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.

摘要： An object of the present invention is to achieve an advanced input operation without complicating image processing. A display device of the present invention includes a display unit, an optical input unit, and an image processor. The display unit displays an image on a display screen. The optical input unit captures an image of an object approaching the display screen. The image processor detects that the object comes into contact with the display screen on the basis of a captured image captured by the optical input unit, and then performs image processing to obtain the position coordinates of the object. In the display device, the image processor divides the captured image into a plurality of regions, and performs the image processing on each of the divided regions.

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.
