摘要:
A row (common electrode)-modulation gray-level LCD device and a method thereof, which use a row-modulation device to input at least two sequentially generated original common voltage signals to the common electrode of the same row, whereby the sequentially generated original common voltage signals cooperate with the segment voltage signals to generate voltage differences in the common electrode and turn on or turn off the same monochromatic pixel in a time-division mode. The accumulated effect of the time-division turn-on and turn-off states enables the same monochromatic pixel to present gray-pixel.

The present invention discloses a single-level driver is programmed to generate a plurality of segment voltage signals. A multicolor backlight modulation device receives the segment voltage signals and modulating a portion of the segment voltage signals to generate a common voltage signal and at least two synchronous color-separation backlight driving signals driving a backlight source to emitting different-color backlights. The common voltage signal cooperates with the segment voltage signals to form voltage differences which drive a mono-pixel to turn on or turn off in a time-division mode and allow different-color backlights to pass the mono-pixel at the same time. The time-division different-color backlights are accumulated by vision persistence to present a chromatic effect on the mono-pixel. The resultant colors can be intelligently varied via programming the segment voltage signals to achieve diversified multicolor effects. Therefore, the present invention can enable mono-pixels to present multicolor effect with a single-level display chip.

The present invention modulates a plurality of sequentially generated common voltage signals into a new common voltage signal and synchronous color-separation backlight control signals turning on different-color backlight sources. The new common voltage signals and segment voltage signals cooperate to form voltage differences making a mono-pixel allow different-color backlights to pass and controlling the mono-pixel to turn on or turn off in a time-division mode. The effects of the time-division different-color backlights are accumulated by vision persistence to form different colors on the mono-pixel. Thus, the present invention can enable a monochromatic LCD chip and a mono-pixel to present a multi-color effect.

An air conditioning apparatus includes a case body, and an air cooling coil disposed in the case body to cool an air stream flowing thereacross. A blower is disposed in the case body, and is driven by an output shaft of a motor to blow the air stream across the air cooling coil and deliver cooled air stream forwardly and outwardly of the case body. A drain pane is disposed under the air cooling coil to collect droplets of condensate, and has a first outlet to drain water therein. A water pump includes a pump body with an accommodation chamber, and an impeller received in the chamber and provided with a driven shaft. The driven shaft extends outwardly of the pump body to form a coupling end to be coupled with the output shaft so as to enable the motor to drive the impeller to rotate. The pump body has a second inlet in fluid communication with the first outlet of the drain pane, and a second outlet so that rotation of the impeller will generate a suction force to drain the water from the first outlet via the second inlet and out of the second outlet.
