Thin Film Transistor-Addressed Display Device.
Abstract
Having achieved an operational 6x6 inch 20 1pi TFT-EL display the program has now been oriented to examine a major improvement in resolution (to 30 1pi) and in overall performance. This report describes initial design and fabrication of the 6x6 inch 30 1pi TFT-EL display. This will contain approximately 30,000 individually addressable elements with a 33 mils center-to-center spacing. In addition the design includes some significant design changes to increase the elemental 'lit' area. Further detailed characterization on the 6 x 6 inch 20 1pi display panel is also reported. Improved brightness and legibility in high brightness ambient has been achieved. Further power measurements confirm the initial data which indicated a low power dissipation level in the TFT-EL panel compared to other flat panel display technologies. The achievement of virtual operational perfection in the 6x6 inch 20 1pi (12,000 element) display is reported.
