多色发光按键及多色发光键盘Multi-color illuminated keys and multi-color illuminated keyboard

技术领域technical field

本实用新型关于一种按键及键盘，尤指一种具有平面光源且进一步能产生多色背光的发光按键及发光键盘。The utility model relates to a button and a keyboard, in particular to a luminous button and a luminous keyboard which have a plane light source and can further produce multi-color backlight.

背景技术Background technique

目前许多电子装置仍以多个按键或键盘为输入介面，例如电脑、手机等，当环境光线充足时，使用者正确按压按键均不成问题，然而当环境光线不足时，使用者则可能按错按键，甚至可能连所需按键的大略位置也无法确定，造成使用上的不便。因此，目前已有发光键盘问市，期以解决环境光线不足造成错误按压的问题。At present, many electronic devices still use multiple buttons or keyboards as the input interface, such as computers, mobile phones, etc. When the ambient light is sufficient, the user can press the button correctly. However, when the ambient light is insufficient, the user may press the wrong button , and even the approximate position of the desired key may not be determined, causing inconvenience in use. Therefore, there are currently luminous keyboards on the market, hoping to solve the problem of incorrect pressing caused by insufficient ambient light.

目前有一种发光键盘单纯提供背光以补偿环境光线不足，惟其背光除了穿过键帽的可透光部分以达到指示效果，亦从各键帽间缝隙溢出，此溢出的光线反而造成键帽指示的干扰，若背光相对环境光线过强，此溢出的光线则显得刺眼。另有一种发光键盘针对每一个键帽设置一点光源，以降低光线自键帽间溢出的程度。此单一点光源虽设计为仅照射对应的键帽，但因点光源尺寸与对应的键帽尺寸相距仍大，故若键帽有多个透光部，则点光源照射在此多个透光部上的光线便有不均匀的现象。事实上，除非透光部光扩散极佳，否则自键帽外部即可观察出透光部仍呈现有相对亮的亮点区域，此即对应点光源。此外，因为键帽与底板以一升降机构连接，且光线多自按键底板下发射，所以光线在到达键帽之前，极可能被升降机构阻挡、反射等，使得照射至键帽的光线的不均匀问题更形严重，亦使得自键帽间溢出光线的现象难以消除。另外，当发光键盘采用双色发光而于每一个键帽设置一对点光源，以分别发射不同色光时，若该对点光源非紧密相邻设置，则其混光的均匀度亦不佳，且照射在键帽上的光线整体均匀不佳的问题将更形严重。At present, there is a luminous keyboard that simply provides backlight to compensate for insufficient ambient light. However, the backlight not only passes through the light-transmitting part of the keycap to achieve the indication effect, but also overflows from the gap between the keycaps. Interference, if the backlight is too strong relative to the ambient light, the overflow light will appear dazzling. There is also a light-emitting keyboard with a little light source for each keycap to reduce the degree of light spilling from between the keycaps. Although this single point light source is designed to only illuminate the corresponding keycap, the distance between the size of the point light source and the size of the corresponding keycap is still large. The light on the part is uneven. In fact, unless the light diffusion of the light-transmitting portion is excellent, the light-transmitting portion still has a relatively bright bright spot area observed from the outside of the keycap, which corresponds to a point light source. In addition, because the keycap is connected to the bottom plate by a lifting mechanism, and the light is mostly emitted from the bottom of the keypad, so the light is likely to be blocked or reflected by the lifting mechanism before reaching the keycap, so that the light irradiated to the keycap is not uniform. The problem is more serious, and it also makes it difficult to eliminate the phenomenon of light spilling from between the keycaps. In addition, when the luminous keyboard adopts two-color light emission and a pair of point light sources are arranged on each keycap to emit light of different colors, if the pair of point light sources are not closely adjacent to each other, the uniformity of light mixing is not good, and The overall poor uniformity of the light irradiated on the keycap will be more serious.

因此，目前的发光键盘仍有照射不均、光线溢漏等问题，实有需要改变发光键盘的光源架构，以有效且均匀地投射光线于键帽的透光部，解决前述问题。Therefore, the current luminous keyboard still has problems such as uneven illumination and light leakage. It is necessary to change the light source structure of the luminous keyboard to effectively and uniformly project light on the light-transmitting portion of the keycap to solve the aforementioned problems.

具体实施方式Detailed ways

为使对本实用新型的目的、构造、特征、及其功能有进一步的了解，兹配合实施例详细说明如下。In order to have a further understanding of the purpose, structure, features, and functions of the present utility model, the detailed description is as follows in conjunction with the embodiments.

请参阅图1，其为根据本实用新型的一较佳实施例的多色发光按键1的剖面示意图。多色发光按键1包含底板12、键帽14、升降支架16及发光构件18。键帽14设置于底板12之上并以升降支架16与底板12连接，升降支架16使得键帽14能藉由一钟状弹性体(未标示于图中)的弹性相对底板12上下移动。发光构件18设置于底板12之下。底板12具有二镂空122。键帽14包含二透光部142，分别对应前述二镂空122。发光构件18包含基板182及复数个发光单元184。该复数个发光单元184分为两群，分别以平面排列方式形成于基板182上并形成发光区块186，对应前述镂空122其中之一。每一个发光区块186中的复数个发光单元184均能被选择性地驱动发光，通过对应的镂空122以进入对应的透光部142(如图中虚线箭头所示)。于本实施例中，发光构件18为场致发光薄膜(electroluminescent film)，但本实用新型不以此为限，其他能提供平面排列的复数个发光单元且能个别控制该复数个发光单元的光源装置亦得作为本实用新型的发光构件18。Please refer to FIG. 1 , which is a schematic cross-sectional view of a multi-color light-emittingkey 1 according to a preferred embodiment of the present invention. The multi-color light-emittingkey 1 includes abottom plate 12 , akeycap 14 , alifting bracket 16 and a light-emittingmember 18 . Thekeycap 14 is arranged on thebottom plate 12 and is connected with thebottom plate 12 by alifting bracket 16. Thelifting bracket 16 enables thekeycap 14 to move up and down relative to thebottom plate 12 by the elasticity of a bell-shaped elastic body (not shown in the figure). Thelight emitting member 18 is disposed under thebottom plate 12 . Thebottom plate 12 has twohollows 122 . Thekeycap 14 includes twotransparent portions 142 corresponding to the aforementioned twohollows 122 . Thelight emitting component 18 includes a substrate 182 and a plurality oflight emitting units 184 . The plurality oflight emitting units 184 are divided into two groups, which are respectively formed on the substrate 182 in a planar arrangement to form alight emitting block 186 corresponding to one of theaforementioned hollows 122 . The plurality of light-emitting units 184 in each light-emitting block 186 can be selectively driven to emit light through thecorresponding hollow 122 to enter the corresponding light-transmitting portion 142 (shown by the dotted arrow in the figure). In this embodiment, the light-emittingmember 18 is an electroluminescent film (electroluminescent film), but the utility model is not limited thereto, other light sources that can provide a plurality of light-emitting units arranged in a plane and can individually control the plurality of light-emitting units The device can also be used as thelight emitting member 18 of the present invention.

此外，于本实施例中，为避免各发光区块186内的发光单元184所发射的光线行进经非对应的镂空122溢出或防止来自他处非预期的光线经镂空122溢出，故于底板12朝向该复数个发光单元184的表面124上涂布吸光物质20，用以吸收光线，使得通过镂空122的光线原则上仅来自对应的发光区块186，其中吸光物质20的涂布范围固可及于底板12的整个表面124，但亦可仅及于镂空122周围处，抑或依实际产品设计规范而定，本实用新型不以此为限。In addition, in this embodiment, in order to prevent the light emitted by the light-emittingunits 184 in each light-emittingblock 186 from overflowing through thenon-corresponding hollows 122 or to prevent unexpected light from overflowing through thehollows 122, thebase plate 12 The light-absorbingsubstance 20 is coated on thesurface 124 facing the plurality of light-emittingunits 184 to absorb light, so that the light passing through the hollow 122 only comes from the corresponding light-emittingblock 186 in principle, and the coating range of the light-absorbingsubstance 20 can be reached. On theentire surface 124 of thebottom plate 12, but it can also only reach around the hollow 122, or it depends on the actual product design specifications, and the present invention is not limited thereto.

请并参阅图2，其为图1中发光构件18的俯视示意图。因于底板12有镂空之处，光线始能穿过，例如镂空122，故发光构件18的发光单元184原则上仅需于对应镂空之处设置即可，于本实施例中，发光区块186的轮廓分别与镂空122的轮廓实质上相同，但本实用新型不以此为限。另外于图2中，发光构件18显示出共有四个发光区块，故原则上底板12亦对应有四个镂空，但本实用新型仍不以此为限，例如若底板12的镂空上方尚有按键1其他构件遮阻，则于此构件正下方设置发光单元184的意义不大，此时该镂空即可能对应两个以上的发光区块。于图2中，每一个发光区块186划分成复数个小区间(cell)，以表示发光单元184，其中本实施例的发光构件18的发光单元184主要以蚀刻制程实现，故有些发光单元184得以非矩形轮廓呈现，可使得发光区块186的轮廓能与对应的镂空122的轮廓更为相符。又于本实施例中，发光单元184以矩形阵列排列成发光区块186，然于实际应用上，发光单元184亦得以交错排列的方式形成发光区块186，每一个发光单元184的轮廓可为矩形、菱形、圆形等；惟本实用新型均不以此为限。Please also refer to FIG. 2 , which is a schematic top view of thelight emitting member 18 in FIG. 1 . Because there is a hollow on thebottom plate 12, light can pass through, such as the hollow 122, so thelight emitting unit 184 of thelight emitting member 18 only needs to be installed in the corresponding hollow in principle. In this embodiment, thelight emitting block 186 The contours of are substantially the same as the contours of the hollow 122, but the present invention is not limited thereto. In addition, in Fig. 2, the light-emittingmember 18 shows a total of four light-emitting blocks, so in principle thebase plate 12 also has four corresponding hollows, but the utility model is not limited to this, for example, if there are still holes above the hollows of thebase plate 12 If other components of the key 1 are obstructed, it is meaningless to arrange the light-emittingunit 184 directly below this component. At this time, the hollow may correspond to more than two light-emitting blocks. In FIG. 2, each light-emittingblock 186 is divided into a plurality of small areas (cells) to represent light-emittingunits 184, wherein the light-emittingunits 184 of the light-emittingmember 18 of this embodiment are mainly realized by an etching process, so some light-emittingunits 184 Presented with a non-rectangular outline, the outline of the light-emittingblock 186 can be more consistent with the outline of the corresponding hollow 122 . Also in this embodiment, thelight emitting units 184 are arranged in a rectangular array to form thelight emitting blocks 186, but in practical applications, thelight emitting units 184 can also be arranged in a staggered manner to form thelight emitting blocks 186, and the outline of eachlight emitting unit 184 can be Rectangle, rhombus, circle etc.; But the utility model is all not limited to this.

此外，于本实施例中，该复数个发光单元184包含复数个能发射第一色光的第一发光单元1842(以标示有字母「R」的发光单元184表示)、复数个能发射第二色光的第二发光单元1844(以标示有字母「G」的发光单元184表示)及复数个能发射第三色光的第三发光单元1846(以标示有字母「B」的发光单元184表示)，其中第一色光为红色光，第二色光为绿色光，第三色光为蓝色光，该复数个第一发光单元1842、该复数个第二发光单元1844及该复数个第三发光单元1846交错设置，期以获得各色光的发光单元184能实质上均匀分布于基板182上，但本实用新型不以此为限；于实际产品中，各色光的发光单元184的分布可设光学指示设计的不同而定，例如于发光区块186的边缘部分仅设置蓝色光的发光单元184。因此，除了发光区块186发射的光线能远较习知技术中发光键盘的单一或少数的点光源来得均匀之外，亦可藉由控制发光区块186中每一个发光单元184的发光状态(例如开关、发光强度等)以使发光区块186整体产生不同的背光，穿过对应的镂空122再进入对应的透光部142。由于每一个发光区块186可独立控制发光，故每一个发光区块186所对应的透光部142自得以不同的颜色表现；此外，由于每一个发光区块186中每一个发光单元184亦得独立控制发光，故每一个发光区块186可产生多种光线投射效果，例如各种颜色的背光、不同颜色间的渐层、渲染效果等，每一个发光区块186对应的透光部142亦因此可呈现多种光学指示效果。In addition, in this embodiment, the plurality of light-emittingunits 184 include a plurality of first light-emitting units 1842 capable of emitting light of the first color (represented by the light-emittingunit 184 marked with the letter "R"), and a plurality of light-emitting units capable of emitting the second color light. A second light-emitting unit 1844 of colored light (represented by the light-emittingunit 184 marked with the letter "G") and a plurality of third light-emittingunits 1846 capable of emitting a third color light (represented by the light-emittingunit 184 marked with the letter "B"), Wherein the first color light is red light, the second color light is green light, and the third color light is blue light, the plurality of first light emitting units 1842, the plurality of second light emitting units 1844 and the plurality of thirdlight emitting units 1846 alternate It is set so that thelight emitting units 184 of each color light can be substantially evenly distributed on the substrate 182, but the utility model is not limited thereto; in actual products, the distribution of thelight emitting units 184 of each color light can be designed as an optical indicator Depending on the difference, for example, only the bluelight emitting unit 184 is disposed on the edge of thelight emitting block 186 . Therefore, except that the light emitted by the light-emittingblock 186 can be far more uniform than the single or a small number of point light sources in the light-emitting keyboard in the prior art, it is also possible to control the light-emitting state of each light-emittingunit 184 in the light-emitting block 186 ( Such as switches, luminous intensity, etc.) so that the light-emittingblock 186 as a whole generates different backlights, and passes through the corresponding hollow 122 and then enters the corresponding light-transmittingportion 142 . Since each light-emittingblock 186 can independently control light emission, the light-transmittingportion 142 corresponding to each light-emittingblock 186 can be expressed in different colors; in addition, because each light-emittingunit 184 in each light-emittingblock 186 can also Independent control of light emission, so each light emittingblock 186 can produce a variety of light projection effects, such as backlights of various colors, gradients between different colors, rendering effects, etc., and thelight transmission part 142 corresponding to eachlight emitting block 186 Therefore, various optical indication effects can be presented.

补充说明的是，由于每一个发光单元184可单独控制发光，因此发光构件18亦即提供动态变化的光线投射，更易导引使用者操作多色发光按键1，进一步提升其光学指示的功能。此外，于前述实施例中，每一个发光区块186均包含三种色光的发光单元184，但本实用新型不以此为限，例如仅包含二种或更少种类的色光或包含更多种类的色光的发光单元184亦可。另外，由于不同的发光材料或发光机制，并基于色彩原理，每一种色光的发光单元184的总发光面积不必然相同，于本实施例中，红色光的发光单元184的总发光面积大于缘色光或蓝色光的发光单元184的总发光面积，但本实用新型仍不以此为限。It is supplemented that since eachlight emitting unit 184 can individually control the light emission, thelight emitting member 18 also provides dynamically changing light projection, which is easier to guide the user to operate the multi-colorlight emitting button 1 and further enhances its optical indication function. In addition, in the foregoing embodiments, each light-emittingblock 186 includes three kinds of light-emittingunits 184 of color light, but the utility model is not limited thereto, for example, it only includes two or less kinds of color lights or includes more kinds Thelight emitting unit 184 of colored light is also available. In addition, due to different light-emitting materials or light-emitting mechanisms, and based on color principles, the total light-emitting area of the light-emittingunit 184 of each color light is not necessarily the same. In this embodiment, the total light-emitting area of the light-emittingunit 184 for red light is larger than that of the edge The total light emitting area of thelight emitting unit 184 of colored light or blue light, but the utility model is not limited thereto.

再补充说明的是，于前述实施例中，虽然一个透光部142对应一个镂空122及一个发光区块186，但本实用新型不以此为限。于实际应用上，为使发光构件18能提供更大面积、更均匀的光线投射，故原则上在能满足底板12的强度需求或其他结构性需求下，底板12尽可能地镂空；而键帽14的透光部142则利用自发光构件18射出且穿过镂空的光线投射以提供使用者光学指示的功能，一个发光区块186亦不必然仅能对单一透光部142提供背光。因此，发光区块186与透光部142的对应关系宜以实际产品结构而定，本实用新型不以前述实施例所呈现之结构为限。It should be added that, in the foregoing embodiments, although one light-transmittingportion 142 corresponds to one hollow 122 and one light-emittingblock 186 , the present invention is not limited thereto. In practical applications, in order to enable the light-emittingmember 18 to provide a larger area and more uniform light projection, in principle, thebottom plate 12 should be hollowed out as much as possible if the strength requirements or other structural requirements of thebottom plate 12 can be met; and the keycap The light-transmittingportion 142 of 14 utilizes light emitted from the light-emittingmember 18 and projected through the hollow to provide an optical indication function for the user, and one light-emittingblock 186 does not necessarily only provide backlight for a single light-transmittingportion 142 . Therefore, the corresponding relationship between the light-emittingblock 186 and the light-transmittingportion 142 should be determined according to the actual product structure, and the present invention is not limited to the structures presented in the foregoing embodiments.

请参阅图3，其为根据本实用新型的一较佳实施例的多色发光键盘3的剖面示意图。于本实施例中，多色发光键盘3包含复数个多色发光按键1，其中多色光发按键1中部分构件已整合，故多色发光键盘3包含底板12、复数个键帽14及发光构件18，底板12具有复数个镂空122，每一个键帽14设置于底板12之上并包含二透光部142，每一透光部142对应该复数个镂空122其中之一，发光构件18设置于底板12之下并包含基板182及对应每一个镂空122包含复数个发光单元184，该复数个发光单元184以平面排列方式形成于基板182上并能被选择性地驱动发光，通过对应的镂空122以进入对应的透光部142。于前述实施例中有关多色光发按键1各部件及其变形的说明于多色发光键盘3中可适用者，亦有其适用，不再赘述。Please refer to FIG. 3 , which is a schematic cross-sectional view of a multi-color luminous keyboard 3 according to a preferred embodiment of the present invention. In this embodiment, the multi-color luminous keyboard 3 includes a plurality of multi-colorluminous keys 1, wherein some components of the multi-colorluminous keys 1 have been integrated, so the multi-color luminous keyboard 3 includes abottom plate 12, a plurality ofkeycaps 14 and light-emittingcomponents 18. Thebottom plate 12 has a plurality ofhollows 122, eachkeycap 14 is arranged on thebottom plate 12 and includes two light-transmittingparts 142, each light-transmittingpart 142 corresponds to one of the plurality ofhollows 122, and the light-emittingmember 18 is set on Thebottom plate 12 includes a substrate 182 and a plurality of light-emittingunits 184 corresponding to each hollow 122. The plurality of light-emittingunits 184 are formed on the substrate 182 in a planar arrangement and can be selectively driven to emit light. Through the corresponding hollow 122 to enter the correspondingtransparent portion 142 . The descriptions about the components of the multi-color light-emittingkeypad 1 and their deformations in the foregoing embodiments are also applicable to the multi-color light-emitting keyboard 3 , and will not be repeated here.

因此，多色发光键盘3的每一个多色发光按键1均可独立地发挥光学指示功能，其详细说明及变化型请径参阅前述实施例中多色光发按键1中相关的说明，不再赘述。此外，由于各个键帽14，甚至单一键帽14上的各个透光部142均可独立呈现光学指示效果，故多色发光键盘3的复数个键帽14的透光部142整体可作为光学指示屏幕，用以提供较大的光学指示图案，显有别于习知技术中仅能对单一键帽14提供光学指示的效果，故多色发光键盘3具有新颖的光学指示效果。Therefore, each multi-color light-emittingkey 1 of the multi-color light-emitting keyboard 3 can independently perform an optical indication function. Please refer to the relevant description of the multi-color light-emitting key 1 in the foregoing embodiment for details and variations, and will not repeat them here. . In addition, since eachkeycap 14, or even each light-transmittingportion 142 on asingle keycap 14 can independently present an optical indication effect, the entire light-transmittingportion 142 of the plurality ofkeycaps 14 of the multi-color luminous keyboard 3 can be used as an optical indication. The screen is used to provide a larger optical indication pattern, which is obviously different from the prior art which can only provide an optical indication effect for asingle keycap 14, so the multi-color luminous keyboard 3 has a novel optical indication effect.

综上所述，相较于先前技术，本实用新型的多色发光按键及多色发光键盘利用复数个发光单元，针对底板的镂空，以平面排列方式设置，以提供均匀的光线投影，解决习知技术中光线投射不均匀的问题，亦能抑制键帽间光线溢漏的问题。进一步地，藉由各个发光单元的独立发光之特性，本实用新型可实现各种色光及色彩变化的光学指示效果，亦得以键盘整体为显示屏幕，提供较大的光学指示图案，提供使用者新颖的光学指示效果。To sum up, compared with the prior art, the multi-color luminous keys and the multi-color luminous keyboard of the present utility model use a plurality of light-emitting units, aiming at the hollowing out of the bottom plate, and arrange them in a plane arrangement to provide uniform light projection and solve the problem of conventional lighting. It solves the problem of uneven light projection in the known technology, and also suppresses the problem of light leakage between keycaps. Further, by virtue of the independent light-emitting characteristics of each light-emitting unit, the utility model can realize various optical indication effects of color light and color change, and also use the keyboard as a whole as a display screen to provide a larger optical indication pattern, providing users with a novel optical indication effect.
