The application proposes a display substrate for using in a display screen.
In the embodiment of the present application, as shown in
The substrate body 10 has a display area 11 and a non-display area 12;
The driving signal line 20, disposed in the non-display area 12;
The controlling signal line 30 is disposed in the non-display area 12, and the driving signal line 20 is disposed at an intersecting with the controlling signal line 30 to form an intersecting area, and the driving signal line 20 is provided with a first repair in the intersecting area. The hole 21 is formed to divide the intersecting of the driving signal line 20 into the first intersecting segment 22 and the second intersecting segment 23.
In this embodiment, the display screen adopts the GOA technology to realize the driving display mode of the progressive scanning, and the driving technology has the advantages of reducing the production cost and realizing the narrow frame design of the panel. In the process of preparing the display screen by using the GOA technology, a scan driving unit and a data driving unit are disposed in the non-display area 12 of the display screen, one end of the driving signal line 20 is electrically connected to the scanning driving unit, and the other end is electrically connected to the data driving unit; One end of the controlling signal line 30 is electrically connected to the data driving unit, and the body is electrically connected to the driving signal line 20. It should be noted that the number of the driving signal line 20 and the controlling signal line 30 is plural, the plurality of driving signal lines 20 are disposed to intersect with the plurality of controlling signal lines 30, and one driving signal line 20 is only electrically connected to one controlling signal line 30, that is, before each of the driving signal lines 20 is electrically connected to the corresponding controlling signal line 30 at its end, the driving signal line 20 is crossed and insulated from the other controlling signal lines 30 to realize the stable transmission of data signals between scanning driving unit and the data driving unit. The driving signal line 20 and the controlling signal line 30 are performed in the non-display area 12 of the substrate body 10 in the preparation process of the display substrate.
The position where the driving signal line 20 intersects with the controlling signal line 30, that is, the position where the projection overlaps forms an intersecting region, and the first repairing hole 21 is opened at the intersecting region of the driving signal line 20, and dividing the intersection area into the first intersecting segment 22 and the second intersecting segment 23 along the width direction of the driving signal line 20, the inner edges of the first intersecting segment 22 and the second intersecting segment 23 are the edge of the first repairing hole 21, and the shape of the first repairing hole 21 may be a circle, a rectangle, a waist, or the like.
When the conductive foreign matter falls into the intersecting of the driving signal line 20, causing the driving signal line 20 and the controlling signal line 30 to be electrically short-circuited at the position, the display effect of the display screen may be abnormal, and the position of the short circuit may be determined by the detecting device. If the conductive foreign matter falls on the first intersecting segment 22, the portions on both sides of the conductive foreign matter on the first intersecting segment 22 may be cut, such as by a laser cutting process, to disconnect the conductive foreign matter from the overall circuit, thereby realizing the short circuit problem repair of the position realizing, at which time the drive signal line 20 remains electrically connected through the second cross segment 23.
The present application shows that the substrate has a first repairing hole 21 formed in the intersecting of the driving signal line 20, and the first repairing hole 21 divides the intersecting area of the driving signal line 20 into a first intersecting segment 22 and a second intersecting segment 23 in the width direction of the driving signal line 20, thereby reducing the intersecting area of the driving signal line 20 and the controlling signal line 30, thereby reducing the risk that foreign matter falling in the intersecting area that causes the controlling signal line 30 and the driving signal line 20 to be short-circuited, thereby reducing the defect rate of the display screen. If the foreign matter falls on the first intersecting segment 22 or the second intersecting segment 23, it is only necessary to cut the portions on both sides of the foreign object on the first intersecting segment 22 or the second intersecting segment 23, to drive the foreign matter part to be disconnected from the driving signal line 20. At this time, the driving signal line 20 can be electrically connected through the uncut cross segment, thereby effectively repairing the short-circuited position of the controlling signal line 30 and the driving signal line 20. The defect rate of the display substrate is lowered, thereby reducing the production cost of the entire display screen.
