具体实施方式
以下,参照附图对本发明的实施方式进行说明。另外,关于附图,对相同或同等的要素标注相同的附图标记,省略重复说明。
图1是用于说明本实施方式中的显示装置的背光源装置的概要的图。如图1所示,背光源装置100例如包含反射片101、导光板102、漫射片103、多个棱镜片104、光源(未图示)。
光源(未图示)沿导光板102的侧面配置。具体来说,例如,沿导光板102的4个侧面中的、1个侧面配置该光源。另外,关于光源的配置与导光板102之间的位置关系等将在后进一步说明。
光源如将后述那样,例如,由多个发光二极管(LED)构成,并列配置于基板(未图示)上。从光源入射的光在导光板102内反复全反射,从导光板102的上表面(光出射面)射出。反射片101重叠配置于导光板102,将从导光板102的背面射出的光向导光板102反射。
漫射片103例如是涂敷(coating)有使光漫射的树脂的薄膜,使从导光板102的表面射出的光漫射。棱镜片104分别是在表面上形成有棱镜或透镜的薄膜,使从漫射片103射出的光集中到与发光面垂直的方向。
图2是用于说明图1所示的背光源装置周边的显示装置的截面结构的概要的图。另外,在图2中为了简化说明,主要示意性地示出了背光源装置100周边的一部分中的主要结构,对于重叠配置于背光源装置100上的显示面板等省略图示。
如图2所示,在本实施方式中的显示装置中,在下框架201内,容纳有散热器204、背光源装置100。下框架201例如由沿显示装置的框体的形状形成的侧壁部202和位于与显示装置的显示面相反的一侧的底壁部203形成。如图2所示,侧壁部202例如在底壁部203的端部以包围底壁部203的方式形成。另外,下框架201例如由Al或Cu等金属形成。
另外,下框架201的底壁部203与显示装置框体的形状相应地,包含具有凹凸的凸部207和凹部208,该凹凸是相对于显示面的相反侧而言的凹凸。例如,在该凸部207,下框架201与显示装置的框体被螺纹固定。
具体来说,例如,如图2所示,下框架201例如从侧壁部202向朝向显示装置内部的方向,依次包含高度不同的凸部207、凹部208、凸部207、凹部208、凸部207。另外,例如,形成为这些凹部208的深度不同,另外,凸部207的宽度也不同。另外,上述凸部207和凹部208的形状仅是一个例子,例如,也可以根据显示装置框体的不同形状等而形成为不同的形状。
多个光源209沿导光板102的侧面配置。多个光源209例如由并列配置的多个发光二极管(LED)形成。另外,多个光源209配置于基板210上,该基板210沿下框架201的侧壁部202配置。
散热器204包含沿下框架201的侧壁部202形成的侧部205和沿下框架201的底壁部203形成的底部206。侧部205与基板210大致平行地配置。底部206沿下框架201延伸至规定的位置。
具体来说,例如,在图2所示的情况下,散热器204的底部206延伸至下框架201中的形成有凸部207且蓄积热的部分(空隙部211),以传导来自光源209的热。另外,散热器204的底部206从图2的上方来看,以与导光板102的一部分重合的方式延伸。换言之,底部206沿导光板102且与导光板102的一部分并行地配置。另外,在图2中,为了易于理解,示意性地将蓄积于空隙部211的热用圆表示。另外,下框架201与散热器204既可以以直接接触的方式形成,也可以以经由硅类油脂接触的方式形成。
接下来,对散热器204更具体的结构进行说明。图3是表示图2所示的散热器204周边的一部分的概要的立体图,图4是从图2的X方向观察的散热器周边的概要的图。另外,为了易于理解,在图3中,省略导光板102等,仅示出下框架201、光源209及配置有光源209的基板210和下框架201。另外,在图4中,省略光源209及配置有光源209的基板210等,仅示出下框架201、散热器204、反射片、导光板102。而且,在图3及图4中,为了易于理解,示出了规定数量的槽部301,实际上,例如,散热器204具有与光源209的数量相应数量的多个槽部301。
如图3所示,散热器204在从各光源209延伸的方向上沿下框架201的底壁部203具有多个槽部301。即,散热器204在从各光源209朝向导光板102的方向上在与底壁部203相反侧的面上具有各槽部301。从截面来看,例如,如图4所示,散热器204的底部206按规定间隔具有多个矩形形状的凹部的槽部301。
由此,如图3所示,关于来自各光源209的热,在例如作为液晶显示器等而使用那样将显示面板立起来使用的情况下,主要经由各槽部301而传导至下框架201的凸部207的空隙部211。然后,蓄积于该空隙部211的热经由下框架201向外部散热。另外,图3中此时的热的传导方向通过图2的箭头212表示。如箭头213所示,来自光源209的热也会有一部分沿显示面板所配置的方向传导,然而,在本实施方式中,主要设想的是如上述那样,将显示面板设为纵向(主要指使光源209相对于导光板102成为下方那样的朝向)而使用的情况,因此来自光源209的大量热经由槽部301向箭头212的方向传导。
各槽部301的宽度例如优选大于各光源209的宽度。另外,可以形成为槽部301的截面的宽度随着从光源209远离而宽度变宽。而且,在上述中对于按规定间隔形成有槽部301的情况进行了说明,但也可以例如与各光源209的配置相应地,按不同的间隔形成。
另外,如图2所示,从下框架201的底壁部203侧开始依次配置有反射片、导光板102、漫射片103、多个棱镜片104。另外,在图2的多个棱镜片104的上方配置有显示面板(未图示),该显示面板包括:配置有所谓的TFT等的TFT基板(未图示)、配置有彩色滤光片等的对置基板(未图示)、被封固于该两基板间的液晶,但因为以上结构是公知的,所以省略它们的详细说明。
根据上述的本实施方式,能够进一步降低光源209周边部的温度,由此能够提高光源209的可靠性。具体来说,例如,能够防止基于来自光源209的热所导致的光源209特性的变化,并且能够实现光源209的高寿命化。
本发明并不限于上述实施形式,能够进行多种变形。例如,能够用与上述实施方式中所示的结构实质上相同的结构、起到相同作用效果的结构或者能够达到相同目的的结构来替换。
例如,该槽部301的形状不限于上述,只要能够如上述那样提高光源209周边部的散热效果,也可以是不同的形状。具体来说,例如,如图5A所示,也可以使槽部301的截面形状为三角形。在这种情况下,也可以形成为随着从光源209远离,宽度变宽。而且,如图5B所示,也可以使槽部301的截面形状呈越朝向槽部301的中央而深度越深的形状。在这种情况下,也可以形成为随着从光源209远离,宽度变宽。另外,图5A及图5B与图4相同,表示从图2的X方向来看的截面的概要。
而且,例如,如图6所示,散热器204也可以构成为具有与上述槽部301交叉的一个或多个槽部302(交叉槽部302)。在这种情况下,例如,将显示面板纵向使用的情况中,也能够使热向横向传导,能够更加提高散热效果。另外,在这种情况下,如图7所示,将显示面板纵向使用的情况下,也可以形成向从散热器204的中央朝向外侧的方向具有角度的交叉槽部302。
另外,图6表示在散热器204上设置有交叉槽部302的情况下的散热器204的立体图的概要,图7表示设有散热器204的交叉槽部302的情况下的散热器204的俯视图的概要。另外,对于图6及图7,为了易于理解,只示出了规定数量的槽部301及交叉槽部302,但当然也可以是不同的数量。
另外,在图6及图7所示的情况下,交叉槽部302的截面形状也可以是其他形状,交叉槽部302的宽度也可以形成为与槽部301的宽度不同。另外,也可以形成为多个交叉槽部302的宽度彼此不同。
而且,在上述中,主要对使各光源209的每一个对应一个槽部301的情况进行了说明,但也可以形成为多个各光源209与一个槽部301对应。
在以上说明中,对于使用发光二极管作为光源209的情况进行了说明,但并不限定于此,也可以使用其他的所谓点光源。另外,本实施方式中的显示装置能够用作电脑用显示器、TV播放接收用显示器、公告显示用显示器等各种用于信息显示的显示装置。另外,也能够用作数码相机(digital still camera)、摄像机(video camera)、汽车导航系统、汽车音响(car audio)、游戏机、便携式信息终端等各种电子设备的显示装置。
