Abstract

The invention provides a mother substrate used for detecting winding of an array and a detecting method thereof. The mother substrate consists of a liquid crystal panel array and a testing area, wherein the liquid crystal panel array comprises m rows and n columns of liquid crystal panels, an array winding is arranged between grid electrode driving areas and source electrode driving areas in the liquid crystal panels, and the testing area further comprises a testing pad group and a testing line group which are electrically connected with each other. In addition, the testing line group penetrates through the area at which the liquid crystal panel array and the testing pad area are positioned. The array winding and the testing line group are electrically connected by virtue of an outgoing line group so as to detect the array winding in the liquid crystal panels, one end of the outgoing line group is electrically connected to the array winding of the liquid crystal panel, and the other end of the outgoing line group is electrically connected to the testing line group. Furthermore, the detection method is used for detecting the situation of the array winding by means of the outgoing line group through a detection system with strong observability.

Description

【Technical field】

[0001] The invention relates to a mother substrate and a method for detecting the Wire On Array (WOA) in a liquid crystal panel on the mother substrate, in particular to a test wire group (shorting) that leads the array winding group in the liquid crystal panel to the surrounding arrangement. bar) and a method for detecting array winding groups using a highly observable detection system. 【Background technique】

[0002] In an environment where liquid crystal display (Liquid Crystal Display, LCD) technology is becoming more and more mature, in order to enhance their competitiveness in this field, LCD panel manufacturers around the world must undoubtedly ensure The most basic panel yield.

[0003] In the manufacturing process of liquid crystal panels, a plurality of liquid crystal panels (Unit Cells) are generally produced on a large glass substrate, also known as a mother substrate, and the liquid crystal panels are arranged in an array. Afterwards, it is d...
