Abstract

Methods and systems are provided for presenting content comprising a plurality of frames using display panel comprising an array of display elements. A method comprises transferring image data for a first frame of the plurality of frames to a display element at the beginning of a first frame interval and activating an illumination assembly after transferring image data for the first frame to the display element to present the first frame. The method further comprises transferring image data for a second frame to an energy storage element corresponding to the display element during the first frame interval, and deactivating the illumination assembly prior to transferring the image data for the second frame from the energy storage element to the display element.

First claim

What is claimed is:

1. A method of presenting content comprising a plurality of frames on a display panel comprising a plurality of drive circuits and a plurality of display elements coupled to a first node configured to receive a bias voltage, wherein each drive circuit includes a first energy storage element coupled between a second node and a ground reference node, a second energy storage element coupled between a third node and the ground reference node, and a fourth node coupled to a respective display element of the plurality of display elements, the respective display element being coupled between the first node and the fourth node of the respective drive circuit, the method comprising:
transferring all image data for a first frame of the plurality of frames at the beginning of a first frame interval by transferring respective image data for the first frame to each respective display element of the plurality of display elements from the second node coupled to the first energy storage element of each respective pixel drive circuit to the fourth node of the respective pixel drive circuit coupled to the respective display element at the beginning of the first frame interval;
activating an illumination assembly after the transferring of all of the image data for the first frame to the plurality of display elements to present the first frame;
activating a first lens configured to be aligned with a first eye of a prospective viewer during the first frame interval after the transferring of all of the image data for the first frame to the plurality of display elements, wherein the first frame corresponds to the first eye;
transferring, for each respective display element of the plurality of display elements, image data for a second frame of the plurality of frames to the third node coupled to the second energy storage element of the respective pixel drive circuit corresponding to the respective display element during the first frame interval;
deactivating the illumination assembly prior to transferring the image data for the second frame to each respective display element of the plurality of display elements at the beginning of a second frame interval from the third node coupled to the second energy storage element of the respective pixel drive circuit to the fourth node of the respective pixel drive circuit coupled to the respective display element; and
deactivating the first lens prior to transferring the image data for the second frame to the plurality of display elements.

2. The method of claim 1 , further comprising:
transferring the image data for the second frame to each respective display element of the plurality of display elements from the third node coupled to the second energy storage element of the respective pixel drive circuit to the fourth node of the respective pixel drive circuit coupled to the respective display element at the beginning of the second frame interval, the second frame interval being subsequent the first frame interval; and
after transferring image data for the second frame to the plurality of display elements:
activating the illumination assembly; and
activating a second lens configured to be aligned with a second eye of the prospective viewer.

3. The method of claim 2 , further comprising:
deactivating the illumination assembly prior to transferring image data for a third frame to the plurality of display elements, the third frame being subsequent the second frame; and
deactivating the second lens prior to transferring image data for the third frame to the plurality of display elements.

4. The method of claim 1 , the first energy storage element comprising a first capacitor and the second energy storage element comprising a second capacitor, wherein:
transferring the image data for the first frame comprises activating a first transistor coupled between the fourth node and the second node to transfer a first voltage from the first capacitor to a respective display element; and
transferring the image data for the second frame to the second energy storage element comprises activating a second transistor coupled between the third node and a fifth node to transfer a second voltage to the second capacitor.

5. The method of claim 4 , wherein:
transferring the image data for the first frame further comprises deactivating a third transistor coupled between the fourth node and the third node; and
transferring the image data for the second frame to the second energy storage element further comprises deactivating a fourth transistor coupled between the fifth node and the second node.

6. The method of claim 1 , the backlight including a plurality of illumination elements, wherein activating the illumination assembly comprises:
identifying a set of one or more illumination elements of the illumination assembly configured to direct light through the display element towards an eye location for the first eye corresponding to the first frame; and
activating the set of one or more illumination elements to direct light through the display element.

7. The method of claim 1 , further comprising:
transferring all of the image data for the second frame at the beginning of the second frame interval to the plurality of display elements by transferring respective image data for the second frame from the third node coupled to the second energy storage element of each respective pixel drive circuit to the fourth node of each respective pixel drive circuit coupled to each respective display element at the beginning of the second frame interval, the second frame interval being subsequent the first frame interval; and
after the transferring of all of the image data for the second frame to the plurality of display elements:
activating the illumination assembly; and
activating a second lens configured to be aligned with a second eye of the prospective viewer.

8. A display system for presenting content comprising a plurality of frames to a viewer, the display system comprising:
an illumination assembly;
a display panel comprising:
a plurality of display elements coupled to a first node configured to receive a bias voltage; and
a plurality of drive circuits, wherein each drive circuit includes:
a first energy storage element coupled between a second node and a ground reference node;
a second energy storage element coupled between a third node and the ground reference node; and
a fourth node coupled to a respective display element of the plurality of display elements, the respective display element being coupled between the first node and the fourth node of the respective drive circuit; and

a control module coupled to the illumination assembly and the display panel, wherein the control module is configured to:
transfer all image data corresponding to a first frame of the plurality of frames to the plurality of display elements at the beginning of a first frame interval by transferring, for each respective display element of the plurality of display elements, image data corresponding to the first frame from the second node to the fourth node at the beginning of the first frame interval;
store image data corresponding to a second frame for each display element of the plurality of display elements during the first frame interval, the image data for each display element being stored by the respective second energy storage element corresponding to the respective display element;
activate the illumination assembly to direct light towards the display panel after transferring the image data for the first frame to the plurality of display elements; and
deactivate the illumination assembly prior to transferring the stored image data for the second frame to the plurality of display elements at the beginning of a second frame inte
