Description
Technical field
The present invention relates to electronic printing field, relate in particular to a kind of assemble method of mask assembly.
Background technology
Compare with existing LCD technology, utilizing the made indicating meter of organic light emitting diode (OLED) technology not only to have can true color, the reaction times is fast, high brightness (100 ~ 14,000cd/m
2), the above visual angle of high luminous efficiency (16 ~ 38lm/W), 170 degree, LCD ghost as none, can be made into large size and flexibility panel, can be in the scopes of-30 degree ~ 80 degree Celsius the advantage such as operation, and processing procedure simply, integral thickness also can be contracted to below 1mm, cost more only has 30 ~ 40% of TFT-LCD.Therefore, utilize the made indicating meter of OLED technology firmly getting society's welcome.
At present, the made indicating meter of OLED technology has reached volume production technology in small size, and comparatively ripe.But for by manufacture a plurality of OLED indicating meters to realize the raising of output simultaneously, or produce large-sized OLED indicating meter, just need to increase the size of the large substrate of tradition, just must increase the size for the mask assembly of evaporation organic materials accordingly.
Shown in Figure 14, be that tradition is for the structural representation of the mask assembly of evaporation organic materials, it comprises housing 11 and is fixed on the mask portion 12 on housing 11 by solder joint 120, mask portion 12 is welded on housing 11 by applying at two ends after pulling force is tightened, and discharges pulling force after welding.During mask assembly horizontal positioned, because mask portion 12 bounces back in the other direction and causes housing 11 Shang Xia (in Figure 14 up and down orientation) support section to occur the phenomenon of indent shown in figure along original pulling force, thereby make mask portion 12 occur sagging (particularly mask portion 12 region intermediates), the consequence so causing is that pattern position precision, the size that evaporation obtains relatively all can have certain deviation, thereby affects quality and the yield of product.
Chinese Patent Application No. is 2010101136655 to disclose a kind of mask assembly and for using the depositing device of the flat-panel monitor of this mask assembly, its primary structure is: on the housing of mask assembly, be provided with the support stick of the open area forming across housing, thereby reduce the sag of chain of mask portion.The Chinese patent patent No. provides a kind of mask for the manufacture of large size display panel for 01138161.2, and it comprises: have the main frame in a plurality of holes, in the hole that is assemblied in main frame according to the size that will manufacture and pattern from mask.With upper type, have certain effect realizing in OLED indicating meter volume production, but there is certain limitation making on large size display screen.
Summary of the invention
In view of this, need to overcome at least one in above-mentioned defect of the prior art.The invention provides a kind of assemble method of mask assembly.
