Which of the following display technologies are classified as transmissive?

LCD (Liquid Crystal Display) technology is classified as transmissive because it relies on a backlight that shines through liquid crystals to display images. In a transmissive display, the light emitted from the backlight passes through the liquid crystals, which modulate the light based on the input signal, allowing varying degrees of light to pass through to create images. This is a fundamental characteristic of how LCD technology functions, making it a primary example of transmissive display technology.

In contrast, LED (Light Emitting Diode) displays, while they use LEDs for illumination, can be either transmissive or emissive depending on their design. Plasma screens use a different technology that relies on ionized gases and are considered emissive, meaning they generate their own light rather than relying on transmitted light. Projection technologies also do not classify strictly as transmissive or emissive, as they depend on a light source that projects images onto a surface rather than generating images internally.
