Sinda Display is a manufacturer of LCD for many years. Its headquarter is located in Shenzhen, Guangdong Province. Sinda has developed for many years, not only opening many factories in many provinces of China, but also has its own branches and factories in India. We have enough strength to support our industrial chain and meet the various needs of customers. As for after-sales service, our engineers and staff will solve all the problems about the products for customers.

The principle behind the LCDs is that for switching pixels on and off to reveal a specific color, LCD screens use liquid crystals. And, the molecule tends to untwist at the time of electrical current is applied to the liquid crystal molecule. This becomes the reason for a change in the angle of the top polarizing filter as well causes the angle of light, a light that is passing through the molecule of the polarized glass. Consequently, with the help of an individual area of the LCD, a small light is allowed to permit the polarized glass.

Thus, as compared to other areas, this particular area will become dark. Instead of emitting light, LCDs work on the principle of blocking light. A reflected mirror is arranged at the backside at the time of constructing the LCDs. An indium-tin-oxide is used to make the electrode plane, which is kept on top of the device. Also, on the bottom of the device, a polarized glass with a polarizing film is added. With the help of a common electrode, the LCD's complete area has to be enclosed, and the liquid crystal matter should be above it.

Then comes another polarizing film on top, and on the bottom, in the form of rectangle, the second piece of glass comes with an electrode. But make sure that both pieces are located on the right angles. The light passes through the front of the LCD when there is no current, reflecting with the help of a mirror and bounced back. A screen is in front of the light that is made up of pixels colored red, green, and blue. In order to reveal a certain color or keep that pixel black, the liquid crystals work for turning a filter on or off. This is the reason; the LCD monitors and TVs consume much less power as compared to CRT monitors or televisions.
