LCD is the full name of LCD: it includes TFT, ufb, TFD, STN and other types of LCD.
LCD is the full name of liquid crystal display: it includes TFT, ufb, TFD, STN and other types of liquid crystal display.

TFT is commonly used in notebook liquid crystal display.

Notebook display: what's the difference between LED and TFT? Which is better?

TFT screen is thin film transistor.
English full name is thinfilm transistor, which is an active matrix type liquid crystal display. Special light tube is set on its back to 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. It can still see clearly in the sun, but its disadvantage is power consumption, And the cost is high.

LED is the abbreviation of light emitting diode.

LED applications can be divided into two categories: one is led single tube applications.
including 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 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, low cost, low cost, low cost and high cost Compared with LCD display, LED display has the advantages of high brightness, less faults, large viewing angle and long viewing distance,Both have more advantages.
the power consumption ratio of led to LCD is about 10:1.
moreover, the higher refresh rate makes led have better performance in video, can provide a 160 ° wide viewing angle, can display various text, digital, color images and animation information, and can also play color video signals such as TV, video, VCD and DVD, 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.
it can be looked after under strong light and adapt to the low temperature of minus 40 degrees.
using LED technology, thinner, brighter and clearer displays can be produced, It has a wide range of application prospects.

in brief.
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 the advantages of brightness, power consumption, viewing angle and refresh rate, OLED: organic light emitting display.
organic light emitting display (OLED) is a new type of Mobile LCD, which is known as "dream display."
OLED display technology is different from traditional LCD display.
without backlight, it uses very thin organic material coating and glass substrate, and when there is current passing through, it is easy to use, These organic materials will emit light.
and OLED display screens can be made lighter and thinner.
the viewing angle is larger, and power can be saved significantly.
however.
although OLED with better technology will replace TFT and other LCDs in the future,However, organic light-emitting display technology still has some defects, such as short service life and difficulty in large-scale screen
