本新型是有關於一種導光元件，且特別是有關於一種導光板及其在背光模組與顯示裝置的應用。 The present invention relates to a light guiding element, and more particularly to a light guiding plate and its application in a backlight module and a display device.
一般使用在背光模組之導光板具有入光面、出光面以及反射面。光源所提供之光線由導光板之入光面進入導光板中，由導光板之出光面射出。其中，在導光板的出光面上通常會設有橫向的V形微結構，以使進入導光板的光線在出光前能夠更均勻地混合。 Generally, the light guide plate used in the backlight module has a light incident surface, a light exit surface, and a reflective surface. The light provided by the light source enters the light guide plate from the light incident surface of the light guide plate, and is emitted from the light exit surface of the light guide plate. Wherein, a lateral V-shaped microstructure is generally provided on the light-emitting surface of the light guide plate, so that the light entering the light guide plate can be more uniformly mixed before the light is emitted.
然而，此種橫向的V形微結構具有較高的指向性。如此一來，當導光板的表面出現顆粒或其他缺陷時，將使得光線在通過導光板時出現干擾，而影響導光板之光學外觀。 However, such lateral V-shaped microstructures have higher directivity. As a result, when particles or other defects appear on the surface of the light guide plate, the light will cause interference when passing through the light guide plate, thereby affecting the optical appearance of the light guide plate.
因此，本新型之一目的就是在提供一種導光板、背光模組及顯示裝置，其可霧化通過導光板之表面瑕疵的光線，進而可提升整體背光模組及顯示裝置的出光品質。 Therefore, an object of the present invention is to provide a light guide plate, a backlight module and a display device, which can atomize the light passing through the surface of the light guide plate, thereby improving the light quality of the entire backlight module and the display device.

依據本新型之再一實施例，上述之每一個條狀結構的延伸方向係平行於入光面，且髮絲結構的延伸方向係平行於條狀結構的延伸方向。 According to still another embodiment of the present invention, the extending direction of each of the strip structures is parallel to the light incident surface, and the extending direction of the hairline structure is parallel to the extending direction of the strip structure.
依據本新型之再一實施例，上述之每一該些條狀結構中，遠離該至少一主表面的該些髮絲結構之排列密度，較靠近該至少一主表面的該些髮絲結構的排列密度大。 According to still another embodiment of the present invention, in each of the strip structures, the arrangement density of the hair structures away from the at least one main surface is closer to the hair structures of the at least one main surface. The arrangement density is large.
根據本新型之上述目的，另提出一種背光模組。此背光模組包含前述之導光板以及光源。光源鄰設於導光板之入光面，其中光源包含電路板以及複數個發光二極體。這些發光二極體係設置在電路板上。 According to the above object of the present invention, a backlight module is further proposed. The backlight module comprises the aforementioned light guide plate and a light source. The light source is disposed adjacent to the light incident surface of the light guide plate, wherein the light source comprises a circuit board and a plurality of light emitting diodes. These light emitting diode systems are placed on the circuit board.
根據本新型之上述目的，又提出一種背光模組。此背光模組包含前述之導光板以及光源。光源鄰設於導光板之入光面，其中光源包含電路板以及複數個發光二極體。這些發光二極體係設置在電路板上。其中，在每一個條狀結構中，對應於這些發光二極體之間的髮絲結構的排列密度，較對應於這些發光二極體之髮絲結構的排列密度大。 According to the above object of the present invention, a backlight module is further proposed. The backlight module comprises the aforementioned light guide plate and a light source. The light source is disposed adjacent to the light incident surface of the light guide plate, wherein the light source comprises a circuit board and a plurality of light emitting diodes. These light emitting diode systems are placed on the circuit board. Wherein, in each strip structure, the arrangement density of the hair structure corresponding to the light-emitting diodes is larger than the arrangement density of the hair structure corresponding to the light-emitting diodes.
根據本新型之上述目的，另提出一種顯示裝置。此顯示裝置包含前述之背光模組以及顯示面板。顯示面板位於導光板的前方。 According to the above object of the present invention, a display device is further proposed. The display device includes the foregoing backlight module and a display panel. The display panel is located in front of the light guide.
由上述可知，本新型除了可透過條狀結構來提高整體導光板的出光效果外，更可透過髮絲結構來霧化導光板表面因製作缺陷而產生的過亮或過暗的區域，而可減少因導光板的缺陷而產生的出光瑕疵，進而可提升整體背光模組及顯示裝置的出光均勻度。 It can be seen from the above that in addition to the strip-like structure, the present invention can improve the light-emitting effect of the overall light-guiding plate, and can further illuminate the surface of the light-guiding plate due to defects caused by manufacturing defects through the hair structure. The light exiting due to defects of the light guide plate is reduced, thereby improving the uniformity of light output of the entire backlight module and the display device.

FIG. 3 is a partial schematic view of a backlight module according to a second embodiment of the present invention; FIG. 4 is a side view of a light guide plate according to a third embodiment of the present invention; 5] is a side view showing a light guide plate according to a fourth embodiment of the present invention; and FIG. 6 is a schematic view showing a device of a display device according to an embodiment of the present invention.
請同時參照圖1及圖2，其係分別繪示依照本新型之第一實施方式之一種背光模組之局部裝置示意圖以及局部俯視圖。本實施方式之背光模組100包含導光板200以及光源300。光源300包含電路板310以及複數個發光二極體320設置在電路板310上，其中這些發光二極體320與電路板310電性連接。光源300係設置在導光板200的一側，可產生光線而射至導光板200。如圖1及圖2所示，導光板200包含主體210、複數個條狀結構220以及複數個髮絲結構230。條狀結構220係設置在主體210上，髮絲結構230則是分布在條狀結構220的表面。藉此，透過條狀結構220可混合從導光板200射出之光線，而透過髮絲結構230則可霧化光線，藉此可減少導光板200因製作缺陷而產生的出光瑕疵，進而可提升整體背光模組100的出光均勻度。 Please refer to FIG. 1 and FIG. 2 simultaneously, which are schematic diagrams of partial devices and partial top views of a backlight module according to a first embodiment of the present invention. The backlight module 100 of the present embodiment includes a light guide plate 200 and a light source 300. The light source 300 includes a circuit board 310 and a plurality of light emitting diodes 320 disposed on the circuit board 310. The light emitting diodes 320 are electrically connected to the circuit board 310. The light source 300 is disposed on one side of the light guide plate 200 to generate light and hit the light guide plate 200. As shown in FIGS. 1 and 2 , the light guide plate 200 includes a main body 210 , a plurality of strip structures 220 , and a plurality of hair shaft structures 230 . The strip structure 220 is disposed on the body 210, and the hairline structure 230 is distributed on the surface of the strip structure 220. Thereby, the light emitted from the light guide plate 200 can be mixed through the strip structure 220, and the light can be atomized through the hair structure 230, thereby reducing the light exit pupil caused by the manufacturing defects of the light guide plate 200, thereby improving the overall light. The uniformity of light emission of the backlight module 100.
請繼續參照圖1及圖2，導光板200的主體210具有入光面211以及至少一主表面。在本實施例中，主表面有兩個，其中一主表面為出光面212，另一主表面則為反射面213，且出光面212與反射面213係分別連接於入光面211的相對兩側。條狀結構220係排列於出光面212上，且每一個條狀結構220的延伸方向係平行於入光面211。髮絲結構230分佈於每一個條狀結構之220表面上。在本實施例中，如圖2所示，這些髮絲結構230的延伸方向係垂直於條狀結構220的延伸方向。而且，在每一個條狀結構220之表面中，這些髮絲結構230具有規則性的疏密排列。 Referring to FIG. 1 and FIG. 2 , the main body 210 of the light guide plate 200 has a light incident surface 211 and at least one main surface. In this embodiment, there are two main surfaces, one of which is a light-emitting surface 212, and the other of which is a reflective surface 213, and the light-emitting surface 212 and the reflective surface 213 are respectively connected to the opposite sides of the light-incident surface 211. side. The strip structures 220 are arranged on the light exit surface 212, and each strip structure 220 extends in a direction parallel to the light incident surface 211. A hairline structure 230 is distributed over the surface 220 of each strip structure. In the present embodiment, as shown in FIG. 2, the extension directions of the hairline structures 230 are perpendicular to the extending direction of the strip structure 220. Moreover, in the surface of each strip structure 220, these hairline structures 230 have a regular dense arrangement.
在一些實施例中，條狀結構220之表面上的髮絲結構230可依據發光二極體320的光線照射方向、或其他需求而具有規則性的疏密排列。如圖2所示，每一個發光二極體320所發出之光線係以發散方式射入導光板200中，故在本實施例之條狀結構220中，位於發光二極體320之間的髮絲結構230的排列密度較位於對應於發光二極體320位置之髮絲結構230的排列密度大。 In some embodiments, the hairline structure 230 on the surface of the strip structure 220 can have a regular dense arrangement depending on the direction of light illumination of the LED diode 320, or other requirements. As shown in FIG. 2, the light emitted by each of the LEDs 320 is incident on the light guide plate 200 in a divergent manner. Therefore, in the strip structure 220 of the embodiment, the light between the LEDs 320 is located between the LEDs 320. The arrangement density of the filament structures 230 is greater than the arrangement density of the filament structures 230 located at positions corresponding to the LEDs 320.
如圖2所示，發光二極體320可在導光板200上形成數個第一區A1以及數個第二區A2。在此所指的第一區A1係指對應每一個發光二極體320所發出光線直接照射的位置。第二區A2則是指位於相鄰之發光二極體320之間，且與發光二極體320交錯而沒有直接被光線照射到的位置。因此，在本實施例中，位於第一區A1的髮絲結構230的排列密 度較位於第二區A2的髮絲結構230的排列密度疏，藉此可調整光線均齊度，進而可提升整體背光模組100出光效果。 As shown in FIG. 2, the LEDs 320 can form a plurality of first regions A1 and a plurality of second regions A2 on the light guide plate 200. The first area A1 referred to herein refers to a position directly irradiated with light emitted from each of the light-emitting diodes 320. The second area A2 refers to a position between the adjacent light-emitting diodes 320 and interlaced with the light-emitting diodes 320 without being directly irradiated with light. Therefore, in the present embodiment, the arrangement of the hairline structures 230 located in the first zone A1 is dense. The density of the hairline structure 230 located in the second area A2 is less, so that the uniformity of the light can be adjusted, thereby improving the light-emitting effect of the overall backlight module 100.
欲陳明者，本實施方式之條狀結構220設置在出光面212並非用以限制本新型。在其他實施例中，條狀結構220亦可依據設計需求而設計在反射面213上。此外，本新型之條狀結構220的延伸方向亦不限於平行於入光面211，在其他實施例中，條狀結構220的延伸方向亦可依據不同設計需求而調整。 It is to be understood that the strip structure 220 of the present embodiment is disposed on the light exit surface 212 and is not intended to limit the present invention. In other embodiments, the strip structure 220 can also be designed on the reflective surface 213 according to design requirements. In addition, the extending direction of the strip structure 220 of the present invention is not limited to being parallel to the light incident surface 211. In other embodiments, the extending direction of the strip structure 220 may also be adjusted according to different design requirements.
在其他實施例中，導光板上的髮絲結構亦可有不同的延伸方向。請參照圖3，其係繪示依照本新型之第二實施方式之一種背光模組之局部裝置示意圖。本實施方式之背光模組400的結構大致上與背光模組100相同，差異僅在於背光模組400中的導光板500具有不同的髮絲結構。如圖3所示，導光板500包含主體510、複數個條狀結構520以及複數個髮絲結構530。其中，主體510具有入光面511以及至少一主表面。在本實施例中，主表面有兩個，其中一主表面為出光面512，且另一主表面則為反射面513，且出光面512與反射面513係分別連接於入光面511的相對兩側。如圖3所示，條狀結構520係排列於出光面512上，且每一個條狀結構520的延伸方向係平行於511入光面。髮絲結構530則是分佈於每一個條狀結構之520之表面上。其中，在每一個條狀結構520之表面中，這些髮絲結構530的延伸方向係平行於條狀結構520的延伸方向，且這些髮絲結構530同樣具有規則性的疏密排列。 In other embodiments, the hairline structure on the light guide plate may have different extending directions. Please refer to FIG. 3 , which is a schematic diagram of a partial device of a backlight module according to a second embodiment of the present invention. The structure of the backlight module 400 of the present embodiment is substantially the same as that of the backlight module 100. The only difference is that the light guide plate 500 in the backlight module 400 has different hair structure. As shown in FIG. 3, the light guide plate 500 includes a main body 510, a plurality of strip structures 520, and a plurality of hairline structures 530. The main body 510 has a light incident surface 511 and at least one main surface. In this embodiment, there are two main surfaces, one of which is a light-emitting surface 512, and the other of which is a reflective surface 513, and the light-emitting surface 512 and the reflective surface 513 are respectively connected to the light-incident surface 511. On both sides. As shown in FIG. 3, the strip structures 520 are arranged on the light exit surface 512, and each strip structure 520 extends in a direction parallel to the 511 light incident surface. The hairline structure 530 is distributed over the surface of each of the strips 520. Wherein, in the surface of each strip structure 520, the extension directions of the hairline structures 530 are parallel to the extending direction of the strip structures 520, and the hairline structures 530 also have a regular dense arrangement.
請繼續參照圖3所示，在本實施例的條狀結構520中，遠離出光面512的髮絲結構530之排列密度較靠近出光面512的髮絲結構530的排列密度大。在本實施例中，由於條狀結構520為凸出結構，且條狀結構520較遠離出光面512的部分表面容易在製作上或搬運過程中出現製作瑕疵或碰撞缺陷，故在可能出現瑕疵的部分設置髮絲結構530可霧化光線，以避免光線因通過瑕疵部分而導致出光不均的問題。欲陳明者，在不同的實施例中，條狀結構520亦可依據需求而設計成凹陷結構。 Continuing to refer to FIG. 3, in the strip structure 520 of the present embodiment, the arrangement density of the hairline structures 530 away from the light exit surface 512 is greater than the arrangement density of the hairline structures 530 near the light exit surface 512. In this embodiment, since the strip-shaped structure 520 is a convex structure, and a part of the surface of the strip-shaped structure 520 that is farther away from the light-emitting surface 512 is likely to be defective in manufacturing or collision during production or handling, defects may occur in the present invention. The hairline structure 530 is partially disposed to atomize the light to avoid the problem of uneven light emission due to passing through the ridge portion. It is to be understood that in various embodiments, the strip structure 520 can also be designed as a recessed structure depending on the requirements.
欲陳明者，在前述實施例之背光模組100及400中，條狀結構220及520的截面形狀為三角形並非用以限制本新型。在其他實施例中，條狀結構及的截面形狀亦可為其他形狀。請參照圖4，其係繪示依照本新型之第三實施方式之一種導光板之側視圖。在圖4所示實施例中，導光板600的條狀結構620之延伸方向平行於入光面611，且截面形狀為梯形。在本實施例中，髮絲結構可依據需求而設計成平行或垂直於條狀結構620的延伸方向，且具有規則的疏密排列，以達到與前述實施例相同之目的。 It is to be understood that in the backlight modules 100 and 400 of the foregoing embodiments, the triangular shapes of the strip structures 220 and 520 are not limited to limit the present invention. In other embodiments, the strip structure and the cross-sectional shape may be other shapes. Please refer to FIG. 4 , which is a side view of a light guide plate according to a third embodiment of the present invention. In the embodiment shown in FIG. 4, the extending direction of the strip structure 620 of the light guide plate 600 is parallel to the light incident surface 611, and the cross-sectional shape is trapezoidal. In the present embodiment, the hairline structure can be designed to be parallel or perpendicular to the extending direction of the strip structure 620 according to requirements, and has a regular dense arrangement to achieve the same purpose as the foregoing embodiment.
又如圖5所示，圖5係繪示依照本新型之第四實施方式之一種導光板之側視圖。在圖5所示實施例中，導光板700的條狀結構720之延伸方向平行於入光面711，且截面形狀為半圓形。在本實施例中，髮絲結構同樣可依據需求而設計成平行或垂直於條狀結構720的延伸方向，且具有規則的疏密排列，以達到與前述實施例相同之目的。 As shown in FIG. 5, FIG. 5 is a side view of a light guide plate according to a fourth embodiment of the present invention. In the embodiment shown in FIG. 5, the strip structure 720 of the light guide plate 700 extends in a direction parallel to the light incident surface 711, and has a semicircular cross section. In the present embodiment, the hairline structure can also be designed to be parallel or perpendicular to the extending direction of the strip structure 720 according to requirements, and has a regular dense arrangement to achieve the same purpose as the foregoing embodiment.
另請參照圖6，其係繪示依照本新型之一實施方式之一種顯示裝置之側視圖。本實施方式之顯示裝置800包含如圖1所示之背光模組100以及顯示面板810。如圖6所示，顯示面板810係設置在背光模組100之導光板200的出光側。顯示裝置800透過導光板200上的條狀結構220與髮絲結構230同樣可達到前述霧化與均勻化光線之目的，故在此不再贅述。欲陳明者，本案實施例以圖1所示之背光模組100應用於顯示裝置800中僅用來作為示範說明用，並非用以限制本新型。前述其他實施例的導光板，例如導光板500、600及700亦可應用於顯示裝置中，以產生同樣之效果。 Please refer to FIG. 6 , which is a side view of a display device according to an embodiment of the present invention. The display device 800 of the present embodiment includes a backlight module 100 and a display panel 810 as shown in FIG. 1 . As shown in FIG. 6 , the display panel 810 is disposed on the light exiting side of the light guide plate 200 of the backlight module 100 . The display device 800 can achieve the aforementioned atomization and homogenization of light through the strip structure 220 on the light guide plate 200, and therefore will not be described herein. It is to be understood that the backlight module 100 shown in FIG. 1 is applied to the display device 800 for illustrative purposes only, and is not intended to limit the present invention. The light guide plates of the other embodiments described above, such as the light guide plates 500, 600, and 700, can also be applied to a display device to produce the same effect.
由上述本新型實施方式可知，本新型除了可透過條狀結構來提高整體導光板的出光效果外，更可透過髮絲結構來霧化導光板表面因製作缺陷而產生的過亮或過暗的區域，而可減少因導光板的缺陷而產生的出光瑕疵，進而可提升整體背光模組及顯示裝置的出光均勻度。 According to the embodiment of the present invention, in addition to the strip-like structure, the present invention can improve the light-emitting effect of the overall light-guiding plate, and can further illuminate the surface of the light-guiding plate due to defects caused by manufacturing defects through the hairline structure. The area can reduce the exit pupil caused by the defects of the light guide plate, thereby improving the uniformity of the light output of the entire backlight module and the display device.
