Publication number: 20230317006Abstract: Embodiments relate to a display device including pixels that compensate a threshold voltage of a driving transistor, the pixels arranged in a plurality of rows. The gate of the driving transistor of each pixel is coupled to a pixel data switch and a reference voltage switch, configured to selectively provide pixel data provided via a data line and a reference voltage provided via a separate reference voltage line to the gate of the driving transistor, respectively. As pixel data and the reference voltage are provided to the driving transistor via separate lines, the compensation period of the pixel may overlap in time with a data writing period of pixels of a previous row of the display device, increasing the rate at which the display device is able to program the pixels of each row.Type: ApplicationFiled: March 16, 2023Publication date: October 5, 2023Inventors: Gyungmin Kim, Min Hyuk Choi, Takanori Shibasaki
