頭戴式顯示器、顯示裝置及其影像顯示方法Head-mounted display, display device and image display method

本發明是有關於一種頭戴式顯示器、顯示裝置及其影像顯示方法，且特別是有關於一種複合式光場(light field)顯示系統的頭戴式顯示器、顯示裝置及其影像顯示方法。The present invention relates to a head-mounted display, a display device and an image display method thereof, and in particular, to a head-mounted display, a display device and an image display method of a composite light field display system.

隨著電子科技的進步，一種光場顯示器被提出。常見的光場顯示器大致分為五大類，高速旋轉式(High Speed Spin)、多投影機式(Multi-Projector)、指向性背光式(Directional Backlight)、多層顯示器式(Multi Layer Display)及透鏡陣列式(Lens Array)。With the advancement of electronic technology, a light field display has been proposed. Common light field displays are roughly divided into five categories: High Speed Spin, Multi-Projector, Directional Backlight, Multi Layer Display and Lens Array Formula (Lens Array).

在習知技術領域中，特別是在透鏡陣列式的光場顯示器中，其最主要的問題在於解析度無法有效的被提升。因此，如何提升光場顯示器的解析度以提升使用者的影像體驗度，是本領域技術人員的重要課題。In the conventional technical field, especially in the lens array type light field display, the main problem is that the resolution cannot be effectively improved. Therefore, how to improve the resolution of the light field display to enhance the user's image experience is an important issue for those skilled in the art.

本發明提供一種頭戴式顯示器、顯示裝置及其影像顯示方法，可提升影像的顯示效果。The present invention provides a head-mounted display, a display device and an image display method thereof, which can improve the display effect of images.

本發明的顯示裝置包括第一顯示器以及第二顯示器。第一顯示器用以提供第一顯示影像至目標區的週邊區域。第二顯示器提供第二顯示影像至目標區的中心區域。其中第二顯示影像的解析度大於第一顯示影像的解析度。The display device of the present invention includes a first display and a second display. The first display is used to provide a first display image to the peripheral area of the target area. The second display provides a second display image to the center area of the target area. The resolution of the second display image is greater than the resolution of the first display image.

本發明的頭戴式顯示裝置包括本體部以及如上所述的顯示裝置。其中的顯示裝置設置在本體部中。The head-mounted display device of the present invention includes a main body and the display device as described above. The display device is arranged in the main body.

本發明的影像顯示方法包括：使第一顯示器提供第一顯示影像至目標區的週邊區域；使第二顯示器，提供第二顯示影像至目標區的中心區域；使第二顯示影像的解析度大於第一顯示影像的解析度。The image display method of the present invention includes: making the first display provide a first display image to the peripheral area of the target area; making the second display provide a second display image to the central area of the target area; making the resolution of the second display image be greater than The first displays the resolution of the image.

基於上述，本發明透過第二顯示器，以在人眼注意力相對集中的目標區的中心區域中提通具有相對高解析度的第二顯示影像。而在目標區的週邊區域，則透過第一顯示器來提供具有相對低解析度的第一顯示影像。如此一來，在光場顯示系統中，本發明的顯示裝置可有效提高影像的顯示品質。在頭戴式顯示器的應用中，可有效提升虛擬影像的顯示效能。Based on the above, the present invention uses the second display to provide a second display image with relatively high resolution in the central area of the target area where human eyes' attention is relatively concentrated. In the peripheral area of the target area, a first display image with a relatively low resolution is provided through the first display. In this way, in a light field display system, the display device of the present invention can effectively improve the display quality of images. In the application of head-mounted displays, the display performance of virtual images can be effectively improved.
