G190EG02 V1 Functional Block Diagram
The following diagram shows the functional block of the G190EG02 V1 Color TFT-LCD Module:
The G190EG02 V1 functional block diagram shows its main signal and power flow. The panel receives external input via the LVDS interface and is powered by a +5V supply. LVDS signals are first processed by the LVDS receiver, then sent to the timing controller and RSDS transmitter to ensure correct TFT-LCD pixel refresh.
Inside the panel, a DC/DC converter handles voltage conversion and level adjustment. A Gamma correction circuit optimizes image brightness and color. For backlight, the G190EG02 V1 uses an LED system powered by an external LED driver, which provides DC power and drive signals. Control signals pass through the panel’s ASIC chip to the X-Driver IC for precise pixel control. Backlight brightness and drive power are managed by Gamma correction and the DC/DC converter, keeping the display stable under high brightness and low power conditions.
G190EG02 V1 Applications
The G190EG02 V1 offers high stability, wide viewing angles, and steady brightness. It fits many uses, such as industrial control, medical devices, POS/ATM terminals, and security monitors. In all these applications, it delivers a clear and stable display.

It fits patient monitors, lab analysis devices, and nurse workstations. The stable LED backlight helps medical staff get information quickly and correctly.
3. POS / ATM terminals
POS and ATM systems must handle long working hours, frequent use, and different lighting conditions. The G190EG02 V1 can show more transaction information and improve the user experience. Its wide viewing angle and even brightness make the screen easy to read at the counter or in outdoor ATM machines.
4. Surveillance and security systems
In monitoring centers or security systems, screens must run for long hours and keep stable image quality. The LED backlight and uniform brightness of the G190EG02 V1 ensure smooth video display. It is suitable for security walls, traffic monitoring, and building security displays. It can show important details such as plates, human shapes, and motion.
Handling Precautions
1. Avoid scratching the front polarizer; it is easily damaged.
2. Turn off the power before connecting or disconnecting the input.
3. Wipe off water immediately to prevent spots or discoloration.
4. Clean the panel with soft cloth or absorbent cotton.
5. Handle carefully; glass panel may break if dropped or bumped.
6. Prevent static discharge; ground yourself when handling CMOS LSI.
7. Do not open or modify the module.
8. Avoid pressing the reflector sheet at the back.
9. When returning the module to its slot, press gently at LED light bar ends, not the center.
10. Do not rotate or tilt the signal interface connector during insertion/removal.
11. Do not twist or bend the module after installation; design enclosure to avoid stress.
12. LCD uses limited non-flammable materials; use power supply per Limited Power Source standards (IEC60950/UL1950).
