Polarizing filter to the 3. A positive or negative goes through transparent electrodes embedded in the substrate and turns on the 5. Light shining through the glass substrate strikes the LCD material and passes through to the 7. The positive or negative charge coming from the electrodes is received by the transparent anodes and passes through the 9. Outer glass substrate.
Light continues through a polarizing filter .
The two sets of polarizers move more or less perpendicularly to one another to let in less or more light. It takes more than 40 microseconds for the filters to respond to the LCD material. Because of backlighting, viewing the screen from an angle of more than about 40 degrees causes color and light shift. Inc. All rights reserved.
