Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital video presentations suffer from image blurriness and distortion due to slower response times in display devices, which fail to keep pace with the refresh rate of video pixel information, leading to an unpleasant user experience.
Innovation Solution
A digital video display response time compensation system and method that adjusts pixel illumination in real-time using an iterative test pattern response time compensation value determination process, allowing for calibration of pixel values to match the desired illumination levels, thereby reducing lag and blurriness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the refresh rate of video pixel information is increased, then the clarity and timeliness of image presentation is improved, but the display device response time becomes insufficient leading to blurriness and distortion
Solution Approach 1:
The system performs preliminary action by adjusting pixel illumination values before the display device renders the image. By pre-calculating and pre-adjusting the pixel data to account for the display's response characteristics, the system compensates for the slow response time in advance, ensuring that the final displayed image is clear and free from blurriness even at high refresh rates
Solution Approach 2:
The system changes parameters by dynamically adjusting pixel illumination values based on the display device's response time characteristics. The illumination adjustment process modifies the brightness and timing parameters of pixel data to optimize the balance between refresh rate and image clarity, allowing the display to maintain high refresh rates without sacrificing image quality
2Manufacturing precision
If the response time of display device is increased to match refresh rate, then image blurriness is reduced, but the time lag between receiving pixel information and reaching illumination level increases
Solution Approach 1:
By performing illumination adjustments in advance before the display rendering process, the system eliminates the need to increase response time. The pre-adjustment of pixel illumination values ensures that when the display device does respond, it does so with optimized parameters that reduce both blurriness and time lag simultaneously
3Manufacturing precision
If pixel illumination is adjusted in real-time, then image sharpness and clarity are improved, but the complexity of the display system increases
Solution Approach 1:
The system replaces complex hardware modifications with software-based processing. By implementing the illumination adjustment process through digital signal processing and algorithms rather than mechanical or hardware changes, the system achieves real-time pixel illumination adjustment while keeping the physical display device relatively simple

AI summary
A digital video display response time compensation system and method are presented. A digital video display response time compensation system and method are utilized to direct adjustments in a display presentation. A test pattern response time compensation value determination process for establishing appropriate adjustment levels for a display is performed. A test pattern is displayed; user input on compensation to the test pattern display is received; pixel value calibration settings are determined based upon the user input; and the test pattern display appearance is altered based upon the pixel value calibration settings. After the appropriate pixel illumination adjustment values are establish a pixel value is received. The pixel value is adjusted in accordance with the response time compensation value and a response time compensated pixel value is output.
