Integral Imaging With Full Parallax Based on Mini LED Display Unit

Abstract

Integral imaging has been considered as the most applicable technology of true 3D display in the near future. In this paper, we propose the method to achieve full parallax and large-screen integral imaging display based on mini LED. Compared to the existing integral imaging systems based on the LED, the proposed method can present both horizontal and vertical parallaxes. We explore the optical parameter matching method between mini LED display unit and lenslet unit and design three different shapes of lenslet arrays. The imaging performance of lenslet arrays of circular-shape, square-shape, and hexagonal-shape is analyzed. The method of window interception is proposed to generate elemental images for the lenslet arrays with different apertures and arranging structures. The experimental results show that the true 3D display with full parallax and screen scalability has been realized using the proposed method and the display effect of lenslet array with hexagonal-shape is the best according to the evaluation of both subjective and objective merits.

Real–Virtual 3D Scene-Fused Integral Imaging Based on Improved SuperPoint

“…The process of collecting and visualizing spatial scene information using an integral imaging system can be summarized as consisting of two stages: acquisition and display, as shown in Figure 4a [5]. During the acquisition process, media with information Import the real object model into virtual space and combine it with a virtual model, and a virtual reality fusion scene is created.…”

“…It has been developed for more than a century. Many researchers have dedicated their efforts to improving the 3D display performance in various aspects [2][3][4][5]. Lim et al used depth-slice images and orthogonal-view images to optimize element image arrays and enhance the display resolution [6].…”

“…27,28 Each light-emitting unit in a large-area region can be controlled independently in this kind of technology resulting in high-contrast displays, and high-quality luminous materials help to realize the high-purity color and the wide color gamut. 29–31 But the industry procedure and technology are not mature now, and they still face problems in realizing both stable materials and low-cost manufacturing.…”

64‐4: Student Paper: MiniLED Driving Circuit with Power‐Saving Mechanism for Use in LCD Backlight Module

“…OLED displays have high contrast ratio since the OLED is a self-emissive component, however the OLED are made of organic materials which would cause image burn-in after degradation [4], [5]. To solve the issues of the mainstream display, the Mini-LED is applied to the active matrix backplane of the LCD to accomplish local dimming which increases the contrast ratio of the display [6], [7]. To generate uniform image for the display, the threshold voltage (VTH) variation of the lowtemperature poly-crystalline silicon thin-film transistor (LTPS TFT) in the driving circuit must be compensated [8], [9].…”
