The backlight power difference in the market is about 400W, and the total power of the power supply board is about 510W together with electric equipment such as a T-CON, a main board and a power amplifier, so that the power supply board with the power supply board of 600W can meet the requirements only by designing the power supply board with the power supply board. The television is designed to be thinner, the thickness of the whole machine with a large size is about 40mm, so that the maximum thickness of a designed power panel is less than or equal to 17mm in consideration of the requirements of safety distance and the like in safety regulations, and the thinner the power panel is, the less the power can be increased, otherwise, the larger the power panel is, and the production is not facilitated. Therefore, if the power panel outputting 600W is made and the production is facilitated, the design is completed by matching two power panels, the power of 300W is output by each power panel on average, and one power panel is closed by a relay in standby, so that the standby power can be ensured to be lower than 0.5W. Thereby the power panel satisfies the design requirement: high power, thin thickness, low standby power consumption, etc.
