Que signifie l'affichage 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.
Le contenu ci-dessus est une introduction à la signification de l'écran LCD. L'écran LCD a très peu de rayonnement sur le corps humain, l'écran est doux et ne blesse pas les yeux, et il peut protéger notre vue. Le corps est mince et économise de l'espace. Comparé à l'écran CRT volumineux, l'écran LCD n'a besoin que d'un-tiers de l'espace de l'ancien, économise de l'électricité, ne génère pas de température élevée et est un produit à faible consommation d'énergie. S'il y a de la poussière sur le panneau d'affichage LCD, vous devez opérer sous les conseils d'un personnel de maintenance professionnel. Ne vous contentez pas de trouver un chiffon ou un objet rugueux pour l'essuyer. Une mauvaise utilisation peut facilement endommager l'affichage et endommager le panneau d'affichage LCD. .
