Additional Information

Interface & Control: 2-lane MIPI DSI interface for high-speed display data; supports TE (Tearing Effect) output and PWM backlight control.
Power Sequencing: Strict power-on/off timing required (VCI → IOVCC → RESET → MIPI signals) to ensure stable initialization.
Touch Integration: Capacitive touch panel driven via I2C; includes interrupt (INT) and reset (RESET) pins for host control.
Mounting: Compact square design with through-hole or surface-mount compatibility; refer to mechanical drawings for precise placement.
Cleaning: Use only isopropyl alcohol or ethyl alcohol with a soft cloth. Avoid water, ketones, and aromatic solvents.
ESD & Handling: Operate in grounded, static-safe environments (30–60% RH recommended). Use anti-static packaging during storage and transit.
Storage: Store in sealed anti-static bags at 0–40°C, ≤80% RH, away from direct light, acids, alkalis, or corrosive gases.
Compliance: Designed to meet industrial reliability standards; RoHS compliant.

This TFT-LCD-Modul from JicTech combines a high-resolution square display with responsive capacitive touch in an ultra-compact form factor, making it an ideal choice for space-constrained applications that demand clarity, interactivity, and durability.
