Plasma TV self-luminous principle advantages

Plasma TV self-illumination refers to its working principle, and is the best technology to restore natural colors in the current TV display technology. Plasma TVs use a large number of plasma tubes arranged together to form a screen. Each cell corresponding to each plasma is filled with neon and xenon gas. The gas activates the red, green and blue phosphors on the display to emit visible light through voltage to form a picture. The working principle of plasma self-illumination mainly has the following benefits:

1. High color reproduction. Since the plasma TV adopts self-illumination imaging method instead of passive light emission, it has higher color saturation, richer color types, better color reproduction, clearer image layers, and natural and more realistic picture performance. As comfortable as viewing natural objects.

2. High dynamic clarity. Let ’s talk about the passive light imaging method first. Taking the LCD TV as an example, it relies on the rotation of the liquid crystal in the liquid crystal panel to control the passage of light to form an image, and the rotation of the liquid crystal (that is, the pixel changes from dark to bright or from bright to dark). A process requires a reaction time, so there is a lag in the display of the picture when it tells the dynamic picture, which is also called the "tailing" phenomenon of the liquid crystal. In contrast, the automatic light-emitting imaging method does not require a reaction time, and there is no lag even when expressing a dynamic picture, and the dynamic clarity is naturally higher.

3. Wide viewing angle. Since each plasma of the plasma TV has a corresponding light-emitting point, and each point is an independent light-emitting body, no matter what angle is viewed, the screen of the plasma TV will not be distorted or blurred.

4. High visual comfort. The plasma TV is imaged by self-active light emission, so the brightness of the picture is soft, and it will not easily cause eye fatigue because of too high brightness. The self-luminescence makes the plasma TV have strong color reproduction ability, natural color and high fidelity, which will not bring strong stimulation to the eyes and is more conducive to protecting the eyes. And the dynamic picture of plasma TV does not trail, the visual experience is more comfortable.

5. High contrast. As mentioned above, the principle of plasma self-illumination makes its color reproduction higher and color expressive. An important indicator to measure the effect of the TV is the performance of black. The more advanced the TV, the blacker and purer the black will be. The good expressiveness of black is the manifestation of high contrast. At present, the highest contrast ratio of plasma TV can reach 10000: 1. In terms of the performance of black, plasma has an absolute advantage.
