近年來，由於顯示器在人們生活中的重要性日益增 加，除了使用電腦或網際網路外，電視機、手機、個人數 位助理(PDA)與數位相機等，均須透過顯示器控制來傳遞 訊息=相較於傳統映像管顯示器，新世代的平面顯示器具 有重量輕、體積小以及無輻射的優點，但其亮度、功率消 耗等問題仍有改善的空間。 。。在眾多新興的平面顯示器技術中，目前是以液晶顯示 器(^CD)為主流。由於液晶顯示器為非自發光的顯示器， 須藉由外加光源方式方可產生顯示功能，因此背光模組在 液晶顯示器中即扮演光源的角色，是為液晶顯示 零組件之一。 傳統的顯示器背光源中，大多採用冷陰極燈管⑴^^^ =照明平面顯示器。冷陰極螢光管因其使用壽命短、耗電 Μ ^大、且燈管中含有果金屬易對環境造成汙染，使其應用 7圍文到限制。而發光二極體(LED)為一種高效率之主動 發光源，具有低功率消耗、高亮度輸出以及體積小等優點， 故成為一種優良之光源。 5 M324224 睛參閱圖1，為習知背光模組丨0之立體示意圖，其主 要包括有一導光板Π以及複數個發光二極體12，該些發光 一極體12為此背光模組1 〇之光源。習知之背光模組1 〇之導 光板11為類似矩形結構，且導光板u之厚度與發光二極體 5 12厚度儘可能相同，以防止面板輝度的損耗與衰減。而背 光模組10之光源（發光二極體12)則設計成燈條（Light Bar) 形式排列在導光板Π的側邊，使光線由側邊進入導光板u 中 叙而S，發光二極體12與導光板11的距離越接近所 得到的背光模組輝度會越高。因此，如圖丨所示，發光二極 10體12貼附於導光板丨丨時，發光二極體12光線利用效率最 高，然而卻易造成發光二極體12進入導光板u之界面處或 界面處附近出現一段亮帶。 再者，目前平面顯示器的需求已日趨薄形化發展，習 知=光模組1 〇將發光二極體i2以燈條（Light Bar)形式排列 U在導光板11的側邊，必然會增加背光模組1〇的佔用空間以 放置發光二極體1 2。 因此，如何增加習知背光模組的輝度及均一性，並減 少背光模組的佔用體積，將是目前亟需解決之課題。 20【新型内容】 有鑑於此，本創作提供一種背光模組，包括··一導光 板以及-光源，該導光板包含：一出光面；一反射面，係 與該出光面對向設置，該反射面包含_曲面；以及至少〆 缺口 °又置於该導光板之一側邊，該缺口包含一第一平面 6 M324224 與一第二平面’其中該第一平面與該出光面連接，該第二 平面與該曲面連接；該光源容置該導光板之該缺口中。： 此，減少背光模組之光源佔據的體積，並增加 9 的輝度和均一性。 保、、且In recent years, due to the increasing importance of displays in people's lives, in addition to computers or the Internet, televisions, mobile phones, personal digital assistants (PDAs) and digital cameras, etc., must transmit messages through display controls. Compared with traditional image tube displays, the new generation of flat panel displays have the advantages of light weight, small size and no radiation, but there is still room for improvement in terms of brightness, power consumption and the like. . . Among the many emerging flat panel display technologies, liquid crystal displays (^CD) are currently the mainstream. Since the liquid crystal display is a non-self-illuminating display, the display function can be generated by applying an external light source. Therefore, the backlight module plays a role as a light source in the liquid crystal display, and is one of the liquid crystal display components. Most of the traditional display backlights use cold cathode lamps (1) ^^^ = illuminated flat panel displays. The cold cathode fluorescent tube has a short service life, consumes a large amount of electricity, and contains a fruit metal in the tube, which is easy to pollute the environment, so that it is limited to the application. The light-emitting diode (LED) is a high-efficiency active light source with low power consumption, high brightness output and small volume, which makes it an excellent light source. 5 M324224 The eye is a schematic view of a conventional backlight module 丨0, which mainly includes a light guide plate Π and a plurality of light-emitting diodes 12, and the light-emitting diodes 12 are used for the backlight module 1 light source. The light guide plate 11 of the conventional backlight module 1 has a rectangular structure, and the thickness of the light guide plate u is as equal as the thickness of the light emitting diode 52 to prevent loss and attenuation of the brightness of the panel. The light source (light-emitting diode 12) of the backlight module 10 is designed as a light bar arranged on the side of the light guide plate ,, so that the light enters the light guide plate u from the side, and the light-emitting diode The closer the distance between the body 12 and the light guide plate 11 is, the higher the brightness of the resulting backlight module will be. Therefore, as shown in FIG. ,, when the light-emitting diode 10 is attached to the light guide plate, the light-emitting diode 12 has the highest light utilization efficiency, but it is easy to cause the light-emitting diode 12 to enter the interface of the light guide plate u or A bright band appears near the interface. In addition, the demand for flat panel displays has become increasingly thinner. Conventionally, the optical module 1 〇 aligns the light-emitting diodes i2 in the form of a light bar (U) on the side of the light guide plate 11, which is bound to increase. The occupied space of the backlight module 1 以 is to place the light emitting diode 12 . Therefore, how to increase the brightness and uniformity of the conventional backlight module and reduce the occupied volume of the backlight module will be an urgent problem to be solved. 20 [New content] In view of this, the present invention provides a backlight module, comprising: a light guide plate and a light source, the light guide plate includes: a light exit surface; a reflective surface is disposed opposite to the light exiting surface, The reflective surface includes a _ curved surface; and at least the 〆 notch is further disposed on a side of the light guide plate, the notch includes a first plane 6 M324224 and a second plane ′, wherein the first plane is connected to the illuminating surface, the first The two planes are connected to the curved surface; the light source is received in the gap of the light guide plate. : This reduces the volume occupied by the light source of the backlight module and increases the brightness and uniformity of 9.

For the purpose of creating a preferred embodiment of the optical module 20, FIG. 3 is a cross-sectional view and a cross-sectional view of FIG. 2. The backlight module 2 of the present embodiment includes a light guide plate 2. And a plurality of light sources 23, the light guide plate 21 is an acrylic resin, and the light guide plate 21 of the embodiment has a light-emitting surface 23, a reflecting surface 25 and a notch 26. The reflecting surface and the light emitting surface are disposed in a direction of 5, and the reflecting surface comprises a curved surface. The notch 26 is disposed at a side of the light guiding plate 21. The light guiding plate of the embodiment Only a single side has a notch 26, and the notch % includes a first plane 27 and a second plane 28, the first plane 27 is connected to the light exit surface 23, and the second plane 28 is connected to the curved surface. Having a plurality of light emitting diodes 22, and in this embodiment The depth of the notch 26 is slightly larger than the height h of the light-emitting diode 22, so that the light-emitting diode 22 is completely accommodated in the notch 26 without additionally increasing the volume occupied by the entire moonlight module 20. The light-emitting diodes 22 are attached to the light guide plate 21 to reduce the light intensity loss. In the backlight module 2 of the embodiment, the reflective surface 25 of the light guide plate 21 can be selectively provided with dots (Fig. In the present embodiment, the reflecting surface 25 of the light guiding plate 21 can selectively form a dot by printing or use a sandblasting, etching, cutting or the like to make the reflecting surface 25 A rough surface is formed to scatter light introduced into the light guide plate 21.
