The main question is not to ask LED display and LCD display which is better ah, find the answer as follows!
The main question is not to ask LED display and LCD display which is better ah, find the answer as follows!LCD is the full name of liquid crystal display, mainly including TFT, ufb, TFD and STNTFT is commonly used in notebook LCDTransistors refer to thin film transistors.

Which is better, LED display or LED display

each liquid crystal pixel is driven by a thin film transistor integrated behind the pixel, so that the screen information can be displayed with high speed, high brightness and high contrast,TFT is one of the best LCD color display devices at present, and is the mainstream display device on laptops and desktops.
compared with STN.
TFT has excellent color saturation, reduction ability and higher contrast, which is too lowIt's still very clear under the sun, but the disadvantage is that it consumes a lot of power, and the cost is also high.
the price of electricity is highLED is light emitting diodeLED 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 and so on.
now, as far as LED display is concerned.
inChina's design and production technology level is basically in line with the international level.
LED display is a 5000 yuan computer configuration sheet composed of LED arrays.
it adopts low voltage scanning drive.
it has the advantages of low power consumption and low costIt has the characteristics of long service life, low cost, high brightness, few faults, large viewing angle and long visual distanceDifference between LCD and LED (Hubei Mingzhi Photoelectric Technology Co., Ltd.)1. LED display compared with LCD display.
2LED has more advantages in brightness, power consumption, viewing angle and refresh rate.
LED technology can be used to produce thinner, brighter and clearer displays than LCD.
this paper introduces the development of LED technology2. 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 much less power (still much less than CRT).
Screen difference: LED backlight has bright color.
high saturation (CCFL and led have different natural light source).
how to distinguish: LED backlight will emphasize LED TV.
what is not emphasized is CCFL LCD TVThere are real led TVs on the market,Sony and samgsung have both, but their panels are currently under 11 inches,And the price is very expensive. For example, the TV of Sony 11 inch AMOLED costs about RMB18000, which belongs to the high-end market, so there are few on the market.
the price of the TV is very highLet'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, which are red and red respectivelyThe comparison of 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. The LCD is still the traditional LCD, in a senseFor LCD, the most important thing is the type of LCD panel and backlight. The LCD panel on the market generally adopts TFT panel, which is the same as LED panelThe only difference between LED and LCD is that they have different backlight types: LED backlight and CCFL backlight (i.e. fluorescent lamp), which are diode and cold cathode lamp respectively.
.
compared with LCD, LED displays have higher brightness, power consumption, viewing angle and refresh rate, The power consumption ratio of LED and LCD is about 10:1.
and the higher refresh rate makes led have better performance in video, which can provide up to 160 bandwidth ° From the perspective of,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 it can adapt to the low temperature of minus 40 ℃.
LED technology can produce thinner, brighter and clearer display than LCD, which has a wide range of application prospects.
in short,
LCD and LED are two different display technologies, LCD is a display composed of liquid crystal, However, LED is a display screen composed of light-emitting diodes.
compared with LCD, LED has more advantages in brightness, power consumption, viewing angle and refresh rate      LED display screen is not suitable for home use.
one is too expensive, and the power consumption is too high, so it is not popular.
