Abstract

The invention relates to a light-emitting display body with uniform brightness and a preparation method thereof. The light-emitting display body with uniform brightness includes a conductive substrate, the conductive substrate is divided into a display area and a non-display area, and an OLED device is arranged on the display area. The non-display area is provided with an insulating film layer to prevent the short circuit of the OLED device, a recess is provided in the insulating film, and an auxiliary electrode lead electrically connected to the conductive substrate is provided in the recess. In the present invention, the insulating film layer (106) is provided with a recessed part, and auxiliary leads are arranged in the recessed part, so as to improve the luminous uniformity of the OLED lighting device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a luminescent display body with uniform brightness and a preparation method thereof, especially suitable for a large-sized display body. Background technique [0002] Organic electroluminescent display (English full name is Organic Light-Emitting Display, referred to as OLED) has the advantages of active light emission, light and thin, large viewing angle, fast response speed, energy saving, wide temperature tolerance range, flexible display and transparent display. Organic electroluminescent display OLED is a planar light source and does not require a light guide plate or a diffuser plate; the driving voltage is low and the heat dissipation is small; OLED is easier to realize transparent and flexible display, which can be applied to special occasions and open up new lighting markets, so It is regarded as the most potential new flat panel display technology of the next generatio...
