Mobile Display Electroluminescent Border to Reduce Black Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current displays are hindered by black frames in the non-display regions due to wires covered with black ink, which affect the visual experience and do not align with the trend of higher visual quality sought by users.
Innovation Solution
An electroluminescent film layer in the non-display region is illuminated, and a white ink layer covers the electroluminescent film to concentrate light, reducing or eliminating the black frame without decreasing the screen-to-body ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If wires in the non-display region are covered with black ink to hide them, then the wires are concealed, but a black frame is formed that affects appearance and reduces visual experience
Solution Approach 1:
The patent converts the harmful black frame effect into a beneficial feature by using the same non-display region to house an electroluminescent film that emits light. The wires are still present but are optically concealed by the emitted light, transforming the dark aesthetic problem into a light-emitting solution that eliminates the black frame appearance while maintaining wire functionality.
Solution Approach 2:
The patent changes the optical property of the non-display region from absorbing light (black ink) to emitting light (electroluminescent film). This color/optical property transformation converts the black frame problem into a bright, light-emitting border that improves visual experience while still concealing the underlying wire structure.
2Illumination intensity
If the non-display region is illuminated to eliminate the black frame, then visual experience is improved, but the screen-to-body ratio may be reduced
Solution Approach 1:
The patent applies local quality by illuminating only the peripheral non-display region with the electroluminescent film while keeping the central display region unchanged. This localized illumination approach eliminates the black frame effect at the borders without encroaching on the display area, thus maintaining the screen-to-body ratio while improving overall visual experience.
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
The solution enhances user experience by minimizing the black frame while maintaining the display's overall appearance and functionality.
Implementation Method 1
an electroluminescent film layer disposed in a non-display region of the display illuminates the non-display region
Implementation Method 2
a white ink layer disposed on the electroluminescent film layer in the non-display region covers a color of the electroluminescent film layer and concentrates light to the non-display region

AI summary
The invention discloses a display screen. The display screen comprises a display area and a non-display area surrounding the display area. The display screen further comprises a main board, wherein the non-display area is covered with an electroluminescent film layer, and the electroluminescent film layer is electrically connected to the main board. By arranging the electroluminescent film layer on the non-display area of the display screen to illuminate the periphery of the display area, a black frame of the display screen is reduced and even taken away, so that the screen-to-body ratio of a mobile electronic equipment is increased, and user experiment is improved.
