Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face inefficiencies in image data movement, leading to increased power consumption and time-related losses, particularly in applications requiring rapid image shifts.
Innovation Solution
A display device with pixel-embedded memory and shift registers that allow image data to be stored and shifted between adjacent pixels based on control signals, minimizing power consumption and time loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If image data is moved between pixels using conventional methods, then image data can be transferred, but power consumption increases and time loss occurs
Solution Approach 1:
The patent merges the data storage function and data transfer function into a single integrated system. The pixel-embedded memory stores image data, and the same memory structure performs shifting operations to transfer data between pixels, eliminating the need for separate transfer mechanisms and reducing power consumption while maintaining transfer efficiency
Solution Approach 2:
The patent introduces shift registers as intermediary components that facilitate efficient data transfer between pixels. These shift registers act as mediators that can hold data temporarily and transfer it bit-by-bit to adjacent pixels, enabling controlled data movement without direct pixel-to-pixel communication, thus reducing power consumption and time loss
2Adaptability or versatility
If image data shifting is implemented in displays, then versatility is improved, but device complexity increases
Solution Approach 1:
The pixel-embedded memory is designed to serve multiple functions: storing image data during normal operation and performing shifting operations for data transfer. This multi-functional design enables the display to support various applications (such as image stabilization, panning, and special effects) without requiring separate dedicated circuits for each function, thus improving versatility while controlling complexity
Solution Approach 2:
The patent segments the data transfer operation into bit-by-bit shifting through multiple clock cycles. Instead of transferring multi-bit data in a single complex operation, the shift registers transfer data one bit at a time, simplifying the circuit design at each pixel while achieving the overall data transfer goal, thus managing device complexity effectively

AI summary
Disclosed are a device and a method for supporting image data movement within a display. The display device may include a controller configured to control data writing, driving of a light-emitting element, and data movement, and a plurality of pixels each including a pixel-embedded memory configured to store image data represented by a multi-bit value. Each of the plurality of pixels may be configured to store image data in the pixel-embedded memory during a data write time interval and shift the image data stored in the pixel-embedded memory to one of upper, lower, left, or right adjacent pixels based on a control signal input from the controller during a data movement time interval.
