Abstract

The present invention discloses an organic light emitting diode display device and a manufacturing method thereof. The organic light emitting diode display device comprises a base plate comprising a substrate. A thin film transistor circuit layer is arranged on the substrate and has a control circuit; at least one groove is provided on the thin film transistor circuit layer; the bottom of the groove is provided with an electron transport layer; and at least one groove is filled with an auxiliary cathode layer. An anode layer is arranged on the thin film transistor circuit layer; a luminescentlayer is uniformly arranged on the anode layer; and the electron transport layer is also arranged on the luminescent layer. The cathode layer covers the electron transport layer and the auxiliary cathode layer, thereby the complexity of the thin film transistor circuit layer is avoided; the flatness of the pixel surface is ensured and the product yield is improved.

Description

technical field [0001] The invention relates to the field of display panels, in particular to an organic light emitting diode display device and a manufacturing method thereof. Background technique [0002] Organic Light-Emitting Diode (OLED) has become the most promising new display device in recent years due to its advantages of self-luminescence, all-solid-state, high contrast, etc. [0003] At present, the application direction of OLED includes RGB OLED technology composed of red (Red, R), green (Green, G), blue (Blue, B) and other three primary color pixels (pixels) arranged side by side (Side by Side), and white light OLED (WhiteOLED) plus color filter (Color Filter, CF) technology two categories. The products are mainly divided into small-sized mobile phones, tablet computer (Pad) screens and larger-sized TV (Television, TV) screens. [0004] In the direction of large-size OLED applications, the products currently on the market are concentrated in the bottom (Bottom...
