Description

发光键盘
技术领域
本实用新型是有关于一种发光键盘,且特别是有关于一种具有量子点发光组件的发光键盘。
背景技术
键盘装置作为电脑系统中指令输入/输出的设备,对使用者非常重要,在光线不足的情况下,为了让使用者仍能清晰辨识出键帽上的字符,键盘厂商开发出了适用于黑暗环境中的发光键盘。但现有的发光键盘一般采用LED光源加导光组件的设计,使得发光键盘整体厚度较厚,不利于键盘的轻薄化设计。再者,LED光源经由导光组件横向光传导之后再射出至键帽,会导致光损失,光利用率降低。另外,现有的发光键盘一般仅能发出单色光,视觉效果单调,不能满足使用者更多的需求。因此,开发一种极薄化,光利用率高,且可发出多色光的发光键盘成为值得研发的课题。
实用新型内容
本实用新型的主要目的在于,提供一种发光键盘,具有极薄化、光利用率高、可发多色光的特点。
为了实现上述目的,本实用新型提供一种发光键盘,包括底板、多个键帽、薄膜电路及量子点发光组件。多个键帽分别通过升降机构连接底板。薄膜电路设置于底板上,并位于底板与多个键帽之间。量子点发光组件设置于多个键帽下方。其中,量子点发光组件受电激发而发出光线,且光线穿过多个键帽的透光区。
本实用新型的一实施例中,该量子点发光组件设置在该底板与该薄膜电路之间。
本实用新型的一实施例中,该量子点发光组件设置于该底板下。
本实用新型的一实施例中,该量子点发光组件设置在该薄膜电路上。
本实用新型的一实施例中,该量子点发光组件设置于该多个键帽的底面。
本实用新型的一实施例中,该量子点发光组件包括多个量子点发光体及至少一封装层,其中该至少一封装层覆盖该多个量子点发光体。
本实用新型的一实施例中,该多个量子点发光体设置于该薄膜电路上。
本实用新型的一实施例中,该量子点发光组件还包括一载体,且该多个量子点发光体设置于该载体。
本实用新型的一实施例中,发光键盘还包括一电源供应单元,电性连接该量子点发光组件。
本实用新型的一实施例中,该量子点发光组件受电激发时能发出至少一种颜色的光。
基于上述,在本实用新型实施例的发光键盘中,量子点发光组件发出的光可直接射出至键帽,而不需要经由导光组件,可降低光横向传导而造成的光损失,提高光利用率。再者,量子点发光组件通过纳米级的量子点发光体封装而形成,其本身具有轻、薄的特点,且键盘结构中不需设置导光组件,可进一步降低键盘整体厚度,实现极薄化。另外,量子点发光组件中可包含不同特性(材质、形状、大小等)的量子点发光体,其受电激发可发出不同颜色的光,从而实现更丰富的视觉效果。
为让本实用新型的上述特征和优点能更明显易懂,下文特举实施例,并配合所附图式作详细说明如下。

具体实施方式
图1为本实用新型的一实施例的发光键盘1的剖面示意图。请先参考图1,本实施例的发光键盘1包括底板10、多个键帽20(图中仅示例性的画出一个键帽)、薄膜电路30及量子点发光组件40。多个键帽20分别通过升降机构50与底板10连接,以使多个键帽20可相对底板10上下运动。且每个键帽20分别具有透光区(图中未示出),以供光线穿透而发光。薄膜电路30设置于底板10上,并位于底板10与多个键帽20之间。量子点发光组件40设置于底板10与薄膜电路30之间,且量子点发光组件40可受电激发而发出光线,光线穿透多个键帽20的透光区,从而使多个键帽20发光。
请再参考图2,图2绘示本实用新型的另一实施例的发光键盘1的剖面示意图。在本实施例中,量子点发光组件40设置于底板10的下方,底板10上与多个键帽20对应的位置分别设有破孔(图中未示出),量子点发光组件40发出的光分别从破孔射出至多个键帽20的透光区。
请再参考图3,图3绘示本实用新型的又一实施例的发光键盘1的剖面示意图。在本实施例中,量子点发光组件40设置在薄膜电路30上,其发出的光直接射出至多个键帽20的透光区。
请再参考图4,图4绘示本实用新型的又一实施例的发光键盘1的剖面示意图。在本实施例中,发光键盘1包括多个量子点发光组件40,分别对应设置于多个键帽20的底面。多个量子点发光组件40发出的光分别直接射出至多个键帽20的透光区。
请再参考图5A,图5A绘示本实用新型的一实施例的量子点发光组件40的剖面示意图。在本实施例中,量子点发光组件40包括多个量子点发光体401及一封装层402,且多个量子点发光体401被封装层402覆盖。封装层402的作用主要是为了使量子点发光体401与水、氧隔离,从而防止其氧化。封装层402的材质可以是常用的透光封装胶,例如环氧树脂,改性环氧树脂,有机硅材料等。
请再参考图5B,图5B绘示本实用新型的另一实施例的量子点发光组件40的剖面示意图。在本实施例中,量子点发光组件40包括多个量子点发光体401及多个封装层402,且封装层402的数量与量子点发光组件40的数量相同,也就是说,每个量子点发光体401分别被一个封装层402覆盖。
请再参考图5C,图5C绘示本实用新型的又一实施例的量子点发光组件40的剖面示意图。在本实施例中,量子点发光组件40包括多个量子点发光体401及多个封装层402,且量子点发光体401的数量多于封装层402的数量。也就是说,其中一些封装层402分别覆盖一个量子点发光体401,而另外一些封装层402分别覆盖多个量子点发光体401。但本新型并不对此进行限制,每个封装层402覆盖的量子点发光体的数量可以根据实际需要进行设置。
请再一并参考图5A至图5C,在一实施例中,量子点发光组件40还包括一载体403,且多个量子点发光体401设置于载体403上。载体403的材质可为玻璃或者可挠性薄膜。在一实施例中,量子点发光组件40可直接以发光键盘1的薄膜电路30为载体,意即是,多个量子点发光体401可直接设置在薄膜电路30上,如此可进一步减薄发光键盘1的整体厚度。
在一实施例中,量子点发光组件40受电激发时可以发出一种颜色的光。在另一实施例中,量子点发光组件40受电激发时可以发出多种颜色的光。需要说明的是,量子点发光体401受电激发时发出的光线的颜色与其自身特性(材质、形状、大小等)有关。当量子点发光组件40包含多个不同特性(材质、形状、大小等)的量子点发光体401时,即可发出多种不同颜色的光。但量子点发光组件40的发光颜色可根据实际需要进行变化,本实用新型并不对此进行限制。
请再一并参考图6A至图6D,其分别绘示本实用新型的多个实施例的键帽20的发光效果示意图。在一实施例中,键帽20上具有多个字符201,键帽20对应于该些字符201分别具有透光区域202。该些透光区域202相互独立,也就是说,该些透光区域202互相不连接。在一实施例中,该些透光区域202透出的光线颜色各不相同。在其他实施例中,该些透光区域202透出的光线颜色也可以相同,本实用新型并不对此进行限制。
在一实施例中,键帽20上具有透光区域202,透光区域202上设置有多个字符201。透光区域202对应于多个字符201透出的光线颜色可以是一种,也可以是多种。透光区域202的形状可以是矩形,也可以是其他不规则的形状。但透光区域的形状和透出的光线颜色可根据实际需要进行变化,本实用新型并不对此进行限制。
另外,在本实用新型的一实施例中,发光键盘1还包括一电源供应单元(图中未示出),其电性连接量子点发光组件40,以使量子点发光组件40受电激发而发光。电源供应单元例如是电路板,量子点发光组件40可以直接设置于电路板上,也可以通过导线连接至该电路板。但电源供应单元的具体结构以及量子点发光组件40与电源供应单元的具体连接方式可根据实际需要进行设置,本实用新型并不对此进行限制。
综上所述,在本实用新型的发光键盘中,量子点发光组件发出的光可直接射出至键帽,而不需要经由导光组件,可降低光横向传导而造成的光损失,提高光利用率。再者,量子点发光组件通过纳米级的量子点发光体封装而形成,其本身具有轻、薄的特点,且键盘结构中不需设置导光组件,可进一步降低键盘整体厚度,实现极薄化。另外,量子点发光组件中可包含不同特性(材质、形状、大小等)的量子点发光体,其受电激发可发出不同颜色的光,从而实现更丰富的视觉效果。
虽然本实用新型已以实施例揭露如上,然其并非用以限定本实用新型,任何所属技术领域中具有通常知识者,在不脱离本实用新型的精神和范围内,当可作些许的更动与润饰,故本实用新型的保护范围当视后附的权利要求范围所界定者为准。
