Embodiment 1

[0039] This embodiment provides a pixel structure, including a plurality of pixel units arranged in a matrix, and each pixel unit includes:

[0040] the first sub-pixel 100; and

[0041] At least two second sub-pixels 200 are juxtaposed and adjacent, and the organic materials of the at least two second sub-pixels 200 are connected to each other.

[0042]The second sub-pixel in the pixel unit corresponds to the electrode formed by etching the integrally formed organic material, that is, the step of forming the second sub-pixel includes two steps: the first step, etching to form one of the electrodes, and the second step, OLED organic materials are evaporated by FMM, and in the third step, the common electrodes of all OLEDs are evaporated. After the first step, the second sub-pixel is etched to form at least two independent electrodes, and then a red or blue organic material layer is formed on the substrate by evaporation using a mask plate. Although the organic material is integr

Embodiment approach 1

[0047] Embodiment 1: The color of the second sub-pixel in the sub-pixel unit is different from the color of the second sub-pixel in the adjacent sub-pixel units in the row direction, that is, the pixel units 10A are aligned in a row, as shown in the schematic diagram Figure 5 As shown, the pixel units in the row direction are distributed as red-green combination, blue-green combination, red-green combination, and blue-green combination, and the pixel units in the column direction are distributed as a red-green combination and a blue-green combination;

Embodiment approach 2

[0048] Embodiment 2: The color of the second sub-pixel in the sub-pixel unit is different from the color of the second sub-pixel in the adjacent sub-pixel units in the column direction, that is, the pixel units 10B are aligned in columns, as shown in the schematic diagram Figure 6 As shown, the pixel units in the column direction are distributed as red-green combination, blue-green combination, red-green combination, and blue-green combination, and the pixel units in the row direction are distributed as a red-green combination and a blue-green combination;

Abstract

The invention discloses a pixel structure and a display device. The pixel structure comprises a plurality of pixel units which are arranged in a matrix form. The pixel unit comprises a first sub-pixel and at least two sub-pixels which are adjacent and juxtaposed, wherein organic materials of at least two second sub-pixels are connected. The invention further discloses a display device, comprising a pixel driving circuit and a pixel structure; in a process of forming an organic light-emitting diode through evaporating the organic material; a light emitting area of a single pixel is defined by a metal electrode prepared by a high precision etching technology; the organic materials of at least two adjacent same-color second pixels only adopt one opening on a masking plate to perform evaporation, so that the technical problem that the processing on opening of the masking plate is difficult. The pixel structure and the display device eliminate the technical difficulty of the etching technology after evaporation, enable the same-color sub-pixels to be closely adjacent, improve a yield and realize high definition OLED products.
