US 2018/0122598 A1 · FILTERS FOR SELECTING ALPHABET OF CHARACTERS PRESENTED BY KEYBOARD

Abstract

A computing system may include a keyboard and at least one backlight. The keyboard may include at least one key. The at least one key may include a first filter shaped according to a first character in a first alphabet. The first filter may transmit light within a first spectral range. The at least one key may also include a second filter shaped according to a second character in a second alphabet. The second filter may transmit light within a second spectral range. The at least one backlight may be configured to shine light of a first wavelength within the first spectral range in response to an instruction to display the first alphabet, and shine light of a second wavelength within the second spectral range in response to an instruction to display the second alphabet.
