Application Spotlight, May 2019

Human-Machine Interface (HMI) is a critical aspect of product design that comes in the form of keypads, membranes, phone applications, or touch panels. Today, many industrial, medical, HVAC and other markets utilize touch panels as the main form of HMI.

With so many environmental factors considered in product design, choosing the right technology is important to ensure a ruggedized solution that will outperform the environment that the product is exposed to.

In addition to off-the-shelf touch panel solutions for most sizes under 10.1″, AZ Displays specializes in customization of resistive and capacitive touch panels. With integration facilities in both southern California and China, AZ Displays can support a wide array of applications and display sizes (up to 65″ with consigned product). The following are amongst the most commonly designed value-added services for touch panels:

Beyond optical enhancement, these value-added services help in counteracting environmental obstacles in applications that are exposed to harsh environments:

Application Spotlight, March 2019.

The continued evolution of the electronics industry has forced many hardware developers to adopt modular platform approaches in order to launch product into the market as swiftly and efficiently as possible. Today’s easily accessible world-wide market challenges companies to differentiate with features tailored to the audience or end customer.

AZ Displays has itself taken this approach with development of their turnkey LCD solutions, resulting in highly customizable display sub-systems ideally suited to developers of industrial, medical, pool/spa, HVAC, and irrigation systems. Our engineering team excels at taking our standard
product line (1.77″ – 10.4″) and integrating value-added features/services that include:

By offering as many layers of the Human-Machine-Interface (HMI) possible, AZ Displays offers a solution for engineers to reduce the amount of design time required to integrate a Touch LCD solution into their product, and limits the number of vendors on a BOM. This reduces qualification time, improves tolerance stack up within the HMI components, and reduces software/firmware initialization design time. By saving engineers time and money, AZ Displays helps to keep their customers ahead of the curve and get product out into the market as efficiently as possible.

The subsequent parts of this application spotlight series will feature :
Part 2/3: Visual Value-Add (Optical Bonding, Silk Printing, Custom Cover glass)
Part 3/3: Performance Value-Add (HDMI Boards, USB Touch Controllers, Sealing/Gaskets).

Readability of LCD displays in outdoor human-machine interaction is becoming an increasingly critical factor in a variety of applications.

Traditional Mono LCD modules often run into the obstacle of poor readability in an outdoor ambiance due to brightness and viewing angle restrictions. Designers must then consider TFT LCD technology to overcome these obstacles, but with the trade-off of more expensive data logic controllers and the additional time/effort required to redesign the application.

Application: Environmental Monitoring Instruments
AZ Displays has recently been approached by a leading manufacturer of environmental monitoring instruments (air quality/ pollution monitoring) looking for improvement opportunities related to poor readability performance of mono LCDs in some of their outdoor products.

AZ Displays has developed a High Contrast Graphic Module with TFT LCD logic (3.5” and 5”), while utilizing a monochromatic LCD graphics driver. Integrated with ZETTLER’s patented driver logic technology, this HC Module can offer an easy connection and plug-in replacement for customers’ existing Mono LCD Module design while providing a much higher contrast, better viewing angles and more display color options compared to traditional Mono LCD products.

AZ Displays introduced the customer to the High Contrast Graphic Module (ATM2412 series) which is a perfectly fitted solution for their requirement. Adopting this plug-in-ready replacement option with a simple calibration adjustment, allowed the customer to quickly convert to a High Contrast Graphic solution, ideally suited for the customer’s outdoor portable product application
