Description

液晶显示器
技术领域
本发明涉及一种液晶显示器,且更具体地,涉及一种通过将灯连接到外部电源而使加工(workability)更容易并能降低组装成本的液晶显示器。
背景技术
本申请要求2009年8月28日提交的韩国专利申请No.10-2009-0080229的优先权,此处以引证的方式并入其全部内容,就像在此进行了完整阐述一样。
通常,液晶显示设备由于其轻重量、薄外形和低功耗的特性,应用范围越来越宽。LCD设备现在用于办公自动化设备、音频/视频设备等。
液晶显示设备包括以矩阵形式设置的多个控制开关,且根据施加于控制开关的信号来控制光的透射量,由此产生期望的图像。由于液晶显示设备不是自发光显示设备,因此其需要独立的光源,如背光单元。
根据光源的位置,背光单元通常分为直下型和侧光型。侧光型背光单元具有沿着液晶显示设备的一侧的光源,并通过导光板和多个光学片将来自光源的光源照射到液晶面板。直下型背光单元具有直接设置在液晶面板下面的多个光源,并通过散射板和多个光学片将来自光源的光照射到液晶面板。近来,由于与侧光型背光相比,直下型背光单元具有提高的亮度、更一致的光均匀性和更好的色纯度,因此直下型背光单元被更频繁地使用。
主要使用冷阴极荧光灯(下文中,称作“CCFL”)和外部电极荧光灯(下文中,称作“EEFL”)作为背光单元的光源。由于EEFL的电极暴露在其外部,所以与电极是插入到玻璃管中的CCFL相比而言,EEFL更易于并联驱动。
图1示出了在直下型LCD中,将灯和外部电源连接的常规方法。灯用EEFL来实现,且灯的电极1弹性地压靠在导电夹2上,并电连接到固定在公共板3上的公共电极4。并且,灯的电极1由侧支架5支撑和固定。公共板3是由塑料制成的模制品,且由底盖9支撑。灯线8将公共电极4和逆变器(未示出)相互连接,以将由逆变器产生的灯驱动功率传输给公共电极4。
图1中所示的连接方法在安全方面具有优势,但是由于在将灯线8连接到公共电极4时需要螺钉紧固件6和点焊7,因此具有低的组装性。此外,此方法与近来提出的IPB(集成电源板)模型不兼容。IPB模型具有一逆变器,该逆变器在常规技术中被单独提供,并且该逆变器集成于系统的电源板中,以使LCD更轻薄且更便于组装。因此,如果是由模块制造商来完成没有逆变器的液晶模块的组装,则设备制造商将集成电源板组装到液晶模块以向灯提供灯驱动功率。在这种IPB模型中,通过插针连接器(pin connector)的连接将集成电源板与灯电连接,以使组装简单化。然而,图1中所示的连接方法不允许连接器连接,由此降低了模型兼容性。
发明内容
本文的一个方面是提供一种液晶显示器,其通过将灯连接到外部电源而使加工更容易且能够降低组装成本。
本文的另一个方面是提供一种液晶显示器,其通过与IPB模型兼容而使部件产品化(commoditization)并提高了可组装性。
为了实现上述方面,根据本发明的示例性实施方式,提供了一种液晶显示器,该液晶显示器包括:液晶面板;多个灯,其用来产生待照射到液晶面板上的光;公共板,其包括与灯的电极接触的公共电极;底盖,其容纳灯和公共板;以及插座连接器,其位于公共板的一侧并与外部电源和公共电极电连接,其中插座连接器的电接触部分通过贯穿公共板和底盖的通孔而暴露在外。
插座连接器包括与公共板一体形成的壳体和由壳体支撑的端子。
壳体是由绝缘材料制成的模制品,并且壳体具有内部空间,用来从中穿过端子的一部分并在其中插入与外部电源连接的插头连接器。
端子包括:第一接触部分,其与插头连接器电接触;第二接触部分,其与公共电极接触;以及主体部分,其沿着壳体的表面弯曲并连接第一接触部分和第二接触部分。
第一接触部分沿着内部空间插入到通孔中,第二接触部分通过螺钉紧固件连接到公共电极。
第一接触部分由至少两个插针构成。
灯的每一个电极弹性地压靠在导电夹上,且导电夹与公共电极一体形成。
各个灯是外部电极荧光灯。

具体实施方式
下文中,将参照图2至8描述本文的实施方式。
图2示出了根据本发明的示例性实施方式的液晶显示器。
参照图2,根据本发明的示例性实施方式的液晶显示器包括壳盖102、液晶面板106、背光单元和集成电源板145。
壳盖102具有一个矩形框架,且围绕液晶面板106和背光单元的边缘。
液晶面板106包括上基板103和下基板105。液晶层(未示出)形成在上基板103和下基板105之间。液晶面板106具有间隔体(未示出),用来保持上基板103和下基板105之间的恒定间隙。
上基板103具有滤色器、公共电极和黑底(未示出)。根据电场驱动方法,公共电极可形成在下基板105上。信号线,例如数据线和选通线(未示出),形成在液晶面板106的下基板105上。薄膜晶体管(下文中,称作“TFT”)形成在数据线和选通线的交叉处。响应于来自选通线的扫描信号(即,选通脉冲),TFT对数据信号进行切换,以将其从数据线传送到液晶单元。像素电极形成在数据线和选通线之间的像素区域上。
液晶面板106的一侧分别具有数据焊盘区域和栅焊盘区域。多个带载封装(下文中,称作“TCP”)104和108以相同间隔附接到数据焊盘区域和栅焊盘区域。这些TCP 104和108将源PCB 128和数据焊盘进行电连接。TCP 104和108包括数据TCP 108和栅TCP 104,其中该数据TCP108具有安装在其上的数据驱动集成电路110,用来向数据线提供视频信号,该栅TCP 104具有安装在其上的选通驱动集成电路112,用来向选通线提供选通信号。在GIP(面板内栅极,Gate In Panel)方法中,可以省略栅TCP 104。
背光单元包括:并排设置的多个灯120,用来向液晶面板106照射光;引导支架121,用来将灯120插入其中并覆盖灯120的边缘;底盖114,其设置在灯120的后表面,用来容纳灯120;散射板116,其设置在灯120的前表面,用来散射灯120所产生的光;以及多个光学片118,用来朝向液晶面板106使散射板116上聚集和入射的光的行进路径垂直提升。
灯120可以包括EEFL,其具有暴露在外的电极。灯120的电极通过在公共板123上相互导电而共同连接。插座连接器形成在公共板123的一侧。插座连接器耦合到插头连接器130,并向公共板123的公共电极施加来自集成电源板145的灯驱动功率。下面将参照图3至7详细描述公共板123和插座连接器。
底盖114容纳灯120和公共板123。反射片(未示出)可粘接到底盖114的与灯120相对的内表面。
散射板116散射从灯120入射的光,由此使照射到液晶面板106上的光的分布密度一致。散射板116上堆叠的多个光学片118将从散射板116入射的光转化为与液晶面板106垂直,由此提高光的效率。
侧支架121具有多个凹槽,用来将灯120的末端插入其中,并且侧支架121从底盖114的两侧支撑灯120。
集成电源板145包括逆变器,以产生灯驱动功率。在液晶模块组装完成之后,由设备制造商将集成电源板145固定在底盖114的后表面上。为了实现与灯的电连接,电缆132和插头连接器130被连接到集成电源板145。
图3示出了其上形成有插座连接器的公共板123的一个示例。
参照图3,灯120的电极120a弹性地压靠在导电夹125上,并电连接到固定在公共板123上的公共电极124。导电夹125与公共电极124一体形成。因此,在本发明中,与近来提出的平衡PCB型不同,可以省略用于将导电夹125附接于平衡PCB(印刷电路板)的单独的SMT(表面安装技术)工序,由此大大降低了成本且更易于解决SMT焊接缺陷所导致的安全问题。公共电极124能够通过螺钉紧固件154或环扣紧固件(hook fastening)156而被固定在公共板123上。
插座连接器127形成在公共板123的一侧,并与插头连接器130耦合,该插头连接器130插入穿过底盖114和公共板123,以从插头连接器130向公共电极124传输灯驱动功率。
为此,插座连接器127具有与公共板123一体形成的壳体126和由壳体126支撑的端子128。壳体126是由绝缘材料(如塑料)制成的模制品,并通过在制造公共板123时与公共板123一体形成而成型。壳体126具有内部空间126a,用来从中穿过端子128的一部分并插入插头连接器130以实现电接触。内部空间126a通过穿透公共板123和底盖114的通孔(未示出)而暴露在外部。如图4和5中所示,端子128包括:第一接触部分128a,其与插头连接器130电接触;第二接触部分128b,其与公共电极124接触;以及主体部分128c,其沿着壳体126的表面弯曲并连接第一接触部分128a和第二接触部分128b。第一接触部分128a沿着壳体126的内部空间126a插入到通孔中。第一接触部分128a由两个插针构成,用来与插头连接器130连接。第二接触部分128b通过对螺钉152进行紧固而连接到公共电极。
图6示出了其上形成有插座连接器的公共板123的另一个示例。
参照图6,灯120的电极120a弹性地压靠在导电夹125上,并电连接到固定在公共板123上的公共电极124。导电夹125与公共电极124一体形成。因此,在本发明中,与近来提出的平衡PCB型不同,可以省略用于将导电夹125附接于平衡PCB(印刷电路板)的单独的SMT(表面安装技术),由此大大降低了成本且更易于解决SMT焊接缺陷所导致的安全问题。公共电极124能够通过螺钉紧固件154或环扣紧固件156而被固定在公共板123上。
插座连接器127’形成在公共板123的一侧,并与插头连接器130耦合,该插头连接器130插入穿过底盖114和公共板123,以从插头连接器130向公共电极124传输灯驱动功率。
为此,插座连接器127’具有壳体126’,该壳体126’与公共板123和由壳体126’支撑的端子128’一体形成。壳体126’是由绝缘材料(如塑料)制成的模制品,并通过在制造公共板123时与公共板123一体形成而成型。壳体126’具有内部空间126a’,用于从中穿过端子128’的一部分并插入插头连接器130以实现电接触。内部空间126a’通过穿透公共板123和底盖114的通孔(未示出)而暴露在外部。如图4和5中所示,端子128’包括第一接触部分128a’,其与插头连接器130电接触;第二接触部分128b’,其与公共电极124接触;以及主体部分128c’,其沿着壳体126’的表面弯曲并连接第一接触部分128a’和第二接触部分128b’。第一接触部分128a’沿着壳体126’的内部空间126a’插入到通孔中。第一接触部分128a’包括三个插针,用来与插头连接器130连接。第二接触部分128b’通过对螺钉152进行紧固而连接到公共电极124。
图8示出了底盖114的后表面上的插头连接器130的连接状态。
参照图8,插头连接器130连接到通过通孔140而露出的插座连接器的端子(第一接触部分),由此能够将通过电缆132施加给集成电源板145的灯驱动功率施加到公共板123的公共电极上。
如上所述,由于在连接灯和外部电源时的简单结构,根据本发明的液晶显示器能够使加工更容易,且可以在很大程度上降低组装成本,并且,由于不需要SMT焊接工序,所以不会发生由于焊接缺陷而导致的质量问题,由此确保安全。
此外,由于在连接灯和外部电源时允许连接器连接,所以根据本发明的液晶显示器与IPB模型兼容,因此大大有助于部件的产品化和组装性的提高。
根据上述描述,对于本领域技术人员显而易见的是,可以进行各种修改和变型而不偏离本发明的技术构思。因此,本发明的技术范围应该由所附权利要求来限定,而不是由说明书的具体描述来限定。
