Variable Resolution Display Using Shift Register Data Duplication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack flexibility and precision in managing resolutions and data flow, leading to inefficient energy consumption and limited range of attainable resolutions due to the need for dedicated decoders and inflexible zone positioning in multi-resolution displays.
Innovation Solution
A display device with a selection circuit that uses shift registers and switches controlled by configuration words to duplicate pixel data across multiple lines or columns, allowing for flexible grouping and positioning of macropixels, thereby reducing data stream complexity and preserving low resolutions with improved precision.

Engineering Contradiction Analysis
1Quantity of substance
If conventional compression systems with dedicated decoders are used, then data flow is reduced, but energy consumption increases due to the decoder component
Solution Approach 1:
The invention extracts the decoding function from a separate dedicated decoder component and integrates it directly into the display device's pixel array. This eliminates the need for an external decoder while maintaining data compression benefits, thereby reducing energy consumption associated with separate decoding hardware.
Solution Approach 2:
The display device performs its own decoding operation through integrated logic within the pixel array, rather than relying on an external decoder. The display device self-services the decompression function, eliminating the energy overhead of a separate decoder component while maintaining the ability to handle compressed data formats.
2Quantity of substance
If uniform resolution reduction is implemented, then data flow is reduced, but flexibility and precision in positioning different resolution zones are limited
Solution Approach 1:
The invention applies different resolution characteristics to different local zones within the display. Each zone can be independently configured with its own resolution level, allowing high-resolution regions to be positioned precisely where needed while other regions use lower resolutions. This local differentiation enables flexible positioning of multiple resolution zones without requiring uniform resolution reduction across the entire display.
Solution Approach 2:
The invention implements dynamic control over resolution configuration through programmable logic that can adjust zone positions and resolutions in real-time. This dynamic capability allows the display to adapt resolution settings based on content requirements and user preferences, providing flexibility in positioning different resolution zones that uniform reduction schemes cannot achieve.
3Quantity of substance
If more lines are selected simultaneously to reduce resolution, then data flow is reduced, but precision in positioning and range of attainable resolutions decrease
Solution Approach 1:
The invention segments the pixel array into independently controllable groups or zones, where each segment can be assigned to receive data from a specific number of source lines. This segmentation allows precise control over which lines are combined for each zone, enabling fine-grained adjustment of resolution levels and accurate positioning of resolution boundaries without the precision loss associated with uniform line selection across the entire display.
