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.

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: A display device includes a diffusion layer providing a single well, an optical element configured to receive light and output the received image light including a concentric series of lens segments made up of active facets, and a waveguide having an in-coupling grating and a waveguide body optically coupled to the image light, where a polarizing component is disposed over an output surface of the optical element. A method to improve a yield of silicon backplane displays includes connecting a diode having a resolution to a backplane and repairing a defect on a pixel display area by dividing the pixel display area into at least one subcircuit, while improving geometry stylization transfer for 3D models of real-world environments. A method for suppressing crosstalk for user conversations includes receiving multiple speech signals captured by multiple microphones and generating directional data for the multiple speech signals based on spatial filtering.

Abstract: Described is a system including a display, a display controller, and control logic communicatively coupled to the display. The display controller determines, based on coordinates of a focus point on the display, boundaries of a first image region and a second image region in an output image to be rendered. The focus point is determined through tracking an eye movement of a user viewing the display. The first image region has a higher resolution than the second image region. The display controller is configured to send image data together with control signals to the control logic. The control signals cause the control logic to render the output image on the display using the image data. As part of rendering the second image region, the control logic outputs a shared signal onto signal lines that are coupled to light sources in a group of adjacent rows or columns.
