Product Features
Ultra-Sharp 166 PPI Clarity: With 166 pixels per inch on a 3.5" panel, text rendering and waveform details are exceptionally crisp, eliminating pixelation and reducing eye strain during extended field or clinical use.
Classic Portrait HVGA Format: 320×480 resolution in a 2:3/3:2 aspect ratio provides optimal vertical workspace, ideal for displaying multi-line diagnostic data, code lists, or tall schematics on handheld devices without scrolling.
Exact 00XA Variant Match: Genuine CPT CLAF035HA21 00XA ensures plug-and-play compatibility with your system's specific driver board and MIPI/RGB interface, preventing signal timing or backlight control issues.
Compact Professional Durability: Built to withstand continuous operation, vibration, and thermal cycling in demanding field, factory, and clinical environments while maintaining an ultra-slim, lightweight profile.
Grade A+ Quality Guaranteed: 100% tested before shipment to ensure zero dead pixels, uniform WLED backlight brightness, and flawless high-bandwidth signal transmission.

Frequently Asked Questions
Is this a complete LCD module or just an open cell glass?
This listing is for a complete TFT-LCD Module (LCM), which includes the integrated WLED backlight system and FPC connector. It is NOT an open cell (bare glass without backlight). If your equipment requires a bare cell for custom COG/COF bonding, please contact our engineering team for specialized open cell sourcing.
What does the "00XA" suffix mean in CPT CLAF035HA21?
The "00XA" suffix indicates a specific hardware revision by CPT, defining the exact interface type (MIPI DSI lanes vs RGB), backlight driver voltage, FPC pinout mapping, and optical film configuration. Substituting a panel with a different suffix will likely result in incompatible connectors, wrong voltage, or no display. Always match the exact 00XA suffix for plug-and-play installation.
Why is 166 PPI important for a 3.5-inch handheld device?
At 166 PPI, the CLAF035HA21 offers significantly sharper text rendering and smoother waveform curves compared to standard QVGA 320x240 (114 PPI) 3.5" panels. For doctors reading subtle grayscale variations in portable ultrasound, or engineers analyzing high-frequency signals on handheld oscilloscopes, this extra pixel density drastically improves diagnostic accuracy and reduces visual fatigue.
