85 "HD LCD Panel Naked Eye 3D Advertising Display
There are many products about advertising machines on the market at present, do you know the difference between 3D holographic advertising machines and LED displays? 3D advertising machine is a brand-new display product. It is an aerial phantom media display device that uses LED light bars to rotate and display, and uses the principle of human eye persistence to form graphics, animations and videos. Because the product has no frame and background, users feel that the image is three-dimensional floating, so it is also called holographic display and fan screen. What is the difference between a 3D holographic advertising machine and an LED display? , Let Chuangxinwei Xiaobian share it with you today, and summarize it in one sentence: Compared with the previous LED display, the 3D holographic advertising machine is far superior to the traditional LED display in all aspects.
1.Adopt 85 inch HD LCD panel, physical resolution up to 3840×2160, support 4K signal input.
2. It adopted DLED back light source with good uniformity and color reduction, without black edges and dark shadows.
3, the LCD screen needs to have high resolution, high brightness, high contrast, better color saturation, the requirement of true color restoration.
4, LCD screen contrast requirements ≥3000:1, screen brightness ≥250cd per square meter.
5, LCD screen to ensure uniform brightness, clear display, small image distortion, image does not flicker, can meet 7×24 hours long use, life is not less than 50000 hours.
6, with advanced, stability and scalability characteristics, simple operation, stable and reliable work.
7. Adopt two point-to-point precision laminating and fully automated optical alignment fully laminating technology to effectively improve the grating laminating accuracy.
8, the use of high permeability cylindrical lens diaphragm, transmittance is not less than 95%, surface hardness is not less than 3H.
9, the best viewing distance >0.5 meters, support adjustable, horizontal direction 3D viewing Angle 150°.
10. Using multi-view algorithm technology, image generation and display are not less than 56 view points.
11, built-in horn, power ≥5W, high sound quality and high sensitivity.
12. Support 2D+Z, left and right, up and down 3D format, depth of field effect can be adjusted.
13. Support remote control to switch different 3D formats or one button to switch different signal sources.
14, HDMI HD interface, to ensure the access of all kinds of signal sources.
15. The lower layer of the flat-column lens array is PMMA substrate, with a thickness of c=0.188mm and a refractive index of 1.56.
16. 3D crosstalk rate is less than 3.58%
17, the overall machining error accuracy should be less than 15 microns, surface roughness is less than 5 microns.
18. The optical dispersion spot corresponding to a 0 degree Angle should be less than 20 microns, the optical dispersion spot corresponding to a 25 degree Angle should be less than 25 microns, and the optical dispersion spot corresponding to a 50 degree Angle should be less than 30 microns.
19, lens distortion is not more than 6%, wave aberration is not more than 1 wavelength.
20. After the processed grating array is fitted to the LCD display, the viewing Angle of multiple people should reach more than 100 degrees, and clear 3D images can be viewed at any position within the field of view; Under the premise of no human eye tracking device, when the observer moves from the left side of the above viewing area to the right side, he can view the three-dimensional image with correct parallax and continuous perspective relation (that is, there is no repetition of parallax relation and no jump of three-dimensional image during the movement of the above viewing area).
21, the use of advanced color engine, automatic image enhancement, 3D video noise reduction, 3D video decoding and chroma separation, 3D motion adaptive, video interlacing, edge direction adaptive.
