The invention discloses a photomask, which comprises a display area mask and a distributing area mask arranged around the display area mask, wherein the distributing area mask is completely opaque, and the display area mask comprises a plurality of pixel regions and spacer regions between two adjacent pixel areas. The spacer regions are completely opaque, and each of the pixel regions has an exposure pattern that is intermittent. The invention also discloses a method for recycling defective products of LCD panels through the above-mentioned photomask, by which the defective products in the production process of the UV2A production line can be reused without increasing the UV2A breaking device. The method has the advantages of not only recycling the non-defective product part among defective products, but also reducing the waste of production capacity and raw materials caused by the flowing of the defective products into next production stage, thus reducing the scrapping of the products, saving the production cost and improving the production efficiency.
Description
technical field [0001] The invention relates to the field of liquid crystal display technology, in particular to a mask plate used in the manufacture of liquid crystal panels and a method for reusing defective liquid crystal panel products using the mask plate. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD for short) is a kind of liquid crystal display. It has the characteristics of low energy consumption, high brightness, high contrast, high response speed, and environmental protection. It is widely used in TV, on flat panel displays and projectors. With technological innovation and market demand, the demand for large-size panels is increasing year by year, and more and more panel makers have begun to increase the proportion of production capacity of large-size panels. [0003] In the process of making LCD panels, alignment technology is a relatively key technology. In the current production stage, there are two main alignment technolog...
