A working stage system for flat panel displays and a flat panel display working method using the same. The working stage system for flat panel displays comprises a working table having a plurality of working positions sufficient to place at least two flat panel displays to be processed, a working unit disposed above the working table for continuously carrying out prescribed work on the flat panel displays loaded on the respective working positions, a unit-moving device for moving the working unit to or from the working positions, a loading/unloading unit for concurrently carrying out loading of the flat panel displays to be processed onto the vacant working positions and unloading the flat panel displays processed by means of the working unit from the working positions, and a controller for selectively controlling the loading/unloading unit, the working unit, and the unit-moving device. Loading and unloading of an LCD and the prescribed work on the LCD are concurrently carried out on the single working table to decrease loading and unloading time and increase the number of LCD's for which the working table carries out the prescribed work per unit time. Consequently, working efficiency is increased, and thus productivity is considerably improved.
摘要:
Provided are novel compounds in accordance with Formula I for an organic electronic material and an organic electroluminescent device using same.
