Abstract

The present disclosure provides a substrate and an evaporation device used for manufacturing an organic light emitting display panel. The substrate includes a base plate; a plurality of layer formation areas on the base plate, wherein the layer formation areas are where an organic light emitting layer is formed; a plurality of first spacers disposed on the base plate at a clearance region between the layer formation areas; and a plurality of second spacers disposed on the base plate at outer peripheries of the layer formation areas, wherein each of the second spacers includes a photoresist material and a plurality of magnetic polymer microspheres.

Description

FIELD OF THE DISCLOSURE[0001]The present disclosure relates to the field of display panels, and more particularly to a substrate and an evaporation device used for manufacturing an organic light emitting display panel.BACKGROUND[0002]Organic light emitting diode (OLED) displays possess many outstanding properties, including self-illumination, short response time, large viewing angles, and high color saturation, and thus are used widely in a variety of applications. OLED displays include an organic light emitting layer on the substrate, where the organic light emitting layer is sandwiched between a cathode electrode and an anode electrode. A voltage is applied to the cathode electrode and the anode electrode to cause the organic light emitting layer to illuminate.[0003]To form the organic light emitting layer of OLED displays, an evaporation device is utilized to consecutively deposit a plurality of films on the substrate. OLED evaporation techniques heat an evaporation source that h...
