The TV application includes the three functional sections  of 'power supply', 'main board' and 'screen driver'

¡ñ Power supply: driven by high voltage DMOS transistor, driven by linear regulator circuit, DC-DC circuit, driven by reference power supply circuit

¡ñ Screen driver: driven by medium and low voltage DMOS transistor

¡ñ Main board: driven by low voltage low current DMOS transistor
