Japan Display has developed a 21.3-inch high resolution (5 mega-pixel) monochrome TFT display made by low temperature polysilicon (LTPS) technology.

When a-Si technology is used in high-end medical monitors featuring high brightness (e.g., 2000cd/m2), there are certain side effects that arise from using a more powerful backlight, such as higher cost, bulky heat-sink design, potential noise from fans, higher power consumption, etc. Japan Display claims that these medical monitors need a better display solution to overcome these problems. By using LTPS technologies, the new display has higher tranmissivity, which contributes to a one-third (1/3rd) power consumption savings compared to the conventional a-Si product. Furthermore, LTPS technologies enable the new display to have fewer driver-ICs and a finer driving circuit layout. Thus, the display's border can be narrowed by nearly 45%, which helps doctors to easier read and interpret multi-frame radiology and mammography images.

Japan Display will start sampling this new product in the fourth quarter of 2017, and mass production planned to start in the second quarter of 2018.
