Can PenTile RGBW be used for TV?

You bet!

Samsung SEC has built prototypes of a 32-inch FHD TV using PenTile RGBW with a white LED backlight.  This was demonstrated at the 2010 Flat Panel Display International (FPDI) conference in Makuhari, Japan.  This PenTile RGBW LCD  TV runs at about 55% the power of an equivalent brightness legacy RGB stripe panel showing the full range of multimedia applications.  The PenTile RGBW TV is capable of even higher savings for TV or video alone.

Due to the white subpixels, the white areas and reflections from things like the metal in a chrome bumper have a real zing that is not seen in conventional RGB stripe TVs.

Just like the mobile displays these are built with one-third fewer subpixels, but from only 2 meters away the pixels are seen as 48 cy/deg* of human vision where the pattern is not easily seen by the best of eyes.

* 48 cy/deg means that in one degree of human vision one can see 24 white lines and 24 black lines
