Description

本発明は、機械的強度を高めることができ、また、光源の光漏れを防止するとともに、内部への異物の流入を防止することができる光源装置及び該光源装置を備える表示装置に関する。   The present invention relates to a light source device that can increase mechanical strength, prevent light leakage of a light source, and prevent foreign matter from flowing into the inside, and a display device including the light source device.

近年、様々な表示装置が実用化されているが、表示装置の一種である液晶表示装置は、小型、薄型、低消費電力を特徴とし、近年ではその表示品位の向上により、従来のＣＲＴに替わるディスプレイとして普及しつつある。液晶表示装置は、自己発光型のデバイスとは異なり、液晶パネルの背面に光源装置（バックライト装置）を配置する必要がある。   In recent years, various display devices have been put into practical use. A liquid crystal display device, which is a type of display device, is characterized by its small size, thinness, and low power consumption. In recent years, the display quality has been improved, replacing the conventional CRT. It is becoming popular as a display. Unlike a self-luminous device, a liquid crystal display device requires a light source device (backlight device) to be disposed on the back surface of a liquid crystal panel.

液晶表示装置に用いられるバックライト装置は、図６に示すように、ランプクリップ１０２の係止部１０２ａをバックライトシャーシである板材１００に設けた貫通孔１００ａに挿入することによって、ランプクリップ１０２を板材１００に係止し、ランプクリップ１０２の把持部１０２ｂに冷陰極線放電管（ＣＣＦＬ）１０３を把持している（例えば、特許文献１参照。）。   As shown in FIG. 6, the backlight device used in the liquid crystal display device inserts the locking portion 102 a of the lamp clip 102 into the through hole 100 a provided in the plate material 100 that is the backlight chassis, so that the lamp clip 102 is inserted. The cold cathode ray discharge tube (CCFL) 103 is held by the holding member 102b of the lamp clip 102 (see, for example, Patent Document 1).

しかしながら、発光管１０３の光が貫通孔１００ａを通じて板材１００の裏面側に漏れるという問題があった。そこで、図７に示すように、板材１００の裏面側から不織布１１０を貫通孔１００ａに貼付することによって、光漏れを防止していた。
特開２００６−３０９３６号公報 However, there is a problem that light from the arc tube 103 leaks to the back side of the plate member 100 through the through hole 100a. Then, as shown in FIG. 7, the light leakage was prevented by sticking the nonwoven fabric 110 to the through-hole 100a from the back surface side of the board | plate material 100. As shown in FIG.
JP 2006-30936 A

しかしながら、板材１００は、一般にアルミニウムなどの再利用可能な金属製であり、不織布１１０を板材１００に貼付した場合、板材１００及びランプクリップ１０２を再利用する場合には、先ず不織布１１０を板材１００から取り除く必要がある。ところで、不織布１１０には接着力がないので接着剤を用いて不織布１１０を板材１００に貼付することから、不織布１１０を取り除く際に接着剤が板材１００に残存する虞があった。したがって、接着剤が残存した場合には金属の純度が低下し、板材１００の再利用性が悪化するという問題があった。   However, the sheet material 100 is generally made of a reusable metal such as aluminum. When the nonwoven fabric 110 is pasted on the sheet material 100, when the sheet material 100 and the lamp clip 102 are reused, the nonwoven material 110 is first removed from the sheet material 100. It needs to be removed. By the way, since the non-woven fabric 110 has no adhesive force, the non-woven fabric 110 is affixed to the plate material 100 using an adhesive, and therefore, the adhesive may remain on the plate material 100 when the non-woven fabric 110 is removed. Therefore, when the adhesive remains, there is a problem that the purity of the metal is lowered and the reusability of the plate member 100 is deteriorated.

また、経年変化によって接着剤の接着力が低下して不織布１１０が板材１００から剥離する虞があり、剥離した場合は、光漏れが発生するとともに、異物がバックライト装置の内部に侵入するという問題があった。   In addition, the adhesive strength of the adhesive may decrease due to secular change, and the nonwoven fabric 110 may be peeled off from the plate material 100. If peeled off, light leakage may occur and foreign matter may enter the backlight device. was there.

さらに、液晶表示装置は大画面化が容易であることから、画面サイズの大型化に伴って、それに対応してバックライト装置を大きくする必要がある。バックライト装置が大きくなれば、剛性を高めるために板材１００の厚みを厚くする必要があるため、重量が増大してしまい、ユーザが気軽に液晶表示装置を持ち運ぶことが困難となる。   Furthermore, since the liquid crystal display device can be easily enlarged, it is necessary to enlarge the backlight device corresponding to the increase in the screen size. If the backlight device becomes large, the thickness of the plate member 100 needs to be increased in order to increase the rigidity, so that the weight increases, and it becomes difficult for the user to easily carry the liquid crystal display device.

本発明は斯かる事情に鑑みてなされたものであり、貫通孔が形成された第１板材と、ハニカム構造の補強部材と、第２板材とを積層配置し、ランプクリップが第１板材に形成された貫通孔に挿入されることで第１板材に係止され、ランプクリップの係止領域を取り囲むように第１板材に孔群を設け、ランプクリップが係止された状態でその係止領域の第１板材を分断できる構成とすることにより、板材の厚みを単に厚くした場合と比較して、重量が軽量で、かつ機械的強度が高く、さらに、外部への光漏れ及び内部への異物の流入を防止し、加えて、第１板材からランプクリップを容易に除去して、第１板材をリサイクル資源とすることができる光源装置及び該光源装置を備える表示装置の提供を目的とする。 The present invention has been made in view of such circumstances, and a first plate member in which a through hole is formed, a reinforcing member having a honeycomb structure, and a second plate member are laminated and a lamp clip is formed on the first plate member. The hole is formed in the first plate member so as to surround the locking region of the lamp clip by being inserted into the formed through hole, and the locking region is held in a state where the lamp clip is locked. The first plate material can be divided so that the weight of the plate material is lighter and the mechanical strength is higher than when the thickness of the plate material is simply increased, and light leakage to the outside and foreign matter to the inside are achieved. In addition, an object of the present invention is to provide a light source device that can easily remove the lamp clip from the first plate material and use the first plate material as a recycled resource, and a display device including the light source device.

本発明に係る光源装置は、発光管がランプクリップに支持される光源装置において、貫通孔が形成された第１板材と、ハニカム構造の補強部材と、第２板材とが積層配置され、前記ランプクリップは、前記貫通孔に挿入されることで前記第１板材に係止され、該第１板材が、前記ランプクリップの係止領域を取り囲む孔群を備え、押圧によって、前記ランプクリップが係止された状態で前記係止領域の第１板材を分断可能にしてあることを特徴とする。 In the light source device according to the present invention, in the light source device in which the arc tube is supported by a lamp clip, a first plate member in which a through hole is formed, a reinforcing member having a honeycomb structure, and a second plate member are stacked and arranged. clip, the locked to the first plate member by being inserted into the through hole, said first plate member is provided with a hole group encircling the locking region of the lamp clip, the pressing, the lamp clips engaging In this state, the first plate member in the locking region can be divided.

本発明にあっては、貫通孔が形成された第１板材と、ハニカム構造の補強部材と、第２板材とを積層配置する。つまり、第１板材と第２板材との間隙にハニカム構造の補強部材を設ける。そして、ランプクリップを第１板材に形成された貫通孔に挿入することで第１板材に係止する。ハニカム構造は、軽量かつ高剛性であることから、板材の厚みを単純に厚くした場合と比較して、光源装置の重量を増大させることなく、機械的強度を高めることができる。また、発光管から出射された光のうち、第１板材の貫通孔を通じて第１板材の裏面側に漏れた漏光は、第２板材の存在によって光源装置の外部への導光を防止することができる。さらに、光源装置の内部への光の流入及び異物の流入を防止することができる。加えて、ランプクリップの係止領域を取り囲むように第１板材に孔群を設ける。この孔群を設けることによって、ランプクリップが係止された状態でその係止領域の第１板材を押圧により分断して除去することができる。 In the present invention, the first plate member in which the through holes are formed, the reinforcing member having the honeycomb structure, and the second plate member are laminated. That is, a reinforcing member having a honeycomb structure is provided in the gap between the first plate member and the second plate member. And a lamp clip is latched to the 1st board | plate material by inserting in the through-hole formed in the 1st board | plate material. Since the honeycomb structure is light and highly rigid, the mechanical strength can be increased without increasing the weight of the light source device as compared with the case where the thickness of the plate material is simply increased. In addition, light leaking from the arc tube to the back side of the first plate through the through hole of the first plate can prevent light from being guided to the outside of the light source device due to the presence of the second plate. it can. Furthermore, the inflow of light and the inflow of foreign matter into the light source device can be prevented. In addition , a hole group is provided in the first plate so as to surround the locking region of the lamp clip. By providing the hole group, the first plate member in the locking region can be cut and removed by pressing while the lamp clip is locked.

本発明に係る表示装置は、表示パネルと、該表示パネルの背面に上述した発明の光源装置とを備えることを特徴とする。 Display device according to the present invention is characterized by comprising a display panel, and inventions of the light source device described above on the back of the display panel.

本発明にあっては、上述したような光源装置を表示パネルの背面側に配置することで、重量を増大させることなく、大画面化を行なうことができ、また、光源装置の外部への導光、並びに、光源装置の内部への光の流入及び異物の流入を防止することができ、加えて、ランプクリップが係止された状態でその係止領域の第１板材を押圧により分断して除去することができる。 In the present invention, by arranging the light source device as described above on the back side of the display panel, it is possible to enlarge the screen without increasing the weight, and to introduce the light source device to the outside. Inflow of light and inflow of light and foreign matter into the light source device can be prevented, and in addition, the first plate member in the locking region is divided by pressing in a state where the lamp clip is locked. Ru can be removed.

本発明によれば、貫通孔が形成された第１板材と、ハニカム構造の補強部材と、第２板材とを積層配置する構成としたので、板材の厚みを単純に厚くした場合と比較して、光源装置の重量を増大させることなく、機械的強度を高めることができる。また、外部への光漏れ及び内部への異物の流入を防止することができる。そのため、製品としての品質を向上することができるとともに、異物の流入による装置寿命の短縮を防止することができる。加えて、ランプクリップの係止領域を取り囲むように第１板材に孔群を設け、ランプクリップが係止された状態でその係止領域の第１板材を分断できる構成としたので、第１板材からランプクリップを容易に除去することができる。したがって、第１板材をリサイクル資源とすることができる。 According to the present invention, since the first plate member in which the through holes are formed, the reinforcing member having the honeycomb structure, and the second plate member are stacked, the thickness of the plate member is simply increased. The mechanical strength can be increased without increasing the weight of the light source device. In addition, light leakage to the outside and inflow of foreign matter to the inside can be prevented. Therefore, quality as a product can be improved, and shortening of the device life due to inflow of foreign matter can be prevented. In addition , a hole group is provided in the first plate member so as to surround the locking region of the lamp clip, and the first plate member in the locking region can be divided in a state where the lamp clip is locked. The lamp clip can be easily removed from. Therefore, the first plate material can be used as a recycled resource.

本発明によれば、上述したような光源装置を表示パネルの背面側に配置することで、重量を増大させることなく、大画面化を行なうことができる。したがって、大画面の表示装置をユーザが気軽に持ち運ぶことができる。また、光源装置の外部への導光、並びに光源装置の内部への光の流入及び異物の流入を防止することができ、第１板材をリサイクル資源とすることができる等、優れた効果を奏する。 According to the present invention, by arranging the light source device as described above on the back side of the display panel, it is possible to enlarge the screen without increasing the weight. Therefore, the user can easily carry a large-screen display device . In addition, the light guide to the outside of the light source device, the inflow of light and the inflow of foreign matter to the inside of the light source device can be prevented, and the first plate material can be used as a recycled resource. .

以下、本発明をその実施の形態を示す図面に基づいて詳述する。   Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments thereof.

図１は本発明に係る表示装置である液晶表示装置の構成を示す側断面図、図２は本発明に係る光源装置としてのバックライト装置の構成を示す分解斜視図である。なお、図２においては、構成要素の一部（例えば反射シート１１など）を省略することによって本発明の特徴をわかり易くしている。
本発明に係る表示装置である液晶表示装置は、液晶パネル２と、液晶パネル２の背面に光源装置としてのバックライト装置１とを備える。 FIG. 1 is a side sectional view showing a configuration of a liquid crystal display device which is a display device according to the present invention, and FIG. 2 is an exploded perspective view showing a configuration of a backlight device as a light source device according to the present invention. In FIG. 2, the features of the present invention are easily understood by omitting some of the constituent elements (for example, the reflection sheet 11).
A liquid crystal display device which is a display device according to the present invention includes a liquid crystal panel 2 and a backlight device 1 as a light source device on the back surface of the liquid crystal panel 2.

液晶パネル２は、一対の透明板２１，２２が対向配置され、透明板２１，２２の周辺部をシール材などで封止することによって生じた間隙に液晶物質２０が充填された構成をしている。もちろん、球状又は柱状のスペーサを用いてギャップを精度良く保持することが好ましい。一方の透明板２１にはマトリックス状に配置されたＩＴＯ、ＮＥＳＡなどの透明性の画素電極と、画素電極への電荷の供給を制御するためのＴＦＴとが形成されており、他方の透明板２２にはコモン電極と呼ばれる透明性の共通電極が形成されている。ＴＦＴのゲート及びソースは、それぞれゲートドライバ及びソースドライバの各出力段に接続されている。   The liquid crystal panel 2 has a configuration in which a pair of transparent plates 21 and 22 are arranged to face each other, and a liquid crystal substance 20 is filled in a gap formed by sealing the peripheral portion of the transparent plates 21 and 22 with a sealing material or the like. Yes. Of course, it is preferable to use a spherical or columnar spacer to hold the gap with high accuracy. One transparent plate 21 is formed with a transparent pixel electrode such as ITO or NESA arranged in a matrix and a TFT for controlling charge supply to the pixel electrode, and the other transparent plate 22 is formed. A transparent common electrode called a common electrode is formed in the. The gate and source of the TFT are connected to the output stages of the gate driver and source driver, respectively.

透明板２１，２２の表面には、相互の偏光軸方向が直交した２枚の偏光板２３，２４がそれぞれ貼付されており、ゲートドライバから入力されたゲート信号によって各画素電極のオン／オフが制御され、ソースドライバから入力されたデータ信号をオン期間に各画素電極へ印加することによって、画素電極に印加された電圧と対向電極に印加された電圧との電圧差に基づいて、液晶物質２０の光透過率を制御する。   Two polarizing plates 23 and 24 whose polarization axes are orthogonal to each other are attached to the surfaces of the transparent plates 21 and 22, respectively, and each pixel electrode is turned on / off by a gate signal input from a gate driver. A liquid crystal substance 20 is controlled based on the voltage difference between the voltage applied to the pixel electrode and the voltage applied to the counter electrode by applying a controlled data signal input from the source driver to each pixel electrode during the ON period. To control the light transmittance.

バックライト装置１は、第１板材１０の内側面に反射シート１１が配置されている。反射シート１１は、例えば、アルミニウムなどの光反射性材料からなり、後述のＣＣＦＬ１３からの出射光を前面に反射させるようにしてある。   In the backlight device 1, the reflection sheet 11 is disposed on the inner surface of the first plate member 10. The reflection sheet 11 is made of, for example, a light reflective material such as aluminum, and reflects outgoing light from a CCFL 13 described later to the front surface.

第１板材１０には、複数の貫通孔１０ａが形成されており、この貫通孔１０ａにランプクリップ１２の係止部１２ａが挿入され、ランプクリップ１２が第１板材１０に固定されている。本例では、反射シート１１の上側からランプクリップ１２を挿入することから、反射シート１１にも、貫通孔１０ａと重なる位置に貫通孔が設けられている。   A plurality of through holes 10 a are formed in the first plate member 10, and a locking portion 12 a of the lamp clip 12 is inserted into the through hole 10 a, and the lamp clip 12 is fixed to the first plate member 10. In this example, since the lamp clip 12 is inserted from the upper side of the reflection sheet 11, the reflection sheet 11 is also provided with a through hole at a position overlapping the through hole 10a.

ランプクリップ１２は、把持部１２ｂにてＣＣＦＬ１３の直管部分を把持する。また、ランプクリップ１２には、円錐状の柱部１２ｃが設けられており、この柱部１２ｃにて、拡散板１７及びプリズムシート１８などを支持し、拡散板１７及びプリズムシート１８が内側に撓まないようにしている。   The lamp clip 12 grips the straight tube portion of the CCFL 13 at the grip portion 12b. The lamp clip 12 is provided with a conical column portion 12c. The column portion 12c supports the diffusion plate 17 and the prism sheet 18, and the diffusion plate 17 and the prism sheet 18 are bent inward. I try not to stop.

第１板材１０の裏面側、すなわちＣＣＦＬ１３が設けられた側の反対側には、ハニカム構造の補強部材１５及び第２板材１６がこの順序で積層配置されている。   On the back side of the first plate member 10, that is, the side opposite to the side on which the CCFL 13 is provided, the reinforcing member 15 and the second plate member 16 having a honeycomb structure are laminated in this order.

補強部材１５は平面視が六角形のセル１５ａを有しており、図３に示すように、切込み１５０ａを千鳥配置で設けた板材１５０の両辺を外向きの力で引っ張ることで、六角形のセル１５ａを有する補強部材１５を容易に得ることができる。ハニカム構造は、軽量かつ高剛性であることから、バックライト装置の重量を増大させることなく、機械的強度を高めることができるため、特に大型の表示装置に好適である。なお、貫通孔１０ａと補強部材１５の壁部が重なってしまうと、ランプクリップ１２の係止部１２ａを貫通孔１０ａに挿入して係止することができなくので、図４に示すように、第１板材１０に設ける貫通孔１０ａの位置が、補強部材のセル１５ａの内部になるように設計しておく。   The reinforcing member 15 has a hexagonal cell 15a in plan view, and as shown in FIG. 3, by pulling both sides of the plate member 150 provided with the notches 150a in a staggered arrangement with an outward force, The reinforcing member 15 having the cell 15a can be easily obtained. Since the honeycomb structure is lightweight and highly rigid, the mechanical strength can be increased without increasing the weight of the backlight device, and thus the honeycomb structure is particularly suitable for a large display device. If the through hole 10a and the wall portion of the reinforcing member 15 overlap, the locking portion 12a of the lamp clip 12 cannot be inserted into the through hole 10a and locked, so as shown in FIG. It is designed so that the position of the through hole 10a provided in the first plate 10 is inside the cell 15a of the reinforcing member.

第２板材１６には貫通孔が未形成であり、図１の矢符Ｌに示したように、ＣＣＦＬ１３の光が第１板材１０の貫通孔１０ａを通じて第１板材１０の裏面側に漏れた場合であっても、第２板材１６の存在によって第２板材１６の裏面側に漏れることはない。なぜなら、貫通孔１０ａを通じて、第１板材１０、補強部材１５の壁部及び第２板材１６によって形成される空間に導光された光は、その空間によって減衰されるまで反射を繰り返すか、又は貫通孔１０ａを通じて元のＣＣＦＬ１３側へ導光することから、第２板材１６の裏面側に漏れることはない。これにより、ＣＣＦＬ１３の光は液晶パネルが配置された方向にのみ光が出射される。   When the through hole is not formed in the second plate member 16 and the light of the CCFL 13 leaks to the back side of the first plate member 10 through the through hole 10a of the first plate member 10 as shown by the arrow L in FIG. Even so, the presence of the second plate member 16 does not leak to the back side of the second plate member 16. This is because the light guided to the space formed by the first plate member 10, the wall portion of the reinforcing member 15 and the second plate member 16 through the through hole 10a repeats reflection until it is attenuated by the space, or penetrates. Since light is guided to the original CCFL 13 side through the hole 10a, it does not leak to the back side of the second plate member 16. Thereby, the light of CCFL13 is emitted only in the direction in which the liquid crystal panel is disposed.

また、第２板材１６には貫通孔が未形成であることから、バックライト装置の内部に、外部からの光が流入したり、異物が流入したりすることを防止できる。したがって、異物のＣＣＤＬ１３の電極への付着を防ぎ、装置寿命の短縮を防止することができる。しかも、不織布を板材へ貼付する従来の形態（図７参照）と比較した場合、意匠性に優れており、商品価値を向上することができる。   Further, since the through hole is not formed in the second plate member 16, it is possible to prevent light from the outside or foreign matter from flowing into the backlight device. Accordingly, it is possible to prevent foreign matter from adhering to the electrode of the CCDL 13 and to prevent the apparatus life from being shortened. And when compared with the conventional form (refer FIG. 7) which sticks a nonwoven fabric to a board | plate material, it is excellent in design property and can improve a commercial value.

ところで、第１板材１０の裏面側に、補強部材１５及び第２板材１６をこの順序で配置することによって、ランプクリップ１２の係止部１２ａを触れることができなくなるため、ランプクリップ１２を第１板材１０から取り外すことができなくなる場合がある。そこで、図５に示すように、第１板材１０に、ランプクリップ１２が配置された領域Ｒを取り囲むように孔群（ミシン目）１０ｂを設け（図５（ａ））、ランプクリップ１２を第１板材１０の領域Ｒの部分ごと、押圧によって除去する（図５（ｂ））。除去された領域Ｒの第１板材１０からランプクリップ１２のみを取り外すことができるので、各部材をリサイクルすることができる。   By the way, by arranging the reinforcing member 15 and the second plate material 16 in this order on the back surface side of the first plate material 10, it becomes impossible to touch the locking portion 12 a of the lamp clip 12. In some cases, it may become impossible to remove the plate 10. Therefore, as shown in FIG. 5, a hole group (perforation) 10b is provided in the first plate member 10 so as to surround a region R where the lamp clip 12 is disposed (FIG. 5A), and the lamp clip 12 is attached to the first plate member 10. The entire region R of the one plate material 10 is removed by pressing (FIG. 5B). Since only the lamp clip 12 can be removed from the first plate member 10 in the removed region R, each member can be recycled.
