LTDCM-4035 Dual-Optical Path Display Color Analyzer for Next-Generation Fordable Display Inspection

$16,500.00 USD

Two measurements. One device. Zero compromises.

The LTDCM-4035 is the first color analyzer that can test two screen areas simultaneously. Built specifically for modern displays - from foldable phones to under-display cameras.
Why it matters: Instead of testing one spot at a time, you get dual measurements instantly. That means faster quality control, better accuracy, and less time spent moving equipment around.
Perfect for: Smartphone testing, foldable displays, automotive screens, and any next-gen display technology that demands precision.

Features

Dual optical path design Two independent optical systems in one instrument, enabling simultaneous measurement of different screen areas - dramatically improving testing speed while maintaining precision.
Expanded accuracy-guaranteed range of luminance: Wider range of measurement accuracy and repeatability. Luminance: 0.0001-6,000cd/m² – Chromaticity: 0.001-6,000cd/m². It enables precise measurement and calibration of chromaticity and gamma characteristics for OLED and HDR displays that require ultra-low luminance measurement capabilities.
High reliability with ultra-fast measurement speed, Delivering consistent results with ultra-low luminance detection (1 sec at 0,0001 cd/m²) and high-resolution performance.
Comprehensive parameter analysis covering luminance, chromaticity, gamma, and flicker, meeting the precise measurement and calibration requirements for OLED and HDR displays requiring ultra-low luminance testing
Specialized under-display camera (UDC) measurement capability, Optimized for displays with under-panel camera integration.
Streamlined workflow integration, Supporting both screen module calibration and final product display QA processes.
Full software support: PC software in addition to Software Development Kit (SDK)

Applications

Case 1: Foldable Phone Simultaneous Data Collection

"Real-time dual measurement for foldable displays"

The LTDCM-4035 enables simultaneous measurement of both folded screen sections, capturing color and brightness data from multiple areas at once. This eliminates the need for sequential testing, dramatically reducing inspection time for complex foldable device geometries.

Key Benefits:

Instant dual-zone data capture
Synchronized measurement for folded configurations
Reduced testing complexity for multi-panel displays

Case 2: Compact Design for High-Volume Online Inspection

"Automated production line integration for mass manufacturing"

The system's compact footprint allows seamless integration into automated production lines. With mobile controller connectivity via USB or RS-232C, it enables continuous quality inspection of display modules as they move through the manufacturing process.
