LG’s new Cinema 3D Passive 3D Monitors, the D41P and D42P Series

April 26th, 2011 · 8 Comments · General 3D News

LG Electronics just announced the release of two Cinema 3D monitors series – D41P and D42P – using LG’s new Film Patterned Retarder (FPR) 3D technology (passive polarization filters) that was just recently announced in the new line of LG Cinema 3D HDTVs. LG claims that with their FPR 3D technology, the 3D monitors offer brighter and clearer images, and a “Flicker-Free” certified 3D picture that according the company makes 3D viewing more comfortable and eliminates the “occasionally caused dizziness and nausea among viewers” when watching 3D monitors using shutter glasses. You should however consider the fact that the flicker with shutter glasses is not the only thing that may lead to side effects and unpleasant feeling in the viewer, badly made stereo 3D content is actually the most usual cause.

Out of the first four monitors from the new D41P and D42P series – D2341P, D2242P, D2342P, D2542P, only the first one comes with just D-SUB and DVI-D connectivity (D2341P) and the other 3 models also feature support for HDMI 1.4. The LG D2341P is a 23-inch Full HD 3D monitor, the LG D2242P is 21.5-inch Full HD 3D monitor, the LG D2342P is 23-inch Full HD 3D monitor and the LG D2542P is 25-inch Full HD 3D monitor. All of them use TN panels with LED backlight, meaning more affordable price, have 5ms response time, 1000:1 contrast ratio (5 million to 1 dynamic) and provide up to 250 cd/m2 maximum brightness in 2D mode and 100 cd/m2 in 3D mode. The LG Cinema 3D monitors will be launched in Korea today and will be rolled out globally early June starting in Europe.

All four new models from the D41P and D42P series will be bundled with DDD’s TriDef 3D software that will be ensuring the stereoscopic 3D support for games, as well as 3D video playback and the 2D to 3D video conversion functionality. The TriDef software is universal, meaning it will work with both AMD/ATI and Nvidia-based GPUs and the models with HDMI 1.4 interface should be compatible with consumer 3D electronics such as PS3 consoles or Blu-ray 3D players. Have in mind that these monitors are not compatible with either 3D Vision or the 3DTV Play software from Nvidia and will not be made compatible in the future as well.

The main advantage of the use of passive polarizing filters is that it brings down the cost of the display and makes the glasses much more affordable as they do not need any electronics, just two plastic filters with different light polarization. The drawbacks are mostly the limited vertical resolution (the halved number of horizontal lines per eye), as each eye perceives only 1920×540 pixels, something that could bring some issues with distinguishing finer details and small text in 3D, as well as the significantly limited vertical viewing angle of the display when in 3D mode as compared to the angle in 2D.

LG R590 3D Notebook With Passive Polarization 3D Technology

July 21st, 2010 · 2 Comments · General 3D News

It seems that LG is not only interested in 3D HDTV market as well as 3D Gaming monitors, but also in providing a mobile 3D-capable solutions and as a result the company announced their first such product – the LG R590 3D notebook. The 3D laptop has a 15.6-inch screen with resolution of 1366×768 pixels and uses a passive polarization filter along with passive polarized glasses to provide the 3D effect. The software LG is relying to provide the 3D capabilities is DDD’s TriDef giving the user a 3D photo and video player, 2D to 3D video conversion and the option of gaming in stereo 3D mode. As with other such passive polarized solutions you should be aware of the fact that the vertical resolution is being halved when in 3D mode meaning that you get just 384 pixels per eye which can be an issue sometimes as it makes harder to read small text etc., so it is not the perfect solution as it also goes with more limited viewing angles and other typical issues for products using the passive polarization technology from other manufactures like Acer for example.

The laptop can be equipped with a fast mobile quad core Intel Core i7 processor, using HM55 chipset and Nvidia GeForce GT335M video card (72 stream processors) along with 1GB of GDDR3 video memory (128-bit memory bus) which makes the system quite capable in providing quite comfortable experience when you play most not so demanding games in stereo 3D mode with the available lower resolution display. But I will not be surprised if in a few moths time LG decides to switch to a 120Hz LCD panel and 3D Vision shutter glasses and/or maybe if there are alternative solutions using active shutter glasses by that time. The LG R590 3D notebook is expected to be available on the market around the middle of August, but there is no information yet about what will be its price.
