Engineering Contradiction Analysis
1Weight of moving object
If a flexible display is folded, then it becomes lightweight and portable, but it becomes unusable for single-sided displays
Solution Approach 1:
The patent applies dimensionality change by transitioning from a single-sided display to a double-sided display. This allows the display to function in both unfolded and folded states by providing display surfaces on both sides of the flexible substrate, thereby maintaining usability while enabling portability through folding.
Solution Approach 2:
The patent implements dynamics by making the display orientation adaptive rather than fixed. The display controller dynamically adjusts the image data transmission order based on the detected folding state, allowing the display to adapt its functionality to different physical configurations (unfolded vs. folded states).
2Ease of operation
If image data transmission order is adjusted based on display position, then display functionality is maintained when folded, but system complexity increases
Solution Approach 1:
The patent employs feedback by using sensors to detect the folding state of the display and using this information to dynamically adjust the image data transmission order. The display controller receives feedback about the physical state and automatically modifies its operation accordingly, maintaining display functionality without requiring manual intervention.
Solution Approach 2:
The patent introduces an intermediary component (the display controller with transmission order determiner) that mediates between the fixed image data source and the variable display physical state. This intermediary processes the image data and adjusts its transmission order based on sensor feedback, shielding the user from the underlying complexity while maintaining functionality.

AI summary
A portable electronic device comprises a double-sided display including a first display side and a second display side formed on a side opposite the first display side; a direct memory access (DMA) controller configured to read first image data from a memory; at least one sensor configured to detect at least one of a position change of the double-sided display and a movement of a user's pupil and to output a detection signal; a status signal generator configured to interpret the detection signal output and to output a status signal; a transmission order determiner configured to receive the first image data from the DMA controller, to determine a transmission order of the first image data based on the status signal, and to output second image data corresponding to the determined transmission order; and a display driver integrated circuit (IC) configured to transmit the second image data to the display.
