Problems solved by technology

Existing metal masks have a single purpose, making it difficult to achieve product diversification
Each product needs to produce a large number of corresponding Masks, which is expensive and time-consuming; when the product is updated, the original Mask cannot be recycled, resulting in secondary waste

Embodiment approach 1

[0028] refer to figure 1 , image 3 and Figure 4 , an OLED evaporation mask, including a metal frame 10 , four horizontal metal sheets 402 and three vertical metal sheets 401 arranged on the metal frame through a positioning device 20 and a fixing device 30 .

[0029] In this embodiment, the metal frame 10 is a rectangular frame, and a rectangular groove 101 with a width of about 10 mm and a depth of about 5 mm is provided in the frame of the two length directions, and a width of about 101 is arranged in the frame of the two width direction. 10 mm rectangular groove 104 with a depth of about 5.1 mm. The outer edges of the rectangular groove 101 and the rectangular groove 104 are provided with main scale marks with an accuracy of 1 mm. Two parallel first transverse guide rails 102 are arranged in the rectangular groove 101 , and two parallel longitudinal first guide rails 103 are arranged in the rectangular groove 104 . The first guide rails 102, 103 are T-shaped, the bott...

Embodiment approach 2

[0038] refer to figure 2 , Embodiment 2 has basically the same structure as Embodiment 1, the only difference is that two horizontal metal sheets 402 and four vertical metal sheets 401 are provided on the metal frame, and two horizontal metal sheets 402 and four vertical metal sheets 401 forms nine mask units.

[0039] Embodiment 2 is a modification made on the basis of Embodiment 1. It is only necessary to adjust the position of the positioning device in Embodiment 1 and increase or decrease the number of horizontal and vertical metal sheets to obtain the design of Embodiment 2.

[0040] In other embodiments, it can also be deformed into various product shapes as required.

Abstract

The invention discloses an OLED evaporation mask plate. A pair of longitudinal grooves and a pair of transverse grooves are formed in two opposite side frames of a metal frame. First guide rails are arranged in the grooves, and main scale marks are arranged on the edges of the grooves. Sheet metal is arranged in the longitudinal grooves and the transverse grooves through positioning devices, and can slide along the first guide rails. Auxiliary scale marks and fixing devices are arranged on the positioning devices, the sheet metal is precisely positioned through cooperation of the main scale marks and the auxiliary scale marks, and the tightness of the sheet metal can be adjusted through the fixing devices. The transverse and longitudinal positions of the sheet metal in the metal frame areadjustable, the evaporation mask plate with any rectangular pattern can be formed, evaporation process of multiple specifications can be completed through one evaporation mask plate, and diversified production of products is achieved.

Description

technical field [0001] The invention relates to the technical field of OLED production, in particular to an OLED evaporation mask. Background technique [0002] Organic Light Emitting Diode (OLED, OrganicLightEmittingDiode) has lower power consumption compared with traditional liquid crystal displays, and also has high brightness, high response speed and wide color gamut, and has become the current mainstream device in the display field. [0003] The structure of an OLED device generally includes a substrate, on which two thin-film electrodes are fabricated, and a multi-layer organic thin film, referred to as a light-emitting layer, is fabricated between the two electrodes, and the device will emit light when electricity is applied between the two electrodes. The most commonly used substrate is made of transparent glass. After the device is powered on, the light emitted by the device passes through the glass substrate and enters the air for display or lighting. These are cal...
