[0014] In short, this difference in luminance between pixels due to the above-mentioned crosstalk phenomenon is contrary to the intention of the designer
[0015] Although in the above description, an organic electroluminescent device was taken as an example, crosstalk is a phenomenon commonly encountered in other light emitting devices

Abstract

The present invention is directed to a light emitting device and a method of driving the same where a cross-talk problem can be overcome. A light emitting device of the present invention comprises a display panel including a plurality of scan lines disposed in a first direction; a plurality of data lines disposed in a second direction, wherein the second direction is different from the first direction; and a plurality of pixels that are defined as overlying areas of the plurality of scan lines and the plurality of data lines; and a cross-talk preventing circuit configured to provide the plurality of scan lines with compensating currents according to display data provided by an outside device, whereby a total current passing through each scan line have substantially the same value.

Description

Technical field [0001] The present invention relates to a light-emitting device and a driving method thereof, in particular to a light-emitting device without crosstalk phenomenon, and a method for driving such a light-emitting device. Background technique [0002] An organic electroluminescence device is a light-emitting device that emits light using a specific voltage applied to it. [0003] FIG. 1A is a block diagram showing an organic electroluminescence device; FIG. 1B is an equivalent circuit diagram of some pixels in FIG. 1A. [0004] 1A, the organic electroluminescence device includes a display screen 100, a scan driving circuit 102, a data driving circuit 106, and a controller 104. [0005] The display screen 100 includes a plurality of pixels E11 to E44, which are defined as overlapping areas of the data lines D1 to D4 and the scan lines S1 to S4. [0006] For example, in the case where a voltage of 20V is applied to the data lines D1 to D4 and a voltage of 0V is applie...
