Description

Technical Field

[0001] This utility model relates to the field of flexible display technology, and more specifically, to a curved LED flexible display with enhanced power replenishment function. Background Technology

[0002] With the continuous development and advancement of technology, flexible displays and LED soft screens are gradually entering people's daily lives. Combined with communication and interconnection with smart terminals such as mobile phones, they efficiently display and adjust the content displayed on the screen, bringing great enjoyment to practical use. However, existing LED soft screens still have many problems in terms of structural design and operational stability. In particular, for flexible display products with relatively large lengths, issues such as insufficient power supply and abnormal LED light emission are prone to occur in actual use, affecting normal operation.

[0003] A previously filed LED display screen, which effectively improves the stability of the screen display, includes a substrate layer, a conductive layer, a light-emitting layer, an AB glue encapsulation layer, and a main control circuit board located at one end of the substrate layer. The light-emitting layer is soldered to the printed circuit of the conductive layer, and the light-emitting layer is an LED light-emitting unit. It also includes positive and negative electrode copper strips for supplementing power. The positive and negative electrode copper strips are arranged in a single strip structure on the substrate layer, matching the length of the substrate layer, or the positive and negative electrode copper strips are arranged in several independent strip structures with uniform spacing, and are electrically connected to the main control circuit board through circuits. This technical solution can effectively solve the problem of insufficient power supply and abnormal LED light emission caused by the excessive length of the flexible display screen due to the inclusion of the supplementing copper strips. However, the supplementing copper strips are located on the outer edge of the front or back of the substrate layer, making the production process of the LED display screen more complex and costly. Therefore, a curved LED flexible display screen with enhanced power supplementation function is provided to solve the above problems. Utility Model Content
