<p>This invention covers input-output devices and in particular desktop computer, laptop computer, «pocket» computer, wired and mobile telephone keyboards and other units equipped with an input-output device. The technical result of this invention is the expansion of the functional capabilities and adding the convenience of use to input-output devices when working with applications that allow multiple character sets in multitasking operating systems, as well as adding the convenience to using input-output devices. The technical result is achieved by providing a keyboard with internal partitions and placing sources of light in the formed spaces; making the keys' top surfaces partially transparent for the luminescence and turning on the corresponding group of luminescence depending on the character set being currently active.</p> |
