在日本专利申请公开No.平11-2813中,公开了与具有直背光部件的液晶显示器件相关的一种技术,其中,对线性光源(未示出)分别提供了半圆柱形的反射器,线性光源与反射器彼此作为一个整体,做得可以沿着侧面滑动,且相对于框是可拆卸的。 In Japanese Patent Application Publication No. Hei 11-2813 discloses a technique related to a liquid crystal display device backlight having a linear member, wherein the linear light source (not shown) are provided a semi-cylindrical reflector, the linear light source and the reflector to each other as a whole, made slidable along the side, with respect to the frame is detachable. 反射器用作图1所示的背反光镜28以及侧反射器29。 Reflector is shown plotted on the back side of the mirror 28 and the reflector 29. 依据其中所述的结构,背光部件的亮度变均匀了,且线性光源的更换容易。 Wherein according to the configuration, luminance of the backlight of the member becomes uniform, and easily replace the linear light source.

此外,在日本专利申请公开No.平11-146305中,公开了一种与液晶显示器件相关的技术,其中提供了一个支承液晶板的框、一个漫射器以及一个背光部件,所述框是由两个纵向框、两个横向框以及四个角部件构成的。 Further, in Japanese Patent Application Publication No. Hei 11-146305 discloses a liquid crystal display device of the related art, which provides a support frame of the liquid crystal panel, a diffuser, and a backlight assembly, the box is two vertical frame, and the four corners of the two cross frame members thereof. 依据其中所描述的结构,即便液晶显示器件尺寸很大,也可以通过抑制用于制造框的模制机械尺寸的增加以及其中所用的模具的尺寸的增加,来抑制框的成本。 Depending on the structure described therein, even if the liquid crystal display device large in size, can be suppressed by increasing the size of the mechanical molding for manufacturing box as well as increasing the size of the mold used therein, to suppress the cost of the frame.

但是,上述传统的液晶显示器件具有以下问题。 However, the above conventional liquid crystal display device has the following problems. 首先,与使用阴极射线管的显示器相比,液晶显示器件的成本高。 First, as compared with a display using a cathode ray tube, the high cost of the liquid crystal display device. 因此,对于液晶显示器件来说,降低成本是当务之急。 Thus, the liquid crystal display device, the cost is a priority. 另外,目前还需要减小液晶显示器件的大小,并增大显示区的尺寸。 Further, there is a need to reduce the size of the liquid crystal display device, and increase the size of the display area. 为满足这一需求,就得使围绕图象显示部分的、并不用于显示图象的图象框区域尽可能地窄。 To meet this demand, have to strike around the image display portion, an image frame region is not for displaying images as narrow as possible.

在前述日本专利公开No.2000-75273中,公开了一种液晶显示器件,它在降低图象框的成本以及弄窄图象框时受到限制,这是因为其中使用的器件数目非常大,包括金属底座26以及定位部件27。 In the aforementioned Japanese Patent Publication No.2000-75273, there is disclosed a liquid crystal display device, it is limited in time and cost reduction of the image frame to narrow picture frame, this is because the use of very large number of devices, including the metal base 26 and a positioning member 27. 同样,在前述日本专利申请公开No.平11-2813中,公开了一种液晶显示器件,它也存在一个问题:由于分别为多个线性光源提供了多个反射器,因此成本增加。 Also, in the aforementioned Japanese Patent Application Publication No. Hei 11-2813 discloses a liquid crystal display device, it is also a problem: Since a plurality of reflectors are provided a plurality of linear light sources, thereby increasing the cost. 此外,在前述日本专利公开No.平11-146305中,公开了一种液晶显示器件,它有可能抑制用于制造框的模制机械的尺寸的增加,以及其中所用的模具尺寸的增加,但由于构成框的器件数目大,因而也在减小成本上受到了限制。 Further, in the aforementioned Japanese Patent Publication No. Hei 11-146305 discloses a liquid crystal display device, it is possible to suppress an increase in size of the molding machine for the manufacture of the frame, and increasing the size of the mold used therein, but due to the large number of devices constituting the frame, thereby also reducing the cost is limited.

发明概述本发明的一个目的是提供与传统液晶显示器件相比,成本低、图象框区域较窄的液晶显示器件。 SUMMARY OF THE INVENTION An object of the present invention is to provide a liquid crystal display device as compared with conventional, low cost, narrow picture frame area of ​​the liquid crystal display device.

依据本发明的液晶显示器件包括若干光源、背反光镜、漫射器、液晶板以及一个框;所述背反光镜位于液晶显示器件背面,以便反射来自光源的光;所述漫射器与背反光镜相对,同时光源位于它们之间,用于透射和漫射从光源发射出的光;液晶板选择性地透射已经穿过漫射器的光,从而形成图象;与漫射器支承部分以及液晶板支承部分设置成整体的框,漫射器支承部分用于支承漫射器,而液晶板支承部分用于支承液晶板。 The liquid crystal display device according to the present invention comprises a plurality of light source, back reflector, diffusers, liquid crystal panel and a frame; the back of the mirror on the back of the liquid crystal display device, so that the reflected light from the source; and the diffuser back opposing mirror, while the light source is positioned therebetween, and for transmitting the light emitted from the light source diffusion; a liquid crystal panel selectively transmitting light that has passed through the diffuser, thereby forming an image; and supporting the diffuser portion and a liquid crystal panel supporting frame portion disposed integrally diffuser support portion for supporting the diffuser plate and the liquid crystal supporting portion for supporting the liquid crystal panel.

在本发明中,由于所提供的框既设有支承漫射器边缘部分的漫射器支承部分,又设有支承液晶板边缘部分的液晶板支承部分,因此,有可能省略作为传统液晶显示器件的必备部件的定位件、金属底座以及树脂框。 In the present invention, since the frame is provided with supporting both edge portions of the diffuser support portion of the diffuser, it is provided with a liquid crystal panel and the liquid crystal panel supporting portion for supporting an edge portion, and therefore, it is possible to omit a conventional liquid crystal display device essential element of the positioning member, the metal base and the resin frame. 所以,有可能使所用的器件数目少于传统液晶显示器件中的器件数目,由此,可以减少组装液晶显示器件的工序,因此,有可能降低液晶显示器件的成本。 Therefore, it is possible to make the number of devices is less than the number of devices used in a conventional liquid crystal display device, whereby a liquid crystal display device can be reduced in the assembly process, therefore, it is possible to reduce the cost of the liquid crystal display device. 另外,由于省略了金属底座,所以有可能使图象框变窄。 Further, since the metal base is omitted, it is possible to make the image block is narrowed.

最好是,将光源分别安装在每个背反光镜上,且其两端可以通过由弹性材料构成的安装部件拆卸。 Preferably, the light sources are mounted on each of the back mirror, and two ends of mounting member can be made of an elastic material removal. 在这种情况下,由于光源是安装在背反光镜上的,因此,当需要更换液晶显示器件内的光源时,可通过拆卸背反光镜,而一次更换所有的光源。 In this case, since the light source is mounted on the back of the mirror, and therefore, when it is necessary to replace a light source in the liquid crystal display device can be detached by back reflector, a light source and a replacement of all. 因此,提高了光源更换工作的效率。 Thus, improving the efficiency of replacement of the light source. 除此之外,有可能减缓从外部施加到光源上的振动以及冲击,从而,防止了光源的损坏。 In addition, it is possible to slow down the externally applied vibrations and impacts on the light source, thereby preventing damage to the light source.

另一方面,在前述日本专利申请公开No.2000-75273中公开了一种液晶显示器件,当需要更换灯30(线性光源)时,如图1所示,必须从液晶显示器件中拆除包括树脂框31、背反光镜28、侧反射器29、灯30、漫射器25、金属底座26以及定位件27的全部结构,之后,再从全部结构中拆除金属底座26以及漫射器25,再后,拆除灯30。 On the other hand, a liquid crystal display device is disclosed in the aforementioned Japanese Patent Application Publication No.2000-75273, when the need to replace the lamp 30 (linear light source) shown in Figure 1, must be removed from the liquid crystal display device includes a resin block 31, the back mirror 28, 29, lamp 30, 25, 26 and all of the base structure of the metal member 27 positioned side reflectors diffuser, after removal of the metal base 26 and then a diffuser 25 from the entire structure, and then after removal of the lamp 30. 这样,在更换灯时,需要化费大量的时间和劳动力。 Thus, when replacing the lamp, you need a lot of time and labor costs.

在前述日本专利申请公开No.平11-2813中,公开了一种便于灯的更换的技术。 In the aforementioned Japanese Patent Application Publication No. Hei 11-2813 discloses a technique of replacing the lamp to facilitate. 但是,其中所公开的技术只适用于一只一只地更换灯。 However, the techniques disclosed therein is only suitable for a replacement of a lamp. 但是,随着灯的工作时间的推移,灯的亮度会降低,因此,如果在液晶显示器件中仅仅更换一只灯,仅仅这只新灯变得比其它灯亮,从而导致屏幕亮度变得不均匀。 However, with the passage of operating time of the lamp, the lamp brightness decreases, and therefore, if only to replace the lamp in a liquid crystal display device, only the new light only becomes brighter than other light, thereby causing the screen brightness becomes uneven . 因此,通常,只要有一支灯损坏,就要一起更换所有的灯。 Thus, in general, have a long light damage, it is necessary to replace all the lights together. 在前述日本专利申请公开No.平11-2813中公开了一种液晶显示,当一次需要更换所有的灯时,需要一只一只地取出并更换灯,这样灯的更换工作变得非常麻烦。 In the aforementioned Japanese Patent Application Publication No. Hei 11-2813 discloses a liquid crystal display, when the need to replace all of the lamps, one needs to be removed and a replacement lamp, so the lamp replacement work becomes cumbersome. 另一方面,在本发明中,可以通过拆除背反光镜,而一次对所有光源(灯)都进行更换,这样,可以有效地更换光源。 On the other hand, in the present invention, by removing the mirror back, and once for all light sources (lamps) are replaced, so that, effectively replace the light source.

框可以具有侧反射器,用于将从所述光源发射出的光朝向所述液晶板反射。 Block may have a side reflector for the light emitted from the light reflected toward the liquid crystal panel. 可以沿着框的内表面,即沿着液晶显示器件的内表面,提供所述侧反射器。 May extend along the inner surface of the frame, i.e. along the inner surface of the liquid crystal display device, there is provided the side reflector. 利用这一结构,有可能省略作为传统液晶显示器件内的必备部件的这种独立的侧反射器的使用。 With this structure, it is possible to omit the use of such a separate side reflector essential component in the conventional liquid crystal display device.

可以通过连接至少两个分开的框,而将框组装成框状。 By connecting at least two can be separated from the frame, and the frame is assembled in a frame shape. 可以在四个拐角处,将框分开,通过连接四个基本上是线性的、分开的框,可以将其组装为一个框。 It can be at the four corners, the frame separated by connecting four substantially linear, separate blocks, which can be assembled into a box. 在这种情况下,将漫射器和背反光镜安装到框内变得更容易了。 In this case, the diffuser and the back mirror is mounted to frame becomes easier. 除此之外,还可以减小用于制造框的模具的大小,因此有可能减少液晶显示器件的成本。 In addition, to reduce the size of the mold can also be used to manufacture the frame, it is possible to reduce the cost of the liquid crystal display device.

最好是,也可以通过模制树脂来形成分开的框,或是通过涂敷树脂的金属来构成分开的框。 Preferably, the resin may be formed by molding a separate frame, or a frame constituted by a separate metal-coated resin. 因此,不仅使分开的框的模制变得容易,而且还有可能省略使用于传统的液晶显示器件内的、用于保护由玻璃制成的液晶板的垫片。 Thus, not only the separate frame molding is facilitated, but also possible to omit the use in the conventional liquid crystal display device, a liquid crystal panel for protecting the gasket made of glass. 结果,有可能进一步降低所使用的元件的数目,并较大程度地抑制了成本。 As a result, it is possible to further reduce the number of components used, and the cost is suppressed to a large extent.

此外,背反光镜可以包括一个金属板以及涂敷在该金属板上的一种反射材料,从而构成一个反射表面。 Moreover, a back reflector may comprise a metal plate and a specular material coated on the metal plate, thereby forming a reflecting surface. 结果,有可能使漫射并反射光,因而可以提供一种背反光镜,它很薄且强度很高。 As a result, there is likely to diffuse and reflect light, it is possible to provide a back reflector, it is thin and high strength. 这里如前所述的反射材料可以使用,例如表现出反射作用的颜色的树脂,举例来说,一种白色树脂。 Here reflective material as described above may be used, for example, exhibit a color reflection of a resin, for example, a white resin.

这样,依据本发明,有可能提供一种液晶显示器件,与传统的液晶显示器件相比,它成本低、且图象框较窄。 Thus, according to the present invention, it is possible to provide a liquid crystal display device, compared with the conventional liquid crystal display device, it is low cost, and the image frame is narrow.

图9是透视图,它显示了背反光镜8、灯安装部件9以及灯10的结构。 9 is a perspective view showing a configuration of a back reflector 8, 9 and the lamp mounting member 10 of the lamp. 如该图所示,若干凹口部分8b以相等的间距形成于背反光镜8的边缘部分。 As shown in FIG, several notch portion 8b are formed at equal intervals on the back edge portion 8 of the mirror. 每一个灯安装部件9都具有凹陷9a以及U形截面部件9b。 Each lamp mounting member 9 having a recess 9a and a U-shaped section member 9b. U形截面部件内部设有一个凸起部分(未示出),用于安装到相应的凹口部分8b内。 U-shaped section is provided with a raised portion interior member (not shown), for mounting into the respective recess portions 8b. 通过将这一凸起装入相关的凹口部分8b,有可能对每个灯安装部件9进行有效定位。 By loading the associated projection recess portion 8b, it is possible for each lamp mounting member 9 effectively positioned.

将作为冷阴极放电管的灯10的端部装配进灯安装部件9的凹陷9a内。 The cold cathode discharge lamp into the end portion of the lamp assembly 10 is mounted within the recess 9a of the member 9. 通过将U形截面部件9b安装到背反光镜上形成的凹口部分8b的位置上,把灯安装部件9定位并和安装到背反光镜8上。 By the U-shaped section member 9b is mounted to the location of the notch portion 8b is formed on the back of the reflector, the lamp and mounting member 9 is positioned and mounted on the back of the mirror 8. 结果,灯10被固定到背反光镜8上。 As a result, the lamp 10 is fixed to the back 8 on the mirror. 引线(未示出)被从灯10的两端引出,且它们每一个各通过一个反相器(未示出)与一个外部电源(未示出)相连。 Leads (not shown) are drawn out from both ends of the lamp 10, and through each of which a respective inverter (not shown) to an external power source (not shown).

现在,将说明本实施例的液晶显示器件的操作。 Now, the operation of the liquid crystal display device of the present embodiment will be explained. 当电源馈送到图2所示的灯10时,灯10发光。 When power is fed to the lamp 10 shown in FIG. 2, the lamp 10 emits light. 从灯10发出的光直接入射到漫射器5上,或被背反光镜8所反射之后入射到漫射器5上。 After the light emitted from the lamp 10 is directly incident on the diffuser 5, or reflected back mirror 8 is incident on the diffuser 5. 这样入射到漫射器5上的光,穿过漫射器,从而被散射而变得均匀,之后,进入液晶板2的显示部分2a。 Such light incident on the diffuser 5, through the diffuser so as to be scattered and become uniform, then, the liquid crystal display panel 2 into the portion 2a. 受连接基板2b控制的显示部分2a有选择地透射入射光,并将其生成色彩。 Receiving a display portion 2a is connected to the control board 2b selectively transmitting incident light, and generate its color. 结果,在显示部分2a的表面一侧,形成一个图象。 As a result, the surface of the display portion 2a, an image is formed.

在这个实施例的液晶显示器件中,由于槽12d以及凸起13c都形成于框6内,因此有可能影响漫射器5和液晶板2的定位,并对它们进行支承。 In the liquid crystal display device of this embodiment, since the protrusions 13c and grooves 12d are formed in the frame 6, and therefore may affect the positioning of the diffuser 5 and the liquid crystal panel 2, and supports them. 所以,有可能省略在传统液晶显示器件中所使用的定位部件、金属底座以及树脂框(参见图1)。 Therefore, it is possible the positioning member in a conventional liquid crystal display device is used, the metal base and the resin frame (see FIG. 1) is omitted. 除此之外,由于反射器12b容纳在框6内,而灯10安装在背反光镜8上,因此有可能省略传统液晶显示器件中所使用的侧反射器(参见图1),由此,可以减少液晶显示器件内的器件数目。 In addition, since the reflector 12b housed in the housing 6, while the lamp 10 is mounted on the back of the mirror 8, it is possible to omit the side reflector conventional liquid crystal display device used (see FIG. 1), whereby, you can reduce the number of components in the liquid crystal display device. 这样,通过减少所使用的器件数目,可以更容易地安装液晶显示器件。 Thus, by reducing the number of components used can be more easily mounted liquid crystal display device. 由于使用的器件数目变少、安装工作变得更轻松,所以液晶显示器件的成本降低了。 Since the number of devices used is reduced, the installation work becomes easier, so the cost of the liquid crystal display device is reduced. 此外,由于可以省略金属底座和树脂框,因此有可能使图象框区域变窄。 Further, since the metal base and the resin block may be omitted, it is possible that the image frame area is narrowed.

在液晶显示器件的这个实施例中,灯10安装到背反光镜8上,因此,在更换灯10的时候,可通过拆除背反光镜8,而对所有灯进行更换。 In this embodiment, a liquid crystal display device, the lamp 10 is mounted to the back of the mirror 8, and therefore, when replacing the lamp 10, the mirror can be obtained by removal of the back 8, but for all lamp replacement. 结果,提高了灯更换工作的效率。 As a result, improve the efficiency of the lamp replacement work.

另外,在液晶显示器件的这个实施例中,由于灯10是通过由橡胶构成的灯安装部件9安装在背反光镜8上,因此有可能缓冲外部振动和冲击,因此防止了灯10的损坏。 Further, in this embodiment, a liquid crystal display device, since the lamp 10 by a lamp mounting member formed of a rubber mounting 9 on the back of the mirror 8, it is possible to buffer an external vibration and impact, thus preventing damage to the lamp 10. 在使凹口部分形成于侧反射器内以支承灯的传统方法中,凹口部分的增加降低了侧反射器的优点,同时难以使侧反射器上的反射区域进一步变窄,因此不可能在液晶显示器件内使用许多灯。 In the concave portion formed in the opening side of the reflector lamp support in a conventional manner, the notch portion is reduced to increase the advantages of the side reflector, while it is difficult to reflection region on the side of the reflector is further narrowed, it is impossible in many light using a liquid crystal display device. 另一方面,在依据本发明的这个实施例中,可以使灯10的数目多于已有技术中的灯数目,这是因为灯10受灯安装部件9的支承。 On the other hand, in accordance with this embodiment of the present invention, it is possible that the number of lamps 10 than the number of lamps in the prior art, since the lamp 10 by the lamp mounting member 9 is supported. 所以,有可能提高显示部分2a的亮度,并使亮度调节范围加宽。 Therefore, it is possible to increase the brightness of the display portion 2a, and the brightness adjustment range is widened. 除此之外,通过提高灯10的数目,有可能改善亮度的均匀性,由此,有可能缩短灯10和液晶板2之间的距离,因此有可能使液晶显示器件更薄。 In addition, by increasing the number of lamps 10, it is possible to improve luminance uniformity, whereby it is possible to shorten the distance between the lamp 10 and the liquid crystal panel 2, it is possible to make the liquid crystal display device thinner.

另外,在这个实施例的液晶显示器件中,由于框6由树脂构成,因此,即便框6与由玻璃构成的液晶板2的显示区域2a相接触,也不用担心会损坏显示部分2a。 Further, the liquid crystal display device in this embodiment, since the frame 6 is made of resin, and therefore, even if the display area of ​​the frame 6 and the liquid crystal panel 2 made of glass 2a is in contact, do not worry about damage to the display portion 2a. 因此,有可能省略传统的液晶显示器件中所使用的垫片(参见图1)。 Thus, it is possible to pad in conventional liquid crystal display device used (see FIG. 1) is omitted. 结果,有可能进一步降低所使用的器件数目,并进一步降低成本。 As a result, it is possible to further reduce the number of devices used, and to further reduce costs. 此外,由于框6由树脂构成,因此没有必要在液晶板2的连接基板2b和框6之间提供一个绝缘部件,也不需要利用绝缘薄膜来覆盖用于灯10的引线(未示出),这样有条件进一步降低成本。 Further, since the frame 6 is made of resin, there is no need to provide an insulating member between the connection substrate 2b of the liquid crystal panel 2 and the frame 6, does not need to be covered with an insulating film 10 for the lamp leads (not shown), In this way the conditions to further reduce costs.

另外,由于框6是由两个短边部件12和两个长边部件13构成的,所以,在液晶显示器件的安装中,安装用于框6的液晶板2、漫射器5以及背反光镜8的工作变得更轻松。 Further, since the frame 6 is composed of two short sides and two long-side member 12 formed of members 13, so that the liquid crystal display device in the mounting, the mounting 2, the diffuser 5 and a back reflector for the liquid crystal panel 6 of the box 8 mirror work easier. 此外,可以减小用于制造框6的模具的尺寸,从而能够进一步降低成本。 Further, to reduce the size of the mold for manufacturing the frame 6, whereby the cost can be further reduced. 由于框1由金属构成,因此有可能使框1具有屏蔽性。 Since the frame 1 made of a metal, it is possible to make the frame 1 has a shielding property.

尽管本实施例中所用的框6是由短边以及长边部件12、13构成的,但框6也可以是一个完整的部件,由此,尽管用于制造框6的模具尺寸变大,但可以进一步减少液晶显示器件内所用的器件的数目。 Although the block used in the embodiment 6 of the present embodiment is composed of a short side and the long side members 12 and 13 made of, but the frame 6 may be a full member, whereby, although the dimensions of the mold for manufacturing the frame 6 is increased, but It may further reduce the number of liquid crystal display device used in the device. 尽管本实施例中所用的背反光镜8是由树脂构成的,但它也可以由金属构成,或可以包括象铝或铝合金这样的金属及其上涂敷的白色树脂。 Although the present embodiment used in the back mirror 8 is made of a resin, but it may be made of metal, or may comprise such as aluminum or an aluminum alloy metallic coating and the white resin. 尽管本实施例中所用的灯安装部件9是由橡胶构成的,但它也可以由另一种材料构成。 While the lamp mounting member used in the embodiment 9 of the present embodiment is made of rubber, but it may be formed of another material. 通过使用热传导性优异的材料来构成灯安装部件,使得热量可以有效地从灯10中辐射出。 By using a material having excellent thermal conductivity to constitute the lamp mounting member such that heat can be efficiently radiated from the lamp 10.

在发明中,可以将相邻凹口部分8b之间的空间设置得窄于传统的液晶显示器件,这样,可以以大于灯10数目的数目预先形成背反光镜8内的凹口部分8b,由此,可以在安装液晶显示器件的时候,选择灯10的适当数目以及布局。 In the invention, the space between the adjacent recess portions 8b disposed narrower than the conventional liquid crystal display device, so that the number may be greater than the number of lamps 10 are formed in advance in the notch portion 8b back mirror 8 by here, at the time of mounting the liquid crystal display device, select the appropriate number and layout of the lamp 10. 还可以在液晶显示器件已经使用了一段时期之后,方便地改变灯10的数目和布局。 Also may be performed after the liquid crystal display device has been used for some time, and easily change the layout of the number of lamp 10. 另外,也不用在背反光镜内形成凹口部分8b,也可以将灯安装部件9安装到背反光镜8上。 Further, without forming a back reflector within the notch portion 8B, the lamp may be mounted to the back member 9 is mounted on the mirror 8. 如此,就有可能设定用于背反光镜8的灯安装部件9的所需要的安装位置,因此,可以任意设定灯10的数目和位置。 Thus, it is possible to set a desired position for mounting the back reflector lamp mounting member 8, 9, therefore, it may be arbitrarily set the number and position of the lamp 10. 因此,当使用液晶显示器件后,由于随时间发生的恶化而需要更换灯时,相对于它们的初始数目和位置,可以很容易地改变灯的数目和位置。 Thus, when the liquid crystal display device, due to deterioration over time occurs while the lamp needs to be replaced, with respect to their initial position and number, you can easily change the number and position of the lamp. 另外,尽管在这个例子中,背反光镜8是通过螺钉被连接到框1上的,但也可以通过安装或通过使用双涂层粘合带等手段,将背反光镜连接到框1上。 Further, although in this case, the back mirror 8 is connected to the frame 1 by screws, but may be, the back mirror means are connected by using a double coated adhesive tape or the like to the frame 1 or by mounting.
