빠른 답변: For LCD negative photoresist, the first useful screen is usually wavelength fit plus pigment burden, not a broad generic UV-curing claim. CHLUMINIT® OXE-06 deserves first attention when the process is centered on LED395 nm and the buyer needs a product that Longchang directly positions for negative photoresist of LCD with stated tolerance for 35% by weight of carbon black pigment. 광개시제 1206 becomes a strong 365 nm option when the job behaves like a colored-system or ultra-thin-film display route, because Longchang positions it for TFT-LCD color filters, photosensitive inks, electronic material inks, and black-pigment systems. 광개시제 OXE-02 구매자가 원할 때 가격이 올라갑니다. 375 nm high-sensitivity route ~을 위한 color photoresists and black matrices in LCDs, especially in colored systems where deep and rapid curing matters.
That is the useful commercial split. LCD negative photoresist buyers usually get a better shortlist when they separate 395 nm negative-photoresist fit, 365 nm colored thin-film behavior, 그리고 375 nm high-sensitivity display-photoresist crossover 샘플을 요청하기 전에.
Why LCD negative photoresist needs a tighter shortlist
LCD photoresist work is less forgiving than a broad coatings or ink discussion. Buyers usually care about several process pressures at the same time:
- Exposure-window fit: a strong photoinitiator in the wrong LED window is still the wrong starting point.
- Pigment and opacity burden: black matrix, dark-color, or otherwise optically difficult systems can behave very differently from cleaner photoresist routes.
- Thin-film and precision behavior: display-related work often punishes weak cure consistency quickly.
- Yellowing and appearance sensitivity: display applications usually reward cleaner optical behavior and disciplined selection.
- Qualification efficiency: testing too many generic UV-curing candidates slows sampling instead of helping it.
That is why a short buyer-relevant comparison is more useful than a long undifferentiated list.
If you need the broader branch first, start with Photoinitiator for Display Photoresists or the more general 광개시제 선택 가이드.

| 제품 | 최적 첫 번째 적합 | 구매자들이 왜 그것을 후보에 올리는가 | 첫 번째 옵션이 아닐 때 |
|---|---|---|---|
| CHLUMINIT® OXE-06 | LCD negative photoresist routes centered on LED395 nm and high carbon-black tolerance | Longchang directly positions it for negative photoresist of LCD, states LED395 nm, and states tolerance for 35% by weight of carbon black pigment ~와 함께 zero VOC emissions | When the process is clearly centered on 365 nm or a broader color-photoresist and black-matrix route rather than a direct 395 nm negative-photoresist screen |

When OXE-06 is the better fit
OXE-06 is the clearest first-choice route when the buyer wants a product that is already positioned by Longchang for the exact LCD negative-photoresist use case.
- Direct LCD negative-photoresist positioning: the current Longchang page explicitly says it is suitable for negative photoresist of LCD.
- LED395 nm fit: the same page highlights LED395 nm, which gives buyers a much tighter first filter than a generic UV-curing description.
- 카본블랙 내성 Longchang states tolerance for 35% by weight of carbon black pigment.
- Cleaner processing story: the page also states zero VOC emissions.
If the project is specifically an LCD negative-photoresist qualification and the line logic starts at 395 nm, OXE-06 should usually be in the first sample round.
1206이 더 적합할 때
1206 deserves earlier review when the buyer’s real problem looks less like a single 395 nm screen and more like a 365 nm colored-system or ultra-thin-film display decision.
- 365 nm sensitivity is explicit: Longchang states high sensitivity to 365 nm.
- Black-pigment relevance is explicit: the page states suitability for colored systems, including black pigment systems, and tolerance up to 35 wt% 카본 블랙 안료.
- Ultra-thin-film relevance is explicit: 롱창 1206번 포지션 1~30 μm ultra-thin-film curing systems.
- Display crossover is direct: the same page places 1206 in TFT-LCD flat panel display color filters, photosensitive inks, and electronic material inks.
That makes 1206 especially useful when the LCD route includes black-pigment burden, color-filter-adjacent work, or thin imaging layers that behave more like a difficult display ink or color-resist formulation than a simple broad negative-photoresist screen.
OXE-02가 더 적합할 때
OXE-02 becomes more attractive when the buying decision is really about high-sensitivity display color-photoresist and black-matrix manufacturing rather than only a narrow negative-photoresist label.
- 375 nm route: Longchang positions OXE-02 at LED375 nm.
- Broad absorption support: the page lists absorption peaks at 295/368/380/400.
- Colored-system fit: Longchang states OXE-02 can be used in both colorless and colored systems.
- LCD display relevance: the application section directly names color photoresists and black matrices in LCDs.
- Deep curing language in colored systems: Longchang further describes high sensitivity and deep rapid curing in pigmented systems.
If the buyer’s first question is how to keep a colored LCD photoresist or black-matrix route moving at a 375 nm-centered exposure window, OXE-02 often deserves the earlier screen than a purely 365 nm or 395 nm-first option.
How buyers should choose
1. Start with the actual LED window
If the process is already fixed at 395 nm, OXE-06 deserves priority. If it is centered at 365 nm, 1206 moves up. If the route is closer to 375 nm display-photoresist qualification, OXE-02 becomes more relevant.
2. Separate black-pigment burden from cleaner systems
Do not treat a difficult black-matrix-style screen and a cleaner colorless route as the same first sample plan. OXE-06 and 1206 both carry strong carbon-black language, while OXE-02 carries stronger color-photoresist and colored-system language.
3. Keep thin-film behavior visible
If the line behaves like an ultra-thin imaging layer, 1206 deserves extra attention because Longchang directly positions it for 1 to 30 μm systems.
4. Do not over-expand the first sample round
A better commercial answer usually comes from testing two or three routes that truly match the process, not from screening a long list of generic UV-curing products.
For adjacent display-branch decisions, continue with Photoinitiator for Color Filters, Photoinitiator for Black Matrix, 또는 1206 vs OXE-01 vs OXE-02.

자주 묻는 질문
Which photoinitiator is best for LCD negative photoresist?
There is no universal best choice. In Longchang’s current product set, OXE-06 is the clearest first screen for LED395 nm LCD negative photoresist, 1206 is strong for 365 nm colored and ultra-thin display systems, and OXE-02 is a strong 375 nm option for color photoresists and black matrices in LCDs.
Why is wavelength fit more important here than in a generic UV-curing page?
Because LCD negative photoresist selection is process-sensitive. A product can look strong in broad UV-curing language and still be the wrong first sample if the real line window is 365, 375, or 395 nm.
When should 1206 move ahead of OXE-06?
1206 should move up when the project is centered on 365 nm, black-pigment systems, or ultra-thin display layers that look closer to color-filter or photosensitive-ink behavior than to a direct 395 nm LCD negative-photoresist route.
When is OXE-02 the better first sample?
OXE-02 becomes the better first sample when the route is centered on 375 nm and the buyer is qualifying colored display photoresists or black-matrix manufacturing in LCDs.
Need a tighter LCD negative-photoresist shortlist?
If your LCD line is being limited by exposure-window mismatch, carbon-black burden, or inconsistent thin-film cure, start by separating the 395 nm, 365 nm, and 375 nm routes before you request samples. That usually leads to a faster and cleaner supplier screen than treating all display photoinitiators as interchangeable.
