Problems solved by technology

[0005] However, for the luminous keyboards on the market, when the user leaves the seat or is not typing on the luminous keyboard at all, the luminous keyboard still judges that the light intensity is insufficient and emits light as usual
If no user is using the glowing keyboard, it is just a waste of electricity, increasing costs and burdens

Abstract

The invention discloses an illuminant keyboard and an illuminating method for the keyboard. The illuminant keyboard comprises an illuminating module, a first sensing module, a second sensing module and a control module. The first sensing module is used for sensing surround light. When the luminance of the surround light is lower than the reference luminance, the first sensing module generates a first signal. The second sensing module is used for sensing the contact state of the illuminant keyboard and generating a second signal according to the contact state. The control module is respectively connected with the illuminating module, a first sensor and a second sensor and is used for driving the illuminating module to illuminate according to the first signal and the second signal.

Description

technical field [0001] The invention relates to a luminous keyboard and a keyboard luminous method, in particular to a luminous keyboard with power saving function and a keyboard luminous method. Background technique [0002] With the development of science and technology, due to the rapid development of the information industry in recent years, many users may use portable information devices in different environments. For example, a notebook computer (notebook) or a personal digital assistant (personal digital assistant, PDA). In a low-light environment, users may not be able to clearly see the numbers and characters marked on the keyboard keys, making operations difficult, and in severe cases, may even cause visual impairment due to barely recognizing the key marks. Therefore, the launch of the luminous keyboard can improve the inconvenience of using the keyboard in places with insufficient light. [0003] The advantage of the luminous keyboard is that in places with wea...
