There are seven main differences between LCD and led. If you know the difference, you will know how to distinguish them
There are seven main differences between LCD and led. If you know the difference, you will know how to distinguish them1. ContrastThe LED LCD can change the light intensity very quickly, so the brightness of the backlight can be adjusted according to the brightness demand of the local image, so the dark image can be darker, and the dynamic contrast can be much higher than that of the LCD.
especially for the direct LED backlight.

How to distinguish led and LCD screen

the improvement of the dynamic contrast is more obvious.
the dynamic contrast of the direct LED backlight can be improved2. Color gamutThe direct down LED backlight with independent three primary color LCD has a wider color gamut than that of LCD.
the backlight with independent three primary color LCD has a wider color gamut than that of LCD3. SizeThe thickness, volume and weight of TV can be reduced by using LED backlight.
the edge LED can be less than 1cm.
the thickness of TV can be reduced by using LED backlight4. Energy consumptionThe power consumption of LED backlight is 20% - 50% less than that of LCD in low and medium luminosity.
in addition to dynamically dimming the LED LCD according to the scribing image5. Life spanThe life of LED backlight is much longer than that of LCD.
the life of LED backlight is much longer than that of LCD6. Environmental protectionThe backlight of LED LCD screen is more environmentally friendly than that of LCD screen.
the backlight of LED LCD screen is lighter in weight.
less fuel is consumed during transportation.
the backlight of LED LCD screen is more environmentally friendly than that of LCD screen when it is disposed.
because LCD screen contains trace mercury.
it has a longer life and reduces waste generation.
the backlight of LED LCD screen is more environmentally friendly than that of LCD screen7. CostThe production cost of LED backlight is much higher than that of LCD.

LED is the abbreviation of light emitting diodeLED applications can be divided into two categories: one is led single tube applicationsIncluding backlight LED, infrared LED, etc; 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 levelLED display screen is a display device 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 viewing distance, etc.
it has the advantages of low power consumption, long service life, low cost, high brightness, less faults, long viewing distance, etcCompared 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 can 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 also be looked after in strong light, And adapt to the low temperature of minus 40 degrees.
using LED technology.
can produce thinner, brighter, clearer display than LCD, has a wide range of application prospects.
LCD is the full name of LCD: it includes TFT.
ufb, TFD, STN and other types of LCDTFT is commonly used in notebook LCD screen.
TFT screen is thin film transistor,It's an active matrix LCD with a special light tube on its back, which can actively control each independent pixel on the screen. This is also the origin of the so-called active matrix TFT, which can greatly improve the response time, about 80 ms, while STN's 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 the disadvantage is that it consumes more power, and the cost is also higher.
compared with STN, TFT has excellent color saturation, reduction ability and higher contrastIn short,
LCD and LED are two different display technologies. LCD is a display screen composed of liquid crystals, while LED is a display screen composed of light-emitting diodes.
compared with LCD, LED displays have more advantages in brightness, power consumption, viewing angle and refresh rate.
