Terminal Display Method Using Half-Frame Brightness Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Virtual Reality (VR) technology, low display frame rates on terminals can cause user dizziness, and increasing frame rates requires special chips, increasing costs and development time.
Innovation Solution
A terminal display method and apparatus that improves screen smoothness by controlling the ON/OFF of screen brightness and dividing each frame into left and right half-frames for separate rendering, utilizing the fast response speed of AMOLED screens to clear afterglow effects without additional hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the display frame rate of the terminal is increased to improve user visual effect, then the user experience is improved, but special chips are required which increase cost and development cycle
Solution Approach 1:
The patent divides each display frame into two half-frames (left and right), displaying them separately with the screen brightness turned on and off alternately. This segmentation allows the system to achieve high frame rates through software control rather than requiring special high-performance chips, thereby improving display smoothness while avoiding increased device complexity and cost.
2Loss of time
If the display frame rate is increased to reduce visual delay, then the display effect is improved, but the cost and development cycle increase due to special chip requirements
Solution Approach 1:
The patent employs periodic switching of screen brightness synchronized with the display of left and right half-frames. By turning the screen brightness on during left half-frame display and off during right half-frame display (or vice versa), the system creates a periodic action that reduces visual persistence and afterglow effects, thereby reducing perceived visual delay without requiring special chips.
3Device complexity
If standard screens are used without special chips, then cost is reduced, but the display frame rate is not high enough causing user dizziness
Solution Approach 1:
The patent changes the display parameters by dividing frames into half-frames and controlling screen brightness timing, effectively doubling the perceived frame rate from standard rates (e.g., 60Hz) to higher rates (e.g., 90Hz or 120Hz equivalent). This parameter change allows standard screens to achieve high frame rates without requiring special high-performance chips, thus maintaining simplicity while improving display performance.

AI summary
Provided is a terminal display method, said method comprising: displaying a picture corresponding to left half-frame data of a current data frame, and starting a first timer; when the count time of said first timer ends, closing the screen brightness; rendering a picture corresponding to the right half-frame data of said current data frame starting a second timer; when the count time of said second timer ends, opening the screen brightness, displaying the picture corresponding to the right half-frame data, and simultaneously starting the first timer; and when the count time of the first timer ends, closing the screen brightness. The present disclosure also provides a terminal display apparatus.
