Optical characteristics are determined after the unit has been ‘ON’ and stable for approximately 45 minutes
in a dark environment at 25°C. The values specified are at an approximate distance 500 mm from the LCD
surface at a viewing angle of φand Өequal to 0°

Note：
1. Contrast Ratio (CR) is defined mathematically as:
2. Surface luminance is luminance value at point 5 across the LCD surface 50cm from the surface with all
pixels displaying white. From more information see FIG 2. LWH=Lon5 where Lon5 is the luminance with

12
all pixels displaying white at center 5 location.
3. The variation in surface luminance, _WHITE is defined (center of Screen) as:
δHITE(9P)= Minimum(Lon1, Lon2,…,Lon9)/ Maximum(Lon1, Lon2,…Lon9)
4. Response time Tr is the average time required for display transition by switching the input signal for five
luminance ratio (0%,25%,50%,75%,100% brightness matrix) and is based on Fv=60Hz to optimize.
The response time is defined as the following figure and shall be measured by switching the input
signal for
“any level of grey(bright) “ and “any level of gray(dark)”.
Any level of gray (Bright) Any level of gray (Dark) Any level of gray
(Bright)
FIG. 2 Luminance
5. Viewing angle is the angle at which the contrast ratio is greater than 10. The angles are
determined for the horizontal or x axis and the vertical or y axis with respect to the z axis which is
normal to the LCD surface. For more information see FIG3.

Scheduler
スケジューラー
1. User can set 7 secheuler to decide the power
on/off time, source, frequency.
2. User can set any time, date, source, frequency in
each schedule
3. If user select USB-photo or USB-music or
USB-movie in power on
source, it will follow playlist to play. If user didn't
create playlist, system
will depend on USB-photo or USB-music or
USB-move setting to auto
play the photo or music or move file in USB root.
4. Support power on source option : AV, Component,
HDMI1, HDMI2, DVD-D, VGA,USB-photo,
USB-music, USB-movie
5. schedule behavior
case 1: if the power on time is same in different
schedule, system will use smaller schedule setting to
power on. Smaller schedule number priority is
higher.
case 2: if the off time of current Schedule is equal to
the power on time of
next schedule, system will cancel current off time
and use next schedule
off time.
Signal Check Priority
信号チェック優先度
1. User can set signal priority 1~5. (priority 1 is
the highest)
2. If current source signal is lost, start failover
function(auto search signal according signal priority
setting). If higher priority source exist signal, start
failback function (auto switch to higher priority
source).

18
3. If user change source by input source OSD or
RS232/LAN command, source will keep at user
selected source(Don’t care Priority setting at this
time until user selected source signal is lost ). If user
selected source
signal is lost, PID will search the active input source
according to the
setting of Signal Priority Check. (even user select
source signal back,
source will not change back to user selected
source).
4. After start signal check priority function, if higher
priority signal exist,
auto switch to higher priority source. If all source no
signal, continue to
search active input source according to the setting of
signal priority check.
5. In search signal of signal prioritycheck setting, the
checking period is about 2 seconds each item. If
user change source manually, the check timeout is
10 seconds.
6. If user select USB-photo or USB-music or
USB-movie, it will follow playlist to play. If user didn't
create playlist, system will depend on USB-photo or
USB-music or USB-move setting to auto play the
photo or music or move file in USB root.
7. In media, if user press EXIT key to leave playing
mode, the auto play behavior will stop.
8. Support source option : AV/Component, HDMI1,
HDMI2, DVD-D, VGA, USB-photo, USB-music,
USB-movie
(only can set one of USB-photo, USB-music and
USB-movie)
9. if signal priority check = enable, Power on source
will search the active source according the setting of
signal priority check. if signal priority check =
disable, power on source will the last source.
10 if signal priority check =enable and power on

19
source is USB, system will auto play USB function.
11.This function(Failover/Failback) is premised on
working automatically basically.
Usually, the source used by a primary is set as P1.It
is a backup function
to when the signal of P1 is lost.
