Method, system and dynamically monitoring and calibrating display tiles

A method, system and apparatus for dynamically monitoring and calibrating display tiles are provided. The apparatus comprises: an array of light emitting devices; one or more light emitting devices paired with light emitting devices of the array; one or more sensors configured to detect an optical characteristic and/or an electrical characteristic of the one or more paired light emitting devices; and, circuitry configured to: drive the array; drive each of the one or more further light emitting devices under same conditions as light emitting devices of the array; temporarily drive each of the one or more paired light emitting devices under different conditions from the array; and, adjust driving of the array based on the optical characteristic and/or electrical characteristic of the one or more paired light emitting devices detected at sensor(s) when the one or more paired light emitting devices are driven under the different conditions..

Electronic circuit, driving the same, electro-optical device, and electronic apparatus

At a writing time, a first transistor 412 is turned on so that a data signal xj is supplied to one end of a capacitor 420. At this time, since a second transistor 414 is turned off, driving current does not flow to an organic light emitting diode (oled) device 430.
