Display module inspection device and display module inspection method

An inspection device, comprising:

• a display including a power supply, a circuit board having a stabilizer configured to stabilize the power supply, a display panel which is electrically connected to the circuit board and has a first electrode, and an input sensor which is disposed on the display panel and has a second electrode;
• and
• inspection logic configured to measure a value of capacitance between the first electrode and the second electrode of the display, wherein the inspection logic is configured to set a driving voltage of the power supply to a voltage in a first predetermined range.

An apparatus, comprising:

• inspection logic configured to determine existence of a defect in a display, the display including a power supply, a circuit board having a stabilizer configured to stabilize the power supply, a display panel which is electrically connected to the circuit board and has a first electrode, and an input sensor which is disposed on the display panel and has a second electrode,
• wherein the inspection logic comprises a frequency setter configured to set a driving frequency of the second electrode to a frequency in a first predetermined range, and wherein the inspection logic is configured to measure a value of capacitance between the first electrode and the second electrode of the display to determine existence of the defect.
