Description

多色发光按键及多色发光键盘 Multicolor light emitting multicolor light-emitting keys and keyboards

技术领域 FIELD

[0001] 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。 [0001] The present invention relates to a keyboard key and, particularly, to a planar light source having a luminous key and further produce multicolor backlight and a light emitting keypad.

背景技术 Background technique

[0002] 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。 [0002] Many electronic devices still plurality of keys or keyboard input interface, such as computers, mobile phones, when ambient light is sufficient, the user presses the right button are not a problem, however, when ambient light is insufficient, the user may pressed the wrong button, possibly even the approximate location of the desired key can not be determined, causing inconvenience to use. 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。 Therefore, there are illuminated keyboard asked the city, in order to solve the problems caused by lack of ambient light error compressions.

[0003] 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。 [0003] Currently there is a light emitting keypad backlighting simply insufficient to compensate for ambient light, but their addition to the backlight passes through the transmissive portion of the key top to achieve results indicate also overflow from the gap between each of the key top, the light but cause overflow bond cap interference indication, if the backlight relative ambient light is too strong, it appears that this overflow glare light. 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。 Another kind of point source light emitting keypad is provided for each key top, to reduce the degree of light overflowing from between the keycaps. 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勻的现象。 Although this single point light source designed to illuminate only the corresponding keycap, but the size of the keycap corresponding to the point light source and the size of the distance is still large, so if there are a plurality of light transmitting key top portion, the plurality of point light source light transmitting this phenomenon on the light there uneven portion. 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。 In fact, unless an excellent light diffusing light transmitting portion, otherwise, it is observed that continued to show a conventional light-transmissive region of relatively bright highlights key top from the outside portion, namely corresponding point source. 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勻问题更形严重,亦使得自键帽间溢出光线的现象难以消除。 Further, since the keycap and the base plate is connected to a lift mechanism, and the plurality of light emission from the key under the floor, so the light before reaching the key top, the lift mechanism is likely to be blocked and reflection, so that light is irradiated to the uneven keycaps the problem even more serious, but also makes the phenomenon of light spill from between keycaps difficult to eliminate. 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,则其混光的均勻度亦不佳,且照射在键帽上的光线整体均勻不佳的问题将更形严重。 Further, when using two-color LED illuminated keyboard and a pair of point light sources to each keycap to respectively emit different color lights, if the light-source closely adjacent to the point set, which light mixing uniformity also poor, and irradiating light on the whole problem of poor uniformity keycap will become even more serious.

[0004] 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,以有效且均勻地投射光线于键帽的透光部,解决前述问题。 [0004] Thus, the current is still illuminated keyboard irradiation unevenness, light spills and other issues, there is a need to change the architecture of the luminescent keyboard light source to effectively and uniformly projects light on the light transmitting key top portion, solve the aforementioned problems.

[0020] 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IM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。 [0020] Further, in the present embodiment, the light traveling through the light emitting unit 184 to prevent the respective light-emitting blocks 186 corresponding to the non-transmitted hollow 122 prevents light from the overflow or elsewhere unexpected overflow through the hollow 122, so the base plate 12 toward the plurality of light emitting cells on the surface of the IM 184 is coated absorbing material 20 for absorbing light, so that the hollow 122 by the principle of light from only the light emitting block corresponding to 186, wherein the application range of the light-absorbing substance 20 may be fixed and the entire surface of the bottom plate 12 of the 124, but may only at the periphery and in the hollow 122, or according to design specifications depending on the actual product, the present invention is not limited thereto.

[0021] 请并参阅图2,其为图1中发光构件18的俯视示意图。 [0021] Please refer to FIG. 2 and plan view in FIG. 1 which is a schematic view of the light emitting member 18. 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。 Due to the base plate 12 has a hollow, the light passes through before they can, for example hollow 122, it can be provided only in the hollow 184 corresponding to the principle of the light emitting unit emitting member 18, in the present embodiment, the light emitting block 186 the contour of the hollow profile 122 are substantially the same, but the present invention is not limited thereto. 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。 Further in FIG. 2, the light emitting member 18 exhibit a total of four light-emitting blocks, so that in principle corresponds to the bottom plate 12 also has four hollow, but the present invention is still not limited to, for example, above the hollow plate 12 when there is other barrier cover member 1 button, the member thereto is provided directly below the light emitting unit 184 of little significance, in which case the hollow i.e. may correspond to two or more light-emitting blocks. 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。 In Figure 2, each light emitting block 186 is divided into a plurality of subintervals (Cell), to indicate that the light emitting unit 184, wherein the light emitting unit 184 of the present embodiment, the light emitting member 18 of the main etch process to achieve, so that some of the light emitting unit 184 non-rectangular profile is presented, the profile may be such that the light emitting blocks 186 corresponding to the contour can be more consistent with the hollow 122. 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。 Also in the present embodiment, the light emitting unit 184 are arranged in a rectangular array of light-emitting block 186, then in practice, the light emitting unit 184 is also formed in a staggered manner emitting block 186, the contour of each light emitting unit 184 may be rectangle, diamond, circular, etc.; but the present invention is not limited thereto.

[0022] 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能实质上均勻分布于基板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。 [0022] Further, in the present embodiment, the plurality of the light emitting unit 184 comprises a plurality of first color emits a first light emitting unit 1842 (to mark the letter "R" represents a light emitting unit 184), a plurality of energy the second light emitting unit 1844 emits a second color light (in a light emitting unit marked with the letter "G" represents 184) and a plurality of third color light can emit a third light emitting unit 1846 (the light emitting unit to indicate the letter "B" 184 shown), wherein the first color is red light, second color light is green light, and third color is blue light, the plurality of first light emitting unit 1842, the plurality of second light emitting unit 1844 and the plurality of third light emission interleaving unit 1846 is provided, to the light emitting unit 184 of the color light can be obtained substantially evenly distributed on the substrate 182, but the present invention is not limited thereto; the actual product, the distribution of each color light emitting unit 184 may be provided optically indicating different designs depending, for example, to the edge portion 186 of the light emitting block is provided only blue light emitting unit 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勻之外,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。 Thus, in addition to the light emitted from the light emitting block 186 can be a single light emitting far more than the conventional art keyboard or a few point light source is more uniform, also by controlling the light emitting state of each light-emitting block 186 of the light emitting unit 184 ( such as switches, emission intensity) of the light emitting block to produce different overall backlight 186, 122 through the corresponding hollow re-entering the corresponding light transmitting portion 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 Since each light emitting block 186 may be independently controlled to emit light, so that each light emitting block 186 corresponding to the transmissive portion 142 is different from the color performance; In addition, since each light emitting block 186 in each light emitting unit 184 Yide independently controlled to emit light, so that each light emitting block 186 may generate a plurality of light projection effects, such as a backlight of various colors, gradient between different colors, rendering the like, each light emitting block corresponding to the light transmitting portion 186 is also 142 therefore it was

5现多种光学指示效果。 5 now indicates various optical effects.
