Teste LCD

Um teste LCD exibe cores solidas em tela cheia - vermelho, verde, azul, branco e preto - para que vazamento de luz, pixels presos e iluminacao desigual fiquem visiveis contra um fundo uniforme em poucos segundos. Abra a ferramenta, toque em cada amostra de cor para preencher a tela inteira e procure qualquer ponto, linha ou area que nao corresponda a cor ao redor.

Tambem chamado de teste de tela ou teste de display, este teste LCD e o mesmo diagnostico rapido: mostrar uma cor solida por vez para que pixels mortos ou presos e vazamento de luz se destaquem contra um fundo uniforme.

Why trust these tools

  • Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
  • No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
  • Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
  • Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
  • Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
