Display device with pixel inversion
View Patent ↗A display device includes pixels arranged in columns and rows, in which the pixels of a row can be selected by means of a row voltage supplied via control lines, and column voltages that correspond to the image data of the selected pixel to be displayed can be supplied via data lines, wherein mutually adjoining pixel groups arranged in a row or column, consisting of adjoining pixels of a row or column, are connected to adjoining control lines or data lines, as applicable, in alternation.
1. A display device with pixels arranged in columns and rows, in which the pixels of a row can be selected by means of a row voltage supplied via control lines, and column voltages that correspond to the image data of the selected pixel to be displayed can be supplied via data lines, wherein mutually adjoining pixel groups arranged in a row or column, consisting of adjoining pixels of a row or column, are connected to adjoining control lines or data lines, as applicable, in alternation, some of the control lines being connected to a plurality of delay units such that only every other control line is connected to a particular delay unit of the delay units and each of remaining control lines is not connected to any delay unit, the delay units being used to store row voltage values for the control lines connected to the delay units until a clock signal is supplied to the delay units.
2. A display device as claimed in claim 1 , characterized in that a pixel group comprises one pixel.
3. A display device as claimed in claim 1 , characterized in that mutually adjoining pixels of one row are alternately connected to the adjoining control lines.
4. A display device as claimed in claim 1 , characterized in that the pixels comprise switching elements with control terminals which are connected to the control lines and data terminals which are connected to the data lines.
5. A display device as claimed in claim 1 , characterized in that the rows and columns situated at the edges of the display device are covered.
6. A method of controlling a display device as claimed in claim 1 .
7. A display device as claimed in claim 1 , wherein the delay units are D-flip-flops.
8. A display device with pixels arranged in columns and rows, in which the pixels of a row can be selected by means of a row voltage supplied via control lines, and column voltages that correspond to the image data of the selected pixel to be displayed can be supplied via data lines, wherein mutually adjoining pixel groups arranged in a row or column, consisting of adjoining pixels of a row or column, are connected to adjoining control lines or data lines, as applicable, in alternation, some of the data lines being connected to a plurality of delay units such that only every other data line is connected to a particular delay unit of the delay units and each of remaining control lines is not connected to any delay unit, the delay units being used to store column voltage values for the data lines connected to the delay units until a clock signal is supplied to the delay units.
9. A display device as claimed in claim 8 , wherein the delay units are D-flip-flops.
10. A display device as claimed in claim 8 , characterized in that a pixel group comprises one pixel.
11. A display device as claimed in claim 8 , characterized in that mutually adjoining pixels of a column are connected to the adjoining data lines in alternation.
12. A display device as claimed in claim 8 , characterized in that the pixels comprise switching elements with control terminals which are connected to the control lines and data terminals which are connected to the data lines.
13. A display device as claimed in claim 8 , characterized in that the rows and columns situated at the edges of the display device are covered.
14. A method of controlling a display device as claimed in claim 8 .
