发光键盘及其应用于发光键盘的薄膜电路板
摘要：
本发明关于一种发光键盘及其应用于发光键盘的薄膜电路板，所述发光键盘包括：一薄膜电路板，于底面印制有一导光油墨；一光源，设于所述薄膜电路板的一侧，用以投射光线至所述薄膜电路板的导光油墨；一第一反射板，设于所述薄膜电路板的下方，用以将散射的光源反射进入所述薄膜电路板的导光油墨；一第二反射板，设于所述薄膜电路板的上方，以使未穿透过所述第二反射板的部份光线反射回所述导光油墨上；一支撑托架，设于所述第二反射板的上方；一剪刀支架，设于所述支撑托架的上方；一键帽，设于所述剪刀支架的上方；以及一弹性触动体，设有一触压部。本发明的发光键盘，不仅降低键盘的制造成本，同时降低键盘整体的厚度，且也提高发光的效率。
摘要（英）：

The invention relates to a light-emitting keyboard and a thin film circuit board applied in the light-emitting keyboard, the light-emitting keyboard comprises the thin film circuit board, a light source, a first reflection plate, a second reflection plate, a support bracket, a scissor support, a keycap and an elastic touch body, wherein a light guide ink is printed on the bottom surface of the thin film circuit board; the light source is arranged on one side of the thin film circuit board and used for projecting light to the light guide ink of the thin film circuit board; the first reflectionplate is arranged below the thin film circuit board and used for reflecting the scattered light source into the light guide ink of the thin film circuit board; the second reflection plate is arrangedabove the thin film circuit board and used for reflecting the partial light which does not penetrate the second reflection plate back to the light guide ink; the support bracket is arranged above thesecond reflection plate; the scissor support is arranged above the support bracket; the keycap is arranged above the scissor support; and the elastic touch body is provided with a touch pressure part. The light-emitting keyboard can not only reduce the manufacturing cost of the keyboard and simultaneously reduce the overall thickness of the keyboard, but also improve the luminous efficacy.
