1351562 九、發明說明： 【發明所屬之技術領域】 本發明係關於一種背光模組、液晶顯示裝置及其製造 方法’特別關於一種可執行亮度分區控制之背光模組、液 晶顯示裝置及其製造方法。 【先前技術】 隨著平面顯示裝置（Flat Panel Display, FPD)技術的 發展，液晶顯示裴置因具有體型輕薄、低功率消耗及無輻 射等優越特性，已經漸漸地取代傳統陰極射線管（Cathode Ray Tube，CRT)顯示裝置，並且應用至各式電子產品。一 般液晶顯示裝置主要係由一液晶顯示面板（Liquid Crystal Display Panel)與一背光模組（Backlight Module)組合而 成0 請參照圖1所示，一種習知的背光模組1係包含一光 源 11、一 導光板（Light-Guiding Plate, LGP) 12、一光擴 散片（Optical Diffusing Sheet) 13 以及一稜鏡片（Prism Sheet) 14。其中，光源11係鄰設於導光板12之一入光面 121，光擴散片13係鄰設於導光板12之一出光面122，而 棱鏡片14係鄰設於光擴散片13之一側，此外，導光板12 於其底面123具有複數印刷網點124，印刷網點124係有 散射光線的功用。 請參照圖2所示，當光源11發出光線時，光線經由 入光面121進入導光板12並在導光板12内進行全反射，1351562 IX. The invention relates to a backlight module, a liquid crystal display device and a manufacturing method thereof, in particular to a backlight module capable of performing brightness division control, a liquid crystal display device and a manufacturing method thereof . [Prior Art] With the development of flat panel display (FPD) technology, liquid crystal display devices have gradually replaced traditional cathode ray tubes (Cathode Ray) due to their superior characteristics such as thin body size, low power consumption and no radiation. Tube, CRT) display device, and applied to a variety of electronic products. Generally, a liquid crystal display device is mainly composed of a liquid crystal display panel and a backlight module. Referring to FIG. 1 , a conventional backlight module 1 includes a light source 11 . A Light-Guiding Plate (LGP) 12, an Optical Diffusing Sheet 13 and a Prism Sheet 14. The light source 11 is disposed adjacent to one of the light-incident surfaces 121 of the light guide plate 12, and the light-diffusing sheet 13 is disposed adjacent to one of the light-emitting surfaces 122 of the light guide plate 12, and the prism sheet 14 is disposed adjacent to one side of the light-diffusing sheet 13. In addition, the light guide plate 12 has a plurality of printed dots 124 on the bottom surface 123 thereof, and the printed dots 124 have the function of scattering light. Referring to FIG. 2, when the light source 11 emits light, the light enters the light guide plate 12 via the light incident surface 121 and is totally reflected in the light guide plate 12.
5 1351562 當光線經過導光板12之印刷網點124時，會產生散射而 破壞光線的全反射現象，造成部分光線折射出導光板12 之出光面122。然後，光線再經過光擴散片13及稜鏡片 14,並藉由光擴散片13及稜鏡片14得到良好的光線性 質，如光線均勻化、高亮度等等。此外，在導光板12上 之印刷網點124之分佈通常是不均勻的，因為對導光板12 而言，越靠近光源11之出光面122具有較高之亮度，所 以越遠離光源11之印刷網點124分佈越密，使得較遠離 光源11之出光面122能有較多之光線通過，進而使整個 出光面122之亮度平均。最後，光線係透過液晶顯示面板 而成為多采多姿的畫面。其中，液晶顯示面板係主要由二 玻璃基板夾置一液晶層。 當光線通過液晶顯示面板時，藉由控制液晶層中之液 晶分子的旋轉，可使光線具有亮度的變化，再經由濾光片 所帶來的混光效果，就可產生五彩繽紛的光線，這也是一 般用於液晶顯示裝置的亮度及光線控制方法。然而，在這 種方式之下，光源11係維持於開啟的狀態，其不僅耗電 且使得背光模組1的溫度升高，此外，由於液晶分子並無 法完全阻擋光線通過，因此在光源11維持開啟的狀態下， 液晶分子仍會產生漏光的現象，如此一來，將會降低顯示 畫面對比度。 承上所述，為解決不易達到高對比的問題，近來一種 用於液晶顯示裝置之亮度控制方法，係藉由液晶顯示裝置 内的影像處理器對影像的資料進行分析，然後將影像劃分5 1351562 When the light passes through the printing dot 124 of the light guide plate 12, a total reflection phenomenon which scatters and destroys the light is generated, and part of the light is reflected off the light emitting surface 122 of the light guide plate 12. Then, the light passes through the light diffusion sheet 13 and the cymbal sheet 14, and the light diffusion sheet 13 and the cymbal sheet 14 are used to obtain good optical linearity such as uniformity of light, high brightness, and the like. In addition, the distribution of the printed dots 124 on the light guide plate 12 is generally non-uniform, because the light-emitting surface 122 closer to the light source 11 has a higher brightness for the light guide plate 12, so the farther away from the printed dots 124 of the light source 11 The denser the distribution, the more light passing through the light exit surface 122 of the light source 11 can pass, thereby averaging the brightness of the entire light exit surface 122. Finally, the light is transmitted through the liquid crystal display panel to become a multi-faceted picture. Among them, the liquid crystal display panel mainly has a liquid crystal layer sandwiched between two glass substrates. When the light passes through the liquid crystal display panel, by controlling the rotation of the liquid crystal molecules in the liquid crystal layer, the light can be changed in brightness, and then the light mixing effect brought by the filter can generate colorful light, which is also Generally used for brightness and light control methods of liquid crystal display devices. However, in this manner, the light source 11 is maintained in an open state, which not only consumes power but also raises the temperature of the backlight module 1, and further, since the liquid crystal molecules cannot completely block the passage of light, they are maintained at the light source 11. When it is turned on, liquid crystal molecules will still leak light, which will reduce the contrast of the display. As described above, in order to solve the problem that it is difficult to achieve high contrast, a recent brightness control method for a liquid crystal display device analyzes image data by an image processor in a liquid crystal display device, and then divides the image.
6 1351562 為複數區域，例如圖3所示係劃分為四個區域，再依據分 區資料對背光模組做不同分區的亮度控制。由於光線之整 體亮度係由背光模組之光源所發射光線之亮度及液晶分 子的旋轉角度而共同決定，所以當影像處理器分析某一分 區，例如圖3所示之第一區之影像資料時，可以在光源之 消耗功率及液晶分子的旋轉角度之間做調整，而得到相同 的亮度，例如可以將光源之功率調降，將液晶旋轉的角度 調大’而得到相同的亮度，如此一來，便可以降低整體的 消耗功率並且降低背光模組之溫度，此外，更可提高對 比。然而，此種控制方式具有各區之間會互相影響的缺點。 因此，如何提供一種背光模組、液晶顯示裝置及其製 造方法，可同時達到亮度分區控制以降低背光模組之消耗 功率並提咼晝面對比，以及減少各分區之間相互影響，進 而提升背光模組之發光效能，實為當前重要課題之一。 【發明内容】 有鑑於上述課題，本發明之目的為提供一種可以同時 達到亮度分區控制以及減少各分區之間相互影響，進而提 升整體效能之背光模組、液晶顯示裝置及其製造方法。 緣是，為達上述目的，依據本發明之一種背光模組係 包含-第-導光板及至少二第m導光板係具有 至少二第-導光區及至少—第—非導光區；第—光源係分 別與第一導光區對應設置。 另外，為達上述目的，依據本發明之一種液晶顯示裝 1351562 置係包含一背光模組及一液晶面板模組。背光模組係具有 一第一導光板及至少二第一光源，第一導光板係具有至少 二第一導光區及至少一第一非導光區，第一光源係分別與 第一導光區對應設置。液晶面板模組係鄰設於背光模組。 又，為達上述目的，依據本發明之一種背光模組之製 造方法係包含在一第一導光板上形成至少二第一導光區 及至少一第一非導光區；以及將至少二第一光源分別對應 第一導光區設置。 再者’為達上述目的，依據本發明之一種液晶顯示裝 置之製造方法係包含在一第一導光板上形成至少二第— 導光區及至少一第一非導光區；將至少二第一光源分別對 應第一導光區設置；以及將一液晶面板模組相對於該第一 導光板設置。 承上所述，因依據本發明之一種背光模組、液晶顯示 裝置及其製造方法’係藉由在導光板上設置至少二導光區 及至少一非導光區，再將至少二光源分別對應導光區設 置，所以各導光區可藉由調整對應設置光源之功率或驅動 訊號來進行亮度控制，另外，非導光區可作為二導光區之 缓衝地帶，而減少各導光區之相互影響。與習知技術相 較，本發明可以同時達到亮度分區控制並減少各分區之相 互影響，進而降低消耗功率並提高對比，且可增加背光模 組之發光效能。 【實施方式】 1351562 以下將參照相Μ式，說明依據本發明較佳實施例之 一種背光模組'液晶顯示裝置及其製造方法。 請參照圖4所示’本發明較佳實施例之一種背光模組 2係包含一第一導光板P01及二第—光源“〗。其中，第一 導光板p01係具有二第一導光區A〇l及二第一非導光區 NA01，且第一光源L01係分別與第一導光區Α〇ι對應設置。 在本實施例中’第一導光板P01可為矩形板、楔形板 或其他形狀之平板’第一光源Lw可包含一冷陰極營光燈 (Cold Cathode Fluorescent Lamp, CCFL)、一發光二極體 (Light Emitting Diode, LED )、一有機電激發光元件 (Organic ElectroLuminescent Device, OELD )或一場發身十 元件（Field Emission Device，FED)等等，於此係以發光 二極體為例。 另外，本實施例之第一導光區A01係具有複數個第一 網點或複數個第一微結構，這些網點或微結構可使光線產 生散射而破壞光線的全反射現象，造成部分光線可折射出 第一導光板Ρ〇ι之出光面Poll，而第一非導光區NA01則不 具有網點或微結構，所以對第一導光板p01而言，會有相 對較多之光線自第一導光區A01所對應之出光面卩011射 出’會有相對較少之光線自第一非導光區ΝΑ〇ι所對應之 出光面P011射出。 於本實施例中，背光模組2更包含一第二導光板P02， 其係具有二第二導光區A〇2及二第二非導光區NA02,且第 二導光板P〇2係與第一導光板Ρ〇ι相對而設，此外，二個第 1351562 -非導光區NAgi係與二個第二導光區相對而設，而二 個第二非導光區NAq2係與二個第—導光區^相對而設。 另外β光模組2更包含二第二光源L⑽， 二導光區A〇2對應設置。 弟 在本貝施例中，第二光源L〇2之種類係可盥第一光源 W相同’故於此不再贅述。另外，第二導光區、具有複 數個第m複數個第二微結構，這些第二網點或第二6 1351562 is a complex area, for example, as shown in Figure 3, divided into four areas, and then the backlight module is controlled by different partitions according to the partition data. Since the overall brightness of the light is determined by the brightness of the light emitted by the light source of the backlight module and the rotation angle of the liquid crystal molecules, when the image processor analyzes a certain area, such as the image data of the first area shown in FIG. It is possible to adjust between the power consumption of the light source and the rotation angle of the liquid crystal molecules to obtain the same brightness, for example, the power of the light source can be adjusted down, and the angle of the liquid crystal rotation can be increased to obtain the same brightness, thus obtaining the same brightness. In this way, the overall power consumption can be reduced and the temperature of the backlight module can be lowered, and in addition, the contrast can be improved. However, this type of control has the disadvantage that the zones will interact with each other. Therefore, how to provide a backlight module, a liquid crystal display device and a manufacturing method thereof can simultaneously achieve brightness partition control to reduce the power consumption of the backlight module and improve the face ratio, and reduce the mutual influence between the partitions, thereby improving The luminous performance of the backlight module is one of the most important issues at present.

It is worthwhile to compare, as shown in FIG. 5, which is a cross-sectional view of the first light guide plate Pw in FIG. 4 along the AA line. In this embodiment, the first light guiding area A01 has a plurality of dots. For example, the first halftone point Np is disposed on the surface of the first light guide plate P01i, where the first halftone point Np is on the surface of the light exiting surface P011. In addition, on the first light guiding region, the density of the first mesh point Np or the first microstructure close to the first light source LG1 is smaller than the first mesh point Np or the first microstructure farther from the first light source Lqi. The density, as such, can make the light-emitting surface P011 corresponding to the whole (four)-light-guiding area' have a relatively uniform brightness. Referring to FIG. 4 again, in the second step, the difference between the second light guide plate p〇2 and the first light guide plate Pen is that the second guide wire Aq2 is different from the first light guide area A01. In the present embodiment, the first light guide plate p〇i and the first light guide plate P〇2 are respectively divided into four regions Jn, 羾, and 贝, and the first light guide region A01 is disposed on the first light guide plate P01. z, melon, and the second light guiding area a02 is disposed in the region n on the second light guiding plate p〇2, so that on the first light guiding plate p〇1, the two first light guiding regions are Α〇ι As the two brightness control areas, the two second light guiding areas A 〇 2 also become two brightness control areas on the second light guide plate P 〇 2, and the backlight module 2 can be divided into four brightness control groups. By independently adjusting the driving signals of the two first light sources respectively corresponding to the two guiding regions, the area ag1 and the two second light sources L〇2 respectively corresponding to the two second light guiding areas AQ2, Perform brightness control. In addition, the λ thin* example distributes the two first light guiding areas a01 and the two second light guiding areas A 〇 2 on the first light guiding plate P01 and the second light guiding plate P 〇 2, the: non-light guiding area The NA0& second non-light-guiding area NA〇2 can serve as a buffer zone of the first light guiding area A01 and the second light guiding area A〇2, respectively, to reduce each of the first light guiding area A〇1 and each second light guiding area. The brightness unevenness caused by the interaction between A02. In addition, the backlight module 2 of the present embodiment takes four brightness control areas as an example, and it should be noted that the light guide plate, the light guide area, the non-light guide area or the light source may be different according to the number of the divided brightness control areas. The number will also vary. When the backlight module is divided into a plurality of brightness control dragons, it is necessary to have a light guide plate to disperse the light guiding area 'and set the light collecting area as a buffer zone of each light guiding area' and the light guiding area on each light guiding plate The sum of the numbers is equal to the number of brightness control zones, and in addition, the number of light sources is also equal to the number of brightness control zones. Hereinafter, the backlight module 3 of another preferred embodiment of the present invention will be described by taking 16 brightness control areas as an example. 1351562, as shown in FIG. 6, the backlight module 3 has a P11: a second light guide plate P12, a third light guide plate Pu, and a fourth guide = 7 'the first light guide plate Pu has four first guides The light area Au, the second light guide plate Pi2 has four first-mole F Δ, four fourth 4th u, four fourth, nine, and four fourth on each light guide plate, not part of the light guide area = and not The light guiding area serves as a buffer zone of the light guiding area, and the light area may be a first-non-light guiding light-guide light NA "12 second non-light guiding area NAl3 and - fourth non-cold first £ NAU.
