Description
本新型提供一種導光板結構及其顯示裝置,特別是一種多層導光板結構及其顯示裝置。 The present invention provides a light guide plate structure and a display device thereof, in particular a multi-layer light guide plate structure and a display device thereof.
導光板是一種用於照明或顯示應用的薄型光學元件,其主要功能是將來自光源的光引導、均勻地分佈至其導光板表面,以實現照明設備的均勻照明效果或是顯示設備的均勻顯示效果。導光板一般應用在背光模組,例如液晶顯示器背光、LED平板燈、燈箱、指示燈等。 A light guide plate is a thin optical component used in lighting or display applications. Its main function is to guide the light from the light source and evenly distribute it to the surface of the light guide plate to achieve a uniform lighting effect for lighting equipment or a uniform display effect for display equipment. Light guide plates are generally used in backlight modules, such as LCD backlights, LED flat panel lights, light boxes, indicator lights, etc.
導光板的設計使其能夠在整個表面光導光源的輸出,以確保均勻亮度和光學性能。透過將表面紋理化或以特殊之方式處理,可確保光能在導光板內反射及折射,最終達成均勻照明的效果。一般為利用光學級的壓克力材料,諸如光學級的壓克力或PC板材,然後用具有極高折射率且不吸光的材料,在光學級的壓克力板材底面用例如雷射雕刻或網版印刷等以印上導光擴散點。藉此利用全反射的原理,當光線射到各個導光擴散點時,反射光會往各個角度擴散,然後利用疏密、尺寸不同的擴散點圖案設計來破壞光線的全反射,將光線導引至導光板正面,進而使導光板均勻發光。 The design of the light guide plate enables it to guide the output of the light source across the entire surface to ensure uniform brightness and optical performance. By texturing the surface or treating it in a special way, it can ensure that the light energy is reflected and refracted within the light guide plate, ultimately achieving a uniform lighting effect. Generally, optical grade acrylic materials, such as optical grade acrylic or PC sheets, are used, and then a material with an extremely high refractive index and no light absorption is used to print light diffusion points on the bottom surface of the optical grade acrylic sheet, such as laser engraving or screen printing. By using the principle of total reflection, when light hits each light guide diffusion point, the reflected light will diffuse to various angles, and then use the diffusion point pattern design with different density and size to destroy the total reflection of light, guide the light to the front of the light guide plate, and then make the light guide plate emit light evenly.
例如在LED照明中,導光板與LED光源的結合使其可以有效地利用LED的點光源,將光線引導到需要的區域,以提高能源效率並改善照明的 均勻性。這種技術在設計各種照明設備時都很常見,特別是在需要大面積均勻照明的場合。 For example, in LED lighting, the combination of light guide plates and LED light sources makes it possible to effectively utilize the point light source of LEDs to guide light to the required area to improve energy efficiency and improve lighting uniformity. This technology is common in the design of various lighting equipment, especially in situations where large areas need to be uniformly illuminated.
然而,一般的導光板通常僅提供顯示單一特定影像圖案,不具有顯示複數個影像圖案之功能。原因在於,即便提供了複數個顯示影像圖案,習知的導光板結構存在顯示不同層影像時,不同層影像間的圖案重疊而造成殘影,進而導致顯示不清的問題。為了解決這個問題,習知技術通常採用將顯示不同層影像間的圖案位置錯開,以避免不同層的圖案相互干擾。 However, a general light guide plate usually only provides a single specific image pattern for display, and does not have the function of displaying multiple image patterns. The reason is that even if multiple display image patterns are provided, the known light guide plate structure has the problem of overlapping patterns between different layers of images when displaying different layers of images, resulting in afterimages, which in turn leads to unclear display. To solve this problem, the known technology usually adopts the method of staggering the positions of the patterns between different layers of images to avoid interference between the patterns of different layers.
因此,如何提供一種能顯示不同層影像之不同圖案的多層導光板結構及其顯示裝置,同時不會存在不同層影像間殘影,亦不用刻意將不同層圖案的位置錯開的多層導光板結構及其顯示裝置,則至關重要。 Therefore, it is extremely important to provide a multi-layer light guide plate structure and a display device thereof that can display different patterns of different layers of images, and at the same time, there will be no afterimages between different layers of images, and there is no need to deliberately stagger the positions of different layers of patterns.
有鑑於此,本新型提供一種新穎之多層導光板結構及其顯示裝置,能有效解決不同層影像圖案殘影之問題。 In view of this, the present invention provides a novel multi-layer light guide plate structure and a display device thereof, which can effectively solve the problem of afterimages of different layers of image patterns.

本新型之一態樣提供一種多層導光板顯示裝置,包含:一燈盒,具有一底座及至少一側壁,底座及至少一側壁形成一容置空間;如前所述之多層導光板結構,設置於容置空間中;以及一玻璃面板,層疊於多層導光板結構相對於底座之另一面,其中,反射膜相鄰設置於底座,並且其中,半穿透半反射膜相鄰設置於玻璃面板。 One aspect of the present invention provides a multi-layer light guide plate display device, comprising: a light box having a base and at least one side wall, the base and at least one side wall forming a containing space; the multi-layer light guide plate structure as described above, disposed in the containing space; and a glass panel stacked on the other side of the multi-layer light guide plate structure opposite to the base, wherein the reflective film is disposed adjacent to the base, and wherein the semi-transmissive semi-reflective film is disposed adjacent to the glass panel.

That is, when the first light guide plate having the first display image and the second light guide plate having the different second display image receive the light source and guide the light to emit light, the partially overlapping first pattern and second pattern will not be displayed at the same time, and only the image of the light guide plate that receives the light source and guides the light to emit light will be displayed from the light emitting direction. In this way, the effect of displaying different images through multiple layers of light guide plates can be achieved, and at the same time, the images between each light guide plate will not interfere with each other or overlap or leave afterimages.

圖1顯示本新型一實施例中多層導光板顯示裝置之立體爆炸示意圖;圖2顯示本新型一實施例中多層導光板結構之層疊關係示意圖。 FIG1 shows a three-dimensional exploded schematic diagram of a multi-layer light guide plate display device in an embodiment of the present invention; FIG2 shows a schematic diagram of the stacking relationship of a multi-layer light guide plate structure in an embodiment of the present invention.
如圖1及圖2所示,本新型一實施例之多層導光板顯示裝置10包含多層導光板結構,所述多層導光板結構包含第一導光板100、第二導光板200、反射膜300、擴散膜400以及半穿透半反射膜500。 As shown in FIG. 1 and FIG. 2 , a multi-layer light guide plate display device 10 of an embodiment of the present invention includes a multi-layer light guide plate structure, wherein the multi-layer light guide plate structure includes a first light guide plate 100, a second light guide plate 200, a reflective film 300, a diffusion film 400, and a semi-transmissive semi-reflective film 500.
第一導光板100耦接於第一光源150,第二導光板200耦接於第二光源250。於本新型一實施例中,第一光源150及/或第二光源250可為LED燈條(Light bar),其LED顆粒可為但不限於白光、RGB,其LED顆粒尺寸亦可依需求調整其大小,此外,燈條及燈板之尺寸亦可依需求調整。 The first light guide plate 100 is coupled to the first light source 150, and the second light guide plate 200 is coupled to the second light source 250. In an embodiment of the present invention, the first light source 150 and/or the second light source 250 may be an LED light bar, and its LED particles may be but not limited to white light, RGB, and the size of its LED particles may also be adjusted according to needs. In addition, the size of the light bar and the light plate may also be adjusted according to needs.
反射膜300相鄰於第二導光板200層疊設置,並位於多層導光板結構的底部。 The reflective film 300 is stacked adjacent to the second light guide plate 200 and is located at the bottom of the multi-layer light guide plate structure.
擴散膜400設置於第一導光板100與第二導光板200之間,並與第一導光板100及第二導光板200相鄰層疊設置。 The diffusion film 400 is disposed between the first light guide plate 100 and the second light guide plate 200, and is stacked adjacent to the first light guide plate 100 and the second light guide plate 200.
半穿透半反射膜500相鄰於第一導光板100層疊設置,並位於多層導光板結構的頂部。 The semi-transmissive and semi-reflective film 500 is stacked adjacent to the first light guide plate 100 and is located at the top of the multi-layer light guide plate structure.
出光方向900為所述半穿透半反射膜500之平面法向量,遠離相鄰之第一導光板100之方向,意即,多層導光板結構之光由頂部之半穿透半反射膜500向外射出。 The light emitting direction 900 is the plane normal vector of the semi-transmissive and semi-reflective film 500, which is away from the direction of the adjacent first light guide plate 100, that is, the light of the multi-layer light guide plate structure is emitted outward from the semi-transmissive and semi-reflective film 500 at the top.
其中,於多層導光板結構之中,前述之第一導光板100、第二導光板200、反射膜300、擴散膜400及半穿透半反射膜500依照下列順序層疊依序設置排列:多層導光板結構頂部,即出光方向900;半穿透半反射膜500;第一導光板100;擴散膜400;第二導光板200;反射膜300;多層導光板結構底部。 Among them, in the multi-layer light guide plate structure, the aforementioned first light guide plate 100, second light guide plate 200, reflective film 300, diffusion film 400 and semi-transmissive semi-reflective film 500 are stacked and arranged in the following order: the top of the multi-layer light guide plate structure, i.e. the light emitting direction 900; semi-transmissive semi-reflective film 500; first light guide plate 100; diffusion film 400; second light guide plate 200; reflective film 300; bottom of the multi-layer light guide plate structure.
藉此,透過這樣的堆疊結構,藉由半穿透半反射膜500、擴散膜400、反射膜300互相影響、互相反射造成的結果,例如,由於半穿透半反射膜500具有鏡面效果,遇光才顯現光源影像,使其如外界鏡面玻璃一般的特性, 並可加強導光板網點輪廓的影像,並且由於中間層使用擴散膜400,因為擴散膜400有霧化的效果,可以避免第二導光板200的影像穿透於第一導光板100,此外,於背光結構中,反射膜300亦是底部的重要元件,可避免光發散,並將光源有效集中反射回出光面之出光方向900,以加強亮度及導光板網點顯現的特性。藉此,能夠達成個別清晰顯示第一導光板100或第二導光板200之影像之功效,而不會有不同層影像的互相抵觸干擾,也不會在顯示其中一層的影像時顯示不同層影像的殘影。 Thus, through such a stacking structure, the semi-transmissive and semi-reflective film 500, the diffusion film 400, and the reflective film 300 interact and reflect each other. For example, since the semi-transmissive and semi-reflective film 500 has a mirror effect, the image of the light source is displayed only when it encounters light, making it like the characteristics of external mirror glass. It can also enhance the image of the outline of the light guide plate dots. Since the diffusion film 400 is used as the middle layer, the diffusion film 400 has an atomization effect, which can prevent the image of the second light guide plate 200 from penetrating the first light guide plate 100. In addition, in the backlight structure, the reflective film 300 is also an important component at the bottom, which can prevent light from diverging and effectively concentrate the light source and reflect it back to the light exiting direction 900 of the light exiting surface to enhance the brightness and the characteristics of the light guide plate dots. In this way, the image of the first light guide plate 100 or the second light guide plate 200 can be displayed clearly separately without interference between different layers of images, and afterimages of different layers of images will not be displayed when displaying an image of one layer.
於本新型一實施例中,如圖1所示,多層導光板結構設置於多層導光板顯示裝置10之中,所述多層導光板顯示裝置10還包含容納多層導光板結構的燈盒(Light box)700以及覆蓋於頂部外側之玻璃面板(Glass)600。燈盒700具有底座及至少一側壁,底座及至少一側壁形成可以容納多層導光板結構的容置空間,並且其中,多層導光板結構以反射膜300與燈盒700底座相鄰設置,於本新型一實施例中,四個側壁由燈盒700底座四邊延伸。玻璃面板600層疊設置於多層導光板結構相對於燈盒700底座之另一面並與半穿透半反射膜500相鄰設置,即位於整個多層導光板顯示裝置10之最頂面,並且為多層導光板顯示裝置10之出光方向900。 In an embodiment of the present invention, as shown in FIG1 , a multi-layer light guide plate structure is disposed in a multi-layer light guide plate display device 10, and the multi-layer light guide plate display device 10 further includes a light box 700 for accommodating the multi-layer light guide plate structure and a glass panel 600 covering the outer side of the top. The light box 700 has a base and at least one side wall, and the base and at least one side wall form a receiving space for accommodating the multi-layer light guide plate structure, and wherein the multi-layer light guide plate structure is disposed adjacent to the base of the light box 700 with a reflective film 300. In an embodiment of the present invention, four side walls extend from four sides of the base of the light box 700. The glass panel 600 is stacked on the other side of the multi-layer light guide plate structure opposite to the base of the light box 700 and is adjacent to the semi-transmissive semi-reflective film 500, that is, it is located at the top surface of the entire multi-layer light guide plate display device 10 and is the light emitting direction 900 of the multi-layer light guide plate display device 10.
於本新型一實施例中,第一導光板100具有第一顯示影像,第二導光板200具有第二顯示影像,並且其中,第一顯示影像與第二顯示影像不相同。藉此,多層導光板結構可以顯示不同的影像內容,以具有更廣泛的實際應用性,以及適應於不同的使用場合。 In an embodiment of the present invention, the first light guide plate 100 has a first display image, the second light guide plate 200 has a second display image, and the first display image is different from the second display image. Thus, the multi-layer light guide plate structure can display different image contents, so as to have a wider practical applicability and be suitable for different usage scenarios.
於本新型一實施例中,第一光源150及第二光源250耦接於控制電路(圖未示),控制電路可為邏輯電路或由外部控制之電路,控制電路亦可為 控制器、處理器、微處理器、控制IC等得以控制切換第一光源150及第二光源250之電訊號之控制電路,控制電路適於選擇性地分別開關第一光源150及第二光源250。於本新型一實施例中,控制電路進一步適於控制第一光源150及/或第二光源250中的特定發光單元,例如不同顏色之LED燈粒或不同位置之LED燈粒等。 In an embodiment of the present invention, the first light source 150 and the second light source 250 are coupled to a control circuit (not shown). The control circuit may be a logic circuit or an externally controlled circuit. The control circuit may also be a control circuit for controlling the electrical signal of switching the first light source 150 and the second light source 250, such as a controller, a processor, a microprocessor, a control IC, etc. The control circuit is suitable for selectively switching the first light source 150 and the second light source 250, respectively. In an embodiment of the present invention, the control circuit is further suitable for controlling specific light-emitting units in the first light source 150 and/or the second light source 250, such as LED lamp grains of different colors or LED lamp grains in different positions, etc.
於本新型一實施例中,藉由所述之控制電路,得以透過分別開關第一光源150及第二光源250,用以於出光方向900分別顯示第一顯示影像或第二顯示影像,進而達成自動或手動之輸出顯示影像切換,以應用於不同的使用場合。 In an embodiment of the present invention, the control circuit can be used to switch the first light source 150 and the second light source 250 respectively to display the first display image or the second display image in the light output direction 900, thereby achieving automatic or manual output display image switching for application in different usage scenarios.
於本新型一實施例中,第一顯示影像具有第一圖案,第二顯示影像具有第二圖案,並且其中,第一圖案與第二圖案於出光方向900之投影方向部分重疊。即,不同層之第一導光板100與第二導光板200分別具有不同的顯示影像及其中的圖案,並且由出光方向900觀察其顯示影像時,其個別的顯示影像中之圖案,部分重疊於相同之位置,如後續圖3B、圖3C所示。藉此,大幅提升了導光板影像的實用性,由於不同層影像之間不會相互牴觸影響干擾,因此不同層的影像間的圖案可以自由設計並規劃其空間位置,而不用因殘影等因素讓位於其他層影像的圖案。 In an embodiment of the present invention, the first display image has a first pattern, the second display image has a second pattern, and the first pattern and the second pattern partially overlap in the projection direction of the light emitting direction 900. That is, the first light guide plate 100 and the second light guide plate 200 of different layers have different display images and patterns therein, and when the display images are observed from the light emitting direction 900, the patterns in the individual display images partially overlap at the same position, as shown in the subsequent Figures 3B and 3C. In this way, the practicality of the light guide plate image is greatly improved. Since the images of different layers will not interfere with each other, the patterns between the images of different layers can be freely designed and their spatial positions can be planned without giving way to the patterns of the images of other layers due to factors such as afterimages.
於本新型一實施例中,第一光源150及第二光源250於出光方向900之投影方向位於相異之兩側。即,第一光源150及第二光源250位於不同之位置,其可分置於多層導光板結構的天側、地側,以減少均放在同一側時光源本身空間占用及走線、電路板安排所需之空間,可使其結構更加薄型化。需注意的是,第一光源150及第二光源250的例如燈條及燈板等,並不限定其尺寸及 投光方式,其投光方式可為側投或直下式,並可因應實際燈盒之結構空間安排需求或導光板之結構而調整。 In an embodiment of the present invention, the first light source 150 and the second light source 250 are located on two different sides of the projection direction of the light emitting direction 900. That is, the first light source 150 and the second light source 250 are located at different positions, and they can be placed on the top side and the bottom side of the multi-layer light guide plate structure to reduce the space occupied by the light source itself and the space required for wiring and circuit board arrangement when they are all placed on the same side, so as to make the structure thinner. It should be noted that the first light source 150 and the second light source 250, such as light strips and light panels, are not limited in size and projection method. The projection method can be side projection or direct projection, and can be adjusted according to the structural space arrangement requirements of the actual light box or the structure of the light guide plate.

於本新型一實施例中,透過多層導光板結構前述之層疊結構,當多層導光板顯示裝置10未啟動時,其表面15可呈現清晰乾淨之鏡面效果,如圖3A所示。當多層導光板顯示裝置10啟動時,其呈現第一顯示影像11,如圖3B之示例性照片所示,可見其畫面左側具有充電訊號符號圖案,中間具有X5的雙圓圈圖案,右邊具有X10的雙圓圈圖案,且不會見到其他層的影像圖案;當切換其顯示影像時,其呈現第二顯示影像12,如圖3C之示例性照片所示,可見其 呈現了一組2x5之按鈕顯示介面,且不會見到如圖3B所示之其他層的影像圖案。同時,其影像圖案之位置可以重疊,而不需要設計彼此閃避的圖案。 In an embodiment of the present invention, through the aforementioned stacked structure of the multi-layer light guide plate structure, when the multi-layer light guide plate display device 10 is not activated, its surface 15 can present a clear and clean mirror effect, as shown in FIG3A. When the multi-layer light guide plate display device 10 is activated, it presents a first display image 11, as shown in the exemplary photo of FIG3B, it can be seen that the left side of the screen has a charging signal symbol pattern, the middle has a double circle pattern of X5, and the right side has a double circle pattern of X10, and the image patterns of other layers are not visible; when switching its display image, it presents a second display image 12, as shown in the exemplary photo of FIG3C, it can be seen that it presents a set of 2x5 button display interfaces, and the image patterns of other layers as shown in FIG3B are not visible. At the same time, the positions of its image patterns can overlap, without the need to design patterns that avoid each other.
於本新型一實施例中,前述之多層導光板結構或多層導光板顯示裝置可進一步整合於可透光之觸控面板中,藉以作為觸控式螢幕之影像發光背板,並可於多層導光板結構顯示例如觸控按鈕之影像及圖案,以應用於諸如遊戲機台、博弈機台之下注觸控面板等,並取代實體的按鍵按鈕。 In one embodiment of the present invention, the aforementioned multi-layer light guide plate structure or multi-layer light guide plate display device can be further integrated into a light-transmissive touch panel to serve as an image luminous backplane of a touch screen, and images and patterns such as touch buttons can be displayed on the multi-layer light guide plate structure, so as to be applied to the touch panel of a gaming machine or a gambling machine, and replace physical keys and buttons.
藉由本新型之多層導光板結構及多層導光板顯示裝置,透過半穿透半反射膜、第一導光板、擴散膜、第二導光板、反射膜的依序層疊設置,第一導光板與第二導光板之影像不會相互牴觸干擾,第一導光板與第二導光板的影像可分別切換顯示,而不會顯示另一導光板的疊加影像或殘影。亦即,具有第一顯示影像的第一導光板以及具有不同之第二顯示影像的第二導光板,其在各自接收到光源而導光發光時,其部分重疊之第一圖案與第二圖案不會同時顯示,僅有接收到光源而導光發光之導光板的影像會從出光方向顯示。藉此,達成可以透過多層導光板來顯示不同影像之效果,並同時具有各個導光板之間的影像均不會相互影響干擾或堆疊、殘影之功效。 By means of the multi-layer light guide plate structure and the multi-layer light guide plate display device of the present invention, through the sequential stacking of the semi-transmissive and semi-reflective film, the first light guide plate, the diffusion film, the second light guide plate, and the reflective film, the images of the first light guide plate and the second light guide plate will not interfere with each other, and the images of the first light guide plate and the second light guide plate can be switched and displayed respectively, without displaying the superimposed image or afterimage of the other light guide plate. That is, when the first light guide plate having the first display image and the second light guide plate having the different second display image receive the light source and guide the light to emit light, the partially overlapping first pattern and second pattern will not be displayed at the same time, and only the image of the light guide plate that receives the light source and guides the light to emit light will be displayed from the light emitting direction. In this way, the effect of displaying different images through multiple layers of light guide plates can be achieved, and at the same time, the images between each light guide plate will not interfere with each other or overlap or leave afterimages.
