FAQ TFT LCD — tailles, luminosité, température, tactile, MOQ et délais | DISEA
Réponses aux questions que se posent le plus souvent les ingénieurs achats avant de qualifier un fournisseur de TFT LCD : couverture des tailles, lisibilité en plein soleil, plage de température, performance tactile, capacité, certifications, qualité, délais, MOQ, prix, remplacements directs, personnalisation, garantie et export.
Do you reliably cover the full small-to-large TFT size range?
Yes. DISEA's standard catalog lists 169 TFT LCD models from 0.96 to 21.5 inch, spanning IPS, TN, round, bar and square form factors. The range is produced continuously rather than project-by-project, so steady supply is the default, not the exception.
Total capacity: 240,000,000 pcs/year (peaking at 2,000,000 pcs/month) from our own line — enough headroom to hold both volume and lead-time commitments across the full size range.

Are the modules sunlight readable?
Yes. DISEA offers a high-brightness line up to 1500 nits (20 standard models ≥1000 cd/m²) with optional optical bonding and transflective solutions that keep the image legible under direct sunlight. For outdoor HMI, pair high brightness with a bonded cover lens and anti-glare treatment.
Browse sunlight-readable displays or tell us your ambient-lux target on the contact page.
Do wide-temperature modules really operate -30°C to +85°C?
Yes. 27 standard models are rated for -30°C operation (storage down to -40°C, with the extended range qualified to +85°C / -40~+90°C on request). Each lot ships with temperature-cycle verification, and a third-party high-low temperature cycling report (≥500 cycles, -40~+90°C) is available on request.
See the wide-temperature display line.
Are they durable and high quality?
Cover-glass options reach 7H on the Mohs scale (≈9H by pencil-hardness test), and modules are built for industrial duty: 1.5 m drop test / IK08 impact rating on the covered versions. Every unit passes incoming and outgoing inspection against the spec sheet.
Is the touch responsive?
Our PCAP line (31 standard models) supports 10-point multi-touch, glove and wet-hand operation, with ≥100 Hz sampling rate. Controllers are selected for industrial EMI environments and can be tuned for the thickness / cover-lens stack-up.
How large is your production capacity?
DISEA runs its own factory in Zhaoqing (Guangdong) with 23,700 m² floor area and an annual capacity of 2,400 ten-thousand pieces/year (24,000,000 pcs); single-month peak delivery can reach 200 ten-thousand pieces. This owned capacity is what lets us hold both volume and lead-time commitments.
Are you certified and compliant?
Yes — DISEA is certified to ISO 9001 (No. CN-QMS-2023-0812, valid to 2028-05-16) and ISO 14001 (No. CN-EMS-2023-0765, valid to 2028-04-22). Products carry RoHS, REACH and CE as standard. An automotive-grade (IATF 16949) flow is available for qualifying programs.
Is quality stable?
Outgoing defect rate is controlled to ≤80 PPM, with a 12-month average yield of 98.2%. We run SPC on key processes and feed yield back into incoming-quality and process controls.
How fast can you deliver?
Typical prototype / sampling cycle is 5–7 working days and mass-production lead time is 18–25 working days, with an on-time delivery (OTD) rate of 96.5%. Expedited sampling is available for NPI programs.
Is the MOQ low?
Standard MOQ is 500 pcs. We accept small batches (<500 pcs) for prototypes and bridge builds, with a unit premium of about +15%. Tell us your volume and we'll quote.
Are prices competitive?
As a direct manufacturer we quote ex-works. Example: a 7" 800×480 TFT (TN/IPS, LVDS) at FOB Shenzhen:
| Volume | Unit price (FOB Shenzhen) |
|---|---|
| ≥5,000 pcs | USD 7.80 |
| 1,000–4,999 pcs | USD 8.30 |
| 10,000+ pcs | request a quote |
Share your BOM and target volume for a firm quote; an annual-volume rebate applies on multi-year framework agreements.
Can you replace brand-name panels?
Yes. DISEA provides pin-to-pin compatible drop-in replacements for selected legacy Mitsubishi / Innolux panels. Electrical deviation is held within: supply voltage ±5%, brightness ±10%, contrast ±15%, signal timing ±3%. This is handled under our custom / ODM flow.
Can you customize and develop?
Yes. Our 72-engineer R&D team takes requirements from concept to EVT; for shaped / odd-form displays the concept-to-EVT cycle is 6–8 weeks with NRE from USD 4,800–7,500 depending on structural complexity. FPC, backlight, cover-lens, bonding and interface are all customizable.
What about warranty and after-sales?
Standard warranty is 12 months. Annual RMA return rate is kept ≤0.75%, and a failure-analysis (FA) report is delivered within 5–7 working days of receipt. We support your field returns with root-cause analysis, not just replacements.
Are you easy to work with on export and logistics?
DISEA exports 62% of output, holds RoHS / REACH / CE, and ships to major markets (North America, Europe, Asia-Pacific) under common Incoterms — FOB Shenzhen, CIF and DAP. Documentation, label and packing lists follow your template.
