What Are G61 G578 LCD Components?
G61 and G578 are crucial gate driver output pins in high-channel TFT LCD gate ICs, such as ILI5960 or OTD9960A. They deliver precise high-voltage pulses row-by-row, enabling accurate pixel control for large industrial, automotive, and medical displays. These pins allow scalable, reliable performance, making them essential in custom LCD modules from brands like Gesight, which specialize in high-brightness and ruggedized solutions.
What Is a G61 G578 Gate Driver?
G61 and G578 are output pins on 960-channel TFT LCD gate drivers, shifting scan signals sequentially to activate display rows. Gate drivers like ILI5960 power TFT panels in industrial, medical, and automotive settings. They feature high-voltage CMOS operation up to 40V and support bi-directional scanning through the RL pin. Gesight integrates these drivers in custom BOE and AUO modules, enhancing performance with EMI optimization and touch capabilities.
| Pin | Channel Position | Function |
|---|---|---|
| G61 | Early mid-sequence | Outputs high-voltage pulses for row activation |
| G578 | Late mid-sequence | Shifts scan to subsequent rows |
| G1 | First row | Start of scan sequence |
| G960 | Last row | End of scan |
How Does G61 G578 Work in LCD Panels?
These pins operate by shifting high-voltage pulses via CPV clocks after the start pulse (STVR), sequentially activating TFT gates. The process begins with the start pulse triggering the shift register, moving VGH signals from G1 through G61, G578, to G960. Output Enable (OE) controls activation, and MODE pins configure channel counts. Gesight combines these drivers with LVDS or MIPI interfaces, high-brightness up to 3000 nits, optical bonding, and ruggedized touch for industrial-grade displays.
What Are Key Features of G61 G578 Drivers?
G61 and G578 support 960-channel outputs, bi-directional shifting, 40V drive, 2.7–3.6V logic, cascading for expansion, and CMOS COG packaging. They excel in double-gate control, shift up/down selection, and high-frequency operation (up to 200kHz), ideal for large automotive dashboards, medical monitors, and industrial panels. Gesight integrates these drivers into custom TFT/IPS modules with capacitive touch and full environmental testing for global markets.
Which Panels Use G61 G578 Gate Drivers?
These drivers are commonly found in large TFT LCD panels ranging from 14 to 55+ inches for industrial, automotive, and medical applications. High-resolution screens, such as 1920×1080 automotive displays or industrial COG modules, rely on many gate lines. Gesight sources panels from BOE, AUO, Sharp, LG, JDI, and Tianma, producing scalable solutions with a daily capacity of 10,000 units for global distribution.
Why Choose G61 G578 for Custom Displays?
Using G61 and G578 offers high channel count, reliability, and flexibility for large-panel designs. They reduce the number of required ICs and enable cost-effective scaling. Rugged features suit harsh environments, while cascade support allows ultra-high-resolution configurations. Gesight optimizes firmware and EMI performance for these drivers, ensuring dependable custom LCD solutions.
How to Integrate G61 G578 in Designs?
Integration involves connecting VGH/VEE to power, CPV/STVR to the timing controller, RL for direction control, and cascading STV pins for larger panels. Proper voltage management (VGH 15–20V, VDD 3.3V) is essential. Gesight provides full engineering support, from controller board design to testing, ensuring compatibility with HDMI, eDP, and MIPI interfaces, high nits, and wide viewing angles.
What Are Common Applications for G61 G578?
These pins are widely used in:
