Description

本考案はバックライトモジュール装置に関するものであり，特に，光源の光が導光板に入るライトフィールドの分布を変更するということを指す． The present invention relates to a backlight module device, and particularly refers to changing the distribution of the light field where light from the light source enters the light guide plate.

図1に示すように，従来から既知のバックライトモジュール１は導光板１１を含む．導光板１１は出光面１１１，反射面１１２，少なくとも一つの入射面１１３がある．反射板１２は導光板１１の反射面１１２の外表面に配置される．複数の光拡散薄片１３は導光板１１の出光面１１１の外表面に配置される．複数の集光薄片１４はさらに，光拡散薄片１３の別面に配置される．光拡散薄片１３及び集光薄片１４を相互に交錯，挿入するように配置してもよい．ランプ１５は導光板１１の入射面１１３の外表面に配置される．また，ランプの反射器１６は大きな面積で，ランプ１５を覆う． As shown in FIG. 1, a conventionally known backlight module 1 includes a light guide plate 11. The light guide plate 11 has a light exit surface 111, a reflection surface 112, and at least one incident surface 113. The reflecting plate 12 is disposed on the outer surface of the reflecting surface 112 of the light guide plate 11. The plurality of light diffusing slices 13 are disposed on the outer surface of the light exit surface 111 of the light guide plate 11. The plurality of concentrating flakes 14 are further arranged on another surface of the light diffusing flakes 13. The light diffusing flakes 13 and the light collecting flakes 14 may be arranged so as to cross each other and to be inserted. The lamp 15 is disposed on the outer surface of the incident surface 113 of the light guide plate 11. The reflector 16 of the lamp covers a lamp 15 with a large area.

導光板１１の材質はほぼ，光学級アクリル(acrylic)（PMMA）から作られるので，光源の透過射出に役立つ．また，反射面１１２に，多い導光点１１２１を設置する．それら導光点１１２１は光源との距離の遠近に応じて，小から大まで，又は疎から密まで分布するように形成される． The material of the light guide plate 11 is almost made of optical grade acrylic (PMMA), which is useful for light source transmission. In addition, many light guide points 1121 are installed on the reflection surface 112. These light guide points 1121 are formed so as to be distributed from small to large, or from sparse to dense, depending on the distance from the light source.

図2に示すように，ランプ１５に電力を供給したあとで，光が出てくる．光は入射面１１３から，導光板１１の内部に入る．導光板１１の中の光を伝送しているうちに，導光板１１の反射面１１２における導光点１１２１に反射されるので，その導きで，出光面１１１を経由して離れて，光が出てくる． As shown in FIG. 2, light is emitted after power is supplied to the lamp 15. Light enters the light guide plate 11 from the incident surface 113. While the light in the light guide plate 11 is transmitted, the light is reflected by the light guide point 1121 on the reflection surface 112 of the light guide plate 11. Come on.

でも，ランプ１５が平行のように，導光板１１の入射面１１３の外に配置されるので，それら光が導光板１１の内部に入るときに，光の入射角の大多数が導光板１１の全反射臨界角より小さいせいで，部分の光が導光板１１の反射面１１２の導光点１１２１を経由して反射できるが，大部分の光が水平のように前進しつづけて，ついに反入射面１１４までのロスが出てきて，光のエネルギーの損耗を招くと言う不都合があった． However, since the lamps 15 are arranged outside the incident surface 113 of the light guide plate 11 so as to be parallel, when the light enters the light guide plate 11, the majority of the incident angles of the light are that of the light guide plate 11. Because the light is smaller than the total reflection critical angle, part of the light can be reflected via the light guide point 1121 of the reflection surface 112 of the light guide plate 11, but most of the light continues to advance horizontally and finally is incident on the opposite side. There was an inconvenience that a loss up to the surface 114 occurred, leading to wear of light energy.

近年以来，液晶ディスプレイ（ＴＦＴ−ＬＣＤ）の応用が益々普及しているので，そのバックライトモジュール１の光源表現は日々に厳しく要求される．前掲の光のロスという不良も次第に重視され，本考案はこれを克服し、それにより，産業のレベルをアップグレードさせようとする考案である． Since the application of liquid crystal display (TFT-LCD) has become more and more popular since recent years, the light source expression of the backlight module 1 is strictly demanded every day. The above-mentioned defect of loss of light is also increasingly emphasized, and the present invention is an idea to overcome this and thereby upgrade the level of industry.

したがって，本考案の主な目的はバックライトモジュール装置を提供することにある．特に，光源の光が導光板に入るライトフィールドの分布を変更することにより，光源の光が導光板の反入射面に生じるロスを低降するという現象を生じるのを阻止しようとするものを指す． Therefore, the main purpose of the present invention is to provide a backlight module device. In particular, it refers to the one that tries to prevent the phenomenon that the light of the light source falls on the anti-incident surface of the light guide plate by changing the distribution of the light field that the light source enters the light guide plate. .

そんな目的を達成するために，本考案のバックライトモジュール装置は主に，バックライトモジュールのランプと導光板との間に，光のカップリングユニットを設置する．カップリングユニットは一つの受光面及び一つの出光面を具有する．受光面はランプの相隣箇所に設置される．出光面は導光板の入射面に対応する位置に設置される．それで，ランプの光を伝送して，導光板の中へ送る．光のカップリングユニットの受光面，出光面は少なくとも，一つの表面がランプの光の前進方向と，非垂直面の状態となる．つまり，本来，平行前進してあるランプの光が非垂直面状の受光面又は出光面に屈折されたことにより，光の平行前進方向を変更する．光が導光板に入ったあとで，導光板の出光面及び反射面の二つ方向へ前進する．そうすると，光源の光が導光板の反入射面に生じるロスを大幅に低降する． In order to achieve such a purpose, the backlight module device of the present invention mainly installs a light coupling unit between the lamp of the backlight module and the light guide plate. The coupling unit has one light receiving surface and one light emitting surface. The light-receiving surface is installed next to the lamp. The light exit surface is installed at a position corresponding to the entrance surface of the light guide plate. Therefore, the light from the lamp is transmitted and sent into the light guide plate. At least one of the light-receiving surface and light-emitting surface of the light coupling unit is in a state where the lamp advances and the surface is non-perpendicular. In other words, the parallel light advance direction is changed by refracting the light from the lamp that is originally traveling in parallel to the light receiving surface or light exit surface. After the light enters the light guide plate, it advances in two directions, the light exit surface and the reflection surface of the light guide plate. Then, the loss of light from the light source on the anti-incident surface of the light guide plate is greatly reduced.

本考案のもう一つ目的はバックライトモジュール装置を提供することにある．光のカップリングユニットの受光面，出光面は少なくとも，一つの表面がランプの光の前進方向と，非垂直面の状態となる．そんな非垂直面状態の設計変化は円曲面や単一凸曲面や単一凹曲面や単一凹凸曲面や複数連続の凸曲面や複数連続の凹曲面や複数連続の凹凸曲面や複数連続の間隔の凸曲面や複数連続の間隔の凹凸曲面や複数連続の等しくない弧度の凸曲面や複数連続の等しくない弧度の凹曲面や複数連続の等しくない弧度の凹凸曲面や複数連続間隔の等しくない弧度の凸曲面や複数連続間隔の等しくない弧度の凹曲面や局部凸曲面や局部凹曲面などを採用してもよい．前掲の円曲面の設計で，光を屈折したあとで，光の行進方向を変更し，光源の光が導光板に入るライトフィールドの分布を変更する Another object of the present invention is to provide a backlight module device. At least one of the light-receiving surface and light-emitting surface of the light coupling unit is in a state where the lamp advances and the surface is non-perpendicular. Such non-vertical surface design changes include circular curved surfaces, single convex curved surfaces, single concave curved surfaces, single concave curved surfaces, multiple continuous convex curved surfaces, multiple continuous concave curved surfaces, multiple continuous concave curved surfaces, and multiple continuous intervals. Convex curved surface, uneven curved surface with multiple consecutive intervals, convex curved surface with multiple consecutive unequal arc degrees, concave curved surface with multiple consecutive unequal arc degrees, convex / concave curved surface with multiple consecutive unequal arc degrees, convexity with multiple consecutive unequal arc degrees A curved surface, a concave curved surface with a plurality of consecutively spaced arcs, a local convex curved surface, or a local concave curved surface may be used. With the circular curved surface design described above, after the light is refracted, the direction of the light is changed, and the distribution of the light field where the light from the light source enters the light guide plate is changed.

本考案のもう一つの目的はバックライトモジュール装置を提供することにある．光のカップリングユニットの受光面，出光面は少なくとも，一つの表面がランプの光の前進方向と，非垂直面の状態となる．そんな非垂直面状態の設計変化は鋸歯面状や凹鋸歯面や凸鋸歯面や連続性鋸歯面や非対等斜辺長さの凹鋸歯面や非対等斜辺長さの凸鋸歯面や異なる挟み角度の連続性鋸歯面や異なる高さ(深さ)の連続性鋸歯面などを採用してもよい．前掲の鋸歯面の設計で，光を屈折したあとで，光の行進方向を変更し，光源の光が導光板に入るライトフィールドの分布を変更する． Another object of the present invention is to provide a backlight module device. At least one of the light-receiving surface and light-emitting surface of the light coupling unit is in a state where the lamp advances and the surface is non-perpendicular. Such non-vertical surface design changes include sawtooth surfaces, concave sawtooth surfaces, convex sawtooth surfaces, continuous sawtooth surfaces, concave sawtooth surfaces with non-equal oblique side lengths, convex sawtooth surfaces with non-equal oblique side lengths, and different pinching angles. A continuous sawtooth surface or a continuous sawtooth surface of different height (depth) may be used. In the design of the sawtooth surface described above, after the light is refracted, the light marching direction is changed, and the distribution of the light field where the light from the light source enters the light guide plate is changed.

本考案のもう一つの目的はバックライトモジュール装置を提供することにある．光のカップリングユニットの受光面，出光面は少なくとも，一つの表面がランプの光の前進方向と，非垂直面の状態となる．そんな非垂直面状態の設計変化は同時に，鋸歯面及び円曲面を形成してもよい．そんな形体の変化は単一の凸鋸歯面と凸曲面の組合や単一の凸鋸歯面と凹曲面の組合や単一の凹鋸歯面と凹曲面の組合や複数の凸鋸歯面と凸曲面の組合や複数の凸鋸歯面と凹曲面の組合や複数の凹鋸歯面と凹曲面の組合を採用してもよい．上述のように，同時に採用した鋸歯面及び円曲面の設計で，光を屈折したあとで，光の行進方向を変更し，光源の光が導光板に入るライトフィールドの分布を変更する．
本考案の目的，特徴および効果などをご了解
なさるために，以下，さらに具体的な実施例に図面をあわせて詳しく説明してみよう。 Another object of the present invention is to provide a backlight module device. At least one of the light-receiving surface and light-emitting surface of the light coupling unit is in a state where the lamp advances and the surface is non-perpendicular. Such a design change in the non-vertical surface state may simultaneously form a sawtooth surface and a circular curved surface. Such a shape change is a combination of a single convex sawtooth surface and a convex curved surface, a combination of a single convex sawtooth surface and a concave curved surface, a combination of a single concave sawtooth surface and a concave curved surface, or a plurality of convex sawtooth surfaces and convex curved surfaces. A combination, a combination of a plurality of convex sawtooth surfaces and a concave curved surface, or a combination of a plurality of concave sawtooth surfaces and a concave curved surface may be employed. As described above, the design of the sawtooth and circular curved surfaces adopted at the same time changes the light field distribution after the light is refracted, and changes the distribution of the light field where the light from the light source enters the light guide plate.
In order to understand the purpose, features, and effects of the present invention, a more detailed description will be given below with reference to specific examples.

そうすると，ランプの光源がそれに屈折されたあとで，光源の光が導光板に入るライトフィールド(light field)の分布を変更するので，光源の光が導光板の反入射面に生じるロスを低降し，光源の利用効率を向上させる． Then, after the light source of the lamp is refracted, the distribution of the light field into which the light source enters the light guide plate is changed, so that the loss of light caused by the light source on the anti-incident surface of the light guide plate is reduced. And improve the light source usage efficiency.

まずは図３を御覧下さい．それは本考案のバックライトモジュール装置である．そんなバックライトモジュール２は少なくとも，一枚の導光板２１を含む．導光板２１は出光面２１１，出光面２１１の対応位置における反射面２１２，少なくとも一つの入射面２１３，入射面２１３の対応位置における反入射面２１４を具有する．反射面２１２には，細密に分布した沢山な導光点２１２１がある．反射板２２は導光板２１の反射面２１２の外表面に配置される．数量が等しくない拡散薄片２３及び集光薄片２４は導光板２１の出光面２１１の外表面に配置される．ランプ２５は導光板２１の入射面２１３の外表面に配置される．ランプの反射器２６は大きな面積で，ランプ２５を覆う．また，ランプ２５と導光板２１の入射面２１３との間に，光のカップリングユニット２７を設置する． Please see Figure 3 first. It is the backlight module device of the present invention. Such a backlight module 2 includes at least one light guide plate 21. The light guide plate 21 includes a light exit surface 211, a reflective surface 212 at a corresponding position of the light exit surface 211, and an anti-incident surface 214 at a corresponding position of at least one incident surface 213 and an incident surface 213. The reflecting surface 212 has many light guide points 2121 that are finely distributed. The reflection plate 22 is disposed on the outer surface of the reflection surface 212 of the light guide plate 21. The diffusing thin pieces 23 and the light collecting thin pieces 24 having the same quantity are arranged on the outer surface of the light exit surface 211 of the light guide plate 21. The lamp 25 is disposed on the outer surface of the incident surface 213 of the light guide plate 21. The lamp reflector 26 covers a large area and covers the lamp 25. Further, a light coupling unit 27 is installed between the lamp 25 and the incident surface 213 of the light guide plate 21.

光のカップリングユニット２７は光の優れた透過性を持つ材質で作られ，受光面２７１，出光面２７２がある．受光面２７１はランプ２５の位置に隣接する．出光面２７２は導光板２１の入射面２１３に隣接する．また，受光面２７１又は出光面２７２のいずれは少なくとも，一つの表面がランプ２５の光行進方向と，非垂直面状態となる． The light coupling unit 27 is made of a material having excellent light transmission, and has a light receiving surface 271 and a light emitting surface 272. The light receiving surface 271 is adjacent to the position of the lamp 25. The light exit surface 272 is adjacent to the incident surface 213 of the light guide plate 21. In addition, at least one of the light receiving surface 271 and the light emitting surface 272 is in a non-perpendicular surface state with respect to the light marching direction of the lamp 25.

図4を御覧下さい．光のカップリングユニット２７の受光面２７１又は出光面２７２のいずれは光行進方向と，非垂直面状態となる．円曲面状を採用すれば，図4−１乃至図4−17など変化がある．それらは順序に，単一凸曲面や単一凹曲面や単一凹凸曲面や複数連続の凸曲面や複数連続の凹曲面や複数連続の凹凸曲面や複数連続の間隔の凸曲面や複数連続の間隔の凹凸曲面や複数連続の等しくない弧度の凸曲面や複数連続の等しくない弧度の凹曲面や複数連続の等しくない弧度の凹凸曲面や複数連続間隔の等しくない弧度の凸曲面や複数連続間隔の等しくない弧度の凹曲面や局部凸曲面や局部凹曲面など例が挙げられる． See Figure 4. Either the light-receiving surface 271 or the light-emitting surface 272 of the light coupling unit 27 is in a light vertical direction and a non-vertical surface state. If a circular curved surface is adopted, there will be changes such as in Fig. 4-1 to Fig. 4-17. They are, in order, single convex surface, single concave surface, single concave surface, multiple continuous convex surface, multiple continuous concave surface, multiple continuous concave surface, multiple continuous convex surface, multiple continuous space Convex curved surface, Convex curved surface of multiple consecutive unequal arc degrees, Convex curved surface of multiple continuous unequal arc degrees, Convex curved surface of multiple consecutive unequal arc degrees, Convex curved surface of multiple consecutive unequal arc degrees, Equal multiple continuous intervals Examples include concave surfaces with no arc, local convex surfaces, and local concave surfaces.

光のカップリングユニット２７の受光面２７１又は出光面２７２のいずれは光行進方向と，非垂直面状態となる．鋸歯面状を採用すれば，図５−１乃至図５−８など形体変化がある．それらは順序に，凹鋸歯面や凸鋸歯面や連続性鋸歯面や非対等斜辺長さの凹鋸歯面や非対等斜辺長さの凸鋸歯面や異なる挟み角度の連続性鋸歯面や異なる高さ(深さ)の連続性鋸歯面など例が挙げられる． Either the light-receiving surface 271 or the light-emitting surface 272 of the light coupling unit 27 is in a light vertical direction and a non-vertical surface state. If the sawtooth surface shape is adopted, there will be changes in the shape as shown in Figs. 5-1 to 5-8. They are, in order, concave sawtooth surface, convex sawtooth surface, continuous sawtooth surface, concave sawtooth surface with non-equal oblique side length, convex sawtooth surface with non-equal oblique side length, continuous sawtooth surface with different sandwiching angles and different heights. Examples include (depth) continuous sawtooth surfaces.

光のカップリングユニット２７の受光面２７１又は出光面２７２のいずれは光行進方向と，非垂直面状態となる．同時に鋸歯面状と円曲面の組合を採用すれば，図６−１乃至図６−８など形体変化がある．それらは順序に，単一の凸鋸歯面と凸曲面の組合や単一の凸鋸歯面と凹曲面の組合や単一の凹鋸歯面と凹曲面の組合や複数の凸鋸歯面と凸曲面の組合や複数の凸鋸歯面と凹曲面の組合や複数の凹鋸歯面と凹曲面の組合など例が挙げられる． Either the light-receiving surface 271 or the light-emitting surface 272 of the light coupling unit 27 is in a light vertical direction and a non-vertical surface state. If a combination of serrated surface and circular curved surface is adopted at the same time, there will be changes in the shape such as in Fig. 6-1 to Fig. 6-8. They consist of a combination of a single convex sawtooth surface and a convex curved surface, a combination of a single convex sawtooth surface and a concave curved surface, a combination of a single concave sawtooth surface and a concave curved surface, or a plurality of convex sawtooth surfaces and convex curved surfaces. Examples include combinations, combinations of multiple convex sawtooth surfaces and concave curved surfaces, and combinations of multiple concave sawtooth surfaces and concave curved surfaces.

図7を御覧下さい．光のカップリングユニット２７の受光面２７１が非垂直面状となる場合に（ただ，図４−３の表示を御参照），次の作用がある．ランプ２５の光が受光面２７１に入射したあとで，光が屈折されて，光のカップリングユニット２７の内部へ行進し，出光面２７２より離れる．さらに，導光板２１の入射面２１３を経て，導光板２１の内部に入射してある．そのときに，光のカップリングユニット２７から離れる光はもう平行の方向のように，導光板２１に入射しなかった．逆に，導光板２１の出光面２１１及び反射面２１２の二つ方向へ向かって前進し，導光板２１の内部に入る．その結果，図８に示すように，導光板２１の入射光のライトフィールドの分布を変更するので，光源の光が導光板２１の反入射面２１４に生じる局部ロスを大幅に低降し，光源の利用効率を向上させる． See Figure 7. When the light receiving surface 271 of the light coupling unit 27 has a non-vertical surface shape (just refer to the display in FIG. 4-3), the following effects are obtained. After the light from the lamp 25 is incident on the light receiving surface 271, the light is refracted, marches into the light coupling unit 27, and leaves the light emitting surface 272. Further, the light enters the light guide plate 21 through the incident surface 213 of the light guide plate 21. At that time, the light leaving the light coupling unit 27 was no longer incident on the light guide plate 21 in the parallel direction. On the contrary, the light guide plate 21 moves forward in the two directions of the light exit surface 211 and the reflection surface 212 and enters the light guide plate 21. As a result, as shown in FIG. 8, since the distribution of the light field of the incident light on the light guide plate 21 is changed, the local loss caused by the light from the light source on the anti-incident surface 214 of the light guide plate 21 is greatly reduced. Improve the usage efficiency of.

図９を御覧下さい．光のカップリングユニット２７の出光面２７２が非垂直面状となる場合に（ただ，図４−３の表示を御参照），次の作用がある．ランプ２５の光が平行方向に沿って，光のカップリングユニット２７の中で行進してある．どこるが，出光面２７２を経て射出して離れるときに，出光面２７２が非垂直面状となるだから，光は屈折されて，導光板２１の出光面２１１及び反射面２１２の二つ方向へ向かって前進し，導光板２１の内部に入る．それも，導光板２１の入射光のライトフィールドの分布を変更するので，光源の光が導光板２１の反入射面２１４に生じる局部ロスを大幅に低降し，光源の利用効率を向上させる． Please refer to FIG. When the light exit surface 272 of the light coupling unit 27 has a non-vertical surface shape (just refer to the display in FIG. 4-3), the following effects are obtained. The light of the lamp 25 is marching in the light coupling unit 27 along the parallel direction. However, when the light exits through the light exit surface 272 and leaves, the light exit surface 272 becomes a non-vertical surface, so that the light is refracted and travels in the two directions of the light exit surface 211 and the reflection surface 212 of the light guide plate 21. It moves forward and enters the light guide plate 21. It also changes the light field distribution of the incident light on the light guide plate 21, so that the local loss caused by the light from the light source on the anti-incident surface 214 of the light guide plate 21 is greatly reduced, and the light source utilization efficiency is improved.

本考案を応用する場合に，図10に示すようになる．光のカップリングユニット２７はランプ２５と導光板２１との間に設置される．ランプの反射器２６は同時に，ランプ２５，光のカップリングユニット２７，導光板２１の三者を一緒に取り付けて，応用の実施目的を遂げる．導光板２１は矩形の形体を採用する以外，図11のような楔形を採用することもできる． Figure 10 shows the application of the present invention. The light coupling unit 27 is installed between the lamp 25 and the light guide plate 21. At the same time, the lamp reflector 26 attaches the lamp 25, the light coupling unit 27, and the light guide plate 21 together to achieve the application purpose. The light guide plate 21 may be a wedge shape as shown in FIG. 11 in addition to a rectangular shape.

要するに，本考案は導光板２１の本来設計を変更しなくても，導光板２１に入る光源の入射光のライトフィールドの分布を変更することができ，光源の光を導光板２１の出光面２１１及び反射面２１２の二つの方向へ向かうように前進させるので，光源の光が導光板２１の反入射面２１４に生じるロスを低降し，光源の利用効率を向上させる． In short, the present invention can change the distribution of the light field of the incident light of the light source entering the light guide plate 21 without changing the original design of the light guide plate 21, and the light from the light source can be changed to the light exit surface 211 of the light guide plate 21. Further, since the light source is moved forward in two directions, the loss of the light from the light source on the anti-incident surface 214 of the light guide plate 21 is lowered, and the light source utilization efficiency is improved.
