Hold-Type Display Variable Refresh Rate Motion Blur Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motion blur in display systems occurs due to incremental changes in image frames not capturing the true path of moving objects, leading to blurring, which existing technologies have not adequately addressed.
Innovation Solution
A system and method that dynamically switch between variable and fixed refresh rates and backlight modes to reduce motion blur, where the display operates with a variable refresh rate and constant backlight in one mode, and transitions to a fixed refresh rate with flashing backlight in another mode based on predefined conditions to minimize blurring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display operates with variable refresh rate and constant backlight, then it can handle unpredictable frame updates, but motion blur increases
Solution Approach 1:
The patent applies periodic action by implementing a fixed refresh rate mode where the backlight flashes at regular intervals synchronized with frame updates. This periodic illumination captures moving objects at consistent time points, eliminating motion blur while maintaining the ability to handle variable frame rates through the fixed timing reference.
Solution Approach 2:
The patent implements dynamics by allowing the display to dynamically switch between two operational modes: variable refresh rate with constant backlight and fixed refresh rate with flashing backlight. This dynamic adaptation enables the system to optimize for either frame update flexibility or motion blur reduction depending on current conditions.
2Object-affected harmful factors
If the display operates with fixed refresh rate and flashing backlight, then motion blur is reduced, but adaptability to unpredictable frame updates decreases
Solution Approach 1:
The patent implements dynamics by allowing the display to dynamically switch between two operational modes: variable refresh rate with constant backlight and fixed refresh rate with flashing backlight. This dynamic adaptation enables the system to optimize for either frame update flexibility or motion blur reduction depending on current conditions.
Solution Approach 2:
The patent applies segmentation by dividing the display operation into distinct modes with different characteristics. By segmenting the operational space into variable refresh mode and fixed refresh mode, the system can selectively apply the appropriate mode for each situation, combining the benefits of both approaches.
3Illumination intensity
If the backlight is activated for entire duration of image frame display, then light output is consistent, but motion blur increases
Solution Approach 1:
The patent applies periodic action by implementing a fixed refresh rate mode where the backlight flashes at regular intervals synchronized with frame updates. This periodic illumination captures moving objects at consistent time points, eliminating motion blur while maintaining the ability to handle variable frame rates through the fixed timing reference.
Solution Approach 2:
The patent implements dynamics by allowing the display to dynamically switch between two operational modes: variable refresh rate with constant backlight and fixed refresh rate with flashing backlight. This dynamic adaptation enables the system to optimize for either frame update flexibility or motion blur reduction depending on current conditions.
4Object-affected harmful factors
If the backlight is flashed for each image frame, then motion blur is reduced, but energy consumption increases
Solution Approach 1:
The patent applies periodic action by implementing a fixed refresh rate mode where the backlight flashes at regular intervals synchronized with frame updates. This periodic illumination captures moving objects at consistent time points, eliminating motion blur while maintaining the ability to handle variable frame rates through the fixed timing reference.
Solution Approach 2:
The patent implements dynamics by allowing the display to dynamically switch between two operational modes: variable refresh rate with constant backlight and fixed refresh rate with flashing backlight. This dynamic adaptation enables the system to optimize for either frame update flexibility or motion blur reduction depending on current conditions.

AI summary
A system, method, and computer program product are provided for combining low motion blur and variable refresh rate in a display. In one embodiment, a hold-type display is operated in a first mode of operation where the hold-type display is dynamically refreshed such that the hold type display handles updates to image frames at unpredictable times and where for each of the image frames a backlight of the hold-type display is activated for an entire duration of display of the image frame. Additionally, it is determined that at least one predefined condition has been met. Further, in response to the determination, the hold-type display is operated in a second mode of operation where the hold-type display is statically refreshed such that the hold-type display handles updates to image frames at regular intervals and where for each of the image frames the backlight of the hold-type display is flashed.
