Trend 2018: LDT Beamer vs. LED Beamer vs. DLP Projector

Nowadays beamers re used not only for presentations, demonstrations and lessons, but also as handy “multi-talents” at home, for example, instead of a TV-set. These projectors are especially handy when showing a movie on a projection screen to a small group of people. Movie-night lovers can experience a real cinema feeling.

projektorenAt work or education facilities, the projectors are still used for reflecting a PC, notebook or another multimedia terminal device onto a large screen.

There are many various models and types ranging from functional high-performance stationary projectors up to mobile small gadgets for presentations or home-cinema systems.

DLP Beamer: Digital Light Processing

In the event of a DLP projector, a DMD (digital micro-mirror device) is used as an image converter. This is an integrated circuit that provides a tilting micro-mirror for each image point. The micro-mirrors are controlled by electrical pulses. The mirrors can only accept two states: ON or OFF.

For this kind of image formation, the brightness gradations can only be achieved by very fast switching-over of the tilting micro-mirrors.

The DMD device can project all three primary colours one by one, with the aid of a rapidly rotating colour wheel. Current DLP video projectors use six or seven colour segments in a single colour wheel. High-performance DLP projectors are still used in cinemas.

Advantages of the DLP beamers:

  • High speed
  • No after-glowing of the image
  • No burning-in of still images
  • Higher contrast than on an LCD beamer
  • Almost no pixel artefacts
  • Less sensitive to dust, because the optics is encapsulated

Disadvantages of the DLP beamers:

  • If the colour wheel does not run fast enough, it may be a rainbow effect
  • Individual colours might flicker
  • Higher noise emission by the colour wheel and fan
  • Optimal image resolution depends on the type of the installed mirror matrix

LED Beamer: Light Emitting Diode

In these video projectors, the image is still generated by a DLP element or, in newer models, by a LCD (Liquid Crystal Display). LEDs are used just as sources of light. In this type of beamers, the colours themselves are generated by a sequential flashing of each individual LED.

A LED beamer is an ideal solution for mobile use, for example, a visual support or illustration of a business speech. In this case, the light wave length is between 540 and 610 nanometres.

Advantages of the LED beamers:

  • Higher energy efficiency
  • Lighter construction, since active cooling is not a must
  • Due to the low energy consumption, it can also be operated with a battery
  • Noise emission is significantly lower, because there is one wheel less

Disadvantages of the LED beamers:

  • LCD as an imaging device can only achieve a satisfactory pictorial quality with a fixed resolution
  • The total light output is lower
  • In the case of luminous flux reduction, the image continuously darkens. This loss of brightness can only be compensated by adaptive increase of current
  • Rainbow effect, because the basic colours are projected one by one

LDT Beamers: Laser Display Technology

Laser beamers initiate formation of images by a laser beam rapidly deflected and modulated. With a LTD beamer, the image is written on the large screen line by line.

As a result, the projector achieves a much better image quality. A special scanner with a facet mirror provides for formation of lines, whereas the tiling mirror initiates the next line feed.

The modulated laser beam can determine the correct brightness and colour for each image point. Appropriate security mechanisms ensure a trouble-free operation, so that the operator is not afraid of the laser.

Advantages of the LDT beamers:

  • Large contrast range
  • High light output is possible
  • Long service life of the light source
  • Basic colours are mixed to an overall image

Disadvantages of the LDT beamers:

  • High purchase price
  • In the case of high performance laser projectors, there is a danger for eyes without personal protection equipment
  • Speckle patterns may occur

We recommend different beamers and technologies, depending on the type or place of use.You can hardly find a beamer suitable for each situation and at each location.

Brilliance and Quality: Projector Series IN110v

The IN110v projector series, consisting of 3 different models, especially impresses with its high-quality appearance, light weight, strong contrasts and an adequate price-performance ratio. The mobile and practical all-rounders IN112v, IN114v and IN116v simply offer everything needed for an unparalleled presentation of images, videos and other files in excellent and brilliant quality.

IN112v, IN114v, IN116v – Projectors with All the Trimmings

All three models in the IN110v projector series are suitable for travel, since the beamers are small, handy, compact and light, but even so, power and performance are not sacrificed.

The 3D-enabled projectors can reproduce digital content from various sources: PCs, Blu-rays or even DVDs, in vividly clear colours. The impressive light intensity of up to 3,500 lumens and the powerful BillantColor technology contribute significantly to the overall effect.

Moreover, the three models (IN112v, IN114v and IN116v) deliver perfect black-and-white values even in the bright ambient light often found in training or conference rooms. This is possible due to an extremely high contrast ratio of 17,000:1.

Full and Undivided Attention Ensured with the IN110v Projector Series

Especially while presenting lectures, having the audience’s full and undivided attention is of great importance. With and of the three projectors in the IN110v series from InFocus, it is possible to consistently draw the attention of the audience to the lecturer with the aid of a remote-controlled dimming function, referred to as “eco-blanking”.

At the same time, by activating the the eco-blanking function, the lamp power is reduced by 30%, leading, in turn, to an increased lamp life by up to 10,000 hours. Moreover, no filter change is necessary. Due to the long service life and trouble-free operation, the operating costs of this series are always under control.

Circuit Points and Resolutions of 3 Multi-talented Projectors

circuit points projector series IN110vAll 3 projectors in the IN110v series, IN112v, IN114v and IN116v an be connected to any HDMI-enabled device via a HDMI port. Another advantage of this series is that all 3 models can also be wirelessly connected with terminal devices via optional LiteShow4 adapters. So, it becomes possible to quickly and easily exchange data, audio and video via a secure WLAN connection. With the LiteShow4 Adapter, iOS or Android mobile devices can be connected to the projector via the MirrorOP app. The LiteShow4 Adapter is thus a useful extra, but not part of the standard scope of the IN110v series.

The difference between the three different models is their resolution. Each model comes standard with an impressive light output of 3500 lumens and a high contrast ratio of 17,000:1, however, the resolution varies by model:

  • IN112v has a SVGA resolution (800×600)
  • IN114v can impress with its XGA resolution (1024×768)
  • IN116v leads the pack with a WXGA resolution (1280×800)

With a two-year warranty for the projectors and six months warranty on all lamps, the series are presented at a favourable price. The IN110v series projectors reproduce sharp images onto any kind of surface – whether a whiteboard, pale walls or black panels. So, each presentation becomes an unforgettable pleasure for everyone.
