Based on a telescope design invented by Isaac Newton, US technicians have developed TV displays which would consume less electricity comparatively. Anna Pyayt of the University of Washington, Seattle elucidated that one could build a brighter monitor for the same amount of energy or use less energy to get the same brightness.

 

Factually, the rear layer of a conventional LCD (liquid crystal display) used in televisions produces light (backlight). And, the brightness is controlled by small liquid crystals that swing round like tiny shutters; however a good chunk of this backlight is wasted and never reaches the viewer. The researchers want to utilize the same light to save electricity.

 

Now, the new research shows that swapping the liquid crystals with microscopic mechanical mirrors arranged in a way Isaac Newton arranged in his telescope design could efficiently use the backlight. Further, the displays using these telescopic pixels are more power efficient and easier to read in direct sunlight than conventional displays.
