Problems solved by technology

However, in the production process, the larger the display size of the FOLED display, the more difficult the production process is, which is manifested in the high-generation mass production line that requires more capital investment and the lower large-area production yield, which greatly limits The rapid cost reduction of FOLED displays (especially large sizes) affects its market promotion

Embodiment Construction

[0027] The embodiment of the present invention provides a manufacturing method of a flexible organic electroluminescent diode display. In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The present invention proposes a method for manufacturing a flexible organic electroluminescent display (FOLED), and particularly relates to how to overlap flexible substrates, so as to realize the production of a large-size FOLED display from several small-size FOLED display units, that is, in the low-generation flexible The small-size FOLED display units of various shapes are first designed and fabricated on the substrate, and then the flexible substrates are overlapped by precise alignment to ensure the uniformity and consistency of the luminescent pixel arrangement required by the large-size display. The adv...

Abstract

The invention provides a fabrication method of a flexible organic electroluminescence diode display. The fabrication method comprises the following steps: providing a rigid substrate; attaching a flexible substrate onto the rigid substrate through an adhesive layer; fabricating an organic light-emitting display layer on the flexible substrate; packaging the organic light-emitting display layer to form a packaging layer; separating the rigid substrate from the flexible substrate; carrying out power on-test to a product obtained after the rigid substrate is stripped; cutting the product to form a FOLED (Flexible Organic Light-Emitting Diode) display unit; defining light-emitting zone on the FOLED display unit and non light-emitting zone located beyond the light-emitting zone; arranging the organic light-emitting display layer aligned with the light-emitting zone; supplying power to at least FOLED display units which are in display state; overlapping substrates of at least two FOLED display units through para-position, so that the non light-emitting zone of one FOLED display unit is overlapped with the light-emitting zone of the other FOLED display unit.

Description

Technical field [0001] The invention relates to a flexible display, and in particular to a method for manufacturing a flexible organic light-emitting diode (FOLED) display. Background technique [0002] At present, there are many types of display technologies for flexible displays, such as traditional liquid crystal display technology, bistable liquid crystal display technology, organic light-emitting diode (OLED) display technology, and electro-phoretic display technology. , Electrochromism (electrochromism, EC) display technology and electroluminescent (electroluminescent, EL) display technology, etc., among which the most attractive is the flexible organic light-emitting diode (flexible organic light-emitting diode, FOLED) display. The light-emitting principle of FOLED is similar to the light-emitting principle of ordinary OLED devices, that is, a very thin organic light-emitting material is deposited between two electrodes, and current is passed to the organic light-emitting...
