一种用于遮蔽液晶显示器光源的反射板 A reflector for shielding light sources of liquid crystal displays

技术领域technical field

本发明涉及液晶显示器的光源,尤其涉及液晶显示器光源的反射板结构。The invention relates to a light source of a liquid crystal display, in particular to a reflection plate structure of a light source of a liquid crystal display.

背景技术Background technique

当前,笔记本电脑显示器的发光源均采用LED光源的方式,但是,该类型的机种往往会在LED光源发光时,造成一系列的云纹(mura)。例如,组装有LED光源和导光板(LGP,Light GuidePlate)的框架表面产生形变,向外卷曲时就可能使光源从框架与导光板间的缝隙中出射。Currently, the light sources of notebook computer monitors all use LED light sources. However, this type of models often causes a series of moiré (mura) when the LED light source emits light. For example, the surface of the frame assembled with the LED light source and the light guide plate (LGP, Light Guide Plate) is deformed, and when it is curled outward, the light source may emerge from the gap between the frame and the light guide plate.

为了尽可能避免上述LED云纹的生成,一种解决方案是提升框架本身的成型精度,提高组装工厂的组装能力。另外,还可以直接在框架与导光板之间的缝隙中粘附一条白色的反射片,以便阻挡LED光源欲从该处串出的部分光。然而,贴附白色反射片会给组装工艺带来诸多不便,而且这种技术措施还包括侵犯他人专利的潜在风险。In order to avoid the generation of the above-mentioned LED moiré as much as possible, one solution is to improve the forming accuracy of the frame itself and improve the assembly capacity of the assembly factory. In addition, a white reflective sheet can also be directly attached to the gap between the frame and the light guide plate, so as to block part of the light that the LED light source intends to string out from there. However, attaching a white reflective sheet will bring a lot of inconvenience to the assembly process, and this technical measure also includes the potential risk of infringing other people's patents.

有鉴于此,如何设计一种用于遮蔽液晶显示器光源的反射板,是业内技术人员亟待解决的一项课题。In view of this, how to design a reflector for shielding the light source of the liquid crystal display is a problem to be solved urgently by technical personnel in the industry.

具体实施方式Detailed ways

下面参照附图,对本发明的具体实施方式进行详细描述。Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

如前所述,在现有技术的液晶显示器光源中,为了避免LED光源从框架与导光板之间的缝隙串出部分光,于该缝隙内粘附一白色的反射片。但是,该反射片贴合于导光板的上表面时,会给组装工艺带来诸多不便。As mentioned above, in the conventional liquid crystal display light source, in order to prevent the LED light source from emitting part of the light from the gap between the frame and the light guide plate, a white reflective sheet is adhered in the gap. However, when the reflective sheet is attached to the upper surface of the light guide plate, it will bring a lot of inconvenience to the assembly process.

为此,本发明设计了一种新型结构的反射板,以下主要结合图1进行详细说明。具体地,图1示出依据本发明的一实施例,用于遮蔽液晶显示器光源的反射板的结构组成示意图。参照图1,本发明的反射板包括第一反射片10、第二反射片12和骑缝部14。在组装时,将该反射板弯折成“U”型,其中第一反射片10与液晶显示器的导光板的上表面贴合,以及第二反射片12与该导光板的下表面贴合。针对骑缝部14,具有第一骑缝线141、第二骑缝线142和多个开口143,更为具体地,第一骑缝线141与第一反射片10相接触,第二骑缝线142与第二反射片12相接触,也就是说,第一反射片10和骑缝部14以第一骑缝线141为分界,第二反射片12和骑缝部14以第二骑缝线142为分界。For this reason, the present invention designs a reflective plate with a new structure, which will be described in detail below mainly with reference to FIG. 1 . Specifically, FIG. 1 shows a schematic diagram of the structure and composition of a reflector for shielding a light source of a liquid crystal display according to an embodiment of the present invention. Referring to FIG. 1 , the reflective plate of the present invention includes a first reflective sheet 10 , a second reflective sheet 12 and a bridging portion 14 . During assembly, the reflector is bent into a "U" shape, wherein the first reflector 10 is bonded to the upper surface of the light guide plate of the liquid crystal display, and the second reflector 12 is bonded to the lower surface of the light guide plate. For the bridging part 14, there are first bridging line 141, second bridging line 142 and a plurality of openings 143. More specifically, the first bridging line 141 is in contact with the first reflective sheet 10, and the second bridging line 142 is in contact with the second reflective sheet 12, that is to say, the first reflective sheet 10 and the bridging portion 14 are bounded by the first bridging line 141, and the second reflecting sheet 12 and the bridging portion 14 are separated by the second bridging line 142. demarcation.

此外,骑缝部14还具有多个开口143,每一开口对应于液晶显示器的每个光源,优选地,这些光源是LED光源。并且,为了提高产品的性能,将每一开口143的形状大小设置为与对应光源的尺寸大小相同。当弯折该反射板时,由于第一反射片10和第二反射片12均对应贴合于导光板的各自表面,光源可以穿过开口并与导光板侧壁相接触。应当指出,本发明的反射板是一整块平板,并且第一反射片10的长度小于第二反射片12的长度。In addition, the bridging part 14 also has a plurality of openings 143, each opening corresponds to each light source of the liquid crystal display, preferably, these light sources are LED light sources. Moreover, in order to improve the performance of the product, the shape and size of each opening 143 are set to be the same as the size of the corresponding light source. When the reflector is bent, since the first reflector 10 and the second reflector 12 are attached to the respective surfaces of the light guide plate, the light source can pass through the opening and contact the side wall of the light guide plate. It should be noted that the reflection plate of the present invention is a whole flat plate, and the length of the first reflection sheet 10 is smaller than the length of the second reflection sheet 12 .

依据一实施例,为了尽可能地使第一反射片10贴合于导光板的上表面,且第二反射片12贴合于导光板的下表面,将第一骑缝线141与第二骑缝线142间的距离设置成导光板的厚度数值。此外,为了加强反射板的骑缝部14与导光板的侧壁(即,导光板与骑缝部14相贴合的表面)的可靠连接,在与骑缝部14相贴合的导光板表面上粘附至少一条双面胶带(图中未示),通过双面胶带来固定反射板和导光板的接触位置。优选地,提供两条双面胶带,且每条双面胶带对应地设置于与骑缝部14相贴合的导光板表面的一端。也就是说,当这两条双面胶带设置于导光板的侧壁,并且反射板弯折成U状时,将骑缝部14可靠连接与导光板。According to one embodiment, in order to make the first reflective sheet 10 bonded to the upper surface of the light guide plate as much as possible, and the second reflective sheet 12 to be bonded to the lower surface of the light guide plate, the first stitching line 141 and the second saddle The distance between the sutures 142 is set to the thickness value of the light guide plate. In addition, in order to strengthen the reliable connection between the bridging part 14 of the reflector and the side wall of the light guide plate (that is, the surface where the light guide plate and the bridging part 14 are bonded), the surface of the light guide plate that is bonded to the bridging part 14 is adhered At least one double-sided adhesive tape (not shown in the figure) is used to fix the contact position of the reflective plate and the light guide plate through the double-sided adhesive tape. Preferably, two double-sided adhesive tapes are provided, and each double-sided adhesive tape is correspondingly disposed at one end of the surface of the light guide plate adjoining the bridging portion 14 . That is to say, when the two double-sided adhesive tapes are disposed on the sidewall of the light guide plate and the reflector is bent into a U shape, the bridging portion 14 is reliably connected to the light guide plate.

本领域的普通技术人员应当理解,骑缝部14的开口143所对应的导光板侧壁的那部分表面,在LED光源插入后会与LED接触,也就是说,该部分表面最好不必粘有双面胶带。优选地,该双面胶带的长度为开口143向外一侧(即图1中的上部开口143的上一直线)与骑缝部的边缘(即图1中的反射板的上边缘)之间的距离。Those of ordinary skill in the art should understand that that part of the surface of the side wall of the light guide plate corresponding to the opening 143 of the bridging portion 14 will contact the LED after the LED light source is inserted, that is to say, this part of the surface preferably does not need to be glued with double masking tape. Preferably, the length of the double-sided adhesive tape is between the outward side of the opening 143 (that is, the upper straight line of the upper opening 143 in FIG. 1 ) and the edge of the bridging portion (that is, the upper edge of the reflector in FIG. 1 ). distance.

采用本发明的用于遮蔽液晶显示器光源的反射板,通过具有两条骑缝线的骑缝部,将其很容易地弯折成U状,以便分别贴合于导光板的上表面和下表面,进而遮蔽LED光源的出射光,避免生成LED云纹。此外,骑缝部中还开设与LED光源的尺寸大小相同的多个开口,从而使LED光源能够通过反射板的开口组装至预定位置。Using the reflecting plate for shielding the light source of the liquid crystal display of the present invention, it can be easily bent into a U shape through the bridging portion with two bridging lines, so as to be attached to the upper surface and the lower surface of the light guide plate respectively, Furthermore, the outgoing light of the LED light source is shielded to avoid the generation of LED moiré. In addition, a plurality of openings having the same size as the LED light source are opened in the bridging portion, so that the LED light source can be assembled to a predetermined position through the openings of the reflective plate.

上文中,参照附图描述了本发明的具体实施方式。但是,本领域中的普通技术人员能够理解,在不偏离本发明的精神和范围的情况下,还可以对本发明的具体实施方式作各种变更和替换。这些变更和替换都落在本发明权利要求书所限定的范围内。Hereinbefore, specific embodiments of the present invention have been described with reference to the accompanying drawings.
