Kind Code:
A1
Abstract:
A display panel and a display device, relating to the technical field of display. The display panel comprises a display area (A) and a frame area (B) located at the periphery of the display area (A). The display area (A) comprises a plurality of sub-pixels (21) and a plurality of data lines (22) connected to the sub-pixels (21). The frame area (B) comprises a test area (B1) and a binding area (B2). The test area (B1) comprises a plurality of test units (31) arranged periodically in a first direction, each test unit (31) comprises at least one switch transistor (32), a first electrode of the switch transistor (32) is connected to a test signal lead (33), and a second electrode of the switch transistor is connected to the data line (22). The binding area (B2) comprises a plurality of binding units (34) arranged periodically in the first direction, each binding unit (34) comprises at least one binding pad (35), and the binding pad (35) is connected to the data line (22). In the first direction, a ratio of the number of the switch transistors (32) comprised in one arrangement period of the test units (31) to the number of the binding pads (35) comprised in one arrangement period of the binding units (34) is greater than 0 and less than 2.
