发明名称 Detecting circuit
摘要 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.

主权项 1. A detecting circuit for detecting a feedback voltage of a pixel circuit, comprising: a converting unit electrically connected to the pixel circuit for performing an analog-to-digital operation to convert the feedback voltage into a digital signal; a control chip electrically connected to the converting unit for controlling the converting unit to perform the analog-to-digital operation, and processing the digital signal to generate a display information; and a display unit electrically connected to the control chip for displaying a voltage value of the feedback voltage according to the display information; wherein the control chip controls the converting unit to sample the feedback voltage a number of times so as to generate a corresponding number of digital outputs, and then averages the digital outputs to generate the display information.
