Timing Control Register for Simultaneous Picture Splicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screen display technologies often result in incomplete information display due to new pictures overwriting or blocking original pictures, with updates being paused or delayed.
Innovation Solution
A display method involving a timing control register that reduces the original resolution to a preset resolution, splices the original and new pictures to maintain the original resolution, and updates both pictures simultaneously, ensuring they are displayed without overlapping or blocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If additional picture display overlays original pictures, then information display completeness is improved, but picture update timeliness deteriorates
Solution Approach 1:
The display interface is segmented into multiple layers: the original picture layer and the additional picture layer (information box). The timing control register separately processes update commands for each layer, allowing the original picture to be updated in the background while the information box is displayed on top. This segmentation enables independent update timing for each layer, resolving the contradiction between complete information display and timely picture updates.
2Productivity
If new pictures overwrite original pictures, then display efficiency is improved, but information completeness deteriorates
Solution Approach 1:
The solution transitions from a single-layer display to a multi-layer display structure. The additional picture (information box) is displayed in a separate layer above the original picture, rather than replacing it. This dimensional change allows both pictures to coexist simultaneously, maintaining information completeness while preserving display efficiency through layered rendering.
3Speed
If picture resolution is reduced, then processing speed is improved, but display quality deteriorates
Solution Approach 1:
The timing control register performs partial processing on the original picture by generating a lower-resolution version for background processing while maintaining the full-resolution original picture intact. The lower-resolution version is used only for timing synchronization purposes, while the final displayed image combines the full-resolution original picture with the additional picture overlay, thus achieving processing speed improvement without sacrificing display quality.

AI summary
The present disclosure provides a display method for a picture, a timing control register, and an electronic device. The method includes: in a case of receiving a command for displaying a first picture, reducing, by a timing control register, an original resolution to a preset resolution, and the first picture is a picture needing to be displayed at the same time as an original picture of a screen; sending the preset resolution to a display card, so that the display card outputs a picture with the preset resolution to obtain a second picture, and sends the second picture to the timing control register; and receiving the first picture and the second picture, and splicing the first picture with the second picture into a picture with the original resolution to obtain a target picture, and sending the target picture to the screen for displaying.
