Solution Overview
Problem
Current organic light emitting display devices can only display either 2D or 3D images, requiring separate devices for each type, which is inconvenient for watching both 2D and 3D content simultaneously.
Innovation Solution
An organic light emitting display device with a data processor that classifies incoming data as 2D or 3D, producing additional frame data as needed, and a timing controller that manages pixel emission states to display both 2D and 3D images on a single panel by controlling power drivers and scan signals, synchronized with shutter glasses for proper viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate display devices are used for 2D and 3D images, then image display capability is improved, but device complexity and user convenience deteriorate
Solution Approach 1:
The display device is designed to perform multiple functions by displaying both 2D and 3D images on a single panel. The timing controller and data processor enable the same display hardware to switch between different display modes, eliminating the need for separate 2D and 3D display devices and improving user convenience while maintaining versatility
Solution Approach 2:
The display device dynamically switches between 2D and 3D display modes based on input signal type. The timing controller detects whether the input is 2D or 3D content and adjusts the scanning and emission timing accordingly, allowing the same hardware to adapt to different display requirements without physical reconfiguration
2Use of energy by moving object
If pixels remain in emission state during scan period, then power consumption is reduced, but image quality and synchronization deteriorate
Solution Approach 1:
The display employs periodic emission control where pixels are turned off during the scan period and activated during the emission period. This periodic switching synchronized with the scan timing ensures that pixels do not emit light during data writing, preventing display artifacts and maintaining image quality while managing power consumption through controlled emission cycles
