It's really hard to answer this question. We should say the advantages and disadvantages, and we should look at the question in two parts, and we should also look at who to compare with;First of all, LED display, LCD display and CRT display can be classified into the same categorySecondly, CRT is gradually eliminated because of its bulkiness. At present, it mainly includes LCD and led;The advantages and disadvantages of the two are listed as follows:1. LCD is easy to break, LED is more solid;2. LCD can be miniaturized while LED can be large;3. Low brightness of LCD and high brightness of LED;4. High definition of LCD and low definition of LED;5. LCD has good effect in close range and LED has good effect in long range;6. To sum up, the existence of the two is reasonable, but they play an important role in different fields it is also energy-saving and environment-friendly.

What are the disadvantages of LED display?

the box is light in weight.
the box is light in weightThe box structure is made of aluminum alloy, which is very light.
the design of the box structure is simpleIt is beautiful, not easy to deform, easy to assemble and flatIt is suitable for rental companies.
car screen and mobile media.
it is suitable for rental companiesThe column installation or wall installation can reduce the pressure of the screen on the steel structure.
the results show that the column installation or wall installation can reduce the pressure of the screen on the steel structure2、 Wide perspectiveThe outdoor surface pasted full-color screen not only has a wide viewing angle of more than 110 degrees in the horizontal direction.
the outdoor surface pasted full-color screen has a wide viewing angle of more than 110 degrees in the horizontal directionIt also has a wide viewing angle of more than 110 degrees in the vertical direction.
it has a wide viewing angle of more than 110 degrees in the vertical directionThis is especially advantageous in some application places.
for example, building screens and outdoor LED displays hanging in the air need a wider perspective to show better advertising effect.
the advertising effect of the outdoor LED displays is better than that of the outdoor LED displays3、 High contrastBecause of the three in one design structureThe full-color SMD is small in size.
the size of the full-color SMD is smallTherefore, the luminous area is small and the area of black area is large.
the results show that the luminous area is small and the area of black area is largeThe contrast of LED display screen is improved.
the contrast of LED display screen is improved4、 Automatic production.
lower cost and higher productivityThe surface mounted LED can use the full-automatic placement machine for automatic placement, with high production efficiency.
the surface mounted LED can be used for automatic placementThe circuit design of LED outdoor surface mounted display module can realize the integration of light board and drive board.
the circuit design of LED outdoor surface mounted display module can realize the integration of light board and drive boardThe cost is reduced.
the reliability is improved and the production efficiency is improved.
the cost is reduced5、 Good light mixing.
suitable for close viewingBecause the design structure is three in one, the distance between the three chips is very close, and the light is mixed in the same bracket bowl instead of three discrete elliptical LEDs, the red, green and blue light mixing effect is better than that of the in-line elliptical LED screen, which is especially suitable for close viewing.
this paper introduces the design method of the LED screen6、 Good light distributionThe matching consistency of red, green and Blue Oval LEDs at different angles is a very difficult index.
the results show that the matching consistency of red, green and Blue Oval LEDs at different angles is a very difficult indexThe design structure of full-color SMD is a three in one structure.
the red, green and blue chips are all in one support bowlTherefore, the matching consistency of red, green and blue brightness at different angles is highly consistent.
thus, the brightness matching consistency of outdoor full-color surface mounted LED display screen at any angle is very good, and better color fidelity effect is achieved.
in this way, the brightness matching consistency of outdoor full-color surface mounted LED display screen at any angle is very goodDisadvantages of LED display:It also has relatively good optical effect.
no matter which one it is.
since it is outdoors, it must have the advantages of waterproof, moisture-proof and UV protection. However, these factors will still have an impact on the service life of LED display screen. Any product has a service life, and how to improve it is a problem that has been constantly solved.
in this paper, the design of LED display screen is introducedPowerful giant color photoelectric.
