Performance & Architecture Advantages
True 4-Color Display
High-contrast, highly reflective black/white/red/yellow — ideal for retail ESL tags requiring clear price and promotion visibility.
Ultra-Low Power
15mW typical operation, 0.0012mW deep sleep, and 0.41µA sleep current — years of battery life for wireless ESL deployments.
All-in-One Driver IC
JD79663CA integrates gate driver, source driver, MCU interface, timing controller, oscillator, DC-DC, SRAM, LUT, and VCOM — fewer external components.
On-Chip OTP & Temp Sensor
Waveform stored in on-chip OTP for guaranteed stability. Built-in temperature sensor with external LM75 support ensures optimal image quality across environments.
