Touch Panel System Using Stylus Pen Drive Lines for Signal Transmission

The patent segments the quantitative characteristic value into multiple individual information items, where each item can be independently encoded and transmitted. Instead of transmitting the entire value as a single complex code, the system divides it into separate components that can be sent sequentially or in parallel, reducing the complexity of each individual signal while maintaining complete information transmission capability.

The patent employs periodic transmission of information bits, where each bit of the quantitative characteristic value is transmitted in separate time slots or cycles. This periodic approach allows the receiver to reconstruct the complete value over time without requiring complex simultaneous signal processing, thereby reducing signal complexity while preserving full information content.

The patent segments the multi-bit quantitative characteristic value into multiple single-bit or low-bit information items. Each segment is independently encoded using simple code patterns, making signal identification straightforward. The receiver reconstructs the complete high-precision value by combining these simple segments, thereby maintaining measurement precision while dramatically reducing signal identification complexity.

The patent changes the parameter representation from a single high-bit code to multiple low-bit codes. By transforming the information structure from one complex parameter to several simple parameters, the system achieves the same precision level with much simpler signal identification logic and reduced computational burden.

The patent segments the information transmission into multiple simple sequential steps, where each step transmits one bit or a small portion of the quantitative characteristic value. This segmentation allows the use of simple sequential driving logic while minimizing transmission time through efficient bit-by-bit transmission optimized for the touch panel's scanning rate.

The patent ensures continuous transmission of information bits during the touch panel's driving cycle, utilizing every available time slot efficiently. By maintaining continuous useful action throughout the scanning period, the system minimizes idle time and achieves fast transmission despite using simple sequential driving methodology.

The patent segments both the spatial dimension (multiple pens) and the data dimension (multiple bits per pen). Each electronic pen transmits its information bits sequentially through simple drive patterns, allowing the receiver to decode each pen's data independently before combining results. This segmentation approach enables parallel processing of multiple pens without creating complex overlapping decoding scenarios.

The patent uses periodic transmission cycles where each electronic pen completes its full information transmission within a defined period. This periodic structure allows the receiver to synchronize and decode multiple pens systematically, processing one complete set of information per cycle while maintaining high transmission speed through efficient use of parallel channels.
