Innovation Solution
A display device architecture that utilizes a timing controller to transfer line configuration signals via a low-speed driving line, improving the throughput and bandwidth of high-speed driving lines, allowing for efficient data transfer and reduced power consumption by optimizing the transfer of image and frame configuration signals between high-speed and low-speed driving lines.

Engineering Contradiction Analysis
1Productivity
If the transfer rate of drive integrated circuits is increased to meet high-resolution and high-frame-rate display demands, then display performance is improved, but physical limitations and interface constraints prevent further improvement
Solution Approach 1:
The patent segments the driving lines into two distinct types: high-speed driving lines for image signals and low-speed driving lines for configuration signals. This segmentation allows each type of signal to be transmitted through the most appropriate channel, enabling the high-speed lines to operate at optimal speeds for image data while low-speed lines handle configuration data, thereby resolving the bottleneck in overall transfer rate improvement.
Solution Approach 2:
The patent introduces low-speed driving lines as intermediary channels specifically for transmitting configuration signals. This intermediary approach separates configuration signal transmission from image signal transmission, allowing the high-speed driving lines to maintain their high transfer rates for image data while the low-speed lines handle the less time-critical configuration data, thus overcoming the physical limitations of unified high-speed transmission.
2Quantity of substance
If more data is transmitted through high-speed driving lines to achieve high resolution, then bandwidth is increased, but power consumption increases due to higher transfer rates
Solution Approach 1:
The patent segments the data transmission workload by routing image signals through high-speed driving lines and configuration signals through low-speed driving lines. This segmentation ensures that only the necessary image data is transmitted at high speeds, while configuration data is transmitted at lower speeds, thereby reducing overall power consumption while maintaining the required data throughput for high-resolution displays.
Solution Approach 2:
The patent changes the transmission speed parameter for different types of signals. Configuration signals are transmitted at lower speeds through dedicated low-speed lines, while image signals maintain high transmission speeds. This parameter differentiation reduces the energy required for transmitting configuration data without compromising the quality or resolution of the displayed image.
3Reliability
If configuration signals are transmitted through high-speed driving lines, then signal integrity is maintained, but throughput of the high-speed lines is reduced
Solution Approach 1:
The patent segments the signal transmission paths by dedicating low-speed driving lines exclusively to configuration signals and high-speed driving lines exclusively to image signals. This segmentation ensures that configuration signals are transmitted reliably through the low-speed lines without interfering with the high-speed image signal transmission, thereby maintaining both signal integrity and maximum throughput for image data.
Solution Approach 2:
The patent uses low-speed driving lines as intermediary channels for configuration signals, separating them from the high-speed image signal paths. This intermediary approach allows configuration signals to be transmitted with sufficient reliability through the low-speed lines while the high-speed lines maintain their full throughput capacity for image data, eliminating the trade-off between signal integrity and throughput.
