Description

光源裝置及背光模組Light source device and backlight module

本發明係關於一種光源裝置及背光模組。具體而言，本發明係關於一種側入式光源裝置及包含其之背光模組。The invention relates to a light source device and a backlight module. Specifically, the present invention relates to an edge light source device and a backlight module containing the same.

現今的背光模組技術大致分為直下式與側入式兩種；直下式發光背光技術是把多枚光源(例如：發光二極體)排成陣列，放在散光片及液晶顯示器後面，直接照射液晶顯示器；側入式背光技術是把光源放在液晶顯示器的一邊，光線進入導光板後，導光板即引導光線平均及分布地照到液晶顯示器背部。後者的佈設減少了光源的使用，故可使顯示螢幕的設計更為輕薄，也減低了生產成本及能耗。而將光源放在液晶顯示器的四邊或上下兩邊的側入式背光技術，在不斷的技術演進下發展至將光源設置於一長條之軟性電路板上，即形成所謂的光條(light bar)。Today's backlight module technology can be roughly divided into two types: direct-type and side-type; direct-type light-emitting backlight technology is to arrange multiple light sources (such as light-emitting diodes) in an array, placed behind the diffuser and liquid crystal display, directly Illuminate the liquid crystal display; the edge-type backlight technology puts the light source on one side of the liquid crystal display. After the light enters the light guide plate, the light guide plate guides the light to the back of the liquid crystal display evenly and distributed. The arrangement of the latter reduces the use of light sources, so the design of the display screen can be made lighter and thinner, and the production cost and energy consumption are also reduced. The side-lit backlight technology that places the light source on the four sides or the upper and lower sides of the liquid crystal display has been developed to place the light source on a long flexible circuit board under continuous technological evolution, forming a so-called light bar (light bar) .

為提高面板的解析度，液晶顯示螢幕亮度的提升為一重要課題。然以發光二極體作為光源為例，礙於晶片驅動電壓限制，亮度的提升會造成發光二極體並聯的增加，而發光二極體並聯增加時則會因其線路增加而造成軟性電路板板寬的增加，使背光模組無法薄化。In order to improve the resolution of the panel, the improvement of the brightness of the liquid crystal display screen is an important issue. However, taking light-emitting diodes as light sources as an example, due to the limitation of chip driving voltage, the increase in brightness will increase the parallel connection of light-emitting diodes, and the increase of light-emitting diodes in parallel will cause flexible circuit boards due to the increase in their circuits. The increase in board width prevents the backlight module from being thinned.

若欲改善電路板板寬增加的問題，其中一種解決方案為將背光模組中的單條光條分成兩條；然而由單條光條增加為兩條光條，所增加的光條與及對應設置的連接器數量卻可能造成了製造成本的提升及設計與製造上的負擔。If you want to improve the problem of increasing the width of the circuit board, one of the solutions is to divide the single light strip in the backlight module into two; however, the single light strip is increased to two light strips, and the added light strips are corresponding to However, the number of connectors may increase the manufacturing cost and burden the design and manufacturing.

本發明之一目的在於提升光源裝置亮度的同時，減少基板寬度的增加。One object of the present invention is to improve the brightness of the light source device while reducing the increase in the width of the substrate.

圖1為根據本發明一實施例所繪示的光源裝置示意圖。如圖1所示，光源裝置100包含基板110及複數個光源210。於較佳實施例中，光源裝置100為發光二極體背光液晶顯示螢幕之發光二極體光條；其中基板110為具可撓性之軟性印刷電路板(Flexible Printed Circuit, FPC)，可依設計需求進行彎折，而光源210為發光二極體。基板110具有光源承載區115，光源承載區115具有第一邊111，第一邊111係沿一第一邊方向112延伸；光源210設置於光源承載區115上。於較佳實施例中，光源承載區115形成為直線形的長條狀，第一邊111則為其長邊。然而在不同實施例中，光源承載區115亦可為弧曲的長條或其他形狀。FIG. 1 is a schematic diagram of a light source device according to an embodiment of the invention. As shown in FIG. 1, the light source device 100 includes a substrate 110 and a plurality of light sources 210. In a preferred embodiment, the light source device 100 is a light-emitting diode light bar of a light-emitting diode backlit liquid crystal display screen; wherein the substrate 110 is a flexible printed circuit board (Flexible Printed Circuit, FPC), which can be The design requires bending, and the light source 210 is a light emitting diode. The substrate 110 has a light source carrying area 115, the light source carrying area 115 has a first side 111, and the first side 111 extends along a first side direction 112; the light source 210 is disposed on the light source carrying area 115. In a preferred embodiment, the light source carrying area 115 is formed in a linear strip shape, and the first side 111 is its long side. However, in different embodiments, the light source carrying area 115 may also be a curved strip or other shapes.

如圖1及所示，光源210分為複數個光源組220，各光源組220較佳沿第一邊方向112依序設置於光源承載區115上。各光源組220中具有一個終端光源組225；在本實施例中，終端光源組225係為設置於光源承載區115靠近端部處，且為各光源組220中排列最末的一組；然而在不同實施例中，終端光源組225亦可不排列於最末，而為串聯順序上為終端之一組。光源組220內之光源210沿第一邊方向112分佈，每一光源210與其他光源組中之光源210串聯以形成複數串接。上述『沿第一邊方向分佈』係包含但不限於光源210呈直線排列且所排列形成之直線平行於第一邊方向112的狀況；在不同實施例中，光源210亦可不呈直線排列。 As shown in FIG. 1 and as shown in FIG. 1, the light source 210 is divided into a plurality of light source groups 220, and each light source group 220 is preferably arranged on the light source carrying area 115 in sequence along the first side direction 112. Each light source group 220 has a terminal light source group 225; in this embodiment, the terminal light source group 225 is arranged near the end of the light source carrying area 115, and is the last group in each light source group 220; however, In different embodiments, the terminal light source group 225 may not be arranged at the end, but is a group of terminals in the serial sequence. The light sources 210 in the light source group 220 are distributed along the first side direction 112, and each light source 210 is connected in series with the light sources 210 in other light source groups to form a plurality of series connections. The aforementioned "distributed along the first side direction" includes, but is not limited to, the situation where the light sources 210 are arranged in a straight line and the line formed by the arrangement is parallel to the first side direction 112; in different embodiments, the light sources 210 may not be arranged in a straight line.

圖2為根據本發明一實施例所繪示的光源裝置之負極線佈線示意圖。如圖2所示，以60顆光源為例，可分為12個光源組，每組包含5顆光源。將各光源依序標記為L1、L2、L3...Ln-2、Ln-1、Ln；L1~L5為第一光源組230，L6~L10為第二光源組240，.....Ln-4~Ln為終端光源組225。光源L1的負極以線路連接至光源L6的正極，再以線路從光源L6的負極連接至光源L11的正極，依此類推，經過12個光源組220後連接至光源Ln-4的正極，此為各光源組220所形成之一組串接。在本實施例中共有5條串接，每一串接對應於基板110上設有負極線321~325分別連接終端光源組225中之光源Ln-4~Ln。在光源承載區115內，光源Ln-3~Ln的負極線322、323、324及325分別自光源Ln-3~Ln朝第一邊111延伸，並於抵達光源承載區115靠近第一邊111的部分時向左彎折。其中負極線323與負極線324在彎折為沿第一邊111延伸後至少有部分是並排的，也就是在橫切第一邊方向112的方向上並排；負極線324及負極線325在彎折為第一邊111延伸後亦有部分是並排的。光源Ln-4的負極線321自光源Ln-4延伸，並於抵達光源承載區115 靠近第一邊111的部分時向右彎折。如圖2所示，於橫切第一邊方向112上光源Ln-4的負極線321不與光源Ln-3~Ln的負極線322、323、324及325同時並排；換言之，在光源承載區115內負極線321~325在橫切第一邊方向112的方向上有部分並排，但不全部同時並排。橫切第一邊方向112的方向例如可以是垂直第一邊方向112的方向，但不以此為限。從另一角度來看，若將各負極線321~325均投影至第一邊方向112上，則至少有部分負極線的分佈範圍是不重疊的，例如負極線321與其他負極線322~325即不重疊。 2 is a schematic diagram of the wiring of the negative wire of the light source device according to an embodiment of the invention. As shown in Figure 2, taking 60 light sources as an example, they can be divided into 12 light source groups, each group containing 5 light sources. Mark the light sources as L 1 , L 2 , L 3 ... L n-2 , L n-1 , L n in sequence; L 1 to L 5 are the first light source group 230, and L 6 to L 10 are Two light source groups 240,...L n-4 ~L n are terminal light source groups 225. The negative pole of the light source L 1 is connected to the positive pole of the light source L 6 by a wire, and then the negative pole of the light source L 6 is connected to the positive pole of the light source L 11 by a wire, and so on, after 12 light source groups 220 are connected to the light source L n-4 The positive electrode of the light source group 220 is connected in series. In this embodiment, there are 5 serial connections, and each serial connection corresponds to the negative wires 321 to 325 provided on the substrate 110 to connect the light sources L n-4 to L n in the terminal light source group 225 respectively. Bearing area 115 in the light source, the light source L 3 n-~ L n negative line 322,323,324 and 325 from the light source L n-3 ~ L n respectively extending toward the first side 111, and the carrier is close to the light source 115 arrive The part of the first side 111 is bent to the left. The negative wire 323 and the negative wire 324 are at least partially side by side after being bent to extend along the first side 111, that is, side by side in the direction transverse to the first side direction 112; the negative wire 324 and the negative wire 325 are bent After the first side 111 is folded, some parts are side by side. Source lines L n-4 of the negative electrode 321 from the light source L n-4 extends, and arrived at the light source when the carrier block the bent portion near the right side 111 of the first 115. As shown in FIG. 2, the negative line 321 of the light source L n-4 is not parallel to the negative lines 322, 323, 324, and 325 of the light source L n-3 ~ L n in the direction 112 transverse to the first side; in other words, The negative wires 321 to 325 in the light source bearing area 115 are partially aligned in a direction transverse to the first side direction 112, but not all are aligned at the same time. The direction transverse to the first side direction 112 may be, for example, a direction perpendicular to the first side direction 112, but is not limited thereto. From another point of view, if all the negative lines 321 to 325 are projected onto the first side direction 112, at least some of the negative lines do not overlap, for example, the negative line 321 and other negative lines 322 to 325 That is, no overlap.

藉由上述設計，由於在橫切第一邊方向112的方向上不會同時存在全部的負極線321~325，因此光源承載區115在此一方向上的寬度則可得到控制而不會過寬。 With the above design, since all the negative lines 321 to 325 do not exist at the same time in the direction transverse to the first side direction 112, the width of the light source carrying area 115 in this direction can be controlled without being too wide.

如圖2所示，若將每一光源組220中的第一顆光源稱為第一光源211，第二顆光源稱為第二光源212，則各光源組中的第一光源211彼此串聯形成一串接，第二光源212彼此串聯形成另一串接。在第一邊方向112上，每一第二光源212係位於同一光源組之第一光源211及相鄰光源組之第一光源211之間。終端光源組225中之第一光源211及第二光源212，亦即光源Ln-4及光源Ln-3連接此二光源之負極線320可分別稱為第一負極線321及第二負極線322。如前所述，第一負極線321及第二負極線322分別自第一光源211及第二光源212朝第一邊111延伸並朝不同方向彎折。終端光源組225位於光源承載區115之一端；基板110具有連接部116連接光源承載區115之第一邊111靠近終端光源組225之位置，負極線320分別延伸至連接部116上，以連接於連接部116上的接點。 As shown in FIG. 2, if the first light source in each light source group 220 is called the first light source 211, and the second light source is called the second light source 212, the first light sources 211 in each light source group are connected in series to form One series connection, the second light sources 212 are connected in series to form another series connection. In the first side direction 112, each second light source 212 is located between the first light source 211 of the same light source group and the first light source 211 of the adjacent light source group. The first light source 211 and the second light source 212 in the terminal light source group 225, that is, the light source L n-4 and the light source L n-3 are connected to the negative line 320 of the two light sources, which can be called the first negative line 321 and the second negative line, respectively Line 322. As mentioned above, the first negative wire 321 and the second negative wire 322 respectively extend from the first light source 211 and the second light source 212 toward the first side 111 and are bent in different directions. The terminal light source group 225 is located at one end of the light source carrying area 115; the substrate 110 has a connecting portion 116 connected to the first side 111 of the light source carrying area 115 near the terminal light source group 225, and the negative wire 320 respectively extends to the connecting portion 116 to be connected to A contact on the connecting portion 116.
