What Is an Exact LCD Panel Model Match?
Two references are an exact model match only when they identify the same LCD panel manufacturer and the same complete model designation assigned by the manufacturer. Compare every character, including the suffix and revision.
| Field | What must match | Example |
|---|---|---|
| Manufacturer | The original panel manufacturer | AUO |
| Base model | Every letter and number | G150XG01 |
| Suffix | Any suffix included in the manufacturer's complete model designation | -SLB1 |
| Revision/version | The complete revision marker | V3 or Rev.C1 |
A one-character difference, missing suffix, or different revision prevents an exact-match confirmation until authoritative documentation proves the references are simply alternate presentations of the same complete model.

How to Match an LCD Panel Model
- Identify the source. Confirm that both codes refer to the LCD panel itself, not the equipment, circuit board, cable, or inverter.
- Confirm the manufacturer. The same-looking code from a different manufacturer should not be treated as the same model without documented cross-reference evidence.
- Copy both codes exactly. Preserve leading zeros, spaces, hyphens, parentheses, suffixes, and revision markers.
- Compare character by character. Check easily confused characters such as
0/O,1/I,5/S, and8/B. - Verify the suffix and revision. Do not stop after the shared base model.
- Classify the result. Record it as confirmed exact, incomplete/unconfirmed, or not an exact match.
Three Possible Results
LCD Model Matching Examples
| Original reference | Compared reference | Result | Reason |
|---|---|---|---|
B133EW03 V.2 | B133EW03 V.2 | Exact match | Complete code and revision match |
B133EW03 V.2 | B133EW03 | Unconfirmed | The compared reference omits the revision |
B133EW03 V.2 | B133EW03 V.3 | Not exact | The revision differs |
LM201U05-SLB1 | LM201U05-SLA1 | Not exact | One suffix character differs |
NL6448BC33-64 | NL6448BC33-64 | Unconfirmed | The code matches, but the manufacturer of the second reference is unknown |
A “not exact” result does not automatically mean the panels are incompatible. It only means they are not the same complete model reference.
If only the revision differs, read Can Different Revisions of the Same LCD Panel Model Be Interchangeable? before treating either revision as a replacement.
Which Evidence Should You Use?
Use the strongest available evidence and retain the original images or documents used for the decision.
Original panel label
Usually the strongest starting point when the manufacturer and complete code are readable.
Manufacturer datasheet
Useful for confirming the official model designation, suffix, and panel revisions covered by the document. Do not confuse the datasheet's document revision with the panel revision.
Equipment parts list
Useful when it explicitly maps an equipment part number to a complete panel model.
Previous order record
Supporting evidence only; verify that it records the complete model actually supplied.
Search listings, handwritten notes, and manually typed codes can contain omissions or transcription errors. Verify them against a label or authoritative document before confirming a match.
Common Model Matching Mistakes
Comparing only the base model
Matching characters at the beginning do not confirm the suffix or revision.
Treating missing data as a match
If one reference is incomplete, the correct result is unconfirmed, not exact.
Ignoring the manufacturer
A code alone may be ambiguous or may have been copied from the wrong component.
Correcting the code by assumption
Do not silently change punctuation or characters because another format appears more common.
Confusing matching with compatibility
Technical similarity cannot turn two different complete model codes into an exact model match.
Using a board number
A T-CON, driver board, inverter, or cable code does not identify the complete LCD panel.
Frequently Asked Questions
What counts as an exact LCD panel model match?
An exact match has the same panel manufacturer and the same complete model number, including every prefix, suffix, version, and revision shown on the label. A shared base model alone is not enough to confirm an exact match.
Do spaces, hyphens, and parentheses matter?
Yes. Preserve the manufacturer's original formatting while checking the model. Sellers and databases may display punctuation differently, but you should not remove or change it unless the manufacturer documentation confirms that both formats identify the same model.
Is a matching base model with a different revision an exact match?
No. It is a related model or revision, not an exact model match. Different revisions may or may not be interchangeable, so they require a separate technical compatibility check.
Can a customer part number confirm the panel model?
Sometimes, if an authoritative parts list or manufacturer cross-reference maps that number to one complete panel model. Without that evidence, use the original panel manufacturer label as the primary reference.
What should I send if part of the model label is unreadable?
Send an uncropped photo of the complete label, close-ups from more than one angle, the full rear side of the panel, and any equipment or purchasing records. The result should remain unconfirmed if the missing characters cannot be verified.
