Abstract
Architecture and designs of display devices are described, where the display devices possesses high spatial resolution as well as high intensity resolution and may be readily used in various display applications. According to one aspect of the present invention, a display device includes an array of image elements, each of the image elements further includes an array of sub-image elements. A portion of an image element area, namely some of the sub-image elements, is turned on, which has the same perceived brightness level of turning on an entire image element for a specific time. In addition, various designs of an image element or a sub-image element are described.
Claims16
A display device comprising:
- a plurality of image elements, each of the image elements including a set of sub-image elements arranged in rows and columns, each of the sub-image elements addressed by a control line and a data line, each of the image elements designed to produce brightness levels in an n-bit scale;
- and
- a driving circuit provided to drive the sub-image elements in accordance with a video signal to be displayed on the display device, the driving circuit designed to turn on some of the sub-image elements in each of the image elements to achieve perceived effect of having the each of the image elements turned on for a predefined time.
The display device as recited in claim 14, wherein the each of the sub-image elements achieves planar update by cascading the first and second cells to form one sub-image element, wherein the first cell stores an updated datum while the second cell stores an datum to control the metal plate.
