Abstract

a presente invenção refere-se ao campo das comunicações, e as modalidades da presente invenção apresentam um método e um aparelho de supressão de interferência para um painel de toque, usado para melhorar a precisão da comutação da frequência operacional de um painel de toque. o método de supressão de interferência para um painel de toque compreende: a aquisição de uma frequência operacional de um adaptador de carregamento e uma frequência de instabilidade do adaptador de carregamento; e o emprego, de acordo com a frequência operacional e a frequência de instabilidade, de um algoritmo predeterminado para calcular um intervalo de baixo ruído para a operação de um painel de toque, de maneira tal que o intervalo de baixo ruído do painel de toque seja adquirido, e a frequência operacional do painel de toque é comutada para que fique dentro do intervalo de baixo ruído se a interferência para o painel de toque for maior do que uma faixa predeterminada, em que o intervalo de baixo ruído é um intervalo de frequência operacional do painel de toque em que a interferência para o painel de toque fica dentro de uma faixa predeterminada.
