I believe that both Sony and Sharp worked with Tektronix on the "PALC" panel, but as far as I know it, no consumer product was made.

Update (from NY Times):
"SONY AND SHARP FORM FLAT SCREEN VENTURE
Published: September 20, 1996
The Sony Corporation and the Sharp Corporation said yesterday that they would jointly develop a new type of flat panel display for use in computers and in television sets that can hang on a wall like a picture. The collaboration, to last three years, aims to produce a 40-inch screen using an approach developed by Tektronix Inc. of Wilsonville, Ore., that combines liquid crystal and plasma technologies. Sony and Sharp, which did not disclose any financial terms of the alliance, said they hoped to begin shipping samples by the fall of next year."
