Abstract

The utility model discloses a mask group for organic electroluminescent display evaporation. The mask group comprises a first edge mask, a second edge mask and a plurality of center masks. The plurality of center masks are arranged between the first edge mask and the second edge mask. A whole mask is divided into the edge mask and the plurality of center masks, and partial replacement is performed conveniently on purpose. The mask group for the organic electroluminescent display evaporation is simple in structure, does not increase manufacturing difficulty, can effectively reduce consumption of the mask, effectively controls expenditure of the mask, and greatly reduces production cost.

Description

A kind of display of organic electroluminescence evaporation mask group

[technical field]

The utility model relates to the display of organic electroluminescence preparation field, particularly a kind of display of organic electroluminescence evaporation mask group.

[background technology]

Display of organic electroluminescence OLED is emerging a kind of flat-panel monitor, because it has active illuminating, contrast gradient is high, the energy slimming, the plurality of advantages such as fast response time, be acknowledged as the third generation indicating meter that substitutes LCD, its principle of luminosity is some layers of organic materials of cord wood evaporation (comprising luminous organic material) between two electrodes, and direct current makes it luminous on logical between two electrodes.

In display of organic electroluminescence is made, in order to obtain effective pixel cell, need to use the evaporation mask, this mask thickness is at 0.030～0.100mm, multiselect INVER material, the technique manufacture difficulty is larger, and yield is lower, and only have minority producer to produce, therefore expensive.

In whole display of organic electroluminescence manufacturing cost, the mask expense accounts for more than 10% of manufacturing cost, is the principal element that directly affects the device manufacturing cost.

The OLED evaporation all is to adopt whole mask with mask at present, in case certain has problem all to need whole replacings, not only wastes time but also increase cost.

[utility model content]

The purpose of this utility model provides a kind of display of organic electroluminescence evaporation mask group, to solve the problems of the technologies described above.

For reaching above purpose, the utility model adopts following technical scheme:

A kind of display of organic electroluminescence evaporation mask group comprises first side section mask, Second Edge section mask and some centres mask; Described some centres mask is arranged between first side section mask and the Second Edge section mask.

The utility model further improves and is: the shape of described some centres mask is identical.

The utility model further improves and is: the width of centre mask is 30～200mm.

The utility model further improves and is: first side section mask is identical with the width of Second Edge section mask, is 50～200mm.

The utility model further improves and is: described first side section mask, Second Edge section mask are identical with the thickness of some centres mask, are 0.020～0.100mm.

The utility model further improves and is: the number sum of described first side section mask, Second Edge section mask and some centres mask is odd number.

Compared with prior art, the utlity model has following advantage: a kind of display of organic electroluminescence evaporation mask group of the utility model, whole mask is divided into limit section mask and some centres mask, be convenient to have purpose to carry out local replacing; The utility model is simple in structure, and manufacture difficulty does not increase, and can effectively reduce the mask consumption, thereby effectively control the expenditure of mask expense, greatly reduces production costs.

[description of drawings]

Fig. 1 is evaporation with conventional mask schematic diagram;

Fig. 2 mask is used view;

The schematic diagram of Fig. 3 the utility model Splittable mask group.

[embodiment]

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.

See also Figure 1 and Figure 2, existing conventional mask 1 is whole integral structure; The effect of whole metal mask version 1 is the mask of evaporating organic materials 2, makes organic materials 2 figure as required be attached on the substrate 3.

See also shown in Figure 3, a kind of display of organic electroluminescence evaporation mask group of the utility model adopts the mode of cutting apart, and whole the mask 1 that present industry is generally adopted is divided into strip-type, in order to only change this band when there is problem in the somewhere, not only handled easily but also reduce manufacturing cost.A kind of display of organic electroluminescence evaporation of the utility model comprises following part with the mask group:

1) Splittable centre mask 4;

2) Splittable limit section mask 5;

The material of centre mask 4 and limit section mask 5 is SUS or INVER.

The width of centre mask 4 is 30～200mm; The width of limit section mask 5 is 50～200mm.

The thickness of centre mask 4 and limit section mask 5 is 0.020～0.100mm.

Take 730 * 460 substrates as example, its number general control of using centre mask 4 and limit section mask 5 is at 5～10.

The number of centre mask 4 and limit section mask 5 adopts odd number as far as possible, is conducive to like this use.

The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
