The outdoor application with high resolution in small size

With the development of the outdoor LED display, the application scene of the display is no longer limited to large outdoor display that is installed on the big building or billboard that could be seen from hundred meters away. The application like small, let’s say less than 10m2, LED displays and billboards have sprung up in some new segment market.

Imagine the billboards on a pedestrian street, or a display on the wall of a storefront, by the high brightness of outdoor LEDs and real-time changing pictures and videos as its unparalleled advantages, the small LED displays could always take considerable advertising revenue. However small LED displays need small pixel pitch for high resolution which could not be realized by 10mm or even 6mm pixel pitch.

So Artemis ST 3.9 emerges as the times require.

High brightness

0~6000cd/m2 brightness, meet the brightness of the day from noon to night. 

Waterproof

IP65 front and IP54 rear, could be installed in any urban environment, no matter it is in or out of home.

Front or rear maintenance

Front maintenance makes the services much easier.

High resolution in small size

Take the Artemis ST 3.9 as example; it displays a standard 4:3 video with 1024x768 resolution in 12m2, and provides greater economic benefits with less cost in limited city resource.

Thin and light

Panel thickness 120mm. Saves installation space.

Panel weight 20kg with aluminum cabinet and 30kg/panel with steel cabinet. Easy delivery and installation.

About the current gain

Usually, the LED driving current value is achieved by setting the resistor of the Rext terminal of the driving IC, so that the display can meet the required brightness within a safe range, such as 6000cd/m2. But after years of using, the efficiency of the LED will degrade, which will cause the brightness decrease at the initial current value. If we want the brightness to be 6000cd/m2, the current gain is needed.

By adjusting the current gain value of the RGB on the Uni-Master software, the instructions are sent to the driving IC through the serial port. The brightness of the LED is adjusted by changing the drive IC output current value, thereby changing the Rext terminal voltage value of driving IC, which can increase the current value of 200%.

Take the Artemis XT 16mm with NICHIA 346KS as an example, the brightness gain can make the LED screen still meet the normal demand after 10 years of use.

The data came from the 10-year monitoring on a LED screen with an over 500 square meters in Xi'an.

If we use Artemis XT 16mm with 346KS on a American Standard billboard Bulletin size (14 'x48'), the brightness and power consumption are shown in the following diagram:

We set the initial current value to set the brightness to 7500 cd/m2. When the brightness of LED attenuates, the driving current of LED can be increased by the current gain function of UNI-MASTER, so that the attenuated LED reaches the expected brightness value. In the first five years, the brightness remains 7500 cd/m2 unchanged, and 5500 cd/m2 brightness after ten years are still available.

In this way the initial current can be set to 75% of the maximum current at the very beginning, and the brightness is increased by the current gain in the later period. In this condition, the LED is not always driven by the maximum current. The drive current reduces, the heat reduces as well, so the decay rate of LED will be reduced (shown below by the Nichia test). This means that LED can work for a longer time with a certain brightness, and its power consumption will be relatively lower.

The method of calculating the brightness of the LED display

The brightness of the LED display is assembled by the brightness of each LED.

Let’s have an example:

For a P16 display with 1R1G1B lamp LED and 1/2 scan mode, there are 3906 dots in 1m2. Let’s say the brightness of red LED is 800mcd; green is 2300mcd; blue is 350mcd. Then the brightness for 1m2 in theory is (800+2300+350) *3906/1000/2=6737.85cd/m2.

How to calculate the pixel brightness if we know the brightness and the density of pixels of the display?

The brightness of the red LED: brightness cd per m2 / pixels per m2 * 0.3

                               green LED: brightness cd per m2 / pixels per m2 * 0.6

                                 blue LED: brightness cd per m2 / pixels per m2 * 0.1

Example:

A display with 10000 pixels/m2, SMD, brightness 6000cd/m2,

Then the brightness of each LED:

Red: 6000/10000*0.3=0.18 cd

Green: 6000/10000*0.6=0.36 cd

Yellow: 6000/10000*0.1=0.06 cd

The brightness of each SMD LED=0.18+0.36+0.06=0.66cd.

LED Poster VS LCD Poster (2)

In terms of service life, the light flux attenuation of LCD display is fast, it needs to be replaced after running for about a year and a half generally, but the LED poster can run for more than five years in the same environment. Moreover, because of the splicing features of LED display, LED poster is easy to maintain and reduce the loss rate of equipment failure, which can greatly reduce the economic loss of the advertising operators.

               LCD Poster                                      LED Poster 

With the development of Internet, the new marketing methods such as two-dimensional code, LBS, even the latest NFC payment and so on, which are more and more popular among advertisers, LED displays are the best advertising carriers. You can also use interactive technology to enhance the interaction between LED poster and audience, such as touch screen and  cloud technology broadcast control management.

Based on the above advantages, the advertising market has a great potential demands for the LED poster, and it has shown great acceptance ability at this stage. Despite the market demands, in current, in the environment that the outdoor big screen market is becoming more and more saturated, LED posters break the boundary of display devices between big size display and small size display for the enterprise, and open a new outlet for the development of the industry.

LED Poster VS LCD Poster (1)

In the field of advertising display equipment, LCD display and LED display have not interfere with each other, and develop independently. Poster is a typical representative in the display field. LCD poster is close to the crowd, the media radiation range is less than one hundred square meters. LED poster spread a wide range, covering thousands of square meters of audience.

Compared with the LCD poster, LED poster break the restrictions that is only suitable for remote viewing. In size, LED poster is generally larger than the size of the LCD poster, usually 72 inches or more.

LCD Poster                                            LED Poster

However, LCD poster is generally 46 inches, 55 inches, 70 inches, the biggest can be 82 inches.The cost of LCD poster increases exponentially with the increase of size. More than 100 inches is more expensive. For advertising operators, the cost effectiveness is much smaller than the same size LED poster.

Besides this, LED poster is not easy to be obscured because of the large screen area, so it can carry more advertising information and bring a stunning visual effect. Moreover, the play content of the larger display area is more likely to reach the audience and maximize the profit of the advertisers.

From the perspective of comprehensive income, the cost of the LED poster is far less than LCD, but can receive more than twice  benefits of traditional LCD poster.

Therefore, LED posters are becoming more and more popular with users。
