led tv white spots image
Trinfinity
I understand that there millions of little pixels in a high resolution tv/monitor but what causes them to light up/change colors? How do we control the colors and such with digital code?
Answer
LED televisions are simply LCD televisions that use LEDs for backlighting instead of the usual cold cathode fluorescents.
LCD TVs produce a black and colored image by selectively filtering a white light. The light is provided by a series of light emitting diodes (LEDs) at the back of the screen. Millions of individual LCD shutters, arranged in a grid, open and close to allow a metered amount of the white light through. Each shutter is paired with a colored filter to remove all but the red, green or blue (RGB) portion of the light from the original white source. Each shutterâfilter pair forms a single sub-pixel. The sub-pixels are so small that when the display is viewed from even a short distance, the individual colors blend together to produce a single spot of color, a pixel. The shade of color is controlled by changing the relative intensity of the light passing through the sub-pixels.

Why does my new xbox 360 kinect only play in black and white on my sharp aquos LED tv? Im using the RCA cord?
Christophe
in reference to earlier answered questions. There are no other cable bundles. just power, kinect, and the red, white, and yellow rca cable. tv only has one choice for the video cable.
Answer
you might have it hooked up wrong check the cord carefully to see if they aare in the correct spot in so try an hdmi or another xbox video cord.
