Abstract

<B>MéTODO E APARELHO PARA A ILUMINAçãO DE UM DISPOSITIVO DE ENTRADA DE DADOS<D> Um dispositivo de entrada de dados provê uma iluminação por trás para um botão (150), por meio de um painel eletroluminescente (EL) (142), localizado no dispositivo. O botão é parte de uma pluralidade de botões conformados em um teclado integral e maleável, onde cada botão corresponde a uma função específica. O painel EL localizado abaixo do teclado é seletivamente iluminado, e corresponde diretamente a cada botão. Uma chave de domo (136), que pode ser engatada pelo botão, está localizada abaixo do painel EL, e provê uma retroalimentação tátil. Uma camada de circuito, localizada diretamente abaixo da chave de domo, compreende um circuito de chave ativado dali. Uma ling³eta de painel EL (144) é formada no painel EL por um vazio (160), e a ling³eta corresponde à localização do botão. O vazio permite que a ling³eta se mova livremente em uma direção vertical, conforme o botão ativar a chave de domo.<B> METHOD AND APPARATUS FOR LIGHTING A DATA ENTRY DEVICE <D> A data entry device provides backlight for a button (150), by means of an electroluminescent panel (EL) (142), located on the device. The button is part of a plurality of buttons formed on a full and malleable keyboard, where each button corresponds to a specific function. The EL panel located below the keyboard is selectively illuminated, and corresponds directly to each button. A dome switch (136), which can be engaged by the button, is located below the EL panel, and provides a tactile feedback. A circuit layer, located directly below the dome switch, comprises a switch circuit activated there. An EL panel tab (144) is formed on the EL panel by a void (160), and the tab corresponds to the location of the button. The vacuum allows the tab to move freely in a vertical direction, as the button activates the dome switch.
