Abstract: A phase calibration method includes: producing a synchronization signal; controlling switches of a light source based on a time series; measuring a first light intensity of the light passing through a phosphor wheel and a color wheel; changing phases of the phosphor wheel or the color wheel; measuring a second light intensity of the light passing through the phosphor wheel and the color wheel; changing the phases of the phosphor wheel or the color wheel again; measuring a third light intensity of the light passing through the phosphor wheel and the color wheel; repeating changing the phases if the second light intensity is greater than the first light intensity, and the third light intensity is greater than the second light intensity; or when the second light intensity is smaller than the first light intensity, and the third light intensity is greater than the first light intensity.

Abstract: A display device and a method for starting up at a low temperature utilizing a heating unit of the display device or an external heating unit to increase the environmental temperature of the display device are disclosed. After the environmental temperature inside the display device reaches a starting-up temperature, the display device can be started up in the low-temperature environment.

Abstract: A display apparatus adapted for a display wall, an image adjustment method therefor and a display wall therewith are provided. The image between display apparatuses of the display wall is not exactly displayed, especially for adjacent areas between every two neighbored display apparatuses, and the displayed image is required to be adjusted for the defects. The image adjustment method includes receiving a video signal and then setting an initial image capture area in a scaler of each of display apparatuses in the display wall for selecting and scaling a part of the video image and transmitting the part to a digital display element of the display apparatus for display. Then based on the whole image displayed on the display wall by combining the image displayed on each of the display apparatuses, sequentially adjusts the image displayed by each of the display apparatuses. While adjusting the size of the image, one side of an image capture area is fixed and the length of the image capture area is adjusted.

Abstract: A system, an apparatus and a method for configuring a display ID are provided. The system comprises a setting unit, a plurality of displays and a plurality of switches. Wherein, the displays are electrically coupled to the setting unit, and the switches are configured in between the setting unit and its corresponding display. Each of the switches corresponds to one of the displays, and is turned on or turned off by its corresponding display. When the setting unit issues a setting ID instruction, all of the switches is turned on by its corresponding display. Thereafter, the setting unit issues a plurality of identification configuration instructions. By sequentially turning off each of the switches, the ID of the corresponding display can be configured by each of the ID configuration instructions.
