The Avatr 07 is equipped with the “Interactive Outdoor Quarter Moon HALO Interactive Screen”, in the middle of the front hood and windshield of the vehicle, which is an innovative application of miniLED technology in the on-board display. Set maker is Anrui Wipac; for the Avatr 11 & 12 the set maker was Liaowang.
Behind such a smart interactive screen, the miniLED display driver comes from Chipone (ICND7001 and ICND7201). These are the first set of mass-produced automotive chips of Chipone’s automotive business unit.The two chips are independently designed by Chipone and packaged and mass-produced by the domestic supply chain to produce domestically produced automotive mini LED display driver chips.
The two chips have undergone nearly 30 rigorous tests and verifications, such as high-acceleration stress tests and wide temperature range operations and have officially passed the AEC-Q100 authoritative certification in the field of automotive electronics in 2023, perfectly adapting to the high-performance requirements of existing automotive application components such as intelligent cockpits and intelligent interactions.
Among them, ICND7001 adopts QFN56 package, supports 48-channel output, 16-bit dimming, 7680hz high refresh, and built-in GCLK to effectively reduce electromagnetic interference. The ICND7201 is available in a QFN16 package, integrating 8 power PMOS outputs, with a maximum continuous current of 2.5A and 8 levels of anti-contrast potential, which can effectively remove ghosting on LEDs.
