Problems solved by technology

[0008] In the light-emitting button 21, the shading cover 213 is attached to the plastic film 25 in an adhesive manner, and such a combination method is likely to cause many problems: first, in the process of adhering the shading cover 213 on the plastic film 25, the shading cover 213 is attached to the plastic film 25. 213 is prone to positional displacement and cannot align the opening 2131 of the light shield 213 with the light-emitting element 23, so that only part of the light beam generated by the light-emitting element 23 can pass through the opening 2131, while the other part of the light beam is blocked. Cover 213 blocks, so it will cause the luminous effect of the luminous button 21 is not obvious and it is not easy to distinguish whether the luminous button 21 is luminous
Second, an assembly error is likely to occur between the light shield 213 and the plastic film 25, so that the light shield 213 of the keyboard 2 after manufacture is easy to fall off, and when the light shield 213 falls off, the light beam produced by the light emitting element 23 cannot Concentrated by the hood 213 and diverged to all directions, it also causes the problem that the luminous effect of the luminous button 21 is not obvious
That is to say, when the user touches the key cap 211, the user will have a bad operating feeling due to the interference of the light shield 213 on the key cap 211.

Abstract

The invention relates to a keyboard device with a light emitting key. The keyboard device comprises at least one light emitting key, at least one light emitting component, a thin film switching circuit, light-proof sealing compound and light-transmitting sealing compound. The light emitting key is provided with a light-transmitting area, and the light emitting component is electrically connected with the thin film switching circuit and arranged below the light-transmitting area. The light-transmitting sealing compound is used for wrapping the upper surface of the light emitting component, the light-proof sealing compound partially wraps the light-transmitting sealing compound, and light beams generated by the light emitting component can penetrate through the light-transmitting sealing compound to be projected to the light-transmitting area. The keyboard device solves the problem in the existing keyboard device with the light emitting key that a light shading cover falls off and guarantees good operation touch.

Description

technical field [0001] The present invention relates to a keyboard device, in particular to a keyboard device with luminous keys. Background technique [0002] Common computer peripheral input devices include mouse devices, keyboard devices, and trackball devices. Among them, the keyboard device can directly input text and symbols to the computer, so it is quite valued by users and input device manufacturers. [0003] Firstly, the structure and function of the existing keyboard device are described, please refer to figure 1 , which is a schematic diagram of the appearance structure of the existing keyboard device. The surface of the existing keyboard device 1 has a plurality of keys 10 and a plurality of indicator lights 11. These keys 10 are classified into general keys, number keys, and function keys. Corresponding signals are given to the computer to make the computer perform the functions of the pressed keys, such as general keys for inputting symbols such as English l...
