Light-emitting keyboard

Abstract

The invention provides a light-emitting keyboard which comprises a thin-film circuit board, key structures and light-emitting elements, wherein the key structures are used for conducting a thin-film switch of the thin-film circuit board and each comprises a keycap, a connecting element and a soft shielding cover. The connecting element is located between the thin-film circuit board and the keycapand enables the keycap to move up and down relative to the thin-film circuit board. The soft shielding cover is connected to the keycap and surrounds the connecting element, and is used for projectingthe light beams provided by at least some of the light-emitting elements to the soft shielding cover and generating reflection on the soft shielding cover, so as to further output the light from thelight-transmitting part of the keycap. In this way, the use efficiency of the light is improved.

Description

technical field [0001] The invention relates to the field of keyboards, in particular to a keyboard with a light-emitting function. Background technique [0002] In recent years, due to the rapid development of the information industry, many users may use portable information devices in different environments, such as notebook computers, mobile phones or personal digital assistants. In a low-light environment, users may not be able to clearly see the numbers and characters marked on the keyboard keys, thus causing difficulties in operation, and in severe cases, may even cause vision loss due to barely recognizing the key marks. Therefore, the launch of the luminous keyboard can improve the inconvenience of the user using the keyboard in places with insufficient light. What's more, through different lighting configurations, the information device using the lighting keyboard can be made to look more beautiful, thereby increasing its sales. [0003] see Figure 1 ~ Figure 4 ,...

Problems solved by technology

[0007] However, the disadvantage of the existing luminous keyboard 1 is that, since there is a gap between the key caps 151 of any two adjacent key structures 15 and between the key caps 151 of any key structure 15 and the key frame 17, the upward scattering Among the light beams L111, only a part of the light beams L111a will be output from the multiple light-transmitting parts 1511 (that is, the characters or numbers) of the keycap 151, but another part of the light beams L111b will be output from any two adjacent keycaps. The gap between 151 or the gap between any keycap 151 and key frame 17 is lost outwards, which will cause the defects of uneven luminous effect or insufficient brightness of the plurality of light-transmitting parts 1511 (that is, text or numbers)

[0008] Therefore, the existing luminous keyboard has room for improvement due to poor light use efficiency
