Scope
M121-55HBA is a TFT LCD color module to be designed to realize the largest screen on A4 size notebook
style personal computer, PC monitor and industry application. In addition to its large screen, the
characteristics of this module are high luminance, light weight, slim/thin outline, low power consumption and
high resolution of SVGA (800x600) capability.
Features Application
. 30.8cm(12.1 inch) diagonal . Notebook PCs
. Native 262k colors (R/G/B 6 bit each) . Monitors
. SVGA 800 x 600 pixels
. Low Reflection (Black Matrix)
. Two lamps backlight

. 360 cd/m high luminance
. 278mm x 205mm x 13mm typ.
(Need min. 3mm clearance from lamp cables)
. 475 g typ.
. 8.29 W typ.
Notes
. The construction of M121-55HBA is to add a TTL RGB to LVDS (SN85LVDS84A) conversion
card to M121-55DB (LVDS input) TFT LCD Module.
This module does not contain an inverter card for backlight.
The LCD cell is supplied from IBM.
