OLED display panel and manufacturing method thereof

Abstract

The present application discloses an OLED display panel and a manufacturing method thereof. The panel includes: a first substrate, and a plurality of sub-pixels located on the surface of the first substrate; the sub-pixels include a plurality of sub-pixels located on the surface of the first substrate Thin film transistor; a first electrode layer located on the surface of the thin film transistor away from the first substrate; a reverse electric field layer located between the thin film transistor and the first electrode layer; located on the first electrode layer away from the a luminescent material layer on the surface of the first substrate; a second electrode layer located on the luminescent material layer away from the surface of the first substrate. In the OLED display panel of the present invention, when the thin film transistor is turned off, the reverse electric field generated by the reverse electric field layer corresponding to the corresponding sub-pixel will interact with the residual forward electric field in the sub-pixel, thereby weakening or even canceling the sub-pixel The residual forward electric field in the pixel solves the problem of stealing brightness of sub-pixels in the prior art to a certain extent.

Description

technical field [0001] The present application relates to the field of display technology, and more specifically, relates to an OLED display panel and a manufacturing method thereof. Background technique [0002] With the continuous development of display technology, the application of display panels is becoming more and more extensive. OLED (Organic Light Emitting Diode, organic light-emitting diode) display panels have become a rising star in the display panel industry due to their advantages such as fast response speed, brilliant colors, thinness and convenience. [0003] The structure of the organic light-emitting display panel in the prior art is generally: a substrate, a plurality of thin film transistors arranged on the substrate, an anode layer, a hole injection layer, a hole injection layer, A hole transport layer, a light emitting material layer, an electron transport layer, an electron injection layer, and a cathode layer. Wherein, the patterned structure of the ...
