Description

A kind of dot structure and the organic light emitting display 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 organic light emitting display using the dot structure ".

Technical field

The present invention relates to organic light emitting display technical fields, specifically, are a kind of dot structure and use the pixel knot The organic light emitting display 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 technologies are without backlight Lamp has self luminous characteristic.OLED use very thin organic material film laye and glass substrate, when have electric current by when, have Machine material will shine.Therefore OLED display screen can save significantly on electric energy, can be made lighter and thinner, more resistance to than LCD display By the temperature change of wider range, and visible angle bigger.OLED display is expected to become the next-generation tablet after LCD Display technology is one of the most technology that attracts attention in current flat panel display.

There are many kind, the present more mature and volume production that succeeded OLED colorization skills for the colorization method of OLED screen body Art is OLED evaporation coating techniques, uses traditional RGB Stripe（RGB stripe shape）Arrangement mode is deposited.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 is each had with independent Machine emitting components, it is to penetrate 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 high PPI（Pixel Per Inch, point Per inch）The technology of OLED screen body focuses on fine and good mechanical stability fine metal mask plate, and fine is golden The key for belonging to mask plate is the arrangement mode of pixel and sub-pixel.

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

Traditional pixel arrangement mode, each pixel respectively by tri- colour cell of R, G, B into.Pixel arrangement side as shown in Figure 1 Formula is divided into tri- sub-pixels being mutually parallel of R, G, B in a pixel, and each sub-pixel is in quadrangle, according to corresponding RGB The difference of device performance adjusts the size that R, G, B sub-pixel correspond to quadrangle.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 as needed can adjust during implementation.

Figure 1A and Figure 1B is respectively two kinds of vapor deposition Mask corresponding to Fig. 1.Wherein, 107,109 in Figure 1A, Figure 1B are Mask blocked areas, the opening of vapor deposition area's opening 108,110 can be seam（slit）Or slot（slot）Two kinds.

Mask is deposited for slit formulas in Figure 1A, and corresponding metal mask plate openings of sizes is opposite with the size of sub-pixel It 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 longer in the longitudinal direction, and with the increase of screen size, the Opening length of metal mask plate also needs It increases, the non-opening portion between adjacent apertures forms metal strip（stripe）.

Slit opening modes are for the OLED screen body of low PPI, and the spacing of adjacent apertures is larger on metal mask plate, gold It is wider to belong to strip, the making of metal mask plate and is easier to using management.But such opening mode is in the OLED screen body of high PPI In application, the spacing of adjacent apertures becomes smaller on fine metal mask plate, metal strip is thinner, and metal mask plate is using process Middle metal strip is easily influenced by magnet plate magnetic line of force direction and deformed, and different colours material mutually pollutes between causing sub-pixel And colour mixture, the production yield of product are relatively low.In addition, such metal mask plate use, clean and management process in also easily by Damage deformation, recycling rate of waterused is not high because metal mask plate is of high cost, the screen body cost that makes in this way also compared with It is high.

Mask is deposited for slot formulas in Figure 1B, and the opening mode of this kind of metal mask plate is mainly characterized by slit opening middle positions Position between pixel adds bridge（Connecting bridge）, adjacent metal strip is connected, an original strip opening is changed Become multiple open cells.The method so that the metal strip of metal mask plate is more firm, solves above-mentioned slit opening sides The problem of formula metal strip is easily influenced by the magnetic line of force and external force and deformed.But considering the long dimensional accuracy of metal mask plate, In order to avoid generating shadowing effect to sub-pixel during vapor deposition, enough distances, sub-pixel must be kept between sub-pixel and bridge Upper and lower length reduction, and affect the aperture opening ratio of each sub-pixel.

In above-mentioned each mode, each opening on Mask can only correspond to the sub-pixel of one or one same color, row Cloth density cannot improve, thus resolution ratio can not just improve.And influenced by Mask technological levels, the opening on this Mask is not Can be too small, since vapor deposition can generate " shadow effect ", reserved certain surplus is also needed between two luminous zones, is prevented because " cloudy Shadow effect " and generate 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 each in quadrangle, is 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 that two kinds of vapor depositions Mask, Fig. 2 C of the B sub-pixels for corresponding to Fig. 2 are the R sub-pixels or G sub-pixel corresponding to Fig. 2 Vapor deposition Mask, Mask openings are equivalent to is divided into two sub-pixels by a pixel, shadow region 207 shown in figure, 209, 211 be respectively vapor deposition blocked area, and the vapor deposition opening 208,210 of vapor deposition B sub-pixels can be slit or slot, vapor deposition opening 212 It is open for the Mask of R or G sub-pixel, still corresponds to a sub-pixel, is i.e. its length and width dimensions are equivalent to the length and width ruler of a 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 realize that high PPI is shown to a certain extent.

Pixel period arrangement as a result, being that blue subpixels in pel array form straight line arrangement so that it is corresponding Metal mask plate must use 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 Sub-pixel aperture opening ratio and the further promotion of PPI are rung.

In addition, organic light emitting display, it will usually which the aperture opening ratio of sub-pixel reduces with the promotion of resolution ratio, finally The result is that cause the operating brightness promotion of monochrome devices and the lost of life of display screen.Therefore there is an urgent need for a kind of new pixels to design skill Art, come the resolution ratio for ensureing R, G, B sub-pixel aperture opening ratio and improving screen body.
