摘要： In making a contact determination between an object and a display screen, a display apparatus of the present invention is capable of adjusting a region on which to make a contact determination in response to the displayed image in a liquid crystal panel, so that the influence by the displayed image can be suppressed. Moreover, for simplifying the contact determination process, the display apparatus sets solid a region in the picked-up image that is not a target of the contact determination, with a predetermined gradation value.

摘要： A liquid crystal panel brightness controller notifies a backlight controller that an illuminance of ambient light is equal to or less than a threshold value. Upon notification, the backlight controller causes invisible light emitted, for example. The invisible light passes through a liquid crystal panel and is reflected by an imaging target and is received by photosensors. Accordingly, the decrease in the amount of the visible light received by photosensors is compensated. As a result, an image with a high S/N ratio is obtained.

摘要： In order to maintain display performance of a display device, the display device includes an optical sensor disposed across three sub-pixels of red, green and blue colors in each pixel. This configuration makes it possible to adjust the aperture ratios of the respective sub-pixels, and thus to make the amount of light passing through the respective sub-pixels closer to one another. In other words, the white balance can be maintained.

摘要： In order to improve accuracy in determining whether or not an object touches a display screen, a display device includes a display unit and a processor. The display unit includes an image display unit which displays an image on a display screen, an optical input unit which picks up an image of an object adjacent to the display screen and a capacitive coupling detector which detects a capacitive coupling to the object adjacent to the display screen. The processor determines that the object touches the display screen by using, and concurrently calculates the coordinates touched by the object by using the capacitive coupling detected by the capacitive coupling detector, and the image picked up by the optical input unit.
