Embodiment Construction

[0041] Hereinafter, the inventive concept will be explained in detail with reference to the accompanying drawings.

[0042] figure 1 A display device 10 according to an embodiment of the inventive concept is shown.

[0043] refer to figure 1 , the display device 10 includes a display panel 100 and a display panel driver. The display panel driver includes a driving controller 200, a gate driver 300, a gamma reference voltage generator 400, and a data driver 500, and the gate driver 300 may be integrally formed in the display panel 100 but is not necessarily integrally formed in the display panel 100. form.

[0044] For example, the driving controller 200 and the data driver 500 may be integrally formed. For example, the driving controller 200, the gamma reference voltage generator 400, and the data driver 500 may be integrally formed. A driving module including at least the integrally formed driving controller 200 and the data driver 500 may be referred to as a timing contro...

Abstract

Provided is a data driver. The data drver includes a plurality of amplifiers configured to output a plurality of data voltages to a plurality of data lines. The amplifiers are configured to output the data voltages to the corresponding data lines in a writing mode. Only one of the plurality of amplifiers is configured to output a sensing data voltage to the plurality of data lines in a sensing mode.

Description

technical field [0001] The inventive concept relates to a data driver, a display device including the data driver, and a method of sensing a threshold voltage of a pixel using the display device. More particularly, embodiments of the inventive concept relate to a data driver outputting a sensing data voltage using only one output amplifier, a display device including the same, and a method of sensing a threshold voltage of a pixel using the display device. Background technique [0002] Generally, a display device includes a display panel and a display panel driver. The display panel includes a plurality of gate lines and a plurality of data lines. A display panel driver includes a gate driver and a data driver. The gate driver outputs gate signals to gate lines. The data driver outputs data voltages to the data lines. [0003] In the write mode, the data driver may output data voltages to the display panel. In the sensing mode, the data driver may output a sensing volta...
