G190ETN01.4 Electrical Interface and System Integration
The G190ETN01.4 uses an industrial-standard electrical interface design, ensuring stable data transmission while simplifying integration with various industrial control systems. It is suitable for embedded devices and industrial display terminals.
1. Interface and Electrical Features
Dual-channel LVDS (30-pin) interface: The panel features a 30-pin dual-channel LVDS interface, supporting SXGA (1280 × 1024) resolution and 8-bit color depth (16.7M colors). The dual-channel design balances data bandwidth, maintaining smooth and flicker-free images even at higher refresh rates.
5V typical input voltage: The logic driver operates at a typical voltage of 5.0V, compatible with most industrial motherboard power standards, reducing the need for additional voltage conversion circuits.
Easy embedded system integration: Compliant with industrial interface standards, the G190ETN01.4 can connect directly to mainstream industrial motherboards such as Mini-ITX, 3.5" SBCs, or embedded systems based on ARM or x86 architectures.
2. Advantages of LVDS in Industrial Displays
Strong EMI resistance: LVDS uses differential signal transmission, which significantly reduces electromagnetic radiation and effectively resists common-mode noise in industrial environments.
Low-power transmission: Compared to traditional TTL interfaces, LVDS maintains high-speed data transmission while consuming less power, making it ideal for long-term operation in industrial equipment.
Stable long-distance transmission: LVDS signals remain stable over long cable runs, suitable for applications where the control board and display are separated, such as industrial cabinets, automation equipment, or ATM terminals.

Handling Precautions
1) Since front polarizer is easily damaged, please be cautious and not to scratch it.
2) Be sure to turn off power supply when inserting or disconnecting from input connector.
3) Wipe off water drop immediately. Long contact with water may cause discoloration or spots.
4) When the panel surface is soiled, wipe it with absorbent cotton or soft cloth.
5) Since the panel is made of glass, it may be broken or cracked if dropped or bumped on hard surface.
6) To avoid ESD (Electro Static Discharde) damage, be sure to ground yourself before handlingTFT-LCD Module.
7) Do not open nor modify the module assembly.
8) Do not press the reflector sheet at the back of the module to any direction.
9) When placing a module back into the container, do not press the center of the LED light bar edge. Press both ends gently to avoid damage.
10) When inserting or removing the signal interface connector, do not rotate or tilt the connector.
11) Do not twist or bend the TFT-LCD module. Ensure the product design prevents external force from end users.
12) Some materials in the module are non-flammable rated. The power supply must comply with Limited Power Source (IEC60950-1 / UL60950-1) or equivalent exemption.
13) High-temperature continuous operation may accelerate lamp aging and reduce brightness.
14) Displaying a fixed image for long periods may cause image sticking. Use a screen saver or change content periodically.
