Embodiment 1

[0033] This embodiment provides a mask stretching device, such as figure 1 As shown, a clamp unit 1 is included, and the clamp unit 1 includes:

[0034] Two pairs of first clamps 11 are respectively used to clamp and stretch the four corners of the mask plate 2;

[0035] A plurality of second clamps 12 are provided between adjacent first clamps 11 for clamping and stretching the edge of the mask plate 2 .

[0036] The mask stretching device of this embodiment adopts two pairs of first clamps 11 to clamp and stretch the four corners of the mask 2 respectively, and a plurality of second clamps arranged between adjacent first clamps 11 12 clamps and stretches the edge of the mask 2, so that multiple second clamps 12 realize precise adjustment and control of the mask 2, stretch evenly, improve the ability to stretch the net, and make the mask 2 difficult to produce Wrinkle, reduce color mixing, improve display yield. Specifically, the stretching of the first jig 11 and the seco...

Embodiment 2

[0038] This embodiment provides a mask stretching device, such as figure 2 As shown, it includes a fixture unit 1 , a measurement unit 3 and an adjustment unit 4 .

[0039] Specifically, the clamp unit 1 includes: two pairs of first clamps 11, respectively used to clamp and stretch the four corners of the mask plate 2; a plurality of second clamps are arranged between adjacent first clamps 11. The clamp 12 is used to clamp and stretch the edge of the mask plate 2, wherein the contact area between the first clamp 11 and the mask plate 2 is larger than that between the second clamp 12 and the mask plate 2 Contact area.

[0040] That is, if image 3 As shown in the part framed by a dotted line, the first clamps 11 clamp the four corners of the mask 2 , and the multiple second clamps 12 in the middle clamp the four edges of the mask 2 . The contact area between the second fixture 12 and the mask 2 is smaller than that of the first fixture 11, that is, the contact area between ...

Embodiment 3

[0047] This embodiment provides a mask stretching device, such as Figure 4 As shown, the stretching device is provided with a loading hole 5 for fixing the mask plate 2 , and the loading hole 5 is arranged above the mask plate 2 .

[0048] That is to say, there is a loading hole 5 on the stretching device, which can be used for alignment, that is, when the loading hole 5 coincides with the predetermined position of the mask plate 2, it means that the mask plate 2 has been flattened. If the loading hole 5 does not coincide with the predetermined position of the mask 2 , it means that there are wrinkles on the mask 2 .

[0049] Preferably, the mask plate 2 between the adjacent second jigs has an opening, and the opening of the second jig far away from the loading hole is smaller than the opening of the second jig close to the loading hole 5 .

[0050] That is to say, the root areas of the openings of the second clamp 12 form an arc with each other. Such as Figure 4 As shown b...

Abstract

The invention provides a netting device and a netting method for a mask template, and belongs to the technical field of display, and the problem that red, green and blue devices are mixed in color due to the fact a current mask plate generates folding as a result of uneven tension can be solved. The netting device for the mask template adopts two pairs of first clamps to separately clamp and stretch four corners of the mask template; the edge of the mask template is clamped and stretched by a plurality of second clamps which are arranged between adjacent first clamps, so that the plurality of the second clamps realize precise regulating and control, and uniform stretching of the mask template, and therefore, netting capacity is improved, the mask template is not liable to generate folding, color mixing is reduced and a display yield is increased. The netting device for the mask template provided by the invention is suitable for stretching various mask templates, and is especially suitable for manufacturing the mask template of a small-dimension display panel.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a netting device and a netting method for a mask plate. Background technique [0002] Organic Light Emitting Diode (OLED) display devices have the advantages of thinness, low power consumption, high contrast, high color gamut, flexible display, etc., and are the development trend of the next generation of displays. [0003] OLED display devices include passive organic electroluminescent diodes (PMOLED) and active matrix organic light emitting diodes (AMOLED). The implementation of AMOLED includes: low temperature polysilicon (LTPS) backplane + fine metal mask (FMM Mask ) method, and the method of oxide (Oxide) backplane + white OLED backlight (WOLED) + color film. The former is mainly suitable for small-sized panels, mostly used in mobile display devices and mobile phones; the latter is mainly suitable for large-sized panels, mostly used in Monitors and TVs. [000...
