Description of the new model: [Technical field to which the new model belongs] The new model relates to a backlight module, especially a light guide plate of the backlight module. [Previous technology] Liquid crystal display (LCD) is a driving circuit mounted on the LCD panel, and then • a microprocessor (CpU) is used to drive the LCD panel, but since the liquid crystal itself does not | will emit light, a separate light source must be installed behind Only when the light passes through the liquid crystal can it show no effect, and the technology that emits light from behind is collectively called backlight (back light). Moonlight module (BLM) is to convert point or line light sources into surface light sources to provide liquid crystal displays. Performance of the light-emitting display effect, and with the configuration of the light source and the light-emitting method are different, backlight modules often have side-light type (Side_Edge Gayun and direct type) and other design types. See Figure 1, is a conventional Brief structure diagram of edge-lit backlight module 丨, gram holder 11, a light source 12 installed on the side of the box holder 11, a light guide plate 13 on the side, and a light guide plate in order
一位在該光源12旁侧 13上方之一下擴散片】 的疋’為了提高光源 板本體13 1遠離光源 並配合參閱圖2，須進一步說明的是， 貼附一層反射片 U光線之利用率，該導光板13會在一板本 12之二側邊上，分別藉由一雙面膠帶η〕 5 M277948 ，且該盒座U亦在一座本體lu之頂面上利用一雙面膠 帶112貼附一層反射片113，用於提供光線反射的介面。使 用時，光源12之光線會侧向射入導光板13，並透過導光板 13折射向外導出，此時，部份向外之光線會照射在反射片 133上，並被反射回板本體131，而部份向下透出之光線則 會照射在該盒座U之反射#113 i ’再被反射向上穿過導 光板13，以與部份直接向上透出導光板13之光線，一同通 過下擴散4 14、增光片15與上擴散片16，最後向上照射 至一液晶面板（圖未示）發光顯示。 •然而，當上述反射片133、113貼設時，須先將雙面膠 帶132、112分別貼設在該板本體131與座本體iu上，再 令反射片Π3、113對準貼置在雙面膠帶132、112上’黏貼 時必須小心謹慎地調整對位與貼合，否則容易發生歪斜、 皺稽或形成氣泡等現象’容易造成產品品質瑕视不良，因 此在貼設時較為費工耗時，相對會提高加工成本。此外， 由於導絲13底侧並未設置反射片133，因此穿出導光板 13底側之光線，必須向下照射到盒座u之反射片ιΐ3才會 反射，而反射後光線的路徑又不一定會完全朝肖導光板二 ，所以可能會有漏光之虞，導致光線之利用率較低。 【新型内容】 口此本新型之目的，即在提供一種本體外直接塗佈 有反射層以達到簡易製造功效的導光板。 而且’本新型之另一目的，即在提供一種能提昇光線 利用率的導光板。 M277948 於疋’本新型導光板，是裝設在背光模組之光源一側 ’且用於將光源的光線反射向一液晶面板，並包含：一本 體，及一反射層。該本體能供,光源之光線進入且將光線向 外折射’並具有一鄰近於液晶面板的頂面、一相反於頂面 的底面、至少一銜接頂、底面且鄰近光源以供光線射入的 導光面’及至少一銜接頂、底面且遠離光源的反光面。該 反射層是塗佈結合在該本體之反光面上，用於將光線反射 向本體。A diffusing sheet under one above the side 13 of the light source 12] In order to increase the light source plate body 13 1 away from the light source and coordinate with reference to FIG. 2, it must be further explained that the utilization rate of light attached to a layer of reflective sheet U, The light guide plate 13 is attached to the two sides of a plate 12 with a double-sided tape η] 5 M277948, and the box holder U is also attached with a double-sided tape 112 on the top surface of a body lu. A layer of reflective sheet 113 is used to provide an interface for reflecting light. When in use, the light from the light source 12 will enter the light guide plate 13 sideways and be refracted outward through the light guide plate 13. At this time, part of the outward light will be irradiated on the reflection sheet 133 and reflected back to the plate body 131 And part of the light that is transmitted downward will shine on the reflection # 113 i of the box base U and then be reflected upward and pass through the light guide plate 13 to pass with the part of the light that directly penetrates the light guide plate 13 upward. The lower diffuser 4 14, the light-increasing sheet 15 and the upper diffuser sheet 16 are finally illuminated upward to a liquid crystal panel (not shown) for light emitting display. • However, when the above-mentioned reflective sheets 133 and 113 are attached, the double-sided adhesive tapes 132 and 112 must be attached to the board body 131 and the base body iu, respectively, and then the reflective sheets Π3 and 113 are aligned and placed on the double sheet. The masking tapes 132 and 112 must be carefully adjusted for alignment and bonding when they are stuck, otherwise they are prone to skewing, wrinkling, or the formation of air bubbles. It is easy to cause poor product quality, so it is more labor-intensive when mounting. Time, the processing cost will be relatively increased. In addition, since the reflection sheet 133 is not provided on the bottom side of the guide wire 13, the light passing through the bottom side of the light guide plate 13 must be reflected down to the reflection sheet ι3 of the box holder u, and the path of the light after reflection is not. It will definitely go towards Xiao LGP 2 completely, so there may be the risk of light leakage, resulting in low utilization of light. [New content] The purpose of this novel model is to provide a light guide plate directly coated with a reflective layer outside the body to achieve simple manufacturing effects. Moreover, another object of the present invention is to provide a light guide plate capable of improving light utilization efficiency. M277948 Yu 疋 This new type of light guide plate is installed on the light source side of the backlight module and is used to reflect the light from the light source to a liquid crystal panel, and includes: a body and a reflective layer. The body can provide that the light of the light source enters and refracts the light outwards and has a top surface adjacent to the liquid crystal panel, a bottom surface opposite to the top surface, at least one connecting top, bottom surface and adjacent to the light source for light to enter The light-guiding surface 'and at least one reflective surface connected to the top and bottom surfaces and away from the light source. The reflective layer is coated and combined on the light-reflecting surface of the body to reflect light toward the body.
