Normas da Philips quanto ao defeito de pixel

Anomalias de Pontos Brilhantes As anomalias de pontos brilhantes aparecem como pixels ou sub- pixels que estão sempre acesos ou "ligados". Isto é, um ponto brilhante é um sub-pixel que sobressai no ecrã quando o monitor apresenta um padrão escuro. Há três tipos diferentes de anomalias de pontos brilhantes:

Um subpixel claro vermelho, verde ou azul

Dois subpixels adjacentes claros:

-Vermelho + azul = roxo

-Vermelho + verde = amarelo

-Verde + azul = ciânico (azul claro)

Três subpixels adjacentes claros (um pixel branco)

Um ponto brilhante vermelho ou azul deve ser 50% mais brilhante do que os pontos vizinhos enquanto um ponto brilhante verde é 30% mais brilhante do que os pontos vizinhos.

Anomalias de Pontos Pretos As anomalias de pontos pretos aparecem como pixels ou sub-pixels que estão sempre escuros ou "desligados". Isto é, um ponto preto é um sub-pixel que sobressai no ecrã

quando o monitor apresenta um padrão claro. Estes são os tipos de anomalias de pontos pretos:

Um subpixel escuro

Dois ou três subpixels adjacentes escuros

Proximidade dos defeitos de pixel

Pelo fato de os defeitos de pixel e subpixel do mesmo tipo e que estejam próximos um do outro serem mais perceptíveis, a Philips também especifica tolerâncias para a proximidade de defeitos de pixel.
