Difference between LCD display and LED display:
Difference between LCD display and LED display:1. Compared with LCD display, LED display has more advantages in brightness, power consumption, viewing angle and refresh rate.
with LED technology, thinner, brighter and clearer display can be produced.
the LED display has the advantages of high brightness, low power consumption and high refresh rate2. The power consumption ratio of LED and LCD is about 1:10.

The difference between LED and LCD

LED is more energy-saving.
LED is more energy-saving3. LED has higher refresh rate.
it has better performance in video.
LED has higher refresh rate4. Led offers up to 160 ° It can display all kinds of text, digital, color image and animation information, and can play TV, video, VCD, DVD and other color video signals.
it can also display all kinds of text, digital, color image and animation information5. The reaction speed of single element of LED display screen is 1000 times faster than that of LCD screen.
it can be taken care of under strong light and adapt to the low temperature of minus 40 ℃.
in short.
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.
LED is a display screen composed of light-emitting diodesExtended information:Future development trend of LEDThe LED display industry has developed rapidly.
it has also formed a new development stage.
it can be divided into three stagesLED display screen utility model stage: LED display screen has the characteristics of environmental protection, high brightness, high definition, high reliability and so on, which is gradually highlighted.
in the previous stage, LED display screen market only meets people's needs, but it can not meet the requirements in LED display screen products, and the quality is not up to standard.
in the last stage, LED display screen market only meets people's needsWith the development of LED display screen.
now LED products have a new breakthrough.
LED products have a new breakthroughAt least, it is more advanced than the previous stage.
it has also developed a series of products which are completely different from the traditional light source applications, and will be popular.
LED display will have a larger and broader development space.
LED display is not only a beautification function.
its variety makes it more suitable for people's work and life.
now, manufacturers have to work hard in the design application and technology research and development Advantages.
conclusionReference: Sogou encyclopedia LED display.
LCD is the full name of liquid crystal display.
it mainly includes TFT, ufb, TFD STN and other types of LCD.
TFT is commonly used in notebook LCD.
TFT (thin film transistor) refers to thin film transistor.
each LCD pixel is driven by a thin film transistor integrated behind the pixel, so that it can display screen information with high speed, high brightness and high contrast. It is one of the best LCD color display devices at present, TFT is now the mainstream display device on laptops and desktops.
compared with STN.
TFT has excellent color saturation, reduction ability and higher contrast. It can still see clearly in the sun, but its disadvantage is that it consumes more power and costs more.
TFT has the advantages of high color saturation, reduction ability and higher contrastLED is the abbreviation of light emitting diode.
LED applications can be divided into two categories: one is led display screen; the other is led display screen; The second is led single tube applications.
including backlight LED, infrared LED, etc.
now, as far as LED display is concerned.
China's design and production technology level is basically in line with the international level.
China's design and production technology level is basically in line with the international levelLED display screen is a 5000 yuan computer configuration unit composed of LED arrays.
it adopts low voltage scanning drive.
it has the following characteristics: low power consumption, long service life, low cost, high brightness, less faults, large viewing angle, long visual distance, etc.
it has the advantages of low power consumption, long service life, low cost, high brightness, long visual distance, etcThe difference between LCD and led1. Compared with LCD display, LED display has more advantages in brightness, power consumption, viewing angle and refresh rate.
using LED technology, thinner, brighter and clearer display can be produced.
in this paper, the design of LED display is introduced2. The power consumption ratio of LED and LCD is about 1:10.
LED is more energy-saving.
LED is more energy-saving3. LED has a higher refresh rate.
it has a better performance in video.
LED has a higher refresh rate4. LED provides a width of 160 ° It can display all kinds of text, digital, color image and animation information, and can play TV, video, VCD, DVD and other color video signals.
it can also display all kinds of text, digital, color image and animation information5. The reaction speed of single element of LED display screen is 1000 times faster than that of LCD screen.
it can be taken care of under strong light, and adapt to the low temperature of minus 40 ℃.
to put it simply.
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.
LCD and LED are two different display technologiesThe difference between LED display and LCD displayLED backlight: power saving (30% ~ 50% compared with CCFL).
high price, high brightness and saturationCCFL backlight: compared with LED backlight, it consumes a lot of power (still much less than CRT).
CCFL backlight can save a lot of powerCheap.
Screen difference: the color of LED backlight is bright.
the saturation is high (the natural light source of CCFL and LED is different).
how to distinguish: LED backlight will especially emphasize LED TV.
what is not emphasized is CCFL LCD TVThere are real led TVs on the market (they don't rely on backlight, but they will emit light actively). Sony and samgsung both have them, but their panels are under 11 inches and the price is very expensive. For example, Sony 11 inch AMOLED TVs charge about RMB18000, which belongs to the high-end market, So it's rare in the market.
let's take a look at the actual picture comparison diagram of the difference between LCD and led.
the following two notebook displays: the left one is CCFL backlit LCD, and the right one is led backlit LCD. The comparison under three colors of red, green and blue is as follows:The color difference between LCD screen and LED screen is not very big.
if you just pay a disproportionate price for the name of LED.
it's really unnecessary.
the color difference between LCD screen and LED screen is not very bigAt present, the LED display in the market is not the real LED display.
to be exact, it is the LED backlight LCD, and the LCD panel is still the traditional LCD. In a sense, it contains the quality of fraud.
for the LCD, the most important key is its LCD panel and backlight type, However, TFT panel is generally used in the LCD panel on the market, which is the same. The only difference between LED and LCD is that their backlight types are different: LED backlight and CCFL backlight (i.e. fluorescent lamp), which are diode and cold cathode lamp respectively.
LED backlight and CCFL backlight (i.e. fluorescent lamp) are different.
