Display Panel Segmentation for Always-On Mode Power and Aesthetics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with always-on modes face challenges in aesthetics and user recognition due to overlapping camera or sensor modules, which reduce the visibility of displayed information, and require efficient power management between normal and low power modes.
Innovation Solution
A display device design featuring a display panel with a functional area not displaying images and a surrounding display area that shows images in always-on mode, using a lens-based first functional module to provide status information through a combination of images and boundaries, and a light emitting element layer for efficient power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera module or sensor module is disposed in the display area, then the display device can provide additional functionality, but the user recognition of information displayed in the display area is reduced
Solution Approach 1:
The display area is segmented into a first display area and a second display area, with the camera module disposed in the first display area and information displayed in the second display area. This spatial segmentation allows both the camera functionality and information display to coexist without interfering with each other, resolving the contradiction between added functionality and user recognition.
2Area of stationary object
If the display area is increased, then the display device can show more information, but camera or sensor modules in the display area reduce user recognition of the information
Solution Approach 1:
The display area is divided into two distinct regions: a first display area containing the camera module and a second display area for information display. This segmentation allows the overall display area to be maximized while ensuring that the information display region remains free from obstructions, maintaining high user recognition.
3Ease of operation
If the display device is in always-on mode to reduce user inconvenience, then information is continuously displayed, but power consumption increases
Solution Approach 1:
In the always-on mode, only a portion of the display device (the second display area) is activated to display information, while other portions remain inactive. This local activation approach allows the device to provide continuous information display for user convenience while minimizing overall power consumption by keeping unnecessary display regions dormant.
4Adaptability or versatility
If camera or sensor modules are disposed in the display area, then additional functionality is provided, but aesthetics of the display device are reduced
Solution Approach 1:
The display area is segmented into a first display area for the camera module and a second display area for information display. This segmentation strategically positions the camera module in a dedicated region, preventing it from obscuring the information display area and thereby maintaining the aesthetic appearance of the display device while still providing additional functionality.

AI summary
A display device includes: a display panel including: a functional area defined by an opening formed in the display panel; and a display area defined as an area where a plurality of light emitting elements are arranged, surrounding the functional area; and a functional module including a lens disposed overlapping the functional area, wherein only some of the plurality of light emitting elements of the display panel are configured to emit light in a low power mode, and wherein all of the plurality of light emitting elements are configured to emit light in a general mode; and wherein the display device is configured to, in the low power mode, provide a predetermined information to a user formed by the boundary between the functional area and the display area and an image formed by light emission of the some of the plurality of light emitting elements.
