Backlight Updated: 12/20/2017 by Computer Hope LCD screens are unable to illuminate themselves, so they require a backlight to provide the illumination, thus creating a viewable picture on the screen. Backlights can provide illumination from the back or the side of the screen, which are different from front lights that illuminate from the front.
It's a staple food in some areas of the world. People on gluten-free diets often enjoy bread made with tapioca flour. In addition to tapioca pudding and bubble tea, tapioca is often used as a thickening agent when cooking, especially in soups. Because tapioca does not have a strong taste of its own, it can be added to many dishes to thicken them without changing the taste too much.
Tapioca flour can also be used as a thickener in sauces and gravy, but it is not my favorite thickener to use because I have found that it tends to make the sauce a bit slimy. I know a few gluten free people that do not like the flavor of tapioca flour in their gluten free cooking and they often substitute cornstarch.
