Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a beam splitter lens is used in a three-dimensional display device, then three-dimensional image display is enabled, but image resolution is reduced and distortion occurs when displaying two-dimensional images
Solution Approach 1:
The patent applies dynamics by making the display system adaptable between two display modes (three-dimensional and two-dimensional) through a switching mechanism. The processing circuit dynamically switches between modes based on input signal type, allowing the same hardware to optimize for different display requirements without physical reconfiguration.
Solution Approach 2:
The patent changes parameters by adjusting pixel brightness values based on the display mode. When in two-dimensional mode, the processing circuit modifies brightness parameters of pixels according to a correction algorithm, transforming the image data to compensate for beam splitter lens effects and maintain image quality.
2Adaptability or versatility
If a beam splitter lens is used for three-dimensional display, then stereoscopic viewing is achieved, but image distortion occurs in two-dimensional display mode
Solution Approach 1:
The patent applies preliminary anti-action by pre-calculating and applying a correction algorithm to the image data before display. The processing circuit identifies when two-dimensional images are input and automatically adjusts brightness values in advance to counteract the distorting effects of the beam splitter lens, preventing distortion rather than correcting it after occurrence.
3Reliability
If the display panel is optimized for three-dimensional images, then stereoscopic display performance is improved, but two-dimensional image quality deteriorates
Solution Approach 1:
The patent applies universality by designing a multi-functional display system that can handle both three-dimensional and two-dimensional images effectively. The processing circuit incorporates a correction algorithm that activates specifically for two-dimensional mode, allowing the same display panel to maintain high quality across different display types without requiring separate optimization for each.
Data Source
AI summary
A switchable display system includes a display panel, an image source, a switching signal source, and a processing circuit. The display panel includes pixels containing a first pixel. The image source is used to provide image data. The switching signal source is used to provide a switching signal. The processing circuit is coupled to the display panel, an image source, and a switching signal source, stores a correction algorithm, and is used to drive the display panel to display a three-dimensional or two-dimensional image according to the switching signal. When the processing circuit drives the display panel to display the two-dimensional image according to the switching signal, the processing circuit switches a first brightness of the first pixel to a second brightness, which is determined based on brightness values in the image data of pixels of same color adjacent to the first pixel and weight values of the correction algorithm.
