Abstract
"MOSTRADORES VISUAIS". Descreve-se sistemas de tela de mostrador de cristal líquido de ângulo de visualização variável. Eles são úteis, por exemplo, nas máquinas de caixa de terminal automáticas onde, durante partes de uma transação com um usuário, é desejável que a informação na tela possa ser lida por outros. De acordo com a invenção, interpostos em uma disposição de mostrador convencional do refletor (2), uma luz de fundo (1), um difusor (3), um elemento aumentador de brilho opcional (4,5) e uma tela do tipo de transmissão (6) são previstos um colimador (10) e um difusor variável (11). Se o difusor variável (11) é ajustado para ser transparente, a luz passando através da tela do tipo de transmissão (6) é ainda colimada e, desse modo, exibida na tela sendo somente visível de modo efetivo em um ângulo de visualização estreito. Se o difusor (11) for ajustado para difundir a luz colimada, então, o mostrador é visível por uma faixa muito grande de ângulos.
