Abstract

The invention relates to a light-emitting keyboard, which comprises a plurality of keys, a thin film switch circuit, a support plate and a backlight module. The thin film switch circuit is arranged below the plurality of keys, and comprises an upper circuit board, a lower circuit board and a separating layer. The support plate is arranged below the thin film switch circuit and is connected to theplurality of keys. The backlight module is arranged below the support plate to generate light beams. The peripheral area of at least one of the upper circuit board, the lower circuit board and the separating layer is bent to cover the support plate and the backlight module to prevent the beams from overflowing from the peripheral area of the backlight module.

Description

technical field [0001] The invention relates to a keyboard, in particular to a luminous keyboard with a luminous function. Background technique [0002] Common computer peripheral input devices include a mouse, a keyboard, and a trackball. The keyboard can directly input text and symbols to the computer, so it is highly valued by users and input device manufacturers. [0003] see figure 1 , which is a schematic diagram of an appearance structure of an existing keyboard. There are a plurality of keys 10 on the surface of the existing keyboard 1, and these keys 10 are classified into general keys 101, number keys 102, and function keys 103, etc. These keys are pressed by the user's fingers to generate corresponding signals. The computer enables the computer to execute the pressed key functions, for example, the general key 101 is used to input symbols such as English letters, the number key 102 is used to input numbers, and the function key 103 is used to provide various fun...
