Como distinguir a qualidade de Telas de LED<\/a><\/span>?<\/span><\/strong><\/h6>

Vamos aprender os seguintes pontos sobre a qualidade de um colorido Display LED<\/a>.<\/span><\/p>

Planicidade<\/span><\/strong><\/h6>

O nivelamento da superf\u00edcie de uma tela de LED deve ser de \u00b1 1 mm para garantir que a imagem da tela n\u00e3o seja distorcida, e a protuber\u00e2ncia ou recuo local pode causar um \u00e2ngulo cego no \u00e2ngulo de vis\u00e3o da tela. O processo de produ\u00e7\u00e3o determinou principalmente o nivelamento.<\/span><\/p>

Brilho e \u00e2ngulo de vis\u00e3o<\/span><\/strong><\/h6>

O brilho da tela colorida interna deve estar acima de 800cd \/ m2, e o brilho da tela colorida externa deve estar acima de 5500cd \/ m2 para garantir a opera\u00e7\u00e3o normal do monitor. Caso contr\u00e1rio, o brilho ser\u00e1 muito baixo e ser\u00e1 dif\u00edcil ver a imagem exibida. A qualidade do dado LED determinou principalmente o tamanho do brilho. O tamanho do \u00e2ngulo de vis\u00e3o determina diretamente a audi\u00eancia da tela, ent\u00e3o um \u00e2ngulo de vis\u00e3o maior \u00e9 melhor. O m\u00e9todo de embalagem da matriz determinava principalmente o \u00e2ngulo de vis\u00e3o.<\/span><\/p>

Efeito de equil\u00edbrio de branco<\/span><\/strong><\/h6>

O efeito do balan\u00e7o de branco \u00e9 um dos indicadores mais importantes de um display LED. Na ci\u00eancia das cores, quando a propor\u00e7\u00e3o das tr\u00eas cores prim\u00e1rias de vermelho, verde e azul \u00e9 1: 4,6: 0,16, o branco puro \u00e9 exibido. Se a propor\u00e7\u00e3o real se desviar ligeiramente, haver\u00e1 um desvio do equil\u00edbrio de branco. Geralmente, deve-se observar se a cor branca \u00e9 azulada ou amarelada. Fen\u00f4meno verde. O sistema de controle do display LED determinou principalmente a qualidade do balan\u00e7o de branco. O dado tamb\u00e9m influencia a redutibilidade da cor.<\/span><\/p>

Redutibilidade de cor<\/span><\/strong><\/h6>

A redu\u00e7\u00e3o da cor refere-se \u00e0 redu\u00e7\u00e3o da cor da tela do display LED. E, a cor da tela do display de LED deve ser altamente consistente com a cor da fonte de reprodu\u00e7\u00e3o, de modo a garantir o realismo da imagem.<\/span><\/p>

Existe um fen\u00f4meno de mosaico ou ponto morto?<\/span><\/strong><\/h6>

Mosaico se refere aos quatro quadrados claros ou escuros que aparecem na tela do visor LED. N\u00e3o \u00e9 apenas a qualidade dos conectores usados no display LED, mas a qualidade dos conectores.<\/span><\/p>

O ponto morto refere-se ao \u00fanico ponto de luz ou escurid\u00e3o que aparece no display LED. A qualidade do dado determinou principalmente o n\u00famero de pontos mortos.<\/span><\/p>

N\u00e3o h\u00e1 bloco de cor<\/span><\/strong><\/h6>

As amostras de cores referem-se \u00e0 diferen\u00e7a de cores \u00f3bvia entre os m\u00f3dulos adjacentes. O fen\u00f4meno da corre\u00e7\u00e3o de cores \u00e9 causado principalmente pelo sistema de controle deficiente, baixo n\u00edvel de cinza e baixa frequ\u00eancia de varredura.<\/span><\/p>

Controle de taxa de ponto cego<\/span><\/strong><\/h6>

A taxa de pontos cegos \u00e9 geralmente de pontos brilhantes, pontos mortos e pontos escuros. A taxa de ponto cego das telas externas deve ser inferior a 3\/10000, e a taxa de ponto cego das telas internas deve ser controlada em 2\/10000.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\t\t\t\t\t<\/div>\t\t<\/div>\t\t\t\t\t<\/div>\t\t<\/section>\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
