¿Qué significa la pantalla LCD?
LCD display is abbreviated as LCD in English, and its full name is Liquid Crystal Display. It is a type of flat-panel display used for the screen display of televisions and computers. The advantages of LCD displays are low power consumption, small size, and low radiation. The LCD display uses a liquid crystal solution in two pieces of polarized materials, and the crystals are rearranged to achieve the purpose of imaging when the current passes through the liquid.

The first feature of LCD is that it can work normally only if the liquid crystal is filled between two planes with fine grooves. The grooves on these two planes are perpendicular to each other (intersect at 90 degrees). Forced into a state of 90-degree twist. As the light travels along the direction of the molecular arrangement, the light is also twisted 90 degrees when passing through the liquid crystal. But when a voltage is applied to the liquid crystal, the molecules will be re-arranged vertically, so that the light can be directed out without any twisting.
The second characteristic of LCD is that it relies on polarized filters and light itself. Natural light diverges randomly in all directions. Polarized filters are actually a series of increasingly thinner parallel lines. These lines form a net to block all the light that is not parallel to these lines. The line of the polarization filter is exactly perpendicular to the first one, so it can completely block the light that has been polarized. Only when the lines of the two filters are completely parallel, or the light itself has been twisted to match the second polarized filter, the light can penetrate.
El contenido anterior es una introducción al significado de la pantalla LCD. La pantalla LCD tiene muy poca radiación para el cuerpo humano, la pantalla es suave y no daña los ojos, y puede proteger nuestra vista. El cuerpo es delgado y ahorra espacio. En comparación con la voluminosa pantalla CRT, la pantalla LCD solo necesita un -tercio del espacio de la primera, ahorra electricidad, no genera altas temperaturas y es un producto de bajo consumo de energía. Si hay polvo en el panel de la pantalla LCD, debe operar bajo el asesoramiento de personal de mantenimiento profesional. No se limite a buscar un trapo o algo áspero para limpiarlo. La operación incorrecta puede dañar fácilmente la pantalla y dañar el panel de la pantalla LCD. .
