Illuminated keyboard and electronic device using same

The present invention relates to an illuminated keyboard and an electronic device using the same, and more particularly to an illuminated keyboard having a backlight module and an electronic device using the same.

In recent years, electronic devices have often used electronic devices to process various materials because electronic devices can process data quickly. Since the portable electronic device can be carried around, the user can input data instantly. The portable electronic device can be, for example, a notebook computer. When information is to be input into the notebook, the user can use a component such as a keyboard to input data. When the user is in an environment with a dim light, the user often cannot clearly observe the contents of the button. Therefore, some manufacturers have developed an illuminated keyboard with a backlight module to make it easy for the user to observe the contents of the button.

In a typical illuminated keyboard, there is usually a bracket to increase the mechanical strength of the illuminated keyboard. However, the support plate usually requires additional mold making. Therefore, in the overall process of the illuminated keyboard, the manufacturing process of manufacturing the support plate must be increased, thereby increasing the manufacturing man-hour and manufacturing cost of the illuminated keyboard.

In view of the above problems, the present invention proposes an illuminated keyboard and an electronic device using the same to avoid the increased manufacturing man-hour and manufacturing cost when manufacturing the support plate.

One embodiment of the present invention provides an illuminated keyboard comprising a backlight module and a button module. The backlight module includes a circuit board and at least one light emitting component. The light emitting element is disposed on the circuit board. The button mold is assembled on the circuit board. The light generated by the illuminating element faces the button module. The ratio of the thickness of the circuit board to the length of the circuit board is 0.8/358 to 1.5/280.
