A preparation method of a novel wifi intelligent control curved surface LED display device

Abstract

The invention relates to the technical field of curved surface LEDs, and specifically relates to a preparation method of a novel WiFi intelligent control type curved surface LED display device. The preparation method comprises the following specific steps: S1, determining a project product to be of a separated module structure, and carrying out system structure design on an LED module; S2, carrying out circuit design on an infrared module, a WIFI module and an LED module; S3, after mold processing is completed, preparing a shell piece through an injection molding process; S4, carrying out SMTtechnology assembly on an LED lamp panel and a main control panel; and S5, researching and determining an assembly technology, and carrying out integral assembling on each component. A white LED lampbead is taken as a light source, multi-colored display is realized by printing different colors of printing inks on a diaphragm, and voltage difference among different colors of lamp beads is solved perfectly. A display module (integrated infrared module), a main control module and a WIFI module are separated, the interference among different signals during integration on the same PCB is reduced,and simultaneously, the exchange of each functional module is facilitated.

Description

technical field [0001] The invention relates to the technical field of curved LEDs, in particular to a method for preparing a novel WiFi smart-controlled curved LED display device. Background technique [0002] At present, the LED display modules used in conventional home appliances are composed of plastic casings, PCB boards, LED lamp beads, connecting wires, diaphragms, electronic components, etc., and can only simply indicate the status of home appliances when they are working. [0003] On the basis of the conventional LED display module, the client adds functions such as the main control module, infrared module and WIFI module. Related issues with this approach to development are: [0004] 1) The development progress is slow, the interference problem between modules cannot be solved in time, and there is a waste of PCB board resources; [0005] 2) The traditional colorful display adopts LED mounting display of different colors. There is a voltage difference of about 1V...

Problems solved by technology

[0004] 1) The development progress is slow, the interference problem between modules cannot be solved in time, and there is a waste of PCB board resources;

[0005] 2) The traditional colorful display adopts LED mounting display of different colors. There is a voltage difference of about 1V between different color LEDs, and the cost of the driving circuit rises significantly; poor consistency;

[0006] 3) The luminous effect design of the traditional curved surface structure uses a segmented PCB board to ensure that the distance between the LED lamp beads and the luminous surface is consistent to achieve a uniform luminous effect. This method is difficult to process, and there is a connection reliability problem between the PCB boards.
