Abstract
The invention discloses an OLED panel. The OLED panel comprises a pixel definition layer, wherein a plurality of pixel areas are arranged on the pixel definition layer; a spacer region is arranged between every two adjacent pixel areas; each pixel definition layer internally comprises a plurality of spacer plates arranged on the spacer regions between every two adjacent pixel areas of different types further; and a gap is formed between every two adjacent spacer plates, and the spacer plates are arranged in a staggered manner. By adopting the spacer plates provided with gaps adopted in the OLED panel disclosed by the invention, the diffusion of an evaporation airflow in the evaporation process can be effectively reduced or avoided; and moreover, due to the fact that the gaps are formed among the different spacer plates, after the OLED panel is packaged, a cathode part corresponding to the gap part can also work normally even if the cathode in the upper surfaces of the spacer plates is extruded and abraded to cause that the impedance of the cathodes is increased, so that the abrasion degree of the whole cathode in the OLED panel is effectively retarded.
Description
Technical field
The present invention relates to OLED Display Technique field, particularly relate to a kind of oled panel.
Background technology
Along with the development of Organic Light Emitting Diode (OrganicLight-EmittingDiode, OLED) technology, the features such as the characteristics of luminescence that OLED is good, low energy consumption, make OLED be widely applied in display, lighting field.
At present, the principle of luminosity of oled panel based on luminous organic material coating wherein, when have electric current by time, this luminous organic material coating is luminous.Specifically: as shown in Figure 1, for a kind of cutaway view of oled panel, wherein, pixel defining layer 10 is fixedly installed the pixel region for sending primaries: blue light (Blue, B) pixel region 101, green glow (Green, G) pixel region 102, ruddiness (Red, R) pixel region 103, adopt high accuracy technique of counterpoint, from the opening 201 of mask plate 20, luminous organic material is plated to surface, corresponding pixel region (wherein in evaporation mode, luminous organic material comprises trichromatic luminous organic material, also be, red-light organic luminous material, green organic luminescence, blue light organic luminescent material), form corresponding pixel.But in the process of evaporation, evaporation air-flow is also uncontrollable, for the evaporation air-flow of a certain pixel region, may diffuse to other pixel regions, thus cause colour mixture, this will affect the final display effect of oled panel.
In prior art, in order to reduce or avoid occurring in evaporate process the mixed color phenomenon of luminous organic material, two kinds of modes are proposed:
Under a kind of mode, the width reducing pixel region makes the distance between pixel region increase, thus reduces the degree of colour mixture, particularly, as shown in figs. 2 a and 2b, the spacing of pixel region is increased to L ' from L.
Under another kind of mode, as shown in Figure 3 a, the interval region between each pixel region of oled panel arranges bar shaped interval insulant (PhotoSpacer, PS) post (or plate), or as shown in Figure 3 b, link up and PS post is set, to stop evaporation air-flow, prevent colour mixture.
But, for above-mentioned two kinds of modes of the prior art, all there is certain defect:
For first kind of way, although add the spacing between pixel region by the mode reducing pixel sector width, the mode reducing pixel sector width will affect the life-span of oled panel.
For the second way, although the effect stopping evaporation Diffusion of gas stream can be played, but when actual package, may due to the relative movement between substrate and cover plate, separating material stock column is caused to move and target causes wearing and tearing towards the one side of cover plate, the cathode impedance of whole interval insulant columnar region is strengthened, thus the display effect of oled panel is impacted.
Summary of the invention
The embodiment of the present invention provides a kind of Organic Light Emitting Diode, in order to solve the problem of existing oled panel colour mixture in evaporate process.
The invention provides a kind of oled panel, comprising: pixel defining layer, described pixel defining layer is provided with some pixel regions, between adjacent two pixel regions, there is interval region, also comprise in described pixel defining layer and be arranged at adjacent and be the some space bars on the interval region between different classes of two pixel regions, between adjacent two space bars, be provided with gap and described space bar Heterogeneous Permutation;
Wherein, described adjacent two pixel regions are different classes of pixel region.
