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.

REMARK:
1) MCU initialize.
2) Is the EPROM blank?
3) Program the EPROM by default values.
4) Get the PWM value of brightness from EPROM.
5) Is the power key pressed?
6) Clear all global flags.
7) Are the AUTO and SELECT keys pressed?
8) Enter factory mode.
9) Save the power key status into EPROM.Turn on the LED and set it to green color.Scalar initializes.
10) In standby mode?
11) Update the lifetime of back light.
12) Check the analog port, are there any signals coming?
13) Does the scalar send out an interrupt request?
14) Wake up the scalar.
15) Are there any signals coming from analog port?
16) Display "No connection Check Signal Cable" message. And go into standby mode after the message
disappear.
17) Program the scalar to be able to show the coming mode.
18) Process the OSD display.
19) Read the keyboard. Is the power key pressed?
