LED-backlit LCD television is a liquid crystal display television that uses light-emitting diodes (LEDs) as backlight sources. Some TV manufacturers, such as Samsung, Panasonic, Toshiba, Philips, LG, and Sony, call it LED TV (LED TV), but this does not refer to TVs that use light-emitting diodes as image display.
A Micro LED pixel is made up of red, green, and blue subpixels. Micro LEDs can be brightened or dimmed individually or in groups and can be turned on or off rapidly. Micro LEDs closely match the performance of the OLED technology used in select TVs marketed by LG, Sony, Panasonic, and more. Micro LEDs are more expensive to make than LEDs or
Overview of LED-Backlit LCDs. LED-backlit LCDs are essentially liquid crystal displays (LCDs) with a light-emitting diode (LED) backlight. LCD technology has been around for decades. Even today, though, all LCDs require a backlight to illuminate their liquid crystals and produce visual images. Without a backlight, an LCD wouldn't be able to
Mini-LED TVs are, in every other respect, the same as standard QLED TVs, so the same benefits apply to both: Screen sizes can be bigger, and prices can be lower than OLED TVs (for now, anyway). As
A direct LED backlight is a backlight whose LED matrix is positioned directly behind the panel. In contrast, If you don't care about power efficiency or the external appearance of the monitor/TV, then it's mostly a matter of choosing between better contrast and better brightness, plus there are the backlight and black uniformity
When a TV is described as "backlit," it means the light source comes from behind the screen, illuminating the pixels to create an image. This term is often used in contrast to "edge-lit" TVs, where the light source is located around the screen's edges.
LG's QNED TVs also boast 2,500 dimming zones to limit blooming and ensure light is directed where it should across your screen. This Mini LED tech is also seen in the TCL's 6-Series and 8-Series
Good value: Full-array is better for local dimming. As for the uniformity of the screen, it depends on the implementation. Some edge-lit TVs have more uniform blacks than some full-array TVs. Another thing that we check for, but doesn't affect our scoring, is seeing what backlight type the LED TV uses.
Replacing an LED backlight can vary greatly in cost depending on the type and size of the TV, as well as the availability and cost of parts. On average, it can range anywhere from $50 to $500 or even more. If a technician is needed to perform the repair, in addition to the cost of parts, labor costs can add up if the repair is more complex.
