Problems solved by technology

[0003] However, the above-mentioned luminous keyboard needs to use an additional light guide plate combined with the keyboard assembly for light guide, which requires a high cost of light guide, and when the keyboard is used in a dark place, the leakage of visible light from the keyboard is serious, resulting in poor visibility of the keyboard.

Abstract

The invention relates to a light-emitting keyboard, which comprises a word key, a frame plate, a thin film layer, a switching circuit layer and a bottom plate, wherein the word key is connected with the frame plate, and can move up and down relative to the frame plate; the word key, the frame plate, the thin film layer, the switching circuit layer and the bottom plate are sequentially arranged from top to bottom; the light-emitting keyboard also comprises a light-emitting source arranged below the word key; the light-emitting source is a light source capable of emitting the invisible light; a light-emitting material is also arranged on the keyboard; and the light-emitting material is excited by the light-emitting source to emit the visible light so as to irradiate the keyboard. The light-emitting keyboard has the advantage of reducing the light leakage.

Description

technical field [0001] The invention relates to an input device of electronic equipment, in particular to a thin light-emitting keyboard used in electronic equipment such as computers. Background technique [0002] Most of the current computer keyboards do not self-illuminate. Therefore, it is difficult to operate when the light is dark. For this reason, some people have developed luminous keyboards. These luminous keyboards can pass the light emitted around the keys or The light penetrating through the center of the key allows the user to clearly distinguish between different keys, and also brings a novel appearance to the user. For example, Chinese patent CN200820125924.4 discloses a luminous keyboard, which includes word keys arranged in sequence, bridging component, light-transmitting bottom plate, light-guiding plate, light-emitting diode and reflective sheet, the bridging component connects the word key and the light-transmitting bottom plate, so that the word key can ...
