5.1 Display Characteristics
M190MWW3
The M190MWW3 is a color active matrix thin film transistor (TFT) liquid crystal display (LCD) that uses amorphous
silicon TFT as a switching device. It is composed of a TFT LCD panel, a timing controller, voltage reference,
common voltage, driver DC-DC converter, column driver, and row driver circuit. This TFT LCD has a 19-inch
diagonally measured active display area with WXGA+ resolution (1440 vertical by 900 horizontal pixel array).
TPM190A1
TPM190A1(M190A1-P0A) is a 19” wide TFT Liquid Crystal Display module with 4 CCFL Backlight unit and 30 pins
2ch-LVDS interface. This module supports 1440 x 900 WXGA+ mode and can display 16.7M colors. The front metal
frame for backlight is not built in, and need monitor front plastic bezel instead.

5.3 Electrical Characteristics
1.TFT LCD Module:
M190MWW3
Note:
A. If it exceeds MIN/MAX values, then "CCFL Life", "ON/OFF Cycle", and "SAFETY" will not be guaranteed.
B. CCFL Frequency should be carefully determined to avoid interference between inverter and TFT LCD.
C. The voltage over specified value (VCCFLi) should be applied to the lamp more than 1 second after startup.
Otherwise, the lamp may not be turned on. The used lamp current is the lamp typical current. The inverter should be
able to give out a power that has a generating capacity of over 1560 voltage. Lamp units need to over 1560 voltage
for ignition.

10. White- Balance, Luminance Adjustment
Approximately 30 minutes should be allowed for warm up before proceeding white balance adjustment.
Before started adjust white balance , please set the Chroma-7120 MEM Channel 3 to Warm (6500K) color, MEM
Channel 4 to Normal (7300K) color, MEM Channel 9 to Cool (9300K) color , and MEM Channel 10 to sRGB color
2
( our Warm color parameter is x = 283 ±30, y = 297 ±30, Y=180cd/m
2
317 ±30, Y=190cd/m
; Cool color parameter is x = 313 ±30, y = 329 ±30, Y = 200 cd/m2; sRGB color parameter
