• In this paper, a novel partial scan Gate Driver on Array (GOA) architecture with gate and cascade scan separated output (GCSS‐GOA) is proposed. Combined with a newly designed timing controller (TCON) IC and IP, dynamic local refresh at any position and with different refresh rate at different area on liquid crystal display (LCD) panel are achieved. The driving schemes for dynamic local refresh and the display image quality evaluation results are also presented. For power consumption, it can be reduced by up to 50% respectively for GOA and data drivers in dynamic local refresh mode under 60 Hz benchmark refresh rate. This technology is also applicable to OLED, LED, e‐paper and other display products. A novel partial scan GOA with gate and cascade scan separated output design is proposed. Combined with a newly designed TCON IC and IP, dynamic local refresh at arbitrary position and variable refresh rates on LCD panel are achieved. Power consumption of GOA and data drivers can be reduced by up to 50% respectively.
