Not only is the transparency rate involved, but the fundamental difference lies in the visual presence. Many people mistakenly believe that the holographic screen is a "high-transparency version of a transparent screen", which is a typical cognitive error. The core difference between the two lies in the visual purity of the holographic screen state.

The ordinary LED transparent screen relies on a strip-shaped PCB substrate to carry the light-emitting diodes and achieves light transmission through the gaps between the light strips. Even if the transparency rate is high in terms of parameters, in the off-screen state, one can still clearly see the outline of the light strips, the connection nodes, and the wiring traces. The device has a strong attribute and the grid effect when viewed closely is quite obvious.

However, the LED holographic screen is an advanced form after optimizing the structure, substrate, and process: using micro-sized thin light strips, optical-grade high-transparency substrate, and combined with the invisible wiring process on the entire surface, it significantly reduces the visual proportion of the display structure. In the off-screen state, the traces of the light strips are extremely faint, and the visual effect is highly similar to the original clear glass, making it almost impossible to notice that it is an electronic display device; when lit up, the picture presents a floating sensation, the boundary between the virtual and real is more gentle, and there is no harsh screen-cutting sensation.

In simple terms, the ordinary transparent screen is a "screen that can transmit light", while the holographic screen is a "glass that can display". There is an essential difference in the visual presence and spatial integration degree between the two.
