Description
本發明涉及一種3D立體影像顯示裝置,尤指一種免設置透鏡陣列的3D立體影像顯示裝置。The present invention relates to a 3D stereoscopic image display device, in particular to a 3D stereoscopic image display device without a lens array.
現有的立體影像顯示裝置,一般主流採用雙眼融合影像的技術製成。一般裸視立體影像顯示裝置,皆讓觀賞者在正對顯示裝置的角度觀看,抑或影像深度不能遠離顯示面太多。然而在考慮一些情境狀況的場合裡,例如航空地形模型、建築模型、醫療3D訓練等,顯示裝置為水平擺放的情況時,觀賞者自然的視角為斜向的觀看顯示裝置。此時一般主流的立體影像顯示技術無法提供對觀賞者自然的觀看角度,造成不便。再者,一般立體影像顯示裝置,在正面所觀看的3D感知,對觀賞者來說是只有一個方向的視覺刺激,就像是畫面突出或沉入,而無法達到真正讓影像脫離平面的感覺,實現漂浮於空中的感覺。Existing stereoscopic image display devices are generally made by the technology of binocular fusion of images. Generally, the naked-view stereoscopic image display device allows the viewer to watch from an angle facing the display device, or the depth of the image cannot be too far from the display surface. However, when considering some situational situations, such as aviation terrain models, architectural models, medical 3D training, etc., when the display device is placed horizontally, the natural viewing angle of the viewer is to view the display device obliquely. At this time, the general mainstream stereoscopic image display technology cannot provide the viewer with a natural viewing angle, which causes inconvenience. Furthermore, for a general stereoscopic image display device, the 3D perception viewed from the front is a visual stimulus in only one direction for the viewer, just like the image protruding or sinking in, and it cannot achieve the feeling that the image is out of plane. Realize the feeling of floating in the air.
台灣專利公告號第I614533號揭示一種立體顯示裝置,包括一平面顯示裝置、一透鏡陣列層及一微結構層,平面顯示裝置具有一顯示面,透鏡陣列層設置於平面顯示裝置的顯示面上,透鏡陣列層包含一基部及數個具有聚焦功能的透鏡,透鏡陣列層用於調控光場,微結構層設置於透鏡陣列層上,微結構層包含一基材及數個微結構,微結構層用於調變光線角度方向。藉此,用於顯現漂浮於空中的立體影像,且能在斜向的視角觀賞。然而現有的立體顯示裝置,大多需要設置透鏡陣列,使其成本無法進一步的降低。另外,透鏡本身會有像差,造成影像品質下降,且製程上亦會受限。另,由於透鏡陣列做成大片於製程難度很高,因此不便於大尺寸的應用,且一般使用透鏡陣列的集成式影像於大視角會有其他階錯誤的影像,難以提升影像品質。Taiwan Patent Publication No. I614533 discloses a stereoscopic display device, comprising a flat display device, a lens array layer and a microstructure layer, the flat display device has a display surface, and the lens array layer is disposed on the display surface of the flat display device, The lens array layer includes a base and several lenses with focusing functions.

[第一實施例][First Embodiment]
本發明提供一種3D立體影像顯示裝置,其可應用於例如光電、醫療、軍事、展示、顯示器、教育娛樂及消費型電子等各種產業,該3D立體影像顯示裝置可應用於主動式或被動式等顯示器,並不予以限制。The present invention provides a 3D stereoscopic image display device, which can be applied to various industries such as optoelectronics, medical treatment, military, display, display, education and entertainment, and consumer electronics. The 3D stereoscopic image display device can be applied to active or passive displays. , without limitation.
請參閱圖1,本發明3D立體影像顯示裝置包括一顯示模組1、一背光模組2及一圖像演算單元3,該顯示模組1具有一顯示面11,在本實施例中,該顯示模組1為一具有彩色濾光片(Color Filter)的液晶面板,該顯示模組1具有多個像素,能利用軟體的方式來打開多個需要使用的像素12及關掉多個不需要使用的像素13,該些需要使用的像素12間隔的設置。該顯示模組1具有調控光場的功效,該顯示模組1可以調控立體物件的光線角度,讓原本尚未重組的平面影像進行重新分配和組合,進而讓觀賞者看到三維立體影像。該些需要使用的像素12的直徑、高度,以及與背光模組2的間距,可適當的予以變化,用以決定立體影像的高度、可視角度範圍及清晰度等三維影像內容。該些需要使用的像素12對顯示的效果有關聯,其排列方式可為矩形排列或六角形排列的方式,亦即每相鄰兩列的需要使用的像素12可呈相對的排列或交錯的排列,皆可用以顯示3D影像資訊。Please refer to FIG. 1 , the 3D stereoscopic image display device of the present invention includes a display module 1 , a
該背光模組2設置於顯示模組1的一側,在本實施例中,該背光模組2間隔的設置於顯示模組1遠離顯示面11的一側,該背光模組2可投射出光源,使光線透過顯示模組1後,將資訊傳遞到使用者的眼中。該背光模組2包含多個光源21,該些光源21可為LED或OLED等光源,該些光源21可為點光源或面光源。在本實施例中,該些光源21為白光光源,該些光源21間隔的設置,該些光源21可提供如同針孔陣列層的功能,該些光源21可分別與該些需要使用的像素12相對應。該圖像演算單元3電性連接於顯示模組1及背光模組2。平面圖像可透過該些光源21及顯示模組1,進而顯示重組的三維立體影像。The
本發明可用於斜向觀賞三維立體影像,所謂斜向觀賞的方式是指觀賞者並非正對顯示模組1,但也能看到立體影像。在傳統的裸眼式三維立體顯示中,絕大多數有觀賞視角的問題,而讓觀賞者不能在斜向的角度看到。在本發明中,斜向觀賞反而是一大特點,觀賞者在正對顯示模組1的方向上(zero order viewing zone),而左右分別有一段可觀賞的視角限制,一旦超出此視角,則觀賞者看到的將不是相對應所在角度應該看到的立體資訊。為達到斜向觀賞立體影像,不再採用0階(正向)的顯示方式,而是採用斜向角度的顯示方式,將光路徑匯聚到斜向的方向上,而讓觀賞者可以在該斜向的方向上觀賞立體影像。惟,本發明的3D立體影像顯示裝置同樣可應用於正向的角度觀看立體影像。The present invention can be used for oblique viewing of three-dimensional images. The so-called oblique viewing mode means that the viewer is not facing the display module 1 directly, but can also see the three-dimensional images. In the traditional naked-eye three-dimensional display, most of them have the problem of viewing angle, so that the viewer cannot see it at an oblique angle. In the present invention, oblique viewing is a major feature. The viewer is in the direction facing the display module 1 (zero order viewing zone), and there is a viewing angle limit on the left and right sides. What the viewer sees will not be the stereoscopic information that should be seen at the corresponding angle. In order to achieve oblique viewing of stereoscopic images, the 0-order (forward) display method is no longer used, but the oblique angle display method is used to focus the light path in the oblique direction, so that the viewer can watch the oblique direction. to view the stereoscopic image in the direction of . However, the 3D stereoscopic image display device of the present invention can also be applied to viewing stereoscopic images from a positive angle.
本發明的顯示模組1可以為任意規格,只要能讓演算法則適用即可,亦即該顯示模組1電性連接有圖像演算單元3,使用於顯示模組1的圖像需要經過圖像演算法的計算,此計算搭配背光模組2的架構,預知其光線行走的各種路徑,而計算圖像相對位置。由於圖像演算法為現有技術,且非本發明訴求的重點,故不再加以贅述。The display module 1 of the present invention can be of any specification, as long as the algorithm can be applied, that is, the display module 1 is electrically connected with the
是以,本發明提出一種可以適用於正向、斜向觀賞角度的3D立體影像顯示裝置,配合硬體設置,可控制裝置中各個位置像素的光線行進方向。本發明硬體系統為簡易光學元件,包括顯示模組1、背光模組2及圖像演算單元3,可封裝成一個套件,藉由設計好的像素大小、系統間隙及焦距,利用集成式影像原理,搭配經過特殊演算法的螢幕輸出畫面訊號,可以使其呈現實像在立體空間之中。本發明在硬體特點上,不需要其他光學膜片,只要顯示模組1、背光模組2及圖像演算單元3,極其簡單的裝置,就可以達到懸浮圖像的效果,用於顯現漂浮於空中的立體影像。Therefore, the present invention proposes a 3D stereoscopic image display device which can be applied to forward and oblique viewing angles, and can control the light traveling direction of each position pixel in the device in cooperation with the hardware setting.
