Polishing of pre-layered substrates.Pursuing further thickness reduction in LCD display.

Liquid crystal displays for cellular phones, laptop computers, digital cameras, and a variety of other products. Our micron-level advanced manufacturing technology is utilized in every day life.

An LCD display is made of two thin sheets of glass.

Liquid crystal display, so-called "LCD," is made of two thin mother glass substrates "sandwiching" liquid crystals in between. This "space" between each glass substrate is only several microns. The complete LCD is less than 0.5mm thick.

With the rapid growth of "thinner" and "lighter" mobile electronics, cellular phone, laptop computer, digital camera, etc., there is more demand now for the two sheets of glass to be much thinner. Using conventional methods, we previously polished each glass sheet piece by piece, then in a separate process, joined the panel layers together to form one LCD display. However, this method generates issues with glass breakage when being manufactured into a liquid crystal display.

Here's how to do it! Nitto's high-precision technology

Polish the entire LCD display sandwich

Avoid the risk of breakage, yet still achieve thinner glass parts...

To provide thinner and lighter LCD displays with much higher precision flatness, Nitto employs a technique to polish the display while being sandwiched between two glass substrates. Conventionally, it has been more common to separately polish these mother glass substrates before placing the liquid crystal layer in between. However, to achieve "thinner and lighter" while maintaining high precision, we developed a new technology to polish the entire finished display at a time. We were among the first to develop this technology in the worldwide industry and successfully integrated this polishing technique into our production line.

LCD display sags because of its own weight.
