具体实施方式Detailed ways
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
本申请实施例提供一种背光模组01，如图1所示，包括胶框10以及设置于胶框10内的光源20和导光板30。The embodiment of the present application provides a backlight module 01 , as shown in FIG. 1 , including a plastic frame 10 , a light source 20 and a light guide plate 30 disposed in the plastic frame 10 .
其中，该导光板30固定安装于胶框10上。Wherein, the light guide plate 30 is fixedly installed on the plastic frame 10 .
此外，光源20的柔性电路板(英文全称：Flexible Printed Circuit，英文简称FPC)的一部分位于导光板30的出光侧，该部分FPC靠近导光板30的一侧表面上设置有反射层40。In addition, part of the flexible printed circuit (full English name: Flexible Printed Circuit, FPC) of the light source 20 is located on the light emitting side of the light guide plate 30 , and a reflective layer 40 is provided on the surface of this part of the FPC close to the light guide plate 30 .
需要说明的是，上述光源20可以为由多颗LED成排设置的LED灯条，或者荧光管、电致发光片等。本申请对此不做限定。It should be noted that the above-mentioned light source 20 may be an LED light bar with a plurality of LEDs arranged in a row, or a fluorescent tube, an electroluminescent sheet, or the like. This application does not limit this.
基于此，上述LED打件于FPC上。由于FPC的面积大于LED，因此，FPC的一部分如图1所示，延伸出位于LED的出光面，该部分称为灯前的FPC；而FPC的有一部分延伸出该LED的背面(与出光面相对的一侧表面)，该部分称为灯后的FPC。在此情况下，上述FPC中位于导光板30的出光侧的部分，如图1所示，即为该灯前的FPC。Based on this, the above-mentioned LEDs are packaged on the FPC. Since the area of the FPC is larger than that of the LED, a part of the FPC extends out of the light-emitting surface of the LED as shown in Figure 1, and this part is called the FPC in front of the lamp; and a part of the FPC extends out of the back of the LED (with the light-emitting surface The opposite side surface), this part is called the FPC behind the lamp. In this case, the part of the above FPC located on the light emitting side of the light guide plate 30, as shown in FIG. 1, is the FPC in front of the lamp.
此外，如图2所示，所述导光板30在靠近光源出光侧的一侧具有楔形部301。其中，该楔形部301厚度较大的一端靠近光源20，厚度较小的一端远离光源20。这样一来，由于该导光板30中除了楔形部301以外的部分与显示面板的显示区域相对应，且该导光板30中除了楔形部301以外的部分的厚度较小，因此可以减小该背光模组01中与上述显示区域相对应的部分的厚度。In addition, as shown in FIG. 2 , the light guide plate 30 has a wedge-shaped portion 301 on a side close to the light output side of the light source. Wherein, the thicker end of the wedge-shaped portion 301 is close to the light source 20 , and the thinner end is away from the light source 20 . In this way, since the part of the light guide plate 30 except the wedge-shaped part 301 corresponds to the display area of the display panel, and the thickness of the part of the light guide plate 30 except the wedge-shaped part 301 is small, the backlight can be reduced. The thickness of the part of module 01 corresponding to the above display area.
基于此，为了避免光源20发出的光线在光源20的出光侧发生漏光，可选的，上述楔形部301靠近光源20一侧的后大于或等于光源20的厚度。这样一来，该光源20的出光侧可以被楔形部301靠近该光源20的一侧表面完全覆盖，从而使得该光源20发出的光线全部入射至导光板30内部，达到解决光源20漏光的问题，进而能够提升光源20发出光线的利用率。Based on this, in order to prevent the light emitted by the light source 20 from leaking at the light output side of the light source 20 , optionally, the thickness of the wedge-shaped portion 301 on the side close to the light source 20 is greater than or equal to the thickness of the light source 20 . In this way, the light emitting side of the light source 20 can be completely covered by the surface of the side of the wedge-shaped portion 301 close to the light source 20, so that all the light emitted by the light source 20 is incident into the inside of the light guide plate 30, so as to solve the problem of light leakage from the light source 20. Furthermore, the utilization rate of the light emitted by the light source 20 can be improved.
在此基础上，上述光源20的灯前的FPC位于该楔形部301的出光侧。此时，可选的，该楔形部301的楔形面(即该楔形部301的出光侧所在的倾斜的表面)与该灯前的FPC下表面(靠近楔形部301一侧的表面)的反射层40直接接触。On this basis, the FPC in front of the light source 20 is located at the light emitting side of the wedge-shaped portion 301 . At this time, optionally, the wedge surface of the wedge 301 (that is, the inclined surface where the light-emitting side of the wedge 301 is located) and the reflective layer on the lower surface of the FPC in front of the lamp (the surface near the side of the wedge 301 ) 40 direct contact.
其中，上述反射层40可以为白色薄膜层。该白色薄膜层可以是涂覆在灯前的FPC下表面上的白油。这样一来，由于光源20发出的光线通常为白光，在此情况下，采用上述白色薄膜层作为反射层40时，如图2所示，由楔形部301的楔形面出射的光线照射至反射层40，并被该反射层40反射回导光板30中的光线仍然为白光，从而避免改变导光板30中光线的颜色。Wherein, the reflective layer 40 may be a white thin film layer. The white film layer may be white oil coated on the lower surface of the FPC in front of the lamp. In this way, since the light emitted by the light source 20 is usually white light, in this case, when the above-mentioned white film layer is used as the reflective layer 40, as shown in FIG. 40 , and the light reflected by the reflective layer 40 back into the light guide plate 30 is still white light, so as to avoid changing the color of the light in the light guide plate 30 .
此外，可选的，楔形部301的楔形面与背光模组01的底面之间的夹角为5°～15°。In addition, optionally, the included angle between the wedge-shaped surface of the wedge-shaped portion 301 and the bottom surface of the backlight module 01 is 5°˜15°.
由上述可知，本申请实施例提供的背光模组01中的导光板30固定安装于胶框10上。这样一来，上述光源20的FPC中位于导光板30出光侧的一部分(即上述灯前的FPC)与导光板30的楔形部301之间无需设置用于固定导光板30的胶带。在此基础上，由于该灯前的FPC在靠近导光板30的楔形部301一侧表面上设置有反射层40，因此，光源20(例如LED)入射至导光板30中的光线中的一部分，如图3所示，会由导光板30的一部分(楔形部301)折射出去，并照射至上述反射层40。在此情况下，上述反射层40能够将入射光重新反射至导光板30内部，从而可以提高光源20发出光线的利用率，减少光线损失，达到提高背光模组01整体发光亮度的目的。It can be seen from the above that the light guide plate 30 in the backlight module 01 provided by the embodiment of the present application is fixedly installed on the plastic frame 10 . In this way, there is no need to set an adhesive tape for fixing the light guide plate 30 between the part of the FPC of the light source 20 located on the light emitting side of the light guide plate 30 (that is, the FPC in front of the lamp) and the wedge-shaped portion 301 of the light guide plate 30 . On this basis, since the FPC in front of the lamp is provided with a reflective layer 40 on the surface near the wedge-shaped portion 301 of the light guide plate 30, a part of the light rays incident on the light guide plate 30 by the light source 20 (such as an LED) As shown in FIG. 3 , it is refracted by a part (wedge portion 301 ) of the light guide plate 30 and irradiated to the above-mentioned reflective layer 40 . In this case, the reflective layer 40 can re-reflect the incident light to the inside of the light guide plate 30 , thereby improving the utilization rate of the light emitted by the light source 20 , reducing light loss, and achieving the purpose of improving the overall luminance of the backlight module 01 .
综上所述，本申请提供的提升背光模组01亮度的方案中，无需增大单颗LED的亮度，且无需提升构成导光板30或其他光学膜片的材料的辉度。因此能够有效减小生产成本。To sum up, in the solution for improving the brightness of the backlight module 01 provided by the present application, there is no need to increase the brightness of a single LED, and it is not necessary to increase the brightness of the materials constituting the light guide plate 30 or other optical films. Therefore, the production cost can be effectively reduced.
需要说明的是，本申请中，“上”、“下”、“左”、“右”等方位术语是相对于附图中的背光模组01或导光板30示意置放的方位来定义的，应当理解到，这些方向性术语是相对的概念，它们用于相对于的描述和澄清，其可以根据背光模组01或导光板30所放置的方位的变化而相应地发生变化。It should be noted that in this application, orientation terms such as "upper", "lower", "left", and "right" are defined relative to the orientation where the backlight module 01 or the light guide plate 30 are schematically placed in the drawings , it should be understood that these directional terms are relative concepts, and they are used for relative description and clarification, which may change accordingly according to the change of the orientation of the backlight module 01 or the light guide plate 30 .
基于此，为了将导光板30固定安装于胶框10上，可选的，如图4或图7所示，可以在胶框10上设置L形膜材承载台101。Based on this, in order to fix the light guide plate 30 on the plastic frame 10, optionally, as shown in FIG. 4 or FIG.
在此基础上，如图5或图8所示，上述导光板30包括导光本体312以及设置于该导光本体312至少一侧的凸耳311。该凸耳311固定安装于上述L形膜材承载台101的底面上。On this basis, as shown in FIG. 5 or FIG. 8 , the light guide plate 30 includes a light guide body 312 and a lug 311 disposed on at least one side of the light guide body 312 . The lug 311 is fixedly installed on the bottom surface of the above-mentioned L-shaped film material supporting platform 101 .
以下，上述胶框10上设置有L形膜材承载台101以及导光板30的凸耳311的设置进行详细的说明。Hereinafter, the arrangement of the L-shaped film material carrying platform 101 and the lug 311 of the light guide plate 30 on the above-mentioned plastic frame 10 will be described in detail.
具体的，例如，如图4所示，上述凸耳311可以设置于导光本体312背离光源30的一侧。Specifically, for example, as shown in FIG. 4 , the lug 311 may be disposed on a side of the light guide body 312 away from the light source 30 .
基于此，由于背光模组01在发光过程中会产生热量，因此使得导光板30的体积发生膨胀。在此情况下，为了避免体积膨胀的导光板30不会在胶框10的挤压作用下发生变形，可选的，如图4所示，上述凸耳311与L形膜材承载台101的侧壁之间具有间隙。Based on this, since the backlight module 01 generates heat during the light emitting process, the volume of the light guide plate 30 expands. In this case, in order to prevent the volume expansion of the light guide plate 30 from being deformed under the extrusion of the plastic frame 10, optionally, as shown in FIG. There is a gap between the side walls.
其中，该间隙的宽度N可以根据构成导光板30的材料进行设定。例如，该间隙的宽度N可以为0.1mm～0.2mm之间。为了在不增加制作精度的同时，使得背光模组01内部部件之间安装紧凑，可选的，上述间隙的宽度N＝0.15mm。Wherein, the width N of the gap can be set according to the material constituting the light guide plate 30 . For example, the width N of the gap may be between 0.1 mm and 0.2 mm. In order to make the installation of internal components of the backlight module 01 compact without increasing the manufacturing precision, optionally, the width of the gap N=0.15 mm.
此外，如图5所示，设置于导光本体312背离光源30一侧的凸耳311的宽度F可以在0.2mm～0.3mm之间。为了在不增加制作精度的同时，保证导光本体312的尺寸不会发生较大的变化，可选的，上述凸耳311的宽度F＝0.25mm。In addition, as shown in FIG. 5 , the width F of the lug 311 disposed on the side of the light guide body 312 facing away from the light source 30 may be between 0.2 mm and 0.3 mm. In order to ensure that the size of the light guide body 312 does not change greatly without increasing the manufacturing precision, optionally, the width F of the above-mentioned lug 311 is 0.25 mm.
在此基础上，如图4所示，由于凸耳311需要固定于胶框10的L形膜材承载台101的底部，因此上述凸耳311距离该导光板30底部的间距G，可以根据上述L形膜材承载台101的深度进行设置，而该L形膜材承载台101的深度又有胶框10的高度决定，本申请对此不作限定。On this basis, as shown in FIG. 4 , since the lug 311 needs to be fixed on the bottom of the L-shaped film carrier 101 of the plastic frame 10, the distance G between the lug 311 and the bottom of the light guide plate 30 can be determined according to the above-mentioned The depth of the L-shaped film material supporting platform 101 is set, and the depth of the L-shaped film material supporting platform 101 is determined by the height of the plastic frame 10, which is not limited in this application.
此外，为了使得凸耳311固定于胶框10的L形膜材承载台101的底部，该凸耳311与L形膜材承载台101的底面之间设置有如图4所示的黑色双面胶带50。In addition, in order to make the lug 311 fixed on the bottom of the L-shaped film material carrying platform 101 of the plastic frame 10, a black double-sided adhesive tape as shown in Figure 4 is arranged between the lug 311 and the bottom surface of the L-shaped film material carrying platform 101 50.
其中，该黑色双面胶带50的宽度H可以略小于凸耳311的宽度F。例如，黑色双面胶带50的宽度H在0.15mm～0.25mm之间，可选的，该黑色双面胶带50的宽度H＝0.2mm。Wherein, the width H of the black double-sided adhesive tape 50 may be slightly smaller than the width F of the lug 311 . For example, the width H of the black double-sided tape 50 is between 0.15 mm and 0.25 mm. Optionally, the width H of the black double-sided tape 50 is 0.2 mm.
在此基础上，如图6所示，设置于凸耳311与L形膜材承载台101的底面之间的黑色双面胶带50可以吸收导光本体312入射至凸耳311的光线，从而可以减小导光板30背离光源20的一侧出现漏光的几率，达到减轻该位置出现亮线的现象。On this basis, as shown in FIG. 6 , the black double-sided adhesive tape 50 arranged between the lug 311 and the bottom surface of the L-shaped film material carrier 101 can absorb the light incident on the lug 311 from the light guide body 312 , so that it can The probability of light leakage on the side of the light guide plate 30 facing away from the light source 20 is reduced, so as to alleviate the phenomenon of bright lines appearing at this position.
或者，上述胶框10上设置有L形膜材承载台101以及导光板30的凸耳311的设置方式，又例如，如图7所示，凸耳311设置于与导光本体312靠近光源20的一侧相邻的至少一个侧面上。Alternatively, the plastic frame 10 is provided with an L-shaped film material carrying platform 101 and a lug 311 of the light guide plate 30. For example, as shown in FIG. on at least one side adjacent to one side of the
同理，为了防止导光板20受热变形，当导光本体312的左、右两侧均设置有上述凸耳311时，在左边的凸耳311与L形膜材承载台101的侧壁之间，以及右边的凸耳311与L形膜材承载台101的侧壁之间具有间隙，该上述左边的间隙的宽度L与右边的间隙的宽度L’可以相同，可以为0.1mm～0.2mm之间。为了在不增加制作精度的同时，使得背光模组01内部部件之间安装紧凑，可选的，上述间隙的宽度L＝L’＝0.12mm。Similarly, in order to prevent the light guide plate 20 from being deformed by heat, when the above-mentioned lugs 311 are provided on the left and right sides of the light guide body 312, between the left lug 311 and the side wall of the L-shaped film material carrying platform 101 , and there is a gap between the lug 311 on the right and the side wall of the L-shaped film carrier 101, the width L of the gap on the left and the width L' of the gap on the right can be the same, and can be between 0.1 mm and 0.2 mm between. In order to make the installation of the internal components of the backlight module 01 compact without increasing the manufacturing precision, optionally, the width of the gap L=L'=0.12mm.
此外，如图8所示，设置于靠近光源20的一侧相邻的至少一个侧面(即导光板30上除了靠近光源20的侧面，以及与该靠近光源20的侧面相对的另一个侧面以外的任意一个侧面)上的凸耳311的宽度F可以在0.2mm～0.3mm之间。为了在不增加制作精度的同时，保证导光本体312的尺寸不会发生较大的变化，可选的，上述凸耳311的宽度F＝0.25mm。In addition, as shown in FIG. 8 , at least one side adjacent to the side close to the light source 20 (that is, on the light guide plate 30 except the side close to the light source 20 and the other side opposite to the side close to the light source 20 The width F of the lug 311 on any one side) may be between 0.2 mm and 0.3 mm. In order to ensure that the size of the light guide body 312 does not change greatly without increasing the manufacturing precision, optionally, the width F of the above-mentioned lug 311 is 0.25 mm.
