At present, the development of OLED is booming and has entered the public view. In addition to the relevant industry insiders, more ordinary consumers are also beginning to pay attention to this technology. What's the difference between OLED and the LED screen we discussed earlier? In fact, although there is a letter difference between LED display and OLED display, their imaging technology is completely different.

How to distinguish LED display from OLED display?

in this paper, the imaging technology of LED display and OLED display is introducedLed splicing large screenLED display is a collection of microelectronic technology.
computer technology and information processing. It is famous for its bright color, wide dynamic range, high brightness, long life, stable and reliable performance. It is also the most advantageous public display medium.
with the continuous development and innovation of LED display technology.
LED display industry starts with products, and then goes to product design, So that we can provide an overall solution in the future.
in the future, we can provide an overall solutionThe main advantage of LED display is that it has ultra-high brightness and large screen display.
it can meet the needs of outdoor all-weather and full-color display. With LED color large screen, it can show the sky and sea, and realize three-dimensional animation.
LED display can be assembled into various structures according to pixel size.
the diameter of small pixel is generally less than 5mm, and full-color display needs three T-1 red, green and blue lights, Or assemble a multi chip T-1 (34) The LED lamp is used as a pixelOLED displayOLED can be called organic light-emitting diode or organic light-emitting display.
as an emerging application technology in the field of display, OLED has the advantages of self illumination, no backlight, high contrast, uniform image quality, wide viewing angle, fast response speed, and meets the principle of short information. It is very suitable for small and medium-sized panels It has been widely recognized in the fields of VR and so on.
it has been widely recognized in many fieldsIn addition.
in additionBecause OLED is an all solid state, non vacuum device, which has the characteristics of shock resistance and low temperature resistance, it also has important applications in the military field.
due to the rapid development of the downstream market, such as smart phones, tablet computers, car audio and other industries.
led to the rapid growth of OLED display industry, the future market scale is immeasurable. LED display is a display mode by controlling the semiconductor light-emitting diodes, which is usually composed of multiple red light-emitting diodes. The LED display is dominated by the light on and off, so as to realize the text, graphics, images, animation, video Video signals and other information display screen.
while OLED is driven by current to emit light through the organic film itself.
the light emitted can be red, green, blue, white and other monochromatic, and then achieve full-color effect, which belongs to a new light-emitting principle.
.
the materials used are different. Led uses metal materials.
while OLED uses organic materials; OLED is more advanced, it does not need light irradiation can be self luminous, better contrast, usually with LED is to have backlight irradiation to see thingsOLED and LED are not the same concept.
but actually they describe completely different things.
we all know that liquid crystal panels emit light through backlight.
various colors are produced through the refraction of liquid crystal molecules. Liquid crystal molecules can not emit light themselves, while led only refers to backlight.
and OLED can emit light itself.
therefore, backlight is not needed.
LED is a kind of backlightHope to adopt.
wish you a happy life
