Where Is the LCD Panel Model Number?
In most cases, the LCD panel model number is printed on a manufacturer label attached to the rear chassis, frame, or housing. It may also appear on a smaller label near the signal connector or be printed directly on the panel structure.
- Check the main white label on the rear metal cover.
- Look near the signal connector for a second manufacturer label.
- Check the equipment parts list, service manual, or previous purchase record.
- If the label is hidden, follow the equipment service instructions before removing the panel.
Disconnect the equipment from power, protect exposed electronics from static discharge, and avoid pulling or folding display cables. Ask a qualified technician for help when the panel cannot be removed safely.
How to Identify the Complete Model Number
A panel label can contain several codes. Start by identifying the panel manufacturer, then inspect the label for a structured alphanumeric code that may be marked Model, Model No., P/N, or Part No. Common model formats include:
LM201U05-SLB1B133EW03 V.2AT080TN03 V.2G150XG01 V3NL6448BC33-64
Record the code exactly as printed. Do not omit prefixes, leading zeros, hyphenated suffixes, version numbers, or revision letters. For example, B133EW03 V.2 should not be shortened to B133EW03 when requesting a replacement.
Model Number, Part Number, and Serial Number
| Label information | What it identifies | Useful for replacement? |
|---|---|---|
| Model number | The LCD panel model or version | Yes — primary identifier |
| Revision/version | A specific panel revision | Yes — keep it with the model |
| Serial number | One individual manufactured panel | Usually no |
| Customer part number | A number assigned by the equipment manufacturer | Sometimes |
| Production code | Factory, date, or batch information | Usually not by itself |
| Board or cable number | A T-CON board, driver board, or cable | Not as the panel model |
The primary panel identifier may be marked Model, Model No., P/N, or Part No. An equipment manufacturer's internal part number is a separate identifier, so use the surrounding manufacturer and label information rather than the field name alone.
If two codes both look like possible model numbers, photograph the complete label instead of guessing. A number printed on a circuit board is not necessarily the LCD panel model.
When comparing an original label with a supplier reference, use the LCD Panel Model Matching Guide to classify the result as an exact match, unconfirmed, or not exact.
Identifying the original panel's complete model number is only the first step. Before using a different model as a replacement, verify its interface, voltage, pin assignment, backlight, dimensions, and mounting details.
Take Photos That Can Be Used for Model Matching
Clear, complete photos provide more evidence than a manually typed partial code. Photograph:
- The complete rear side of the LCD panel
- The entire main label
- A close-up in which every character is readable
- Additional labels and printed markings
- The signal connector and cable
- The equipment nameplate, if available
Use sufficient light, hold the camera parallel to the label, avoid glare, and do not crop off either end of a number. Send the original-resolution images when possible.
Common LCD Model Number Mistakes
Searching with an incomplete model
A base model without its suffix or revision may return panels from the same series that are not the same version.
Using the equipment model
The number on a monitor, HMI, medical device, or machine identifies the complete equipment, not necessarily its installed LCD panel.
Using a board or cable number
Codes on the T-CON board, inverter, backlight board, or signal cable may identify only that component.
Assuming similar model numbers are interchangeable
A suffix change can represent differences in interface, voltage, pin assignment, backlight, dimensions, mounting, or operating characteristics.
Relying only on screen size
Panels with the same diagonal size and resolution can still be electrically or mechanically incompatible.

Frequently Asked Questions
Can I find the model without removing the screen?
Sometimes. It may be listed in a service manual, parts list, maintenance record, or previous invoice. However, equipment from the same series can use different panels, so the installed panel label is normally stronger evidence.
Is the number below the barcode the model number?
Not always. It may be a model number, serial number, customer part number, or production code. Check the manufacturer name and surrounding label text before using it.
Can I search using only part of the model number?
A partial code can help locate a product family, but it is not enough to confirm an exact replacement. Use the complete model, suffix, and revision whenever available.
Is the equipment model enough?
Usually not. The same equipment model may have been produced with different LCD panels. Provide both the equipment model and photos of the original panel label.
What if the label is missing or unreadable?
Send photos of the complete panel, rear chassis or frame, circuit boards, connectors, cables, and equipment nameplate. These details may narrow the possibilities, but appearance alone often cannot confirm an exact model.
