What's the difference between LCD and led?

LED uses light-emitting diode as backlight

LED is more energy-saving, and the light of LED is softer and closer to nature

there is also an LED TV, which directly consists of many light-emitting diodes instead of backlight, so the color of TV is more natural and energy-saving, But the price is very expensive.
analysis of the difference between LED screen and LCD.
analysis of the difference between LED screen and LCD. It should be consulted when many customers buy small black recently.
what is the difference between the small black of LED screen currently on sale and the traditional small black of LCD screen before? LCD is the full name of LCD: it includes TFT, ufb, TFD, STN and other types of LCD.
TFT is commonly used in notebook LCD.
TFT screen is thin film transistor.
English full name is active matrix LCD, with special light tube on its back, This is also the origin of the so-called active matrix TFT, which can greatly improve the response time, about 80 ms, while STN is 200 ms! Compared with STN, TFT has excellent color saturation, reduction ability and higher contrast, and it can still see clearly in the sun, but its disadvantage is relatively power consumption and high costLED applications can be divided into two categories: one is led single tube applications.
including backlight LED, infrared LED and so on; At present, there is still a certain gap between China and the world in the manufacturing of LED basic materials, but as far as LED display is concerned, China's design and production technology level is basically in line with the international level.
LED display is a display device composed of LED arrays.
it adopts low voltage scanning drive.
it has the following advantages: low power consumption, long service life, low power consumption, low power consumption, low power consumption, low power consumption, low power consumption, low power consumption, low power consumption, low power consumption, low power consumption, low power consumption, low power consumption, low power consumption Compared with LCD, LED displays have many advantages in brightness, power consumption, viewing angle and refresh rate.
the power consumption ratio of led to LCD is about 10:1.
and the higher refresh rate makes led have better performance in video, which can provide a 160 ° viewing angle, It can display all kinds of text, numbers, color images and animation information, and also play TV, video, VCD, DVD and other color video signals. Multiple displays can also be broadcast on the Internet.
the single element reaction speed of organic LED display is 1000 times faster than that of LCD screen.
it can be taken care of in strong light, And adapt to the low temperature of minus 40 ℃.
LED technology can be used to produce thinner, brighter, clearer display than LCD, which has a wide range of application prospects.
simply put.
LCD and LED are two different display technologies, LCD is a display screen composed of liquid crystal, while LED is a display screen composed of light-emitting diodes.
compared with LCD display, LED display has a wide range of application prospects.
in short, LCD and LED are two different display technologiesLED has more advantages in brightness, power consumption, viewing angle and refresh rate, but the current technology is not very mature. After all, a mature product needs time and market test, The OLED display technology is different from the traditional LCD display.
it does not need backlight, and uses very thin organic material coating and glass substrate. When there is current, these organic materials will emit light.
and the OLED display screen can be made lighter and thinner.
the viewing angle is larger, However,
although OLEDs with better technology will replace TFTs and other LCDs in the future, organic light-emitting display technology still has some defects, such as short service life and difficulty in large-scale screen
