Description

Description: Title The abiliy to use electronic keyboards/pads in light deficient environments.
Current Situation: Current portable electronic devices, which have some from of keyboard/key pad. used for inputting information and a screen for displaying information E. g.
Laptops, Notebooks.
Palmtops Hand-held computers that close like laptops And handheld electronic computers/devices are unable to be used in areas where natural or artificial light is at a premium or nonexistent as the light from the screen is inadequate to allow the user to see the keys and hence the characters on the kesboard or keypad.
Invention This invention allos s the use of equipment that uses am power supply be it batten operated or ran from the electrical supply which uses a keyboardlpad be it numeric and/or alphabetic and/or punctuational and/or anx other tSpe To be used in areas where natural light or artificial light is at a premium or non existent The manner in which this is done is outlined in the next sub-section: Details To make keys on a keyboard/pad from an illuminate coating so that light from the screen xxill allow the user to see the keys. Such devices could be but is not limited : -Laptops -Notebooks -Palm tops -Hand held devises that close like the above devices.
-Hand held computers/devices that have keys.
The illuminate keys can be made in the following way : The key itself can be made from the illuminate coating with the actual alphabetic. numeric or punctuation character (s) made from a NON-illuminate/shaded material.
In cases where there are multiple characters on a single key then each character will be individually made from the NON-ilIuminate material/sIiaded material. m reference to Diagram 1 Detailed cxamp ! e : In the below examples (diagram 1) the key which is the blute area is made from the illuminate material and the character (s) on the key is made from a material that is NOT illuminating. Also referred to in this paper as shaded.

Claims (1)

  1. Claims This invention of using keys made from or coated with an illuminate material and the characters on the kens to be made from a non-illuniinate material on a keypad/keyboard will allow the use of Laptops.
    Notebooks.
    Palm-tops Hand-held computers that close like laptops and Hand-held electronic derices/computers in light deficient areas more effectively as described in the description section.
