Abstract

A display unit with a touch detection function includes: a plurality of touch detection electrodes arranged side by side to extend in a direction, each of the touch detection electrodes being formed in a predetermined electrode pattern including electrode portion and opening portion and outputting a detection signal, based on a variation in capacitance due to an external proximity object; and a plurality of display elements formed in a layer different from a layer of the touch detection electrodes, a predetermined number of the display elements being arranged within a width dimension of a region corresponding to each of the touch detection electrodes. The predetermined electrode pattern corresponds to a layout pattern of the display elements.

Claims (21)

1. A display unit with a touch detection function, the display unit comprising:

a plurality of pixels arranged in a pixel layer in a matrix along a first direction and a second direction, the pixels including a red pixel, a green pixel, and a blue pixel;

a plurality of touch detection electrodes that are arranged along the first direction with a predetermined gap between them and that extend in the second direction, in a touch detection region; and

a plurality of dummy electrodes that are arranged in a matrix along the first direction and the second direction in a dummy region that is in a display region except in the touch detection region, the dummy electrodes being arranged electrically isolated from each other;

wherein,

the touch detection region is spaced apart from the dummy region by a first gap that extends in the second direction,

a first gap pixel is a red pixel located within the first gap,

the first gap is substantially centered with respect to the first gap along the second direction, and

in the first direction, the first gap pixel is adjacent to the blue pixel disposed in the touch detection region and adjacent to the green pixel disposed in the dummy region.

2. A display unit with a touch detection function, the display unit comprising:

a plurality of pixels arranged in a pixel layer in a matrix along a first direction and a second direction, the pixels including a red pixel, a green pixel, and a blue pixel;

a plurality of touch detection electrodes that are arranged along the first direction with a predetermined gap between them and that extend in the second direction, in a touch detection region; and

a plurality of dummy electrodes that are arranged in a matrix along the first direction and the second direction in a dummy region that is in a display region except in the touch detection region, the dummy electrodes being arranged electrically isolated from each other;

wherein,

the touch detection region is spaced apart from the dummy region by a first gap that extends in the second direction,

a first gap pixel is a red pixel located within the first gap,

the first gap is substantially centered with respect to the first gap along the second direction,

the dummy electrodes in the dummy region are spaced apart from each other by a second gap that extends in the second direction,

a second gap pixel is a red pixel located within the second gap as viewed in plan view,

the second gap pixel is substantially centered with respect to the second gap along the second direction, and

in the first direction, the second gap pixel is adjacent to the blue pixel disposed in the dummy region and adjacent to the green pixel disposed in the dummy region.
