3D 主动式快门眼镜 | 赛普拉斯半导体
3D active shutter glasses are used to view 3D images on TVs, displays, and projectors. 3D glasses require a precision analog front end (AFE) for signal gain, noise filtering, and automatic gain control. They use liquid crystal shutters requiring voltages from 10V-20V source depending on manufacturer. The glasses will be run with either a coin cell or rechargeable batteries. USB interface to the glasses can be used for recharging and as a communication interface. Mechanical or CapSense switches can be implemented as the user interface.
PSoC® 1 and PSoC 3 enable a scalable solution that integrates the precision analog front end (AFE), shutter drive, battery charging and monitoring, and user interface into a single chip. The flexible analog architecture also allows designers to create a programmable solution for universal glasses. PSoC also enables feature innovation with CapSense buttons and proximity sensing, as well as USB connectivity.
This application note describes several techniques for implementing a peak detector in PSoC 3 and PSoC 5LP.
This application note explains implementation of state machines using the PSoC® 3/PSoC 4/PSoC 5LP family of devices. Mealy and Moore state machine implementations are shown with associated projects.
The CY8CKIT-001 PSoC® Development Kit (DVK) provides a common development platform where you can prototype and evaluate different solutions using any one of the PSoC 1, PSoC 3, PSoC 4, or PSoC 5 architectures.
