Basics: Photons in LCDs

LCDs (Liquid Crystal Displays) essentially work via:

  1. Backlight: usually LEDs that generate photons.

  2. Polarizing filters: only allow certain vibration directions of light to pass through.

  3. Liquid crystals: These change their molecular structure through electric fields, which influences the polarization direction of the passing light.

  4. Color filters: Divide white light into RGB.

The photons themselves do not originate from the LCD material, but are modulated by the display, not emitted.

? Theoretical question: "Transportation of photons from LCD crystals"

If we understand "transport" not as the mere transmission of light, but as the targeted exfiltration or coupling of photons from the crystal structure, there are three theoretical approaches:

1. Photon binding to crystalline states

Photons are actually massless particles and do not bind to matter in the classical way.

But in solids, quasiparticles such as excitons, polaritons, or phonon-photon couplings can occur.

Under certain conditions, liquid crystals could bind photons in the form of polaritons—e.g., through strong coupling of light and molecular vibration.

These could theoretically be "released" from the crystal.

are:

? Thought experiment: Targeted excitation of the liquid crystal with terahertz radiation changes the dipole structure in such a way that photon-like states "detach" and could be transported further along a fiber guide.

2. Photon Emulation through Crystal Structure Change

If the molecular structure of the liquid crystals is deliberately altered (electrically, thermally, or psionic in the sci‑fi sense), it could lead to the generation of coherent radiation – similar to the laser effect in organic materials.

3. Quantum Teleportation of Photon States from Crystals

In quantum optics, work is being done on teleporting photon states (not the photon itself!).

Assuming a photon state is detected in the LCD crystal (e.g., polarization or phase), this state could be recreated via entangled photons outside the crystal.

? Fiction meets physics:
A new generation of displays uses entangled crystal cells, in which each liquid crystal is coupled to an external photon sensor. When a pixel is activated, not only is light modulated, but a quantum state is teletransported.

? Conclusion (in 3 versions):

Perspective Description
? Physically realistic LCDs do not transport photons "out" of crystals, but rather modulate them. Transport occurs through classical light conduction.
? Advanced Speculative It would be conceivable to generate polaritons coupled with liquid crystals and to extract them specifically through excitation.
? Quantum Speculative / Sci-Fi Using quantum entanglement and crystal lattice interference, photon states could be teleported, which would be a completely new form of photonic communication.

The theoretical transport of photons from LCD crystals (liquid crystal displays) is a highly interesting line of thought that touches on optical physics, materials science, and possibly quantum optics.

To mentally explore this process, one must understand how LCDs actually handle photons – and what “transportation” might mean?
