Abstract: A display panel and display device are provided that may be capable of sensing an external light source, such as a laser. The display device may include a display panel including gate lines, data lines, and sub-pixels defined at intersections between the gate lines and the data lines; a light source-sensing circuit in an inactive area of the sub-pixels to sense an external light source; and a monochromatic color filter pattern disposed on a sensor transistor of the light source-sensing circuit. Thus, the incident amount of an external light source other than a laser can be reduced, and the incident amount of the laser can be increased. Accordingly, it may be possible to decrease an initial off-current caused by an external light source and improve the sensitivity in laser sensing. Thus, the size of the sensor transistor can be reduced and aperture ratio can be increased.

Abstract: An array substrate for LCD devices and a method of manufacturing the same are provided. By using a structure where an empty space is secured in a data line area as in a DRD structure in which the number of data lines is reduced by half, a capacitance is sufficiently secured by forming a sub storage capacitor in the data line area of the empty space, and thus, an area of a main storage capacitor can be reduced. Accordingly, the cost can be reduced, and moreover, an aperture ratio can be enhanced.

Abstract: A display device can include a display panel including a plurality of pixels configured to be driven in one of a driving period and a blank period, a timing controller configured to output a variable refresh rate (VRR) signal determining a refresh rate of the plurality of pixels and a video data signal, and a data driver configured to supply a data voltage to the plurality of pixels through a plurality of data lines, according to the VRR signal and the video data signal. The plurality of pixels can be driven at a first refresh rate or a second refresh rate which is lower than the first refresh rate, according to the VRR signal. Further, when the plurality of pixels are driven at the second refresh rate and the video data signal is a low grayscale video data signal, the output luminance of each of the plurality of pixels can be reduced during the blank period.
