A holographic display is a type of 3D display that utilizes light diffraction to display a three-dimensional image to the viewer. Holographic displays are distinguished from other forms of 3D displays in that they do not require the viewer to wear any special glasses or use external equipment to be able to see the image, and do not cause a vergence-accommodation conflict.
Electrically operated display devices have developed from electromechanical systems for display of text, up to all-electronic devices capable of full-motion 3D color graphic displays. Electromagnetic devices, using a solenoid coil to control a visible flag or flap, were the earliest type, and were used for text displays such as stock market ...
The first display application was a cube suspended in the air in front of the user. The system itself consisted of six subsystems: a clipping divider , matrix multiplier , vector generator , headset, head-position sensor , and a general-purpose computer – which would make these the components of the first virtual reality machine as we know ...
The 1960s weren’t just about rock ‘n’ roll and Vietnam War protests; they were also the birthplace of cutting-edge electronics that defined a generation. From sleek transistor radios to ...
Holographic optical element (HOE) is an optical component (mirror, lens, directional diffuser, etc.) that produces holographic images using principles of diffraction.HOE is most commonly used in transparent displays, 3D imaging, and certain scanning technologies.

A holographic screen is a two-dimensional display technology that uses coated glass media for the projection surface of a video projector. "Holographic" refers not to a stereoscopic effect, but to the coating that bundles light using formed microlenses. The lens design and attributes match the holographic area.
