Description

A kind of dot structure and adopt the organic light emitting display of this dot structure

The application is that application number is 201310747572.1, and the applying date is on December 31st, 2013, and name is called the divisional application of the application for a patent for invention of " a kind of dot structure and adopt the organic light emitting display of this dot structure ".

Technical field

The present invention relates to organic light emitting display technical field, specifically, is a kind of dot structure and the organic light emitting display that adopts this dot structure.

Background technology

OLED(Organic Light-Emitting Diode, Organic Light Emitting Diode) be active illuminating device.With traditional LCD(Liquid Crystal Display, liquid crystal display) display mode compares, and OLED Display Technique, without backlight, has self luminous characteristic.OLED adopts very thin organic material rete and glass substrate, and in the time having electric current to pass through, organic material will be luminous.Therefore OLED display screen can significantly be saved electric energy, can do lighter and thinnerly, tolerate the more variations in temperature of wide region, and visible angle is larger than LCD display.OLED display is expected to become the flat panel display of future generation after LCD, is one of the maximum technology that receives publicity in current flat panel display.

The colorize method of OLED screen body has many kinds, now comparatively ripe and the OLED colorize technology of successful volume production be OLED evaporation coating technique, it adopts traditional RGB Stripe(RGB strip) arrangement mode carries out evaporation.What wherein picture effect was best is side-by-side(juxtaposition) mode.Side-by-side mode is to have red, green, blue (R, G, B) three sub-pixels (sub-pixel) in a pixel (Pixel) scope, each sub-pixel is all quadrangle, and there are separately independently organic light emission components and parts, it is to utilize evaporation film-forming technology to see through fine metal mask plate (Fine Metal Mask, FMM) at array(array) corresponding location of pixels forms organic emitting components on substrate.Make high PPI(Pixel Per Inch, dpi (dots per inch)) technology of OLED screen body focuses on the fine metal mask plate of meticulous and good mechanical stability, and the key of fine metal mask plate is the arrangement mode of pixel and sub-pixel.

The at present arrangement mode such as seamed (slit), groove (slot), Pentile and IGNIS of industry, but because mask plate (Mask) aperture area has specification lower limit, and be subject to the impact of tolerance (tolerance) for fear of manufacturing process, between the opening of neighbor, need preset clearance (gap) and cause picture element density, as PPI cannot be increased dramatically, and Pixel arrangement is not the reasons such as true colour display screen on true meaning shows, make above scheme can't well solve the problem that picture element density promotes.

Traditional pixel arrangement mode, each pixel is become by R, G, B tri-colour cells respectively.Pixel arrangement mode is as shown in Figure 1 divided into R, G, tri-sub-pixels that are parallel to each other of B in a pixel, and each sub-pixel is all quadrangle, regulates R, G, the corresponding tetragonal size of B sub-pixel according to the difference of corresponding RGB device performance.As shown in Figure 1, pixel region 100 comprises R subpixel area 101, R luminous zone 102, G subpixel area 103, G luminous zone 104, B subpixel area 105 and B luminous zone 106, the region of R shown in figure, G, B sub-pixel and luminous zone area are equal respectively, and when enforcement, area can adjust as required.

Figure 1A and Figure 1B are respectively two kinds of evaporation Mask corresponding to Fig. 1.Wherein, 107,109 in Figure 1A, Figure 1B is Mask blocked area, and the opening of evaporation district opening 108,110 can be two kinds of seam (slit) or grooves (slot).

Figure 1A is slit formula evaporation Mask, and its corresponding metal mask plate openings of sizes is corresponding with the size of sub-pixel.The opening mode main feature of this metal mask plate is that all sub-pixels of same row in screen body share same opening, metal mask plate opening is longer in the longitudinal direction, along with the increase of screen size, the opening length of metal mask plate also needs to increase thereupon, and the non-opening portion between adjacent apertures forms metal rectangular (stripe).

Slit opening mode is for the OLED screen body of low PPI, and on metal mask plate, the spacing of adjacent apertures is larger, and metal is rectangular wider, and the making of metal mask plate and use management are easier to.But this kind of opening mode is in the time of the application of the OLED of high PPI screen body, the pitch smaller of adjacent apertures on fine metal mask plate, metal is rectangular thinner, in use metal is rectangular is easily subject to the impact of magnet plate magnetic line of force direction and is out of shape for metal mask plate, cause different colours material between sub-pixel mutually to pollute and colour mixture, the production yield of product is lower.In addition, this kind of metal mask plate also easy impaired distortion in use, cleaning and keeping process, recycling rate of waterused is not high, because the cost of metal mask plate is high, the screen body cost of making is in this way also higher.

Figure 1B is slot formula evaporation Mask, the opening mode main feature of this kind of metal mask plate is that the position being positioned in slit opening between pixel has increased bridge(connecting bridge), connect adjacent metal rectangular, an original rectangular opening is changed over to multiple open cells.The method makes the metal of metal mask plate rectangular comparatively firm, has solved the rectangular problem that affected by the magnetic line of force and external force and to be out of shape of above-mentioned slit opening mode metal.But considering the long dimensional accuracy of metal mask plate, during for fear of evaporation, sub-pixel is produced to capture-effect, between sub-pixel and bridge, must keep enough distances, the upper and lower length of sub-pixel is dwindled, and has affected the aperture opening ratio of each sub-pixel.

In above-mentioned each mode, the sub-pixel that the each opening on Mask can only corresponding one or one same color, its density of arranging can not improve, thereby resolution just cannot improve.And be subject to the impact of Mask technological level, opening on this Mask can not be too small, because evaporation can produce " shadow effect ", between two luminous zones, also need reserved certain surplus, prevent from producing colour mixture because of " shadow effect ", therefore Mask opening can not do very littlely, otherwise also can have influence on aperture opening ratio.

In the United States Patent (USP) that IGNIS company of Canada is US20110128262 at the publication number of its application, a kind of arrangement mode of pel array has been proposed, but its sub-pixel is still quadrangle separately, just sub-pixel relative position relation is different with slot arrangement mode with slit, and three sub pixels are " product " font and arrange.As shown in Figure 2, pixel region 200 comprises R subpixel area 201, R luminous zone 202, G subpixel area 203, G luminous zone 204, B subpixel area 205, B luminous zone 206.Fig. 2 A and Fig. 2 B are respectively two kinds of evaporation Mask corresponding to the B sub-pixel of Fig. 2, Fig. 2 C is corresponding to the R sub-pixel of Fig. 2 or the evaporation Mask of G sub-pixel, Mask opening is equivalent to a pixel to be divided into two sub-pixels, shadow region 207,209,211 shown in figure is respectively evaporation blocked area, the evaporation opening 208,210 of evaporation B sub-pixel can be slit or slot, evaporation opening 212 is the Mask opening of R or G sub-pixel, a still corresponding sub-pixel, its length and width size is equivalent to the length and width size of a sub-pixel.In this kind of mode, pixel does periodicity level and vertical translation has formed the pel array of row with row.Red relatively large with the aperture pitch of the corresponding metal mask plate of green sub-pixels, can realize to a certain extent high PPI and show.

The result that pixel period is arranged, that blue subpixels in pel array forms straight line and arranges, make corresponding metal mask plate must use the opening mode of aforementioned slit or aforementioned slot, but as mentioned above slit and slot opening mode all exist defect, cause the opening mode of blue metal mask plate in the pel array arrangement mode of IGNIS to have a strong impact on the further lifting of sub-pixel aperture opening ratio and PPI.

In addition, organic light emitting display, the aperture opening ratio of meeting sub-pixel along with the lifting of resolution reduces conventionally, and final result is to cause the work luminance raising of monochrome devices and the lost of life of display screen.Therefore need a kind of new Pixel Design technology badly, ensure R, G, B sub-pixel aperture opening ratio and improve the resolution of shielding body.
