Industrial grade display solutions offer an extensive variety of interface options for both display and touch communications. Today, the two standard options for TFT technology, both traditional TN and the higher performance IPS, are RGB and LVDS. For PCAP touch solutions, I2C is the main off-the-shelf protocol. Many design engineers today are turning to solutions that require the least amount of software and hardware development and prefer to utilize development tools such as SBC/SOM that come HDMI and USB-HID ready for touch.
In addition to off-the-shelf LCD and touch solutions, AZ Displays offers “backpack boards” that allow users to communicate to our TFT/IPS LCDs by means of HDMI or VGA. These A/D video boards can be initialized to work with multiple display sizes, resolutions, and backlight driving characteristics. Ideal for SBC/SOM mainboards with HDMI/VGA input, these low-profile boards can be tape attached to the back of LCDs, or can be mounted by hardware (through-hole stand-offs) to accommodate most product designs. Our touch panel controller boards make both resistive and PCAP touch panels USB-HID ready, for a true plug and play solution. These backpack boards come as standard solutions or can be customized to be application/design specific. Below is a list of solutions that AZ Displays has provided to the industrial display market:

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:
Custom Cover glass (up to 9H Hardness)
Extended Cover glass
LED Logo Integration
Beyond optical enhancement, these value-added services help in counteracting environmental obstacles in applications that are exposed to harsh environments:
Suitable for outdoor applications, ideal for reducing refraction of light between the LCD and touch panel by eliminating air gap.
Eliminates the possibility of condensation and humidity penetration between the LCD and touch panel.
Custom Cover Glass
Enhance strength for impact resistance, ideal for outdoor applications such as kiosks.
Specialized glass chemistry to address medical application requirements to have non-shard glass.
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:
Custom Cover glass (up to 9H Hardness)
HDMI A/D Boards & USB-HID Ready Touch Controllers
Discrete Cap Touch
Consigned Material Assembly (Enclosures)
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
