快速回答： Buyers comparing 光引发剂 1206, 光引发剂 OXE-01, and 光引发剂 OXE-02 for display photoresist work should usually sort the shortlist by exposure route, pigment burden, and film build before debating names. 1206 is the sharper first screen when the project is close to 365 nm exposure, ultra-thin films, and black-pigment or colored systems. OXE-01 deserves earlier attention when the program is centered on low-yellowing precision patterning and broader continuity across display layers such as color filters, black matrix, spacer materials, microlens materials, overcoat layers, and dielectric or insulating layers. OXE-02 moves up when the line wants a 375 nm LED route, a broader documented absorption window, or stronger documented coverage across colorless and colored systems.
That is the commercially useful split. These three products overlap in display-material discussions, but they should not be treated as interchangeable.
Why this comparison page is worth publishing
Longchang already has application pages for color filters, black matrix, spacer materials, overcoat layers, and dielectric layers. But many buyers do not start with one layer name. They start with a product-comparison question: which photoinitiator should we sample first for display photoresist work across the program?
That intent is distinct from an application page. It is a product-comparison page that helps a buyer narrow the first sample plan before diving into a single-layer article.
Quick comparison table: 1206 vs OXE-01 vs OXE-02
| Buying factor | 1206 | OXE-01 | OXE-02 |
|---|---|---|---|
| Named LED or wavelength position on company page | High sensitivity to 365 nm | LED365nm | LED375nm |
| Absorption detail shown on company page | Not listed in the same format, but positioned for 365 nm sensitivity | 252 / 328 | 295 / 368 / 380 / 400 |
| Colored or black-pigment handling | Suitable for colored systems including black pigment; can withstand up to 35 wt% carbon black | Useful in color-filter resists and black-matrix manufacturing | Directly positioned for color photoresists, black matrices, and both colorless and colored systems |
| Thin-film screening logic | Strongest direct support for ultra-thin 1 to 30 μm films | More general display-patterning and low-yellowing route | More general colored-system and broader-spectrum route |
| Low-yellowing positioning | Not the main headline on the page | Yes | Yes |
| Broader display-material crossover | Color filters, photosensitive inks, electronic material inks | Color filters, black matrix, spacer, microlens, overcoat, dielectric or insulating layers | Color photoresists, black matrix, spacer, microlens, covering, dielectric or insulating layers |
| Best first-screen signal | 365 nm thin-film and black-pigment route | Low-yellowing display-patterning route | 375 nm and broader colored-system route |
This table does not replace formulation work, but it usually removes the weakest starting assumption.
When 1206 is the better first fit
Longchang’s 1206 page gives the clearest direct support for buyers working on colored display systems with thin films and black-pigment pressure. The page positions 1206 as highly sensitive to 365 nm, suitable for TFT-LCD flat-panel display color filters, photosensitive inks, and electronic material inks. It also states that 1206 is suitable for colored systems, including black pigment systems, can withstand up to 35 wt% carbon black pigment, and is especially relevant to ultra-thin 1 to 30 μm curing systems.
That makes 1206 the strongest first screen when:
- the display photoresist project stays close to a 365 nm exposure route
- the formulation is heavily pigment-loaded or black-pigment-sensitive
- the film is very thin and the team wants a product page with direct ultra-thin-film language
- the line is closer to color-filter or photosensitive-ink style behavior than to a broader low-yellowing display-platform screen
1206 should not automatically lead every comparison, but it becomes very hard to ignore when black-pigment burden and ultra-thin film build are the real bottlenecks.
When OXE-01 is the better first fit
OXE-01 is a cleaner first screen when the buyer wants a low-yellowing display-photoresist route with broad display-layer continuity. Longchang positions OXE-01 as an oxime ester photoinitiator with high photosensitivity 和 low yellowing, suitable for UV-curable photoresist formulations either alone or with other photoinitiators or sensitizers. The page directly mentions color-filter resists, black-matrix manufacturing, spacer materials for LCD, microlens materials, overcoat layers, and dielectric or insulating layers, and names LED365nm with absorption peaks at 252 and 328.
OXE-01 usually deserves the first slot when:
- low yellowing is a hard requirement rather than a nice-to-have
- the process sits near 365 nm style exposure but the buyer wants broader display-layer crossover than a narrow 1206 screen
- the team wants one product discussion that can stretch across color filters, black matrix, spacer, microlens, overcoat, and dielectric work
- the line is solving a general display photoresist qualification problem, not only an ultra-thin black-pigment one
If the buyer wants a safer platform candidate across several related display layers, OXE-01 is often the cleaner first review point.
When OXE-02 should move ahead in the shortlist
OXE-02 becomes the stronger first screen when the project needs a broader wavelength conversation and stronger direct coverage of colored-system display photoresists. Longchang’s OXE-02 page names LED375nm, lists absorption peaks at 295, 368, 380, and 400, and states that OXE-02 can be used in both colorless and colored systems. The same page directly positions it for color photoresists and black matrices in LCDs, along with spacer materials, microlens materials, covering layers, and dielectric or insulating layers.
OXE-02 usually deserves the earlier slot when:
- the line is built around 375 nm LED exposure
- the buyer wants a broader documented absorption window before sampling
- the display photoresist work is tightly tied to colored systems or black-matrix-style curing difficulty
- the team wants one candidate that is already described by Longchang for both colorless and colored use
That makes OXE-02 a strong product-comparison answer when OXE-01 feels too narrow on wavelength and 1206 feels too specialized around 365 nm thin-film black-pigment screening.
How buyers should choose before sampling
1. Start with the lamp, not the product name
If the actual route is close to 365 nm and the problem is very thin or pigment-heavy, 1206 often deserves the earliest look. If the route is 365 nm but the buyer wants a broader low-yellowing display platform, OXE-01 often fits better. If the route is 375 nm LED or needs broader spectral coverage, OXE-02 usually moves ahead.
2. Decide whether pigment burden is the real commercial risk
Some projects mainly need low-yellowing display cleanliness. Others mainly need a photoinitiator that survives black-pigment blocking or colored-system cure difficulty. Those are different selection problems, and they do not rank 1206, OXE-01, and OXE-02 the same way.
3. Keep film build visible early
The strongest direct thin-film support in this trio sits with 1206. That matters when the qualification problem is not broad display compatibility, but a very thin and technically unforgiving imaging layer.
4. Use neighboring display layers as a tiebreaker
If the same development program also touches spacer materials, microlens materials, overcoat layers, dielectric layers, or black matrix manufacturing, OXE-01 or OXE-02 can become more attractive because the company pages already position them across that wider display-material branch.
5. Keep the first sample round disciplined
Many buyers do not need a large sample list. A practical first screen is often one thin-film black-pigment benchmark, one low-yellowing display-platform benchmark, and one broader 375 nm colored-system benchmark. That is exactly where 1206, OXE-01, and OXE-02 each earn a distinct place.

常见问题
Which is better for display photoresists, 1206, OXE-01, or OXE-02?
There is no universal winner. 1206 usually moves ahead when 365 nm thin-film and black-pigment behavior is the real issue. OXE-01 usually moves ahead when low yellowing and broader display-layer continuity matter more. OXE-02 usually moves ahead when the project needs 375 nm LED fit, broader absorption coverage, or stronger direct colored-system positioning.
Why is 1206 not just a backup to OXE-01 and OXE-02?
Because Longchang’s 1206 page has the clearest direct language around 365 nm sensitivity, ultra-thin 1 to 30 μm films, and heavy carbon-black tolerance. In the right display photoresist project, that is not a secondary detail. It is the main selection driver.
When should I choose OXE-02 before OXE-01?
Choose OXE-02 earlier when the process is built around 375 nm LED exposure, when the buyer wants broader absorption coverage, or when the same qualification path must stay comfortable across both colorless and colored display systems.
Can one product support several display-material applications?
Sometimes yes, and that is part of the commercial value here. Longchang already positions OXE-01 and OXE-02 across several related display-material applications, which can simplify supplier qualification for connected layers.
Need a tighter display-photoresist shortlist?
If your team is comparing 1206, OXE-01, and OXE-02 for display photoresists, start with the real exposure route, the pigment burden, and the film build before widening the sample set. That usually leads to a cleaner first qualification round than treating all three products as generic display photoinitiators.
