Televisions that use a combination of an LED backlight with an LCD panel are sometimes advertised as LED TVs, although they are not truly LED displays. [1] [2] Backlit LCDs cannot achieve true blacks for pixels, unlike OLED and microLED displays. This is because even in the "off" state, black pixels still allow some light from the backlight ...
Generic names include black frame insertion and scanning backlight. Philips created Aptura, also known as ClearLCD, to strobe the backlight in order to reduce the sample time and thus the retinal blurring due to sample-and-hold. [7] [8] Samsung uses strobed backlighting as part of their "Clear Motion Rate" technology. [9]
LCDs filter the light emitted from a backlight, allowing a small fraction of light through. So, they cannot show true black. However, an inactive OLED element does not produce light or consume power, thus allowing true blacks. [32] Dismissing the backlight also makes OLEDs lighter because some substrates are not needed.

Response time
Black levels may not be as dark as required because individual liquid crystals cannot completely block all of the backlight from passing through. Display motion blur on moving objects caused by slow response times (>8 ms) and eye-tracking on a sample-and-hold display, unless a strobing backlight is used.
A backlight is a form of illumination used in liquid-crystal displays (LCDs) that provides illumination from the back or side of a display panel. LCDs do not produce light by themselves, so they need illumination (ambient light or a special light source) to produce a visible image.
Element Electronics offers a wide range of televisions integrated with Xumo, Google TV, and Roku TV smart streaming platforms. Their televisions range in size from 19” to 86”. [ 11 ] They also offer monitors, sound bars, and major appliances: refrigerators, freezers, washers, dryers, dishwashers, ranges, microwaves, and air conditioners.
The violet glow of a blacklight is not the UV light itself, but visible light that escapes being filtered out by the filter material in the glass envelope. A blacklight , also called a UV-A light , Wood's lamp , or ultraviolet light , is a lamp that emits long-wave ( UV-A ) ultraviolet light and very little visible light .
