Abstract
The utility model provides a PMOLED tiled display screen, comprising scanning electrodes connected to a display area pixel row and data electrodes connected to a display area pixel column. Contact holes for connecting the scanning electrodes to a cathode of the PMOLED are disposed at two sides of a display area, and the data electrodes are used for inputting a data signal of a display area pixel. The beneficial effects of the PMOLED tiled display screen are that, the PMOLED tiled display screen is suitable for large-size high resolution tiled PMOLEDs, solves the problem that a function layer of the large-size high resolution tiled PMOLED requires for twice evaporation of odd and even columns, and the fineness of the display screen can be improved. Therefore, light emission is normally performed after positive and negative poles of an OLED pixel unit are electrified. Since the contact holes are disposed at the two sides of the display area, the OLED function layer can be in one-time evaporation. What's more, the scanning electrodes can be designed to be finer, so that the fineness of the display screen can be improved.
Description
Technical field
The utility model OLED Display Technique field, relates to multi-screen connected connection technology, particularly a kind of PMOLED mosaic display screen.
Background technology
OLED (Organic Light Emitting Diode Organic Light Emitting Diode) is Display Technique of new generation, and it,, by luminous organic material being clipped between transparent anode and metallic reflection negative electrode, applies voltage to organic film and carry out luminous.It is known as by industry with many merits such as frivolous, active illuminating, fast-response speed, wide viewing angle, rich color, high brightness, low-power consumption and high-low temperature resistants is the third generation Display Technique after liquid crystal display (LCD), be applied in more and more in the portable products such as smart mobile phone, digital camera, panel computer at present, there are boundless market prospects.
But PMOLED display is wherein owing to being that passive type drives, and each pixel cannot maintain drive current in certain displaying time, can only drive with peak current, thereby cause its size to do large words power consumption, can sharply increase.Cannot realize large picture and high-resolution shows.
For PMOLED, splice design and can overcome this problem, but will accomplish seamless splicedly just the scan line of PMOLED need to be built in to viewing area, in viewing area, utilize contact hole to connect the auxiliary electrode of scan line and the negative electrode of OLED.For the auxiliary electrode of scan line is contacted well with OLED negative electrode, need to guarantee suitable contact hole area.While there is contact hole in viewing area, because OLED has a plurality of functional layer film, this film is insulating material, in PMOLED manufacturing process, can before OLED negative electrode evaporation, cover contact hole, cause cannot contacting between the auxiliary electrode of scan line and OLED negative electrode, therefore need to, when OLED functional layer evaporation, adopt odd even mode evaporation to solve this problem for twice.So not only increased the complexity of technique, also wasted expensive organic material, more seriously the existence of contact hole has reduced the fineness of display screen.Be illustrated in figure 1 existing PMOLED mosaic display screen structural representation: drive IC 101 is sent image video signal, be connected to respectively every a line of viewing area by scan electrode 102, data electrode 103 is connected to each row of viewing area.Scan electrode is connected by the contact hole 105 of inside, viewing area and the negative electrode of PMOLED, and 103 of data electrodes are directly connected to pixel electrode 104.So just can be normally luminous after the energising of the both positive and negative polarity of OLED pixel cell.The words of this design are because contact hole 105 is positioned at inside, viewing area, need to be in evaporation OLED functional layer first evaporation odd column, and then evaporation even column, not only complex process, also wasted expensive organic material, contact hole has also reduced the fineness of display screen simultaneously.
Utility model content
The purpose of this utility model is in order to solve in PMOLED screen splicing complex process and organic material to be wasted to large problem, having proposed a kind of PMOLED mosaic display screen.
The technical solution of the utility model is: a kind of PMOLED mosaic display screen, comprise the scan electrode that is connected to viewing area pixel column and the data electrode that is connected to viewing area pixel column, it is characterized in that, the contact hole being connected with the negative electrode of PMOLED for scan electrode is positioned at the both sides of viewing area, and data electrode is for inputting the data-signal of viewing area pixel.
Further, described display screen also comprises the drive IC for generation of image video signal.
The beneficial effects of the utility model: the present invention is applicable to large scale high-resolution splicing PMOLED, have not only solved the problem that the functional layer of current large scale high-resolution splicing PMOLED need to minute twice evaporation of parity column, can also improve the fineness of display screen.So just can be normally luminous after the energising of the both positive and negative polarity of OLED pixel cell.And because contact hole is positioned at both sides, viewing area, OLED functional layer can disposable evaporation, and scan electrode can design thinner, can improve the fineness of display screen.
Accompanying drawing explanation
Fig. 1 is existing PMOLED mosaic display screen structural representation;
Fig. 2 is PMOLED mosaic display screen structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further elaborated.
As shown in Figure 2, the PMOLED mosaic display screen of the present embodiment, comprises the scan electrode 202 that is connected to viewing area pixel column and the data electrode 203 that is connected to viewing area pixel column.The contact hole 205 being connected with the negative electrode of PMOLED for scan electrode is positioned at the both sides of viewing area, and data electrode is directly connected to pixel electrode 204 for inputting the data-signal of viewing area pixel.Described display screen also comprises the drive IC 201 for generation of image video signal.
Compare existing PMOLED mosaic display screen, splicing PMOLED method for designing drive IC 201 of the present invention is sent image video signal, is connected to respectively every a line of viewing area by scan electrode 202, and data electrode 203 is connected to each row of viewing area.Scan electrode is connected by the contact hole 205 of both sides, viewing area and the negative electrode of PMOLED, and 203 of data electrodes are directly connected to pixel electrode 204.So just can be normally luminous after the energising of the both positive and negative polarity of OLED pixel cell.The words of this design are because contact hole 205 is positioned at both sides, viewing area, and OLED functional layer can disposable evaporation, and 202 scan electrodes can design thinner, can improve the fineness of display screen.
Those of ordinary skill in the art will appreciate that, embodiment described here is in order to help reader understanding's principle of the present utility model, should be understood to that protection range of the present utility model is not limited to such special statement and embodiment.Those of ordinary skill in the art can make various other various concrete distortion and combinations that do not depart from the utility model essence according to disclosed these technology enlightenments of the utility model, and these distortion and combination are still in protection range of the present utility model.
