Single Flash Memory for Display Timing Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display systems waste flash memory capacity by having separate flash memory chips on control and source circuit boards, leading to increased production costs.
Innovation Solution
A driving system for a display panel with a single flash memory chip on a first circuit board storing both basic configuration data for the timing controller and adjustment data, connected to a timing controller on a second circuit board, which uses a serial interface to read and apply these data for image adjustment and correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate flash memory chips are equipped on control circuit board and source circuit board, then the timing controller can read basic configuration software and adjustment data separately, but waste of flash memory capacity occurs and production cost increases
Solution Approach 1:
The patent merges the storage function of two separate flash memory chips into a single flash memory chip located on the source circuit board. This single chip stores both the basic configuration software needed by the timing controller and the adjustment data for image quality optimization, thereby reducing component quantity while maintaining all necessary functions.
Solution Approach 2:
The single flash memory chip on the source circuit board is designed to serve multiple purposes: storing adjustment data for the display panel, storing basic configuration software for the timing controller, and enabling both image quality optimization and timing controller operation. This multi-functional design eliminates the need for separate dedicated storage devices.
2Ease of manufacture
If separate flash memory chips are used on control and source circuit boards, then data can be stored and accessed independently, but production cost increases due to increased component quantity
Solution Approach 1:
The patent combines the storage functions into a single flash memory chip on the source circuit board, reducing the total number of components and simplifying the overall system configuration. This merging approach decreases device complexity while maintaining the capability to store and access both basic configuration software and adjustment data.

AI summary
A driving system and a driving method of a display panel are provided. A flash memory is disposed in a first circuit board of the driving system, and a timing controller is disposed in a second circuit board of the driving system. In this way, only one flash memory is needed to store basic configuration data of the timing controller and adjustment data of the display panel, and a number of flash memory is decreased in comparison with two flash memories required in conventional technology. Flash memory capacity is reasonably used, preventing a waste of flash memory capacity while saving production cost.
