Abstract

Abstract A keypad apparatus (100) with integral display indicator bars (102-104) provides input to a device while displaying the status of the device on the display indicator bars (102-104). The apparatus is comprised of a matrix of data input keys (101). The indicator bars (102-104) are coupled to the matrix of keys (101), the apparatus (100) being manufactured as a single unit. Both the data input keys (101) and the indicator bars (102-104) are comprised of substantially the same material; a flexible and translucent silicone material. This material enables the keypad apparatus, that is backlit by the device, to diffuse the light, thereby lighting the data keys. Each indicator bar (102-104) has an individual backlight (108) from the device, allowing a particular indicator bar to be lit individually.
