Dynamic Light Shielding Member for Full-Screen Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices require drilling holes to accommodate electronic elements, limiting screen ratio and full-screen design due to the need for physical placement of components like cameras and sensors.
Innovation Solution
A display device with a light shielding member that opens and closes a light-transmitting channel between electronic elements and a second display region with higher transmittance, allowing electronic elements to be hidden when not in use, thus eliminating the need for physical holes and enhancing screen ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If electronic elements are placed in drilled holes in the display device, then the electronic elements can be accommodated, but the screen ratio is reduced and full-screen design is limited
Solution Approach 1:
The light shielding member is designed to be movable between an open position (allowing light transmission to the electronic element) and a closed position (blocking light and hiding the electronic element). This dynamic mechanism allows the display device to transition between states where the electronic element is visible or hidden, enabling full-screen design when closed and functional operation when open, thereby resolving the contradiction between screen ratio and device functionality
Solution Approach 2:
The display panel is divided into a first display region with normal light transmittance and a second display region with higher light transmittance corresponding to the electronic element position. This local differentiation in optical properties allows the electronic element to be integrated into the display structure without compromising the overall screen appearance, enabling full-screen design while accommodating electronic components
2Area of stationary object
If a light shielding member is introduced to hide the electronic element, then full-screen design is achieved, but the device structure becomes more complex
Solution Approach 1:
The light shielding member is integrated with the display panel structure, forming a unified component that serves both as part of the display assembly and as the shutter mechanism. This merging of functions reduces the need for separate independent components, thereby minimizing the increase in device complexity while achieving full-screen design
Solution Approach 2:
The light shielding member serves multiple functions: it acts as a shutter to hide the electronic element, serves as part of the display panel structure, and can be integrated with the pixel structure in the second display region. This multi-functionality reduces the overall component count and structural complexity while achieving the full-screen effect

Implementation Method 1
a light shielding member; wherein when the electronic element is in operation, the light shielding member is opened to open a light-transmitting channel between the electronic element and the second display region, and when the electronic element is not in operation, the light shielding member is closed to close the light-transmitting channel
Implementation Method 2
the light shielding member is made of electrochromic glass and disposed on the display panel

AI summary
The present invention provides a display device which includes a display panel, a light shielding member, and an electronic element. The display panel includes a first display region and a second display region disposed corresponding to the electronic element, and a light transmittance of the second display region is greater than a light transmittance of the first display region. When the electronic element is in operation, the light shielding member is opened to open a light-transmitting channel between the electronic element and the second display region. When the electronic element is not in operation, the light shielding member is closed to close the light-transmitting channel. When the electronic element needs to be used, the light shielding member is opened. When the electronic element is not needed, the light shielding member shield the electronic element to hide it.
