Methods of Forming Bent Display Panels - A simplified explanation of the abstract
This abstract first appeared for US patent application 18176931 titled 'Methods of Forming Bent Display Panels
Simplified Explanation
- The patent application describes a method for increasing the curvature of a display panel and allowing for compound curvature. - The display panel is initially formed in a flat state and then bent to achieve the desired curvature. - Additional display components that may be damaged during the bending process are added after the panel is bent. - A flexible printed circuit is formed directly on the display panel using precise deposition of conductive material. - This allows for electrical connections to be made in regions of high curvature without causing any visual artifacts on the display.
Original Abstract Submitted
A display may have one or more bent portions. To increase the magnitude of curvature in a display and/or to allow for compound curvature in the display, a display panel may be partially formed in a planar state. The partial display panel is then bent to have desired curvature. After the partial display panel is bent, additional display components that are susceptible to damage during the bending process may be added to complete the display panel. A flexible printed circuit may be formed directly on the display panel using precise deposition of conductive material. By forming the flexible printed circuit layer-by-layer directly on the display panel, no substantive pressure needs to be applied to the display panel. Electrical connections may therefore be made to the display panel in regions of the display with high levels of curvature and/or with compound curvature without causing front-of-screen artifacts for the display panel.
