TOKYO (ICIS news)--Japanese chemical producer Toray Industries has developed a resin for liquid crystal displays (LCDs) which is highly effective in blocking light rays, the company said in a statement on Thursday.

The new material, which is coated with a layer of polyimide, would improve the display properties of LCDs such as the contrast when it’s used as the black matrix in the colour filters of LCDs, the company said.

Black matrix (BM) is a pattern formed on colour filters to shield the backlight and improve the display contrasts by preventing red, green and blue (RGB) pixels from getting mixed, it added.

Toray had become the world’s first company to successfully mass produce resin BM for color filters of LCDs, the company said.

It had in 2002 stopped using the traditional metal chrome BM and started producing color filters with the more environmentally friendly resin BM, it added.

Toray aimed to increase the sales of colour filters to industries requiring high-resolution displays such as those used in car dashboards, the market of which was expected to expand, in addition to applications for TVs and mobile phones, the company said.
