Description
本發明係關於顯示系統之領域,特別地係指一種應用於頭戴式顯示裝置之顯示系統。The present invention relates to the field of display systems, in particular, to a display system applied to a head-mounted display device.
虛擬實境(virtual reality, VR)以及擴增實境(augmented reality, AR)的相關光學技術,近年來不只備受全球關注,更是以相當快的速度發展;此外,在現實生活中亦展現多元的應用潛力,舉凡娛樂、醫學、家居乃至於軍事等領域皆能看到藉由虛擬實境以及擴增實境技術所達成的產品或服務。Optical technologies related to virtual reality (VR) and augmented reality (AR) have not only attracted global attention in recent years, but also developed at a very fast speed; in addition, they have also been shown in real life. Diverse application potential, such as entertainment, medicine, home furnishing and even military fields, can see products or services achieved by virtual reality and augmented reality technology.
虛擬實境以及擴增實境的應用實例包括各類型的顯示裝置,例如:近眼顯示裝置或是頭戴式顯示裝置(head-mounted display, HMD)。所謂近眼顯示裝置外形類似眼鏡,亦可稱為眼鏡式顯示器、影像眼鏡或是頭戴式顯示裝置,其主要可由一承載部以及安裝於該承載部內的一顯示系統所構成;而為了能夠在達到良好的光學效果下,同時能夠兼具產品輕巧的優點,顯示系統的設置細節即成為了本領域相當重要的研發重點。Application examples of virtual reality and augmented reality include various types of display devices, such as a near-eye display device or a head-mounted display (HMD). The so-called near-eye display device is similar in appearance to glasses, and can also be called a glasses-type display, video glasses or head-mounted display device. It is mainly composed of a carrying part and a display system installed in the carrying part; With good optical effects and the advantages of lightness and lightness, the setting details of the display system have become a very important research and development focus in this field.
以目前常見,且應用於頭戴式顯示裝置的顯示系統而言,可以大致區分為透鏡式或者光波導式。透鏡式的顯示系統實質上涉及複雜的光學系統設置,且製作的技術門檻亦較高。然而就光波導式來說,其概念上即藉由光的全反射原理將顯示器產生的圖/影像傳遞至人眼;基於此特性而製成的頭戴式顯示裝置因為能將顯示器旁置,進而大大降低系統元件對外在光的遮蔽,且能另顯示裝置更為輕薄。For display systems currently common and applied to head-mounted display devices, they can be roughly classified into lens type or optical waveguide type. The lens-type display system essentially involves complex optical system settings, and the technical threshold for production is also relatively high. However, for the optical waveguide type, the concept is to transmit the image/image generated by the display to the human eye through the principle of total reflection of light; the head-mounted display device made based on this characteristic can place the display next to it, Further, the shielding of the system components from external light is greatly reduced, and the display device can be made thinner and lighter.
然而進一步而言,一般光波導式的頭戴式顯示裝置若要增設3D顯示的功能時,可能需要額外的製程或元件;因此可以理解,如何以較為簡單且成本較低的方式設計一具有3D顯示效果之光波導式顯示裝置,實屬一頭戴式顯示裝置相關領域中亟需被解決的問題。However, further, when adding a 3D display function to a general optical waveguide head-mounted display device, additional processes or components may be required. Therefore, it is understandable how to design a 3D display device in a simpler and lower cost manner. The optical waveguide type display device with the display effect is a problem that needs to be solved urgently in the related field of the head-mounted display device.
