Intelligence Light Adjustment Layer for Display Visual Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display screens experience poor visual coordination between the display area and outer frame when not in operation, as the display area remains dark and black, causing visual abruptness.
Innovation Solution
A display device with a stacked structure comprising an intelligence light adjustment layer, a light-transmitting reflective layer, and a control unit, where the intelligence light adjustment layer changes states based on power application to match the outer frame's color when the display is off, using a polymer dispersed liquid crystal (PDLC) and a light-transmitting reflective layer to conceal the display module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the display area remains dark when not in operation, then the display module can be simply structured without additional components, but the visual coordination between the display area and outer frame deteriorates
Solution Approach 1:
The patent applies a light-adjusting layer that changes its optical properties between transparent and opaque states. When the display is off, the layer becomes opaque and matches the color of the outer frame (e.g., white), eliminating visual abruptness. When the display is on, the layer becomes transparent to allow display images to be viewed. This color/optical state change directly resolves the contradiction between simple structure and visual coordination.
Solution Approach 2:
The light-adjusting layer dynamically transitions between transparent and opaque states based on the operational state of the display module. This dynamic adjustment allows the display area to adapt its appearance to match the outer frame when inactive, while maintaining full visibility when active, thus resolving the visual coordination issue without permanently complicating the display module structure.
2Illumination intensity
If a light-adjusting layer is added to improve visual coordination, then the visual coordination between display area and outer frame improves, but the device complexity increases
Solution Approach 1:
The patent combines the light-adjusting layer with the display module in a stacked structure where the layer is integrated between the display module and the outer frame. This merging approach allows the light-adjusting function to be incorporated into the existing display module architecture rather than adding a separate, complex external system, thus improving visual coordination while minimizing the increase in overall device complexity.
Solution Approach 2:
The light-adjusting layer serves multiple functions: it adjusts light transmission to match the outer frame color when the display is off, and becomes transparent to display images when the display is on. This multi-functionality eliminates the need for separate components for each function, thereby improving visual coordination without proportionally increasing device complexity.
3Illumination intensity
If the intelligence light adjustment layer matches the outer frame color when off, then visual coordination improves, but the manufacturing precision requirements increase
Solution Approach 1:
The patent utilizes the ability of the light-adjusting layer to change its optical parameters (transparency and color appearance) in response to electrical power application. By controlling the electrical state of the layer, the color and transparency can be precisely adjusted to match the outer frame when off, and to become transparent when on. This parameter control through electrical means reduces the need for high manufacturing precision in achieving color consistency, as the color matching is dynamically controlled rather than statically manufactured.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Improves visual coordination by ensuring the outer frame and display area have the same color when not in operation, reducing visual abruptness and enhancing user satisfaction.
Implementation Method 1
the intelligence light adjustment layer includes a polymer dispersed liquid crystal (PDLC). When the electrical power is not applied to the intelligence light adjustment layer, the outer frame and the intelligence light adjustment layer are both white.
Implementation Method 2
The light-transmitting reflective layer is interposed between the display module and the intelligence light adjustment layer

AI summary
A display device includes a stacked structure and an outer frame fixedly receiving the stacked structure therein. The stacked structure includes an intelligence light adjustment layer, a display module, and a light-transmitting reflective layer interposed between the display module and the intelligence light adjustment layer. The intelligence light adjustment layer is configured to present one of a first state or a second state, which are different from each other, based on whether electrical power is applied to the intelligence light adjustment layer. The display module projects display images through the intelligence light adjustment layer in the first state. When the intelligence light adjustment layer is in the second state, the color of the outer frame is the same as the color of the intelligence light adjustment layer.
