Abstract
A display panel includes a plurality of touch blocks matrix-arranged and corresponding to each of two or more adjacent pixel areas of the plurality of pixel areas, and first, second, third and fourth test signal lines through which first, second, third and fourth test signals are supplied by an auto probing unit. Accordingly, not only a defect in an image output function, but also a defect in a touch sensing function can be inspected prior to a modularization process by using the first, second, third and fourth test signals.
Claims7
A display panel comprising:
- a plurality of pixel areas defined in a display area and matrix-arranged, the plurality of pixel areas corresponding to a plurality of sub-pixels;
- a plurality of touch blocks matrix-arranged, each touch block corresponding to two or more adjacent pixel areas of the plurality of pixel areas;
- a first test signal line conducting a first test signal received from an auto probing unit;
- a second test signal line conducting a second test signal received from the auto probing unit;
- a third test signal line conducting a third test signal received from the auto probing unit;
- a fourth test signal line conducting a fourth test signal received from the auto probing unit;
- and
- a plurality of routing lines, each of the routing lines connected between one of the first, second, third, and fourth test signal lines and one of the plurality of touch blocks,
- wherein four touch blocks of the plurality of touch blocks adjacent along a first direction are each connected to a different one of the first, second, third, and fourth test signal lines, and
- wherein four touch blocks of the plurality of touch blocks adjacent along a second direction perpendicular to the first direction are each connected to a different one of the first, second, third, and fourth test signal lines.
