Problems solved by technology

In the case of low grayscale display, because the voltage between the cathode 12 and the anode 17 is small, that is, the electrons are subjected to a small electric field force, the movement of some electrons is more affected by diffusion than by the electric field force. It will easily diffuse to the adjacent sub-pixel area, and migrate to the organic light-emitting layer of the adjacent sub-pixel, and recombine with the holes in the adjacent sub-pixel to emit light, thereby causing crosstalk to the light emission of the adjacent sub-pixel
This causes the color coordinates of adjacent sub-pixels to shift, resulting in an abnormal color cast

Abstract

The present invention discloses an OLED (Organic Light Emitting Diode) device. The device comprises a substrate, the substrate is provided with a plurality of OLED sub pixels, wherein an insulation obstruction body is arranged between each two adjacent OLED sub pixels with different colors, and the obstruction body is configured to block the carrier diffusion between the two OLED sub pixels. The present invention further discloses a display device comprising the OLED device. The luminescence crosstalk between adjacent OLED sub pixels can be avoided, and the color coordinate offset of the OLED sub pixels is avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED device and a display device comprising the OLED device. Background technique [0002] AMOLED (Active Matrix Organic Light Emitting Diode, Active Matrix Organic Light Emitting Diode) display is a self-luminous display using OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) technology. It has the advantages of wide color gamut, high contrast ratio, ultra-thin design and lower power consumption, so it is becoming the first choice for next-generation display technology. [0003] Such as figure 1 As shown, a sub-pixel structure of an AMOLED display includes sequentially stacked cover 1, cathode 12, electron transport layer 13, organic light-emitting layers 141-143, hole transport layer 15, hole injection layer 16, anode 17, array Substrate 18 etc. When a certain voltage is applied between the cathode 12 and the anode 17 , electrons are injected from the cat...
