The Tri-Frame system consists of a three-point truss that was constructed solely for our P4+WH PRO. The newly developed Tri-Frame system of our PRO series provides an even simpler, safer and faster installation. Thanks to its depth, the triangular framework structure provides safety and stability, even with strong winds. Depending on the wind zone, span widths of up to 12 meters can be reached, without the need to fasten the LEDTEK LED wall horizontally several times. Our Tri-Frame system is the basis for the use of a Layher construction outdoors.

Horizontal and vertical viewing angle determine when colours and details remain entirely visible for the viewer. The bigger the angle, the more stable brightness and contrast stay with a sloping viewing perspective (left, right, top and bottom). The viewing angle maximum for the contrast is reached when the drop of the contrast ratio makes 1/5 of the initial value. It is important to have as large an angle horizontally and vertically as possible, so that the colours are displayed over the entire panel surface without any distortions. Modern SMD LED walls have a horizontal and a vertical viewing angle of 140°. Outside the viewing angle the colours tear off, the content of the display is often perceived as a bright (often pink) area.
The minimal viewing distance determines from what distance (m) the viewer does no longer recognize the individual LEDs but experiences the display as a homogenous area. As a guideline: the minimal viewing distance in meters is proportional to the pixel pitch in mm.
The difference to the minimal viewing distance is that the maximal distance in meters determines how big an LED wall should be approximately, so that one can make something out from afar. The guideline says that the viewing distance maximum to an LED wall per square meter increases by the factor 10. This means: the LED wall should with a distance of 100m be at least 10m2, so one can still make out details.

Order & Delivery
LED wall leasing
A prolonging of an actual leasing contract is possible under certain factors. If this is wished, you can contact the leasing partner directly.
The leasing rate is to be payed by the agreed date, the 1st or 15th of each month. The payment goes directly to the leasing firm.
The answer is no, as the speciality with leasing is that as a lessee, you do not pay off the LedTek LED wall. Only a monthly fee for the use is due.
Our LEDBRIX cabinets are available for leasing as well.
LED technology 1×1
Nit (unit symbol nt) is a unit of the light density. The word derives from Latin “nitere”: to shine. Nit is another expression for Candela per square meter. Candela (lat. candle) is an SI unit for light intensity. The light density of an area determines with what brightness the eye witnesses this area; it has a direct reference to the optical sensory perception. The human eye can realize a light density of a maximum of 20,000 cd/m2.
SMD means Surface-Mount Device and is an electronical component. An SMD display is an LED cabinet on which the red, green, and blue diode are attached bundled to the LED module.
Nowadays, most LED walls are built of SMD LEDs. An SMD LED pixel consists of three LEDs in the colours red, green, and blue, which are emerged to one single component, which is connected directly with the circuit board.
The fundamental advantages of SMD technology are the low depth and the from this resulting higher viewing angle (in part 140 degrees per horizontal and vertical). Since 2014, LEDTEK has been using almost exclusively SMD LEDs and offers pixel pitches starting from 2.6mm and from 0,93mm for our LEDBRIX. SMD LED series are nowadays almost always the better choice. Even outdoors, SMDs provide enough brightness and will replace DIP LEDs over the next years to a large extent. Furthermore, SMD LED walls offer in contrast to DIP LED walls qualitatively more high-end, flicker free and more stable images.
The frame rate is a term from film and video technology. It indicates the number of individual pictures that are taken or played per time span and is mostly specified by the unit fps (frames per second) or Hz (Hertz). The human brain realizes sequent images, starting at around 14 to 16 images per second, as a moving (but not necessarily smooth) scene.
To fill a LEDTEK LED wall with life, a programming beforehand is necessary. The broadcast eventually happens via a NovaStar controller.
LEDTEK offers all LED wall series as BL- and WH-series. LED cabinets of the BL-series offer a standard brightness up to ca 1500 Nits. All WH cabinets are offered as a daylight-suitable series with a brightness of ca. 4500 Nits. For more than 85 percent of all usages, the standard brightness is sufficient. However, if the LED wall is supposed to be exposed to extremely bright environments, like shop windows or outside in direct sunlight, the purchase of a WH-series can be reasonable. LEDTEK outdoor series are waterproof.
Usually LEDTEK LED cabinets to not have a difference in brightness. However, if this should be the case, it is because they were not part of the same batch. The brightness value for an entire LEDTEK LED wall can be determined e.g. with the controller.
It is difficult to determine the lifespan of an LED wall. Several factors play a role, e.g. the daily use, but also the environment of the LED wall. Bright images, as well as a high light intensity are a strain on the LED wall, of course more than dark images and a lower luminosity.
A videowall, consisting of several LCD screens, is clearly determined by one thing: black bars where the screens are placed next to one another. It divides the overall image into single, small segments. Here, LED walls have a clear advantage. They consist of single modules and cabinets that create an overall image; however, these stay invisible to the viewer, as the individual LED cabinets do not have these black bars along their edges.
If one of the LCD screens of a videowall is broken, the overall image is damaged as well. A whole segment stays black or shows some kind of fault. In this case, the broken screen needs to be exchanged. Should one of the diodes of an LED wall break, thus one of the many small lights on a wall, one might not even notice it in most cases and one can proceed as planned. In case the malfunction is noticeable, or several diodes are broken, the exchange of the cabinet is easily doable.
A big advantage of the LED cabinets is in their flexibility. Besides walls in different shapes, like especially long or scale-like installations, especially big installations are possible as well. Their implementation is in comparison to big videowalls especially easy to do.
The resolution of an LED wall is indicated in pixel (number of image points). It depends on the pixel pitch and the size of the LED wall. With the number of LEDs per square meter, the resolution increases accordingly. The display of the shown images improves, but the price per square meter of the LED wall increases as well.
Like this, an LED wall with a surface of e.g. 5x3m, with a pixel pitch of 2.6mm, has a resolution of 1920(w)x1152(h) pixels. Hence the resolution depends on the wall and its own pixel pitch.
The smallest unit to define an image point is a pixel. Three LEDs in the primary colours red, green and blue create a unity, a pixel. The more pixels available, the higher the resolution of the LED wall.
The pixel density is a unit for the number of LED lamps that are used per square meter. With a display size of e.g. 1x1m and a pixel pitch of 10 mm, there are 100 LED pixels used in each height and width. This means: the more pixels for the same size, the higher the resolution.
The NovaStar Image Booster helps with enabling more detailed image contents and more realistic colours. The capability of an LED wall can thus be utilized fully. You can read about the installation process of the NovaStar Image Booster here.
The Scan-Mode provides information on how many single LEDs are played by an IC. The mode is quoted in fractions. It means e.g. that with a ½ scan one IC controls two LED lamps, and with a ¼ scan four LEDs are played by an IC. With an increasing number of LEDs that are played by an IC, the brightness of the LEDs decreases. By using more expensive ICs, higher clock rates and lower scan-modes are realizable.
Horizontal and vertical viewing angle determine when colours and details remain entirely visible for the viewer. The bigger the angle, the more stable brightness and contrast stay with a sloping viewing perspective (left, right, top and bottom). The viewing angle maximum for the contrast is reached when the drop of the contrast ratio makes 1/5 of the initial value. It is important to have as large an angle horizontally and vertically as possible, so that the colours are displayed over the entire panel surface without any distortions. Modern SMD LED walls have a horizontal and a vertical viewing angle of 140°. Outside the viewing angle the colours tear off, the content of the display is often perceived as a bright (often pink) area.
The minimal viewing distance determines from what distance (m) the viewer does no longer recognize the individual LEDs but experiences the display as a homogenous area. As a guideline: the minimal viewing distance in meters is proportional to the pixel pitch in mm.
The difference to the minimal viewing distance is that the maximal distance in meters determines how big an LED wall should be approximately, so that one can make something out from afar. The guideline says that the viewing distance maximum to an LED wall per square meter increases by the factor 10. This means: the LED wall should with a distance of 100m be at least 10m2, so one can still make out details.
When constructing a LEDTEK LED wall, the various event situations and environmental influences are to consider compulsorily. This is why there are numerous possibilities to set up the individual LED cabinets. The correct protection is to keep in mind. A LEDTEK LED wall that was constructed incorrectly resp. badly secured can quickly become a health or life threat.
Statics consider the environmental factors like wind zones, place, etc. Without statics, a secure construction of an LED wall cannot be guaranteed.
DIN resp. DIN-norm is the abbreviation for “Deutsches Institute für Normung” (engl. German Institute for Standardisation). DIN stands for a voluntarily developed standardized standard of material and immaterial objects.
The DIN EN-62471 (equivalent to the European guideline 2006/25/EG) determines what the criteria for grading a light source are resp. what endangering might result. The assessment is not only for the emitted light.
