3.5 Inch 320x240 TFT LCD Module 24-Bit RGB + SPI High Brightness 85C - VXT350CQH-45-W

Victronix 3.5 inch 320x240 Sunlight Readable TFT Module different from other manufacturers? At first, its 1000 cd/m² brightness, 300:1 contrast ratio, and viewing angles of Horizontal: ±60°, Vertical: +50°/-60° ensure vivid imagery. Secondly, the device supports a 24-bit parallel RGB interface + SPI control (HX8238D driver IC). Additionally, it features a 6-die white LED backlight with a lifespan of 30,000 to 50,000 hours, ensuring reliable performance in various industrial applications. Besides, it meets RoHS standards and passes rigorous reliability tests (thermal shock, humidity, storage) to operate flawlessly in extreme temperatures (-20°C to +85°C) and withstand harsh storage conditions (-30°C to +85°C). This Victronix 3.5 inch TFT Module is suitable for Industrial HMIs, medical devices, test and measurement equipment, portable instruments, and other embedded systems requiring a bright, reliable, and compact color display solution.

Where It Gets Used

EV charging piles and charging stations — 1000 cd/m² for daylight, +85 °C for a sealed enclosure in summer.
Outdoor and semi-outdoor industrial control cabinets — anti-glare polarizer and a fifteen-degree temperature margin over the usual range.
Construction and agricultural machinery panels — heat, vibration and direct sun.
Elevator and lift display boards — floor number, direction arrows and status text, at 115.98 PPI and 150 KB.
Outdoor vending, ticketing and self-service terminals.
Industrial HMI and machine sub-panels near heat sources — ovens, drives, compressors, hydraulic units.
Handheld and portable field instruments — 150 KB frame buffer, SPI setup, 0.576 W backlight.
Test and measurement equipment — square pixels keep scales, traces and labels true.
Kiosk and access control sub-displays sited in direct or reflected light.
Retrofits of existing 3.5-inch 320 × 240 equipment — one of the most widely deployed small-panel formats still in service.
