摘要： Embodiments of the present disclosure relate to a data driving circuit and a display device. In the process of a display device converting an image data received from an outside into a data signal supplied to a data driving circuit, a final color temperature target represented by the image is variably set based on a panel driving current, so that the power consumption of a display panel displaying an image can be minimized. In addition, since the final color temperature target is varied, the luminance of the image and the user's recognition level are maintained constant, thereby improving the efficiency of the display device.

摘要： A display apparatus includes a display panel having a front area and a side area, a main body supporting the display panel, an auxiliary member arranged inside the main body, and a semi-transmissive mirror arranged between the auxiliary member and the front area, wherein the side area of the display panel may be arranged inside the main body to face the semi-transmissive mirror. Since an image partially emitted from the display panel may be reflected toward the front area, auxiliary members such as a camera, an illumination sensor, and a proximity sensor may be arranged inside the main body (or below a display) to embody a full screen display, whereby a user's satisfaction may be enhanced and a manufacturing process may be simplified.

摘要： A display device capable of reducing a non-display area includes a substrate hole surrounded by light emitting elements, and a moisture penetration preventing layer disposed between an inner dam surrounded by the light emitting elements and the substrate hole. Accordingly, it is possible to prevent damage to light emitting stacks caused by external moisture or oxygen. Since the substrate hole is disposed within an active area, a reduction in non-display area is achieved.
