Description
Technical field
The present invention relates to pixel arrangements, more particularly to a kind of picture for being used for Organic Light Emitting Diode (OLED) display screen
Plain structure, metal mask plate and OLED display screen.
Background technique
Compared with traditional LCD display mode, OLED display technology is not necessarily to backlight.It is adopted with self luminous characteristic
With very thin organic material film laye and glass substrate, when a current passes through, organic material will shine.Therefore OLED is shown
Screen can save significantly on electric energy, can be made lighter and thinner, than the temperature change of LCD display tolerance wider range, Er Qieke
Angle is bigger.Wherein, the luminescent layer of OLED screen body is typically all to pass through organic material using evaporation film-forming technology through high-precision
Thin metal mask plate (fine metal mask, FMM) corresponding location of pixels on array substrate forms organic light emission member device
Part.
Fine metal mask plate (fine metal mask FMM) is the key element being deposited in pixel, in general, essence
The problems such as warpage, fracture, should occur as little as possible for thin metal mask plate, avoid that vapor deposition film layer is dizzy the influences such as to be opened, deviate and be deposited
The defect of quality.And the arrangement mode of pixel and sub-pixel is to determine whether fine metal mask plate is easy to happen warpage and fracture
The main reason for.That is, the arrangement mode of pixel and sub-pixel largely determines the mechanical performance of metal mask plate, metal
The mechanical performance of mask plate largely determines the quality of vapor deposition.
There are mainly two types of for the arrangement mode (i.e. the opening mode of metal mask plate) of existing pixel:
One, slot (flute profile) mode
Figure 1A shows the pixel arrangements corresponding to slit opening mask plate traditional used in OLED screen curtain, such as
Shown in Figure 1A, traditional OLED display screen luminescent layer is made of the pixel unit 2 ' of the multiple lines and multiple rows arranged on substrate 1 '.One
It include red (R) 21 ', green (G) 22 ', blue (B) 23 ' three sub-pixels being parallel to each other in a pixel unit 2 '.In order to process this
Pixel arrangements, corresponding metal mask plate 3 ' is as shown in Figure 1B.
This metal mask plate 3 is to be correspondingly arranged slot in the position of the sub-pixel 21 ' of a certain color it can be seen from Figure 1B
Shape opening 31 ', since the sub-pixel 21 ' of same color in the arrangement mode of Figure 1A is upper and lower contraposition setting, metal is covered
The slit opening 31 ' of template 3 ' must also align setting, this takes the metal between two longitudinally adjacent slit openings 31 '
Bridge (bridge) 32 ' has the risk of broken string.Also or, because metal put up a bridge (bridge) it is tiny, can not be in level when throwing the net
Direction force is excessive, or causes metal bridging (bridge) broken string because force is excessive.Meanwhile the slit opening of mask plate 31 '
31 ' need to correspond to scheduled location of pixels, according to a kind of this existing pixel arrangement mode, 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 (band-like) mode
Fig. 2A shows the pixel arrangements corresponding to band-like Opening mask plate traditional used in OLED screen curtain, such as
Shown in Fig. 2A, it is parallel to each other in a pixel unit 2 " of substrate 1 " including red (R) 21 ", green (G) 22 ", 23 " three, indigo plant (B)
Sub-pixel.In order to form the pixel arrangements, corresponding metal mask plate 3 ' is as shown in Figure 2 B.
This metal mask plate 3 " is correspondingly arranged in the position of the sub-pixel 21 " of a certain color it can be seen from Fig. 2 B
Band shaped opening 31 ", band shaped opening 31 " is elongated, avoids the broken string wind of the metal bridging 32 ' of the mask of slit opening 31 '
Danger.However, need to maintain its linearity and flatness with shaped opening 31 ", it is relatively difficult to achieve on fine metal mask.
In conclusion existing metal mask plate has the shortcomings that as above, especially needing to propose high-resolution demand
Under, existing pixel arrangement mode and metal mask plate are difficult to realize guarantee the demand of vapor deposition quality under high-resolution.Therefore,
Need to propose a kind of dot structure with new arrangement and corresponding metal mask plate and OLED display screen, it is existing to solve
The problem of with the presence of technology.
