Display Screen With Vacant Region For Improved Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices with front cameras cannot achieve full-screen display due to the camera being installed in a non-display region, resulting in a poor imaging effect as the display screen partially blocks and absorbs light.
Innovation Solution
A display screen with a first and second display region, where the second region has a vacant area without isolation pillars, allowing metal spirals or prisms in the anode layer to form surface plasmon resonance structures, enabling light to pass through and improve imaging by enhancing antireflection and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If isolation pillars are formed in the second display region, then the display structure is complete and reliable, but light transmission is blocked and imaging effect deteriorates
Solution Approach 1:
The second display region is segmented into two types of areas: first display areas with isolation pillars for reliable display structure, and second display areas without isolation pillars for improved light transmission. This segmentation allows different regions to serve different functions, resolving the contradiction between structural reliability and light transmission.
Solution Approach 2:
Different regions within the second display region are given different structural qualities: some areas have isolation pillars while others do not. This local differentiation enables the display screen to simultaneously achieve structural reliability in display areas and optimal light transmission in imaging areas.
2Device complexity
If the pixel defining layer is continuous, then the display structure is simple and reliable, but light passing through the second display region is blocked and absorbed
Solution Approach 1:
The pixel defining layer is segmented into continuous regions in the first display region and discontinuous regions with openings in the second display region. This segmentation allows the pixel defining layer to maintain structural simplicity where needed while enabling light transmission where required for imaging.
Solution Approach 2:
The isolation pillar structure is extracted (removed) from the second display region, creating vacant regions where light can pass through unobstructed. This extraction eliminates the blocking and absorbing of light while maintaining the overall display function through the remaining structural elements.
3Area of stationary object
If full-screen display is implemented, then the display area is maximized, but the camera cannot be accommodated and imaging function is lost
Solution Approach 1:
The second display region is designed with multi-functionality: it can function as a display area when isolation pillars are present, and as an imaging area when isolation pillars are removed and openings are created. This universality allows the same region to serve both display and camera imaging functions, enabling full-screen display while maintaining imaging capability.
Solution Approach 2:
The second display region is designed to be dynamically configurable - the isolation pillars can be selectively removed and openings can be formed to transition between display mode and imaging mode. This dynamic adaptability allows the display screen to accommodate both full-screen display and camera imaging functions.

Function Achieved in This Case
The solution allows for full-screen display and improved imaging by ensuring light passes through the second display region without obstruction, enhancing the light transmission and reducing reflection, thereby improving the overall imaging effect.

AI summary
A display screen and an electronic device are disclosed. The display screen has a first display region and a second display region. The display screen includes an anode layer, a pixel defining layer disposed on the anode layer, a number of isolation pillars disposed on the pixel defining layer, and a driving layer group. The pixel defining layer and the isolation pillars form a sub-pixel isolation structure, and the isolation pillars, the pixel defining layer, the driving layer group, and the anode layer are disposed in the first display region and the second display region. The second display region has a vacant region corresponding to a region forming the isolation pillar and without the isolation pillar formed therein, and the pixel defining layer is provided with an opening under the vacant region.
