Abstract: A display device includes a display panel including a plurality of pixels, and a panel driver configured to receive input data, and to drive the display panel based on the input data. The panel driver includes a partial still image detector configured to detect a still image data portion in the input data by determining whether at least a portion of the input data represents a still image, and a command decoder configured to extract command data from the input data by decoding the still image data portion in which the command data are encoded.

Abstract: A display device includes a substrate including a display region and a non-display region including sub-non-display regions extending from sides of the display region and separated from each other, a display layer provided on a surface of the substrate in the display region and including pixels, and wiring lines provided in the sub-non-display regions on the substrate and electrically connected to the pixels. The sub-non-display regions each includes a display connection region connected to the display region and at least one extension region extending from a part of the display connection region. The sub-non-display regions are bent and are disposed on a surface opposite to a surface, on which the display layer is disposed, in the display region. When the sub-non-display regions are bent, an extension region of one of the sub-non-display regions overlaps another extension region of another of the sub-non-display regions.

Abstract: A flat panel display device with an improved structure reducing the number of components and assembling processes comprises: a panel including a first substrate, an emission unit formed on the first substrate, and a second substrate coupled to the first substrate so as to seal the emission unit and including a flange portion having a first coupling hole; a monitor frame having a second coupling hole corresponding to the first coupling hole; and a fastener for coupling the panel and the monitor frame by being inserted into the first coupling hole. In this structure, the flange portion is used to couple the monitor frame to the panel, and thus a separate fixing frame is not used. The lack of need for the fixing frame leads to a fewer number of components and assembling processes.
