Bidirectional Interface Circuit for Infinitely Expandable Display

The patent merges the control functions by having multiple data drivers share a single timing controller through bidirectional interface circuits. Instead of each display unit having its own control printed circuit board and ASIC, the timing controller is commonly connected to multiple data drivers, consolidating control resources and simplifying the overall connection structure while maintaining independent control capability.

The bidirectional interface circuit serves multiple functions: it transmits data signals from the timing controller to data drivers, transmits clock signals, and enables bidirectional communication. This multi-functional interface eliminates the need for separate control circuits in each display unit, reducing connection complexity while preserving control capabilities.

The patent extracts the data processing function from individual display units and consolidates it in a single timing controller. The timing controller centrally processes image data and generates synchronized output signals for multiple data drivers, eliminating the need for each display unit to perform independent data processing and synchronization operations.

The timing controller performs preliminary data processing and synchronization before distributing signals to multiple data drivers. By pre-processing image data and generating synchronized clock and data signals in advance, the system eliminates the need for additional data processing operations at each display unit, reducing overall processing time.
