I. Production method of LED display screen based on PCB board
LED display screens are now widely used in indoor, outdoor and architectural fields, and have become an important information dissemination medium. LED display screens based on PCB boards are one of the common production methods. The following introduces its production method.
Material preparation:
PCB board, LED lamp beads, resistors, capacitors, driver chips, connecting wires, power supply
Steps:
1. Make circuit boards: Draw circuit patterns on PCB boards according to design drawings, and solder components such as resistors and capacitors on the circuit boards.
2. Install LED lamp beads: Reserve LED lamp bead jacks (usually positive and negative holes) on the circuit board, and solder LED lamp beads with a soldering iron.
3. Connect the driver chip: Connect the driver chip of the LED screen to the circuit board, and pay attention to the correct connection of the line.
4. Install the power supply: Connect the power supply to the interface of the adapter on the circuit board, turn on the power, and test the LED display screen.
5. Install the shell: Use appropriate materials to make the LED display shell, and install the PCB board and driver board into the shell to improve the appearance of the display.
To make an LED display screen based on PCB board, you need to have basic knowledge of electronic circuits and welding skills. At the same time, you need to pay attention to the selection and connection method of driver chips and LED lamp beads, otherwise it may affect the brightness and stability of the screen.
II. Production method of LED display screen based on lamp bead assembly
In addition to the production method based on PCB board, LED display screen can also be made by lamp bead assembly. The production method is introduced below.
Material preparation:
LED lamp beads, power supply, circuit board, pliers, connecting wire
Steps:
1. Prepare power supply: Select a suitable power supply and pay attention to the matching of voltage and current.
2. Make circuit board: According to needs, make circuit boards of corresponding length and shape, and cut the board with pliers to make it meet the required size.
3. Install LED lamp beads: Paste the LED lamp beads on the circuit board and connect the lamp beads with pliers.
4. Connect power supply: Use connecting wire to connect the power supply to the LED lamp beads.
5. Test and debug: Turn on the power supply, test and debug the brightness, color, and on and off status of the lamp beads to ensure that the lamp beads are well assembled.
6. Install the shell: Select the appropriate shell material according to the needs, fix the LED lamp beads in the appropriate position, and store or fix the circuit board and connecting wires.
The production method of LED display screen based on lamp bead assembly is relatively simple and suitable for some small and simple application scenarios. It should be noted that the number and position of the lamp beads, the size and output power of the power supply should be adjusted according to the needs during production, and the size and shape of the circuit board should be matched.
