(+24v of dc supply voltage) and in order to improve the response time of lcd, this lcd module applies the over shoot 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 the present frame when a difference is found between image signal of the previous frame and that of the current frame after comparing them. with this technology, image signals can be set so that liquid crystal response completes within one frame. as a result, motion blur reduces and clearer display performance can be realized. 3. mechanical specifications parameter specifications unit 116.8 (diagonal) cm display size 46.0 (diagonal) inch active area 1018.08(h) x 572.67 (v) mm pixel format 1920(h) x 1080(v) (1pixel = r + g + b dot) pixel pixel pitch 0.53025(h) x 0.53025 (v) mm pixel configuration r, g, b vertical stripe display mode normally black unit outline dimensions (*1) 1083.0(w) x 624.7(h) x 53.4(d) mm mass 11.5 1.0 kg surface treatment low haze anti glare haze value:8% hard coating: 3h (*1) outline dimensions are shown in fig.1 (excluding protruding portion) www.datasheet.co.kr datasheet pdf - http://www..net/

(a e) 9. 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 crac k if dropped or bumped on hard surface. handle with care. i) since cmos lsi is used in this lcd module, take care of static electricity and take the human earth into consideration when handling. j) this lcd 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 modul e; otherwise some of electronic parts on the pcbs may be damaged. k) observe all other precautionary requirements in handling components. a b c d e 270 540 810 pixel pixel 480 960 1440 maximum luminance of five points (brightness ) ?v ?? minimum luminance of five points (brightness) www.datasheet.co.kr datasheet pdf - http://www..net/
ld- k21505- 19 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. o) this lcd module is designed to prevent dust from entering into it. however, there would be a possibility to have a bad effect on display performance in case of having dust inside of lcd module. p) this lcd module pass over the rust. 10. packing form a) piling number of cartons : 2 maximum b) packing quantity in one carton : 8 pcs. c) carton size : 1190(w) 1160 (d) 870(h) [mm] d) total mass of one carton filled with full modules : 120 kg (typ.) paking form are shown in fig.5 11. reliability test item no. test item condition 1 high temperature storage test ta=60 o c 240h 2 low temperature storage test ta=-25 o c 240h 3 high temperature and high humidity operation test ta=40 o c 95%rh 240h (no condensation) 4 high temperature operation test ta=50 o c 240h 5 low temperature operation test ta=0 o c 240h 6 vibration test (non-operation) frequency : 10~57hz/vibration width (one side): 0.075mm : 58~500hz/acceleration: 9.8 m/s 2 sweep time: 11 minutes test period: 3 hours (1h for each direction of x, y, z) 7 shock test (non-operation) maximum acceleration: 294m/s 2 pulse width : 11ms, sinusoidal half wave direction: +/-x, +/-y, +/-z , once for each direction. 8 esd * at the following conditions, it is a thing without incorrect operation and destruction.
