Panasonic Liquid Crystal Display has announced it has developed a new model of its IPS liquid crystal panel that achieves a contrast ratio of over 1,000,000:1, which is 600 times that of conventional liquid crystal panels.
This high contrast ratio is achieved by integrating newly developed light-modulating cells that permit pixel-by-pixel control of backlight intensity. This achieves a faithful and high-grade video display, ranging from dazzling light to pitch-black.
The new IPS panel is suitable for use in professional-use High Dynamic Range (HDR) monitors for broadcasting stations and video production studios. HDR displays can reproduce images that are faithful to what people see, ranging from bright light to jet-black darkness.
Also, the new high-contrast panel is suitable for use such as medical monitors that require faithful video display and automotive monitors that require clear visibility without black floating[3].
Despite their track record in wide-ranging applications from B-to-C to B-to-B fields, conventional liquid crystal panels suffer black floating, white washout phenomenon, in dark parts of the display area when the backlight intensity is increased to raise brightness. When the backlight intensity is lowered to make dark parts clearer, these panels also suffer a loss in sparkle in bright parts. The new panel addresses these issues.
