OLEDs (Organic LEDs) are one of the latest developments entering the optoelectronics arena. The ability to use organic compounds in LED usage is the wave of the future and as always, VCC is following the development of this field. Below we are going to cover some of the main questions concerning OLEDs including their composition, operation, usage, benefits and disadvantages.

What are OLEDs?

OLEDs are Organic Light Emitting Diodes. Kodak was the first to develop this Technology that uses organic compounds such as glass and plastic to compose the emissive electroluminescent layer. This layer is no thicker than a film and is applied in a process that is simple, low cost and requires fewer materials than other LED compounds used to emit light and provide full spectrum color displays.

What types of OLEDs are there?

There are three basic types of OLEDs being developed and implemented. Those types are:

• Small Molecule OLED – Known as SM-OLEDs, these devices are typically made from glass substrates and are deposited through a vacuum process. The SM OLED is more efficient than the other types and can be evaporated allowing for complex multi-layer structures. The drawbacks with the small molecule OLED is that it is not flexible and the vacuum process is more expensive than other OLED types. Newer developments with stacked and flexible plastic substrates are removing the disadvantages and this product is expected to have large impacts in the future of OLED installations.
• Polymer OLED – Also called Light Emitting Polymers (LEP), this OLED type is generally composed of a plastic compound that forms the electroluminescent conductive layer. The process for depositing the materials in this layer is a precision ink jet application. This process is low cost, simple and can be created with multiple levels to improve efficiency. Once applied, it is extremely flexible. The drawback with the Polymer OLED is that current efficiency is not at the level of the SM OLED, however, it has surpassed LCD efficiency levels.
• Phosphorescent OLEDs – This OLED type has up to four times higher efficiency than that of a conventional fluorescent OLED. Its application process is the same as the Polymer OLEDs as it is applied by precision ink jet printing, however, it is highly efficient in converting electrical energy. Recent developments are assuring the future success of this OLED type.

The Future of OLEDs

Many different versions of these main OLED types are entering the market. They offer a full color spectrum that is thin and flexible. Future displays using OLEDs will be flexible, low cost, brighter and more efficient. OLEDs also have a wide viewing angle with high contrast video capabilities. This technology is expected to result in displays less than 1mm thick.

Lighting indication presents some of the larger challenges in today’s production environments. Accurate monitoring of varied processes are key in developing an efficient and successful process environment. A combination of lighting indicators and user interfaces provide important and immediate feedback to the operator’s and others in process control field. This feedback can either be effective and improve production or if implemented incorrectly can confuse and create additional issues which are detrimental to quality control.

The most important challenges to conquer in lighting indication are the following:

• Visibility – Though it seems simple and obvious, the most important consideration in lighting indication design is visibility. Using the right type of indicators for your environment and installing the lighting where it can be easily viewed and analyzed by operators and maintenance personnel is essential.
  • Stack and Tower Lights – Standard machine condition such as ‘power on’ (green), ‘maintenance needed’ (blue), ‘caution’ (yellow) and ‘stop/alarm’ (red) are some of the varied indicators most commonly used with stack and tower lights. Implementation of these devices allows clear communication of machine status to any personnel entering the production environment. The ability to quickly analyze the machine conditions can minimize or even eliminate downtime.
  • Panel Indicators – Process data, environmental conditions, switch indicators, sensor status and a number of other messages displayed on the operator panel can streamline system processes. Where paper manuals and signs can be misplaced or damaged  and thus not available when needed, a row of panel indicators or several rows can be easily mastered by the operator through repetition creating a more efficient employee and process.
• Process Communication
  • Varied indicator types and signaling – Using a row or row of indicators on your panel of various shapes, sizes and colors is an effective way of communicating process status, alarms and accomplishing accurate control monitoring. Implementing lighting indicators as sensor emulators showing a variety of conditions is possibly the most effective way to increase efficiency and gain more process control.
  • Operator Training – The key to achieving a more streamlined process through implementation of lighting indicators is operator training. Using various indictor types and signaling such as flashes or a series of lights to indicate a certain condition is only as effective as the understanding of the operator. Initial training and quick notification of process changes is mandatory if production is to be increased.
  • Consistency across process types – Consistency of your lighting indicators will eliminate confusion and increase effectiveness by allowing one operator to easily move between production steps and still maintain an accurate understanding of the lighting communication. It is not often possible to have all lighting indicators communicate the same message but providing consistency across each process type should be taken into consideration. Creating an environment that permits cross training in a minimum amount of time and with a minimum amount of change in the meaning of the machine indicators allows flexibility and highly productive employees.

VCC offers a wide variety of lighting indicators for all your environmental and process needs. Check out our catalog or contact our dedicated professionals to assist you in streamlining your lighting indication process and creating the most efficient production environment possible.

Automated production processes are implemented in almost every factory environment operating today. Good LED indication practices should alert, inform and guide the operator. With the ever-growing number of automated processes and machines, keeping consistent signaling can become quite a challenge but must be implemented for the following reasons:

• The first generation of automation workers is retiring and work forces are shrinking. Those leaving the workforce are taking with them important knowledge of machine operation and in their place is a less experienced team.
• With the reduced process knowledge, having as much consistency in your signaling as possible will help lower the learning curve and result in better performance with predictable volumes of quality product.
• Lost and misplaced hard copy documentation during a crisis can result in increased downtime as the operator may be unaware there is a problem or unsure how to resolve it. With consistent signaling the operator will come to recognize warning signs that can be addressed before the process is halted.
• Standard signaling for common alarms allows the operator to quickly deduce the cause of a machine failure and either fixes the failure or calls maintenance with a clearer diagnosis of the problem.

When engineering your production floor layout, taking into account the basic signals that can be grouped and displayed in a consistent manner is essential for optimizing efficiency and quality. For alarm signaling the recently released ISA/ANSI 18.02 Alarm Management for the Process Industries provides excellent guidelines for indicating and prioritizing alarms. Having indicators on machinery or in stack lights for warnings or caution conditions should be standard as well. Addressing an upcoming error will be simpler and less expensive than the downtime once failure is realized. Implementing standards for your automated indicators and processes will improve your production floor in the following ways:

• Operators will learn your system quicker and be better able to respond when unexpected actions occur.
• There will be a greater tuning of your processes that will allow more consistent forecasting of product.
• You will achieve better diagnostic and more reliable data from your workers as they will better understand the systems.

LED’s are a staple of signage and signal applications and with the wider use of high power LEDs the range of applications is constantly expanding to practically limitless proportions. High power LEDs can be driven at currents from hundreds of mA to more than an ampere, compared with the tens of mA for other LEDs. Until recent years their use has been limited by the need for large heat sinks and thermal management issues.  The latest developments have introduced the ability to control and maintain brightness levels without “hot spots” and “not spots” for further efficiency improvements. More strategic configurations of heat sinks, new heat sink materials and metal core printed circuit boards have improved control thermal of management problems. These advances have allowed new areas of development.

High power LEDs from VCC are now in use for in an almost limitless number of applications among which are:

• Accent lighting applications such as: contour lighting, stairway lighting, pendants, coves, displays and front panels.

Large panel LED displays are becoming the only way to go if you are looking into signage. From stadium signs to retail marketing and even traffic signs, LED displays are being implemented into designs in an ever-widening array of applications. Panels and displays are also becoming larger and with these larger panels are power, brightness and management issues. There are two main configuration options being employed, each with its own pros and cons.

When the LED’s are placed directly behind the panel, they are in direct configuration. The other option used widely is edge configuration where the LED backlighting is provided by LED’s installed around the perimeter of the panel. Either design option will give you the capability of color variations, consistent movement and the bonus of virtually eliminating outages.

The direct configuration utilizes LEDs arranged in a matrix behind the panel to directly illuminate the display. This configuration uses less current through many small strings of LEDs, which allows for local dimming of individual arrays in addition to improved coloration and contrast. Drawbacks of this configuration are that you need to use a high-speed data bus and your programming will be much more complex. This configuration also requires thicker panels to allow space for the light emanating from the LED’s to diffuse.

Edge configuration illuminates the display from the panel edges using fewer strings with more LEDs.  This requires a higher voltage power supply to drive the LEDs, however, there is a less complex control system required and fewer LED current sink drivers. Being arranged in longer strings around the perimeter also allows for a much thinner display. Newer systems use a phase delay evenly across the strings to aid in reducing the peak inductor current inherent to the use of a higher voltage power supply. This configuration is becoming the standard when retrofitting large screen LCD displays.

Whether you are looking for small or large panel displays the boundaries between LED lighting and displays are blurring into one world where the highest quality and quantity of content is provided by one device type. The experts at VCC are prepared to help you plan for the requirements of your display type, placement, thermal management and power.

In today’s production atmosphere, cost, time and efficiency while implementing quality processes determine the bottom-line success and profitability of your product. A tried and true way to accomplish a piece of this goal is to use quality pre-engineered and wired cables.

Among the many benefits are:

1. Design Flexibility – Using pre-wired cables in your project from the design stage on, allows the Engineer greater flexibility in a number of aspects. Panel space is always at a premium and a great way to conserve space is to install pre-wired cables. It reduces the need for wire trays and permits greater variety in the placement of PCB’s and other components as cable routing becomes less inhibited.
2. Reduced Wiring Time and Costs – The amount of time needed to wire your cabinet or machine is reduced as connecting cables is a much quicker process than routing the cables, making a connections and labeling each wire and termination point. The number of wiring errors will also diminish, as fewer opportunities for a wiring mistake are present.
3. Easier Marking and Labeling – Pre-wired cables will arrive labeled and with diagrams declaring each connection point. The assembler is then left with verifying the points of connection and labeling the cabinet for clear and correct assembly.
4. Faster Testing and Replacement Times – The testing of cabinets with pre-wired cable assemblies is a more efficient process than cabinets with individual connections. The tester can easily check for continuity and signal presence without disconnecting the cable. If repair is needed or a function added or changed, a pre-wired cable is much more flexible. Your service provider can show up with a new cable and complete replacement in a matter or minutes resulting in less downtime for the client and a shorter visit for the provider.
5. Fewer Parts, Less Inventory – Use the space that used to store multiple cable components to increase production area as pre-wired cables can take less than half the space. Reduced inventory and increased space will raise your profit levels.
6. Quality Panels – Let your company be known by the caliber of your panels. Pre-wired cabling means your applications will be neater and safer than individually routing each termination point.

Contact the committed team of experts at VCC today to discuss your individual pre-wired cable needs. We specialize in collaborating with our clients to improve all aspects of production and provide you with dynamic, quality solutions. We can Engineer the cables for your application or use your data to provide a flexible pre-wired cable customized for your project requirements.
