第1圖是顯示根據本發明第一具體實施例之用來發射光在兩 個方向的背光總成的示意圖。 參照第1圖，背光總成500包括光導引板300和亮度控制 構件400。光導引板300有一矩形平形六面體形狀且被放置在 第一顯示區域100和第二顯示區域200間。光導引板3〇〇包括 四個側表面’其包括光入射表面310，第一光發射表面32〇，和 第二光發射表面330。 特別地，第一和第二光發射表面320和330彼此面對且分別 地具有一矩形形狀。第一光發射表面320藉由四個包括光入射 表面310的側表面被連接至第二光發射表面330,光入射表面 310與第一和第二光發射表面320和330垂直。 光導引板300的光入射表面310接收從外部來的第一光305 12 1329763 玖、發明說明 。第一光305從一點光源，例如一光發射兩極真空管，或一線 性光源，例如CCFL，發射。發射第一光的光源已由相關數字 301指出。 在通過光入射表面310的過程中被改變為第二光315的第一 5光305具有不同於位於光源3〇1和光入射表面3ι〇間之空氣的 媒介。根據折射定律，第二光315被反射在光導引板3〇〇的内 側且從光導引板300發射至兩個方向。對應於第二光315之部 分的光從第-光表面320被發射至第一顯示區域1〇〇。從第一光 表面320發射至第一顯示區域⑽的光被定義為第三光奶。 1〇 對應於第二光315之剩餘部分的光從第二光發射表面330 被發射至第二顯示區域2〇〇。從第二光發射表面33()發射且被提 供至第二顯示區域2〇〇的光被定義為第四光335。 因此，供應第-光305至使用光導引板则的第—和第二顯 示區域100和200是可能的。 15 然而，只使用光導引板300控制在第-顯示區域的第一亮度 和在第二顯示區域的第二亮度是困難的。為了控制第一和第二 亮度’光導引板300必需被重新設計和重新製造。 在本發明中’亮度控制構件_控制在第—和第二顯示區域 1〇〇和200的第一和第二亮度。亮度控制構件働反射第四光 20 335 部分至第一顯不區域且傳輸第四光的剩餘部分至第二顯 不區域200 〇 亮度控制構件400有-包含聚乙烯對笨二曱酸醋片（ρΕΤ)樹

案之尺寸和配置的示意圖。 參照第2和第3圖，光導引板300包括數個放置在面向亮度 控制構件400之第二光發射表面330上的光反射墊331。光反射 墊331反射與第二光發射表面33〇相接觸之第二光315的一部 10分至第一光發射表面320。 光反射墊331以一矩陣構形被放置在第二光發射表面32〇上 。光反射墊331使用一絲網方法形成在第二光發射表面32〇上 。虽光反射墊331離光入射表面310愈遠時，光發射墊331的 平面尺寸變得愈大。改變光反射墊311的平面尺寸是為了藉由光 15反射塾331放置在第二光發射表面331上方而均句地維持第四 光335的反射量。 如第2圖所示’第—光發射表面咖平行於第二光發射表面 第4圖是赫根據本發明第二具財_之用來發射光在兩 20個方向的背光總成的示意圖。第5圖是顯示根據本發明之背光 總成’亮度在第-顯示區域和第二顯示區域的曲線圖。第6圖 是顯示根據本發明第三具體實施例之用來發射光在兩個方㈣ 背光總成的示意圖。 參照第4圖 第一光發射表面32G沒有平行於第二光發射表 14 1329763 玖、發明說明 面330。特定地，位於第—和第二光發射表面似和说間的厚 度在光入射表面310的地方是最厚的，且當第一和第二光發射 表面320 # 322變得離光入射表面31〇愈遠時，此厚度逐漸地 變薄。 5 參照第5圖’在第—顯示區域刚的第-亮度高於在第二顯 示區域的第二亮度。為了獲得第一亮度高於第二亮度的結果， 亮度控制構件400必需被控制為第四& 335的光反射率高於光 傳輸率。同樣地，為了獲得在第二顯示區域2〇〇的第二亮度高 於在第一顯示區域100的第一亮度，亮度控制構件400必需被 1〇控制為第四光335的光傳輸率高於光反射率。 如第6圖所7F，為了增進光導引板3〇〇的光學特性光學薄 片340可被放置在光導引板3〇〇的第一光發射表面32〇上。 “光學薄片340包括-漫射薄片⑷和—稜鏡薄片34[漫射 缚片342漫射第三光325和第四光奶從亮度控制構件柳反 15射的部分以提供一具有均勾亮度的光至第一顯示區域1〇〇。 放置在漫射薄片342上的稜鏡薄片344控制光發射穿過漫射 缚片342的方向以提供具有改良視覺角度的光。特定地稜鏡 薄片344包括一具有平板形狀的主體部34牦和用來增進亮度的 亮度增進部34仆，其被放置在面向第一光發射表面32〇的表面 2〇上。亮度增進部34朴連續地被放置在主體部344a上且從主體部 344a凸出以在橫截面上為_三角型。 第7圖是顯示根據本發明第四具體實施例之用來發射光在兩 個方向的背光總成的示意圖。 參照第7圖，背光總成1〇〇〇包括第一光導引板·，第二 15 1329763 玖、發明說明

I: Embodiment 3 Detailed Description of Embodiments of the Invention Fig. 1 is a view showing a backlight assembly for emitting light in two directions according to a first embodiment of the present invention. Referring to Fig. 1, a backlight assembly 500 includes a light guiding plate 300 and a brightness control member 400. The light guiding plate 300 has a rectangular flat hexahedral shape and is placed between the first display area 100 and the second display area 200. The light guiding plate 3 includes four side surfaces 'which include a light incident surface 310, a first light emitting surface 32A, and a second light emitting surface 330. Specifically, the first and second light emitting surfaces 320 and 330 face each other and have a rectangular shape, respectively. The first light emitting surface 320 is connected to the second light emitting surface 330 by four side surfaces including the light incident surface 310, which is perpendicular to the first and second light emitting surfaces 320 and 330. The light incident surface 310 of the light guiding plate 300 receives the first light 305 12 1329763 from the outside, and the description of the invention. The first light 305 is emitted from a point source, such as a light emitting two pole vacuum tube, or a linear source, such as a CCFL. The source that emits the first light has been indicated by the associated numeral 301. The first 5 light 305, which is changed to the second light 315 during the passage through the light incident surface 310, has a medium different from the air located between the light source 3〇1 and the light incident surface 3ι. According to the law of refraction, the second light 315 is reflected on the inner side of the light guiding plate 3A and emitted from the light guiding plate 300 to both directions. Light corresponding to a portion of the second light 315 is emitted from the first light surface 320 to the first display area 1〇〇. Light emitted from the first light surface 320 to the first display area (10) is defined as a third light milk. 1〇 Light corresponding to the remaining portion of the second light 315 is emitted from the second light emitting surface 330 to the second display area 2〇〇. Light emitted from the second light emitting surface 33() and supplied to the second display region 2A is defined as the fourth light 335. Therefore, it is possible to supply the first light 305 to the first and second display areas 100 and 200 using the light guiding plate. 15 However, it is difficult to control only the first brightness in the first display area and the second brightness in the second display area using only the light guiding plate 300. In order to control the first and second brightnesses, the light guide plate 300 must be redesigned and remanufactured. In the present invention, the 'brightness control member' controls the first and second brightnesses in the first and second display areas 1 and 200. The brightness control member 働 reflects the fourth light 20 335 portion to the first display region and transmits the remaining portion of the fourth light to the second display region 200. The brightness control member 400 has - containing polyethylene versus bismuth citrate sheet ( ΕΤ ΕΤ) a sheet shape or a flat plate shape of the resin. The brightness control member can be constructed to reflect the fourth light 33S by about 80 〇 /. The light transmits and transmits about 4% of the light of the fourth light 335 or 9763 squares, and the invention illuminates about 20% of the light of the fourth light 335 and transmits about 80% of the light of the fourth light 335. The degree of freedom control member 400 can be constructed to use a material for partially reflecting and transmitting light. 2 is a schematic view showing a light reflection pattern placed on the light guide plate of the backlight assembly shown in FIG. 1, and FIG. 3 is a schematic view showing the size and arrangement of the light reflection pattern shown in FIG. . Referring to Figures 2 and 3, the light guiding plate 300 includes a plurality of light reflecting pads 331 placed on the second light emitting surface 330 facing the brightness control member 400. The light reflecting pad 331 reflects a portion 10 of the second light 315 in contact with the second light emitting surface 33A to the first light emitting surface 320. The light reflecting pad 331 is placed on the second light emitting surface 32A in a matrix configuration. The light reflecting pad 331 is formed on the second light emitting surface 32A using a screen method. The farther the light reflecting pad 331 is from the light incident surface 310, the larger the planar size of the light emitting pad 331 becomes. The plane size of the light reflecting pad 311 is changed in order to uniformly maintain the amount of reflection of the fourth light 335 by the light 15 reflecting 塾331 placed over the second light emitting surface 331. As shown in Fig. 2, the first light emitting surface is parallel to the second light emitting surface. Fig. 4 is a schematic view showing the backlight assembly for emitting light in two directions according to the second invention of the present invention. Fig. 5 is a graph showing the brightness of the backlight assembly according to the present invention in the first display area and the second display area. Figure 6 is a schematic view showing the emission of light in two square (four) backlight assemblies in accordance with a third embodiment of the present invention. Referring to Fig. 4, the first light-emitting surface 32G is not parallel to the second light-emitting table 14 1329763 玖, the invention section 330. Specifically, the thickness between the first and second light emitting surfaces is the thickest at the light incident surface 310, and when the first and second light emitting surfaces 320 #322 become away from the light incident surface 31 The greater the distance, the thinner the thickness. 5 Referring to Fig. 5', the first brightness in the first display area is higher than the second brightness in the second display area. In order to obtain a result that the first brightness is higher than the second brightness, the brightness control member 400 must be controlled such that the light reflectance of the fourth & 335 is higher than the light transmission rate. Likewise, in order to obtain that the second brightness in the second display area 2 is higher than the first brightness in the first display area 100, the brightness control member 400 must be controlled to be higher than the fourth light 335. Light reflectivity. As shown in Fig. 6 of Fig. 6, in order to enhance the optical characteristics of the light guiding plate 3, the optical sheet 340 can be placed on the first light emitting surface 32A of the light guiding plate 3A. "The optical sheet 340 includes a diffusing sheet (4) and a sheet 34 (the diffusing tab 342 diffuses the third light 325 and the portion of the fourth light milk from the brightness control member to provide a uniform brightness. The light is directed to the first display area 1. The germanium sheet 344 placed on the diffusing sheet 342 controls the direction of light emission through the diffusing tab 342 to provide light having a modified viewing angle. A main body portion 34 having a flat plate shape and a brightness enhancement portion 34 for enhancing brightness are disposed on the surface 2A facing the first light emitting surface 32. The brightness enhancement portion 34 is continuously placed at The main body portion 344a protrudes from the main body portion 344a to be triangular in cross section.
