【摘要】：基于針孔陣列的集成成像3D顯示具有成本低,重量小,器件厚度薄,易于實現(xiàn)3D/2D轉(zhuǎn)換等優(yōu)點。針孔陣列的參數(shù)設計是集成成像3D顯示器結(jié)構(gòu)設計的關鍵之一。3D觀看視角是集成成像3D顯示的關鍵性能參數(shù)之一。本文研究針孔陣列的厚度對3D觀看視角的影響。根據(jù)針孔陣列厚度與孔徑寬度的3種取值關系,分別建立3種集成成像3D成像模型,然后根據(jù)幾何光學分別計算不同成像模型的3D觀看視角,并研制了集成成像3D顯示測試裝置。實驗結(jié)果表明針孔陣列厚度存在最優(yōu)值,且只取決于圖像元節(jié)距、針孔孔徑寬度以及針孔陣列與顯示面板的間距。針孔陣列厚度取最優(yōu)值時,顯示面板上每個圖像元中所有像素發(fā)出的光線都可以通過其對應的針孔,且每個圖像元中像素發(fā)出的光線都不能通過其他針孔,因此3D觀看視角最大,且沒有串擾圖像。針孔陣列厚度小于最優(yōu)值時,顯示面板上每個圖像元中所有像素發(fā)出的光線都可以通過其對應的針孔,但是每個圖像元中部分像素發(fā)出的光線可以通過其他針孔,因此3D觀看視角不變,但是會產(chǎn)生串擾圖像,且串擾與針孔陣列的厚度成反比。針孔陣列厚度大于最優(yōu)值時,每個圖像元中只有部分像素發(fā)出的光線可以通過其對應的針孔,雖然沒有串擾圖像,但是3D觀看視角變小,且與針孔陣列厚度的厚度成反比。
[Abstract]:Integrated imaging 3D pinhole array display has the advantages of low cost, small weight based on device thickness is thin, easy to achieve 3D/2D conversion. The design parameters of pinhole array integrated imaging 3D display structure design is one of the key.3D view is one of the key performance parameters of the integrated imaging 3D display. This paper studies the thickness of the viewing angle of the pinhole array impact on the 3D. According to the 3 kinds of relation between the pinhole array thickness and aperture width, respectively set up 3 kinds of integrated imaging 3D imaging model based on geometrical optics, then calculated the different imaging model 3D viewing angle, and developed the integrated imaging 3D display test device. The experimental results show that the thickness of pinhole array has an optimal value, and only depends on the in the image element pitch, pinhole aperture width and pinhole array and display panel spacing. The optimal thickness of pinhole array value, each pixel on the display panel diagram In the light of all pixels are available through the pinhole, and the pixel of each image element in the light cannot pass through other pinhole, so 3D maximum viewing angle, and there is no crosstalk image. Pinhole array thickness is less than the optimal value, display all pixels of each image element in a panel light can be through the the pinhole image, but each element in the part of the light emitted from the pixel through other pinhole, so the 3D viewing angle unchanged, but will produce crosstalk and crosstalk image, and pinhole arrays is inversely proportional to the thickness of pinhole array. The thickness is more than the optimal value of each image element, only part of the light emitted by the pixels corresponding to the the pinhole, although there is no crosstalk image, but 3D viewing angle becomes smaller, and the thickness is inversely proportional to the thickness of pinhole array.
