Two colours in a single device for cost-effective indication in displays
13 April 2023
New from OMC are Dual Status Profiled Backlights, which combine two colours of emitter in a single profiled backlight, enabling designers to use the single backlight source to indicate status very clearly, rather than a single colour backlight that is simply on or off.
The Dual Status Profiled Backlights are easy to integrate and drive, suitable for industrial, petrochemical, instrumentation and medical designs, and providing clean, clear and bright backlight colour which can be seen from oblique angles.
Bright and clear display illumination ensures that a machine-human interface is easy to understand.
As robust components with an extended product life, Dual Status Profiled Backlights can be used in multiple applications and industries, including harsh environment applications such as the petrochemical industry (explosive gas detector systems, display systems for oil pipeline valves, gas and electricity metering), and in research, instrumentation and medical applications (life support system displays, imaging applications, measurement instrument displays).
Dual Status Profile Backlights bring benefits to industrial applications where colour backlights have not previously been a practical solution for displays, as they solve the additional cost and reliability issues around adding multiple LEDs to a backlight cost-effectively, when custom dimensions are required. Dual Status Profiled Backlights take up less space in a design and provide a cost-effective solution, even for small- to medium-volume requirements. The two colours indicate status very clearly and provide a way to attract attention even from an oblique angle. Temperature status is a common application, where the use of a red LED emitter alongside a green LED emitter, enables a fast “switch to red” warning.
Dual Status Profiled Backlights have individually addressable LED emitters, and available colours range through ultrabright blue, four greens, three yellows, orange, three reds and ultrabright white.
OMC Commercial Director, William Heath, comments, “We pioneered the introduction of LEDs as a backlighting technology over thirty years ago with our Profiled Backlight range, and invented our side-firing backlight emitter, which illuminates backlights in a wide range of colours and brightness levels. Our new Dual Status Profiled Backlights are a further development of our award-winning technology and our unique manufacturing techniques mean any quantity can be produced cost-effectively, from less than ten parts to tens of thousands, with samples available in as little as five to ten working days.”
