The new electroluminescent (EL) display drivers introduced by Texas Instruments were developed using the patented B I DFET process which incorporates bipolar, double-diffused, N-channel and P-channel MOS transitors on the same monolithic substrate. The integrated circuit designs were facilitated by experience gained designing reliable high voltage ac plasma drivers. Functionality of these devices IA as based on what currently appears to be the most feasible approach to driving EL panels. This paper will discuss the important device characteristics and system considerations required to use these drivers.
