有效缩小柔性电路基板3与驱动芯片2之间走线距离。再者，所述柔性电路基板3的所述导电接点31突出于所述下边框13，且并未连接所述玻璃基板11，例如可翻折于下边框13的另一侧面，同样具有缩小下边框13尺寸的作用。
在如图1及图5所示的实施例中，所述显示面板1还包括显示区域14及围绕所述显示区域14的非显示区域15。所述下边框13位于所述非显示区域15。因此，本实施例的驱动芯片2例如为驱动内嵌式触控面板(in-cell touch panel) 的芯片(IC)，并直接压合在玻璃基板11上（COG ，chip on glass），制作快速、容易，且成本低。
本发明还提供一种显示装置，包括上述实施例所述的窄边框显示模块。在此所述的显示装置优选为液晶显示面板（LCD）。在一些次选的实施例中，所述显示装置也可是有机发光二极管（OLED）或其他适合的器件中。
本发明将驱动芯片2旋转或不旋转180度的贴合在玻璃基板1上，将位于驱动芯片2下方的柔性电路基板3分成第一连接部32和第二连接部33，以分别连接到与驱动芯片2水平齐平的两侧表面（或高于或低于驱动芯片），有效降低下边框13尺寸和显示面板1厚度。然后，驱动芯片2的上表面24(或下表面25或两侧表面23)以第一金属层121（但不限于第一金属层）连接到驱动芯片2的输入端22。将驱动芯片2的输出信号（即输出端21）通过第二金属层122（但不限于第二金属层）输出给显示面板1。
因此下边框13能够缩减柔性电路基板3的高度空间和柔性电路基板3到驱动芯片2之间的走线距离，从而有效减小下边框13的尺寸、降低显示模块整体厚度，达到提高屏占比的效果，并扩大有效显示区域14（active area，AA)的面积，进而达到更高阶的视觉体验和产品设计美感。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
