Abstract
The field emission array (FEA), when used as a display device, requires a scanning driving circuit. Due to the large FEA capacitance (typically 5 pF for one pixel), the driving circuit is usually slow. In this work, a new driving circuit, which employs the voltage controlled current source (VCCS), overcomes the above-mentioned problem, thus can reach a high driving speed. In addition, the circuit has the advantages of a uniform current driving, the gray level control and the low power consumption.
