Apostila B\u00e1sica de LCD Em continua\u00e7\u00e3o aos Treinamentos de manuten\u00e7\u00e3o de Monitores vamos estudar o conceito b\u00e1sico sua teoria B\u00e1sica.
Compara\u00e7\u00e3o entre Monitores de CRT Convencional e LCD
Os dois tipos comuns de monitores que est\u00e3o sendo usados hoje s\u00e3o CRT (Tubo de Raio de Catodo) monitores L\u00edquido) . Os monitores de tipo de CRT s\u00e3o os monitores tradicionais que n\u00f3s temos usados por anos. Os monit baseados em uma mais nova tecnologia e est\u00e3o tornando muito popular, principalmente porque eles t\u00eam grande econ outras vantagens acima de monitores de CRT.
O CRT e monitores de LCD s\u00e3o baseados em tecnologias completamente diferentes, e deste modo tenham caracter\u bastante diferentes.
Tamanho f\u00edsico
Umas das grandes vantagens de monitores de LGD \u00e9 que eles s\u00e3o compactos e de peso leve. Um monitor de L tela muito fina ao inv\u00e9s do tubo vultoso de um monitor de CRT.
Isto significa que n\u00e3o s\u00f3 eles come\u00e7am a estar nos seus Desktop devido ao se tamanho como espa\u00e7o com em muitos lugares onde um monitor de CRT n\u00e3o pode ser montado. Mostrado abaixo est\u00e3o temos um monitor de 12.1" M uma espessura apenas de um ter\u00e7o do t\u00edpico monitor de 14" com uso de CRT.
Tamanho de v\u00eddeo.
Gra\u00e7as a alta tecnologia do LCD, monitores de LCD de painel plano est\u00e3o agora dispon\u00edveis no mercado e s\ de tela com monitores de CRT tradicional. Mostrado aqui, um 12.1" V\u00cdDEO de LCD (esquerda) tem s\u00f3 um ligeiramente m um t\u00edpico MONITOR de 14\u00a8 de CRT. Mais novos, monitores de LCD MAIORES tamb\u00e9m est\u00e3o aparecendo qu muito maior que s\u00e3o compar\u00e1veis para os maiores monitores de CRT. Uma diferen\u00e7a b\u00e1sica pode ser notada precisamente de tamanhos de sua tela. viewable) medida em diagonal.
Por exemplo, o viewable \u00e1rea em um MONITOR de 17" de LCD tipicamente medir\u00e1 17" diagonalmente, mas o monitor de CRT tipicamente s\u00f3 medir\u00e1 16" diagonalmente.
Cores.
Na maioria dos monitores de CRT s\u00e3o qualificados de exibir cores ilimitadas. Diferentemente de monitores de LCD qu centenas ou milhares de cores, embora muitos dos mais novos LCD s\u00e3o qualificado de cores ilimitadas.
Resolu\u00e7\u00e3o.
Um assunto importante com respeito aos monitores de LCD \u00e9 resolu\u00e7\u00e3o. Os monitores de CRT s\u00e3o exibir resolu\u00e7\u00f5es de v\u00eddeo m\u00faltiplo, cada com a mesma qualidade, porem os monitores de LCD normalmente resolu\u00e7\u00e3o, ou a resolu\u00e7\u00e3o em que os sinais de v\u00eddeos tem alta resposta de freq\u00fc\u00eancias. Brilho.
Tipicamente, brilho n\u00e3o \u00e9 uma preocupa\u00e7\u00e3o com monitores de CRT. Porem os monitores de LCD s\u00e3 brilho. O brilho para o monitor de LCD \u00e9 tamb\u00e9m chamado de 'l\u00eandeas ', e comumente variem de 70 at\u00e9 250 l\ l\u00eandeas, mais brilhante \u00e9 o v\u00eddeo.
Visualizando \u00c2ngulo.
Outro assunto com rela\u00e7\u00e3o ao monitor de LCD \u00e9 o visualiza\u00e7\u00e3o do \u00e2ngulo. Uma tela de largo, praticamente de todo os lados, mas um monitor de LCD tipicamente tem um menor visualizando \u00e2ngulo, precisando ser diretamente da frente. Do lado, a imagem em uma tela de LCD pode aparecer ou desaparecer, ou inverter cores. Mais novos monitor que est\u00e3o sendo desenvolvidos como os de matriz ativa t\u00eam um maior campo de vis\u00e3o angular.
Vantagens do LCD sobre o CRT. Baixo consumo de energia e de Radia\u00e7\u00e3o
Al\u00e9m de serem compactos e ocuparem pequenos espa\u00e7os, os monitores de LCD oferecem v\u00e1rios o de LCD possuem um menor consumo de energia se comparado monitores de CRT. Este faz o LCD grande para computadores po port\u00e1teis. Secundariamente, MONITORES de CRT s\u00e3o conhecidos como emissores de radia\u00e7\u00e3o sendo pre monitores de LCD que tem radia\u00e7\u00e3o.
Desvantagens do LCD sobre o CRT. Pre\u00e7os.
Os monitores de CRT s\u00e3o geralmente mais dispon\u00edveis que monitores de LCD e com pre\u00e7os abaixo. No p sido muito caros mas seus custos vieram caindo bastante nos \u00faltimos anos. Por\u00e9m as empresas est\u00e3o se preocupan que esta aumentando a procura por monitores LCD.
