Data-Scan Integration Chip for Display Bezel Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display devices have a limited reduction in bezel width due to the separate placement of data drivers and scan drivers on opposite sides of the display panel, which restricts the miniaturization of the display panel and increases power consumption.
Innovation Solution
Implementing a data-scan integration chip that combines the functions of data and scan drivers on the same side of the display panel, sharing components such as level shifters and output buffers, to reduce the chip size and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If data driver and scan driver are placed on opposite sides of display panel, then each driver can be independently implemented, but bezel width cannot be reduced and chip size increases
Solution Approach 1:
The patent combines the data driver and scan driver into a single integrated chip located at one side of the display panel. This merging of previously separate driver functions into one unified device reduces the bezel width by eliminating the need for drivers on both sides, while maintaining independent operational capability through internal circuit architecture
Solution Approach 2:
The integrated driver chip performs multiple functions by incorporating both data driver circuits and scan driver circuits within a single device. This multi-functional design allows one chip to replace what previously required two separate chips, reducing overall device area and bezel width
2Use of energy by stationary object
If separate data driver and scan driver chips are used, then driver functions are independent, but power consumption increases
Solution Approach 1:
By merging the data driver and scan driver into a single integrated chip, the patent reduces power consumption through shared power supply circuits, common reference voltages, and reduced signal transmission paths. The unified architecture eliminates redundant circuitry that would exist in separate chips, thereby lowering overall energy consumption
3Area of stationary object
If data driver and scan driver are integrated on same chip, then chip size reduces, but circuit integration complexity increases
Solution Approach 1:
The integrated driver chip is designed with segmented functional blocks including separate data driver circuits, scan driver circuits, and control logic sections. This segmentation allows complex functions to be organized into manageable modules that can be independently designed and tested, reducing the practical complexity of integration while maintaining compact chip size
Solution Approach 2:
The patent employs multi-layer circuit board technology and three-dimensional circuit routing to accommodate the integrated driver circuits. By utilizing vertical space and multiple copper layers, the design fits complex circuitry into a smaller planar footprint, effectively reducing chip size while managing integration complexity through spatial organization
