Product Description

Company Introduction

DWIN is one of the few companies in the industry that can independently develop and design dedicated chips for human-computer interaction based on market experience. DWIN’s ASIC design removes the redundant functions of common general-purpose chips, strengthens the related performance of human-computer interaction (such as built-in high-speed video memory, etc.), helps users reduce the overall hardware cost, and also reduces the development difficulty of the interactive part, so that customers can focus more on their core technologies, so as to promote the development and update iterations of products and technologies.
