unic uc46 lcd panel free sample

The UNIC UC46 is the company’s latest compact projector. Boasting similar specs to the company’s popular UC40 model, the new model adds improved cooling and UNi-Link, a feature that allows you to stream multimedia via wifi.

The design of the UNIC U46 is predictably similar to its predecessor. Essentially a large black box, the device definitely nails the projector aesthetic. There’s a subtle geometric design on the top now that looks nice and helps give the projector some style cred.

There’s a fan to keep the unit cool and it’s not particularly quiet. Thankfully, it’s slightly quieter than UNIC UC40 but you’ll definitely be able to hear it during quiet scenes.

One thing to note is that the UNIC UC46 doesn’t seem to have any onboard memory. Settings will be saved as long as you keep the unit plugged in but it seemed to reset itself as soon as I unplugged it from the wall. That’s not an issue if you’re keeping the projector in one place but could be an issue if you’re wanting to transport it around.

Normally, I’d review a projector describing looking at the picture quality relative to something like an LCD TV. However, that’s really not fair to a sub-$100 projector that won’t even get close to units 10 times the price.

The UNIC UC46 boasts 1200 lumens of brightness but that’s still not enough to overpower ambient light. I wouldn’t bother trying to use the projector in a well-lit room.

When I reviewed the UNIC UC40, I complained about the transparent UNIC logo constantly in the top right corner of the screen – even over video. Thankfully, common sense has prevailed and the UC46 doesn’t exhibit the same flaw. You’ll just get unadulterated images.

The UNIC UC46 also boasts on-board sound for an all-in-one setup. However, the unit’s tiny 1.5W downward-firing speaker predictably sounds hollow and lacks bass. It’s functional but I’d strongly recommend taking advantage of the 3.5mm output jack to connect the projector up to a better quality speaker like the Blitzwolf F1 Bluetooth speaker.

The biggest feature of the UNIC UC46 is “UNi-Link” – UNIC’s wifi-based solution for streaming content straight to the projector without any wires. Miracast, DLNA and Airplay are supported, covering off the most common standards.

For its price, the UNIC UC46 is a real bargain. As long as you have realistic expectations of a projector that costs only $75, the UNIC UC46 checks a surprising amount of boxes. Whilst the DVD resolution is on the low side, it’s sufficient for watching movies or playing games on. Combine that with the in-built media player and Uni-Link wifi streaming functions and you’ve got a great package for cheap entertainment.

The UNIC UC46 improves on its predecessor in every way. Whilst it won"t blow you away with its image quality, it"s an impressive unit for under $100 and a cheap way to get some big screen action going.

An LCD projector is a type of video projector for displaying video, images or computer data on a screen or other flat surface. It is a modern equivalent of the slide projector or overhead projector. To display images, LCD (liquid-crystal display) projectors typically send light from a metal-halide lamp through a prism or series of dichroic filters that separates light to three polysilicon panels – one each for the red, green and blue components of the video signal. As polarized light passes through the panels (combination of polarizer, LCD panel and analyzer), individual pixels can be opened to allow light to pass or closed to block the light. The combination of open and closed pixels can produce a wide range of colors and shades in the projected image.

Because they use small lamps and the ability to project an image on any flat surface, LCD projectors tend to be smaller and more portable than some other types of projection systems. Even so, the best image quality is found using a blank white, grey, or blackprojection screens are often used.

Early experiments with liquid crystals to generate a video image were done by John A. van Raalte at the RCA-Laboratories in 1968.CRT with a modified faceplate to generate a charge pattern on its surface. No practical application of this concept for projection purposes is known. However, a similar concept was used for print heads without an LCD.

The first experiments with a direct-driven, transmissive matrix-addressed LCD using a converted slide projector by Peter J. Wild working at Brown Boveri Research in Switzerland were conducted in 1971. A projector was shown in operation at the SID Conference 1972 in San Francisco.thin-film transistors) at the matrix intersections) were not capable of displaying images with sufficient resolution for video pictures, a combination of a fixed image together with an LCD matrix for the variable elements was proposed as an LC projector for certain control room applications,

A lot of effort went into optimizing thin-film transistors (TFT) suitable for active matrix-addressed (AM) LCDs. The concept was invented and early trials were conducted by teams at RCA and Westinghouse Electric. T Peter Brody left Westinghouse and founded Panelvision in 1981 to manufacture AM LCDs. Breakthroughs occurred elsewhere in new materials and thin-film structures, with Hitachi of Japan as a pioneering company. Such AM LCDs became commercially available in the early 1980s.

Gene Dolgoff had the idea of using LCDs as light valves in projectors. However, he had to wait until 1984 to get a digitally-addressable LCD matrix device with sufficient resolution and contrast, which is when he completed building his LCD video projector. After building it, he saw many problems that had to be corrected including major light losses and very noticeable pixels (sometimes referred to as the "screen-door effect"). He then invented new optical methods to create efficient and bright projectors and invented depixelization to reduce the screen-door effect.

At about the same time, the German company "Bonner Ingenieurbüro für Optoelektronik CrystalVision" started experimenting with LCD projection devices from 1985 onwards. Although traditional slide projectors already used infrared filters to reduce heating of the photographic slides, LCDs are much more sensitive to overheating. When the temperature in the nematic liquid crystal layer reaches the "clearing point" (i.e. enters the isotropic phase), the LC light valve does not work anymore until the temperature drops below again. Bernt Haastert, an engineer working at CrystalVision, found out, that placing the required polarizing filters at a certain distance on both sides of the LC cell allowed for efficient air cooling of the arrangement.

With patents filed worldwide (filing his first LCD video projector patent application in 1987), Dolgoff started Projectavision, Inc. in 1988, as one of the world"s first dedicated LCD-projector companies, which he took public on Nasdaq in 1990. He licensed the technology to other companies including Panasonic and Samsung. Early pioneers of LCD projection in Japan were Epson and Sharp,

Since 2005,Epson and Sony. Epson owns the technology and has branded it as "3LCD". To market 3LCD projector technology, Epson also set up a consortium called the "3LCD Group" in 2005 with other projector manufacturer licensees of 3LCD technology that use it in their projector models.

Early LCD systems were used with existing overhead projectors. The LCD system did not have a light source of its own: it was built on a large "plate" that sat on top of the projector in place of transparencies. This provided a stop-gap solution in the era when the computer was not yet a universal display medium, creating a market for LCD projectors before their current main use became popular.

This technology was employed in some sizes of rear-projection television consoles when there was a cost advantages in mid-size sets (40- to 50-inch diagonal). In 2014, 60-inch 1080p flat panel televisions were less costly than a projector with 1080p native resolution. Projection systems were typically marketed as offering a diagonal image size of 100 to 300 inches.

In 2004 and 2005, LCD front projection began a comeback with the introduction of the dynamic iris and other modifications that have improved perceived contrast to levels similar to DLP.

The basic design of an LCD projector is frequently used by hobbyists who build their own DIY (do-it-yourself) projection systems. The basic technique is to combine a high color-rendering index (CRI) high-intensity discharge lamp (HID lamp) and ballast with a condenser and collector Fresnel lens, an LCD removed from a common computer display and a triplet lens.
