The driver IC of Hawkeye 350 aims at micro-LED display applications. Hawkeye 350 is scan-sharing architecture and can support a maximum of 64 scans. To meet high pixel density demand, Hawkeye 350 is also a 48-channel highly integrated solution. This feature can simplify the PCB layout and make modular design possible.
In the past, it is hard for LED displays to use high-scan design and keep great visual performance. However, Hawkeye 350 has the PWM enhancement function that helps reduce EMI problems and achieve HDR-Optimized*.
* 16-bit grayscale at 4KHz refresh rate at 32-scan design or above.
For smaller pixel pitch displays, the minimum current of driver IC should be lower. The minimum current of Hawkeye 300 is 500uA, and the minimum current of Hawkeye 350 is low to 100uA that is the lowest output current on the market. It means that Hawkeye 350 sets a new milestone for the whole industry.
According to the experimental data, the ratio of driver IC power consumption to total power consumption increases as pixel pitch decreases. The total driver power consumption equals to IDD times the number of driver ICs. The most straightforward method to lower total LED display power consumption is to cut total driver IC power consumption, which the industry is working on. Hawkeye 350 represents a highly integrated driver IC that supports 64 scans with reduced IDD. Also, the supply voltage of Hawkeye 350 is low to 3.3V. Plus Dynamic+ power-saving function, all of these elements make Hawkeye 350 a perfect power-saving solution to mini-/micro-LED displays.
The recommended pixel pitch of Hawkeye 350 is from 0.4mm to 1mm.
