A detecting circuit for detecting a feedback voltage of a pixel circuit includes a converting unit, a control chip and a display unit. The converting unit electrically connected to the pixel circuit performs an analog-to-digital operation to convert the feedback voltage into a digital signal. The control chip electrically connected to the converting unit controls the converting unit to perform the analog-to-digital operation and processes the digital signal to generate a display information. The display unit electrically connected to the control chip displays a voltage value of the feedback voltage according to the display information. |
