Display interface methods and systems

摘要

Methods and systems for implementing video driving circuitry are disclosed. For example, in an embodiment, a system for driving a plurality of different types of video devices is disclosed. The system includes, for example, a System on a Chip (SoC) that itself includes a Liquid Crystal Display (LCD) controller circuit configured to generate digital video data, a first synchronization signal for controlling a first characteristic of the digital video data, and a second synchronization signal for controlling a second characteristic of the digital video data. The SoC further includes a delay circuit configured to variably delay the first synchronization signal and the second synchronization signal relative to the digital video data to generate a delayed first synchronization signal and a delayed second synchronization signal.

1. A device for driving a plurality of video devices, the device comprising:
a controller circuit configured to drive the video devices including at least a digital interface and an analog interface and to generate digital data and synchronization signals for controlling characteristics of the digital data; and a delay circuit configured to variably delay the synchronization signals relative to the digital data to generate a delayed first synchronization signal and a delayed second synchronization signal, the delayed first synchronization signal and the delayed second synchronization signal compensating a delay caused by a digital-to-analog converter (DAC) converting the digital data to an analog signal.
