The invention discloses a
liquid crystal panel which comprises a pixel area and a test short-circuiting bar area arranged at the periphery of the pixel area, wherein the short-circuiting bar area is provided with a plurality of first switch circuits, a plurality of scanning
signal test points, a public
electrode test point, a plurality of first unidirectional circuits or second switch circuits, and a plurality of
data signal test points; scanning
signal lines are connected with the scanning
signal test points by the first switch circuits;
data signal lines are connected with the
data signal test points by the first unidirectional circuits or second switch circuits; and a public
electrode is connected with a public
electrode test point. The invention also discloses a method for clarifying reasons resulting in poor screen images of a
liquid crystal module. Through the way, by using the
liquid crystal panel disclosed by the invention, an effect of saving
cutting equipment and a process of
cutting a test lead of the short-circuiting bar area in the manufacturing process of
assembly can be achieved, so that in the subsequent production stages after the manufacturing process of
assembly, the test lead of the short-circuiting bar area can continue to be used for carrying out screen
image detection, thereby improving the test accuracy of screen images.
