Abstract

The invention discloses a light emitting diode display panel and a manufacturing method thereof, and a display device, and relates to the technical field of display. The light emitting diode display panel includes a thin film transistor backboard and a light emitting structure, the light emitting diode display panel also includes a protective film, and the protective film is located between the thin film transistor backboard and the light emitting structure and covers grid lines and data line in a display area of the light emitting diode display panel. The protective film also covers a circuit in the periphery of the display area of the light emitting diode display panel. According to the light emitting diode display panel in the invention, a protective film process is added to a manufacturing process of an existing light emitting diode display panel, thereby effectively preventing a scratch of the thin film transistor backboard by an evaporation mask plate in manufacture of the light emitting structure and preventing a static electricity problem caused thereby.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a light-emitting diode display panel, a manufacturing method thereof, and a display device including the light-emitting diode display panel. Background technique [0002] Compared with the liquid crystal display that currently dominates the market, the light-emitting diode display has the advantages of simple process, wide viewing angle, fast response speed, high brightness, high contrast, bright color, wide working range, light weight, thin thickness, and low power consumption. Series advantages. [0003] In the production process of the light-emitting diode display panel, when the light-emitting layer is evaporated by mask evaporation method, the mask plate and the thin film transistor backplane need to be closely attached. If the edge of the mask plate is defective, it will When it is in place, it will scratch the backplane of the thin film transistor, resulting in s...
