(+24v of dc supply voltage) and in order to improve the response time of lcd, th is module applies the over s hoot driving (o/s driving) technology for the control circuit .in the o/s driving technology, signals are being applied to the liquid crystal according to a pre-fixed process as an image signal of th e present frame when a difference is found between image signal of the previous frame and that of the current frame after comparing them. by using the captioned process, the image signals of this lcd module are being set so that image response can be completed within one frame, as a result, image blur can be improved and clear image performance can be realized. 3. mechanical specifications parameter specifications unit 64.8 ?i diagonal ?j cm display size 25.5 ?i diagonal ?j inch active area 564.8 (h) x 317.6 (v) mm pixel format 1366 (h) x 768 (v) ?i 1pixel = r + g + b dot ?j pixel pixel pitch 0.4135(h) x 0.4135 (v) mm pixel configuration r, g, b vertical stripe display mode normally black unit outline dimensions (*1) 646.0(w) x 373.0(h) x 51.0(d) mm mass 6.4 ?} 0.3 kg surface treatment anti glare, low reflection coating hard coating: 2h haze: 23 +/- 5% (*1) outline dimensions are shown in fig.1 www..net www..net

(a ?` e) 10. handling precautions of the module a) be sure to turn off the power supply when inserting or disconnecting the cable. b) this product is using the parts (inverter, ccft etc), which generate the high voltage. therefore, during operating, please don't touch these parts. c) brightness control voltage is switched for ?on? and ?off?, as shown in fig.4. voltage difference generated by this switching, ? v inv, may affect a sound output, etc. when the power supply is shared between the inverter and its surrounding circuit. so, separate the power supply of the inverter circuit with the one of its surrounding circuit. on on off ? v inv 0v 0a 0v v inv i inv pwm control signal fig.4 brightness control voltage. *since inverter board?s gnd is not connected to the frame of the lcd module, please connect it with the customer?s gnd of inverter power supply. d) be sure to design the cabinet so that the module can be installed without any extra stress such as warp or twist. e) since the front polarizer is easily damaged, pay attention not to scratch it. f) since long contact with water may cause discoloration or spots, wipe off water drop immediately. g) when the panel surface is soiled, wipe it with absorbent cotton or other soft cloth. h) since the panel is made of glass, it may break or cr ack if dropped or bumped on hard surface. handle with care. a b c d e 192 384 576 pixel pixel 342 683 1024 maximum luminance of five points (brightness ) ?a ?v ?? minimum luminance of five points (brightness) www..net www..net
ld- 17214-18 i) since cmos lsi is used in this module, take care of static electricity and take the human earth into consideration when handling. j) the module has some printed circuit boards (pcbs) on the back side, take care to keep them form any stress or pressure when handling or installing the module; otherwise some of electronic parts on the pcbs may be damaged. k) observe all other precautionary requirements in handling components. l) when some pressure is added onto the module from rear side constantly, it causes display non-uniformity issue, functional defect, etc.. so, please avoid such design. m) when giving a touch to the panel at power on supply, it may cause some kinds of degradation. in that case, once turn off the power supply, and turn on after several seconds again, and that is disappear. n) when handling lcd modules and assembling them into cabinets, please be noted that long-term storage in the environment of oxidization or deoxidization gas and the use of such materials as reagent, solvent, adhesive, resin, etc. which generate these gasses, may cause corrosion and discoloration of the lcd modules. www..net www..net
