High-speed electrical testing system applied to printed display panel

High-speed electrical testing system applied to printed display panel, comprising:

• a first substrate comprising a conductive layer;
• a detection probe array disposed opposite to the conductive layer, wherein during detection of the printed display panel, the printed display panel is disposed between the first substrate and the detection probe array, and wherein light-emitting pixels of the printed display panel have a sandwich layered structure comprising an anode terminal, a light-emitting layer, and a cathode terminal;
• a high-frequency AC power supply module electrically connected to both the detection probe array and the conductive layer, the high-frequency AC power supply module configured to supply power to form a first alternating electric field between the detection probe array and the conductive layer, the first alternating electric field causing the printed display panel to exhibit electroluminescence when a first direction from the anode terminal to the cathode terminal of a light-emitting pixel coincides with an electric field direction of the first alternating electric field;
• an electrical signal measurement module disposed adjacent to the conductive layer and configured to collect corresponding electrical signal information of the printed display panel;
• an optical signal measurement module disposed on one side of the first substrate and configured to collect corresponding light emission information of the printed display panel;
• and an electrically controlled displacement module configured to carry and transport the first substrate or the detection probe array to align the detection probe array with the printed display panel during detection. The high-speed electrical testing system is configured as follows:
• control the optical signal measurement module to collect the light emission information during a half-cycle corresponding to a downward electric field direction of the first alternating electric field, in response to the anode terminal of each light-emitting pixel in the printed display panel being located above the cathode terminal;
• otherwise, control the optical signal measurement module to collect the light emission information during a half-cycle corresponding to an upward electric field direction of the first alternating electric field.
