Description
本發明係有關於頭戴式顯示器,特別是有關於一種寬視角頭戴式顯示器。 This invention relates to head mounted displays, and more particularly to a wide viewing angle head mounted display.
Head Mounted Display(HMD)-頭戴式顯示器,主要可分為沉浸式(immersive)與穿透式(See-through)兩種類型。穿透式頭戴式顯示器適合用於擴增實境(Augmented Reality,AR);沉浸式頭戴式顯示器則適合用於虛擬實境(Virtual Reality,VR)。沉浸式頭戴式顯示器主要由面板顯示器與光學鏡頭等組件構成影像顯示系統。舉例來說,有機發光二極體(OLED)面板顯示器中,有許多紅、藍、綠(R、G、B)發光子像素點(Subpixel),藉由三原色子像素點組成發光像素點(pixel),最後由這些像素點發光組成影像畫面。 Head Mounted Display (HMD) - Head-mounted display, mainly divided into immersive and see-through types. Penetrating head-mounted displays are suitable for Augmented Reality (AR); immersive head-mounted displays are suitable for Virtual Reality (VR). The immersive head-mounted display mainly consists of components such as a panel display and an optical lens to form an image display system. For example, in an organic light-emitting diode (OLED) panel display, there are a plurality of red, blue, and green (R, G, B) light-emitting sub-pixels (Subpixels), which are composed of three primary color sub-pixel dots to form a pixel (pixel). ), and finally, these pixels are illuminated to form an image frame.
有部份傳統的頭戴式顯示器係採用非平行的鏡片設計,意即左眼顯示面板/鏡頭及右眼顯示面板/鏡頭之間係具有一角度差。然而,非平行的鏡片設計最大的問題在於使用者在使用頭戴式顯示器時無法配戴其個人眼鏡,也需要其他的調焦設計。此外,散光也無法調整,進而使得頭戴式顯示器之價格與重量增加,造成使用者體驗下降。 Some conventional head-mounted displays use a non-parallel lens design, meaning that there is an angular difference between the left-eye display panel/lens and the right-eye display panel/lens. However, the biggest problem with non-parallel lens designs is that users cannot wear their personal glasses when using a head-mounted display, and other focusing designs are required. In addition, astigmatism cannot be adjusted, which in turn increases the price and weight of the head-mounted display, resulting in a drop in user experience.
有鑑於此,需要一種寬視角頭戴式顯示器以解決上述問題。 In view of this, there is a need for a wide viewing angle head mounted display to solve the above problems.

為使本發明之上述目的、特徵和優點能更明顯易懂,下文特舉一較佳實施例,並配合所附圖式,作詳細說明如下。 The above described objects, features and advantages of the present invention will become more apparent from the description of the appended claims.
第1圖係顯示使用者之左眼及右眼視角範圍的示意圖。一般人的左右眼之視角大約介於94度至104度之間,且左右眼總合之視角大約為210度左右,如第1圖所示。在頭戴式顯示器中,為了讓使用者達到較佳的沈浸感須把人眼視角全部包含住。傳統的頭戴式顯示器,往往其顯示面板之顯示範圍往 往無法涵蓋使用者之左右眼之餘光範圍。此外,因為每個人的生理構造不同,有些使用者之視角範圍更為寬廣,若使用傳統的頭戴式顯示器,其使用者體驗並不佳。 Figure 1 is a schematic diagram showing the range of viewing angles of the left and right eyes of the user. The angle of view of the left and right eyes of an average person is approximately between 94 degrees and 104 degrees, and the viewing angle of the left and right eyes is approximately 210 degrees, as shown in FIG. In a head-mounted display, in order to allow the user to achieve a better immersion, the human eye angle must be included. The traditional head-mounted display often has a display range of its display panel. It is impossible to cover the range of the left and right eyes of the user. In addition, because each person's physiological structure is different, some users have a wider range of viewing angles, and the user experience is not good if a conventional head-mounted display is used.
第2圖係顯示傳統非平行鏡片設計之頭戴式顯示器的示意圖。如第2圖所示,使用非平行鏡片設計之傳統頭戴式顯示器包括了左眼顯示面板210相應的左眼鏡頭、以及右眼顯示面板220及相應的右眼鏡頭221,且使用者之可視範圍為區域250之間。左眼201及右眼202係分別透過左眼鏡頭211及右眼鏡頭221接收來自左眼顯示面板210及右眼顯示面板220所播放的左眼影像及右眼影像。 Figure 2 is a schematic diagram showing a head mounted display of a conventional non-parallel lens design. As shown in FIG. 2, a conventional head-mounted display using a non-parallel lens design includes a corresponding left-eye lens of the left-eye display panel 210, and a right-eye display panel 220 and a corresponding right-eye lens 221, and is visible to the user. The range is between areas 250. The left eye 201 and the right eye 202 receive the left eye image and the right eye image played by the left eye display panel 210 and the right eye display panel 220 through the left lens head 211 and the right eye lens 221, respectively.
需注意的是,左眼顯示面板210及右眼顯示面板220之間係具有一角度差。非平行的鏡片設計最大的問題在於使用者在使用傳統頭戴式顯示器時並無法配戴其個人眼鏡,也需要其他的調焦設計。此外,散光也無法調整,進而使得頭戴式顯示器之價格與重量增加,造成使用者體驗下降。 It should be noted that there is an angular difference between the left-eye display panel 210 and the right-eye display panel 220. The biggest problem with non-parallel lens designs is that users can't wear their personal glasses when using traditional head-mounted displays, and other focusing designs are needed. In addition, astigmatism cannot be adjusted, which in turn increases the price and weight of the head-mounted display, resulting in a drop in user experience.
此外,若使用者之左右眼的整體視角較大,則若要包含左右眼之餘光的範圍,傳統頭戴式顯示器之左眼顯示面板210及右眼顯示面板220則需大幅增加其長度,這會導致左眼顯示面板210及右眼顯示面板220的長度過長,也會大幅增加頭戴式顯示器之重量及體積。 In addition, if the overall viewing angle of the left and right eyes of the user is large, the left eye display panel 210 and the right eye display panel 220 of the conventional head mounted display need to be greatly increased in length if the range of the left and right eyes is included. This causes the lengths of the left-eye display panel 210 and the right-eye display panel 220 to be too long, which also greatly increases the weight and volume of the head-mounted display.
第3圖係顯示依據本發明一實施例中之寬視角頭戴式顯示器的方塊圖。在一實施例中,寬視角頭戴式顯示器300主要包括一外殼330、一前顯示面板310及對應的左眼鏡頭311及右眼鏡頭312、第一側顯示面板320及相應的第一側鏡頭 321、第二側顯示面板330及相應的第二側鏡頭331。其中,左眼鏡頭311及右眼鏡頭312係採用平行設計,其與前顯示面板310亦成平行。 Figure 3 is a block diagram showing a wide viewing angle head mounted display in accordance with an embodiment of the present invention. In one embodiment, the wide-view head mounted display 300 mainly includes a housing 330, a front display panel 310, and corresponding left and right lens heads 311 and 312, a first side display panel 320, and a corresponding first side lens. 321 . The second side display panel 330 and the corresponding second side lens 331 . The left lens head 311 and the right lens head 312 are in parallel design, and are also parallel to the front display panel 310.
前顯示面板310係主要用以播放來自一主控端的影像資料,例如包括左眼影像及右眼影像。左眼鏡頭311係用以將前顯示面板310之左半邊之影像經過折射投至使用者的左眼,左眼鏡頭311係用以將前顯示面板310之右半邊之影像經過折射投至使用者的右眼。 The front display panel 310 is mainly used to play image data from a main control terminal, for example, a left eye image and a right eye image. The left lens 311 is configured to refract the image of the left half of the front display panel 310 to the left eye of the user, and the left lens 311 is configured to refract the image of the right half of the front display panel 310 to the user. Right eye.
第一側顯示面板320及第二側顯示面板330係與前顯示面板310呈直角式設計,即第一側顯示面板320及第二側顯示面板330係分別安置於前顯示面板310之左眼及右側,且分別與前顯示面板310呈直角。此外,左眼鏡頭311與第一側鏡頭321亦成直角式設計,意即左眼鏡頭311與第一側鏡頭321之光軸是互相垂直。類似地,右眼鏡頭312與第二側鏡頭331亦成直角式設計,意即右眼鏡頭312與第二側鏡頭331之光軸是互相垂直。 The first side display panel 320 and the second side display panel 330 are disposed at right angles to the front display panel 310, that is, the first side display panel 320 and the second side display panel 330 are respectively disposed on the left eye of the front display panel 310 and The right side is at right angles to the front display panel 310, respectively. In addition, the left lens 311 and the first side lens 321 are also designed at right angles, that is, the optical axes of the left lens 311 and the first side lens 321 are perpendicular to each other. Similarly, the right lens 312 and the second side lens 331 are also designed at right angles, that is, the optical axes of the right lens 312 and the second lens 331 are perpendicular to each other.
第一側顯示面板320係播放前顯示面板310中之影像資料的場景之左邊延伸視角的畫面,第二側顯示面板330係播放前顯示面板310中之影像資料的場景之右邊延伸視角的畫面。 The first side display panel 320 is a screen extending from the left side of the scene of the image data in the front display panel 310, and the second side display panel 330 is a screen extending from the right side of the scene of the image data in the front display panel 310.
一般而言,使用者之左眼餘光視線340及右眼餘光視線350所能感受到的影像解析度比前方視角之畫面來得低,故第一側顯示面板320及第二側顯示面板330是為了讓使用者可感受到左右兩側仍有場景顯示,不會因為前顯示面板無法包含左右兩側之餘光,而讓使用者之沉浸感降低。因此,第一側 顯示面板320及第二側顯示面板330可不用具備如前顯示面板310一樣的高解析度(例如FullHD或4K解析度)。 Generally, the image resolution of the user's left-eye residual light sight 340 and the right-eye residual light sight 350 is lower than that of the front viewing angle, so the first side display panel 320 and the second side display panel 330 In order to let the user feel that there are still scenes on the left and right sides, it is not because the front display panel cannot contain the left and right sides of the light, and the user's immersion is reduced. Therefore, the first side The display panel 320 and the second side display panel 330 may not have the same high resolution as the front display panel 310 (for example, FullHD or 4K resolution).
第一側鏡頭321係用以將第一側顯示面板320所播放之影像經過折射投至使用者的左眼,第二側鏡頭331係用以將第二側顯示面板330所播放之影像經過折射投至使用者的右眼。舉例來說,第一側鏡頭321之解析度(或長度)需至少能涵蓋使用者之左眼餘光視線340。然而,為了能符合絕大多數使用者之生理構造,第一側鏡頭321之解析度(或長度)均會較一般使用者之餘光視角來得大。類似地,第二側鏡頭331之解析度(或長度)也會較一般使用者之餘光視角來得大。 The first side lens 321 is configured to refract the image played by the first side display panel 320 to the left eye of the user, and the second side lens 331 is configured to refract the image played by the second side display panel 330. Cast to the user's right eye. For example, the resolution (or length) of the first side lens 321 needs to cover at least the left eye residual light sight 340 of the user. However, in order to conform to the physiological structure of most users, the resolution (or length) of the first side lens 321 is larger than that of the general user. Similarly, the resolution (or length) of the second side lens 331 is also larger than that of the average user.
在一實施例中,寬視角頭戴式顯示器300更包括一傳輸介面、及一顯示控制器(第3圖中未繪示)。傳輸介面係用以從一主控端(host)接收影像資料(例如包括左眼影像及右眼影像、以及左側餘光影像及右側餘光影像,例如可為RGB影像),並將影像資料透過顯示控制器於前顯示面板310播放左眼影像及右眼影像,並於第一側顯示面板320及第二側顯示面板330分別播放左側餘光影像及右側餘光影像。舉例來說,傳輸介面可為高解析度多媒體介面(High Definition Multimedia Interface,HDMI)、或顯示埠(DisplayPort,DP)介面,但本發明並不限於此。在一些實施例中,前顯示面板310可分為一左眼顯示面板及一右眼顯示面板,且左眼顯示面板及右眼顯示面板為併排且平行的,兩者之間並無角度差。 In one embodiment, the wide viewing angle head mounted display 300 further includes a transmission interface and a display controller (not shown in FIG. 3). The transmission interface is used to receive image data from a host (for example, a left eye image and a right eye image, and a left remaining image and a right remaining image, for example, an RGB image), and the image data is transmitted through The display controller plays the left-eye image and the right-eye image on the front display panel 310, and plays the left-side residual light image and the right-side residual light image on the first side display panel 320 and the second side display panel 330, respectively. For example, the transmission interface may be a High Definition Multimedia Interface (HDMI) or a DisplayPort (DP) interface, but the invention is not limited thereto. In some embodiments, the front display panel 310 can be divided into a left eye display panel and a right eye display panel, and the left eye display panel and the right eye display panel are side by side and parallel, with no angular difference therebetween.
顯示控制器係用以控制在前顯示面板310、第一側顯示面板320、及第二側顯示面板330之顯示畫面。舉例來說, 顯示控制器可經由傳輸介面從一主控端接收影像資料,例如包括左眼影像及右眼影像、以及左側餘光影像及右側餘光影像。 The display controller is configured to control display screens of the front display panel 310, the first side display panel 320, and the second side display panel 330. for example, The display controller can receive image data from a host through a transmission interface, for example, a left eye image and a right eye image, and a left remaining image and a right remaining image.
此外,寬視角頭戴式顯示器300更包括一外殼,上述之各個光學元件及顯示面板可依前述之排列方式置於該外殼中,且該外殼可包括一束帶或其他輔助裝置(未繪示)以供使用者戴於頭上以透過寬視角頭戴式顯示器300觀賞畫面。 In addition, the wide-view head-mounted display 300 further includes a housing, and each of the optical components and the display panel may be disposed in the housing according to the foregoing arrangement, and the housing may include a strap or other auxiliary device (not shown) ) for the user to wear on the head to view the picture through the wide-view head mounted display 300.
第4圖係顯示依據本發明另一實施例中之寬視角頭戴式顯示器的方塊圖。本發明中寬視角頭戴式顯示器之設計係可讓使用者配戴眼鏡時使用,因此在設計寬視角頭戴式顯示器300中之各個元件的位置排列時,會考慮到各使用者之頭型或眼睛深度不同的問題。舉例來說,眼鏡之寬度可大約用2個鏡片寬度加上鏡橋(bridge)之寬長進行計算,例如小型/窄型臉之整體寬度約為125mm至129mm,中型臉約為130mm至134mm,大型臉約為135mm至139mm,寬型臉約為140mm至145mm,故寬視角頭戴式顯示器300中之各個元件的位置排列亦考慮到各種不同眼鏡寬度。 Figure 4 is a block diagram showing a wide viewing angle head mounted display in accordance with another embodiment of the present invention. In the present invention, the design of the wide-view head-mounted display can be used when the user wears the glasses. Therefore, when designing the position of each component in the wide-view head-mounted display 300, the head shape of each user is taken into consideration. Or a problem with different eye depths. For example, the width of the glasses can be calculated using approximately 2 lens widths plus the width of the bridge. For example, the overall width of the small/narrow face is about 125 mm to 129 mm, and the medium face is about 130 mm to 134 mm. The large face is about 135 mm to 139 mm, and the wide face is about 140 mm to 145 mm. Therefore, the positional arrangement of the various elements in the wide viewing angle head mounted display 300 also takes into account various different eyeglass widths.
舉例來說,使用者可利用寬視角頭戴式顯示器300中之機構(未繪示)以調整第一側顯示面板320及相應的第一側鏡頭321、以及第二側顯示面板330及相應的第二側鏡頭331的偏移量。 For example, the user can utilize the mechanism (not shown) in the wide-view head mounted display 300 to adjust the first side display panel 320 and the corresponding first side lens 321 and the second side display panel 330 and corresponding The offset of the second side lens 331.
更進一步而言,第一側顯示面板320及相應的第一側鏡頭321之位置可整體於水平方向的一預定範圍內進行調整,第二側顯示面板330及相應的第二側鏡頭331之位置可整體於水平方向的一預定範圍內進行調整。 Furthermore, the positions of the first side display panel 320 and the corresponding first side lens 321 can be adjusted within a predetermined range of the horizontal direction, and the positions of the second side display panel 330 and the corresponding second side lens 331 The adjustment can be made overall within a predetermined range in the horizontal direction.
舉例來說,若使用者之餘光視角較大,例如第4圖中之左眼餘光視線341及右眼餘光視線351所示,則該使用者可將第一側顯示面板320及相應的第一側鏡頭321、以及第二側顯示面板330及相應的第二側鏡頭331調整為較接近使用者頭部,進而讓第一側顯示面板320及第二側顯示面板330之顯示範圍得以涵蓋該使用者之左眼餘光視線341及右眼餘光視線351。 For example, if the user's residual light angle of view is large, such as the left eye residual light sight 341 and the right eye residual light sight 351 in FIG. 4, the user can display the first side display panel 320 and corresponding The first side lens 321 and the second side display panel 330 and the corresponding second side lens 331 are adjusted to be closer to the user's head, thereby allowing the display range of the first side display panel 320 and the second side display panel 330 to be displayed. The left eye residual light sight 341 and the right eye residual light sight 351 of the user are covered.
第5圖係顯示依據本發明另一實施例中之寬視角頭戴式顯示器的方塊圖。寬視角頭戴式顯示器500中之各元件大致上係跟寬視角頭戴式顯示器300之元件類似,其差別在於在寬視角頭戴式顯示器300中之鏡頭311、312、321、及331可用一體成形之鏡頭模組313所取代。需注意的是,雖然鏡頭模組313是一體成形,但其光學結構仍是分別針對前顯示面板310(包括折射左眼影像及右眼影像)、第一側顯示面板320(包括折射左側餘光影像)、以及第二側顯示面板330(包括折射右側餘光影像)。在一些實施例中,前顯示面板310係可用可撓式面板實現,意即可撓式面板之表面曲度係相應於鏡頭模組313之表面曲度,且使用者可透過鏡頭模組313完整看到全景畫面影像,達到更佳的沉浸感。 Figure 5 is a block diagram showing a wide viewing angle head mounted display in accordance with another embodiment of the present invention. The components of the wide viewing angle head mounted display 500 are generally similar to the components of the wide viewing angle head mounted display 300, with the difference that the lenses 311, 312, 321, and 331 in the wide viewing angle head mounted display 300 can be integrated. The formed lens module 313 is replaced. It should be noted that although the lens module 313 is integrally formed, the optical structure is still for the front display panel 310 (including the refraction of the left eye image and the right eye image), and the first side display panel 320 (including the refraction of the left side of the backlight). The image) and the second side display panel 330 (including the refracted right side residual image). In some embodiments, the front display panel 310 can be implemented by a flexible panel. The surface curvature of the flexible panel corresponds to the surface curvature of the lens module 313, and the user can complete through the lens module 313. See the panoramic image for a better immersion.
