Abstract
The invention provides an organic electroluminescent device, a luminescent module and application thereof. The organic electroluminescent device comprises a base plate as well as a working zone and a non-working zone which are positioned on the base plate, wherein the working zone comprises a display zone, a lead zone and an IC (Integrated Circuit) binding zone, and a nontransparent shielding layer is arranged on the non-working zone and not connected with the working zone. The non-working zone is provided with the shielding layer so that light rays emitted by a luminescent layer and refracted in an OLED (Organic Light Emitting Diode) screen body can not be transmitted out of the screen body and is shielded without influencing the normal use of the luminescent layer. Meanwhile, as the shielding layer and an auxiliary electrode are simultaneously prepared, a new process step is not increased so that the organic electroluminescent device is convenient for preparation. A mask plate designed for manufacturing the shielding layer is provided with a figure for preparing the shielding layer in the non-working zone.

Embodiment
The present invention is described in further detail below by specific embodiment.
Fig. 3 is the structural representation of organic electroluminescence device of the present invention, and substrate comprises upper surface and lower surface, and each on the viewing area layer and non-display area shielding layer all are arranged on the upper surface of substrate.Comprise viewing area A on the substrate, viewing area A comprises anode, organic layer, negative electrode, and first electrode is an anode, and second electrode is a negative electrode; The first contact conductor region D is connected with the anode of viewing area; Second contact conductor area B 1 and the B2 is connected with the even number line negative electrode with the odd-numbered line of viewing area A respectively; IC nation decides zone C, connects integrated circuit, drives organic electroluminescence device and shows.
Viewing area A, the first contact conductor region D, the second contact conductor area B 1 and B2, IC nation decide zone C and form the working region.The function that luminous demonstration, signal and power supply transmit is born in the working region.Also comprise the inoperative zone on the substrate, it is positioned at the gap of periphery, viewing area and working region, and the inoperative zone is used to protect the working region not to be subjected to extraneous infringement.
One deck shielding layer E is set on the inoperative zone, and shielding layer is made by semi-transparent or light-proof material, and shielding layer E shelters from the inoperative zone, therefore just can not penetrate from the inoperative zone by light 2.Working region and inoperative zone are not connected to each other, and the shielding layer E in inoperative zone can not be connected with lead-in wire yet, and working region and shielding layer E separate.
Fig. 4 is the view of observing along Fig. 3 direction of arrow, and shielding layer covers the part beyond the viewing area, stops light 2 to penetrate.
