In the medical field, displays are required to have accurate image quality with, high-brightness, and high-contrast for the best image diagnosis. JDI has developed a 21.3-inch high resolution (5mega-pixel) monochrome TFT display incorporating our new Dual-cell technology to meet the needs for higher performance displays required by the medical market demands.
JDI devised the LCD structure to control dimming of the panel to solve double images and missing images due to viewing angles and a halo effects caused by the combination of a reducing parallax and an optimization of the dimming area. The result greatly improves the display quality that can then be applied as a medical diagnostic solution.

To achieve such high-definition image quality and high brightness, JDI utilizes LTPS technology for wide viewing angles and high contrast by means of IPS liquid crystal.

Sample shipment of this product will start in May.
