AC to DC Converter Requirements
Input Voltage Range | The operating range shall be from 90 to 132 and 195 to 265 AVC | |
sinusoidal for all models specified. | ||
| ||
|
| |
Input Frequency Range | Input power frequency range sha;; be from 47.5 to 63 Hz over the | |
specified input voltage range. | ||
| ||
|
| |
| Power consumption for the monitor shall be less than 46W over the | |
Power Consumption | specified voltage and frequency ranges. In suspend or sleep mode | |
| the power consumption will be less than 2W. | |
|
| |
Line Fuse | The AC input shall be fused and become electrically open as a result | |
on an unsafe current level. The fuse many not be user replaceable. | ||
| ||
|
| |
| The power supply shall start and function properly when under full | |
Initial Cold Start | load, with worst case conditions of input voltage, input frequenct, | |
| operating temperature, and cold backlight lamps. | |
|
| |
| The inrush current must be limited to 30A when operated at | |
Inrush Current | 120VAC, and 50A when operated at 220VAC. Inrush current is | |
measured at an ambient temperature of 25oC, with the unit | ||
| temperature stabilized in the | |
|
| |
| The power supply shall be damaged when switched ON for one | |
Hot Start Cycle | second and OFF for one second for seven consecutive after | |
operating for one hour at full load, 25oC, and nominal input line | ||
| voltage. | |
| The power supply shall contain protection circuitry such that the | |
Under Voltage | application of an input voltage below the minimum specified in this | |
table shall not cause damage to the power supply unit nor cause | ||
| ||
| failure of the input. | |
|
| |
| The power supply shall operate within IEC | |
Line Transient | ||
| supply shall operate and comply with CE mark. | |

1.3.8Display Communications Channel
The monitor assembly shall provide a display communications channel that conforms to VESA DDC2Bi hardware requirements. This configuration shall contain the
1.3.9Firmware Update Function (same ISP function) The update firmware need through from the
1.4PANEL ELECTRICAL
1.4.1General Requirements
The panel used as the display device shall be an WUXGA resolution, 24W
1.4.2Panel Timings
The controller included with the monitor shall translate all video timings from the CPU that meet the timing requirements listed in Panel specification into timings appropriate for the panel. Under no circumstances may the controller supply the panel with timings that may result in damage. The controller shall insulate the panel from the CPU , so that the panel shall always be driven per it's own specification regardless of the timings being sent from the CPU.
1.4.3Polarizer Hardness
The outer face of the front polarizer panel shall be covered with a coating with a # 3 hardness value .
1.4.4Backlight Requirements
1.4.4.1General Requirements
The backlight assembly shall be designed to support field replacement at the customer site or authorized service center. The lamps shall have a continuous operating life of at least 40,000 hours at 25. The operating life is defined as having ended when the illumination of light has reached 50% of the initial value. The lamps shall extend a sufficient amount from the edge of the light guide that sputtering over the life of the lamps shall not cause degradation of the luminance uniformity (such as
1.4.4.2Lamps Startup Time
The backlight lamps shall start about 2 sec of the time the monitor power switch is pressed or the monitor is restarted from a power - down mode
.The starting time shall stay about 2 sec. for the
minimum expected life of the lamps. Test conditions are as follows : Ambient Light
Inactive Time
1.4.5Defects
1.4.5.1Visual Inspection
The LCD panel shall be inspected with all pixels set to white,black , red , green , and blue. The color variation, brightness variation , and overall appearance must not be perceived as poor quality by
