Embodiment Construction

[0034] figure 1 is an illustration of an exemplary display system 50 . The display system 50 includes an address driver 8 , a data driver 4 , a controller 2 , a memory storage device 6 and a display panel 20 . The display panel 20 includes an array of pixels 10 arranged in rows and columns. Each of the pixels 10 is individually programmable to emit light having an individually programmable brightness value. The controller 2 receives digital data indicative of information to be displayed on the display panel 20 . The controller 2 sends a signal 32 to the data driver 4 and a scheduling signal 34 to the address driver 8 to drive the pixels 10 in the display panel 20 to display the indicated information. The plurality of pixels 10 associated with the display panel 20 thus comprises a display array ("display screen") adapted to dynamically display information according to input digital data received by the controller 2 . The display screen may display video information eg from ...

Abstract

A system for driving a display including a plurality of pixel circuits arranged in an array, each of the pixel circuits including a light emitting device and a drive transistor for delivering a drive current through the light emitting device. A method of measuring characteristics of circuit elements of pixels sharing a monitor line includes controlling biases to selectively disconnect circuit elements or to make the response of these circuit elements known while other circuit elements of interest are measured.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Canadian Application No. 2,894,717, filed June 19, 2015, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure generally relates to circuits for use in displays, and methods of driving, calibrating, and programming displays, particularly displays such as active matrix organic light emitting diode displays. Background technique [0004] Displays may be formed from an array of light emitting devices, each controlled by a separate circuit (i.e., a pixel circuit) with transistors for selectively controlling the circuit to be programmed with display information and to to emit light for the above display information. Thin film transistors ("TFTs") fabricated on a substrate can be incorporated into such displays. As displays age, TFTs tend to exhibit non-uniform behavior across the display panel and over time. Compensation techniques c...
