Abstract: A transparent display panel and a transparent display device including the same are disclosed. The transparent display panel includes a display region and a non-display region. The display region includes a plurality of light-emitting regions, a plurality of transmissive regions, a plurality of line regions spaced from each other and arranged in one direction, and a plurality of pixel circuit regions electrically connected to the light-emitting regions respectively to drive the light-emitting regions. Alternately-arranged adjacent line regions include alternately-arranged adjacent VSS voltage connection line and VDD voltage connection line, respectively. Thus, a new pixel arrangement structure that may increase or maximize a transparent area of a bezel and reduce or minimize a haze value without reducing transmittance of the display region may be realized.

Abstract: Various embodiments relate to an EM signal control circuit, an EM signal control method, and an organic light emitting display device. The EM signal control circuit according to an embodiment of the present invention includes additional elements (e.g., a transistor and a capacitor) configured to separate a set signal from a gate electrode of a transistor coupled to an output node and to stably keep turn-off of a transistor coupled to the output node. Voltage levels of a first emission power source and a first gate power source may be set differently from each other according to the present invention. Therefore, despite of a threshold voltage change of a transistor coupled to an output node, the transistor may remain turned off stably, thereby improving the reliability of the EM signal.

Abstract: A transparent display panel and a transparent display device including the same are disclosed. In a transparent display panel, a VSS voltage line does not surround an outer periphery of a display region. Rather, upper and lower VSS voltage lines respectively disposed on upper and lower sides to the display region are electrically connected to each other via at least one VSS voltage connection line extending across the display region. Thus, left and right non-transparent and thick VSS voltage lines disposed on the left and right sides to the display region may be omitted. Thus, a transparent region of the transparent display panel and a bezel of a transparent display device may be increased or maximized or the bezel thereof may be made slim.

Abstract: In a transparent display panel, a GIP region acts as a transmissive region, thereby increasing or maximizing a transmissive area in the GIP region. To this end, a line for VSS voltage application is disposed in a display region. Thus, a non-transparent thick line for applying the VSS voltage is not disposed in an upper portion of a GIP circuit region. Thus, a transparent bezel in which the GIP region acts as the transmissive region is implemented. Further, a GIP input signal line region and a GIP output signal line region constitute different layers, thereby to maximize a spacing between GIP input signal lines, resulting in increasing or maximizing a transmissive area in the GIP circuit region.
