Timing Controller Resolution Mismatch in Display Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses face increased manufacturing costs due to the requirement for a timing controller resolution that matches or exceeds the display panel resolution, leading to higher purchase costs.
Innovation Solution
A display apparatus with a timing controller of lower resolution than the display panel, utilizing N2 data drives and output video interfaces that transmit video data in a time-sharing manner to multiple input video interfaces, allowing for a cost-effective matching of lower resolution timing controllers with higher resolution display panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the timing controller resolution is set to match or exceed the display panel resolution, then the video data transmission quality is maintained, but the manufacturing cost and purchase cost increase
Solution Approach 1:
The patent segments the video data transmission process by dividing the display panel into multiple regions (first region and second region) with different resolution requirements. The timing controller outputs video data at a lower resolution (C*D) that is segmented into multiple lower-resolution frames, while the display panel displays these segmented frames at their full resolution (A*B). This segmentation allows the timing controller to operate at a lower resolution while still maintaining the required video data transmission quality for the high-resolution display panel.
Solution Approach 2:
The patent introduces a time dimension to resolve the resolution mismatch. Instead of transmitting video data at a single fixed resolution, the system transmits multiple lower-resolution frames in sequence over time, which are then displayed at the higher resolution of the display panel. This temporal multiplexing allows the timing controller to operate at a lower resolution (C*D) while the display panel presents the content at its native higher resolution (A*B), thereby reducing the timing controller's required resolution and associated costs.
2Ease of manufacture
If the timing controller resolution is reduced to lower costs, then the manufacturing cost decreases, but the video data transmission capability is compromised
Solution Approach 1:
The patent segments the video data transmission process by dividing the display panel into multiple regions (first region and second region) with different resolution requirements. The timing controller outputs video data at a lower resolution (C*D) that is segmented into multiple lower-resolution frames, while the display panel displays these segmented frames at their full resolution (A*B). This segmentation allows the timing controller to operate at a lower resolution while still maintaining the required video data transmission quality for the high-resolution display panel.
Solution Approach 2:
The patent ensures continuous video data transmission by outputting multiple lower-resolution frames in sequence. The timing controller continuously outputs video data at its lower resolution (C*D), and the display panel continuously displays these frames at the higher resolution (A*B). This continuous temporal multiplexing maintains the video data transmission capability without requiring the timing controller to operate at high resolution, thereby maintaining productivity while reducing costs.

AI summary
A display apparatus and a mobile terminal are provided. The display apparatus includes a display panel, N2 data drives, and a timing controller. Video data can be transmitted to a plurality of input video interfaces corresponding to the data drives in a time-sharing manner using one output video interface of the timing controller. Therefore, a timing controller with relatively low resolution can be matched with a display panel with relatively high resolution, thereby reducing overall costs of the display apparatus.
