Engineers Try to Solve Ultrathin TVs
Ro Jae-song, a materials science professor here, has spent the past eight years researching a display technology called OLED, which is now used for some high-end cellphone screens.
Mr. Ro does contract research for South Korea’s two big electronics makers, Samsung Electronics Co. and LG Electronics Co., on a difficult problem: How to build OLED screens big enough for large televisions.
It’s one of the hot topics among display researchers and manufacturers who are meeting in Los Angeles for the annual conference of the Society for Information Display, or SID. More academic gabfest than trade show, engineers will trot out their latest ideas for displays as small as sheet-like films that roll up in a pen to as large as roadside billboards.
