Problems solved by technology

In the OLED production process, the shrinkage of the flexible substrate after solidification and film formation on the glass substrate will aggravate the deformation of the glass substrate. The deformation of the glass substrate gradually increases from its edge to the center position. When it is attached under the action of a magnet, the Mask and the glass substrate will not be tightly attached, resulting in shadow effects and color mixing

Abstract

The invention discloses a bearing substrate for bearing an OLED (Organic Light Emitting Diode) during preparation of the OLED. The bearing substrate comprises a substrate part and an adsorbed layer arranged on the surface of the substrate part, wherein the adsorbed layer comprises a resin layer and a plurality of magnetic nano particles distributed in the resin layer. The invention further discloses a preparation method of the bearing substrate. During the preparation of the OLED, the gravity of the substrate can be counteracted or reduced by an attractive force of an adsorbent to the adsorbed layer, so that deformation caused by gravity sag of the substrate for bearing the OLED during the preparation of the OLED can be eliminated or reduced; and a shadow effect and evaporation color mixture in a preparation process can be further avoided.

Description

technical field [0001] The invention belongs to the field of organic light-emitting technology, and in particular relates to a carrying substrate used for carrying OLEDs when manufacturing OLEDs and a manufacturing method thereof. Background technique [0002] In recent years, Organic Light Emitting Diode (OLED) has become an emerging flat-panel display product at home and abroad, because OLED displays have self-illumination, wide viewing angle (over 175°), short response time (1μs), high luminescence Efficiency, wide color gamut, low operating voltage (3-10V), thin panel (thickness can be less than 1mm), large-size and flexible panels can be produced, and simple manufacturing process, and it also has the potential of low cost. [0003] In the production process of OLED, the glass substrate sags under the influence of gravity in the evaporation machine, thereby causing deformation, and as the size of the glass substrate becomes larger and thinner, the amount of deformation i...
