What Components Make Screens Sunlight Readable?
Reading data in direct sunlight from the screen of a mobile device is not always easy on bright days. While working in an indoor workplace, you can move your screen and adjust it to block direct sunlight, while working outdoors this isn’t always possible. It is therefore, essential that mobile industrial devices such as tablets and smartphones have high quality displays that are easy to read while in a range of different situations.
Brightness
To achieve the required brightness a strong backlight is often necessary and to improve the user experience on the move, a light sensor that automatically adjusts the screen brightness is also commonly included.
A bright screen is one of the most fundamental aspects of a sunlight readable screen. With high screen brightness, even in direct sunlight, it is possible to read the screen and to recognise a range of different colours.
Contrast
The contrast of a display plays an important role. It is the ratio of the brightest white to the darkest black which defines how strong the contrast off a screen is. With higher levels of contrast, it is easier to recognise a range of different images and read text on the screen. The display of an industrial device has a screen which is approximately 6 times higher contrast than a corresponding consumer product, further adding to the usability of the device while working outdoors.
Reflection
One challenge when using a screen outdoors is that screens can reflect the sunlight which can make a screen unreadable due to the glare of the sun. This can distort the colour of the screen and in worst-case situations, make the whole screen unreadable. A screen which has a low amount of reflection is essential when using a device outdoors on a consistent basis.
In order to rely on a device while using it outdoors, it is important that all of the above factors are considered. Ensuring a device can be used in a range of conditions is something that has been carefully considered when designing ecom’s latest range of tablets and smartphones, ensuring that they can be used at all times and in all environments, regardless of the weather.
