DisplaySearch reveals top panel development trends

DisplaySearch revealed the top panel development trends in its latest "Large Area TFT LCD Product Plan Report". Cost effective design, power savings and green initiatives, along with the 16:9 aspect ratio for notebook and LCD monitor panels are the leading trends for 2009. The report analyses product and technology roadmaps of each panel supplier in four major applications in 10" and above sizes: Notebooks, LCD monitor, Industrial, and LCD TVs.

DisplaySearch's research indicates that some delays in LED products in the notebook application were due to LED standardisation on 16:10 notebook panels this year, but panel makers used LEDs in more than 90% of 16:9 notebook panels. When panel makers develop 16:9 notebook panels, they design the LED backlight at the same time. Therefore, notebook brand makers will migrate to LED quickly when launching their new 16:9 notebook products. Some panel makers also announced their notebook panels will all use LED backlights after 2010. In addition, notebook panel makers did not increase their brightness on mainstream models, but focused on the weight and power consumption for future plans.

Environmental responsibility and lower power consumption have become primary design concepts for LCD monitor panels. By reducing the number of lamps from four to two, total panel power consumption is reduced by 30-40%. However, there is a trade-off between power consumption and brightness. Models with two lamps can only reach 250 to 270 nits, using prism films and a two-diffuser design. If LCD monitor panels need to maintain 300 nits, panel makers need to add another DBEF (Dual Brightness Enhancement Film). Therefore, costs actually increase if the brightness is held to 300 nits while the number of lamps is reduced.

In LCD TV panels, most suppliers segment models into different categories of specifications to cope with the price trends. Entry-level models typically offer brightness of 400 to 450 nits and a 2000:1 contrast ratio. In mainstream HD models, brightness is typically 450 to 500 nits and contrast ratio is in the range of 2500:1 to 3000:1. For premium models over 37", the brightness is 500 nits, and the contrast ratio is upgraded to 5000:1. In addition, DisplaySearch found that panel makers only implemented 120 Hz with 10 bits on full HD models from 2H'08. LED backlights were only used in sizes of 42" and above. LCD panel makers also used FMB (front mount bezel) to reduce the mechanical cost and provide a slim design for LCD TVs. Green products and power-saving improvements were found in LCD TV panels, including power consumption reduced by 30-40% in roadmaps for 26" to 42".

The Q3'08 Large Area TFT LCD Product Plan Report is the only report in the TFT LCD industry to analyse product roadmaps, technology blueprints and new materials, as well as large-area TFT LCD specifications. The 252-slide report covers the following topics:

* TFT LCD panel makers' latest product strategies and technology plans for the three main large-area applications: notebook PCs, LCD monitors and LCD TVs

* Notebook PC, LCD monitor and LCD TV brand makers' product strategies, covering 20 notebook PC brands, 40 LCD monitor brands and 70 LCD TV brands

* A matrix of panel product size, economic panel sizes, and fabs for 15 large-area TFT LCD makers and over 50 TFT LCD fabs

* Industrial panel design trends from panel makers
