Embodiment Construction

[0032] Hereinafter, some embodiments of the present disclosure will be described in detail with reference to illustrative drawings. It should be noted that, in terms of adding reference numerals to constituent elements in the drawings, similar constituent elements are denoted by similar reference numerals whenever, even when shown in different drawings. In the following description of the present disclosure, when it is determined that a detailed description of a related known configuration or function makes the present disclosure unclear, the detailed description will thus be omitted.

[0033] In describing the constituent elements of the present disclosure, terms such as first, second, A, B, (a), and (b) may be used. These terms are used only to distinguish one constituent element from another constituent element, and are not intended to limit the nature, sequence or order of the constituent elements. It should be understood that when a constituent element is described as be...

Abstract

The invention provides a technique capable of adjusting a frequency of a sampling clock for pixel sensing according to configuration information.

Description

technical field [0001] The present disclosure relates to a technique for sensing characteristics of pixels disposed on a display panel and a technique for driving the display panel. Background technique [0002] The display device includes a panel driving device, such as a driving device including a source driver and a timing controller, that controls the brightness of pixels disposed on the panel. [0003] The panel driving device determines data voltages according to image data and supplies the data voltages to pixels, thereby controlling brightness of each pixel. [0004] Even when receiving the same data voltage, the luminance of a pixel may vary according to the characteristics of the pixel. For example, a pixel includes a driving transistor, and when the threshold voltage of the driving transistor is changed, even if the same data voltage is supplied, the brightness of the corresponding pixel can be changed. If the panel driving device does not consider such characte...
