Figure 4 is a schematic diagram of the shape and positional relationship between the light emitting unit 26, the light modulating layer 36 and the adhesive member 34 according to yet another embodiment of the present invention. In this embodiment, components with the same numbers as those in the previous embodiment have similar positions and functions, and therefore will not be described again.

綜上所述，本發明的背光模組及其發光鍵盤係利用膠合件之導光特性作為輔助照明，使發光單元正上方的按鍵字符具有充足照明。膠合件在燈前區域完全被調光層覆蓋，但是膠合件在燈後區域只有少部分被調光層覆蓋；或者膠合件在燈後區域完全沒有被調光層覆蓋。如此一來，無論發光單元位於導光模組的何處位置，發光按鍵之鍵帽的前後兩端都能有充足照明，使發光按鍵整體具有較佳的照明均勻性和光暈連續性。To sum up, the backlight module and its light-emitting keyboard of the present invention utilize the light-guiding properties of the glue as auxiliary lighting, so that the key characters directly above the light-emitting unit have sufficient illumination. The glued part is completely covered by the dimming layer in the area in front of the lamp, but only a small part of the glued part is covered by the dimming layer in the area behind the lamp; or the glued part is not covered by the dimming layer in the area behind the lamp at all. In this way, no matter where the light-emitting unit is located in the light guide module, the front and rear ends of the keycap of the light-emitting key can be fully illuminated, so that the overall light-emitting key has better illumination uniformity and halo continuity.

Each key 12 includes a keycap 24, a bottom plate 23, an elastic recovery member 20 and a lifting support mechanism 22 (only shown in Figure 6) connected between the keycap 24 and the bottom plate 23, as well as a The keycap 24 is pressed to generate a key signal from the film circuit board 16 (only shown in Figure 6). The film circuit board 16, the elastic recovery member 20 and the lifting support mechanism 22 can all be light-transmissive. The keys 12/keycaps 24 may have different shapes or sizes, such as square keys 12A (ie, single-sized keys), multi-sized keys 12B or other function keys. ). The keycap 24 may have one or more characters as the light-emitting area of the keycap 24, such as the main character A1 and the sub-character A2; some keys 12 do not have characters, such as the blank key (space) 12C keycap 24 in Figure 5 There is no light emitting area. In addition to characters serving as light-emitting areas, the four sides of the keycap 24 of each key 12 can also emit light, allowing the user to see a rectangular halo to identify the boundaries of the key 12/keycap 24 . The bottom plate 23 has a frame 231a, a plurality of bridge ribs 231b and annular ribs 231c. The plurality of bridge ribs 231b are respectively connected between the annular rib 231c and the frame 231a, and define a plurality of light-transmissive side holes 232b and inner holes 232c.
參考第5/6/7圖，背光模組18設置在複數按鍵12的下方，包括光源電路板14、導光板30和透光膜32。發光鍵盤10上每個按鍵12/鍵帽24下方對應光源電路板14上的至少一個發光單元26。為控制背光模組18的出光位置與面積，透光膜32包括透光區320、光學塊321和光學框322；其中光學塊321鄰近鍵帽24(或其投影)的中央區域，光學框322則圍繞在鍵帽24的輪廓區域內外側，而透光區320圍繞著光學塊321，且透光區320位於光學塊321和光學框322之間。如同前述實施例介紹的調光層36，位在發光單元26正上方的光學塊321可包括遮光塊321b(例如深色或黑色塗層)和反射塊321w(例如白色或含金屬塗層)，遮光塊321b吸光或不透光，反射塊321w則部分透光、部分反光或完全反光(高反射率意味著低透光率)。光學框322也和前述調光層36類似，包括遮光框322b(例如深色或黑色塗層)和反射框322w(例如白色或含金屬塗層)。光學框322的孔徑定義透光區320的外邊界，也可用於控制鍵帽24四周光暈的出光量；光學塊321的外徑則定義透光區320的內邊界，發光單元26的光線必須向外橫向傳遞到超出遮光塊321b之外才有機會局部出光，或者光線繼續向外傳遞到超出反射塊321w，就能通過透光區320充分出光。在其他實施例中，特別是發光單元26採用彩色或多色光源時，光學塊321可以包括可透光的色塊，針對發光均勻度及/或混光效果進行調整。Referring to Figure 5/6/7, the backlight module 18 is disposed below the plurality of buttons 12 and includes a light source circuit board 14, a light guide plate 30 and a light-transmitting film 32. The bottom of each key 12/keycap 24 on the light-emitting keyboard 10 corresponds to at least one light-emitting unit 26 on the light source circuit board 14. In order to control the light emitting position and area of the backlight module 18, the light-transmitting film 32 includes a light-transmitting area 320, an optical block 321 and an optical frame 322; the optical block 321 is adjacent to the central area of the keycap 24 (or its projection), and the optical frame 322 It surrounds the inner and outer sides of the outline area of the keycap 24 , and the light-transmitting area 320 surrounds the optical block 321 , and the light-transmitting area 320 is located between the optical block 321 and the optical frame 322 . Like the dimming layer 36 introduced in the previous embodiment, the optical block 321 located directly above the light-emitting unit 26 may include a light-shielding block 321b (such as a dark or black coating) and a reflective block 321w (such as a white or metallic coating). The light-shielding block 321b absorbs light or is opaque, while the reflective block 321w is partially light-transmitting, partially reflective, or completely reflective (high reflectivity means low light transmittance). The optical frame 322 is also similar to the aforementioned light modulation layer 36 and includes a light-shielding frame 322b (eg, dark or black coating) and a reflective frame 322w (eg, white or metal-containing coating). The aperture of the optical frame 322 defines the outer boundary of the light-transmitting area 320, and can also be used to control the amount of light emitted by the halo around the keycap 24; the outer diameter of the optical block 321 defines the inner boundary of the light-transmitting area 320, and the light from the light-emitting unit 26 must Only when the light is transmitted laterally outward beyond the light-shielding block 321b can partial light be emitted, or the light can be fully emitted through the light-transmitting area 320 if the light continues to be transmitted outward beyond the reflective block 321w. In other embodiments, especially when the light-emitting unit 26 uses a colored or multi-colored light source, the optical block 321 may include a light-transmissive color block to adjust the uniformity of light emission and/or the light mixing effect.
參考第5/6/7圖，導光板30位於光學膜32與光源電路板14之間，詳細而言導光板30位在光學膜32的反射塊321w與反射框322w、以及光源電路板14的反射層142之間，如此可以盡可能回收光線到導光板30。當發光單元26採用發光功率較低的mini LED或micro LED時，光線的有效回收與橫向傳遞更為重要。導光板30的上表面或下表面可設置微光學層31a導引光線向上擴散出光，微光學層31a的組成可以是複數微細光學件(如金屬漆或白漆)構成的微圖案、或是凹凸微結構構成的微圖案，且俯視或剖視下微圖案的每一個體可能是微點、微線或任意形狀。微光學層31a通常對應佈設在可透光的區域下方，例如光學膜32的透光區320和底板23的複數邊孔232b和內孔232c。就回收光線與導引光線功能而言，類似設計可以設置在光源電路板14的反射層142上，例如微光學層31b。原則上微光學層31與微光學層31b是平行導光板30和光源電路板14設置，且微光學層31與微光學層31b可以擇一設置或同時設置而有加乘效果，微光學層31與微光學層31b也可以設置在不出光的位置，例如微光學層31與微光學層31b與底板23的邊框231a、複數橋肋231b和環肋231c重疊時，可以加強回收與擴散光線的效果，使更多光線到達透光區320/鍵帽24的側邊或角落位置。Referring to Figure 5/6/7, the light guide plate 30 is located between the optical film 32 and the light source circuit board 14. Specifically, the light guide plate 30 is located between the reflective block 321w and the reflective frame 322w of the optical film 32, and the light source circuit board 14. between the reflective layers 142, so that light can be recovered to the light guide plate 30 as much as possible. When the light-emitting unit 26 uses mini LED or micro LED with lower luminous power, effective recovery and lateral transmission of light are more important. A micro-optical layer 31a can be provided on the upper or lower surface of the light guide plate 30 to guide light to diffuse upward. The micro-optical layer 31a can be composed of a micro-pattern composed of a plurality of fine optical components (such as metallic paint or white paint), or a concave and convex surface. A micropattern composed of microstructures, and each entity of the micropattern may be a microdot, a microline, or any shape when viewed from above or in cross section. The micro-optical layer 31a is usually arranged correspondingly under the light-transmissive area, such as the light-transmitting area 320 of the optical film 32 and the plurality of side holes 232b and inner holes 232c of the base plate 23. In terms of light recycling and light guiding functions, similar designs can be provided on the reflective layer 142 of the light source circuit board 14, such as the micro-optical layer 31b. In principle, the micro-optical layer 31 and the micro-optical layer 31b are arranged parallel to the light guide plate 30 and the light source circuit board 14, and the micro-optical layer 31 and the micro-optical layer 31b can be arranged selectively or simultaneously to have a synergistic effect. The micro-optical layer 31 The micro-optical layer 31b can also be arranged in a position where no light is emitted. For example, when the micro-optical layer 31 and the micro-optical layer 31b overlap with the frame 231a, plural bridge ribs 231b and ring ribs 231c of the bottom plate 23, the effect of recovering and diffusing light can be enhanced. , allowing more light to reach the side or corner positions of the light-transmitting area 320/keycap 24.
參考第6/8/9圖，光源電路板14由基層140、光源電路141與反射層142構成，光源電路141位於反射層142與基層140之間，發光單元26電性連接光源電路板14及其光源電路141，且發光單元26凸出於反射層142之上。光源電路板14和其光源電路141可以是對應發光鍵盤10整體尺寸的電路板，或者僅是狹長條狀的軟性電路板。不論光源電路板14的尺寸為何，反射層142和其上方的導光板30及透明膜32的大小都是對應發光鍵盤10的整體尺寸。為避免材料在製程或使用環境下的熱漲冷縮，或者降低光源電路板14對系統射頻訊號的干擾，基層140可以採用金屬基板，此時可加上間隔層143在光源電路141與基層140之間，確保光源電路141正常運作。參考第9圖，光源電路141可能更包含銅網Cm (cupper mesh)以提供結構剛性、或提供射頻屏蔽，銅網Cm的存在會使反射層142表面出現微光學層31b；即使在沒有銅網Cm的實作中，微光學層31b可以透過反光成分粒子尺寸的控制，形成導引光線的擴散光點。光源電路141可以包括一對高壓/低壓主導線141a，透過一對子導線141b電性連接發光單元26。除了第8圖位在發光單元26與入光孔31附近的核微圖案cMP1/cMP2之外，在按鍵12/鍵帽24投影範圍內，主導線141a與子導線141b將微光學層31b切割為一對微圖案oMP與一對微圖案iMP。在此最佳化配置下，無膠環區54B、膠合件34及其主膠體54/子膠體56/缺口54A，都位在一對微圖案oMP之間；同時無膠環區54B、膠合件34及其主膠體54/子膠體56/缺口54A，也都位在一對微圖案iMP之間。換言之，也可說是一對分離的微圖案oMP位在該發光單元26兩側，或者一對分離的微圖案iMP位在該發光單元26兩側。Referring to Figure 6/8/9, the light source circuit board 14 is composed of a base layer 140, a light source circuit 141 and a reflective layer 142. The light source circuit 141 is located between the reflective layer 142 and the base layer 140. The light emitting unit 26 is electrically connected to the light source circuit board 14 and The light source circuit 141 and the light emitting unit 26 protrude above the reflective layer 142 . The light source circuit board 14 and its light source circuit 141 may be a circuit board corresponding to the overall size of the luminous keyboard 10 , or may be only a long and narrow flexible circuit board. Regardless of the size of the light source circuit board 14 , the size of the reflective layer 142 , the light guide plate 30 and the transparent film 32 above it all correspond to the overall size of the luminous keyboard 10 . In order to avoid thermal expansion and contraction of materials during the manufacturing process or use environment, or to reduce the interference of the light source circuit board 14 on the system's radio frequency signal, the base layer 140 can be a metal substrate. In this case, a spacer layer 143 can be added between the light source circuit 141 and the base layer 140 to ensure that the light source circuit 141 operates normally. Referring to Figure 9, the light source circuit 141 may further include a copper mesh Cm (cupper mesh) to provide structural rigidity or provide radio frequency shielding. The existence of the copper mesh Cm will cause a micro-optical layer 31b to appear on the surface of the reflective layer 142; even without the copper mesh In the implementation of Cm, the micro-optical layer 31b can form a diffuse light spot that guides light by controlling the particle size of the reflective component. The light source circuit 141 may include a pair of high-voltage/low-voltage main wires 141a, electrically connected to the light-emitting unit 26 through a pair of sub-wires 141b. In addition to the core micro-pattern cMP1/cMP2 near the light-emitting unit 26 and the light entrance hole 31 in the eighth image, within the projection range of the key 12/keycap 24, the main wire 141a and the sub-wire 141b cut the micro-optical layer 31b into A pair of micropatterned oMPs and a pair of micropatterned iMPs. Under this optimized configuration, the glue-free ring area 54B, the glued parts 34 and their main colloid 54/sub-colloid 56/notch 54A are all located between a pair of micro-pattern oMPs; at the same time, the glue-free ring area 54B, the glued parts 34 and its main colloid 54/sub-colloid 56/notch 54A are also located between a pair of micro-pattern iMPs. In other words, it can also be said that a pair of separated micro-patterns oMP are located on both sides of the light-emitting unit 26 , or a pair of separated micro-patterns iMP are located on both sides of the light-emitting unit 26 .

At this time, the distance Tc between the glue-free area 54B and the main wire 141a on the connection line C is greater than the distance Ta between the notch 54A and the main wire 141a on the connection C; and the glue-free area 54B and the connection C The distance Tc between the main wires 141a on the connection line C is greater than the distance Tb between the sub-colloid 56 and the main wires 141a on the connection line C. In addition, the distance Tb between the sub-colloid 56 and the main wire 141a on the connection line C is also greater than the distance Ta between the main colloid 54 and the main wire 141a on the connection line C. Therefore, under the optimal configuration of the present invention, on a connection line C passing through the light-emitting element 26, the glue-free area 54B, the glue member 34 and the main wire 141a, the glue-free area 54B and the main line C on the connection C The distance Tc between the lines 141a is greater than the distance T between the adhesive member 34 and the main wire 141a on the connection line C.
參考第6/7/8/9圖，導光板30入光孔31通常開設較小尺寸，避免過多光線在進入入光孔31前的不必要逸散，可採用膠合件52確保發光單元26與入光孔31維持固定相對距離。膠合件52也可選擇性設置在透光膜32與導光板30之間，不過透光膜32與導光板30之間可以只設置膠材在對應按鍵12間隙處，或膠材只設置在整片透光膜32的外周緣。如前述實施例說明，可透光的膠合件34可以用於光線調整。膠合件34可包括主膠體54(即第一膠體)與子膠體56(即第二膠體)。Referring to Figures 6/7/8/9, the light entrance hole 31 of the light guide plate 30 is usually of a smaller size to avoid unnecessary escape of too much light before entering the light entrance hole 31. The glue piece 52 can be used to ensure that the light emitting unit 26 is connected to the light entrance hole 31. The light entrance holes 31 maintain a fixed relative distance. The glue piece 52 can also be selectively disposed between the light-transmitting film 32 and the light guide plate 30. However, the glue material can only be provided between the light-transmitting film 32 and the light guide plate 30 at the gap corresponding to the button 12, or the glue material can only be provided throughout the gap. the outer peripheral edge of the light-transmitting film 32. As explained in the previous embodiments, the light-transmissive glue 34 can be used for light adjustment. The glue piece 34 may include a main colloid 54 (ie, the first colloid) and a sub-colloid 56 (ie, the second colloid).
主膠體54為環形膠體，主膠體54同時環繞導光板30之入光孔31和入光孔31中的發光單元26；子膠體56為至少局部向外延伸的膠塊，子膠體56較主膠體54遠離入光孔31也遠離發光單元26。主膠體54可以具有缺口54A，而子膠體56鄰近缺口54A設置；缺口54A和子膠體56都可以是任意形狀，並不需要完全對應；子膠體56可以完全脫離主膠體54外徑範圍，或者局部與主膠體54相連，或者完全與主膠體54相連(缺口54A僅是一個凹口)。在一些實施例中，主膠體54與子膠體56可以位在導光板30的不同表面。由於膠合件34是良好的光通道，光線可以輕易穿出或穿入導光板30表面，但因膠合件34相當接近發光單元26，這意味著可能有部分光線會在膠合件34處頻繁上下進出導光板30造成傳遞損耗；相較之下，缺口54A和外移的子膠體56容許較多光線橫向傳遞，因此可以沿著發光單元26到缺口54A/子膠體56延伸直線附近提供較多光線，適合用於不易被照亮的外圍字符，例如子字符A2。在前述優化的設計下，為確保子膠體56所在方位的光線充足並提升背光均勻度，子膠體56與子字符A2的距離Da小於母膠體54到子字符A2的距離Db；類似的，子膠體56與透明膜32光學框322內緣(不論是遮光框322b或反射框322w)的距離，小於母膠體54到光學框322內緣的距離。The main colloid 54 is an annular colloid, and the main colloid 54 surrounds the light entrance hole 31 of the light guide plate 30 and the light-emitting unit 26 in the light entrance hole 31 at the same time; the sub-colloid 56 is a block of glue that at least partially extends outward, and the sub-colloid 56 is smaller than the main colloid. 54 is away from the light entrance hole 31 and away from the light emitting unit 26 . The main colloid 54 can have a notch 54A, and the sub-colloid 56 is arranged adjacent to the notch 54A; the notch 54A and the sub-colloid 56 can be in any shape and do not need to correspond exactly; the sub-colloid 56 can be completely separated from the outer diameter range of the main colloid 54, or partially aligned with the outer diameter range of the main colloid 54. The main colloid 54 is connected, or completely connected with the main colloid 54 (the notch 54A is just a notch). In some embodiments, the main colloid 54 and the sub-colloid 56 may be located on different surfaces of the light guide plate 30 . Since the glued part 34 is a good light channel, light can easily pass through or into the surface of the light guide plate 30 . However, because the glued part 34 is quite close to the light emitting unit 26 , this means that some light may frequently pass up and down the glued part 34 . The light guide plate 30 causes transmission loss; in comparison, the notch 54A and the outwardly moved sub-colloid 56 allow more light to be transmitted laterally, so more light can be provided near the straight line extending from the light-emitting unit 26 to the notch 54A/sub-colloid 56. Suitable for peripheral characters that are difficult to illuminate, such as sub-character A2. Under the aforementioned optimized design, in order to ensure sufficient light in the direction of the sub-colloid 56 and improve backlight uniformity, the distance Da between the sub-colloid 56 and the sub-character A2 is smaller than the distance Db from the parent colloid 54 to the sub-character A2; similarly, the distance Da between the sub-colloid 56 and the sub-character A2 is smaller than the distance Db between the sub-colloid 54 and the sub-character A2; similarly, The distance between 56 and the inner edge of the optical frame 322 of the transparent film 32 (whether it is the light-shielding frame 322b or the reflective frame 322w) is smaller than the distance between the master colloid 54 and the inner edge of the optical frame 322.
參考第7/8圖，膠合件34和導光板30入光孔31之間留有無膠環區54B環繞著入光孔31，如此可以避免膠合件34在印刷製程中偏移或溢流以致黏上發光單元26，造成出光條件改變或發光單元26脫落(失去與光源電路141電性連接)，因此無膠環區54B存在於母膠體54與入光孔31之間，也位在子膠體56與入光孔31之間就有其必要性。如此一來，子膠體56與透明膜32光學框322內緣(不論是遮光框322b或反射框322w)的距離，將小於無膠環區54B到光學框322內緣的距離；其意義等同於子膠體56和主膠體54缺口54A的配置，是接近並指向需要提升字符亮度或光暈均勻度的方位。換言之，發光單元26、主膠體54缺口54A和外圍字符(子字符A2)三者的正投影位在一直線上；由於子膠體56與母膠體54的缺口54A的位置相近，因此也可說發光單元26、子膠體56和外圍字符(子字符A2)三者的正投影位在一直線上。不過，若同時考量到外圍字符鄰近區域的鍵帽24光暈，缺口54A的大小也可用於微調光線傳遞角度；因此，也可說是外圍字符(和其投影)會設置在發光單元26與缺口54A延伸的扇形區域V內(見第10A圖)，或說外圍字符會與該扇形區域V至少局部的重疊；當然，孔道Hx或說導光板30的緣牆31a最好不在發光單元26與缺口54A延伸的扇形區域V內，以避免嚴重漏光。再者，在不同實施例中，無膠環區54B可以位在導光板30的上表面及/或下表面。Referring to Figure 7/8, there is a glue-free ring area 54B between the glued part 34 and the light entrance hole 31 of the light guide plate 30 surrounding the light entrance hole 31. This can prevent the glued part 34 from being offset or overflowing during the printing process and causing sticking. If the light emitting unit 26 is placed on the light emitting unit 26, the light emitting condition changes or the light emitting unit 26 falls off (loses electrical connection with the light source circuit 141). Therefore, the glue-free ring area 54B exists between the mother colloid 54 and the light entrance hole 31, and is also located between the sub-colloid 56 and the light entrance hole 31 is necessary. In this way, the distance between the sub-colloid 56 and the inner edge of the optical frame 322 of the transparent film 32 (whether it is the light-shielding frame 322b or the reflective frame 322w) will be smaller than the distance from the glue-free ring area 54B to the inner edge of the optical frame 322; its meaning is equivalent to The configuration of the notch 54A of the sub-colloid 56 and the main colloid 54 is close to and pointed at the direction where character brightness or halo uniformity needs to be improved. In other words, the orthographic projections of the light-emitting unit 26, the notch 54A of the main colloid 54 and the peripheral character (sub-character A2) are on a straight line; since the positions of the sub-colloid 56 and the notch 54A of the mother colloid 54 are close to each other, it can also be said that the light-emitting unit 26. The orthographic projections of the sub-colloid 56 and the peripheral character (sub-character A2) are on a straight line. However, if the halo of the keycap 24 in the vicinity of the peripheral characters is also taken into consideration, the size of the notch 54A can also be used to fine-tune the light transmission angle; therefore, it can also be said that the peripheral characters (and their projections) will be disposed between the light-emitting unit 26 and the notch 54A extends within the fan-shaped area V (see Figure 10A), or the peripheral characters will at least partially overlap with the fan-shaped area V; of course, the hole Hx or the edge wall 31a of the light guide plate 30 is preferably not between the light-emitting unit 26 and the gap 54A extends within the fan-shaped area V to avoid serious light leakage. Furthermore, in different embodiments, the plastic ring-free area 54B may be located on the upper surface and/or the lower surface of the light guide plate 30 .
參考第7/8圖，在實際生產過程中，因為透光膜32的光學塊321透光度太低(如反光塊321w厚度過厚、或者反光成分濃度過高)，有可能導致發光單元26正上方出光不足、使附近的(第一)字符A1亮度不足。此時增加出光亮度的手段之一，是增加導光板30入光孔31周圍區域的出光量，於是前述微光學層31a/31b可佈設於入光孔31周圍區域。例如第8圖中，微光學層31a及/或31b具有環狀核微圖案cMP1和矩形核微圖案cMP2重疊透光膜32的光學塊321和膠合件34。環狀核微圖案cMP1環繞入光孔31和發光單元26，且光學塊321及/或環狀核微圖案cMP1可以至少局部重疊無膠環區54B、主膠區54、遮光塊321b和反光塊321w其中之一或其任意組合。由於反光塊321w可以局部透光，核微圖案cMP1超出遮光塊321b的面積越多，越能提高向上出光。矩形核微圖案cMP2可以至少局部重疊主膠體54的缺口54A和子膠體56其中一個，或同時重疊二者。由於缺口54A的橫向光線傳遞較多，矩形核微圖案cMP2的密度可能需要大於環狀核微圖案cMP1，才能提供較佳的出光均勻度。作為調和缺口54A過亮的手段，無膠環區54B和缺口54A範圍內也可能設置無微點區54C，無微點區54C可說位於膠合件34與入光孔31之間；在核微圖案cMP1及/或cMP2存在的前提下，如此可以局部地不增加無微點區54C所在位置的出光量。Referring to Figure 7/8, in the actual production process, because the light transmittance of the optical block 321 of the light-transmitting film 32 is too low (such as the thickness of the reflective block 321w is too thick, or the concentration of the reflective component is too high), it may cause the light-emitting unit 26 to The light directly above is insufficient, resulting in insufficient brightness of the nearby (first) character A1. At this time, one of the means to increase the brightness of the light is to increase the amount of light in the area around the light entrance hole 31 of the light guide plate 30 , so the aforementioned micro-optical layer 31 a / 31 b can be arranged in the area around the light entrance hole 31 . For example, in FIG. 8 , the micro-optical layers 31 a and/or 31 b have an annular core micro-pattern cMP1 and a rectangular core micro-pattern cMP2 overlapping the optical block 321 and the glue 34 of the light-transmitting film 32 . The annular core micro-pattern cMP1 surrounds the light entrance 31 and the light-emitting unit 26, and the optical block 321 and/or the annular core micro-pattern cMP1 can at least partially overlap the glue-free ring area 54B, the main glue area 54, the light-shielding block 321b and the reflective block. One of 321w or any combination thereof. Since the reflective block 321w can partially transmit light, the larger the area of the core micro-pattern cMP1 beyond the light-shielding block 321b, the more upward light emission can be improved. The rectangular core micropattern cMP2 may at least partially overlap one of the gaps 54A of the main colloid 54 and the sub-colloid 56, or overlap both at the same time. Since the gap 54A transmits more lateral light, the density of the rectangular core micropattern cMP2 may need to be greater than the annular core micropattern cMP1 in order to provide better light uniformity. As a means of adjusting the over-brightness of the notch 54A, a micro-dot-free area 54C may also be provided within the glue ring-free area 54B and the notch 54A. The micro-dot-free area 54C can be said to be located between the glued part 34 and the light entrance hole 31; Under the premise that the patterns cMP1 and/or cMP2 exist, the amount of light emitted at the location of the micro-dot-free area 54C can not be locally increased.
參閱第5/6/7/8/9圖，發光鍵盤10上的任意按鍵12周圍、甚至按鍵12的鍵帽24投影範圍內，可能設置有孔道Hx貫穿發光鍵盤10及其背光模組18；孔道Hx可能作為電腦系統的散熱孔，或作為固定發光鍵盤10及其背光模組18的組裝結構孔。孔道Hx是由發光鍵盤10及其背光模組18各層的透孔所組成；詳言之，孔道Hx從上而下一路貫穿薄膜電路板16、底板23、透光膜32、導光板30以及反射層142和光源電路板14。如前所述，子膠體56和缺口54A所在方位將會有較多光線橫向傳遞(經由導光板30中全反射傳遞)，而孔道Hx處的導光板30的緣牆31a卻是會漏光的。因此為避免漏光，發光元件26、缺口54A和孔道Hx必須不位在一直線上，或者說發光元件26、子膠體56和孔道Hx不位在一直線上。簡言之，缺口54A、子膠體56不朝向孔道Hx就可相當程度減少可從孔道Hx漏光的光量。在此優化配置之下，無膠環區54B與導光板30截面的緣牆31a的間距，大於膠合件34與導光板30緣牆31a的間距，而且不論可漏光的緣牆31a實質是位於導光板30封閉的貫孔、導光板30平直邊緣半開放的半孔、或是導光板30外側的平直邊牆皆是如此。本發明雖然透過上述和以下實施例可以清楚明瞭的說明設計方案與技術原理，但是這些優化設計並非是輕易置換的設計選擇，因為發明人經過數個世代產品機種的設計驗證、原型驗證、試產修正、量產修正，才能得到這些研究成果。Referring to Figures 5/6/7/8/9, around any key 12 on the luminous keyboard 10, or even within the projection range of the keycap 24 of the key 12, there may be a hole Hx that penetrates the luminous keyboard 10 and its backlight module 18; The hole Hx may be used as a heat dissipation hole of the computer system, or as an assembly structural hole for fixing the luminous keyboard 10 and its backlight module 18 . The hole Hx is composed of the through holes of each layer of the luminous keyboard 10 and its backlight module 18; specifically, the hole Hx runs through the thin film circuit board 16, the bottom plate 23, the light-transmitting film 32, the light guide plate 30 and the reflective film from top to bottom. layer 142 and light source circuit board 14. As mentioned above, more light will be transmitted laterally (transmitted through total reflection in the light guide plate 30) at the location of the sub-colloid 56 and the notch 54A, but the edge wall 31a of the light guide plate 30 at the hole Hx will leak light. Therefore, in order to avoid light leakage, the light-emitting element 26, the notch 54A and the hole Hx must not be located in a straight line, or that the light-emitting element 26, the sub-colloid 56 and the hole Hx must not be located in a straight line. In short, if the gap 54A and the sub-colloid 56 do not face the hole Hx, the amount of light that can leak from the hole Hx can be reduced to a considerable extent. Under this optimized configuration, the distance between the glue-free ring area 54B and the edge wall 31a of the light guide plate 30 is greater than the distance between the adhesive member 34 and the edge wall 31a of the light guide plate 30, and regardless of whether the edge wall 31a that can leak light is actually located on the guide This is true for the closed through hole of the light plate 30 , the semi-open half hole on the straight edge of the light guide plate 30 , or the straight side wall outside the light guide plate 30 . Although the design scheme and technical principles of the present invention can be clearly explained through the above and following embodiments, these optimized designs are not easily replaceable design choices because the inventor has gone through design verification, prototype verification, and trial production of several generations of product models. Only through correction and mass production correction can these research results be obtained.
需要強調的是，鍵帽24的字符通常和透明膜32的透光區320重疊，以便背光模組18出光的光線可以照射字符，不過字符也經常被其他元件/結構遮住，或者因應外觀設計出現特殊相對位置與背光問題，此時需要不同手段搭配應對。第7圖中，主字符A1與光學塊321重疊，因此實作中可能會有幾種手段增加出光量，例如加開或增大底板23的內孔232c、光學塊321上打孔(如第5圖透光網點361)、縮小遮擋塊321b、減薄光學塊321或反光塊321w厚度等等方法來提高光學塊321的透光率；或者，對應字符佈設微光學層31a/31b、提高微光學層31a/31b密度、加寬膠合件34的寬度、增加膠合件34面積等，來提高LED上方和鄰近問題區域的出光量。第7圖中，子字符A2的困境除了距離發光單元26較遠之外，子字符A2重疊了底板23的橋肋231b，此時可以增加缺口54A的寬度/面積、提高子字符A2附近的兩個邊孔232b對應的微光學層31a/31b的密度、外推子膠體56(使子膠體56距離發光單元26更遠)。此外，因缺口54A具有一定寬度，並且光線向外傳遞具有一定的擴散角度，即使底板23上並沒有垂直對應子字符A2的開孔，也能透過子字符A2附近的兩個邊孔232b照亮子字符A2。It should be emphasized that the characters of the keycap 24 usually overlap with the light-transmitting area 320 of the transparent film 32 so that the light from the backlight module 18 can illuminate the characters. However, the characters are often blocked by other components/structures or due to appearance design. When special relative position and backlight problems arise, different methods are needed to deal with them. In Figure 7, the main character A1 overlaps with the optical block 321. Therefore, there may be several methods to increase the light output in practice, such as opening or enlarging the inner hole 232c of the base plate 23, drilling holes in the optical block 321 (as shown in Figure 7). 5 light-transmitting dots 361), reducing the blocking block 321b, thinning the optical block 321 or the thickness of the reflective block 321w, etc. to improve the light transmittance of the optical block 321; or, arrange the micro-optical layer 31a/31b corresponding to the characters to improve the micro- The density of the optical layer 31a/31b, widening the width of the glue piece 34, increasing the area of the glue piece 34, etc., can increase the amount of light emitted above the LED and adjacent to the problem area. In Figure 7, the predicament of sub-character A2 is not only far from the light-emitting unit 26, but also overlaps the bridge rib 231b of the bottom plate 23. At this time, the width/area of the notch 54A can be increased, and the two sides near the sub-character A2 can be improved. The density of the micro-optical layer 31a/31b corresponding to each side hole 232b is extrapolated to the sub-colloid 56 (making the sub-colloid 56 further away from the light-emitting unit 26). In addition, since the notch 54A has a certain width and the light has a certain diffusion angle when transmitted outward, even if there is no opening vertically corresponding to the sub-character A2 on the base plate 23, it can still be illuminated through the two side holes 232b near the sub-character A2. Subcharacter A2.
參閱第10A/10B圖，第10A圖為本發明另一實施例的發光鍵盤10在單顆按鍵12範圍的局部疊合示意圖；第10B圖為本發明再一實施例的發光鍵盤10在單顆按鍵12範圍的局部疊合示意圖。第10A圖實施例與第7圖的差異在於，具有大出光面積的主字符A1位於透明膜32的光學框322的平直內緣與光學塊321之間，同時主字符A1也局部被底板23的橋肋231b擋住；子字符A2則位於底板23的邊孔232b內。第10A圖的主膠體54增設了第二個缺口54A2指向主字符A1，並且不搭配子膠體56。缺口54A與54A2的大小可以與字符距離成正比，也可以跟字符發光面積成正比；此外，缺口54A與54A2的兩個指向夾角與兩個字符A1/A2的指向夾角相近或一致(以發光單元26為中心)。由於該處沒有子膠體56耦合光線進出導光板30，也能讓更多光線橫向傳遞到上下三個邊孔232b，再出光照亮主字符A1。換言之，缺口54/54A可以單獨使用，搭配子膠體56並非絕對必要。再者，如有需要，微光學層31a或31b上可以設置微圖案MP，且膠合件34可以增設島膠56i與微圖案MP重疊，二者也可進一步與底板23邊孔232b/主字符A1重疊；不過，島膠56i並不與光學塊321或光學框322重疊。如此將能透過島膠56i的光線耦合效果，提高主字符A1的出光效果。第10B圖實施例與第10A圖的差異在於，除了子膠體56a指向子字符A2之外，膠合件34進一步增設第二個子膠體56b在缺口54A2指向主字符A1。此外，第10B圖中，膠合件34(含主膠體56、缺口54A/54A2、子膠體56a/56b、無膠環區54B)都位在主字符A1與子字符A2，這是主字符A1與子字符A2位在發光單元26相反側時，優化後的膠合件34設計。Referring to Figure 10A/10B, Figure 10A is a partially superimposed schematic diagram of the luminous keyboard 10 in another embodiment of the present invention in the area of a single key 12; Figure 10B is a schematic diagram of the luminous keyboard 10 in another embodiment of the present invention in a single key area. A partial overlay diagram of the range of button 12. The difference between the embodiment in Figure 10A and Figure 7 is that the main character A1 with a large light-emitting area is located between the straight inner edge of the optical frame 322 of the transparent film 32 and the optical block 321. At the same time, the main character A1 is also partially covered by the base plate 23. The bridge ribs 231b are blocked; the sub-character A2 is located in the side hole 232b of the bottom plate 23. The main colloid 54 in Figure 10A has a second gap 54A2 pointing to the main character A1 and does not match the sub-colloid 56. The size of the notches 54A and 54A2 can be proportional to the distance between the characters and the light-emitting area of the characters; in addition, the two pointing angles of the notches 54A and 54A2 are similar or consistent with the pointing angles of the two characters A1/A2 (based on the light-emitting unit 26 as the center). Since there is no sub-colloid 56 coupling light in and out of the light guide plate 30, more light can be transmitted laterally to the upper and lower side holes 232b, and then light can be emitted to illuminate the main character A1. In other words, the notch 54/54A can be used alone, and it is not absolutely necessary to match the sub-colloid 56. Furthermore, if necessary, micro-pattern MP can be provided on the micro-optical layer 31a or 31b, and the glue 34 can be added with island glue 56i to overlap the micro-pattern MP, and both of them can also be further connected with the side hole 232b/main character A1 of the base plate 23 overlap; however, the island glue 56i does not overlap with the optical block 321 or the optical frame 322. In this way, the light coupling effect of the island glue 56i can be used to improve the light emission effect of the main character A1. The difference between the embodiment of Figure 10B and Figure 10A is that in addition to the sub-colloid 56a pointing to the sub-character A2, the glue 34 further adds a second sub-colloid 56b in the gap 54A2 to point to the main character A1. In addition, in Figure 10B, the glued parts 34 (including the main colloid 56, the notch 54A/54A2, the sub-colloid 56a/56b, and the glue-free ring area 54B) are located between the main character A1 and the sub-character A2. This is the main character A1 and the sub-character A2. The optimized design of the glue piece 34 when the sub-character A2 is on the opposite side of the light-emitting unit 26.
參考第6/7/8/9/10A/10B圖，為達到優異的均光效果，膠合件34與透光膜32上光學塊321的相對尺寸設計有其探討必要。首先，膠合件34(含主膠體54與子膠體56)的外徑最好大於遮擋塊231B，這是因為主膠體54增加的局部出光量若全部被遮擋塊231B吸收或遮擋，無疑是出光量的無謂損耗。不過，當膠合件34的外徑大於底板23內孔231c而重疊底板23環肋231c，光路會取決於底板23材質；如果底板23是可反射的金屬材質、或塗佈反光油墨，光線仍然可以被回收。其次，膠合件34的外徑若大於反光塊321W，將會造成該處較亮，除非字符位於其正上方，或者膠合件34超出反光塊321W的部分重疊可反射的底板23環肋231c，通常膠合件34的外徑以不大於反光塊321W較佳。不過，視需要讓膠合件34部分超出(露出)反光塊321W，也是增加可控的出光量的有效手段。基於前述配置，遮擋塊321B重疊無膠環區54B和無微點區54C，遮擋塊321B的外徑也大於無膠環區54B和無微點區54C。此外無膠環區54B與光學框322內緣的距離，也會大於光學塊321外緣與光學框322內緣的距離。Referring to Figures 6/7/8/9/10A/10B, in order to achieve excellent light uniformity effect, it is necessary to discuss the relative size design of the optical block 321 on the glued part 34 and the light-transmitting film 32. First of all, the outer diameter of the glued piece 34 (including the main colloid 54 and the sub-colloid 56) is preferably larger than the blocking block 231B. This is because if the local light emission increased by the main colloid 54 is completely absorbed or blocked by the blocking block 231B, the light emission amount will undoubtedly be reduced. deadweight loss. However, when the outer diameter of the glued piece 34 is larger than the inner hole 231c of the bottom plate 23 and overlaps the ring rib 231c of the bottom plate 23, the light path will depend on the material of the bottom plate 23; if the bottom plate 23 is made of reflective metal or coated with reflective ink, the light can still be Be recycled. Secondly, if the outer diameter of the glued member 34 is larger than the reflective block 321W, it will cause the area to be brighter, unless the characters are located directly above it, or the part of the glued member 34 that exceeds the reflective block 321W overlaps the reflective bottom plate 23 ring rib 231c, usually The outer diameter of the glued member 34 is preferably no larger than the reflective block 321W. However, if necessary, allowing the glued member 34 to partially exceed (expose) the reflective block 321W is also an effective means to increase the controllable light output. Based on the aforementioned configuration, the blocking block 321B overlaps the glue ring-free area 54B and the micro-dot-free area 54C, and the outer diameter of the blocking block 321B is also larger than the glue-ring-free area 54B and the micro-dot-free area 54C. In addition, the distance between the glue-free ring area 54B and the inner edge of the optical frame 322 will be greater than the distance between the outer edge of the optical block 321 and the inner edge of the optical frame 322 .
