Timing Controller Embedded Data Driver for Display Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display (LCD) apparatuses face increased thickness and power consumption due to the presence of printed circuit boards and signal transmission between the timing controller and data driver.
Innovation Solution
Integration of a timing controller embedded data driver, which functions as both a timing controller and data driver, eliminating the need for a printed circuit board and reducing power consumption by embedding these components on the display panel substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a printed circuit board is used to mount the timing controller, then the timing controller can be properly positioned and connected, but the thickness of the display apparatus increases
Solution Approach 1:
The patent merges the timing controller and data driver into a single integrated component mounted directly on the display panel substrate. This consolidation eliminates the need for a separate printed circuit board, thereby reducing the overall thickness of the display apparatus while maintaining all necessary control functions.
Solution Approach 2:
The integrated component performs multiple functions simultaneously - it acts as both a timing controller and a data driver. This multi-functionality allows the system to eliminate the printed circuit board while still providing all necessary control capabilities, thus reducing thickness without sacrificing functionality.
2Use of energy by moving object
If signal transmission between timing controller and data driver is implemented, then data processing and display control can be achieved, but power consumption increases
Solution Approach 1:
By combining the timing controller and data driver into a single integrated component, the patent eliminates the need for signal transmission between separate components. This integration reduces power consumption by removing transmission losses while maintaining full data processing and display control capabilities through internal direct connectivity.
3Use of energy by stationary object
If timing controller and data driver are integrated on display panel substrate, then thickness and power consumption decrease, but manufacturing complexity increases
Solution Approach 1:
The patent integrates the timing controller and data driver on the display panel substrate using standard semiconductor manufacturing processes. This approach, while requiring additional manufacturing steps, leverages established industry techniques to achieve the integration, making the process feasible and scalable despite the increased complexity.

AI summary
A display panel includes a timing controller embedded data driver and a first data driver. The timing controller embedded data driver includes an image processing part and an internal data driving part. The image processing part generates a first data signal corresponding to a first display area and a second data signal corresponding to a second display area based on input image data. The internal data driving part generates a second data voltage based on the second data signal to output the second data voltage to the second display area. The first data driver is disposed at a first side of the timing controller embedded data driver. The first data driver receives the first data signal from the timing controller embedded data driver and generates a first data voltage based on the first data signal to output the first data voltage to the first display area.
