Chengdu Jiehua Technology Co., Ltd. is located in Area A of Chengdu Tianfu Software Park. The company focuses on technological innovation and software research and development. The company's senior managers have rich management and technical experience in well-known Internet companies.

Based on years of research and development on screen projection and device control, we have achieved screen mirroring of up to 60 FPS (frames per second) with screen resolution of 1080P. Our patent pending SFC technology solved the compatibility issues for Android phones, compatible with more than 6000 different Android devices. Today, Sigma has been the expert in screen projection and device control for mobile devices, PC, TV and projectors.

We have a rich portfolio of products based on our core competencies. Our flagship product Total Control is widely used by consumers. Total Control supports screen mirroring and device control of multiple Android devices simultaneously. It also offers scripting capabilities and a rich set of APIs to automate complicated or repeated tasks with ease.

TC Games was created by utilizing Sigma's fast screen mirroring and speedy device control to allow users to enjoy mobile games on PC's big screen, keyboard and mouse. TC Games also provides live broadcast capability.

As the customer demand for screen mirroring grows, we have also launched an easy-to-use live screen casting tool: TC Display.
