Describe how a led screen works
WebLCD displays work by using individual pixels to display visuals, moving or stationary. Each pixel will display a color mixed by the RGB color filter with each color’s filter associated with one of the pixel’s sub-pixels. WebLED screens work in a similar way to LCD screens but with one major difference, the light source. Small LED bulbs are used to provide light to the LCD pixels, not fluorescent tubes. These LED bulbs either fill the entire back of the display unit, or on thinner models are just arranged around the edges.
