Japan Display Inc. (JDI) has developed a 32-inch reflective-type color LCD module for outdoor digital signage systems, leveraging JDI's MIP technology already in mass production for small-sized reflective type color LCD module for wearable devices. The module will be privately exhibited nearby the Las Vegas Convention Center for three-day period June 8 - June 10, during InfoComm2016, held in Las Vegas, NV, USA.
JDI will start shipping samples of the new display in July.
The display features a Memory-In-Pixel (MIP) structure, which holds screen images in SRAM fabricated in each sub-pixel, realizing ultra-low power consumption - approximately 1/500th of that of high-brightness transmissive-type LCD modules designed for outdoor digital signage systems.
The low power consumption of the display means that it could run on battery power, and when combined with solar cells, the system can be used almost anywhere without an electrical AC power source.
The syetam also features an optimized scattering layer in order to display bright and crisp images even in direct sunlight.
Its backlight-less structure allows the design of lightweight and compact digital signage systems, compared to conventional high-brightness transmissive-type backlit LCD modules. In addition, digital signage systems based on the new module require no cooling system and thus are more durable and reliable than high-brightness LCD modules base don heat-generating backlight.
The module has 1.3mm narrow borders on three sides, enabling near-seamless tiling, in ultra-large-size digital signage applications.
