Problems solved by technology

A metal material is used to connect the light-emitting diodes and the soft board, and the flexible LED light source soft board is used as a large display panel. However, due to the shortcoming of the metal material being opaque, the lighting effect is greatly reduced.
And China Taiwan Invention Patent No. 369731 "Light-emitting diode with transparent glass or quartz as permanent substrate and its manufacturing method" discloses: the method of making light-emitting diode with transparent glass or quartz as permanent substrate, but its manufacturing process is complicated and complicated It is costly, and it is impossible to directly adhere the light-emitting diode device to the glass substrate. Its practical application is not easy to construct, and the production method is costly

Embodiment Construction

[0039] see figure 1 , is a three-dimensional appearance view of the display screen of the first embodiment of the present invention. The present invention is composed of a flexible substrate 10, a plurality of conductive circuits 20 and a plurality of light-emitting diode devices 30, wherein the flexible substrate 10 can be poly Diethyl terephthalate (PET, Polyethylene terephthalate), polypropylene (PP, polypropylene), polyimide (PI, Polyimide) or acrylic (PMMA, Polymethylmethacrylate) and other light-transmitting or opaque materials The composition of the substrate is larger than 10cm×10cm. The substrate can also be a flexible printed circuit board (FPC, Flex Printed Circuit). The base material of the flexible board can be PP or PET. Printed circuit boards (PCBs) can be produced by etching, which can produce single-sided, double-sided or multi-layer flexible boards, and can be embedded in parts for processing, such as the light-emitting diode device of the present invention, ...

Abstract

The invention relates to a flexible light emitting diode (LED) display screen which is realized by a method that a plurality of LED devices and conducting wires are arranged on a flexible substrate, and the LED devices and the conducting wires are electrically connected, thus, the utilization area of the flexible LED display screen can be adjusted as required, and the flexible LED display screen can be applied to application surfaces of planes or curved surfaces of different specifications as a display screen for a display board. Through the material characteristic of flexible plasticity of the flexible substrate, the flexible LED display screen can be flexibly jointed on the application surface effectively so as to improve the convenience of use and construction of the flexible LED display screen in a back gum pasting mode.

Description

technical field [0001] The invention relates to a display device, in particular to a flexible light emitting diode (Light Emitting Diode, LED) display screen. Background technique [0002] In today's advanced technology and increasingly rapid information dissemination, in order to achieve advertising benefits such as introducing products to consumers or conducting publicity immediately, anytime and anywhere, most of them directly use advertising billboards, posters, signs or display screens to achieve their publicity. effect, and it is also a new type of advertising trend to set or post advertising billboards or display screens directly in the passenger compartment or outside the vehicle body of public transport and other means of transportation; however, these used advertising billboards The assembly and installation of posters, signboards or display screens are relatively complicated, and they cannot be bent arbitrarily and placed on any curved surface area, so it is impos...
