Description

A kind of dot structure and the OLED using the dot structure

The application is Application No. 201310747572.1, and the applying date is on December 31st, 2013, a kind of entitled " pixel The divisional application of the application for a patent for invention of structure and the OLED using the dot structure ".

Technical field

The present invention relates to organic light emitting display technical field, specifically, it is a kind of dot structure and uses the pixel knot The OLED of structure.

Background technology

OLED（Organic Light-Emitting Diode, Organic Light Emitting Diode）It is active luminescent device.With biography The LCD of system（Liquid Crystal Display, liquid crystal display）Display mode is compared, and OLED Display Techniques are without backlight Lamp, with self luminous characteristic.OLED uses very thin organic material film laye and glass substrate, when there is electric current to pass through, has Machine material will light.Therefore OLED display screen can save significantly on electric energy, can be made it is lighter and thinner, it is more resistance to than LCD display By the temperature change of wider range, and visible angle is bigger.OLED display is expected to turn into the flat board of future generation after LCD Display Technique, is one of the most technologies that attract attention in current flat panel display.

The colorization method of OLED screen body has many kinds, now the OLED colorization skills of the more ripe and volume production that succeeded Art is OLED evaporation coating techniques, and it uses traditional RGB Stripe（RGB stripe shape）Arrangement mode is deposited with.Wherein picture effect Most preferably side-by-side（Juxtaposition）Mode.Side-by-side modes are in a pixel（Pixel）In the range of have Red, green, blue（R、G、B）Three sub-pixels（sub-pixel）, each sub-pixel is in quadrangle, and each has and independent have Machine emitting components, it is to pass through fine metal mask plate using evaporation film-forming technology（Fine Metal Mask, FMM） array（Array）Corresponding location of pixels forms organic emitting components on substrate.Make PPI high（Pixel Per Inch, point Per inch）The technology of OLED screen body focuses on the fine metal mask plate of fine and good mechanical stability, and fine is golden Belong to the arrangement mode that it is critical only that pixel and sub-pixel of mask plate.

Current industry is seamed（slit）, groove（slot）, the arrangement mode such as Pentile and IGNIS, but due to mask plate （Mask）Aperture area has lower specification limit, and in order to avoid manufacturing process receives tolerance（tolerance）Influence, adjacent pixel Opening between need preset clearance（gap）And causing picture element density, such as PPI cannot be increased dramatically, and pixel arrangement It is not that true colour display screen on true meaning such as shows at the reason so that above scheme can't well solve asking for picture element density lifting Topic.

Traditional pixel arrangement mode, each pixel respectively by the colour cell of R, G, B tri- into.Pixel arrangement side as shown in Figure 1 Formula, is divided into tri- sub-pixels being parallel to each other of R, G, B in a pixel, and each sub-pixel is in quadrangle, according to correspondence RGB The difference of device performance come adjust R, G, B sub-pixel correspondence quadrangle size.As shown in figure 1, pixel region 100 includes R Pixel region 101, R luminous zones 102, G sub-pixel region 103, G luminous zones 104, B subpixel areas 105 and B luminous zones 106, The region of R, G, B sub-pixel shown in figure and luminous zone area difference are equal, and area can be adjusted as needed during implementation.

Figure 1A and Figure 1B are respectively two kinds of evaporation Mask corresponding to Fig. 1.Wherein, 107,109 in Figure 1A, Figure 1B are Mask blocked areas, the opening for being deposited with area opening 108,110 can be seam（slit）Or groove（slot）Two kinds.

Figure 1A is that slit formulas are deposited with Mask, and its corresponding metal mask plate openings of sizes is relative with the size of sub-pixel Should.The opening mode of the metal mask plate is mainly characterized by sharing same opening in all sub-pixels for shielding internal same row, Metal mask plate opening is more long in the longitudinal direction, and with the increase of screen size, the Opening length of metal mask plate is also needed Increase, the non-opening portion between adjacent apertures forms metal strip（stripe）.

For the OLED screen body of low PPI, the spacing of adjacent apertures is larger on metal mask plate for Slit opening modes, gold Category strip is wider, the making of metal mask plate and is easier to using management.But this kind of opening mode is in the OLED screen body of PPI high Using when, the spacing of adjacent apertures diminishes on fine metal mask plate, and metal strip is thinner, and metal mask plate is using process Middle metal strip is easily influenceed and is deformed by magnet plate magnetic line of force direction, and different colours material mutually pollutes between causing sub-pixel And colour mixture, the production yield of product is relatively low.Additionally, this kind of metal mask plate is also easily received in use, cleaning and management process Damage deformation, recycling rate of waterused is not high because the high cost of metal mask plate, the screen body cost for making in this way also compared with It is high.

Figure 1B is that slot formulas are deposited with Mask, and the opening mode of this kind of metal mask plate is mainly characterized by slit openings middle position Position between pixel increased bridge（Connecting bridge）, adjacent metal strip is connected, an original strip opening is changed Become multiple open cells.The method causes that the metal strip of metal mask plate is more consolidated, and solves above-mentioned slit openings The problem that formula metal strip is easily influenceed and deformed by the magnetic line of force and external force.But in consideration metal mask plate dimensional accuracy long, Shadowing effect is produced to sub-pixel during in order to avoid evaporation, enough distances, sub-pixel must be kept between sub-pixel and bridge Upper and lower length reduction, and have impact on the aperture opening ratio of each sub-pixel.

In above-mentioned each mode, each opening on Mask can only correspond to one or one sub-pixel of same color, its row Cloth density can not be improved, thus resolution ratio cannot just be improved.And influenceed by Mask technological levels, the opening on this Mask is not Can be too small, because evaporation can be produced " shadow effect ", reserved certain surplus is also needed between two luminous zones, prevent because " cloudy Shadow effect " and produce colour mixture, therefore Mask opening can not be made very small, otherwise also affect aperture opening ratio.

Canadian IGNIS companies are in the United States Patent (USP) of its Publication No. applied US20110128262, it is proposed that a kind of The arrangement mode of pel array, but its sub-pixel is still in each quadrangle, simply sub-pixel relative position relation and slit Different with slot arrangement modes, three sub-pixels are arranged in " product " font.As shown in Fig. 2 pixel region 200 includes R sub-pixels Region 201, R luminous zones 202, G sub-pixel region 203, G luminous zones 204, B subpixel areas 205, B luminous zones 206.Fig. 2A and Fig. 2 B are respectively two kinds of evaporation Mask of the B sub-pixels corresponding to Fig. 2, and Fig. 2 C are the R sub-pixels or G sub-pixel corresponding to Fig. 2 Evaporation Mask, Mask openings are divided into two sub-pixels equivalent to by a pixel, shadow region 207 shown in figure, 209, 211 are respectively evaporation blocked area, and the evaporation opening 208,210 for being deposited with B sub-pixels can be slit or slot, evaporation opening 212 For the Mask of R or G sub-pixel is open, a sub-pixel, i.e. its length and width size are still corresponded to equivalent to a length and width chi for sub-pixel It is very little.In this kind of mode, pixel does periodicity level and vertical translation forms the pel array of row and column.Red and green The opening spacing of the corresponding metal mask plate of pixel is relatively large, can to a certain extent realize that PPI high shows.

The result of pixel period arrangement, is that the blue subpixels in pel array form straight line arrangement so that corresponding Metal mask plate must using foregoing slit or foregoing slot opening mode, but as described above slit and slot open The mouth equal existing defects of mode, cause the serious shadow of opening mode of blue metal mask plate in the pel array arrangement mode of IGNIS The further lifting of sub-pixel aperture opening ratio and PPI is rung.

Additionally, organic light emitting display, it will usually the aperture opening ratio reduction of sub-pixel with the lifting of resolution ratio, finally Result is the lost of life of the operating brightness lifting and display screen for causing monochrome devices.Therefore a kind of new pixel design skill is needed badly Art come ensure R, G, B sub-pixel aperture opening ratio and improve screen body resolution ratio.
