The role of the power board
1. Basic knowledge of power supply The role of the LCD power supply is to provide energy for the whole machine. The appearance of the common power adapter is shown in the figure. Its input is 220V AC and the output is 12V, 4A DC.
2. Common forms of LCD power supply Common LCD power supplies are built-in and external. The built-in power supply is usually made together with the high-voltage board to form a two-in-one power board. The power board generates all the voltages required by the driver board. The external power supply is also commonly referred to as a power adapter. It generally has a 220V AC input and a 12V DC output. Other power sources required by the driver board are converted on the driver board.

The circuit board is mainly composed of pads, vias, mounting holes, wires, components, connectors, filling, electrical boundaries, etc. The main functions of each component are as follows:
Pads: metal holes for welding component pins.
Vias: There are metal vias and non-metal vias, among which metal vias are used to connect component pins between layers.
Mounting holes: used to fix the circuit board.
Wires: electrical network copper films used to connect component pins.
Connectors: components used to connect between circuit boards.
Filling: copper plating for ground network, which can effectively reduce impedance.
Electrical boundary: used to determine the size of the circuit board. All components on the circuit board cannot exceed this boundary.

Working principle of power board
Since LCD uses low voltage to work, and the general mains power provides 110V or 220V AC voltage, the display needs to be equipped with a power supply. The function of the power supply is to convert the 220V AC voltage of the mains into 12V or other low-voltage DC to power the LCD display. The power supply part of the LCD display uses a switching power supply. Because the switching power supply has the advantages of small size, light weight, and high conversion efficiency, it is widely used in various electronic products, especially pulse width modulation (PWM) type switching power supplies. The characteristics of the PWM type switching power supply are fixed switching frequency and voltage adjustment by changing the duty cycle of the pulse width.
The basic working principle of PWM switching power supply is: the 220V AC input power supply is rectified and filtered to become a 300V DC voltage, which is then controlled by the switching power tube and stepped down by the high-frequency transformer to obtain a high-frequency rectangular wave voltage, which is rectified and filtered to obtain various DC output voltages required by the display. The pulse width modulator is the core of this type of switching power supply. It can generate a driving signal with a fixed frequency and adjustable pulse width, control the duty cycle of the switch power tube, and adjust the output voltage to achieve the purpose of voltage stabilization.
