Display device and electronic apparatus
View Patent ↗According to an aspect, a display device includes an image display panel, data lines, and scan lines. The image display panel includes arrays of pixels including a plurality of sub-pixels. The arrays of pixels include cyclically arranged columns of first columns each of which includes first sub-pixels, second columns that include second sub-pixels, and third columns. Third sub-pixels and fourth sub-pixels are alternately arranged in the third columns in the direction along the third columns, and are alternately arranged in a direction along the row in the same row of the third columns. Each of the scan lines is coupled to either of the third sub-pixels adjacent thereto or the fourth sub-pixels adjacent thereto, as sub-pixels to be selected thereby.
1. A display device comprising:
an image display panel that includes arrays of pixels including a plurality of sub-pixels, the arrays of pixels including cyclically arranged columns of first columns that include first sub-pixels, second columns each of which is arranged next to the corresponding first column and includes second sub-pixels, and third columns each of which is arranged next to the corresponding second column;
a display function layer that has an image display function of displaying an image on the image display panel;
a plurality of data lines each coupled to one of the first columns, the second columns, and the third columns;
a control unit that drives the display function layer based on image signals by a column inversion driving method in which voltage applied to the data lines are different between the adjacent sub-pixels or between the adjacent pixels, and polarities of the applied voltages are inverted at a predetermined period; and
a plurality of scan lines with which the control unit sequentially selects each row of the sub-pixels, wherein
third sub-pixels and fourth sub-pixels are alternately arranged in the third columns in the direction along the third columns, and the third sub-pixels and the fourth sub-pixels are alternately arranged in a direction along the row in the same row of the third columns,
each of the scan lines is coupled to the first sub-pixels and the second sub-pixels of the same row,
each of the scan lines is coupled to the third sub-pixels or the fourth sub-pixels adjacent to the each of the scan lines, and
the sub-pixels of the third columns in the same row are coupled to alternately different scan lines both of which are adjacent to the sub-pixels of the same row.
2. The display device according to claim 1 , wherein
the control unit transmits image signals to be transmitted to the sub-pixels of every other one of the third columns arranged in a direction along the row so as to shift the image signals from the other sub-pixels in the same row by one horizontal pixel.
3. The display device according to claim 1 , wherein
the scan lines are coupled to the third sub-pixels of both adjacent rows, or the fourth sub-pixels of both adjacent rows.
4. The display device according to claim 1 , further comprising
a touch detection device attached or integrated on the image display panel, the touch detection device being capable of detecting an external approaching object that externally comes close.
5. An electronic apparatus including a display device, the display device comprising:
an image display panel that includes arrays of pixels including a plurality of sub-pixels, the arrays of pixels including cyclically arranged columns of first columns each of which includes first sub-pixels, second columns each of which is arranged next to the corresponding first column and includes second sub-pixels, and third columns each of which is arranged next to the corresponding second column;
a display function layer that has an image display function of displaying an image on the image display panel;
a plurality of data lines each coupled to one of the first columns, the second columns, and the third columns;
a control unit that drives the display function layer based on image signals by a column inversion driving method in which voltage applied to the data lines are different between the adjacent sub-pixels or between the adjacent pixels, and polarities of the applied voltages are inverted at a predetermined period; and
a plurality of scan lines with which the control unit sequentially selects each row of the sub-pixels, wherein
third sub-pixels and fourth sub-pixels are alternately arranged in the third columns in the direction along the third columns, and the third sub-pixels and the fourth sub-pixels are alternately arranged in a direction along the row in the same row of the third columns,
each of the scan lines is coupled to the first sub-pixels and the second sub-pixels of the same row,
each of the scan lines is coupled to the third sub-pixels or the fourth sub-pixels adjacent to the each of the scan lines, and
the sub-pixels of the third columns in the same row are coupled to alternately different scan lines both of which are adjacent to the sub-pixels of the same row.
