Abstract

dispositivos eletrônicos com sensores de toque ópticos resistentes a umidade. a presente invenção refere-se a um dispositivo eletrônico que pode ter uma tela sensível ao toque que é insensível à presença de umidade. uma matriz de pixels na tela pode ser usada para exibir imagens. uma camada de cobertura de tela pode ser sobreposta à matriz de pixels. uma fonte de luz pode iluminar um objeto externo como um dedo de um usuário quando o objeto entra em contato com uma superfície da camada de cobertura de tela. isso cria uma luz difusa que pode ser detectada por uma matriz de sensores de luz. a fonte de luz pode fornecer luz a uma borda da camada de cobertura de tela a um ângulo que assegura que a reflexão interna total dentro da camada de cobertura de tela seja sustentada através da camada de cobertura de tela mesmo quando a camada de cobertura de tela está imersa em água ou, então, exposta a umidade.
