Engineer-Centric Value Proposition

A 1.09" circular TFT LCD module engineered for industrial automation, medical devices, and premium IoT systems. Resolves critical design challenges with:

• Pixel-Perfect Circular UI: 240×240 RGB resolution (0.1158mm pitch) eliminates jagged edges.
• Extended Temp Range: -20°C to +70°C operation (IEC 60068-2-1/2 certified).
• GC9A01 Controller: Integrated driver reduces MCU load via SPI 4-wire protocol (ARM/RISC-V compatible).

Ideal for replacing OLEDs in space-constrained, high-reliability HMI applications.

Critical Technical Specifications

Competitive Advantages

① Plug-and-Play SPI Integration

• Zero-Code Drivers: Arduino/STM32 HAL libraries reduce development time by 2 weeks.

• Dynamic Power Control: PWM dimming (100Hz–1KHz) cuts standby power 37% vs. competitors.

② Medical/Industrial Durability

• Chemical-Resistant Surface: Withstands disinfectants (EN 60601-1 compliant).

• Anti-Shock Design: 30.59×32.98mm housing with mounting holes.

③ Optical Excellence

• Circular Pixel Optimization: Dedicated γ-correction (ΔE<2.5 at edges).

• 85° Omni-Directional Viewing: CR>10 at 12/3/6/9 o’clock positions.
