Claims (11)

  1. 一種顯示裝置，其包含：一光源，其用於放射複數個顏色之光；一元件，其設置於各個像素中，用於選擇性地切換以導致從該光源放射之光之一通過或從該光源放射之光之一不通過；及一控制單元，其用於驅動各個像素之該光源及該元件以表現個別灰階以在複數個子訊框期間之各者達成光通過的一存在或光通過之一不存在，其中該複數個子訊框期間形成用於顯示一影像訊框之一個訊框期間，其特徵在於：該複數個子訊框期間分類為：一第一群組，其包括長度相同之子訊框期間；及一第二群組，其包括具有較該第一群組中的該等子訊框期間之該長度還短且互不相同之長度之子訊框期間；其中對於該第一群組，隨著該灰階之一增加，對於一像素，開始於一個訊框期間之中途且連續朝向該一個訊框期間的起始及結束之光通過期間之子訊框期間的數目增加；且其中該複數個子訊框期間之各者包括複數個顏色光通過期間，該複數個顏色光通過期間之各者通過由該光源放射之該複數個顏色之一者。
  2. 如請求項1之顯示裝置，其中以一交替方式設置屬於該 第一群組之該等子訊框期間及屬於該第二群組之該等子訊框期間。
  3. 如請求項1之顯示裝置，其中在該第一群組之一子訊框期間之前設置該第二群組之一第一至少二個子訊框期間且在該第一群組之該子訊框期間之後設置該第二群組之一第二至少二個子訊框期間，該第一群組之該子訊框期間代表該第一群組之該子訊框期間之所有者中最低灰階。
  4. 如請求項1之顯示裝置，其中在該第一群組之每二個相鄰子訊框期間之間設置一空白期間或該第二群組之該等子訊框期間之一者。
  5. 如請求項1之顯示裝置，其中：針對該複數個子訊框期間之至少一子訊框期間，設置接近從該一個訊框期間的該中途至該一個訊框期間的該起始，相對於該複數個顏色光通過期間之任何其他者更接近該一個訊框期間的該起始設置對應於藍色系顏色的該顏色光通過期間；且針對該複數個子訊框期間之至少一子訊框期間，設置接近從該一個訊框期間的該中途至該一個訊框期間的該結束，相對於該複數個顏色光通過期間之任何其他者在接近該一個訊框期間的該結束設置對應於藍色系顏色的該顏色光通過期間。
  6. 如請求項5之顯示裝置，其中，設置該第二群組之該等子訊框期間之一者在對應於藍色系顏色的該顏色光通過 期間以及對應於該複數個顏色之其他者之該複數個顏色光通過期間之一者之間。
  7. 如請求項1之顯示裝置，其進一步包含：一第一像素，其中針對一增加灰階，在光通過期間，安置該第一群組之子訊框期間之增加數目之至少一些在開始於該一個訊框期間的中途且連續交替地朝向一起始及朝向該一個訊框期間之一結束；及一第二像素，其中針對一增加灰階，在光通過期間，安置該第一群組之子訊框期間之增加數目之至少一些在該一個訊框期間，使得該安置關於在該第一像素中之對應子訊框期間的安置係對稱的，其中以一交替方式沿著二維安置該第一像素及該第二像素。
  8. 如請求項7之顯示裝置，其中對於各其他訊框期間切換對於該第一像素及該第二像素之子訊框期間之該安置。
  9. 如請求項7之顯示裝置，其中調整該一個訊框期間之一開始時序使得該第二群組之該等子訊框期間及具有相同長度之該等子訊框期間同時地出現在該第一像素中及該第二像素中。
  10. 如請求項1之顯示裝置，其中在導致在除了一第一子訊框期間以外之一第二子訊框期間的光通過的該存在之該灰階之一增加之前，光係在額外子訊框期間通過，而非在該第一子訊框期間通過。
  11. 一種用於一顯示裝置之控制方法，該顯示裝置包含： 一光源，其用於放射複數個顏色之光；一元件，其設置於各個像素中，用於選擇性地切換以導致從該光源放射之光之一通過或從該光源放射之光之一不通過；及一控制單元，其用於驅動各個像素之該光源及該元件以表現個別灰階以在複數個子訊框期間之各者達成光通過的一存在或光通過之一不存在，其中該複數個子訊框期間形成用於顯示一影像訊框之一個訊框期間，該控制方法特徵在於：該複數個子訊框期間分類為：一第一群組，其包括長度相同之子訊框期間；及一第二群組，其包括具有較該第一群組中的該子訊框期間之該長度還短且互不相同之長度之子訊框期間；對於該第一群組，增加開始於該一個訊框期間之中途且連續朝向該一個訊框期間的起始及結束之光通過期間之子訊框期間的數目；及在該子訊框期間之各者內提供複數個顏色光通過期間，該複數個顏色光通過期間之各者通過由該光源放射之該複數個顏色之一者。
