Sunlight readable displays

Normal displays, especially TFTs, are difficult to read in direct sunlight. If you want to make them sunlight readable, you need to consider some points in the design of your TFT module.

1. The surface brightness must be at least 500 cd/m2, in fact it is better to provide e.g. 800 cd/m2.

You may notice that you will increase the brightness of your smartphone in direct sunlight. If you decrease the brightness, the TFT seems to be black. So an essential point in order to design sunlight readable applications is to increase the surface brightness with a powerful backlight.

2. Use an anti-glare surface or anti-reflection coating. 

With a special anti-glare lens or anti-reflection coating you can reduce reflections on the surface of the module, which make the TFT difficult to read in direct sunlight.

3. Use optical bonding of front-glass and touch to display

Additional boundary layers in the module, between frontglass and touch as well as touch to TFT, cause additional reflections. Eliminating those boundaries by bonding the parts with optical clear adhesive or optical clear resin, will increase sunlight readability.

Anti-reflection film

TFT modules with gasket bonding have an air gap between touch sensor and TFT. This gap leads to reflections in the TFT and is also the reason why TFTs look greyish, not black, in power off state.

The traditional solution to this problem is full-lamination, however this option is costly and not suitable for all types of cell and coverlens combinations.

An anti-reflection - moth eye - film can be a cost efficient alternative eliminating interfering reflections.

In off state, the module looks more blackish, which gives the application a fine look.

Most TFT-modules can be equipped with moth eye film, contact us for inquiries!
