Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional display driver panel devices use row-wise scanning to drive display elements, then the device complexity is reduced and ease of manufacture is improved, but the response speed becomes slow causing time delay between image capture and display
Solution Approach 1:
The display driver array is segmented into multiple independent display driver elements arranged in a matrix configuration, where each element can be independently controlled. This segmentation allows parallel driving of multiple pixels simultaneously, eliminating the sequential row-wise scanning approach and thereby significantly improving response speed while maintaining manageable device complexity through modular architecture
Solution Approach 2:
The patent transitions from one-dimensional row-wise scanning to two-dimensional matrix arrangement of display driver elements. By organizing pixels and their corresponding driver elements in a 2D grid structure, the system enables simultaneous addressing and driving of multiple pixels across different rows and columns, effectively increasing the dimensionality of signal transmission and improving overall response speed
2Loss of time
If row-wise scanning is used to input display driver signals, then the ease of operation is improved, but the time delay increases causing viewer vertigo
Solution Approach 1:
The matrix arrangement of display driver elements enables continuous and simultaneous driving action across multiple pixels rather than sequential row-wise scanning. Multiple display driver elements operate in parallel to update pixel information simultaneously, creating a continuous useful action that eliminates the temporal gaps and delays inherent in sequential scanning methods, thereby reducing time delay and preventing viewer vertigo
Solution Approach 2:
The patent implements preliminary action by pre-organizing display driver elements in a matrix structure with dedicated drive lines for each element before operation begins. This pre-established configuration allows immediate parallel driving of multiple pixels without the need for sequential row activation, effectively performing the driving action in advance across all pixels simultaneously and eliminating delays associated with sequential scanning
3Productivity
If conventional display driver devices are used, then the device complexity is manageable, but the productivity of image display is reduced due to slow response
Solution Approach 1:
The patent merges the image sensor array and display driver array into a single integrated panel device structure, where corresponding pixel sensor elements and display driver elements are positioned in direct alignment. This merging eliminates the need for separate signal transmission stages between independent sensor and display components, enabling direct coupling and simultaneous operation that significantly improves image display productivity while managing overall device complexity through integration
Data Source
AI summary
A display driver panel device and a method therefor are disclosed. The device includes: an image sensor array consisting of pixel sensor elements arranged in M rows and N columns; and a display driver array consisting of display driver elements arranged in M rows and N columns. Each of the display driver elements corresponds to a respective one of the pixel sensor elements. As such, first display input signals generated by the pixel sensor elements from a received external imaging radiation can be sent to the respective corresponding display driver elements. As a result, the display driver elements respond at the same time, resulting in an increased response speed of the display driver panel device.
