ABSTRACT:
An electro-optical display device having an improved connector arrangement. The display device includes a plurality of pixels arranged in commons and segments, with a lead trace associated with each commons and with each segment. These lead traces extend outward from an endmost commons to an edge of the device for subsequent connection to driving apparatus. The set of leads associated with the set of commons extends normally from such set of commons to the proximate edge of the device. The remaining set of leads, associated with the segments, is provided with lead traces which are redirected to also extend towards this same side of the device. As such, all leads for the device are accessible on a single side of the device. This may be accomplished by dividing the remaining set of commons in half, with each of these half-sets of leads being directed to a location on an associated side of the initial leads for the first set of commons. In this manner, a single connection is required between the device and the driving equipment, with such a connection typically being capable of formation by a low cost heat seal.
