Embodiment Construction

[0047] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. In this specification, when referring to a component (or region, layer, section) being “on,” “connected to,” or “combined with” another component, the terms “on,” "Connected to" or "combined with" means that a component may be directly connected to / combined with another component, or means that a third component may be provided between the component and another component.

[0048] The same reference numerals correspond to the same components. Also, in the drawings, thicknesses, ratios, and sizes of components are exaggerated in order to effectively describe technical details. The term "and / or" includes all combinations of one or more combinations that the relevant configuration may define.

[0049]Although terms such as first and second may be used to describe various components, the components are not limited by the above-mentioned terms. These terms are...

Abstract

The present invention relates to a display device and a sensing method, and more particularly, to a method for sensing a mobility of a driving TFT of a sub-pixel while an image is being driven by the display device, and a display device performing the method. A sensing method for compensation, performed when a display device is being driven, includes: charging a node M of a shift register A connected to a jth gate line of a display panel in an Nth frame period; in the Nth frame period, charging a node M of a shift register B connected to the Kth gate line of the display panel; sensing a sub-pixel connected to the j-th gate line in a next blank period after the N-th frame period; and sensing the sub-pixel connected to the Kth gate line in the blank period.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2019-0178288 filed on December 30, 2019, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a display device and a sensing method, and more particularly, to a method for sensing mobility of a driving TFT of a sub-pixel while an image is being driven by the display device, and a display device performing the method. Background technique [0004] With the development of the information society, various types of display devices are being developed. Recently, various display devices are being used, such as liquid crystal displays (LCDs), plasma display panels (PDPs), and organic light emitting displays (Organic Light Emitting Displays (OLEDs). [0005] An organic light emitting device constituting an OLED emits light by itself, and thus does not require a separat...
