20180061367 | DISPLAY DEVICE - A display device includes a display panel, a first flexible film, and a second flexible film. The display panel includes a non-display area outside a display area. The first flexible film is attached to a first side surface of the display panel. The second flexible film is attached to a second side surface of the display panel. The display panel includes a signal line, a pad electrode, and a side surface connection electrode. The signal line is in the display area and connects the first and second flexible films. The pad electrode extends from the signal line. The side surface connection electrode is on the first and second side surfaces and directly contacts the pad electrode. The first flexible film and the second flexible film are coupled to the side surface connection electrode and are electrically connected to the signal line. | 2018-03-01 |
20180061368 | DISPLAY APPARATUS - According to an aspect, a display apparatus includes: an image display panel including a plurality of pixels and displaying an image; and a signal processor generating a second signal by multiplying signal values for a plurality of sub-pixels making up each of the plurality of pixels by a gain, the signal values being included in a first signal that is an input signal of the image. The the signal processor calculates a luminance of each of the plurality of pixels based on the signal values of the sub-pixels included in the respective pixels. The signal processor increases the gain by which the signal values of the sub-pixels of the pixel having a luminance greater than a first luminance threshold are multiplied, in accordance with the luminance of the corresponding pixel. | 2018-03-01 |
20180061369 | ELECTRONIC APPARATUS AND RECORDING MEDIUM - An electronic apparatus of the present disclosure includes: a communicator comprising communication circuitry configured to wirelessly communicate with one or more external apparatuses; a signal processor configured to process data; and a controller configured to control an external apparatus to be designated as a transmitter for transmitting data and the electronic apparatus to be designated as a receiver for receiving the data from the transmitter if it is determined that the external apparatus is within a preset distance of the electronic apparatus and the external apparatus is moving. | 2018-03-01 |
20180061370 | DISPLAY SYSTEM, DISPLAY DEVICE, CONTROLLER, METHOD OF CONTROLLING DISPLAY DEVICE, AND PROGRAM - A display system includes a remote controller that includes a communication unit that transmits operation data to a projector, and an operation unit that receives an operation. The projector includes a remote controller light receiving unit that receives the operation data transmitted from the remote controller, a communication I/F unit that communicates with projectors, and a display unit that displays one setting screen selected from among a plurality of setting screens constituting a hierarchical structure in a case where the display unit is selected as an object to be set by the remote controller. The projector transmits an item identifier indicating a hierarchy of the setting screen being currently displayed to the projectors in a case where a switching instruction for switching an object to be set to the projectors is received from the remote controller during the display of the setting screen. | 2018-03-01 |
