Display control system for micromirror device

Abstract

This invention provides a display control system that includes: a) a micromirror array comprising a plurality of mirrors; b) a first control function for controlling the mirrors in a first state; c) a second control function for controlling the mirrors in a second state; d) and a switchover controller for switching from the first state to second state, or from the second state to first state, wherein the switchover controller switches the state of at least two mirrors simultaneously at a same predetermined point within a frame period.

Description

technical field [0001] The present invention relates to image display systems and, more particularly, to display systems having specially arranged and controlled spatial light modulators or light sources. Background technique [0002] Even though significant advances have been made in recent years in realizing electromechanical micromirror devices as spatial light modulators, there are still limitations and difficulties in adopting them to provide high-quality image displays. In particular, as display systems in the HDTV format become popular, the size of images on the screen becomes larger, such as a diagonal size of 100" or more. When the specification is a 100"-size image including 1920×1080 pixels , the pixel size on the screen is larger than 1mm. Similarly, in 50"-size images and XGA pixels, the pixel size is 1mm. The observer can see every pixel on the screen. For this, the display system requires a large number of gray levels greater than 10 or 16 bits, In order to ...

Problems solved by technology

Specifically, the application of conventional configurations of control circuits faces the following limitations: the gray scale (PWM between on and off states) of conventional systems is limited by LSB (i.e., least significant bit, or minimum pulse width)

However, these inventions do not address or provide a direct solution for those of ordinary skill in the art to overcome the above-mentioned limitations and difficulties.
