This application is the National Stage of PCT/US2021/037065 filed on Jun. 11, 2021, which claims priority of the U.S. Provisional Application No. 63/038,634 filed on Jun. 12, 2020, the disclosure of which is incorporated by reference.
The present disclosure relates to circuitry for controlling switching of a transistor and, more particularly, for controlling operation of display devices and other electronic devices that include transistors.
Components provided in some electronic devices perform a variety of functions. For example, display devices include arrays of lighting elements (e.g., organic light emitting diodes (OLEDs), traditional light emitting diodes (LEDs), or micro light emitting diodes (MLEDs)) that are part of a pixel in the display. Control circuitry is coupled to the lighting elements to control the operational state of the lighting elements to emit light in response to a signal.
Demand has driven the design of circuitry to have increasingly smaller size while also maintaining or improving the level of performance. As a result, a density of components has also increased. In these electronic device designs, materials used as conductors and the substrates upon which the circuits are formed are typically brittle and rigid. The combination of increased density and rigidity has resulted in fixed shapes and forms. In current display devices, for instance, the density of pixels has increased dramatically in recent years, providing impressive resolution and contrast; however, the shape and form of such display devices is fixed.
