发明名称 Unevenly illuminated keyboard
摘要 An unevenly illuminated keyboard has a mask element between a luminous element and keycaps which are illuminated by the luminous element. The mask element has a permeable zone corresponding to each keycap and an impermeable zone on the neighboring area of the keycap but not beneath thereof such that the light emitted from the luminous element projects and illuminates the individual keycap to form the unevenly illuminated keyboard that illuminates only the keycaps.
