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 using very thin organic material film laye and glass substrate, when have electric current by when, have
Machine material will light.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 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.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 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 high PPI(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
The key of category mask plate is the arrangement mode of pixel and sub-pixel.
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 is by tolerance(tolerance)Influence, adjacent pixel
Opening between need preset clearance(gap)And causing picture element density, such 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 reason so that above scheme can't solve asking for picture element density lifting well
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 the sub-pixel that R, G, B tri- is parallel to each other, each sub-pixel is in quadrangle, according to correspondence RGB in a pixel
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 as needed can be adjusted during implementation.
Figure 1A and Figure 1B is respectively two kinds of evaporation Mask corresponding to Fig. 1.Wherein, 107,109 in Figure 1A, Figure 1B are
Mask blocked areas, the opening of evaporation area's opening 108,110 can be seam(slit)Or groove(slot)Two kinds.
Figure 1A is that Mask is deposited in slit formulas, 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 longer in the longitudinal direction, with the increase of screen size, and the Opening length of metal mask plate is also needed
Increase, the non-opening portion between adjacent apertures forms metal strip(stripe).
Slit opening modes are for low PPI OLED screen body, and the spacing of adjacent apertures is larger on metal mask plate, gold
Belong to strip wider, the making of metal mask plate and be easier to using management.But such a opening mode is in high PPI OLED screen body
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 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.In addition, such a metal mask plate use, cleaning and management process in also easily by
Damage deformation, recycling rate of waterused is high because the cost of metal mask plate is high, the screen body cost made in this way also compared with
It is high.
Figure 1B is that Mask is deposited in slot formulas, 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 causes the metal strip of metal mask plate more to consolidate, and solves above-mentioned slit openings
The problem of formula metal strip is easily influenceed and deformed by the magnetic line of force and external force.But considering the long dimensional accuracy of metal mask plate,
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
Above and below 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 the sub-pixel of one or one same color, and it is arranged
Cloth density can not be improved, thus resolution ratio can not 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, is prevented 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 its Publication No. applied US20110128262 United States Patent (USP), 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 that two kinds of evaporations 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
Evaporation Mask, Mask openings are divided into two sub-pixels equivalent to by a pixel, shadow region 207 shown in figure, 209,
211 be respectively evaporation blocked area, and the evaporation opening 208,210 of evaporation B sub-pixels can be slit or slot, evaporation opening 212
It is open for the Mask of R or G sub-pixel, still corresponds to a sub-pixel, i.e. length and width chi of its length and width size equivalent to 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.
The result of pixel period arrangement, is the blue subpixels formation straight line arrangement in pel array so that corresponding
Metal mask plate must use foregoing slit or foregoing slot opening mode, but slit and slot is opened as described above
The mouth equal existing defects of mode, cause the serious shadow of opening mode of blue metal mask plate in IGNIS pel array arrangement mode
Sub-pixel aperture opening ratio and PPI further lifting are rung.
In addition, 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 for the operating brightness lifting and display screen for causing monochrome devices.Therefore a kind of new pixel design skill is needed badly
Art, come the resolution ratio for ensureing R, G, B sub-pixel aperture opening ratio and improving screen body.
