Description of drawings
Fig. 1 is an OLED structural representation of the present invention;
Fig. 2 comprises the regional area sketch map of a plurality of mark parts for the present invention.
Embodiment
Through specific embodiment the present invention is done further detailed description below.
Fig. 1 is the OLED structural representation, comprises viewing area A on the substrate 1, both sides go between regional B1, B2, and downside lead-in wire zone C, IC (integrated circuit) nation decides region D, the mark part 2 of A both sides, viewing area.
Fig. 2 is the regional area sketch map that comprises a plurality of mark parts, and viewing area A is made up of the pixel 34 of the plural row and column of proper alignment, and each pixel comprises luminescent layer, anode and negative electrode 35, and anode and negative electrode lay respectively at the both sides of luminescent layer.Insulating barrier 31 and insulated column layer 32 are opened each pixel obstruct between neighbor pixel.
The viewing area, the negative electrode of each row pixel links to each other, and line direction extends to side go between regional B1, B2 along the pixel place, connects with the first corresponding lead-in wire 33.First lead-in wire 33 comprises clinch 331 and connecting portion 332, and the negative electrode that wherein extends is connected with the clinch 331 of first lead-in wire.Negative electrode i.e. first electrode.The anode of each row pixel links to each other, and extends to downside lead-in wire zone C from the downside of viewing area along row pixel direction, with the second lead-in wire overlap joint.Anode i.e. second electrode.Negative electrode 35 is connected with clinch, is to connect through the mode that superposes, and this mode is called overlap joint again.Distance between adjacent two mark parts equals the distance of two capable pixels of correspondence along column direction.
In side lead-in wire zone, be provided with a plurality of mark parts 2, mark part extends along the pixel column direction, as can be seen from the figure, in side goes between regional B1 and B2, has a row mark part respectively, and the mark part corresponding pixel points is expert at.This corresponding relation: can be all corresponding one-row pixels point of each mark part; Promptly there are how many row pixels what mark parts are just arranged; All be distributed with the mark part of corresponding line number at go between regional B1 and B2 of side; Like the viewing area of 128 row * 64 row, all have 64 mark parts at go between regional B1 and B2 of side; It also can be the corresponding odd-numbered line pixel of a part of mark part; The corresponding even number line pixel of part mark part; Wherein odd-numbered line corresponding identification portion is positioned at the side regional B1 that goes between, and even number line corresponding identification portion is positioned at the side regional B2 that goes between, like the viewing area of 128 row *, 64 row; Wherein 32 even number line corresponding identification portions are positioned at the side regional B1 that goes between, and 32 odd-numbered line corresponding identification portions are positioned at the side regional B2 that goes between; Also can be the corresponding triplex row pixel of mark part, then all have at least 14 mark parts at go between regional B1 and B2 of side; And the like, in order to search pixel place line position fast, mark part can corresponding 4 row pixels or more, repeat no more.
Above-mentioned corresponding relation, the distance between the adjacent mark part are definite value b, and the b value should equate with the distance between the pixel of the pairing line number of mark part.Be the mark part of corresponding one-row pixels point, the distance between its adjacent mark part should be along the length of a pixel of column direction; The mark part of corresponding two row pixels, the distance between its adjacent mark part should be along the length of two pixels of column direction; The mark part of corresponding triplex row pixel, the distance between its adjacent mark part should be along the length of three pixels of column direction, and the like.
Mark part is made up of a plurality of identification points 21, and identification point is positioned on the straight line of mark part place, and the distance between the identification point of mark part is a.Identification point is positioned on the clinch, can say in the time of preparation that clinch and identification point prepare simultaneously.
The distance of each mark part and viewing area is c, and c is greater than the distance between clinch and the viewing area.The distance of mark part and viewing area be meant mark part with near its length of pixel, the distance between clinch and the viewing area be meant clinch with near its length of pixel.
When the problem pixel point is positioned, belong to this mark part place which mark part of row according to mark part or identification point position and this mark part, confirm that this pixel belongs to line number.In the detection problem pixel point is located fast.The setting of mark part and identification point, the scope that takies overlap and/or clinch is less, is merely one by one little round dot, can not influence first electrode and first lead-in wire overlap joint at clinch.
A kind of organic electroluminescent module comprises, drive unit, and FPC also has above-mentioned organic electroluminescence device.And a kind of mobile communication equipment, comprise communicator and display unit, this organic electroluminescent module of said display unit.
Though the present invention is to disclose as above than preferable embodiment; Yet it is not in order to limit the present invention; Anyly be familiar with this technological personage, do not breaking away from the spirit and scope of the present invention, when doing various changes and retouching; Therefore, protection scope of the present invention is as the criterion when the claim with application defines.
