The present disclosure relates to a display panel and a display device using the same, and includes a first pixel area in which pixels connected to a first cathode electrode are disposed, and a second pixel area in which pixels connected to a second cathode electrode are disposed. A data voltage of pixel data to be written to a pixel in the second pixel area is applied to a first gate electrode of a driving element disposed in the second pixel area. A compensation voltage for increasing the luminance of the second pixel area is applied to the gate electrode of the driving element.

This application claims priority to and the benefit of Republic of Korea Patent Application No. 10-2020-0143009, filed Oct. 30, 2020, the disclosure of which is hereby incorporated herein by reference in its entirety.
The present disclosure relates to a display panel and a display device using the same.
Electroluminescent display devices are roughly classified into inorganic light emitting display devices and organic light emitting display devices depending on the material of an emission layer. The organic light emitting display device of an active matrix type includes an organic light emitting diode (hereinafter, referred to as “OLED”) that emits light by itself, and has an advantage in that the response speed is fast and the luminous efficiency, luminance, and viewing angle are large. In the organic light emitting display device, the OLED is formed in each pixel. The organic light emitting display device has a fast response speed, excellent luminous efficiency, luminance, and viewing angle, and has excellent contrast ratio and color reproducibility since it can express black grayscales in complete black.
The above and other objects, features, and advantages of the present disclosure will become more apparent to those of ordinary skill in the art by describing exemplary embodiments thereof in detail with reference to the attached drawings, in which:
FIG. 1 is a cross-sectional view schematically showing a display panel according to an embodiment of the present disclosure;
FIG. 2 is a plan view showing an area in which a sensor module is disposed in a screen of a display panel according to an embodiment of the present disclosure;
The advantages and features of the present disclosure and methods for accomplishing the same will be more clearly understood from embodiments described below with reference to the accompanying drawings. However, the present disclosure is not limited to the following embodiments but may be implemented in various different forms. Rather, the present embodiments will make the disclosure of the present disclosure complete and allow those skilled in the art to completely comprehend the scope of the present disclosure. The present disclosure is only defined within the scope of the accompanying claims.
The shapes, sizes, ratios, angles, numbers, and the like illustrated in the accompanying drawings for describing the embodiments of the present disclosure are merely examples, and the present disclosure is not limited thereto. Like reference numerals generally denote like elements throughout the present specification. Further, in describing the present disclosure, detailed descriptions of known related technologies may be omitted to avoid unnecessarily obscuring the subject matter of the present disclosure.
The terms such as “comprising,” “including,” “having,” and “comprising” used herein are generally intended to allow other components to be added unless the terms are used with the term “only.” Any references to singular may include plural unless expressly stated otherwise.
