Abstract
Description
本發明是有關於一種背光模組，且特別是有關於一種具有反射片的背光模組。The present invention relates to a backlight module, and more particularly to a backlight module having a reflective sheet.
目前的電子裝置多利用平面顯示模組進行畫面的顯示，其中又以液晶顯示模組的技術較為純熟且普及化。然而，由於液晶顯示模組的顯示面板本身無法發光，故在顯示面板下方具有背光模組以提供顯示畫面所需光線。At present, electronic devices often use a flat display module to display images, and the technology of the liquid crystal display module is more sophisticated and popular. However, since the display panel of the liquid crystal display module itself cannot emit light, a backlight module is provided under the display panel to provide light required for displaying the screen.
一般來說，側入式(side-edge)背光模組包含光源及導光板等構件，導光板的主要功能是將線光源經由介質傳導與能量發散機制與調變方式產生一均勻面光源。此外，可於導光板的背面及側面配置反射片，使導光板於背面及側面所出射的光線被反射片反射回導光板中並從出光面射出，以提高光使用率。藉由膠層將反射片膠合於導光板的側面為一種常見的固定方式，然而由於膠層內部結構的不均勻，使得通過膠層的光線產生散射等現象，導致導光板出現亮暈，影響背光模組的出光效果。Generally, a side-edge backlight module includes a light source and a light guide plate. The main function of the light guide plate is to generate a uniform surface light source through a medium conduction and energy divergence mechanism and a modulation mode. In addition, a reflective sheet may be disposed on the back surface and the side surface of the light guide plate, so that the light emitted from the light guide plate on the back surface and the side surface is reflected by the reflection sheet back into the light guide plate and emitted from the light exit surface to improve the light utilization rate. Gluing the reflective sheet to the side of the light guide plate by the adhesive layer is a common fixing method. However, due to the uneven structure of the inner layer of the adhesive layer, the light passing through the adhesive layer is scattered, which causes the light guide plate to appear bright and halo, affecting the backlight. The light output of the module.
中華民國專利編號TW I295399揭露一種背光模組，其導光板側面以雙面膠貼附反射片，以提升光線使用效率。中華民國專利編號TW 201035641揭露導光板與多個光源之間包含多個反射片，這些反射片與這些光源交錯排列。中華民國專利編號TW 201111879揭露一種背光模組，其多個第一黏合材料配置於反射片與導光片之間，並黏合反射片、導光片以及發光元件。The Republic of China Patent No. TW I295399 discloses a backlight module in which a side surface of a light guide plate is attached with a double-sided tape to enhance the light use efficiency. The Republic of China Patent No. TW 201035641 discloses that a plurality of reflective sheets are included between the light guide plate and the plurality of light sources, and the reflective sheets are staggered with the light sources. The Republic of China Patent No. TW 201111879 discloses a backlight module in which a plurality of first bonding materials are disposed between the reflective sheet and the light guiding sheet, and the reflective sheet, the light guiding sheet and the light emitting element are bonded.
本發明提出一種背光模組，具有較佳的出光效果。The invention provides a backlight module with better light-emitting effect.
本發明的其他目的和優點可以從本發明所揭露的技術特徵中得到進一步的了解。Other objects and advantages of the present invention will become apparent from the technical features disclosed herein.
為達上述之一或部份或全部目的或是其他目的，本發明之一實施例提供一種背光模組，包括一導光板、一膠層、一第一反射片及至少一光源。導光板具有一出光面、一背面、一第一側面及一第二側面。出光面相對於背面。第一側面及第二側面分別連接於出光面與背面之間。膠層膠合於第一側面。第一側面被膠層覆蓋的區域的面積小於第一側面的總面積的四分之三。第一反射片具有一反射面。反射面膠合於膠層而將第一反射片固定於第一側面。光源配置於第二側面。In an embodiment of the present invention, a backlight module includes a light guide plate, a glue layer, a first reflection sheet, and at least one light source. The light guide plate has a light emitting surface, a back surface, a first side surface and a second side surface. The light exit surface is opposite to the back side. The first side surface and the second side surface are respectively connected between the light emitting surface and the back surface. The glue layer is glued to the first side.

基於上述，在本發明的上述實施例中，由於第一側面被膠層覆蓋的區域的面積小於第一側面的總面積的四分之三，因此可降低光源射入導光板的光線通過膠層的機率，進而改善導光板的亮暈現象，提升背光模組的出光效果。Based on the above, in the above embodiment of the present invention, since the area of the area covered by the glue layer on the first side is smaller than three quarters of the total area of the first side, the light entering the light guide plate through the glue layer can be reduced. The probability of the light guide plate is improved, thereby improving the light-emitting effect of the backlight module.

Therefore, the directional terminology used is for the purpose of illustration and not limitation.
圖1為本發明一實施例之背光模組的立體圖。圖2為圖1之背光模組的局部剖面圖。圖3為圖1之第一反射片及膠層的示意圖。請參考圖1至圖3，本實施例的背光模組100包括一導光板110、一膠層120、一第一反射片130及至少一光源140(繪示為多個)。導光板110具有一出光面112、一背面114、一第一側面116及一第二側面118。出光面112相對於背面114，且第一側面116及第二側面118分別連接於出光面112與背面114之間。膠層120膠合於第一側面116，且第一反射片130的反射面132膠合於膠層120而將第一反射片130固定於第一側面116。這些光源140配置於第二側面118，且適於發出光線至導光板110。FIG. 1 is a perspective view of a backlight module according to an embodiment of the invention. 2 is a partial cross-sectional view of the backlight module of FIG. 1. 3 is a schematic view of the first reflective sheet and the adhesive layer of FIG. 1. Referring to FIG. 1 to FIG. 3 , the backlight module 100 of the present embodiment includes a light guide plate 110 , a glue layer 120 , a first reflection sheet 130 , and at least one light source 140 (shown as a plurality). The light guide plate 110 has a light emitting surface 112, a back surface 114, a first side surface 116 and a second side surface 118. The light-emitting surface 112 is opposite to the back surface 114, and the first side surface 116 and the second side surface 118 are connected between the light-emitting surface 112 and the back surface 114, respectively. The adhesive layer 120 is glued to the first side 116 , and the reflective surface 132 of the first reflective sheet 130 is glued to the adhesive layer 120 to fix the first reflective sheet 130 to the first side 116 . The light sources 140 are disposed on the second side 118 and are adapted to emit light to the light guide plate 110.
在本實施例中，導光板110的第一側面116被膠層120覆蓋的區域116a的面積小於第一側面116的總面積的四分之三。藉此，可降低這些光源140射入導光板110的光線通過膠層120的機率，進而改善導光板110的亮暈現象，提升背光模組100的出光效果。In the present embodiment, the area of the region 116a of the first side 116 of the light guide plate 110 covered by the glue layer 120 is smaller than three quarters of the total area of the first side surface 116. Thereby, the probability that the light of the light source 140 entering the light guide plate 110 passes through the adhesive layer 120 can be reduced, thereby improving the bright halo phenomenon of the light guide plate 110 and improving the light output effect of the backlight module 100.
在本實施例中，導光板110的第一側面116被膠層120覆蓋的區域116a的面積約為第一側面116的總面積的三分之二，然本發明不以此為限，在其它實施例中，導光板110的第一側面116被膠層120覆蓋的區域116a的面積可為小於第一側面116的總面積的四分之三的其它適當大小。舉例來說，在能夠將第一反射片130穩固地膠合於導光板110的第一側面116的前提下，可減少膠層120的尺寸，將第一側面116被膠層120覆蓋的區域116a的面積降低至第一側面116的總面積的二之一或更小，以進一步改善導光板110的亮暈現象。In this embodiment, the area of the first side 116 of the light guide plate 110 covered by the adhesive layer 120 is about two-thirds of the total area of the first side 116. However, the present invention is not limited thereto. In an embodiment, the area of the region 116a of the first side 116 of the light guide plate 110 covered by the glue layer 120 may be other suitable size smaller than three-quarters of the total area of the first side surface 116. For example, under the premise that the first reflective sheet 130 can be firmly glued to the first side 116 of the light guide plate 110, the size of the adhesive layer 120 can be reduced, and the region 116a of the first side 116 covered by the adhesive layer 120 can be The area is reduced to one of two or less of the total area of the first side 116 to further improve the brightness of the light guide plate 110.

However, the present invention is not limited thereto. In other embodiments, the backlight module 100 can be used for other suitable devices.
圖4為習知一種背光模組的局部剖面圖。圖5為圖2之背光模組的亮暈現象與圖4之背光模組的亮暈現象的比較圖。圖5中的橫軸為以導光板110/210的第一側面116/216為基準點沿方向D的位移(Distance)，縱軸為亮暈現象的強度(Intensity)。在圖2的背光模組100的配置方式之下，通過膠層120的光線在導光板110形成的亮暈現象的強度沿方向D的變化如圖5的實線L1所示。4 is a partial cross-sectional view of a conventional backlight module. FIG. 5 is a comparison diagram of the bright halo phenomenon of the backlight module of FIG. 2 and the bright halo phenomenon of the backlight module of FIG. 4. The horizontal axis in FIG. 5 is the displacement in the direction D with the first side surface 116/216 of the light guide plate 110/210 as a reference point, and the vertical axis is the intensity of the bright halo phenomenon. In the arrangement of the backlight module 100 of FIG. 2, the intensity of the bright halo phenomenon formed by the light of the glue layer 120 on the light guide plate 110 changes along the direction D as shown by the solid line L1 of FIG.
在圖4的背光模組200中，第一反射片230藉由膠層220被膠合於導光板210，導光板210的第一側面216被膠層220覆蓋的區域216a的面積約為第一側面216的總面積的90%。在此情況下，通過膠層220的光線在導光板210形成的亮暈現象的強度沿方向D的變化如圖5的虛線L2所示。比較圖5中的實線L1及虛線L2可看出，在橫軸為0至d的範圍內，習知背光模組200的導光板210的亮暈現象較為嚴重，而本實施例之背光模組100藉由縮減膠層120的分佈面積以改善導光板110的亮暈現象。In the backlight module 200 of FIG. 4, the first reflective sheet 230 is glued to the light guide plate 210 by the adhesive layer 220. The area 216a of the first side 216 of the light guide plate 210 covered by the adhesive layer 220 is about the first side. 90% of the total area of 216. In this case, the change in the intensity of the bright halo phenomenon formed by the light of the glue layer 220 on the light guide plate 210 in the direction D is as shown by the broken line L2 of FIG. Comparing the solid line L1 and the broken line L2 in FIG. 5, it can be seen that the light-emitting panel 210 of the conventional backlight module 200 has a relatively bright phenomenon in the range of 0 to d on the horizontal axis, and the backlight mode of the embodiment is more serious. The group 100 improves the brightness of the light guide plate 110 by reducing the distribution area of the glue layer 120.
請參考圖1，本實施例的背光模組100除了配置了第一反射片130之外，更在導光板110的其它側面配置了第一反射片130’及第一反射片130”。第一反射片130’及第一反射片130”的配置方式類似於第一反射片130的配置方式，於此不再贅述。此外，如圖1及圖2所示，背光模組100更包括一第二反射片150，第二反射片150配置於導光板110的背面114，用以反射這些光源140發出的光線。Referring to FIG. 1 , in addition to the first reflective sheet 130 , the backlight module 100 of the present embodiment further includes a first reflective sheet 130 ′ and a first reflective sheet 130 ′′ on the other side of the light guide plate 110 .

In the process of bonding the first reflective sheet 130 to the light guide plate 110, the appropriately sized adhesive layer 120 may be glued to the reflective surface 132 of the first reflective sheet 130 to cover the area of the region 132a of the reflective surface 132 covered by the adhesive layer 120. Less than three-quarters of the total area of the reflective surface 132, the glue layer 120 on the first reflective sheet 130 is then glued to the first side 116 of the light guide plate 110.

The distance between the glue layer 120 and the side edge 132c is greater than the distance between the glue layer 120 and the side edge 132b, so that the glue layer 120 is located closer to the side edge 132b, and at most three-quarters of the reflection surface 132 is glued. Layer 120 is covered. The present invention does not limit the distribution position and shape of the adhesive layer 120, and the following is exemplified by the drawings.
