Display Frame Interpolation for 60 Hz to 120 Hz Upscaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face issues with blurring and judder when displaying high-quality content with frame rates higher than 60 Hz, and upgrading hardware to support higher frame rates increases manufacturing costs.
Innovation Solution
A display apparatus and control method that adjusts the frame rate and resolution of content by generating interpolated frames based on motion information, allowing the display panel to operate at multiple frame rates without altering its structure, using a processor to control the display panel to output content at higher frame rates by simultaneously driving adjacent gate lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the operating frequency of the display apparatus is increased to 120 Hz or more to smoothly reproduce high frame rate content, then the frame rate compatibility is improved, but the manufacturing cost is excessively increased
Solution Approach 1:
The patent changes the operating parameters of the display apparatus dynamically. It operates at 60 Hz for standard content and switches to 120 Hz when high frame rate content is detected, allowing the display to adapt to different content requirements without permanently upgrading hardware specifications, thereby reducing manufacturing costs while maintaining frame rate compatibility when needed
Solution Approach 2:
The display apparatus employs dynamic frequency switching capability, transitioning between 60 Hz and 120 Hz operating modes based on content requirements. This dynamic adaptation allows the system to achieve high frame rate compatibility only when necessary, avoiding the need for continuous high-frequency operation and the associated increased manufacturing costs
2Productivity
If the frame rate of 60 Hz content is displayed on a 120 Hz display apparatus, then the operating frequency is improved, but blurring and judder are greatly generated
Solution Approach 1:
The patent introduces frame rate conversion as an intermediary process between the 60 Hz content source and the 120 Hz display panel. By generating interpolated frames through frame rate conversion, the system mediates the mismatch between content frame rate and display refresh rate, eliminating blurring and judder while maintaining high frame rate operation
Solution Approach 2:
The display apparatus performs preliminary frame rate conversion and image processing before displaying content on the 120 Hz panel. By pre-processing the 60 Hz content to generate appropriate intermediate frames, the system prepares the image data in advance to match the higher refresh rate, preventing blurring and judder from occurring during display

AI summary
A display apparatus is disclosed. The display apparatus comprises: a display panel which can output a first resolution content at a first frame rate; a communication interface comprising communication circuitry; and a processor which when a first resolution content is received through the communication interface and the frame rate of the content is the first frame rate, is configured to: adjust the resolution of the received content to a second resolution, generate an interpolated frame for the second resolution content, and control the display panel to output the second resolution content including the interpolated frame at a second frame rate greater than the first frame rate.
