Abstract

The light emitting display panel includes a plurality of pixels, a plurality of gate lines transmitting gate signals to the plurality of pixels, a plurality of data lines transmitting data voltages to the plurality of pixels, and sensing lines coupled to a plurality of light emitting devices respectively included in the plurality of pixels. Each of the plurality of pixels includes: a light emitting device; a sensing control transistor including a first terminal coupled to the first terminal of the light emitting device and a gate coupled to a sensing control line; and a sensing switching transistor including a first terminal coupled to the second terminal of the sensing control transistor, a second terminal coupled to the sensing line, and a gate coupled to the sensing switching line.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2020-0148837 filed on November 9, 2020, which is incorporated herein by reference as if fully set forth herein. technical field [0003] The present disclosure relates to a light emitting display panel and a light emitting display device including the same. Background technique [0004] A light emitting display device is a display device that emits light by using a light emitting device, and includes a light emitting display panel including a plurality of light emitting devices. [0005] As the light emitting display device continues to be used, the light emitting device deteriorates, and thus the characteristics of the light emitting device change. Therefore, the light emitting device cannot emit light normally. [0006] Sensing of the light emitting device is performed to check the degree of change in characteristics of the light emitting devic...
