Abstract
The use of ferroelectric transchargers as storage and control elements in an electroluminescent matrix display is reported. Research on display panel circuitry led to control circuits useful for solid-state matrix display. In these circuits, ferroelectric elements provide analog storage and control energization of electroluminescent cells in accordance with stored analog signals. The ferroelectric, in conjunction with a diode, provides a selection threshold which permits the element to be addressed in a matrix by voltage coincidence. The new circuits give greatly improved brightness and contrast compared with previous ferroelectric control circuits. Transcharger circuits with logic capability have also been developed; such circuits are especially useful for bar graph, moving pointer, and similar displays. Three experimental model displays demonstrated brightness as high as 48 ft-L; contrast ratio in excess of 100:1; geometric resolution as great as 10-elements per in.; capability for producing a gray scale; and a frame rate which allows continuity of motion without blurring or flicker. The performance of these models demonstrates the potential of using ferroelectric control circuits and electroluminescent elements for high-brightness, high-resolution, all solid-state matrix displays.
