How LCD Displays Work: Positive Mode – Letting the Light Shine
Positive mode is the more commonly used of the two ways in which LCD displays work. In positive mode, dark letters, numbers, and symbols appear on a light background. The diagram and photo below show an example of a positive mode static display.
Positive mode LCDs are popular because they don’t require a backlight to function, and therefore use less power. Typical applications of positive mode LCDs include wrist watches, hand-held calculators and battery-operated temperature gauges.

An LCD TV is sometimes referred to as a "transmissive" display — light isn't created by the liquid crystals themselves; a light source (bulb) behind the panel shines light through the display. A white diffusion panel behind the LCD redirects and scatters the light evenly to ensure a uniform image.
The display consists of two polarizing transparent panels and a liquid crystal solution sandwiched in between. The screen's front layer of glass is etched on the inside surface in a grid pattern to form a template for the layer of liquid crystals. Liquid crystals are rod-shaped molecules that bend light in response to an electric current — the crystals align so that light cannot pass through them. Each crystal acts like a shutter, either allowing light to pass through or blocking the light. The pattern of transparent and dark crystals forms the image. It's the same display technology behind your digital watch but way more sophisticated.
