Abstract

"ILUMINAçãO SELETIVA DE REGIõES DE UMA TELA ELETRÈNICA". é descrita a iluminação seletiva de uma tela (5) para um dispositivo eletrónico (1) que possa reduzir o consumo de potência da bateria. A invenção fornece um método para detectar um evento que provoque a atualização da tela (5) e para ativação dos elementos da iluminação (27) para iluminar a tela e determinar se a informação a ser exibida ocupará uma região (B-L) da tela. Se positivo, a região da tela é iluminada seletivamente por um ou mais dos elementos da iluminação. O período de tempo de iluminação predeterminado pode depender de uma combinação selecionada de um tamanho da região, de uma posição de região e/ou de uma prioridade associada com o evento.
