The liquid crystal panel assembly includes a liquid crystal panel configured to display an image, a backlight arranged in the rear of the liquid crystal panel and configured to supply light to the liquid crystal panel, a package module configured to package the liquid crystal panel and the backlight into one module, and at least one dummy member arranged to occupy a space provided in the rear of the backlight in the package module.
Abstract:
A display apparatus having a screen on which recording by a user's touch can be performed is provided. The display apparatus includes a display configured to provide the screen, an accommodator configured to accommodate the display and having a screen aperture formed thereon with a predetermined depth to expose the screen, a touch position sensor configured to sense the position of a touch device that is used by a user when a distance between the screen and the touch device is shorter than the predetermined depth, a vibration sensor mounted on the display and configured to sense vibration of the display due to a contact of the touch device with the screen, and a controller configured to control the display to perform recording on a point of the screen that corresponds to the sensed position of the touch device when the vibration is sensed.
Abstract:
A display apparatus is disclosed. The display apparatus includes a display panel, a photonic crystal array which is arranged on at least one side of the display panel and displays an image based on an applied voltage, an electrode which applies voltage to the photonic crystal array, and a controller which controls so that voltage is applied to the photonic crystal array based on image information displayed on the display panel.
Abstract:
A digital pen, a touch system and a method for providing information thereof are provided. The touch system may include a display apparatus and a digital pen having a battery. The digital pen may be configured to sense a battery status of the battery, generate a signal indicating a location of the stylus with respect to the display apparatus. The signal may have a frequency corresponding to the battery status, and transmit the signal to the display apparatus. The display apparatus may be configured to receive the signal, analyze the signal, and acquire the location of the stylus and the battery status.
Abstract:
A display apparatus, a controlling method thereof, and a display system are provided. According to the display apparatus, in response to detecting a plurality of input apparatuses having different touch patterns through a display allowing a touch and including a touch panel, the plurality of input apparatuses are identified using the detected touch patterns, and the display apparatus is controlled independently according to each of a plurality of touch interactions which are input through the plurality of input apparatuses.
Abstract:
An electronic conference apparatus, a method for controlling the same, and a digital pen are provided. The electronic conference apparatus includes a sensor configured to sense a touch point of a digital pen through first hand writer during a period in which handwriting is input to paper through second hand writer. The electronic conference apparatus further includes a controller configured to generate handwriting information based on the sensed touch point, and a communicator configured to transmit the handwriting information.
Abstract:
An input device, a display apparatus and a method of controlling the input device are provided. The input device includes: a communicator configured to communicate with a display apparatus; a sensor configured to sense a sound; a volume extractor configured to extract volume sections from the sound sensed by the sensor; and a controller configured to determine whether a peak level of each of the volume sections extracted by the volume extractor exceeds a threshold level, and in response to determining the peak level of a volume section among the volume sections exceeds the threshold level, control the communicator to generate an event signal for cancelling a job for a pattern image displayed on the display apparatus based on a touch input and transmit the event signal to the display apparatus.
Abstract:
A liquid crystal panel includes an upper plate, a lower plate, and a liquid crystal layer accommodated between the upper plate and the lower plate. The upper plate includes a front glass substrate, a color filter layer formed on a rear surface of the front glass substrate, and a front polarizing film is attached to a front surface of the front glass substrate. The color filter layer includes a plurality of N color filters and black matrices for separating the color filters from each other. A plurality of patterns for recognizing coordinates are provided on a front side of the upper plate in such a manner that the N color filters correspond to one of the plurality of patterns for recognizing the coordinates, where N is a natural number.
