Description
Technical Field
The invention relates to the technical field of advertising media, in particular to an outdoor advertisement display structure based on a flexible OLED technology.
Background
The outdoor screen advertisement technology in the current market is as follows: traditional LED display screen, LED photoelectric glass, OLED outdoor display screen.
The traditional outdoor LED display screen mainly comprises an outdoor large screen, although the LED display screen has already entered a small-distance era, and indoor application also enters the wide application of the commercial display field, the outdoor P10 dot-space product has a large part of market share according to the old due to factors such as application scenes, viewing distance and the like. In general, products with a pitch of P5-P10 points still have their way. Although outdoor products such as P3 and P4 have been developed for a long time to expand the application range of outdoor LED displays and move to smaller dot pitches as indoor products, even small-pitch products such as outdoor P2.0 are proposed, outdoor small-pitch products have an embarrassing situation when they are dropped on the ground compared to indoor small-pitch products. The main technical problems are as follows: the LED display screen is relatively thick and heavy and is limited by outdoor installation positions.
The LED photoelectric glass is attached to the substrate glass, belongs to a single-sided display screen, and has a permeability of 80-98%. The product can be applied to places with glass curtain walls. Such as banks, malls, theaters, commercial streets, chain stores, hotels, municipal public buildings, landmark buildings, and the like. The main technical problems are as follows: the LED photoelectric glass has insufficient display precision and has certain limitation in some small-area application scenes.
The existing OLED technology has difficulty in manufacturing an outdoor display screen, OLED light-emitting parts are easy to oxidize when contacting air and are sensitive to water vapor, and molecular chains of organic matters in the OLED are broken by short-wavelength ultraviolet rays under the irradiation of ultraviolet bands, so that organic materials are damaged, and the service life of the OLED is greatly shortened.
Chinese patent No. 201620171402.2 discloses an OLED display screen billboard with a hoop cylindrical rod, in which the OLED display screen is arranged in the cylindrical rod. Chinese patent No. 202010509000.X discloses an outdoor advertising is with preventing OLED screen of touching protection, including base, fixed plate and the OELD screen of inlaying in the fixed plate of establishing, the OLED screen overcoat has connect the protection screen, the solar cell electricity is connected with the touch protection structure of preventing that sets up in the protection screen, the stock solution chamber has been seted up in the fixed plate, the intercommunication has the inlet tube in the stock solution chamber, it includes a plurality of crossbands and vertical retort to prevent touching the protection structure, and is a plurality of the crossbands are connected with first collecting ring jointly, and are a plurality of the vertical retort is connected with the second collecting ring jointly. Above-mentioned patent is through installing OLED display screen in cylinder pole or protection device, solves OLED display screen and is afraid of the ultraviolet ray, afraid of the problem of vapor, but cylinder pole or protection device have the limitation in outdoor advertising promotes, can't use on a large scale.
The flexible OLED can be bent and folded, and is more and more attracted by market attention, the structure of the flexible OLED device mainly comprises a Back Plate (BP) and an organic light Emitting Layer (EL), the back plate part is adopted, the conventional flexible AMOLED device usually adopts an LTPS (low temperature polysilicon) back plate, in order to prevent water, oxygen and dust from entering the OLED display device to cause the reduction of the service life and the performance of the OLED display device, the development of an OLED packaging process is necessary, and the conventional packaging technology is glass or metal cover plate packaging and film packaging, and cover plate packaging: under the environment of filling inert gas, the OLED glass is bonded with the glass cover plate or the metal cover plate by using ultraviolet light curing glue, so that an organic layer and an electrode which are clamped between the cover plate and the substrate are sealed, and the external water oxygen and dust are isolated. The disadvantage of cover plate encapsulation is that metal cover plates are easy to warp and deform, while glass cover plates are fragile and not suitable for developing flexible OLED technology, thin film encapsulation: the method is a mainstream OLED packaging process at present by depositing a thin film protective layer with a certain thickness to replace cover plate packaging. For outdoor irregular building glass, flexible OLED is the best choice, but the flexible OLED technology cannot cope with outdoor environment at present.
