Description

具遮光模組之背光模組以及使用此背光模組的顯示裝置 Backlight module with light shielding module and display device using the same

本發明係關於一種背光模組以及使用此背光模組的顯示裝置。 The present invention relates to a backlight module and a display device using the same.

近年來液晶顯示裝置(Liquid Crystal Display)已成為各類顯示裝置之主流。例如家用的電視、個人電腦、膝上型電腦、監視器、行動電話及數位相機等,均為大量使用液晶顯示裝置之產品。其中應用於液晶顯示裝置之背光模組(Backlight Module)係用於供應有著足夠亮度及分佈均勻的光源,以使液晶顯示裝置能正常顯示影像。 In recent years, liquid crystal display devices have become the mainstream of various types of display devices. For example, home televisions, personal computers, laptops, monitors, mobile phones, and digital cameras are all products that use a large number of liquid crystal display devices. The backlight module used in the liquid crystal display device is used for supplying a light source with sufficient brightness and uniform distribution to enable the liquid crystal display device to display images normally.

如圖1所示之習知液晶顯示裝置90,包含面板模組80、背光模組10、支撐框50以及後殼70。其中,背光模組10包含導光板20、光學膜片組30、光源40及反射片41,其採用的是側光式背光模組,亦即採導光板20側面入光端22入光之方式,具有厚度薄的優勢。然而,如圖1所示,背光模組10之光源40發出之光線91,因為入射角θ小於全反射角而不會在出光面24產生全反射之光線,所以會由導光板20靠近入光端22之一端射出,且當定位導光板20或光學膜片組30的墊塊53、54位移,光線91將從導光板20與墊塊53間或光學膜片組與墊塊54間的間隙(未圖示)漏出,或直接經由光學膜片組30折射而出,從而產生漏光現象。另一方面,由於光源40 與入光端22間具有間隙G,故光線92亦有可能由此間隙漏出。以上背光模組及液晶顯示裝置有改善的空間。 The conventional liquid crystal display device 90 shown in FIG. 1 includes a panel module 80, a backlight module 10, a support frame 50, and a rear case 70.

The backlight module is used, that is, the side of the light guide plate 20 enters the light end 22 and enters the light. , has the advantage of thin thickness. However, as shown in FIG. 1 , the light 91 emitted by the light source 40 of the backlight module 10 does not generate a total reflection light on the light exit surface 24 because the incident angle θ is smaller than the total reflection angle, so that the light guide plate 20 approaches the light. One end of the end 22 is ejected, and when the spacers 53, 54 of the positioning light guide plate 20 or the optical film group 30 are displaced, the light 91 will be separated from the light guide plate 20 and the spacer 53 or between the optical film group and the spacer 54. (not shown) leaks out or is directly refracted through the optical film group 30, thereby causing light leakage. On the other hand, due to the source 40 There is a gap G between the light incident end 22 and the light incident end 22, so that the light ray 92 may leak through the gap. The above backlight module and liquid crystal display device have improved space.

如圖2A所示之較佳實施例,本發明之背光模組100係供與面板模組800、支撐框500以及後殼700共同形成顯示裝置900。後殼700與支撐框500共同形成容置空間990以容置背光模組100及光學膜片組300。背光模組100較佳採用側光式之入光設計,且包含導光板200、光源模組400以及遮光模組600,較佳更包含反射片410。導光板200具有相鄰的入光面220及出光面240。光源模組400對應於入光面220設置,亦即毗鄰於入光面220,且與入光面220間具有間隙G。光源模組400可以包含為發光二極體(Light Emitting Diodes,LED)或冷陰極螢光燈管(Cold Cathode Fluorescent Lamp;CCFL)等光源。背光模組100進一步包含光學膜片組300設置於出光面240上。以較佳實施例而言,光學膜片組300鄰接於遮光模組600,形成接續設置於導光板200上之態樣。換言之,光學 膜片組300與遮光模組600並列且接續設置於出光面240上。 As shown in FIG. 2A, the backlight module 100 of the present invention is used to form the display device 900 together with the panel module 800, the support frame 500, and the rear case 700. The rear case 700 and the support frame 500 together form an accommodating space 990 for accommodating the backlight module 100 and the optical film set 300. The backlight module 100 preferably adopts an edge-lighting light-in design, and includes a light guide plate 200, a light source module 400, and a light-shielding module 600, and preferably further includes a reflective sheet 410. The light guide plate 200 has adjacent light incident surfaces 220 and light exit surfaces 240. The light source module 400 is disposed corresponding to the light incident surface 220 , that is, adjacent to the light incident surface 220 , and has a gap G between the light incident surface 220 and the light incident surface 220 . The light source module 400 may include a light source such as a Light Emitting Diodes (LED) or a Cold Cathode Fluorescent Lamp (CCFL). The backlight module 100 further includes an optical film set 300 disposed on the light exit surface 240. In the preferred embodiment, the optical film set 300 is adjacent to the light shielding module 600 and is formed to be successively disposed on the light guide plate 200. In other words, optics The diaphragm group 300 is juxtaposed with the light shielding module 600 and is successively disposed on the light emitting surface 240.

如圖2A所示之較佳實施例,遮光模組600包含遮光基板620與第一反射基材640,其中遮光基板620係設置於光源模組400上,且延伸覆蓋至出光面240,第一反射基材640設置於遮光基板620之底面,且位於間隙G上。換言之,遮光模組600部分設置於出光面240上鄰近入光端220之部分,並包含遮光基板620及第一反射基材640設置於遮光基板620之第一面621上。其中,遮光模組600及第一反射基材640較佳為條狀設置,並沿導光板200之側邊延伸。第一反射基材640之面積不小於間隙G之(投影)面積。 As shown in FIG. 2A, the light-shielding module 620 includes a light-shielding substrate 620 and a first reflective substrate 640. The light-shielding substrate 620 is disposed on the light source module 400 and extends to cover the light-emitting surface 240. The reflective substrate 640 is disposed on the bottom surface of the light shielding substrate 620 and is located on the gap G. In other words, the light-shielding module 600 is partially disposed on the light-emitting surface 240 adjacent to the light-incident end 220 , and includes a light-shielding substrate 620 and a first reflective substrate 640 disposed on the first surface 621 of the light-shielding substrate 620 . The light shielding module 600 and the first reflective substrate 640 are preferably disposed in strips and extend along the sides of the light guide plate 200. The area of the first reflective substrate 640 is not less than the (projection) area of the gap G.

在較佳實施例中,遮光模組600包含膠層660設置於遮光基板620之底面,且鄰接於第一反射基材640,並位於出光240面及遮光基板620之間。遮光模組600並包含第二反射基材644設置於光源模組400下,且位於第一反射基材640的投影位置,且延伸至間隙G下方。以不同角度觀之,第一反射基材640面積小於第一面621,且第一面621未與第一反射基材640重疊部分具有膠層660,係貼合於出光面240上,第一反射基材640更延伸覆蓋光源模組400與入光端220間之間隙G。其中,遮光模組600較佳包含膠層660與第一反射基材640並列設置於第一面621上,膠層660係連接第一面621且在出光面240上未與第一反射基材640重疊。膠層660的折射率較佳係大於等於導光板200的折射率。膠層660之厚度較佳則不大於或小於第一反射基材640之厚度,使出光面240較第一反射基 材640之反射面641接近第一面621。 In the preferred embodiment, the light-shielding module 600 is disposed on the bottom surface of the light-shielding substrate 620 and adjacent to the first reflective substrate 640 and between the light-emitting surface 240 and the light-shielding substrate 620. The light shielding module 600 further includes a second reflective substrate 644 disposed under the light source module 400 and located at a projection position of the first reflective substrate 640 and extending below the gap G. The first reflective substrate 640 has a smaller area than the first surface 621, and the first surface 621 does not overlap the first reflective substrate 640, and has a glue layer 660 attached to the light-emitting surface 240. The reflective substrate 640 further extends to cover the gap G between the light source module 400 and the light incident end 220. The light-shielding module 600 preferably includes a glue layer 660 and a first reflective substrate 640 disposed on the first surface 621, and the glue layer 660 is connected to the first surface 621 and is not connected to the first reflective substrate on the light-emitting surface 240. 640 overlap. The refractive index of the adhesive layer 660 is preferably greater than or equal to the refractive index of the light guide plate 200. The thickness of the adhesive layer 660 is preferably not greater than or less than the thickness of the first reflective substrate 640, so that the light exit surface 240 is larger than the first reflective base. The reflective surface 641 of the material 640 is adjacent to the first surface 621.

如圖3所示,由於出光面240上鄰近入光端220之部分設置有遮光模組600,故原本因為入射角小於全反射角而不會在出光面240產生全反射之光線901,將由遮光基板620直接遮蔽,避免其由導光板200靠近入光端220之一端射出,以及當定位導光板200或光學膜片組300的墊塊530、540位移而使光線910從導光板200與墊塊530間或光學膜片組300與墊塊530間的間隙(未圖示)漏出,而產生漏光現象。另一方面,由於第一反射基材640延伸覆蓋光源模組400與入光端220間之間隙G,故光線903,不僅有遮光基板620遮蔽,更有第一反射基材640將其反射,因此可避免其由光源模組400與入光端220間之間隙G漏出,。換言之,第一反射基材640之設置不僅解決了發生在光源模組400與入光端220間之間隙G之漏光問題,更提高了光線的利用率。 As shown in FIG. 3, since the light-shielding module 600 is disposed on the portion of the light-emitting surface 240 adjacent to the light-incident end 220, the light 901 that would not be totally reflected on the light-emitting surface 240 because the incident angle is smaller than the total reflection angle will be shielded from light. The substrate 620 is directly shielded from being emitted from one end of the light guide plate 200 near the light incident end 220, and when the spacers 530, 540 of the positioning light guide plate 200 or the optical film set 300 are displaced to cause the light 910 to pass from the light guide plate 200 and the spacer A gap (not shown) between the 530 or the optical film group 300 and the spacer 530 leaks out to cause light leakage. On the other hand, since the first reflective substrate 640 extends to cover the gap G between the light source module 400 and the light incident end 220, the light ray 903 is shielded not only by the light shielding substrate 620 but also by the first reflective substrate 640. Therefore, it can be avoided that the gap G between the light source module 400 and the light incident end 220 leaks out. In other words, the arrangement of the first reflective substrate 640 not only solves the problem of light leakage occurring in the gap G between the light source module 400 and the light incident end 220, but also improves the utilization of light.

第一反射基材640可為具反射性之塗層或貼片。在如圖2A所示之較佳實施例中,第一反射基材640係延伸至完全覆蓋光源模組400,進一步減少漏光的可能性,並增加結構穩定性。然而在不同實施例中,可以因為製程便利性或節省材料成本等的考量,選擇如圖2B所示讓第一反射基材640覆蓋或如圖2C所示僅部分覆蓋光源模組400,亦即第一反射基材640延伸長度至少大於間隙G的寬度,可遮蔽間隙G而減少漏光的產生。第一反射基材640較佳係由光源模組400所支撐。進一步而言,遮光模組600之第一反射基材640之一端較佳由光源 模組400支撐,另一端則由導光板200支撐。第一反射基材640與光源模組400間較佳可另設置雙面膠帶或其他連接用品;然在不同實施例中,第一反射基材640本身亦可略帶黏著力,以與光源模組400連接;或者第一反射基材640不與光源模組400直接接觸,而於其間夾有一間隙以利散熱。 The first reflective substrate 640 can be a reflective coating or patch. In the preferred embodiment shown in FIG. 2A, the first reflective substrate 640 extends to completely cover the light source module 400, further reducing the likelihood of light leakage and increasing structural stability. However, in different embodiments, the first reflective substrate 640 may be covered as shown in FIG. 2B or only partially covered by the light source module 400 as shown in FIG. 2C, because of process convenience or material cost saving considerations, that is, The first reflective substrate 640 has an extended length that is at least greater than the width of the gap G, and can mask the gap G to reduce the occurrence of light leakage. The first reflective substrate 640 is preferably supported by the light source module 400. Further, one end of the first reflective substrate 640 of the light shielding module 600 is preferably a light source The module 400 is supported and the other end is supported by the light guide plate 200. Preferably, a double-sided tape or other connecting article is disposed between the first reflective substrate 640 and the light source module 400; however, in different embodiments, the first reflective substrate 640 itself may also have a slight adhesive force to the light source die. The group 400 is connected; or the first reflective substrate 640 is not in direct contact with the light source module 400, and a gap is interposed therebetween for heat dissipation.

如圖4所示之實施例,遮光模組600並包含第二反射基材644,與反射片410並列且接續設置於後殼700上並覆蓋光源模組400與入光端220間之間隙G,且與第一反射基材640隔著間隙G相對。藉此,可進一步避免光線905由第一反射基材640對向之光源模組400與入光端220間之間隙G漏出,並提高光線的利用率。 As shown in FIG. 4 , the light shielding module 600 includes a second reflective substrate 644 , which is disposed along the reflective sheet 410 and is disposed on the rear case 700 and covers the gap G between the light source module 400 and the light incident end 220 . And facing the first reflective substrate 640 with a gap G therebetween. Thereby, the light 905 can be further prevented from leaking from the gap G between the light source module 400 and the light incident end 220 of the first reflective substrate 640, and the utilization of light can be improved.

如圖2A所示之較佳實施例,支撐框500環繞面板模組800,包含凸緣510位於遮光模組600相反於第一面621之第二面622。以不同角度觀之,凸緣510係向面板模組800之中心延伸而成。面板模組800較佳係為液晶面板;然亦可為其他需要背光源之顯示面板。 As shown in FIG. 2A , the support frame 500 surrounds the panel module 800 , and the flange 510 is disposed on the second surface 622 of the light shielding module 600 opposite to the first surface 621 . Viewed from a different perspective, the flange 510 extends toward the center of the panel module 800. The panel module 800 is preferably a liquid crystal panel; however, it may be another display panel that requires a backlight.

支撐框500進一步包含墊塊530、540分別夾設於凸緣510及第二面622以及凸緣510及光學膜片組300之間,用以定位導光板200與光學膜片組300,並可進一步限制遮光模組600之位移。其中,位於導光板200上方的墊塊530,一部分隔著遮光模組600間接設置於導光板200上,另一部分則隔著遮光模組600間接設置於第一反射基材640上。在較佳實施例中,墊塊應也可以採條狀設置,並沿導光板200之側邊延伸。墊塊 530之光穿透性可低於遮光基板620之光穿透性,以進一步提高光遮蔽效果。然而在不同實施例中,墊塊530之光穿透性可低於遮光基板620之光穿透性,例如使用彈性較佳但光穿透性較高的材料,以提高固定效果。墊塊530之材質較佳係可具有壓縮性,例如橡膠或導電泡棉,以產生適當的壓迫效果,且可降低組裝公差帶來的問題。 The support frame 500 further includes spacers 530 and 540 respectively interposed between the flange 510 and the second surface 622 and the flange 510 and the optical film group 300 for positioning the light guide plate 200 and the optical film group 300, and The displacement of the light shielding module 600 is further limited. The pad 530 located above the light guide plate 200 is partially disposed on the light guide plate 200 via the light shielding module 600, and the other portion is indirectly disposed on the first reflective substrate 640 via the light shielding module 600. In a preferred embodiment, the spacers should also be strip-shaped and extend along the sides of the light guide 200. Pad The light transmittance of 530 may be lower than the light transmittance of the light-shielding substrate 620 to further enhance the light shielding effect. However, in different embodiments, the light transmittance of the spacer 530 may be lower than that of the light shielding substrate 620, for example, a material having better elasticity but higher light transmittance is used to improve the fixing effect. The material of the spacer 530 is preferably compressible, such as rubber or conductive foam, to produce a suitable pressing effect, and to reduce the problems caused by assembly tolerances.
