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.
Commercially prepared tapioca has many uses. Tapioca powder is commonly used as a thickener for soups and other liquid foods. It is also used as a binder in pharmaceutical tablets and natural paints. The flour is used to make tender breads, cakes, biscuits, cookies, and other delicacies (see also Maida flour).
