| contents | A new gate driver employing linearly sweep signal generated module for high‐resolution micro‐LED display with line‐by‐line pulse width modulation driving method Li‐Rong Zhang Xiang‐Lin Mei Zhao‐Hua Zhou Lei Zhou Chun Liu Miao Xu Lei Wang Wei‐Jing Wu Jun‐Biao Peng Journal of the Society for Information Display AbstractA new gate driver with metal oxide thin‐film transistors (MO‐TFTs) has been presented for micro‐light‐emitting diode (Micro‐LED) display. The proposed gate driver employing linearly decreasing sweep signal generated module could realize the line‐by‐line pulse width modulation (PWM) driving method, which is valuable for application in high‐resolution Micro‐LED display compared with the conventional driving method employing global sweep signal. A simple Micro‐LED pixel circuit including an inverter module driven by the analog PWM method is employed to demonstrate the feasibility of the proposed gate driver. A 10 × 10 green Micro‐LED display array has been fabricated with MO‐TFTs backplane technology. It is shown that a 10‐μs width pulse and linearly scanning sweep signal can be successfully output. Consequently, the pixel circuit array can be driven properly under analog line‐by‐line PWM driving method. 10.1002/jsid.2002 http://onlinelibrary.wiley.com/termsAndConditions#vor |
