On October 17, 2007, Samsung Electronics Co., Ltd., (SEC) announced the development of new LCDs for notebook PCs. Two offers a 16:9 aspect ratio, just like a HD TV, and the third features an active white LED backlight that increases picture clarity and reduces power consumption. SEC will unveil these LCDs at FPD International being held in Yokohama, Japan, October 24-26. Mass production is scheduled to commence in 1H’08 for the 16:9 LCDs and in 2H’08 for the white LED backlight LCD. I’m not as excited about the 16:9 LCDs as I am with the “active” LED backlight panel, but it is quite a long ways from now, unfortunately.

The two 16:9 LCDs are 16″ and 18.4″ in size. The color gamut is 60% for the 16″ and 90% for the 18.4″. Quite high considering typical notebooks have about 45% NTSC. Since these two are using CCFL backlights, I will assume that the phosphors have been improved to generate an improved color gamut. The wide color gamut CCFL (WCG-CCFL) can be nice for general movie watching but color matching can be a problem for those serious about color. Contrast ratio for the 16:9 panels is a pretty good 800:1 but the response time isn’t going to be fast enough (8ms) to replace your TV for video viewing. The number of colors (262,144) tell you that these are 6-bit panels. It seems the 18.4″ will have a pixel format of 1920 x 1080 (Full HD, 1080p). I have a 17″ Dell with a pixel format of 1920 x 1200 and it is pretty large. I wonder if consumers will buy into a 18.4″ notebook PC. It might be just a tad bit too big in my opinion. Of course, if it was slimmer, lighter, sexier and lasted many more hours, I wouldn’t mind the extra 1.4″. But please don’t put the keyboard to the left since I have no use for a numeric keypad. By the way, the 1366 x 768 pixel format for a large 16.0″ LCD sounds a bit on the low side.

SEC’s 15.4″ active white LED backlight LCD sounds pretty cool as the company states that it will consume 40% less power than a typical LED backlight. That would mean that it will consume even less than a typical CCFL backlight. I certainly appreciate the improvements in backlight technology as it seems the battery industry is not going to be providing much useful advances soon with batteries exploding and even battery factories catching on fire. The active part of the LED backlight involves illuminated areas of the display with varying degrees of brightness. To make dark areas dark the LEDs for that portion of the display are turned off. When dark becomes more dark and bright areas become more bright, contrast ratio is improved and SEC states that the contrast ratio is 10,000:1. Wow. But other features are just normal: viewing angle (120/120), color gamut (45%) and brightness (300 cd/m2).
