Benefits of technology
[0034]In an embodiment, an extending direction of the first side and the second side is consistent with the extending direction of the gate line, and the display mode of the display panel is in the normally black mode. The method further includes inputting a voltage for displaying a white state to the data line and inputting a turn-on voltage to the gate line, determining the light transmitting section being unlighted as an abnormality mark, and determining the data line corresponding to the abnormality mark as an open circuit.
Problems solved by technology
Defective lines may appear in the display device.
Thus, the conventional method takes a lot of time and labor, and cannot quickly confirm whether the abnormal dots are located inside the display region or not.

Abstract
The present disclosure relates to a color film substrate, a display panel and a method for detecting a display panel. The CF substrate includes a display region and a peripheral region corresponding to a dummy pixel region around the display region. A black matrix of the color filter substrate includes a light transmitting section in a portion of the peripheral region corresponding to a dummy pixel unit. The light transmitting section includes a first set of light transmitting sections and a second set of light transmitting sections. Each of the first and second set of light transmitting sections is respectively in a portion that extends along a first side and a second side which is opposite to the first side of the display region and corresponds to the dummy pixel unit.
Description
CROSS REFERENCE TO RELATED APPLICATIONS[0001]This patent application is a National Stage Entry of PCT / CN2017 / 115878 filed on Dec. 13, 2017, which claims the benefit and priority of Chinese Patent Application No. 201710134007.6 filed on Mar. 8, 2017, the disclosures of which are incorporated herein by reference in their entirety as part of the present application.BACKGROUND[0002]The present disclosure relates to the field of display technology. Specifically, the disclosure relates to a color film substrate, a display panel, and a method for detecting a display panel.[0003]Defective lines may appear in the display device. The conventional method of confirming the defective line identifier of the display device is accomplished by using a lighter to light up the screen marker and a microscope with a reflection light to search the defective line. This method requires the use of a lighter and a microscope at the same time. It is necessary to confirm the identifier of defective lines one b...
