One, full-color led display prices and those things
Full-color led screen is one of the led screen, its picture is very clear, color is very rich, the use of red, green, blue three colors as the base color, so that the electronic screen has a high resolution, high saturation of the dynamic image.In terms of technology, non-linear correction technology is adopted to enhance the hierarchical sense of image. Full-color LED display can support a variety of display modes, which is very convenient to operate. Today, xiaobian will introduce some knowledge of full-color LED display to you.
1. Full-color led screen price is as follows:
P3.91 indoor full-color LED display, 4699 yuan;
P8 households with full-color appearance, 2800 yuan;
P10 outdoor energy-saving full-color LED display, 3,950 yuan;
P10 outdoor full-color LED display, 3,100 yuan;
P3 indoor full-color LED display, 5,800 yuan.
Compared with the single-color and two-color led type screen, its price can be more expensive, and the larger the screen size, the higher the color resolution, the denser the chromaticity, the more expensive it will be.Specific full-color led screen price needs to be determined according to the actual situation.


2. System composition of full-color led display:
Generally speaking, full-color led display screen is composed of display screen, video input port, computer special equipment and system software.The display signal of the computer is mainly received by the control circuit of the display screen. The control circuit can drive the led to emit light, thus generating a picture. At the same time, the sound can be output by adding power amplifier and speaker.The signal source of full-color Ed display screen can be video camera, video recorder, VCD player, etc., and its computer and special equipment have the function of determining the system function, which can choose different types according to the specific needs of users.Finally, the system software can provide dedicated playback software.
3. How to distinguish the quality of a full-color screen?
In the difference between the quality of full-color display screen, we need to judge through the following aspects.First of all, its brightness and visual Angle. The brightness of the full-color display screen indoors is generally over 800cd/m2, while that of the outdoor is 1500cd/m2. Only when the brightness is reached can the display screen work normally, otherwise, the brightness is too low to see clearly the displayed image.Led beads directly determine the brightness of the size.The larger the viewing Angle, the better. The encapsulation of the core determines the size of the viewing Angle to a certain extent.Then there is the white balance effect. One of the most important indicators of led display is the white balance effect, and the quality of the white balance effect is determined by the control system of led display.There is also its color reducibility, here the color reducibility is a little more popular led screen color reducibility how?Finally, it is the flatness, flatness is generally kept within a millimeter, so that the image can be displayed without distortion, the production process directly determines the flatness.
4. How about the price of full-color led display?
After knowing above content, everybody CARES most is its price.Full-color led displays have different brands, and different brands have different prices.The price of full-color led display of delenser brand is about 3600 yuan, while the price of full-color led display of other neng brands is relatively lower or higher. Generally, the sales price on the market is about 3500 yuan.Small make up also found that its model is different, the sales price is different.
Above is small make up to introduce some knowledge of full-color led display, now it is widely used in the railway station, bus station, gymnasium and exhibition venues, electric power, advertising and other industries, in addition, small make up remind everyone is even must regularly to maintenance of full-color led display, it can prolong the service life of it
Two, LED full color screen one square LED display power consumption is equivalent to how many watts
The maximum power consumption of outdoor LED screen (full-color) is about 800W/ m2, that is, when the outdoor LED screen reaches the maximum power (peak) every moment, the power consumption per square hour will be 0.8 KWH.The maximum power of each single red plate is 25w, and the power consumption of 16 plates is 150-200w.The actual situation depends on the size of your screen. Generally speaking, the power consumption of full-color LED screen is as follows:
1. Small spacing consumes the most electricity, with an average power consumption of 400-550w/m2 / h;2. Indoor conventional display screen, average power consumption 150-350 w/m2 / h;3. Outdoor conventional display screen, average power consumption 250-350 w/m2 / h;4. Energy-saving full-color display screen 75-150w/m2 / h
Iii. Matters needing attention in switching LED electronic display screen:
Switch sequence: when the screen is opened: turn on the machine first and then open the screen.Turn off the screen: first turn off the screen, then shut down
(turn off the computer and turn off the display screen first, which will cause high highlights in the screen body and burn down the light pipe, causing serious consequences.)
Switch screen intervals should be greater than 5 minutes. 
After the computer enters the engineering control software, the screen can be turned on and powered on. 
Avoid opening the screen in the state of full white screen, because the impact current of the system is the maximum. 
Avoid opening the screen out of control when the impulse current of the system is the maximum.A. the computer does not enter the control software and other programs;The computer is not energized;C. power supply of the control part is not turned on. 
When the environment temperature is too high or the cooling condition is not good, you should pay attention not to open the screen for a long time. 
Electronic display part of the body appears a line of very bright, should pay attention to close the screen in time, in this state should not be long screen. 
If the power switch on the display screen often trips, please check the screen body or replace the power switch in time. 
Check the fastness of the joint regularly.In case of looseness, pay attention to timely adjustment, re-reinforcement or renewal of lifting parts. 
According to the large screen display screen body, control part of the environment, to avoid insect bites, when necessary, should be placed anti-rat medicine.

Four, broken screen problem
To avoid possible problems, we can choose to passive protection and active protection, passive protection refers to some Internet cafes, dormitories and other public places the user can choose to buy display with toughened glass, this allows you to display "invulnerability, flame-resistant", but will have an effect to show colour, there will be reflective phenomenon;And active protection is to want to add caution more in the use at ordinary times, the article that causes harm to the screen as far as possible is far from the screen, and clean screen when also wipe gently as far as possible, reduce the possibility of harm to the minimum.
Five, the use of environmental considerations
Working environment temperature range - 20 ℃ or less t 50 ℃ or less and work environment humidity range between 10% and 90% RH;
Avoid using or storing in high temperature, high humidity, high acid/base/salt environment;
Keep away from inflammable goods, gas and dust;
Avoid strong collision and sharp collision during transportation;
When the environment temperature is too high or the cooling condition is not good, should pay attention not to open the screen for a long time;
LED displays that exceed the specified humidity will lead to parts corrosion, even short circuit and permanent damage when energized.
Screen body is prohibited from water, iron powder and other conductive metal.LED display screen should be placed in a low dust environment as far as possible, large dust will affect the display effect, and too much dust will cause damage to the circuit.If for any reason water, please immediately power off, until the screen body all components dry before use.
Six, cleaning attention
Regular cleaning and maintenance: the large LED full-color screen is exposed to the outdoor environment for a long time in the wind, sun and rain. Even if the indoor LED screen is exposed for a long time, more dust and traces of rain will accumulate on the screen, which requires regular and timely cleaning to avoid affecting the viewing effect.
If cleaning the surface of the module, please use a soft bristle brush and brush gently.Do not use any liquid material to clean the surface of LED module, otherwise LED beads may be damaged;
Correct wipe: the large screen surface of LED screen can be wiped with alcohol, or dust removal with a brush or vacuum cleaner, but not directly with a wet cloth.
Moisture proof and storage requirements
Storage temperature requirements: - 40 ℃ environment temperature t 60 ℃ or less, or less on the packaging, LED products must be stored in a temperature 30 ℃ and humidity < < 60% environment;
According to the display body, the control part of the environment, to avoid insect bites, when necessary should be placed rodent repellent.
LED screen cannot be turned off for a long time. If the screen body is not used for more than 3 days in a high humidity environment, each time the screen body is lit, the preheating lighting method shall be adopted: the brightness of 30%-50% shall be preheated for 4-8 hours, and then adjusted to the normal brightness (80-100%) to light up the screen body, so as to eliminate the moisture so that there is no abnormality in use;If the screen body is not used for more than 7 days, each time the screen body is lit, the pre-heating lighting method shall be adopted: the brightness of 30%-50% shall be preheated for more than 12 hours, and then adjusted to normal brightness (80-100%) to light up the screen body, so as to remove moisture so that there is no abnormality in use.
8. What is the difference between full-color led screen and LCD screen
The biggest difference between LCD and LED is that two different display technologies are applied. LCD is a display composed of liquid crystal, while LED is a display composed of LED.The main differences are also derived from this analysis.
First, brightness. The response speed of individual elements of LED screen is 1000 times that of LCD screen, and its brightness is also more advantageous than LCD screen. LED screen can also take care of under strong light, and adapt to the low temperature of minus 40 degrees Celsius.
Second, power consumption, power consumption is the most concerned point, LED power consumption and LCD, its ratio is about 10:1, in this respect, LED has a great advantage.
Third, the visual Angle, LCD display Angle limit is very big, this is a very busy headache, as long as the Angle of deviation is slightly larger, you can not see the original color, or even what can not see;And the LED can provide up to 160 ° Angle of view, advantage is great.
Fourth, the refresh rate, LED USES electricity to convert light energy, using injection principle, so its refresh rate is higher, and then better in video processing.
Fifth, contrast. Currently, the LCD screen with relatively high contrast is 350:1, but in many cases, it cannot meet various requirements, but the LED screen can achieve higher and more widely used.
Sixth, appearance, LED USES LED as the basis, compared with LCD, its display can make thinner.
LED display is more widely used than LCD display. It can display a variety of text, digital, color images and animation information. It can also play TV, video, VCD, DVD and other color video signals.
Eighth, service life, LED display can generally support about 100,000 hours, under normal circumstances, can use for decades, and LCD is much less.
Ninth, color, LED screen than LCD screen color is more real, this is because the LED TV gamut is much more than LCD.
