Edge-to-Edge Mobile Terminal Display with Curved AMOLED
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional smartphones have a narrow edge effect due to reserved areas for handsets and physical buttons, limiting the expansion of the display area, and OLED displays suffer from non-displayable black edges when viewed from the side, affecting the display quality.
Innovation Solution
A smartphone design featuring a groove structure with a circuit board and flexible AMOLED display module, where the screen module extends along the sides of the back shell, and a transparent cover plate seals the groove, creating a seamless display area without borders, using an arching design to eliminate black edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display area is expanded in the X direction to achieve narrow edges on two sides, then the appearance becomes more beautiful, but the top and bottom areas still need to reserve space for handset and physical buttons, so the display area cannot be expanded in the Y direction
Solution Approach 1:
The patent moves the handset and physical buttons from the front surface to the side surface of the device. This spatial reconfiguration allows the display area to expand to the edges of the front surface without compromising operational functionality, as users can access buttons and handset on the side rather than reserving front surface space
Solution Approach 2:
The device is segmented into distinct functional zones: the front surface is dedicated entirely to display, while the side surface houses operational elements like buttons and handset. This segmentation allows each surface to optimize its primary function without interfering with the other
2Illumination intensity
If flexible curved screen technology is used to improve the black edge of the front screen, then the front display effect is improved, but when viewed from the side, black edges are still obvious, resulting in defects in display effect
Solution Approach 1:
The patent employs a curved screen design that extends from the front surface along the side surface of the device. This continuous curvature eliminates the abrupt edge transitions that cause black edges, allowing the display to smoothly wrap around and maintain visual continuity when viewed from the side
Solution Approach 2:
The display transitions from a two-dimensional flat surface to a three-dimensional curved surface that wraps around the device. This dimensional transformation allows the screen to eliminate side-view black edges by extending the display area onto the side surface, creating a seamless visual experience from multiple viewing angles

AI summary
The present invention discloses a mobile terminal, comprising a bottom frame; a glass cover; a screen module covering the bottom frame; wherein the glass cover covers the screen module and two edges of both sides of the glass cover connect to the bottom frame; both the screen module and the glass cover have an arch opposite to the bottom frame; two edges of both sides of the screen module extend over both sides of the glass cover and are covered by the bottom frame. The beneficial effect of the above technical solution is: by utilizing the arch of the screen module and the glass cover opposite to the bottom frame, the front surface of the screen module and two sides of screen module do not have black edge, so that the display effect is excellent.
