In recent years, many portable consumer electronic products have been sold on the market, such as 3G-4G iPhone mobile. Electroluminescent Lamps (EL) technology is widely used as the display application of liquid crystal and backlighting because of the physical thinness and light uniformity, generating low power consumption for illumination lamp load with capacitance structure, especially lower cost than that of LED products recently. A low cost silicon BCD technology in place of high cost SOI BCD technology for monolithic integrated EL driver ICs application is put forward. Several key technologies are presented. An advanced SEJTET termination technology was designed instead of the conventional PIOS isolation to obtain smaller chip area and protect HVICs from the occurrence of di/dt effect under PWM operation.
