Abstract
Description
本發明是有關於一種光源模組,且特別是有關於一種能應用於顯示裝置的背光模組及使用此背光模組的顯示裝置。 The present invention relates to a light source module, and more particularly to a backlight module that can be applied to a display device and a display device using the same.
液晶顯示裝置為現今普及率較高的顯示裝置之一,其主要包括液晶顯示面板與背光模組,其中背光模組用以提供液晶顯示面板所需的顯示光源。 The liquid crystal display device is one of the display devices with high popularity. The liquid crystal display device mainly includes a liquid crystal display panel and a backlight module. The backlight module is used to provide a display light source required for the liquid crystal display panel.
背光模組可分為直下式背光模組與側邊入光式背光模組,其中側邊入光式背光模組包括導光板以及配置於導光板之入光面旁的發光元件。早期的技術中,通常都是以冷陰極螢光燈管(cold cathode fluorescent lamp,CCFL)來做為發光元件。近年來,冷陰極螢光燈管已逐漸被發光二極體(light emitting diode)取代。 The backlight module can be divided into a direct-lit backlight module and a side-lit backlight module, wherein the side-lit backlight module includes a light guide plate and a light-emitting component disposed beside the light-incident surface of the light guide plate. In the early technology, a cold cathode fluorescent lamp (CCFL) was usually used as a light-emitting element. In recent years, cold cathode fluorescent tubes have been gradually replaced by light emitting diodes.
在習知技術中,發光二極體通常是設置於電路板上,並藉由膠帶來將電路板黏貼於導光板的底部。為了避免漏光,發光二極體的出光面與導光板的入光面之間需精準對位。然而,膠帶本身的厚度會造成發光二極體的出光面與導光板的入光面在導光板的厚度方向上無法精準對位而產生漏光,此將降低背光模組的光利用效率。 In the prior art, the light-emitting diodes are usually disposed on a circuit board, and the circuit board is adhered to the bottom of the light guide plate by tape. In order to avoid light leakage, the light-emitting surface of the light-emitting diode and the light-incident surface of the light guide plate need to be accurately aligned. However, the thickness of the tape itself causes the light-emitting surface of the light-emitting diode and the light-incident surface of the light guide plate to be inaccurately aligned in the thickness direction of the light guide plate to cause light leakage, which will reduce the light utilization efficiency of the backlight module.

Referring to FIG. 1 , the display device 100 of the embodiment includes a display panel 110 and a backlight module 200 . The backlight module 200 includes a light guide plate 210 and a light source assembly 220 , and the display panel 110 is disposed above the light guide plate 210 . The light guide plate 210 has a light incident surface 212 and a bottom surface 214 connected to the light incident surface 212. The light source assembly 220 includes at least one light emitting element 222, a substrate 224, and a glue 226. The light-emitting element 222 is disposed adjacent to the light-incident surface 212. The substrate 224 has a bearing surface 225 carrying the light-emitting element 222 and a recessed portion 227. The partial-bearing surface 225 is connected to the bottom surface 214 of the light guide plate 210, for example, and exposes the recessed portion 227. The glue 226 is disposed in the recess 227 and is adhered to the bottom surface 214 of the light guide plate 210, for example.
顯示面板110為非自發光顯示面板,如液晶顯示面板,而背光模組200用以提供顯示面板110所需的顯示光源。發光元件222例如是發光二極體或其他點光源,其提供的光線經由入光面212進入導光板210中,而導光板210將來自發光元件222的光線轉換成面光源。面光源從導光板210的頂面216出射,以作為顯示面板110所需的顯示光源。在頂面216與顯示面板110之間可設置光學膜片230,如稜鏡片或擴散膜等,以均勻或增亮面光源。此外,導光板210的底面214可更黏貼有反射片240,以防止底面214漏光。 The display panel 110 is a non-self-luminous display panel, such as a liquid crystal display panel, and the backlight module 200 is used to provide a display light source required by the display panel 110. The light-emitting element 222 is, for example, a light-emitting diode or other point light source, and the light provided therein enters the light guide plate 210 via the light-incident surface 212, and the light guide plate 210 converts the light from the light-emitting element 222 into a surface light source. The surface light source emerges from the top surface 216 of the light guide plate 210 to serve as a display light source required for the display panel 110. An optical film 230, such as a cymbal or a diffusion film, may be disposed between the top surface 216 and the display panel 110 to evenly or brighten the surface light source. In addition, the bottom surface 214 of the light guide plate 210 can be more adhered to the reflective sheet 240 to prevent the bottom surface 214 from leaking light.
在本實施例中,用以承載發光元件222的基板224例如為 可撓性電路板,其例如更連接至顯示面板110的周邊線路區112。然而,本發明並不限定基板224必須連接至顯示面板110的周邊線路區112。而且,基板224也可為剛性基板。此外,周邊線路區112上方可黏有膠材120,而此膠材120更黏至基板224之與周邊線路區112連接的部分。 In this embodiment, the substrate 224 for carrying the light emitting element 222 is, for example, A flexible circuit board, for example, is further connected to the peripheral line region 112 of the display panel 110. However, the present invention does not limit that the substrate 224 must be connected to the peripheral line region 112 of the display panel 110. Moreover, the substrate 224 can also be a rigid substrate. In addition, a glue 120 may be adhered over the peripheral line region 112, and the glue 120 is more adhered to a portion of the substrate 224 that is connected to the peripheral line region 112.
上述之顯示裝置100例如更包括框架130,此框架130包括圍繞導光板210的側壁132及從側壁132延伸至導光板210上方的支撐部134,而顯示面板110配置於支撐部134上。本實施例中,顯示面板110例如是由膠材140黏貼於支撐部134上,並由膠材150黏貼於光學膜片230上。上述之承載面225例如更由膠材160黏貼於側壁132的底面133。 The display device 100 further includes a frame 130. The frame 130 includes a sidewall 132 surrounding the light guide plate 210 and a support portion 134 extending from the sidewall 132 to the light guide plate 210. The display panel 110 is disposed on the support portion 134. In this embodiment, the display panel 110 is adhered to the support portion 134 by the adhesive material 140, and is adhered to the optical film 230 by the adhesive material 150. The bearing surface 225 is adhered to the bottom surface 133 of the side wall 132 by, for example, the glue material 160.
在本實施例中,配置在凹陷部227內的膠材226例如為膠帶,但不以此為限。膠材226的厚度大約等於凹陷部227的深度,亦即,用於黏貼基板224與導光板210的膠材226並不會凸出於基板224的承載面225,所以能使基板224的承載面225平整地貼附於導光板210的底面214。如此,發光元件222的出光面223與導光板210的入光面212在導光板210的厚度方向D上的對位不會受到膠材226的影響,所以能避免產生漏光,進而提升本實施例之背光模組200的光利用效率,而本實施例之顯示裝置100的光利用效率也因而提升。 In the present embodiment, the rubber 226 disposed in the recessed portion 227 is, for example, an adhesive tape, but is not limited thereto. The thickness of the adhesive material 226 is approximately equal to the depth of the recessed portion 227, that is, the adhesive material 226 for adhering the substrate 224 and the light guide plate 210 does not protrude from the bearing surface 225 of the substrate 224, so that the bearing surface of the substrate 224 can be 225 is attached to the bottom surface 214 of the light guide plate 210 in a flat manner. In this manner, the alignment between the light-emitting surface 223 of the light-emitting element 222 and the light-incident surface 212 of the light guide plate 210 in the thickness direction D of the light guide plate 210 is not affected by the glue 226, so that light leakage can be avoided, thereby improving the embodiment. The light use efficiency of the backlight module 200 is also improved by the light use efficiency of the display device 100 of the present embodiment.

在本實施例中,黏貼基板224與導光板210的膠材226是設置在基板224的凹陷部227內,所以能使基板224的承載面225平整地貼附於導光板210的頂面216。如此,發光元件222的出光面223與導光板210的入光面212在導光板210的厚度方向D上的對位不會受到膠材226的影響,所以能避免產生漏光,進而提升本實施例之背光模組200a的光利用效率,而本實施例之顯示裝置100a的光利用效率也因而提升。 In the present embodiment, the adhesive material 226 of the adhesive substrate 224 and the light guide plate 210 is disposed in the recessed portion 227 of the substrate 224, so that the bearing surface 225 of the substrate 224 can be flatly attached to the top surface 216 of the light guide plate 210. In this manner, the alignment between the light-emitting surface 223 of the light-emitting element 222 and the light-incident surface 212 of the light guide plate 210 in the thickness direction D of the light guide plate 210 is not affected by the glue 226, so that light leakage can be avoided, thereby improving the embodiment. The light use efficiency of the backlight module 200a is also improved by the light use efficiency of the display device 100a of the present embodiment.
雖然在圖1與圖5中,基板224例如是作為主電路板,其可直接連接到顯示面板110的周邊線路區112,但本發明並不 以此為限。舉例來說,如圖6所示,顯示裝置100b可更包括主電路板180,其連接至顯示面板110的周邊線路區112,而光源組件220b的基板224b例如是連接至主電路板180。 Although in FIG. 1 and FIG. 5, the substrate 224 is, for example, a main circuit board, which can be directly connected to the peripheral line region 112 of the display panel 110, the present invention does not This is limited to this. For example, as shown in FIG. 6, the display device 100b may further include a main circuit board 180 connected to the peripheral line region 112 of the display panel 110, and the substrate 224b of the light source assembly 220b is connected to the main circuit board 180, for example.
綜上所述,在本發明之背光模組中,由於將基板黏貼至導光板的膠材是設置於基板的凹陷部內,所以能避免膠材的厚度影響導光板的入光面與發光元件的出光面在導光板的厚度方向上的對位,以防止產生漏光的情形。如此,能提升本發明之背光模組及顯示裝置的光利用效率。此外,在一實施例中,因凹陷部的凹穴設置的位置避開發光元件的出光面前方,所以能減少凹穴中的膠材吸收到的光能量,進而提升本發明之背光模組及顯示裝置的光利用效率。 In the backlight module of the present invention, since the adhesive material for adhering the substrate to the light guide plate is disposed in the recessed portion of the substrate, the thickness of the adhesive material can be prevented from affecting the light incident surface of the light guide plate and the light emitting element. The illuminating surface is aligned in the thickness direction of the light guide plate to prevent light leakage. Thus, the light use efficiency of the backlight module and the display device of the present invention can be improved. In addition, in one embodiment, since the position of the recessed portion of the recessed portion avoids the front side of the light-emitting surface of the light developing element, the light energy absorbed by the adhesive material in the recessed hole can be reduced, thereby improving the backlight module of the present invention and The light utilization efficiency of the display device.
雖然本發明已以較佳實施例揭露如上,然其並非用以限定本發明,任何熟習此技藝者,在不脫離本發明之精神和範圍內,當可作些許之更動與潤飾,因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。 While the present invention has been described in its preferred embodiments, the present invention is not intended to limit the invention, and the present invention may be modified and modified without departing from the spirit and scope of the invention.
