Abstract

"DISPOSITIVO DE EXIBIçãO". A presente invenção relaciona-se a um dispositivo de exibição, compreendendo uma tela (1) com vários pixéis. Cada pixel possui uma estrutura emissora de elétron (8, 9, 11), tal como uma combinação porta-catodo. Os elétrons emitidos por cada estrutura emissora de elétron (8, 9, 11) são acelerados na direção de uma camada de anodo (12) na tela (1). A camada de anodo (12) é subdividida em várias porções separadas (12a, ..., 121), e cada uma de tais porções possui um medidor de corrente correspondente (15a, ..., 151) para medir a parte da porção da corrente de anodo total do dispositivo de exibição. Isto acarreta uma capacidade melhorada das propriedades de medição das estruturas emissoras de elétrons individuais, o que serve para ajustar cada sinal da estrutura emissora de elétron no sentido de obter um dispositivo de exibição mais uniforme.
