Abstract
The present disclosure relates to electronic displays and display components, specifically to a method of addressing more pixels with a smaller number of driver outputs while also allowing very narrow frames on three sides of a display. It further discloses a display driver integrated circuit capable of providing the signals required for the disclosed addressing method and display systems capable of being addressed by the disclosed method and display driver integrated circuit.
Claims20
1- A method of addressing an electronic display with a display driver integrated circuit, the method comprising:
- providing a display driver integrated circuit comprising a plurality of driver outputs;
- providing an electronic display comprising:
- an image area comprising:
- a plurality of pixels;
- a plurality of electrodes;
- and
- wherein the plurality of electrodes is connected to the plurality of pixels and the plurality of driver outputs;
- applying a common signal to one of the plurality of electrodes using one of the plurality of driver outputs while applying a data signal to each one of the other plurality of electrodes using one or more of the remaining plurality of driver outputs;
- and
- re-applying the common signal to one of the plurality of electrodes using one of the plurality of driver outputs until each one of the plurality of pixels of the image area have been addressed, wherein the common signal is applied at least once per update of the image area.
2- The method of claim 1 wherein the plurality of electrodes is a plurality of diagonally arranged electrodes.
3- The method of claim 1, wherein the electronic display is a passive matrix display.
4- The method of claim 1 wherein the electronic display is an active matrix display.
5- The method of claim 1 wherein the electronic display is a zenithal bi-stable display.
6- The method of claim 1 wherein the electronic display is an electrophoretic display.
7- An electronic display driver integrated circuit for addressing an electronic display comprising:
- a plurality of outputs, wherein each one of the plurality of outputs is capable of providing a scanning signal or data signal within each frame of addressing an image area of an electronic display;
- wherein each one of the plurality of outputs driving the image area provides the scanning signal at least once per frame;
- and
- wherein each one of the plurality of outputs not driving the image area provides the data signal.
8- The electronic display driver integrated circuit of claim 7 wherein each one of the plurality of outputs is capable of providing a third signal, wherein the third signal is an image independent fixed signal or a high impedance signal.
9- The electronic display driver integrated circuit of claim 7 further comprising a translation function from cartesian pixel coordinates to display dependent output numbers.
10- The electronic display driver integrated circuit of claim 7, wherein a selection of the third signal is based on an external stimulus.
11- The electronic display driver integrated circuit of claim 10, wherein the external stimulus is an environmental parameter.
12- An electronic display system comprising:
- an electronic display comprising:
- a plurality of pixels;
- a plurality of diagonally arranged electrodes;
- and
- wherein the plurality of pixels is connected by the plurality of diagonally arranged electrodes;
- an electronic display driver integrated circuit comprising:
- a plurality of outputs, wherein each one of the plurality of outputs is capable of providing a scanning signal or data signal within each frame of addressing an image area of the electronic display;
- wherein the plurality of diagonally arranged electrodes is connected to the plurality of driver outputs;
- and
- wherein each one of the plurality of outputs driving the image area provides the scanning signal at least once per frame, and each one of the plurality of outputs not driving the image area provides the data signal.
13- The electronic display system of claim 12, wherein the electronic display is a passive matrix display.
14- The electronic display system of claim 12, wherein the electronic display is an active matrix display.
15- The electronic display system of claim 12, wherein the electronic display is an emissive display.
16- The electronic display system of claim 12, wherein the electronic display is a transmissive display.
17- The electronic display system of claim 12, wherein the electronic display is a partially reflective display.
18- The electronic display system of claim 12, wherein the electronic display is an electrophoretic display.
19- The electronic display system of claim 12, wherein the electronic display is a liquid crystal display.
20- The electronic display system of claim 19, wherein the liquid crystal display is a zenithal bistable display.
