More Information
Summary:To provide a display device and a method for display that can display a picture input by displaying more pixels than the pixels of a display element while maintaining the level of the resolution of the picture and also can secure the gradation performance by ensuring the time for displaying a predetermined gradation.SOLUTION: A display device includes: a swing unit having an optical unit for receiving light; an actuator for swinging the swing unit; a processing unit for controlling a display element on the basis of image data; and a driving unit for driving an actuator in synchronization with processing of the processing unit. The processing unit controls the display element so that the first sub-frame groups of the sub frames of the first frame of the image data will be sequentially displayed within the time of displaying the first frame, and controls the display element so that second sub-frame groups, which are different from the first sub-frames, of the sub frames of the second frame will be sequentially displayed within the time of displaying the second frame subsequent to displaying the first frame.SELECTED DRAWING: Figure 2 【課題】表示装置および方法において、所定の階調を表示する時間を確保することで階調性能を確保しつつ、表示素子の画素数よりも多くの画素を表示して入力された映像の解像度の劣化を抑制して表示する。【解決手段】光が入射する光学部を有する揺動部と、揺動部を揺動可能なアクチュエータと、画像データに基づいて表示素子を制御する処理部と、処理部の処理に同期してアクチュエータを駆動する駆動部とを備え、処理部は、画像データの第１フレームを表示する時間内に前記第１フレームを複数分割した複数のサブフレームのうちの一部の第１サブフレーム群が順次表示されるように表示素子を制御し、第１フレームに続く第２フレームを表示する時間内に第２フレームを複数分割した複数のサブフレームのうちの一部の前記第１サブフレーム群とは異なる第２サブフレーム群が順次表示されるように表示素子を制御する。【選択図】図２
