I was just going over the specs for the new 32" Samsung LTN325W LCD panel and found that it has a response time of just 16ms. That is considerably better than any LCD panel over 20" that I have seen.

Previous response time for the LTM295W was 22ms.

It appears as though the contrast ratio for the LTN325W may be 600:1 rather than the 500:1 listed above because the following press release says that Samsung's Digital Natural Image Engine is applied to both the 32" and 40" model to provide the 600:1 CR and a 500 cd/m2 brightness level.

Actually, these TV's use a new technology from Samsung that they developed especially for large screen LCDs. I can't recall the name off the top of my head, but it significantly:


1) Reduces the full response times.

2) Reduces the in-between response times.


"In between response times? What the heck are those?" ... at least that's what I said to the Samsung Lead Engineer. Well it goes something like this. Response times actually measure the Rise (Go to White) and Fall (Go to Black). What they don't measure, are going to,say, green (or any non-full white color). A non-white signal actually requires the LCD to send a non-full electrical signal to the pixel. Generally, this results in a slower rise time as it is a weaker signal to respond to. Since a significant portion of a moving picture isn't white, the rise time for non-white colors becomes very important. Unfortunately, the industry does not measure this response and that's why there is SUCH a blurring discrepancy between two LCD displays with, say, the identical 25MS response times.


Enter Samsung technology. Non-white electronic signals are actually sent at FULL strength for a brief moment and than immediately to the correct strength, thereby causing the pixel to respond at it's fastest possible speed.


Now if I could only convince them to implement this in a Computer LCD Display ... Battlefield 1942 Heaven =)

Although the LTN 325W has "only" 768 lines it does qualify as a computer LCD display as it has a DVI input for the PC.


I've found a press release for another Samsung LCD panel with an even better response time. It is a 54 inch LCD with 1920 x 1080 resolution and response time of less than 12msec

From what I've read a long time ago, they are planning to break the single digit barrier in about a year or two.


Hey, Slivers... do you mean PVA (Pattern Vertical Alignment) technology?
