Side COF Data Connection & Test Point with Scalar Strip
V420HJ1-XRP01 Side COF and Scalar Test Points The COF data number of this panel is nt39565h-c5253a. This specific COF number is used with different panels, and I also have the scalar strip data of each panel in a single photo, so I am publishing it with the panel title. In this article, you will also find an image of this COF data in original 4k resolution, the PDF link of which I will put at the end. You can download it for free.

| Pin # | Signal / Function | Description | Test Point / Note |
|---|---|---|---|
| 1 | VGH | This voltage is used to keep the TFT gate drive in a high state, in simple terms, these voltages turn on the gate drive. | Expected: +27V |
| 2 | VGL | These voltages are used to keep the TFT in a low state, meaning these negative voltages turn off the TFT. | Expected: -7.8V |
| 3 | VDD | This power supply operates the logic circuit for the source COF and also for the internal panel. | Typical: +3.3V |
| 4 | GND | This is ground. It works everywhere in the panel’s internal circuit, including the scalar strip. | ~0V |
| 5 | STV | The function of the STV is that it generates clock pulses, which is where the scanning process begins. | 0.04V |
| 6 | CKV | CKV is a clock signal that causes the gate drive to shift the line, which is why double image faults are seen in some panels. | +1.71V |
| 7 | OE2 | OE2 This signal enables and controls the output of display data. | +1.36V |
| 8 | OE1 | OE1 This controls the secondary signal output. | +1.36V |
| U | UD | UD Its function is to control up-down scanning and it also identifies the direction of vertical scanning. | 3.3V |
| L | LR | Its function is to control the left-right horizontal shaft. | +3.3V |
| R | STVR | The STVR starts the backup line and this is the secondary start pulse signal. | 0.06V |
| V | V-COM | Common voltage flicker and screen black level setting | +7.3V |
