O que \u00e9 um Display COB LED?<\/strong><\/h2>\n\n

Os displays COB (Chip-on-Board) LED s\u00e3o um tipo de display LED onde os\u00a0chips LED s\u00e3o diretamente montados no PCB (Borda de Circuito Impresso)<\/strong>\u00a0e ent\u00e3o encapsulados. Este m\u00e9todo completamente selado os chips LED, tornando-os mais dur\u00e1veis e confi\u00e1veis em compara\u00e7\u00e3o com os displays SMD tradicionais.<\/p>\n\n

Caracter\u00edsticas Principais dos Displays COB:<\/strong><\/h3>\n\n
    \n
  1. Alta Densidade<\/strong>: A tecnologia COB permite\u00a0menores espa\u00e7amentos de p\u00edxeis<\/strong>\u00a0(abaixo de 1.0mm), resultando em imagens mais n\u00edtidas e detalhadas.<\/li>\n\n
  2. Durabilidade Aumentada<\/strong>: Os chips LED s\u00e3o completamente encapsulados, tornando os displays COB\u00a0mais resistentes a danos<\/strong>\u00a0durante o transporte, instala\u00e7\u00e3o e uso.<\/li>\n\n
  3. Fino e Leve<\/strong>: Os displays COB s\u00e3o\u00a0ultrafinos e leves<\/strong>, tornando sua instala\u00e7\u00e3o e transporte mais f\u00e1ceis.<\/li>\n\n
