ariable DC voltage. Diagram 3-9 is a drive circuit. The display mode of volume and sales on main display board adopt 6 digits liquid crystal display (Model ED-139, see Diagram 3-11), PPU or unit price r digits LCD (Model ED-830, see Diagram 3-12). Diagram 3-9: Static circuit and wave of LCD tube Diagram 3-10: Drive circuit of one-digit tube Diagram 3-11: ED-139 6-digit LCD Diagram 3-12: ED-830 4-digit LCD Display drive chip often adopts 8-digit memory/flip-latch: 74HC95. The drive circuit of liquid crystal display is composed of double D trigger 74HC74 and double input exclusive-OR gate 74HC86 fuel dispenser . Some fuel dispensers adopt special cry fuel dispenser stal drive circuit in liquid crystal display, its principle basically similar to 74 series LCD drive circuit. A few fuel dispenser manufacturers adopt light-emitting diode (LED) as display components of display board because its cost is low and need not backlight in evening. The defect of this display component is bad display effect, especially under extensive sunlight, and much electricity consumption. LED display drive circuit also has parallel and serial drive, similar to LCD display drive circuit in terms of structure. Very few fuel dispensers adopt matrix or color liquid crystal display, showing much information. However, it largely increases cost. 2.4 Power supply Stable voltage power supply used in explosion-proof fuel dispenser Most o fuel dispenser f fuel dispensers adopt explosion-proof type, installing liner stable voltage power supply or switch voltage power supply. Switch voltage stabilizing power supply includes power transformer, DC/DC converter, 220V direct commute and pulse transformer, illustrated in Diagram 3-14 and 3-15. Due to cost-efficient and simple design, liner stable voltage power is widely adopted. However, it is affected by exterior network voltage. Although pulse transformer is able to tackle with network voltage fluctuation, it is can’t afford because of complicated technology, expensive cost and difficult to maintenance. In recent years, D
