The next generation of LCD displays could go toe-to-toe with OLED screens

- Nov 09, 2017 -

【R&D Department of Blaze Display】Panasonic announced last week that it has developed a new kind of IPS LCD display with a 1,000,000:1 contrast ratio, making it competitive with far more expensive OLED technologies. As HDGuru reports, the new technology offers a massive improvement over most of today's LCD displays, which tend to have an average of about a 1,800:1 contrast ratio.

Ever since plasma TVs met their untimely demise, the best picture quality has tended to come from OLED displays. While traditional backlit LCD panels tend to be cheaper and easier to make, they also feature a worse contrast ratio and less deep blacks when compared to OLED monitors, something that Panasonic’s new technology hopes to address.

The disparity in image quality between the two types of displays is caused by the fundamental technologies of OLED versus LCD. OLED displays work on a pixel-by-pixel basis, only lighting up where there is an image to display (and allowing for the deep, true blacks that the technology is known for), but LCDs use a backlight that illuminates all of the display cells at once. If you increase brightness of that backlight to get a brighter picture, you start to wash out the display, while lowering the backlight's intensity will get better blacks, but at the expense of crisp, bright colors.

Panasonic's new technology works by using light-modulating liquid crystal cells, which are able to control the light at each point on a pixel-by-pixel basis to reap the same benefits as OLED is able to offer. By controlling the amount of light allowed to pass through, the display can offer both bright whites and dark blacks on a OLED-competitive level, to the tune of a 1,000,000:1 contrast ratio (the ratio of the brightest white to the darkest dark — higher is better).
