This paper proposes the novel pixel circuit for Micro‐LED display. In order to solve screen distortion, when grayscale representation of Micro‐LED is generated, the emission time of Micro‐LED is controlled using the Pulse Width Modulation (PWM) method. In addition, we utilize the LTPO backplane technology to reduce leakage current from storage capacitor.
