LED screen VS LCD screen
1,LCD screens use a layer of liquid crystal to control the degree of light transmission, while LED screens use light-emitting diodes as a backlight.
2,LED screens have higher brightness because they use light-emitting diodes as backlight sources, which can emit light directly, while LCD screens use a liquid crystal layer to control the transmission of light, which will have a certain loss. Generally speaking, the brightness of LED screens can reach more than 1,000 lumens, while the brightness of LCD screens is generally between 300-500 lumens.
3,LED screens have a higher contrast ratio because they use light-emitting diodes as backlight sources, which can be switched on and off independently to achieve true black, while LCD screens use a liquid crystal layer to control the light transmission and cannot completely block the backlight, resulting in less pure black. Generally speaking, the contrast ratio of LED screens can reach 10,000:1 or even higher, while the contrast ratio of LCD screens is generally around 1,000:1.
4,LCD screens are relatively power-hungry because they use a liquid crystal layer to control the transmission of light. The better the display effect, the more power is required. LED screens are more energy-efficient because they use light-emitting diodes as backlight sources and can adjust the brightness as needed, thus saving energy.
5,LED screens have better color performance because they use light-emitting diodes as backlight sources, which can emit three basic colors: red, green, and blue, thereby combining more colors. LCD screens use a liquid crystal layer to control the transmission of light, and need to use color filters to separate and synthesize colors, which will have certain color differences and distortion.
6,The larger the screen size, the better the visual effect. LED screens have larger sizes because they use light-emitting diodes as backlight sources, which can be flexibly arranged and combined, while LCD screens use liquid crystal layers to control the transmission of light, requiring fixed glass substrates and thin-film transistors, making it difficult to achieve large sizes.
