Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0024] In the prior art, the manufacturing device of the display panel generally includes an evaporation chamber and a substrate fixing device, and the substrate is evaporated in the evaporation chamber, so that the molecular arrangement in the light-emitting layer of the display unit in the display panel produced in this way is dense. Poor stability and stability, the excitons generated in the light-emitting layer are easy to interact with the film layer of the adjacent light-emitting unit, resulting in faster deg...

Abstract

The invention discloses a display panel manufacturing device and method. The display panel manufacturing device comprises a vapor plating cavity, a substrate fixing device, a heating device and a temperature controller; the substrate fixing device is arranged on the wall of the vapor plating cavity and used to fix a substrate; the heating device is arranged on the substrate fixing device and usedto heat the substrate; and the temperature controller is electrically connected with the heating device, and used to control the heat device to heat the substrate vapor-plated with a first light emitting layer to a first preset temperature, and cools the substrate to a second preset temperature after a first preset period. The problem that a display panel manufactured by a present display panel manufacturing device is short in life is solved, the first light emitting layer is more stable, the service life of the display panel is prolonged, and power consumption of the display panel is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular, to a manufacturing device and method of a display panel. Background technique [0002] Organic Light-Emitting Diode (OLED) display panel occupies a place in the display field due to its advantages of thinness, flexibility, high contrast ratio and wide color gamut. [0003] The colorized display of existing OLED display panels mostly adopts RGB pixel independent light-emitting technology, that is, a pixel is formed by preparing red (R), green (G), and blue (B) three primary color light-emitting units, and the color mixing of the three color combinations is adjusted. Than produce true color. However, the display panels manufactured by the existing display panel manufacturing devices have the problem of short service life. Contents of the invention [0004] The invention provides a manufacturing device and a manufacturing method of a display panel to...
