LCD Display Enhancements by Jayco
Demanding and critical applications require information displays you can count on. Displays that don’t washout in sunlight, displays that remain clear through reflections, displays that can withstand heat, shock, vibration, and impacts. In short, you need displays that work no matter what.

Sunlight Readable
The chief requirement for sunlight readability is a well resolved image with high contrast ratio that doesn’t get washed out in high ambient lighting and direct sunlight.
Sunlight readability is the result of a combination of techniques that work together to ensure optimum readability in very bright conditions.
Chief among these are a high brightness display, the use of circular polarizers, a high contrast ratio, and the minimization of internal reflections.
LED Backlight
High brightness can be achieved through CCFL and LED techniques. CCFL is well known and low cost, but run hot, consume power, suffer from shock and vibration problems, lower light uniformity, short life, and high EMI noise.
LED backlights in contrast offer high uniformity, long life, low EMI noise and high shock and vibration resistance. They also have the advantage of low power consumption and low heat output, factors that significantly improve reliability.
Our LED backlights are all proprietary design using highly sorted, low variability multi-chip LEDs, and unique light guide design, for maximum light output, efficiency, and uniformity from edge to edge.
Another advantage of LEDs is that they are a green technology, being inherently more efficient, and also mercury and halogen free.
High Contrast Ratio
Contrast ratio numbers listed by all display suppliers (including ourselves) is that quoted by the source panel manufacturers for the LCD cell measured in a black room. The real contrast ratio seen by the user will be somewhat different, depending on ambient light conditions.
A number of factors affect contrast ratio. The ambient light is the most obvious, but it starts with the type of LCD cell technology. There is nothing we can do to improve on the CR of the display in a dark room, but we can significantly improve real world results by the use of different polarizers, light enhancement films and reducing internal reflections. All our displays are designed to offer higher contrast ratio in real world situations.
Lower Power Consumption
DC powered LED backlighting consumes less power than AC CCFL lighting. LEDs also eliminate the need for high voltage inverters and have much lower heat output. Power consumption is further lowered by using matched, low variability, multi chip LEDs, and our unique light guides that maximize light output and maintain high uniformity.
With today’s emphasis on green technologies and energy management, low power consumption is more important than ever.
Wide Dimming
LED backlighting controlled by our proprietary LED control boards enable wide dimming to ensure the optimum brightness for any light condition. Conventional displays have about a 5 step dimming control. We provide a 1000 step control all the way from full brightness to 0.1 nits.
Touch Screen
All our LCD displays can be specified with an integrated touch screen. While resistive and capacitive touch screens are the most popular and appropriate for most applications, we also offer SAW and IR touch as required. Controllers and drivers are provided with each touch screen for easy integration to your systems.
Wide Range DC Input
Many environments have variable quality power available so we have designed controllers that can accept from 6V ~ 30V input with no effect on the efficient operation or long life of the displays.
Fanless Design
Low power and low heat LED backlights together with industrial grade components enable fanless enclosures required for low noise, dust free and sealed requirements.
Optical Bonding
Optical bonding is a technology that enables us to dramatically improve contrast ratio and display legibility in all conditions.
A conventional display has an air-gap between the LCD cell and the cover glass; add a touch screen and there is another air gap. Every time there is an air-glass interface reflected light will reduce the visible contrast of the display. Optical bonding fills the air-gap to eliminate the air-glass interface and dramatically reduce the amount of reflected light.
Our optical bonding technology can increase real world contrast ratio by 5 ~ 10 times. Optical bonding when combined with anti-reflective, or anti-glare glass and/or touch screens are a very effective method of improving display legibility even without increasing the brightness of the display.
Moisture & Dust Free
Conventional LCD displays can collect dust and condensation in the viewing area and due to the air-gap between the LCD cell and the cover glass. Optical bonding will eliminate moisture and dust problems, which is why optical bonding is standard on our marine line of displays.
AR/GR Film/Glass
Through the use of optical bonding it is possible to use AR/AG film or glass to improve display legibility in all conditions. Anti glare surfaces scatter light so that you do not see sharply defined reflected images or direct light sources, but AG effects can reduce sunlight readability. AR treatments reduce reflections without scattering light and thus allow more light to pass through the substrate, greatly increasing readability.
Night Mode/Night Vision (NVIS)
The wide dimming capability afforded by our LED backlight and controller technology allows the use of our displays in light sensitive dark environments such as on ship bridges. We can also offer displays with NVIS capability.
We can also offer LCD displays with NVIS capability
Waterproof
Many of our LCD displays can be specified with waterproof or water resistant front bezels to IP65 standards. Certain designs can be made IP68 compliant suitable for full immersion underwater.
Rugged High Impact
Industrial grade materials, components and assembly techniques result in rugged displays suitable for most industrial environments. For harsher environments custom enclosures can be built.
To resist impact damage on the screen we can optically bond high strength glass such as chemically strengthened or tempered glass.
High Shock/Vibration
Conventional CCFL backlight displays and consumer displays suffer from shock and vibration problems that cause intermittent operation or complete failure. LED backlight and advanced mounting techniques give our displays considerably more shock and vibration resistance.
Wide Temprature Operation
Virtually all our LCD displays are designed for -20°C ~ +60°C operation with some capable of even higher temperatures. Extreme low temperature operation is available on request.
