Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0031] Such as figure 2 As shown, it is a schematic structural diagram of a pixel unit in an embodiment of the present invention, figure 2 A substrate 21 and a pixel unit located on the substrate 21 are shown, the pixel unit includes a pixel defining layer 25, a first electrode 22, an organic layer 23, and a second electrode 24, and the pixel defining layer 25 defines a pixel region, The organic layer 23 is formed in the pixel region and is located on the first electrode 22, and the second electrode 24 is formed on the organic layer 23; wherein, the pixel defining layer 25 is provided with at least A groove 26. It can be seen that the pixel unit provided by the present invention cuts off the organic layer of the adjac...

Abstract

The invention discloses a pixel unit and a manufacturing method therefor and a display apparatus. The pixel unit comprises a pixel defining layer, a first electrode, an organic layer and a second electrode, wherein a pixel region is limited by the pixel defining layer; the organic layer is formed in the pixel region, and positioned on the first electrode; and the second electrode is formed on the organic layer, wherein at least one groove is formed in the pixel defining layer. By forming the groove in the pixel defining layer, the organic layer of the adjacent pixel units can be blocked; when the organic layer is evaporated, the organic layer is blocked in the groove without being covered with a step easily, namely, without causing a climbing effect easily; and therefore, movement of current carriers on the first electrode to a non-pixel region can be avoided, thereby avoiding recombination of positive charges and electrons in the non-pixel region.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel unit, a manufacturing method thereof, and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) is expected to replace TFT-LCD (Thin Film Transistor-Liquid) due to its many advantages such as self-illumination, thinness, good color gamut, low power consumption and flexibility. Crystal Display, TFT-LCD) a new generation of display technology. [0003] At present, OLED technology has gradually matured and slowly entered the market, especially small-sized OLED panels. However, due to the large size of the large-size OLED panel, the shadow effect (Shadow Effect) produced by the high-precision metal mask (Fine Metal Mask, FMM) process is relatively serious, and the white organic light emitting diode (White Organic Light Emitting Diode, WOLED) + color filter (Color Filter, CF) technology, WOLED technology is mostly a two-layer structure ...
