  • Page 42: Color Irregularity Correction

    XG-V10WU XG-V10WE 4-5. Color irregularity correction [What is color irregularity?] The phenomenon that color reproduction differs depending on the points on the screen of three-panel LCD projec- tor. It is conspicuous especially when displaying all white, all black or all gray screen.
  • Page 43 XG-V10WU XG-V10WE [Principle of color irregularity correction] The color irregularity occurs when optical output against video signal input does not meet the expected value due to the above mentioned factors 1 to 4. For its correction, therefore, it works to apply the correction voltage on a line preceding the LCD panel so that the optical output against the signal input can meet the expected value.
  • Page 44 XG-V10WU XG-V10WE 2. Color irregularity correction data making tool (Application program for Windows) The color irregularity correction data making tool is similar to the above described color irregularity correction data making system but with its camera replaced by human eyes. With this tool, the operator will observe the screen with eyes, judge the state of color irregularity, and adjust the correction data with the tool so that the luminance on the screen becomes even.

  • Page 60: Simple Check Of Rs-232C Out Port

    XG-V10WU XG-V10WE 6-3. Simple check of RS-232C OUT port 1 Supply the return code (0x0D) to the port. 2 If “RETRY” or the returned code comes back in text, the port and the sub-microprocessor IC2601 are working. 6-4. Key entry detection The operation of the key (QSW-Z0524CEZZ) is detected by the sub-microprocessor IC2601 (IX3502CE).

  • Page 61: Detection Of Cooling Fan Rotation

    XG-V10WU XG-V10WE 6-7. Detection of cooling fan rotation Rotational speeds of the cooling fans used in the set are detected. Sequence of detection 1. Pulse signal sent out from each fan, which is variable with rotational speed, is supplied to IC7301 at its pins (6) (IC0), (5) (IC1), (4) (IC2), and (3) (IC3).
