摘要:
An embodiment of this invention relates to an intelligent lighting device that can receive signals and change the illumination conditions as a result of the received signals. The lighting device can change hue, saturation, and brightness as a response to received signals. One example of using such a lighting device is to display particular colors as a response to certain events. Among others, embodiments may include vehicle lighting systems, an information cube, a back lighting system for a display panel, and an indicator of a condition of a package.

A microelectromechanical (MEMS) device includes a substrate and a movable layer mechanically coupled to the substrate. The movable layer moves from a first position to a second position at a first rate and from the second position to the first position at a second rate faster than the first rate. The MEMS device further includes an adjustable cavity defined between the substrate and the movable layer and containing a fluid. The MEMS device further includes a fluid conductive element through which the fluid flows at a first flowrate from inside the cavity to outside the cavity upon movement of the movable layer from the second position to the first position and through which the fluid flows at a second flowrate slower than the first flowrate from outside the cavity to inside the cavity upon movement of the movable layer from the first position to the second position.

The present invention relates to a light emitting device where currents passing through scan lines have the same values. The light emitting device includes data lines, scan lines, pixels, one or more dummy data line and a cross-talk preventing circuit. The data lines are disposed in a first direction, and the scan lines are disposed in a second direction. The pixels are formed in cross areas of the data lines and the scan lines. The dummy data line is disposed in the first direction. The cross-talk preventing circuit provides a compensating current to scan line related to luminescence of the scan lines through the dummy data line so that total sum of current passing through the scan line has a desired value. In the light emitting device, currents passing through scan lines have the same values, and so a cross-talk phenomenon is not occurred to a panel.

摘要:
In a display device which includes a scanning circuit, an ON resistance of a non-selection switch of the scanning circuit is set larger than an ON resistance of a selection switch. By setting the ON resistance of the non-selection switch of the scanning circuit larger than the ON resistance of the selection switch, an element size of the non selection switch can be made small and hence, a chip size of a scanning driver which is formed of a semiconductor integrated circuit constituting a scanning circuit can be made small without adversely influencing the display characteristics of the display device.
