Abstract
Displays using a low cost method to implement switching element point inversion driving schemes while using integrated circuits that are designed to implement switching element row inversion or switching element column driving schemes are described. In one display, a first color dot is on a first side of a control line and a second color dot is on a second side of the control line. A first switching element is coupled to the first control line and the first color dot and a second switching element is coupled to the second color dot and the control line. Thus the control line controls color dots on two different rows or two different columns.
Claims19
A display comprising:
- a first control line;
- a first color dot on a first side of the control line;
- a second color dot on a second side of the control line;
- a first switching element coupled to the first control line and the first color dot;
- wherein the first switching element controls the first color dot;
- a second switching element coupled to the first control line and the second color dot;
- wherein the second switching element controls the second color dot;
- a second control line;
- a third color dot;
- wherein the first color dot and the third color dot are in a first row of color dots;
- a third switching element coupled to the third color dot and the second control line;
- a third control line coupled to the first switching element;
- a fourth control line coupled to the second switching element and the third switching element;
- and
- a data control system, wherein the data control system is configured to provide source data on the third control line and delayed source data on the fourth control line.
A display comprising:
- a liquid crystal unit;
- a data control system, wherein the data control system is configured to provide source data and delayed source data to the liquid crystal unit.
