Abstract

The invention discloses a display panel and a preparation method, a display screen and a display terminal. The display panel comprises a plurality of first electrodes arranged at intervals along a first direction, a first conductive material layer arranged between the first electrodes, an insulating layer filling the areas between the first electrodes and the first conductive material layer and exposing the first conductive material layer, an organic functional layer arranged on the first electrodes and the insulating layer and exposing the first conductive material layer, and a plurality of second electrodes arranged at intervals along a second direction, arranged on the organic functional layer and electrically connected with the first conductive material layer. According to the invention, the first conductive material layer is used as the leads of the second electrodes to lead the second electrodes out of the display panel. Compared with the arrangement mode of setting the electrodeleads on both sides of the screen body in the prior art, the electrode leads of the second electrodes of the display panel are arranged between the first electrodes, which can reduce the width of thescreen body, improve the utilization rate of the substrate and reduce the cost.

Description

Technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a preparation method, a display screen and a display terminal. Background technique [0002] OLED (Organic Light Emitting Diode, organic light-emitting diode) is also known as organic electroluminescence, organic electro-laser display or organic light-emitting semiconductor. OLED display technology has the advantages of self-luminescence, wide viewing angle, high contrast, low energy consumption and thinness. , More and more widespread attention. [0003] According to different driving methods, OLEDs can be divided into PMOLED (Passive Matrix OLED, passively driven organic light-emitting diodes) and AMOLED (Active Matrix OLED, actively driven organic light-emitting diodes). Among them, the electrodes of the same nature of the display cells of the same row of the PMOLED display array are shared, and the electrodes of the same nature of the display cells of the same ...
