7 Steps to improved sunlight readability for your LCD display:
1. Take your time to select the proper display for your application. Selecting the wrong display in the beginning of your project can lead to disasters further down the road. If you would like assistance in this area, contact one of our display specialists to get started in the right direction.
2. Use anti-reflective or anti-glare coatings on all surface areas, whenever possible. These will help bring to contrast ratio closer to it's original "dark-room" reading.
3. When applying a touchscreen, or other device in front of your LCD display, select the display with the highest transmissivity ratio among those that are durable enough to stand up to the application you product is designed for. Many manufacturers make resistive touchscreens with transmissivities as high as 92-95%, including: Fujitsu, Gunze, and others.
4. Work with a professional company, such as FPD Group, to do "behind-the-glass" enhancements -such as improved light guides, improved optical filters, etc. These enhancements often provide up to 40% increased transmissive brightness (and, in some rare cases, can even double the transmissivity of a display).
5. Make sure polarization of any devices in front of your LCD (such as a touch screen or various filters) are compatible with that of your LCD. Place the device in front of your LCD in direct sunlight and turn the device that lies in front. If the device yields a picture that is more sunlight readable when it is skewed from the way it is supposed to be placed to begin with, then you may need to switch touchscreens or ask your touchscreen manufacturer to adjust their touchscreen to be compatible with your display. Because of this, higher transmissivity touchscreens may not show as well in direct sunlight as those that are less transmissive, but are more properly aligned.
6. Have your display enhanced to be transflective, by FPD or other reputable companies -this process often integrates some of the steps mentioned earlier for best results.
7. If all else fails, look into "active enhancements" such as backlight replacement or (be very careful here) overdriving the backlights. For the best display, you may even want to use anti-reflective or anti-glare filters in conjunction with actively enhanced displays.
If that doesn't work, or if you'd like some help with any of the processes mentioned above, contact one of our display specialists here at FPD Group...
