LCD 2.0 combines a reflective LCD (RLCD) with the Azumo Front Light Panel and Azumo Lightguide Film, offering the first complete power-efficient solution for maintaining consistent display contrast across dynamic lighting conditions.
In a backlight display, light is beamed from behind the display, while a front light transmits light from an LED array at the edge of the device to a central area through light guides – reducing strain on both a consumer’s eyes and the device’s battery.
For many devices, operational issues occur when air gaps between a cover lens and a display form, leading to problems with data entry and leaving room for water ingress and moisture collection. But with new cover lens bonding technologies, designers can increase product reliability without sacrificing display features and readability. Displays can be bonded securely to protective elements like Gorilla Glass, offering the best possible protection and longevity for the product.
Azumo front light technology comes in a variety of display size options and is well suited for a variety of applications including defense, medical, educational, industrial, consumer, and automotive devices.
Historically, contrast ratio has been used to measure how bright the light is compared to the blackest of the black on the display. When you see contrast ratio on a display spec sheet, it typically is going to be measured in a dark room. This is fine for televisions that are used indoors or a dark environment like a movie theater. However, the reality is that we have devices being used everywhere, our handheld devices are being taken outdoors in the bright sun and into much harsher conditions than previously possible. Contrast ratio doesn’t capture what really happens when devices are in a real use experience.
Ambient contrast ratio is a newer specification that people are starting to use for applications with displays. It is extremely important as it is dependent on where people are using their devices.
- Low power: one LED, efficient coupling
- Ultra thin: (50um) less thickness to your design
- Clear: invisible, distortion free
- Uniform: evenly diffused light source
- Flexible: edgeless, fits curved panels
- Elegant: laminated streamlined module
Yes! Azumo’s LCD 2.0 display modules are compatible with standard LCD drivers, making it easy for engineers to design one of our modules into any device that would use a traditional LCD.
From a performance standpoint, there is no difference between these configurations. The difference is strictly mechanical in order to offer multiple options to choose from when integrating LCD 2.0 into your design.
Yes, you can build intrinsically safe devices with Azumo.
We have seen customers mount the displays in multiple ways. One recommended design is installing the display in a gasket using PSA and pressure to keep it in place.
We’ve also seen customers using a carrier piece to key off the exposed glass edges and then bond the flat part of the display with a double-sided adhesive so he LCD is fixed onto the carrier. The carrier then is assembled into the device.
Using Sharp as an example, the Sharp Memory LCD has a storage temperature of -30C. At that level, however, the liquid crystal material freezes to a solid state and it may not recover once returned to normal temperature. We’ve seen the Sharp displays run at -40C to +80C. The response time at the low temperatures does slow down significantly but no permanent damage has been reported. On the Azumo side, we test to those specs for the front light panel. We have selected materials that match LCD environmental specifications.
