[Technical field to which the invention belongs]

 The present invention relates to a kind of keyboard light source display structure, in particular, one light emitting element is centrally arranged on a keyboard layer, and displays a key position on a keyboard, or displays a position of an important key or a function key, The present invention relates to a keyboard light source display structure that allows a user to quickly find a key that needs to be pressed.

[Prior art]

 Keyboard technology has already evolved from a wired keyboard with a limited range of use to a remote-controlled wireless keyboard in consideration of the convenience of user application, and with the improvement in computer technology, the basic arithmetic logic has been improved. In addition, coupling with home appliances has become a major trend. In particular, a combination of a basic light source switch is given. However, most of the existing keyboards do not have a light source display design, and when the user wants to operate the light source switch in the house with the wireless keyboard, the position of the wireless keyboard is not known or the position of the key to be pressed is not known. If you do not find one light switch in the dark, you may not be able to perform the remote control function of the wireless keyboard. This was a fall at the end of the day, and on the contrary, it left a useless function of the wireless keyboard, and became a major problem in promoting sales to users.

[0003] Therefore, in order to remedy this drawback, the industry manufactures a key set with a transparent material, mounts a light emitting diode on a circuit, and activates the light emitting diode to emit a light beam when a key switch is activated. And a key set so that the user can confirm the location of the key position. However, when the light emitting diode was directly mounted on the circuit board, the following disadvantages occurred. 1. The light emitting diode and the wireless keyboard receive the same power supply and switch control. When the light emitting diode is activated, the wireless keyboard is also activated, and when the user uses the wireless keyboard, in the early morning or when there are enough light beams in the room, the light emitting diode is activated. Power on, which significantly reduces the power supply time inherent in the wireless keyboard, causing the user to run out of power immediately when using the wireless keyboard, and the inconvenience of having to change batteries. occured. 2. Mounting a light emitting diode directly on a circuit board can easily destroy the key command circuit, which is inherently complicated in manufacturing, increases the manufacturing cost, lowers the yield, and increases the load on the circuit board, which causes some users to use it. If used for a long period of time, the light emitting diode may be damaged or an error condition may occur in the key command, and the key command may not be replaced. Therefore, the consumption cost of the user is increased, and it is very inconvenient. 3. Manufacturers were unable to update the number and location of light emitting diodes due to market demands and user habits, and were limited in mounting models.

[0004]

[Problems to be solved by the invention]

 The main object of the present invention is to solve the above-mentioned drawbacks and eliminate the drawbacks, that is, the present invention concentrates one light emitting element on the keyboard layer and transmits the light to the light source through the keyboard. By doing so, the key position of the keyboard is displayed, or the position of the important key or the function key is displayed, so that the user can quickly find the key that needs to be pressed.

Another object of the present invention is to constitute the light emitting device with a plurality of pieces of cold light plates or cold cathode plates of different colors or the same color.

[0006] Still another object of the present invention is to open a single light-transmitting hole in the keytop or make the keytop completely transparent or translucent, thereby providing a keytop for the light source of the light emitting device. The key is used for important or function keys so that the user can find the key that needs to be pressed in a short time.
