The pattern design on the dot microstructure can destroy the total reflection in the light guide. The light emitted by the light source enters the light guide plate from the light incident surface of the light guide plate. When the dot structure is reached, it will not be reflected but will be refracted. In this case, the reflective sheet attached to the light guide plate can be used for the reflective sheet.

請參閱第1(a)及1(b)圖,其為本發明第一實施例之示意圖。液晶顯示器的背光模組100具有發光單元110、導光板120、背板130及空氣間隙層140,其中導光板120具有複數個微結構121、入光面122、出光面123及底面124,而背板130具有背板本體131、反射材料132及周框133。 Please refer to Figures 1(a) and 1(b) for a first embodiment of the present invention. The backlight module 100 of the liquid crystal display has a light emitting unit 110, a light guide plate 120, a back plate 130 and an air gap layer 140. The light guide plate 120 has a plurality of microstructures 121, a light incident surface 122, a light exit surface 123 and a bottom surface 124, and the back surface The plate 130 has a back plate body 131, a reflective material 132, and a perimeter frame 133.
發光單元110被配置以提供光線給導光板120,而發光單元110所發射出的光線在經由導光板120和背板130的反射材料132而到達液晶顯示面板(未顯示),據以提供面光源給液晶顯示器。發光單元110可以是發光二極體(light-emitting diode,LED)、冷陰極螢光燈管(cold cathode fluorescent lamp,CCFL)或具有發光功能的元件,此外,發光單元110較佳可為發光條。 The light emitting unit 110 is configured to provide light to the light guide plate 120, and the light emitted by the light emitting unit 110 reaches the liquid crystal display panel (not shown) through the reflective material 132 of the light guide plate 120 and the back plate 130, thereby providing a surface light source. Give the LCD monitor. The light emitting unit 110 may be a light-emitting diode (LED), a cold cathode fluorescent lamp (CCFL) or an element having a light emitting function. Further, the light emitting unit 110 may preferably be a light emitting strip. .
導光板120被配置以用來引導發光單元110所發射的光線,發光單元110所發出的光線會先經由導光板120的入光面122進入導光板120中,部分的光線會因為反射原理而經由出光面123射出導光板120,但部分的光線會因為全反射原理而在導光板120中傳遞,而無法被引導出導光板120。為了解決此問題,複數個微結構121被配置於導光板120的底面124上,複數個微結構121具有可以破壞導光板120內全反射的圖案,換言之,發光單元110所發射的光線在導光板120中進入全反射後,如果光線被反射到複數個微結構121的其中之一時,微結構上的圖案會使 光線離開全反射的狀態而進行折射。此外,背光模組100的導光板120可以是壓克力導光板、玻璃導光板或其他材料的導光板。 The light guide plate 120 is configured to guide the light emitted by the light emitting unit 110. The light emitted by the light emitting unit 110 first enters the light guide plate 120 through the light incident surface 122 of the light guide plate 120, and part of the light is passed through the reflection principle. The light-emitting surface 123 emits the light guide plate 120, but part of the light is transmitted in the light guide plate 120 due to the principle of total reflection, and cannot be guided out of the light guide plate 120. In order to solve this problem, a plurality of microstructures 121 are disposed on the bottom surface 124 of the light guide plate 120. The plurality of microstructures 121 have a pattern that can completely reflect the total reflection in the light guide plate 120. In other words, the light emitted by the light emitting unit 110 is on the light guide plate. After entering total reflection in 120, if the light is reflected to one of the plurality of microstructures 121, the pattern on the microstructure will The light is refracted away from the state of total reflection. In addition, the light guide plate 120 of the backlight module 100 may be an acrylic light guide plate, a glass light guide plate or a light guide plate of other materials.
背板130被配置以承載發光單元110及導光板120,並提供反射的功能。若背光模組100具有其他光學層,則該些其他光學層亦可由背板130以固定於周框之方式或夾合之方式來承載,例如:擴散片、稜鏡片...等。背板130的背板本體131具有內表面131a及外表面131b,而內表面131a為一平面,周框133設置於背板本體131的外圍,並被配置以承載發光單元110、導光板120或/及其他光學層。背板130可以是玻璃背板(含強化玻璃)、金屬背板、壓克力背板或其他具有支撐效果之背板。此外,背板130亦可作為液晶顯示器的外殼,而背板本體131的內表面131a不會有凹槽或孔洞,為一完整的平面。周框133亦可被設計以使周框133和內表面131a相連接時形成弧面或非平面,而完全平坦的內表面131a原則上是與導光板120相對應。 The back plate 130 is configured to carry the light emitting unit 110 and the light guide plate 120 and provide a function of reflection. If the backlight module 100 has other optical layers, the other optical layers may be carried by the back plate 130 in a manner of being fixed to the peripheral frame or sandwiched, for example, a diffusion sheet, a cymbal sheet, or the like. The backplane body 131 of the backplane 130 has an inner surface 131a and an outer surface 131b, and the inner surface 131a is a plane. The peripheral frame 133 is disposed at a periphery of the backplane body 131 and configured to carry the light emitting unit 110, the light guide plate 120 or / and other optical layers. The backing plate 130 may be a glass backing plate (including tempered glass), a metal backing plate, an acrylic backing plate or other backing plate having a supporting effect. In addition, the back plate 130 can also serve as the outer casing of the liquid crystal display, and the inner surface 131a of the back plate body 131 does not have grooves or holes and is a complete plane. The peripheral frame 133 can also be designed to form a curved or non-planar surface when the peripheral frame 133 and the inner surface 131a are joined, and the completely flat inner surface 131a corresponds in principle to the light guide plate 120.
反射材料132形成於背板本體131的內表面131a上,以使背光模組100具有反射效果,當發光單元110所發出的光線經過導光板120的複數個微結構121而發生折射時,折射的光線會被傳遞到背板本體131的反射材料132,隨後光線會經由反射材料132而被反射回導光板120,最終經由出光面123而被傳遞出導光板120。反射材料132可以是銅、銀、金、鋁或其他具有反射性質的材料,亦可為上述材料之任意組合。此外,反射材料132可以藉由塗佈方式、電鍍方式、氣相沉積方式或其他習用方式而形成於內表面131a上。值得注意的是,背板本體131和反射材料132可以使用同一種具有反射性質的材料,換言之,背板本體131被形 成時即具有反射的效果。 The reflective material 132 is formed on the inner surface 131a of the back plate body 131, so that the backlight module 100 has a reflection effect. When the light emitted by the light emitting unit 110 is refracted by the plurality of microstructures 121 of the light guide plate 120, the refracting The light is transmitted to the reflective material 132 of the back plate body 131, and then the light is reflected back to the light guide plate 120 via the reflective material 132, and finally transmitted to the light guide plate 120 via the light exit surface 123. The reflective material 132 can be copper, silver, gold, aluminum or other material having reflective properties, and can be any combination of the above materials. Further, the reflective material 132 may be formed on the inner surface 131a by a coating method, a plating method, a vapor deposition method, or the like. It should be noted that the back plate body 131 and the reflective material 132 may use the same material having reflective properties, in other words, the back plate body 131 is shaped. It has the effect of reflection when it is formed.
在組合發光單元110、導光板120和背板130的過程中,導光板120會被固定於背板130的周框133上或被限制在一個範圍內,而導光板120和背板本體131內表面131a上的反射材料132之間會有一距離,進而形成一空氣間隙層140,由於空氣間隙層140的存在之故,導光板120和背板130不會互相接合。此外,除了用固定於周框的方式外,亦可用夾合的方式使導光板120於背光模組100中不會任意移動。 In the process of combining the light emitting unit 110, the light guide plate 120 and the back plate 130, the light guide plate 120 is fixed on the peripheral frame 133 of the back plate 130 or is limited to a range, and the light guide plate 120 and the back plate body 131 are inside. There is a distance between the reflective materials 132 on the surface 131a, thereby forming an air gap layer 140. Due to the presence of the air gap layer 140, the light guide plate 120 and the back plate 130 are not bonded to each other. In addition, in addition to the manner of being fixed to the peripheral frame, the light guide plate 120 may not be arbitrarily moved in the backlight module 100 by sandwiching.

The light guide plate 220 has a plurality of microstructures 221, a light-incident surface 222, a light-emitting surface 223 and a bottom surface 224, and the back plate 230 has a back plate body 231, a reflective material 232, and a perimeter frame 233. The back plate 230 is configured to carry the light emitting unit 210 and the light guide plate 220 , and the plurality of microstructures 221 are disposed on the bottom surface 224 of the light guide plate 220 .
本發明第二實施例中,反射材料232藉由塗佈方式、電鍍方式、氣相沉積方式或其他習用方式而至少部分覆蓋於背板本體的內表面上,形成複數個具有反射材料232的區域,該些複數個區域的相對位置或形狀可以依據需求而被設計。由於反射材料232並非全部覆蓋於背板本體的內表面上,故可以節省反射材料的使用量以控制成本,尤其是使用高價位的反射材料。 In the second embodiment of the present invention, the reflective material 232 is at least partially covered on the inner surface of the back plate body by a coating method, a plating method, a vapor deposition method or other conventional methods to form a plurality of regions having the reflective material 232. The relative positions or shapes of the plurality of regions can be designed according to requirements. Since the reflective material 232 does not entirely cover the inner surface of the backplane body, the amount of reflective material used can be saved to control cost, especially using high-priced reflective materials.
本發明第二實施例中,液晶顯示面板400被配置於背光模組200的導光板220的出光面223外側,而發光單元210所射出的光線會由導光板220的入光面222進入導光板220中,一部分的光線會經由反射、折 射而從出光面223被傳遞到液晶顯示面板400,另一部分符合導光板220中全反射條件的光線會在被傳遞到複數個微結構221時被折射出導光板220,進而被傳遞到背板本體231內表面上的反射材料232,在經由反射而進入導光板220中,並從出光面223被引導至液晶顯示面板400。 In the second embodiment of the present invention, the liquid crystal display panel 400 is disposed outside the light-emitting surface 223 of the light guide plate 220 of the backlight module 200, and the light emitted by the light-emitting unit 210 enters the light guide plate from the light-incident surface 222 of the light guide plate 220.
