What is the LED backlight?
Light emitting diode (LED) backlight combines liquid crystal display (LCD) with LED light source to generate paint on computer and television screens. LED backlight is required to produce light and color from behind the screen. This technology is capable of creating a wide range of colors and comes as a backlight system with an edge or local resolution. The use of the LED makes it easier for consumers and workers to look at the screen without eyebrows, although Eye Eye Cain still appears if the screen is constantly looking for several hours for several hours. The uniformity of the color is easy to maintain when the LEDs are new, but the ice tends to age at different speeds, so the color can change in one part of the screen.
In most screens, the need for light and color is needed backlight. This simply means that the screen is light and LCD is promoted. LCD cannot produce light and anything produces light, changes the properties of the screen.
in the LED backlighting, a number of small diodes that are either white - really blue with yellow phosphorus to create white because there is no white ice - or red green blue (RGB) ice. White is used on cheaper screens, while RGB can produce a higher variety of colors. LED backlights are mostly used for smaller screens, such as TVs and computers, because ice cannot produce the necessary amount of brightness for larger displays.
LED backlight comes in two varieties: marginal and local dimming. The marginal line guided strips along the edges of the screen, which means that the light of the light is directed to the center of the screen. This is cheaper, but it causes black to look gray. Local Twilight uses the LED grid on the entire screen, which means better color control - and black actually seems black.
on older screens, especially computers, bulb and fiber used to generate SVosta. This approach lights up the entire screen indiscriminately and created closed parts of the LCD, so it caused massive Eyestrain for users of computer and anyone else looking at the screen. The LED backlight only lights up the part of the screen, making it easier to look at the screen for a longer period of time. This can still cause eye spores, but chances are reduced.
The problem of LED backlight is that a large number of different diodes are used at a time. Each diode ages at a different speed due to the use of colors or different factors during production, so some lights will grow rapidly while others will age slowly. This means that part of the screen may seem dimmers because the LEDs are worn, causing uniform color uniformity.
