Description
本發明關於一種導光板及背光模組。 The invention relates to a light guide plate and a backlight module.
圖4顯示一習知導光板的網點結構的配置形態示意圖。如圖4所示,網點結構102設置於一導光板100的底面104,入光面106鄰近光源108,底面104包含鄰近導光板100的入光面106的一第一區域P及遠離入光面106的一第二區域Q,網點結構102可包含分佈於第一區域P的一第一網點群102a及分佈於第二區域Q的第二網點群102b。如圖4所例示的習知設計,通常將所有區域的兩相鄰網點的間距均設為相同,例如第一網點群102a中任兩相鄰網點的網點間距d1均相同,且網點間距d1會等於第二網點群102b中任兩相鄰網點的網點間距d2,然而,隨著光程距離增加使光能逐漸衰減,於光程較遠的位置(例如遠離入光面106的第二區域Q)通常需提高網點分布密度以滿足光學設計要求,故習知設計的第二網點群102b的網點尺寸會明顯大於第一網點群102a的網點尺寸,導致第二網點群102b的網點太過密集(相鄰網點的間隙過小),如此於印刷網點時,網點容易連接在一起而產生糊版問題。 FIG. 4 is a schematic view showing the configuration of a dot structure of a conventional light guide plate. As shown in FIG. 4, the dot structure 102 is disposed on the bottom surface 104 of a light guide plate 100. The light incident surface 106 is adjacent to the light source 108. The bottom surface 104 includes a first region P adjacent to the light incident surface 106 of the light guide plate 100 and a distance from the light incident surface. A second region Q of 106, the dot structure 102 may include a first halftone group 102a distributed in the first region P and a second halftone cluster 102b distributed in the second region Q. As shown in the conventional design of FIG. 4, the spacing of two adjacent dots in all regions is generally set to be the same. For example, the dot spacing d1 of any two adjacent dots in the first dot group 102a is the same, and the dot spacing d1 is Equal to the dot spacing d2 of any two adjacent mesh points in the second halftone dot group 102b. However, as the optical path distance increases, the light energy is gradually attenuated, and the optical path is farther away (for example, the second region Q away from the light incident surface 106). The dot distribution density of the second dot group 102b is obviously larger than the dot size of the first dot group 102a, so that the dot of the second dot group 102b is too dense ( The gap between adjacent dots is too small. When printing dots, the dots are easily connected together to cause a paste problem.

The directional terms mentioned in the following embodiments, such as up, down, left, right, front or back, etc., are only directions referring to the additional drawings. Therefore, the directional terminology used is for the purpose of illustration and not limitation.
圖1為本發明一實施例的背光模組的示意圖。如圖1所示,背光模組1包含一導光板10以及一光源16,導光板10具有一入光面12及連接於入光面12並與入光面夾一角度的底面14,且入光面12鄰近例如發光二極體燈條的光源16。於本實施例中,底面14可包含不相重疊的一第一區域P及一第二區域Q,第一區域P例如可鄰近入光面12且第二區域Q遠離入光面12,且網點結構(未圖示)可設置於導光板10的底面14的第一區域P及第二區域Q中。 FIG. 1 is a schematic diagram of a backlight module according to an embodiment of the invention. As shown in FIG. 1 , the backlight module 1 includes a light guide plate 10 and a light source 16 . The light guide plate 10 has a light incident surface 12 and a bottom surface 14 connected to the light incident surface 12 and at an angle to the light incident surface. The glossy surface 12 is adjacent to a light source 16, such as a light emitting diode light strip. In this embodiment, the bottom surface 14 may include a first region P and a second region Q that do not overlap each other. The first region P may be adjacent to the light incident surface 12 and the second region Q is away from the light incident surface 12, and the dots A structure (not shown) may be disposed in the first region P and the second region Q of the bottom surface 14 of the light guide plate 10.
圖2A及圖2B為依本發明一實施例,顯示設置於導 光板底面的網點結構的配置形態示意圖。於本實施例中,網點結構包含圖2A所示的一預設網點圖案及圖2B所示的一實體網點結構,實體網點結構(圖2B)包含分佈於第一區域P的一第一網點群20a及分佈於第二區域Q的一第二網點群20b,預設網點圖案(圖2A)包含分佈於第一區域P的一第三網點群20c及分佈於第二區域Q的一第四網點群20d。首先請參考圖2A,於一預設網點圖案中,每兩相鄰網點的間距(例如第一區域P的間距值d1’及第二區域Q的間距值d2’)均相同,因隨著光程距離增加光能會逐漸衰減,故於光程較遠(即較遠離入光面12)的位置的網點尺寸可逐漸增大以滿足光學設計要求並提供較佳的輝度均勻性,兩相鄰網點的間隙C’會朝遠離入光面方向漸縮小。因此,預設網點圖案的第一區域P及第二區域Q可藉由每兩相鄰網點的間隙C’大小來劃分,當每兩相鄰網點C’的間隙大於一預設間隙(例如0.1mm)的區域屬於第一區域P,且每兩相鄰網點的間隙小於預設間隙(例如0.1mm)的區域屬於第二區域Q。如圖2A所示,於一實施例中,預設網點圖案的第三網點群20c及第四網點群20d可由複數個圓形網點T所構成,且在一垂直於入光面12的參考方向S上,複數個圓形網點T的直徑由導光板10的入光面12向導光板10相對於入光面12的一表面22的方向增加,且參考方向S上任兩個相鄰圓形網點T的網點間距d1’、d2’(兩個圓形網點T圓心的直線距離)均相同。 2A and 2B are diagrams showing a display according to an embodiment of the invention. Schematic diagram of the configuration of the dot structure on the bottom surface of the light panel. In this embodiment, the dot structure includes a preset dot pattern shown in FIG. 2A and a physical dot structure shown in FIG. 2B, and the physical dot structure (FIG. 2B) includes a first dot group distributed in the first region P. 20a and a second halftone dot group 20b distributed in the second region Q, the preset dot pattern (FIG. 2A) includes a third halftone dot group 20c distributed in the first region P and a fourth halftone dot distributed in the second region Q Group 20d. Referring to FIG. 2A, in a preset dot pattern, the spacing of each two adjacent dots (for example, the pitch value d1 of the first region P and the pitch value d2 of the second region Q) are the same, because with the light Increasing the optical energy of the path distance will gradually decay, so the dot size at the position where the optical path is farther away (ie, farther away from the light incident surface 12) can be gradually increased to meet the optical design requirements and provide better luminance uniformity, two adjacent The gap C' of the dot will gradually decrease toward the light entrance surface. Therefore, the first region P and the second region Q of the preset dot pattern can be divided by the size of the gap C′ of each two adjacent dots, when the gap between each two adjacent dots C′ is greater than a preset gap (for example, 0.1) The area of mm) belongs to the first area P, and the area where the gap of each two adjacent dots is smaller than the preset gap (for example, 0.1 mm) belongs to the second area Q. As shown in FIG. 2A, in an embodiment, the third halftone dot group 20c and the fourth halftone dot group 20d of the preset halftone dot pattern may be formed by a plurality of circular mesh dots T, and in a reference direction perpendicular to the light incident surface 12. In S, the diameter of the plurality of circular dots T is increased by the light incident surface 12 of the light guide plate 10 in the direction of the light guide 10 with respect to a surface 22 of the light incident surface 12, and any two adjacent circular dots T in the reference direction S The dot spacing d1', d2' (the linear distance of the two circular dots T center) are the same.
請再參考圖2B,本發明一實施例的實體網點結構包含分佈於第一區域P的一第一網點群20a及分佈於第二區域Q的一第二網點群20b,第二網點群20b的網點尺寸大於第一網點群20a的網點尺寸,如圖2B所示,實體網點結構的第一網點群20a及第二網點群20b亦可由複數個圓形網點T所構成,複數個圓形網點T的直徑同樣由導光板10的入光面12向導光板10相對於入光面12的一表面22的方向增加,且第二網點群20b的網點間距d2大於第一網點群 20a的網點間距d1。於本實施例中,同樣位於第一區域P的預設網點圖案的第三網點群20c與實體網點結構的第一網點群20a的網點分布相同,但同樣位於第二區域Q的實體網點結構的第二網點群20b與預設網點圖案的第四網點群20d的網點分布不同,如下以圖3A及圖3B說明兩者於第二區域Q的不同網點分布方式。導光板底面14的第二區域Q可畫分為多個單位區域,圖3A顯示預設網點圖案的第四網點群20d於單位區域下的網點分佈型態,圖3B顯示實體網點結構的第二網點群20b於單位區域下的網點分佈型態。比較圖3A及圖3B可知,於本實施例中,第二網點群20b單位區域M內的網點面積與單位區域M總面積的一面積比例與第四網點群20d在單位區域M內的網點面積與單位區域M總面積的一面積比例相同,亦即第二網點群20b與第四網點群20d具有相同的單位區域分佈密度,但第二網點群20b在單位區域M內的網點間距d2大於第四網點群20d的網點間距d2’,且第二網點群20b的網點尺寸大於單位區域M內的第四網點群20d的網點尺寸。依本發明實施例之設計,舉例而言,當網點群20b、20d均為圓形網點T所構成時,實體網點結構的第二網點群20b的平均圓形網點直徑(可為1.1962mm)大於預設網點圖案的第四網點群20d的平均圓形網點直徑(可為1.1857mm),第二網點群20b的網點間距d2(可為1.3362mm)大於第四網點群20d的網點間距d2’(可為1.2557mm),且第二網點群20b中兩相鄰網點產生的間隙C為0.14mm(>0.1mm)。因此,於本實施例中,分佈於第二區域Q的第二網點群20b雖然尺寸較大(1.1962mm>1.1857mm),但可藉由增大網點間距d2(1.3362mm>1.2557mm)獲得間隙C大於0.1mm的效果,故可在維持相同的網點分佈密度下避免於第二區域Q產生糊版情形。 Referring to FIG. 2B again, the physical dot structure of the embodiment of the present invention includes a first halftone dot group 20a distributed in the first region P and a second halftone dot group 20b distributed in the second region Q, and the second halftone dot group 20b. The dot size is larger than the dot size of the first dot group 20a. As shown in FIG. 2B, the first dot group 20a and the second dot group 20b of the physical dot structure may also be composed of a plurality of circular dots T, and a plurality of circular dots T The diameter of the light guide plate 10 is also increased by the light incident surface 12 of the light guide plate 10 relative to a surface 22 of the light incident surface 12, and the dot pitch d2 of the second mesh dot group 20b is greater than the first dot group. The dot spacing of 20a is d1. In this embodiment, the third halftone dot group 20c of the preset halftone dot pattern also located in the first region P has the same dot distribution as the first halftone dot group 20a of the physical dot structure, but is also located in the physical dot structure of the second region Q. The second halftone dot group 20b is different from the dot distribution of the fourth halftone dot group 20d of the preset halftone dot pattern. The different dot distribution patterns of the two second regions Q are described below with reference to FIGS. 3A and 3B. The second area Q of the bottom surface 14 of the light guide plate can be divided into a plurality of unit areas, FIG. 3A shows the distribution pattern of the fourth dot group 20d of the preset dot pattern in the unit area, and FIG. 3B shows the second structure of the physical dot structure. The dot distribution pattern of the dot group 20b under the unit area. 3A and 3B, in the present embodiment, an area ratio of the dot area in the unit area M of the second halftone dot group 20b to the total area of the unit area M and the dot area of the fourth halftone dot group 20d in the unit area M are known. The ratio of one area to the total area of the unit area M is the same, that is, the second halftone group 20b and the fourth halftone group 20d have the same unit area distribution density, but the second dot group 20b has a larger dot spacing d2 in the unit area M than the first The halftone dot group 20d has a dot pitch d2', and the dot size of the second halftone dot group 20b is larger than the halftone dot size of the fourth halftone dot group 20d in the unit region M. According to the design of the embodiment of the present invention, for example, when the mesh group 20b, 20d is composed of circular dots T, the average circular dot diameter (which may be 1.1962 mm) of the second halftone dot group 20b of the physical dot structure is greater than The average circular dot diameter (which may be 1.1857 mm) of the fourth halftone dot group 20d of the preset halftone dot pattern, the dot pitch d2 of the second halftone dot group 20b (which may be 1.3362 mm) is larger than the halftone dot spacing d2' of the fourth halftone dot group 20d ( It can be 1.2557 mm), and the gap C generated by two adjacent dots in the second halftone group 20b is 0.14 mm (>0.1 mm). Therefore, in the present embodiment, although the second halftone dot group 20b distributed in the second region Q has a large size (1.1962 mm>1.1857 mm), the gap can be obtained by increasing the dot pitch d2 (1.3362 mm>1.2557 mm). Since C has an effect of more than 0.1 mm, it is possible to avoid the occurrence of a paste in the second region Q while maintaining the same dot distribution density.
依上述各個實施例的設計,首先藉由設計一預設網點圖案,使光程不同的區域(例如第一區域P、第二區域Q)產生各自的網點分佈密度參考值,以符合光學設計要求並提供較佳的輝度均勻 性,如此當形成實體網點結構時,可依據預設網點圖案不同區域各自的網點分佈密度參考值,於維持與預設網點圖案相同的網點分佈密度前提下同時增大網點尺寸及網點間距,如此於網點印刷時,可避免網點連接在一起而不會產生糊版情形。 According to the design of each of the above embodiments, first, by designing a preset dot pattern, different regions of the optical path (for example, the first region P and the second region Q) are generated with respective dot distribution density reference values to meet optical design requirements. And provide better brightness uniformity Sex, when the physical dot structure is formed, the dot density and the dot spacing can be simultaneously increased according to the distribution density of the dot distribution in different regions of the preset dot pattern, while maintaining the same dot distribution density as the preset dot pattern. When printing at the dot, it is possible to avoid the dots being connected together without a paste.
惟以上所述者,僅為本發明之較佳實施例而已,當不能以此限定本發明實施之範圍,即大凡依本發明申請專利範圍及發明說明內容所作之簡單的等效變化與修飾,皆仍屬本發明專利涵蓋之範圍內。另外本發明的任一實施例或申請專利範圍不須達成本發明所揭露之全部目的或優點或特點。 The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
