- 15 - ? test point :center point of the display area 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 c t = ?????? 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.(note that it may take several iterations of adjusting background level and box levels to determine the proper value for the background .next display the box levels to determine the proper value for the background level. look for shadowing in any direction from box e. independently vary the gray level (or color) of the background and box e until the worst case shadowing is observed. this defines the background (gbkg) and foreground (gfg) levels to be maintained for the remainder of the test. ? one point only (the target) will be measured. to determine that point proceed as follows using the background and foreground gray levels of step1 (gbkg and gfg). turn on each box at a time. look for the case with the worst shadowing. the box causing the worst case is the shadowing source, or bsrc. use bsrc and the box opposite from it that lies directly in the shadow path. that is the target box, or btgt. note that box eight be either bsrc or btgt, depending on the shadowing conditions, but typically bsrc and btgt will be a pair of www.datasheet.co.kr datasheet pdf - http://www..net/
- 16 - opposite boxes, a&c or b&d. btgt will only be displayed for aligning the lmd. it will be turned off for the actual measurement. ? the target box point (btgt) will be measured with the source box (bsrc) turned on then off. (btgt is for alignment purpose only) display the background only at level gbkg. display btgt determined in step 2 above. using the correct distance, angle, and measurement aperture, align the lmd to the center of the btgt. turn off btgt. with gbkg set to its proper level, measure the luminance (or color). next,turn on the source box bsrc. again measure at the center point of btgt (without btgt present.). in this case the lmd will be measuring the shadowing level, lsh. panel relative humidity jp777-e02 input signals video input ? type analog r, g, b. ? input impedance 75 ohm +/- 2 % ? polarity positive ? amplitude 0 - 0.7 +/- 0.05 vp ? display color same as lcd panel sync input ? signal separate horizontal and vertical sync, or composite sync which are ttl compatible ? polarity positive and negative. www.datasheet.co.kr datasheet pdf - http://www..net/

- 44 - plug and play plug & play ddc2b feature this monitor is equipped with vesa ddc2b capabilities according to the vesa ddc standard. it allows the monitor to inform the host system of its identity and, depending on the level of ddc used, communicate additional information about its display capabilities. the communication channel is defined in two levels, ddc2b. the ddc2bis a bidirectional data channel based on the i 2 c protocol. the host can request edid information over the ddc2b channel. this monitor will appear to be non-functional if there is no video input signal. in order for this monitor to operate properly, there must be a video input signal. this monitor meets the green monitor standards as set by the video electronics standards association(vesa) and/or the united states environmental protection agency (epa) and the swedish confederation employees (nutek). this feature is designed to conserve electrical energy by reducing power consumption when there is no video-input signal present. when there is no video input signal this monitor, following a time-out period, will automatically switch to an off mode. this reduces the monitor?s internal power supply consumption. after the video input signal is restored, full power is restored and the display is automatically redrawn. the appearance is similar to a ?screen saver? feature except the display is completely off. the display is restored by pressing a key on the keyboard, or clicking the mouse. using the right power cord the accessory power cord for the northern american region is the wallet plug with nema 5-15 style and is ul listed and csa labeled. the voltage rating for the power cord shall be 125 volt ac. supplied with units intended for connection to power outlet of personal computer: please use a cord set consisting of a minimum no. 18 awg, type sjt or svt three conductors flexible cord. one end terminates with a grounding type attachment plug, rated 10a, 250v,cee-22 male configuration. the other end terminates with a molded-on type connector body, rated 10a, 250v, having standard cee-22 female configuration. please note that power supply card needs to use vde 0602, 0625, 0821 approval power cord in european counties. www.datasheet.co.kr datasheet pdf - http://www..net/
