Benefits of technology
This technology allows for creating a more durable and brighter type of electronic displays that can be used outdoors without losing their bright colors or causing damage over longer periods of use compared to traditional liquid crystal displays (LCDs). It also enhances the performance of certain types of electronics devices such as smartphones due to its ability to convert infrared radiation into visible lights instead of converting them directly onto LCD screens. Additionally, this technology helps reduce glare caused when displaying images on sunny surfaces while still maintain good image quality even after being exposed to rainwater during prolonged exposure. Overall, these technical improvements make electronic displays better than previous versions but they don't work well indoors because current methods have limitations like leaking moisture or absorbing too much heat.
Problems solved by technology
This patented technical problem addressed by this patents relates to improving micro-LED's performance when excited with green or red colors due to poor absorption efficiency caused from low angles at which they are emitted through openings on their surface. Additionally, there may also occur issues related to moisture ingress that can damage devices used within these systems.

The invention discloses a quantum dot flexible LED display device and a preparation method thereof. The quantum dot flexible LED display device comprises a flexible backboard, a flexible substrate anda packaging layer, the packaging layer is arranged between the flexible backboard and the flexible substrate, an LED chip array is arranged on the flexible backboard, the flexible substrate comprisesa second flexible substrate body, and separation walls are arranged on the second flexible substrate body; and the packaging layer covers and wraps the LED chip array and the separation walls, the separation walls are arranged in a surrounding mode to form a matrix cavity array, and the matrix cavity array is arranged above the LED chip array in a matched mode. The flexible backboard is in butt joint with the flexible substrate, the packaging layer is arranged between the flexible backboard and the flexible substrate, the water-oxygen barrier property of a light conversion layer is improved through the barrier effect of the packaging layer, and the service life of the display device is prolonged; and meanwhile, scattered light emitted by the LED chips is shielded by matching with the separation walls, so that the phenomenon that blue light emitted by the LED chips is diffused to adjacent pixel units is effectively limited, and the problems of blue light leakage and light crosstalk arereduced.
