Description
Technical field
The present invention relates to pixel arrangements, particularly relate to a kind of for the dot structure of Organic Light Emitting Diode (OLED) display screen, metal mask plate and OLED display screen.
Background technology
Compared with traditional LCD display mode, OLED Display Technique is without backlight.It has self luminous characteristic, adopts very thin organic material rete and glass substrate, and when there being electric current to pass through, organic material will be luminous.Therefore OLED display screen can save significantly on electric energy, it is possible to is made lighter and thinner, tolerates the variations in temperature of wider range than LCD display, and visible angle is bigger.Wherein, the luminescent layer of OLED screen body is typically all and utilizes evaporation film-forming technology to form organic emitting components through fine metal mask plate (finemetalmask, FMM) corresponding location of pixels on array substrate by organic material.
Fine metal mask plate (finemetalmaskFMM) is the key element in evaporation pixel, in general, should there is the problem such as warpage, fracture in fine metal mask plate, it is to avoid cause evaporation rete to swoon out, skew etc. affects the defect of evaporation quality as little as possible.And the arrangement mode of pixel and sub-pixel is to determine whether fine metal mask plate is susceptible to warpage and major cause of failure.That is, the arrangement mode of pixel and the sub-pixel upper mechanical performance determining metal mask plate largely, the mechanical performance of metal mask plate is the upper quality determining evaporation largely.
The arrangement mode (i.e. the opening mode of metal mask plate) of existing pixel mainly has following two:
One, slot (flute profile) mode
Figure 1A shows the traditional pixel arrangements corresponding to slit opening mask plate used in OLED screen curtain, and as shown in Figure 1A, traditional OLED display screen luminescent layer is made up of the pixel cell 2 ' of the multiple lines and multiple rows of the upper arrangement of substrate 1 '.Red (R) 21 ', green (G) 22 ', blue (B) 23 ' three sub-pixels being parallel to each other are included in a pixel cell 2 '.In order to process this pixel arrangements, its corresponding metal mask plate 3 ' is as shown in Figure 1B.
Be can be seen that by Figure 1B, this metal mask plate 3 is to be correspondingly arranged slit opening 31 ' in the position of the sub-pixel 21 ' of a certain color, owing in the arrangement mode of Figure 1A, the sub-pixel 21 ' of same color is that upper and lower para-position is arranged, therefore the slit opening 31 ' of metal mask plate 3 ' also must be arranged in para-position, and this makes metal bridging (bridge) 32 ' between longitudinally adjacent two slit opening 31 ' have the risk of broken string.Also or, because of metal put up a bridge (bridge) tiny, cannot exert a force in the horizontal direction when throwing the net excessive, or because of exert a force excessive and cause metal put up a bridge (bridge) broken string.Meanwhile, the slit opening 31 ' of mask plate 31 ' needs corresponding to predetermined location of pixels, according to this kind of pixel arrangement mode existing, mask plate 31 ' and sub-pixel area bit space can be reduced, it is possible to produce lack the defect of color or colour mixture.
Two, strip (banding) mode
Fig. 2 A shows the traditional pixel arrangements corresponding to banding Opening mask plate used in OLED screen curtain, as shown in Figure 2 A, at substrate 1 " a pixel cell 2 " in include red (R) 21 ", green (G) 22 ", blue (B) 23 " three sub-pixels being parallel to each other.In order to form this pixel arrangements, its corresponding metal mask plate 3 ' is as shown in Figure 2 B.
By Fig. 2 B it can be seen that this metal mask plate 3 " be the sub-pixel 21 in a certain color " position be correspondingly arranged banding opening 31 ", banding opening 31 " elongated, it is to avoid the metal of the mask of slit opening 31 ' put up a bridge 32 ' broken string risk.But, banding opening 31 " need to maintain its rectilinearity and flatness, more difficult realization on fine metal mask.
In sum, existing metal mask plate has shortcoming as above, particularly carries under high-resolution demand at needs, existing pixel arrangement mode and metal mask plate be all difficult under high-resolution ensure evaporation quality demand.It is, therefore, desirable to provide the metal mask plate of a kind of dot structure with new arrangement and correspondence and OLED display screen, to solve prior art Problems existing.
