Time-Division Multiplexed Heating Circuit for Large LCD Panels

The patent applies periodic action by using time-division multiplexing to sequentially activate different heating lines. The control circuit controls the switching of heating lines in different time periods, allowing a single heating circuit to serve multiple heating lines through periodic activation. This resolves the contradiction by enabling larger display panels to be heated without proportionally increasing the number of heating circuits, as the same circuit resources are reused across different time intervals.

The heating circuit is designed with multi-functionality to serve multiple heating lines. Instead of dedicating one heating circuit per heating line, the heating circuit can be dynamically allocated to different heating lines based on temporal requirements. This universal approach allows the heating system to scale to larger display panels while maintaining a limited number of heating circuits, as each circuit can perform multiple heating tasks at different times.

The control circuit implements periodic control by switching between different heating lines in predetermined time intervals. This periodic action simplifies the design process because the same control logic and circuit architecture can be reused across different heating lines, rather than requiring unique control designs for each line. The time-division multiplexing approach provides a systematic framework that reduces design complexity while accommodating larger display panels.

The patent utilizes parameter changes by dynamically adjusting the activation timing and duration of different heating lines. Instead of maintaining static connections between heating circuits and heating lines, the system varies the temporal parameters of circuit activation. This parameter-based control approach simplifies design by providing a flexible, programmable method to manage multiple heating lines without requiring complex hardwired control logic for each line.

The time-division multiplexing approach allows a single heating circuit to provide effective heating to multiple heating lines by sequentially activating them. This periodic activation ensures that each heating line receives adequate power when needed, maintaining heating effectiveness without requiring multiple simultaneous heating circuits. The result is a cost reduction because fewer heating circuit components are needed while still achieving the required heating performance across the entire display panel.

The patent merges the function of multiple heating circuits into a single heating circuit through time-division multiplexing. Instead of having separate heating circuits operating in parallel, the system combines their functions by allowing one circuit to serve multiple heating lines at different times. This merging approach reduces the total number of heating circuit components required, thereby lowering the cost of the display module while maintaining the necessary heating capability.
