High Resolution Large Area 1000×700 Dot Thin-Film Electroluminescent Display Panel

Abstract

A large capacity, 704×1024 dot TFEL display panel with a density of 4.2 lines/mm was fabricated. In this paper, the limitations of large capacity TFEL panel scales and a design technique for TFEL film thickness parameters are described. In this panel for driving, 1024 columns of data are transmitted in parallel in four divided sections of 256 lines each, and 704 rows are interlace-scanned at a frame frequency of 70Hz. In addition, a stacked insulator structure is employed to overcome the breakdown tendency of TFEL panels. As a result, because a clear display of 50 cd/cm² luminance for each selected pixel was obtained without flicker, the feasibility of a large capacity TFEL display panel in established.
