LCD uses two pieces of polarizing material.
between them is a liquid crystal solution.
when electric current passes through the liquid, the crystals rearrange.
so that light cannot pass through them.
each crystal is like a hundred The development of LCD technology is just in line with the current trend of information products.
right angle display, low power consumption, small size, zero radiation and other advantages can make users enjoy the best visual environment.

plasma display panel is also called plasma display, It is a kind of flat display screen, the light is emitted from the ions between two pieces of glass to phosphorus.
the emitted gas has no mercury component.
instead, it is made of inert gas neon and xenon, which is harmless gas.

when viewing in a bright environment,
the brightness ratio is slightly lower than that of the LCD.
when the static plasma display screen is displayed for a long time,
it is easy to generate residual shadow when the screen is switched.
