Description

Mask module

The present invention relates to a mask module, and more particularly to a mask module that can shield an area that does not need to be irradiated with ultraviolet light in an ultraviolet curing process.

The liquid crystal display mainly comprises a color filter (CF) substrate and a thin film transistor array (TFT array) substrate. After the two substrates are separately fabricated, the manufacturer injects liquid crystal between the two substrates, and bonds the color filter substrate and the thin film transistor array substrate with an adhesive layer. Such an adhesive layer is typically an ultraviolet curable adhesive that cures under ultraviolet light. Therefore, the manufacturer can irradiate the adhesive layer with ultraviolet light to cure it, and fix the color filter substrate and the thin film transistor array substrate.

Since the adhesive layer is only located in a partial region between the color filter substrate and the thin film transistor array substrate (for example, a region that does not overlap with the thin film transistor), only the portion of the region needs to be irradiated with ultraviolet light. In order to prevent ultraviolet light from being irradiated to other areas between the color filter substrate and the thin film transistor array substrate, the manufacturer places a mask on the ultraviolet light source and the substrate. Between, to mask areas that do not need to be exposed to ultraviolet light.

To support the mask, the manufacturer typically places a quartz glass with a plurality of holes above the mask. These holes are connected to a vacuum source. The holes are evacuated by a vacuum source, and the mask can be adsorbed on the quartz glass. However, the above-mentioned vacuum source and quartz glass are expensive to manufacture, which is bound to increase the manufacturing cost.

In view of the above, the present invention provides a mask module that can reduce the manufacturing cost without using a vacuum source and quartz glass to adsorb the mask.

According to an embodiment of the present invention, a mask module includes a frame, at least one first rope fixing device, at least one second rope fixing device, at least one rope, and a mask. The frame has a first frame strip and a second frame strip. The second frame strip is separated from the first frame strip. The first rope fixing device is disposed on the first frame strip. The second rope fixing device is disposed on the second frame strip. The opposite ends of the rope are respectively fixed to the first rope fixing device and the second rope fixing device. The mask is located between the first frame strip and the second frame strip, and the mask is supported by the rope. The mask has at least one light transmissive region and at least one light shielding region adjacent to the light transmissive region.

According to the above embodiment, the mask can be supported by the ropes spanning the first frame and the second frame without being adsorbed by the vacuum source and the quartz glass having the holes, so that the manufacturing cost can be greatly reduced.

The above description is only used to explain the problems to be solved by the present invention, the technical means for solving the problems, the effects thereof, and the like, and the specifics of the present invention.
