Chapter 1 Monitor Feature INTRODUCTION Scope This specification defines the requirements for the 17” MICRO-PROCESSOR based Multi-mode supported high resolution color LCD monitor. This monitor can be directly connected to general 15 pin D-sub VGA connector and eliminates the requirement of optional special display card. It also supports VESA DPMS power management and plug & play function. There is a build-in stereo audio amplifier with volume control to drive a pair of speakers.
ELECTRICAL REQUIREMENTS Standard Test Conditions All tests shall be performed under the following conditions, unless otherwise specified. Ambient light : 225 lux Viewing distance : 50 cm in front of LCD panel Warrn up time All specifications : 30 minutes Fully functional : 5 seconds Measuring Equipment : Chroma 2250 signal generator or equivalent, directly Connected to the monitor under test.
LCD monitor General specification (AUO M170EG01(VD)) General specification - 10 -
Optical specifications - 11 -
Note 1) Definition of Viewing Angle: Viewing angle range (10≤CR) Note 2) Definition of Contrast Ratio (CR): Ratio of gray max(Gmax),gray min(Gmin) at the center point of panel.
Note 4) After stabilizing and leaving the panel alone at a given temperature for 30 min, the measurement should be executed .Measurement should be executed n a stable, windless ,and dark room.30 min after lighting the back-light. This should be measured in the center of screen. Dual lamp current :13.0mA(6.5mA x2)(Refer to the note(1) in the page 14 for more information ).
Notes 5) Definition of Luminance of White : measure the luminance of white at center point. Notes 6)Definition of 5 points brightness uniformity (Measuring points: Refer to the Note 5) Bmax BUNI= ⎯⎯⎯⎯⎯⎯⎯ Bmin Bmax: Maximum brightness Bmin: Minimum brightness Notes 7) Definition of Flicker level Flicker Voltage pp F = ⎯⎯⎯⎯⎯⎯⎯⎯⎯ x 100 % LMD Voltage dc ♦ One maximum value of three estimated values.
Note 8) Definition of Crosstalk (Refer to the VESA STD) The calculation for shadowing is made from the 2 luminance measurements Gbkg and Lsh, as follows: Lmax -Lmin CT = ⎯⎯⎯⎯⎯⎯ x100 % Lmin Where Lmax is the larger value of Gbkg or Lsh , and Lmin is the smaller of the two. ♦ To determine background and foreground levels (colors),first set the background to any gray scale or color level suitable for shadowing determination.
