EK73510Z004A  Gate COF Overview

Gate COF is a key section of the TFT panel driving system that controls the row-by-row scanning of the display. It generates and distributes gate signals in a proper sequence so each line of pixels can be activated accurately during image formation. This section works closely with driving voltages like VGH and VGL to ensure correct ON and OFF switching of TFT cells. In simple terms, Gate COF manages the vertical scanning process of the panel and plays an important role in stable and clear picture output. If there is any issue in this area, the panel may show no display, vertical lines, or improper scanning behavior on the screen.

Technical Experience Note

We have published this COF data as a reference guide for technicians working on panel repair. My advice for technicians is to always handle the panel with extreme care while doing any bypass work. In many cases, VGH and VGL lines become shorted, so if you are bypassing them, make sure to cut from both sides properly — from the glass side as well as from the COF side. This helps to completely isolate any internal glass short and prevents future issues. After proper cutting, use jumper wires for bypass instead of simple single-side repair, so the panel can perform in a more stable and long-lasting way.

EK73510Z004A COF Pin Description

• 1. VGH = 24.8V
• High Voltage Gate Description. This is the voltage that needs to be applied to the positive gate drive to turn on the TFT transistors. Usually kept between +20V and +30V to keep the panel working properly.
• VGL = -5.8V
• Gate Low Voltage, to put it simply. The TFT gates are fully turned off using this negative bias, which stops undesired leakage currents.
• VDD = 3.3V
• Description: The voltage that powers the logic. Gives the COF driver IC and internal logic circuits a steady supply of power.
• GND = 0V
• Level of ground reference. This point is used as a reference for all voltage and signal measurements.
• STV = 0.02V
• Start Vertical (Start Pulse) is the name of the description. This control signal starts the vertical scanning sequence in the gate driver.
• CPV = 0.8V (Pulse)
• Clock Pulse Vertical is the description. serves as the gate driver’s vertical shift clock, allowing for sequential line scanning across the screen.
• OE = 2.3V (Pulse)
• Description: Enable output. decides whether pixel data stays in the hold state or is latched and moved to the panel.
• XAO = 3.2V
• Description: An auxiliary enable signal that is frequently connected to reset functionality or IC power sequencing (often connected to Power-On Reset circuits).
• UD = 0V
• Up/Down Control is the description. specifies the gate driver’s scanning direction, which can be either top-to-bottom or bottom-to-top based on the panel configuration.
• STVR = 0.02V
• Overview: Secondary Start In order to synchronize vertical scanning, the opposite side gate driver usually uses a vertical signal.
• VCOM = 6.2V
• Common Voltage is the description. minimizes distortion, minimizes flicker, and stabilizes image rendering by providing a DC bias reference across the LCD panel.
