Display Timing Controllers Eliminating Data Distributor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal displays require a quad-port LVDS transmission interface for higher resolutions and frequencies, leading to increased production costs and complex data transmission due to the need for a data distributor and two timing controllers.
Innovation Solution
A method and display configuration where two timing controllers receive and transmit non-adjacent pixel values, allowing source drivers to directly receive pixel values from both controllers, eliminating the need for a data distributor and simplifying data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a quad-port LVDS transmission interface is used for data transmission, then data transmission capability for higher resolution and frequency is improved, but device complexity and production cost increase due to requiring a data distributor and two timing controllers
Solution Approach 1:
The patent extracts and eliminates the data distributor component from the conventional quad-port LVDS transmission structure. By having two timing controllers directly transmit data to source drivers without an intermediate distributor, the system maintains high-speed data transmission capability while reducing device complexity and production cost.
Solution Approach 2:
The patent merges the functions of data distribution and timing control by having timing controllers directly connect to source drivers. This integration eliminates the separate data distributor component, simplifying the overall data transmission structure while maintaining the required data transmission performance for high resolution and frequency displays.
2Adaptability or versatility
If a data distributor is added to the data transmission system, then data distribution capability is improved, but production cost increases
Solution Approach 1:
The patent removes the data distributor component from the system while maintaining data distribution capability through direct connections between timing controllers and source drivers. This extraction eliminates the additional production cost associated with the distributor component.
Solution Approach 2:
The timing controllers are designed to perform both timing control and data distribution functions simultaneously. By making the timing controllers multi-functional, the system achieves the required data distribution capability without needing a separate data distributor component, thereby reducing production cost.
3Quantity of substance
If two timing controllers with dual-port LVDS interface are used, then data transmission capacity is improved, but data transmission complexity increases
Solution Approach 1:
The patent extracts the intermediate data distributor layer from the data transmission path. By enabling direct communication between the two timing controllers and source drivers, the system maintains the required data transmission capacity while significantly reducing data transmission complexity.

AI summary
A display is provided. The display includes a first timing controller, a second timing controller and drivers. The first timing controller receives and transmits a first portion of pixel values, in which the first portion of the pixel values includes the pixel values of at least two non-adjacent pixels. The second timing controller receives and transmits a second portion of the pixel values, in which the second portion of the pixel values includes the pixel values of at least two non-adjacent pixels. Each of the drivers receives respectively a part of the first portion of the pixel values transmitted by the first timing controller and a part of the second portion of the pixel values transmitted by the second timing controller. A method of transmitting image data in the display is also disclosed.
