Always-On Clock Display Layering for Richer Visual Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current always-on-display (AOD) effects for electronic devices, such as smartphones and tablets, are monotonous, failing to provide a richer visual experience when displaying digital clocks, as they typically present a simple front-to-back relationship between the clock digits and background or foreground patterns.
Innovation Solution
An electronic device sequentially superimposes multiple images to generate a to-be-displayed image, where the first part of a target control is displayed behind the clock digits and the second part is displayed in front, creating a more intricate visual effect by overlapping the control with the clock digits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple front-to-back relationship is used between digital clock and pattern, then the display structure is simple, but the visual effect is monotonous
Solution Approach 1:
The patent divides the target control into a first part and a second part, displaying the first part behind the digital clock and the second part in front of the digital clock. This segmentation creates a complex visual effect with layered depth while maintaining relatively simple individual image components, resolving the contradiction between structural simplicity and visual richness.
Solution Approach 2:
The patent introduces a new dimensional layer by superimposing multiple images (first image with first part, third image with digital clock, second image with second part) to create a to-be-displayed image with depth layers. This adds spatial dimensionality to the display, transforming a flat front-to-back relationship into a multi-layered visual structure that enhances visual effect richness.
2Illumination intensity
If the entire display area is illuminated, then the display effect is comprehensive, but power consumption increases and screen burning occurs
Solution Approach 1:
The patent applies local quality by illuminating only the specific areas where the target control is located (first part and second part regions) rather than the entire display area. The to-be-displayed image is generated with precise spatial localization, so only relevant regions consume power and emit light, reducing overall power consumption and preventing screen burning while maintaining comprehensive display effect in the active areas.

AI summary
Embodiments of this application provide a time display method and an electronic device. The method is applied to an electronic device with a display, and the method includes: The electronic device obtains a first image, a second image, and a third image, where the first image includes a first part of a target control, the second image includes a second part of the target control, and the third image includes a digital clock. The electronic device sequentially superimposes the first image, the third image, and the second image to generate a to-be-displayed image, where the first part and the second part of the target control form the target control, and the target control overlaps at least one digit of the digital clock. The electronic device displays the to-be-displayed image when the display is in an always-on-display state.
