Description
Technical field
A kind of white light OLED that relates to of the present invention is done in the technique in order to make organic deposit and the encapsulation mask frame of white light OLED panel with tv mechanism, its manufacture method and making apparatus, more particularly relate to a kind of in order to maximize with the white light OLED that active matrix organic light-emitting diode (AMOLED) panel (AMOLED) gets most of the attention more than the 4th generation, and utilize the mask frame of a plurality of metal bar mask manufactures, with its manufacture method and making apparatus.
Background technology
The response speed of OLED (Organic Light Emitting Diode) is faster than Thin Film Transistor-LCD (TF T LCD).In addition, because self can be luminous, need not backlight, so thickness and weight can reduce 1/3rd, be time from generation to generation display with wide visual angle and low power consumption structure.
Such OLED is divided into AM mode (initiatively) and PM mode (passive).Passive matrix organic light emitting diode (AMOLED) panel (PMOLED) is than active matrix organic light-emitting diode (AMOLED) panel (AMOLED), low production cost, but be restricted in power consumption, life-span, resolution.AMOLED uses TFT and electric capacity in each pixel, all very outstanding on power consumption, life-span, resolution side, therefore ignored the high shortcoming of production cost that causes because TFT makes, in every field, be subject at present developing widely and in rapid succession volume production trial.The great advantage of AMOLED is its competitiveness on image quality.Than maximum contention adversary's LCD, its recall factor of checking colors has exceeded 30%, contrast even outstanding 20 times more than.The image image retention effects of LCD disadvantage also has no way of looking in AMOLED.This be because, in contrast to LCD, backlight be with indirect light source by liquid crystal, chromatic filter etc., for the picture disply of complexity, AMOLED is by the self-colored picture of the luminous direct reproduction of organic substance self.In addition, OLED is than LCD, and its structure is very simple, and is therefore also highly beneficial in the parts side.
But when checking OLED material original cost, drive circuit, drive IC price, the devaluation ratio of OLED arrives greatly unexpectedly, has accounted for half of total cost.This is because OLED universalness between the consumer not yet causes being difficult to play the effect that reduces production costs by large-scale production.
Because this realistic problem, white light OLED technology become recently emerging Display Technique.White light OLED is carried out simple declaration is exactly, the technology that the advantage of the advantage of LCD panel and AMOLED panel is merged.
That is, place white light OLED and the TFT with handoff functionality at the R/G/B of display color primary colors filter, the white light OLED that self is luminous switches to the Display Technique that TFT shows R/G/B primary colors color filter.
If this white light OLED panel can be realized maximizing, can provide other volume production yield of LCD level the popular high-quality display floater suitable with AMOLED.
But present truth is, also do not provide can produce in a large number LCD that present masses popularize or PDP level other more than 40 inches or the 8th generation above white light OLED panel technology, therefore popularizing high-quality display floater is remote truth.
Really be to possess large-sized coil to realize individual mode, but be difficult to utilize the mask of individual formation to realize that the reason that maximizes is, the size that the raw-material coil of mask is supplied with, not the size dimension production to maximize required.That is, because profitability problem, coil production merchant can not remove to produce the coil that white light OLED shows the required size of manufacturer.
In addition, for a large amount of white light OLED panels of making more than the 4th generation, if have fine, the white light OLED that can also deposit white light OLED is simultaneously laid the groundwork with the manufacturing technology of mask frame, just can overcome the yield problem and realize volume production, but the manufacturing technology of most mask frame or equipment all are for the purposes of LCD or the making of AMOLED panel, therefore are difficult to directly be applied as the white light OLED mask frame.
Concrete reason is that the AMOLED that formed the LCD of maximization in the past or developing the maximization technology is with in the manufacture method or making apparatus of mask frame, such as FMM Type OLED, for R/G/B is precipitated with organic substance, utilization has formed the metal mask (Fine Metal MASK) of corresponding intensive groove in each pixel, utilize open mask that Metal is deposited and encapsulates.But white light OLED is different with it, for corresponding R/G/B color, has used the filter that uses in the LCD manufacture craft, has therefore all utilized open mask in White organic deposition and metal deposition and packaging technology.Therefore, do not need the applied metal mask, multiaspect is got when making in individual inside that is produced on of open mask, can be because the restricted and very difficult application of Mask Coil Size.
In addition, as shown in figure 11, get the mode in the past that multiaspect is made in individual inside, be difficult to make mask in the situation that not tenesmus is kept tension force, critically settled, therefore, be difficult to produce large-area white light OLED mask frame.
That is, if mask does not have tension force, meeting cause central authorities' appearance of mask sagging because the position is accurate not, and is influential to shade (Shadow) and deposition position, so the white light OLED panel of fine can't be provided, and the problem that yield reduces occurs.
