Problems solved by technology

As mentioned above, the existing electronic holographic display technology is limited by the limit resolution of the display device, and there is still an order of magnitude difference from the requirements for describing holographic stripes; and the amount of image information is too large, so it is necessary to develop new technologies to break through. Barriers to Resolution of Existing Electron Holographic Displays

[0025] Specific implementation mode 1: Transmissive ultra-high resolution electronic holographic display device

[0026] image 3 It is a schematic diagram of a transmissive electronic holographic display device manufactured according to the technical solution of the present invention. A 100 nm thick ITO film was deposited by sputtering on the fused silica substrate 310 and carved into strip patterns with a width of 0.8 microns and a pitch of 0.2 microns as the bottom electrode 320 . Then a nano-PLZT (lanthanum-doped lead zirconate titanate) thin film 340 with a thickness of 500 nm and an average grain size of 60 nm is prepared thereon. Finally, a transparent ITO film is deposited and etched to form upper electrodes 330 with a width of 0.8 microns and a pitch of 0.2 microns. This constitutes a transmissive electro-holographic display device 300 . By controlling the voltage of each pixel point on the holographic display device through the computer interface and the driving c...

[0027] Specific implementation mode two: reflective ultra-high resolution electronic holographic display device

[0028] Figure 4 It is a schematic diagram of a reflective electronic holographic display device manufactured according to the technical solution of the present invention. After the silicon substrate 310 is thermally oxidized, a Pt / Ti film with a thickness of 50 nanometers is deposited by sputtering and carved into strip patterns with a width of 0.8 microns and a pitch of 0.2 microns as the row electrodes 320 . Then a nano SBN (strontium barium niobate) film 340 with a thickness of 600 nanometers and an average grain size of 80 nanometers is prepared thereon. Finally, a transparent ITO film is deposited and etched to form column electrodes 330 with a width of 0.8 microns and a pitch of 0.2 microns. This constitutes a reflective ultra-high resolution (1000 lines / mm) electronic holographic element 300 . By controlling the voltage of each pixel point on the hologra...

Abstract

An electronic holographic display component consists of base plate, bottom electrode, display material and top electrode. It features that said display material is prepared from transparent memory material of nanoferroelectric bend.

Description

technical field [0001] The invention belongs to the technical field of electronic display, in particular to an electronic holographic display device. Background technique [0002] The basic function of the display is to accurately and comfortably convey natural visual space or artificial visual information to people. The most ideal display can enable people to mobilize all human visual functions (such as depth perception, convergence, focus adjustment and motion parallax perception) as if they were watching nature directly. No matter how sophisticated the existing display technology is, it only keeps people's vision in the two-dimensional world of the plane, making the image displayed by the existing display lack a sense of three-dimensionality and realism; and an existing three-dimensional The display technology adopts the principle of binocular parallax to make the image have a certain three-dimensional effect, but it still does not have the function of motion parallax, w...
