Micro LED Pixel Circuit with Threshold Voltage Compensation

Abstract

Display is used in various electronic devices such as computer monitors, smartphones, and TVs. Numerous researchers have made significant advancements in display technologies, including liquid crystal displays, organic light-emitting diode displays, and micro light-emitting diode displays, which now play pivotal roles in everyday life and a wide range of industries. Although widely adopted, organic light-emitting diode displays exhibit susceptibility to oxygen and moisture, leading to luminance deterioration and degradation. Hence, researchers are exploring micro light-emitting diode displays as the next-generation solution to address these limitations. This study delves into the pixel circuit design for micro light-emitting diode displays, with the primary goal of implementing threshold voltage compensation.
