Description
Technical field
The present invention relates to a kind of mask assembling method, particularly relate to the assembly method of the used mask of a kind of organic light emitting display.
Background technology
Organic light emitting display (Organic Light Emitting Display, be called for short OLED) not only possess the light and handy thin characteristics of the few and LCD display of brightness height, the consumes energy of CRT monitor, also have the environmental limit of not being subjected to, need not the outstanding advantage of backlight, even if also can easily see pattern and character clearly in the sun, and has the function of convolution.The OLED display screen can be done lighter and thinnerly, and visible angle is bigger, and can significantly save electric energy.The composition of OLED comprises the glass substrate of 1 agreement that contracts a film or TV play to an actor or actress 1.3mm, less than high purity metal material and the ITO electro-conductive glass of 0.3mm, gross thickness is less than 2mm.The manufacturing key link of OLED is, luminous organic material is applied to the ITO surface, and its coating quality has directly determined the quality of OLED.
And the mask of control luminous organic material coating quality is except that the parameter request of itself, also must be very smooth, closely contact with the ITO electro-conductive glass.Like this, in assembling process, be contained on the mask housing with extremely smooth state group with regard to requiring mask.
Summary of the invention
Purpose of the present invention be exactly for provide a kind of can realize with mask smooth be assembled into mask assembling method on the housing.
For achieving the above object, the present invention has adopted following technical scheme:
The invention discloses a kind of mask assembling method of organic light emitting display, described method in turn includes the following steps:
A. silk screen is drawn back on net puller;
B. the silk screen that draws back and is used the bonding and curing of glue as the metal frame of aid at the frame place of metal frame;
C. mask is tiled in metal frame with on the interior silk screen, and the bonding and curing with glue with mask outward flange and silk screen;
D. the bonding location that cuts off mask and silk screen is with interior silk screen;
E. with the mask housing with partly carry out bonding at the bonding location of mask and silk screen with interior mask.
The mask that described mask is used for the vaporization coating of organic light-emitting display luminous organic material.
Among the described step a, when silk screen was drawn back on net puller, wire drawing net tension force was 12N/CM, and inhomogeneities is ± 2N/CM.
Before described step a, also comprise the step of eliminating silk screen stress.
Further, the step of described elimination silk screen stress is meant that specifically it is 35N/CM that silk screen is pulled to tension force at net puller, keeps unclamping after 15 minutes, and again silk screen being pulled to tension force is 35N/CM, and keeps unclamping after 15 minutes.
Described silk screen is a polyester webs.
Further, described polyester webs is 80～100 purpose polyester webs.
Described glue is epoxide-resin glue.
Among the described step c, mask is tiled on the silk screen, method is that mask is placed between two parties, and the mask four limits inward flange distance corresponding with metal outer frame equates, fix with gummed paper, the bonding and curing with glue with mask outward flange and silk screen again forms the abutting edge and centers on the close-shaped of mask periphery again.
Behind the described step e, further comprise step, the peripheral auxiliary material with mask housing and mask after bonding cut off, and make finished product, and described peripheral auxiliary material comprise the unnecessary mask and the silk screen of part beyond the mask housing.
Because adopted above scheme, the beneficial effect that the present invention is possessed is:
Assembly method of the present invention is used the tension force of silk screen dexterously, makes mask can keep very high evenness in being assembled into the process of housing, thereby the planarization that has guaranteed the finished product that assembles can satisfy the production needs.
Embodiment
The present invention is described in further detail below by concrete execution mode.
The assembly method of the mask that a kind of vaporization coating of organic light-emitting display is used, in the method, at first with on the silk screen to net puller, and eliminate silk screen stress.Eliminating the method that silk screen stress adopted is: to be pulled to tension force be 35N/CM and kept 15 minutes at net puller silk screen, unclamps then; Then again silk screen being pulled to tension force is the same maintenance of 35N/CM 15 minutes, unclamps then.
Again go up on the net puller having eliminated stress silk screen afterwards, keeping wire drawing net tension force is 12N/CM, and inhomogeneities is ± 2N/CM.Then a metal frame and the silk screen that draws back are used the bonding and curing of glue at the frame place of this metal frame, in the present embodiment, this metal frame is the aluminium frame, and the wide about 4cm of frame.This aluminium frame is to use as aid in assembling process, and the size of this aluminium frame must be greater than the size of mask used in the assembling process, and in this execution mode, used aluminium frame is identical with the mask shape, but size is greater than the rectangle of mask.Aluminium frame and silk screen bonding and solidify after, for the convenience of operating, can prescind the silk screen between aluminium frame and the net puller, take off the aluminium frame that is covering silk screen.
Then mask (in the assembling process used mask must greater than the size of mask housing) is tiled on the silk screen of aluminium frame inside between two parties, after blended rubber paper is fixing, be bonded together with the outward flange and the silk screen of glue with mask, bonding part is along about about the 1 centimetre zone of mask outward flange.After bonding, the abutting edge forms enclose Monday close-shaped outside mask, and this close-shaped everywhere is all equal to the distance of aluminium frame inside casing.Bonding and solidify after, slice off bonding region with interior silk screen, form the state that is connected by silk screen between mask and the aluminium frame, and the tension force of silk screen makes mask also keep certain force of strain, forms smooth state.
Then again mask housing and mask are carried out bondingly, again mask housing unnecessary mask is in addition cut off afterwards, thereby the assembling process of finishing makes finished product.
More than used silk screen be a kind of 92 purpose polyester webs, used glue is epoxide-resin glue.
