O QUE SIGNIFICA SHADOW MASK EM INGLÊS
Máscara de sombra
A máscara de sombra é uma das tecnologias usadas para fabricar televisores de tubos de raios catódicos e displays de computadores que produzem imagens coloridas. Outra abordagem é a grelha de abertura, mais conhecida pelo seu nome comercial, Trinitron. Todas as televisões em cores iniciais e a maioria dos monitores de computador CRT utilizaram tecnologia de máscara de som. Ambas as tecnologias são em grande parte obsoletas, tendo sido cada vez mais substituídas desde a década de 1990 pela exibição de cristais líquidos. Uma máscara de sombra é uma placa de metal perfurada com pequenos orifícios que separam os fósforos coloridos na camada atrás do vidro dianteiro da tela. Três canhões de elétrons na parte de trás da tela varrem a máscara, com os feixes apenas atingindo a tela se eles atravessam os buracos. À medida que as armas estão fisicamente separadas na parte de trás do tubo, suas vigas se aproximam da máscara de três ângulos ligeiramente diferentes, então, depois de passar pelos orifícios, atingiram locais ligeiramente diferentes na tela. A tela é modelada com pontos de fósforo coloridos posicionados para que cada um só possa ser atingido por um dos raios provenientes das três pistolas de elétron.
definição de shadow mask no dicionário inglês
A definição de máscara de sombra no dicionário é uma folha de metal perfurada montada perto da tela em ponto de fósforo em alguns tubos de televisão a cores. Os furos são posicionados de modo que cada um dos três feixes de elétrons atinge o ponto de fósforo correto produzindo a mistura de cor necessária na imagem.

The shadow mask is prepared from a separate double-sided polished silicon
wafer. Standoffs are incorporated into the side of the shadow mask that will
contact the SOI wafer, to avoid any contact with patterned features in the silicon
