Display Apparatus Resolution Scaling for High-Frame-Rate Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses struggle to playback high frame rate content without significantly increasing manufacturing costs or degrading image quality, as they often operate at lower frequencies than the content frame rate, leading to frame omission and reduced scanning times.
Innovation Solution
A display apparatus and control method that adjusts content resolution and frame rate to match the display panel's capabilities, allowing concurrent driving of adjacent gate lines and reducing display time by half, maintaining image quality while operating at lower frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the operating frequency of the display apparatus is increased to 120 Hz or more to playback high frame rate content, then the frame rate of the content can be displayed as is, but the manufacturing costs rise excessively
Solution Approach 1:
The patent dynamically adjusts the operating frequency of the display apparatus based on the frame rate of the input content. When high frame rate content (120 Hz or more) is detected, the system increases the operating frequency to match, and when standard content is input, it reduces to normal operating frequency. This dynamic adaptation allows the display to handle high frame rate content without permanently maintaining high-frequency hardware specifications, thereby reducing manufacturing costs while preserving playback quality when needed.
2Loss of time
If the scanning time of one pixel line is significantly reduced to playback high quality content at high frame rate, then the response characteristic improves, but the manufacturing costs increase excessively
Solution Approach 1:
The patent implements dynamic scanning time adjustment by detecting the frame rate of input content and adapting the pixel line scanning time accordingly. For high frame rate content, the system reduces scanning time to meet the faster refresh requirements, and for standard content, it uses normal scanning times. This allows the display to achieve fast response characteristics only when necessary, avoiding the need for permanently optimized (and expensive) hardware designed for maximum speed.
3Reliability
If the operating frequency is increased to display content without frame omission, then the content playback smoothness improves, but the manufacturing costs rise
Solution Approach 1:
The patent dynamically adjusts the operating frequency to match the frame rate of the input content, ensuring smooth playback without frame omission only when high frame rate content is detected. When standard frame rate content is input, the system operates at normal frequency, avoiding the need for expensive high-frequency hardware while maintaining playback quality when needed.
Solution Approach 2:
The patent changes the operating frequency parameter of the display apparatus based on the detected frame rate of input content. By adjusting this key parameter dynamically, the system achieves smooth content playback without frame omission when required, while avoiding the permanent hardware upgrades that would be necessary to maintain high frequency continuously, thereby controlling manufacturing costs.

AI summary
A display apparatus is disclosed. The display apparatus includes a display panel configured to drive a frame of a first resolution at a first frame rate, a communication interface comprising circuitry configured to receive content, and a processor configured to, based on a frame rate of the received content being greater than the first frame rate, adjust the received content to a second resolution, and to control the display panel to display a content of the second resolution at a second frame rate, the second frame rate being greater than the first frame rate.
