Cost-effective design, power savings including green solutions, and 16:9 aspect ratio panels for notebook PCs and LCD monitors are the three major development trends in 2009, according to DisplaySearch's latest Q1 09 Large Area TFT LCD Product Roadmap Report. The research firm also reported that these three features are often combined in many new notebook and LCD monitor panels. For LCD TV panels, better image quality such as 120Hz or 240Hz frame rates and power-saving technologies are the major development directions.

The Q1 09 Large Area TFT LCD Product Roadmap Report indicated the following important trends in panel makers' product and technology roadmaps:

??Korean panel makers are combining double frame rate (100Hz/120Hz) with edge-type LED backlights to achieve power saving and better picture performance while limiting the added cost. Samsung's 40-, 46-, 52- and 55-inch wide, and LG Display's 32-, 37-, 42-, 47- and 55-inch wide are all examples of this trend. Taiwan panel makers AUO and CMO are following suit.
??Panel makers think monitor panels are moving to 16:9 formats, including 15.0-, 15.6-, 18.4-, 21.6-, 24- and 27-inch wide Full HD. Gen 6 or larger fabs were originally designed for making TV panels, so they have an advantage for these panel sizes.
??Samsung will produce 18.5-inch wide and 21.5-inch wide 16:9 monitor panels on its Gen 8 line from Q1 09, and 20-inch wide will be produced in Gen 7. 18.5-inch wide panels can be cut 50-up from a Gen 8 substrate; 21.5-inch wide is 35 cut on Gen 8.
??To deal with monitor panels moving to 16:9 and Gen 6 production, all three Gen 5 owners in China (SVA NEC, BOE and InfoVision) are aggressively developing 16:9 notebook PC panels including 13.3-, 14.0- and 15.6-inch wide, and 10.1-inch wide for mini-note PCs.
??With the introduction of gate in panel or so-called gateless technology for TFT LCDs, panel makers can remove gate driver ICs to reduce cost, as well as the border around the displayenabling Samsung to reach 18-up panelization of 16-inch wide notebook panels on its Gen 5.
??Following TMD Display and HannStar, panel makers like Samsung, AUO, LG Display, CMO, CPT, BOE and InfoVision are developing 11.6-inch wide 16:9 notebook panels.
??More panel makers will introduce LED backlights in monitor panels during 2009. Taiwan and Korean panel makers are rapidly adopting LED backlights in 16:9 monitor panels. Samsung, LG Display and CMO will introduce RGB LED backlights for high-end models.
??Following Samsung, LG Display, AUO, CMO and CPT are all developing 20-inch wide HD+ (1,600pixels x 900pixels) monitor panels. This format is gradually replacing 19-inch wide panels for monitors. Meanwhile, to achieve power savings, such panels use two CCFLs rather than four.
??Samsung continued to be the only notebook panel maker to develop 13.4-inch wide 16:9 panels, as LG Display, CPT, AUO, CMO, BOE and InfoVision all chose 13.3-inch wide 16:9 as the main size for the 13-inch notebook segment. Meanwhile, Samsung and LG Display are developing 17.3-inch wide 16:9 panels aimed at desktop replacement notebook PCs.
??Panel makers are increasingly developing LED backlight monitor panels, including AUO, CMO, CPT and Innolux at 18.5-inch; AUO, CPT and Innolux at 21.5-inch wide; LG Display and CMO at 22-inch wide; Samsung and Innolux at 23-inch wide; Samsung and LG Display at 24-inch wide; and AUO and CMO at 23.6-inch wide.
