Description
Technical field
The present invention relates to a kind of array of organic light emitting pixels, relate in particular to the other array of organic light emitting pixels that the instruction district is arranged of a kind of pixel region.
Background technology
Organic luminescent device (Organic Light Emitting Diode is abbreviated as OLED) is a kind of novel flat-panel display device.Traditional LCD (LCD), self can not be luminous, needs backlight.And Organic Light Emitting Diode (OLED) device itself has lighting function, is a kind of selfluminous element, and therefore, Organic Light Emitting Diode (OLED) device more can be done frivolously than LCD, and more power saving.In addition, Organic Light Emitting Diode (AMOLED) device has characteristics such as reaction speed is very fast, contrast is higher, the visual angle is wider.
Utilizing ink-jet printing process to make luminescent layer is organic material to be sprayed in the pixel region form, because there is crucial influence the dry time to the uniformity of film forming, and the material that sprays is inconsistent drying time, so can influence the uniformity of organic luminous layer.And when being sprayed at organic material in the pixel region, can occur the dislocation and cause the colour mixture problem, influenced the making yield.
In view of this, how to design a kind of array of organic light emitting pixels, both can improve the uniformity of organic luminous layer, can avoid again because the colour mixture problem that the spraying dislocation causes is the problem that the insider needs solution badly.
Summary of the invention
At array of organic light emitting pixels in the prior art and since material drying time the inconsistent film forming that causes inhomogeneities, and the colour mixture problem that causes of the dislocation during sprayed on material provides a kind of array of organic light emitting pixels.
According to an aspect of the present invention, provide a kind of array of organic light emitting pixels, having comprised: glass substrate, a plurality of pixel region and virtual area.Wherein, a plurality of pixel regions are positioned on the glass substrate, and each pixel region comprises: pixel electrode, isolation structure and first barricade.Isolation structure is positioned on the glass substrate, and part is covered in the edge of anode.Virtual area is between adjacent two pixel regions.
Preferably, the manufacturing materials of isolation structure is an inorganic material.
Preferably, the manufacturing materials of first barricade is an organic material.
Preferably, array of organic light emitting pixels more comprises luminescent layer, is positioned on a plurality of pixel regions.
Preferably, luminescent layer forms by ink-jet printing process.
Preferably, virtual area is between adjacent two first barricades of adjacent two pixel regions.
Preferably, can have second barricade between adjacent first barricade of adjacent two pixel regions.
Preferably, second barricade forms a plurality of virtual areas with the region separation between adjacent two pixel regions.
Preferably, the manufacturing materials of second barricade is identical with the manufacturing materials of first barricade.
Preferably, can spray printing ink or pure solution to virtual area.
Advantage of the present invention is: the pixel region side in array of organic light emitting pixels has increased virtual area, can delay the drying time of material, makes the film of formation have higher uniformity.In addition, can also solve the colour mixture problem that causes owing to dislocation when utilizing ink-jet printing process to spray, improve the efficient of processing procedure.
Description of drawings
The reader will become apparent various aspects of the present invention after the reference accompanying drawing has been read the specific embodiment of the present invention.Wherein,
Fig. 1 shows the profile of the array of organic light emitting pixels of prior art manufacturing;
Fig. 2 shows the profile of the array of organic light emitting pixels of making according to the present invention.
Embodiment
With reference to the accompanying drawings, the specific embodiment of the present invention is described in further detail.
Fig. 1 shows the profile of prior art array of organic light emitting pixels.With reference to Fig. 1, array of organic light emitting pixels comprises glass substrate 100 and a plurality of pixel regions 1.Wherein, a plurality of pixel regions 1 are positioned on the glass substrate 100, and each pixel region 1 comprises: pixel electrode 110, isolation structure 120 and first barricade 130.Pixel electrode 110 is positioned on the glass substrate 100, and isolation structure 120 also is positioned on the glass substrate 100, and has part to be covered in the edge of pixel electrode 110.First barricade 130 is between two neighbor districts 1.Utilizing ink-jet printing process when pixel region 1 spraying organic material forms luminescent layer (not indicating),, therefore can influence the uniformity of film because the drying time of material is inconsistent.And when forming luminescent layer or barricade, can misplace, thereby cause the colour mixture problem with the nozzle sprayed on material.
Fig. 2 shows the profile according to array of organic light emitting pixels of the present invention.With reference to Fig. 2, array of organic light emitting pixels comprises: glass substrate 200, pixel region 1 and virtual area 2.Wherein, pixel region 1 is positioned on the glass substrate, comprising: pixel electrode 210, isolation structure 220 and first barricade 230.In the present embodiment, isolation structure 220 usefulness inorganic material are made, and first barricade 230 is to be made by organic material.Wherein, pixel electrode 210 all is positioned on the glass substrate 200 with isolation structure 220, and isolation structure 220 parts are covered in the edge of pixel electrode 210.A plurality of pixel regions 1 on the glass substrate 200 define with a plurality of first barricades 230.In the present embodiment, array of organic light emitting pixels also comprises luminescent layer (not indicating), and luminescent layer is positioned on the pixel region 1, is to utilize ink-jet printing process to spray organic material in pixel region 1 to form.
Continuation is with reference to Fig. 2, and virtual area 2 is between two neighbor districts 1, and virtual area 2 is between adjacent two first barricades 230 of adjacent two pixel regions 1.When utilizing nozzle, can deliberately spray into printing ink or pure solution at virtual area 2 places like this, play a cushioning effect, to reduce because of the inconsistent inhomogeneities that causes film of ink setting time in the spraying process in the organic material luminescent layer of pixel region 1 spraying.And, when forming the luminescent layer and first barricade 230, can contraposition be forbidden or the solution sputter with the nozzle sprayed on material, virtual area 2 between adjacent like this two pixel regions 1 can also be accommodated because spray printing ink or the pure solution that misplaces or sputter out, thus the colour mixture problem between the pixel region of avoiding causing thus 1.In a further embodiment, between adjacent two pixel regions 1 second barricade can be arranged, second barricade becomes a plurality of virtual areas with the region separation between the neighbor district.The manufacturing materials of second barricade is identical with the manufacturing materials of first barricade, is organic material also.
Adopt the present invention, can delay to reduce drying time inhomogeneities because of the inconsistent film that causes of ink setting time in the spraying process by virtual area, the solution that can also utilize virtual area to accommodate the spraying dislocation is avoided the colour mixture problem that causes thus.
Above, describe the specific embodiment of the present invention with reference to the accompanying drawings.But those skilled in the art can understand, and under situation without departing from the spirit and scope of the present invention, can also do various changes and replacement to the specific embodiment of the present invention.These changes and replace all drop in claims of the present invention institute restricted portion.
