To communicate custom LCD specs to factories error-free: Define core specs in a standardized sheet (dimensions, resolution, interfaces, operating temperature, backlight type). Provide CAD files with precise TFT LCD outlines, cutouts, and touch panel boundaries in DXF/STEP formats. Use an RFQ checklist covering brightness, touch technology, custom sizes, and compliance. CDTech’s patented 2nd Cutting saves up to 80% on NRE for 391+ custom SKUs.

What Information Must You Include in Your LCD Specs Sheet?

Include active display area in mm, resolution in pixels, color depth, viewing angles, and pixel pitch. Add environmental specs like operating temperature from -30°C to +85°C, humidity, and shock tolerance. Specify interfaces such as RGB 24-bit, LVDS, MIPI, or SPI, plus signal timing. CDTech ensures traceability via ERP for ISO9001 and ISO14001 compliance in automotive and medical sectors.

Parameter	Standard Range	Your Custom Value
Active Area (mm)	30-250	e.g., 108.0 x 71.4
Resolution	240×240 to 1920×720	e.g., 800×480
Interface	RGB/LVDS/MIPI/SPI	e.g., RGB 24-bit
Operating Temp	-20°C~+70°C	e.g., -30°C~+85°C
Brightness	250-2300 nits	e.g., 1000 nits

Why Are CAD Files Critical for Accurate Factory Quotes?

CAD files prevent dimensional mismatches, tooling errors, and delays by defining exact outlines, cutouts, and touch boundaries. Use DXF for 2D or STEP for 3D with tolerances like ±0.5mm for frames and ±0.2mm for touch registration. CDTech’s patented 2nd Cutting technology from 2017 enables quotes from CAD without high NRE costs.

How Do You Specify Custom LCD Dimensions Without High NRE Costs?

Avoid traditional tooling with 5-15k USD NRE and months of delay by using patented 2nd Cutting for post-manufacturing precision cuts. Specify dimensions like 7.0″ x 4.8″ in RFQ with volume and timeline. CDTech’s method cuts NRE by 80% and lead time by weeks in 3,500㎡ Class 1000 clean rooms for 391+ SKUs.

CDTech Expert Views: “Our patented 2nd Cutting approach, combined with full vertical integration from LCD cutting to OCA bonding, means your CAD-specified custom size moves from quote to prototype in weeks, not months—critical for automotive and medical OEMs under IATF16949/ISO13485 timelines.”

Which Touch Panel Technologies and Interfaces Should You Specify?

Specify capacitive (CTP/PCAP) for multi-touch with I2C or resistive (RTP) for stylus/glove use. Detail finger/stylus compatibility, bezel width, haze, anti-glare, and bonding (OCA or air). Interfaces include I2C, SPI, UART. CDTech integrates CTP across 1,000+ customers with IATF16949 certification.

Feature	Capacitive (CTP)	Resistive (RTP)
Touch Points	Multi-touch	Single-touch
Durability	High (finger)	High (stylus/glove)
Cost	Higher	Lower
Environment	Indoor/outdoor	Harsh conditions

What Does an Effective RFQ Checklist Look Like?

Finalize specs sheet, attach CAD (2D/3D), select touch/backlight, confirm volume/timeline. List compliance like ISO9001, ISO13485, IATF16949, RoHS. Include traceability needs. CDTech’s ERP portal verifies specs for instant quotes to global customers.

How Do You Avoid Common CAD and Specification Errors?

Align touch overlays with references to prevent dead zones. Specify backlight cavity ±0.3mm to avoid leakage. Provide pin diagrams with voltages/timing. State temperature range like -30°C~+85°C upfront. CDTech’s 10,000㎡ facility supports design reviews to catch errors early.

FAQs

What file format should I use for CAD files when submitting an LCD RFQ?

Use DXF for 2D or STEP for 3D assembly, plus PDF with dimensions and tolerances. CDTech accepts all formats; native files ensure compatibility for precise quotes.

How much should I specify about backlight brightness and color gamut?

Specify brightness in nits (250-2300), CCT in Kelvin, NTSC gamut, and standards like ISO13485. CDTech’s clean rooms tune brightness consistently across batches.

Can I change my custom LCD specs after the RFQ quote?

Minor tweaks like ±10% brightness work; major changes re-quote. CDTech’s 2nd Cutting allows late customizations without full re-tooling—discuss early.
