Abstract: Embodiments relate to a display device with subpixels that share switch transistors that selectively connect sources of driving transistors to a high voltage source. Further, part of reset transistors or part of a select transistor may be shared across multiple subpixels. The reset transistor selectively connects an anode of an organic light emitting diode (OLED) to a low voltage source. The select transistor selectively passes through pixel data from a data line when a gate signal is received via a gate line. Driver transistors and capacitors of the subpixels are independent and not shared. In this way, the dimensions of the subpixels may be reduced and enable increase in the density of the pixels.

Abstract: Embodiments relate to a display device including pixels that compensate a threshold voltage of a driving transistor using the body effect. Pixel data for the driving transistor increases the source-bulk voltage of the driving transistor during a compensation period as a result of the body effect. A separate reference voltage is not received at the pixel for the purpose of compensating the threshold voltage of the driving transistor. The increased source-bulk voltage is then used in an emission period of the pixel to compensate for the threshold voltage of the driving transistor.
