Claims (7)

  1. 一種用於指紋接觸之面板，其包括一板件，具有一第一表面及一第二表面，該第一表面係相對於該第二表面，該第一表面係為一光擴散面，該光擴散面係供一手指接觸於其上，該第二表面係朝向一光學取像系統，該光擴散面係經由紫外線塗層處理(Ultra-Violet Coating)或模具放電處理而形成霧狀微粒的表面，且該光擴散面的霧化度(Haze)係為85%至95%；其中，該光學取像系統包括至少一發光元件，該發光元件係用於朝向該板件發射至少一光線，當該發光元件發射該光線至該光擴散面時可增加散射，當該光線接觸該手指時，該光擴散面利於弱化該光線的散射。
  2. 如請求項1所述之用於指紋接觸之面板，其中該光學取像系統更包括一感應元件，該感應元件係朝向該板件用以擷取該光線經由該手指所傳遞該手指的一指紋圖案。
  3. 如請求項2所述之用於指紋接觸之面板，更包括一微結構，設置於該第二表面，該微結構用以使該光線通過該微結構後使該光線均勻射向該板件。
  4. 如請求項2所述之用於指紋接觸之面板，其中該光學取像系統更包括一光擴散板，設置於該發光元件及該板件之間，該光擴散板用以使該光線通過該擴散板後使該光線均勻射向該板件。
  5. 一種用於指紋接觸之面板，其包含：一板件，具有一第一表面及一第二表面，該第一表面係相 對於該第二表面，該第二表面係朝向一光學取像系統；以及一膜片，具有一光擴散面，該膜片以該光擴散面貼合於該板件之該第一表面，令該光擴散面位於該板件與該膜片之間，且該膜片遠離該光擴散面之另一面係供一手指接觸於其上，該膜片的該光擴散面係經由紫外線塗層處理(UV Coating)或模具放電處理而形成霧狀微粒，且該膜片的該光擴散面的霧化度(Haze)係為85%至95%；其中，該光學取像系統包括至少一發光元件，該發光元件係用於朝向該板件發射至少一光線，當該發光元件發射該光線至該膜片的該光擴散面時可增加散射，當該光線接觸該手指時，該光擴散面利於弱化該光線的散射。
  6. 如請求項5所述之用於指紋接觸之面板，其中該光學取像系統更包括一感應元件，該感應元件係朝向該板件用以擷取該光線經由該手指所傳遞該手指的一指紋圖案。
  7. 如請求項6所述之用於指紋接觸之面板，其中該光學取像系統更包括一擴散板，設置於該發光元件及該板件之間，該擴散板用以使該光線通過該擴散板後均勻射向該板件。
