Touch Display Timing Synchronization via Independent Controllers

The patent segments the timing control into separate modules: a display controller for image display timing and a touch controller for touch sensing timing. Each controller operates independently with its own timing mechanism, allowing different timing rates without requiring synchronization between them. This segmentation resolves the contradiction by maintaining operational independence (reducing complexity) while ensuring each function performs reliably at its own optimized timing rate.

The patent introduces a timing controller as an intermediary component that mediates between the display controller and touch controller. This timing controller generates appropriate timing signals for both display processing and touch sensing operations, enabling synchronized operation without requiring direct complex synchronization between the two main controllers. The intermediary simplifies the overall timing management while maintaining touch sensing accuracy.

The patent implements dynamic timing control where the display controller and touch controller can operate at different timing rates independently. The display controller manages image display timing optimized for visual output, while the touch controller manages touch sensing timing optimized for detecting various input devices (fingers, stylus, etc.). This dynamic independence allows the system to adapt to different input sources without compromising image quality, as each controller optimizes its timing for its specific function.
