Samsung Electronics develops Bright 4-inch Wide-Screen LCD for Portable Media Players
Samsung Electronics just announced that it has developed a new 4-inch screen digital interface LCD with a 16:9 screen ratio exclusively for Portable Media Players (PMP).
PMP is a next-generation multimedia player that can play video images downloaded from the Internet at any time, any where in a convenient format. Market anticipation for a full-scale portable video player has increased dramatically in recent months. PMP's expanded capacity allows for a variety of media player features, including music and video.
The screen is a 4-inch LCD with a 16:9 ratio and is made specifically for the PMP market. The LCD panel used for existing PMPs is generally 3.5 inches and has a 4:3 ratio. When a 16:9 Digital Internet Video eXpress (Divx) file is played in the current format, the screen is not fully utilized, particularly at the top and bottom of the screen. In addition, its 8-bit digital interface allows for 16.7 million-color video images, and its 50 percent color gamut offers a clear and crisp image display.
According to Samsung, research into the most appropriate screen size has found that 4-inch screens are the most efficient. A 3-inch screen is hard to view due to its small screen size; a 5-inch screen is too large to fit into a pocket.
Considering that many consumers use PMPs outdoors, the brightness has been enhanced from 150cd--the general brightness of mobile handsets--to 180cd. Visibility has also been enhanced through TMR (Transmissive with Micro Reflective) mode, which reduces the reflection of sunlight.
