1results about How to "Avoid displaying incorrectly" patented technology

The application relates to a light-emitting diode test circuit, a driving chip, a display module and a display panel. The light-emitting diode test circuit comprises: a plurality of first conductive elements, each first conductive element being used for corresponding connection with an anode of each light-emitting diode on a display module to be tested; a plurality of second conductive elements, each second conductive element being used for corresponding connection with a cathode of each light-emitting diode on the display module to be tested; a first conductive test element, which is connected with each first conductive element and is used for receiving a first driving voltage provided by an external test device; and a second conductive test element, which is connected with each second conductive element and is used for receiving a second driving voltage provided by the external test device, wherein the first driving voltage is greater than the second driving voltage. By using the above light-emitting diode test circuit, the number of top pins of a detection device can be reduced, and thus the detection cost is reduced.
