TFT-LCD panel reproduces colours in high resolution

Samsung Electronics Co. Ltd announced that it has developed an amorphous silicon, 7-inch, single-chip TFT-LCD panel that reproduces colours in high resolution (WVGA-level, 800 x 480 pixels).

Seven-inch LCDs are mostly used in mobile devices including digital multimedia broadcasting, portable multimedia players and car navigation systems, and normally require four to seven drive ICs. On a conventional 7-inch LCD panel, the T-con (time controller that drives the screen), power platform and other components typically are attached to a circuit board on the exterior of the LCD. The complexity of this integration point is said to have been a major obstacle to slimming the package profile of mobile LCD devices.

This single-chip design, with a contrast ratio of 400:1 and a brightness level of 450 nits, uses Samsung's amorphous silicon gate technology. This technology incorporates the gate-driver IC function directly on the surface of the glass panel, while simultaneously integrating the T-con within the drive-IC. In the single-chip design, the surface area of the drive circuit and the number of components that it contains are each one-third less than that used in existing WVGA panel designs.
