LED screen has more LEDs than ordinary LCD screen.
The LED screen has more LEDs than the ordinary LCD screenThe color restoration degree is much better than that of LCD.
the picture looks more delicate and lifelike.
the color restoration degree of LCD is much better than that of LCDMoreover, the life of LED screen is at least twice as long as that of LCDSo the general LED screen is a little more expensive than the LCD screen.

What is the advantage of LED backlight over ordinary screen?

sometimes it's a lot more expensive@However, if there are no special requirements, you can use the LCD screen.
if there are no special requirements, you can use the LCD screenHope the answer will help you it accounts for about a quarter of the cost.
however, some friends may not understand the advantages and disadvantages of LCD and led.
therefore, this paper focuses on the differences between the two.
this paper mainly introduces the advantages and disadvantages of LCD and led         1、 Classification and main features of LCD        LCD is the full name of LCD.
there are mainly TFT, ufb, TFD, STN and other types of LCDTFT is commonly used in notebook LCD screens.
TFT screens are thin film transistors.
TFT screens are active matrix LCD displays. Special light tubes are set on the back of TFT screens to actively control each independent pixel on the screen. This is also the origin of the so-called active matrix TFT. This can greatly improve the response time, which is about 80 ms, Compared with STN,
TFT has excellent color saturation, reduction ability and higher contrast. It can still see very clearly in the sun, but the disadvantage is that it consumes more power and costs more         2、 Classification and main features of LEDLED is light emitting diode   Emitting   The abbreviation of code.
is the abbreviation of codeLED applications can be divided into two categories: one is led single tube applications.
including backlight LED, infrared LED, etc; The other is the LED display screen.
the LED display screen is the most important one       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 synchronized with the international level.
LED display is a display device composed of light-emitting diode arrays.
it adopts low-voltage scanning drive.
it has the following advantages: low power consumption, long service life, low cost, high brightness, less faults, high reliability, low cost, low cost, low cost, low cost, low cost, low cost, high brightness, low cost, low cost, high reliability, low cost, low cost The visual angle is large and the visual distance is long.
the visual angle is large and the visual distance is long       3、 Main differences between LCD and ledCompared with LCD, LED display has more 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 up to 160 bandwidth ° 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.
moreover, the reaction speed of single element of LED display is 1000 times faster than that of LCD screen.
it can be looked after in strong light, And it can adapt to the low temperature of minus 40 ℃.
LED technology can be used to produce thinner, brighter and clearer display than LCD, which has a wide application prospect.
LED technology can be used to produce a thinner, brighter and clearer display than LCDTo 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 technologiesCompared with LCD display,
LED display has more advantages in brightness, power consumption, viewing angle and refresh rate.
