"vs" and "vblh" are the voltage value between low voltage side (cold) and high voltage side (hot). note3: the asymmetric ratio of working waveform for lamps (power supply voltage peak ratio, power supply current peak ratio and waveform space ratio) should be less than 5 % (see the following figure.). if the waveform is asymmetric, dc (d irect current) element apply into the lamp. in this case, a lamp lifetime may be shortened, because a distribution of a lamp enclosure substance inclines toward one side between low voltage terminal (cold terminal) and high voltage terminal (hot terminal). when designing the backlight inverter, evaluate asymmetric of lamp working waveform sufficiently. note4: this product consists of 2 lamps. 2 lamps are contained in the 1 lamp holder, and both lamps are connected to 1 low voltage cable. recommended lamp current is 5.0marms typical for each lamp, and sum of 2 lamps is 10marms typical . the lamp current should be measured by high-frequency current meter at the low voltage terminal. note5: the inverter should be designed so that the lamp starting voltage can be maintained for more than 1 second. otherwise the lamp may not be turned on. note6: in case "fo" is not the recommended value, beat noise may display on the screen, because of interference between "fo" and "1/th". recommended value of "fo" is as following th: horizontal cycle (see " 4.9.2 timing characteristics ".) n: natural number (1, 2, 3 ???????? ) note7: method of lamp cable installation may invite fluctuation of lamp current and voltage or asymmetric of lamp working waveform. when designing method of lamp cable installation, evaluate the fluctuation of lamp current, voltage and working waveform sufficiently. fo = (2n-1) 1 th 1 4 pa pb sa sb 0 | pa - pb | pb 100 5 % 100 5 % | sa - sb | sb www.datasheet.co.kr datasheet pdf - http://www..net/

(shock: to be not greater 539m/s 2 and to be not greater 11ms, pressure: to be not greater 19.6 n ( 16mm jig)) 6.3 attentions ! 6.3.1 handling of the product take hold of both ends without touching the circuit board when the product (lcd module) is picked up from inner packing box to avoid broken down or misadjustment, because of stress to mounting parts on the circuit board. do not hook nor pull cables such as lamp cable, and so on, in order to avoid any damage. when the product is put on the table temporar ily, display surface must be placed downward. when handling the product, take the measures of electrostatic discharge with such as earth band, ionic shower and so on, because the product may be damaged by electrostatic. the torque for product mounting screws must never exceed 0.294n ? m. higher torque might result in distortion of the bezel. the product must be installed using mounting holes without undue stress such as bends or twist (see outline drawings). and do not add undue stress to any portion (such as bezel flat area). bends or twist described above and undue stress to any portion except mounting hole portion may cause display mura. do not press or rub on the sensitive product surfa ce. when cleaning the product surface, use of the cloth with ethanolic liquid such as screen cleaner for lcd is recommended. do not push nor pull the interface connec tors while the product is working. do not bend or unbend the lamp cable at the near part of the lamp holding rubber, to avoid the damage for high voltage side of the lamp. if the lamp cable is attached on the metal part of the product directly, high frequency leak current to the metal part may occur, then the brightness ma y decrease or the lamp may not be turned on. www.datasheet.co.kr datasheet pdf - http://www..net/
NL10276BC20-08 data sheet dod-md-0097(1st edition) 24 ? when not connecting fg of the lcd module to the customer's equipment ground, inverter noise may create video noise on the lcd screen. ? when handling the product, use of an original protection sheet on the product surface (polarizer) is recommended for protection of product surface. adhesi ve type protection sheet may change color or characteristics of the polarizer. 6.3.2 environment do not operate or store in high temperature, high humidity, dewdrop atmosphere or corrosive gases. keep the product in packing box with antistatic pouch in room temperature to avoid dusts and sunlight, when storing the product. in order to prevent dew condensation occurring by temperature difference, the product packing box should be opened after enough time being left under the environment of an unpacking room. evaluate the leaving time sufficiently because a situation of dew condensation occurring is changed by the environmental temperature and humidity. (r ecommended leaving time: 6 hours or more with packing state) do not operate in high magnetic field. circuit boards may be broken down by it. this product is not designed as radiation hardened. 6.3.3 characteristics the following items are ne ither defects nor failures. response time, luminance and color may be changed by ambient temperature. display mura, flicker, vertical seam or small spot may be observed depending on display patterns. optical characteristics (e.g. luminance, display uniformity, etc.) gradually is going to change depending on operating time, and especially low te mperature, because the lcd has cold cathode fluorescent lamps. do not display the fixed pattern for a long time because it may cause image sticking. use a screen saver, if the fixed pattern is displayed on the screen. the display color may be changed depending on viewing angle because of the use of condenser sheet in the backlight. optical characteristics may be changed depending on input signal timings. the interference noise between input signal frequency for this product's signal processing board and luminance control frequency of the inverter may appear on a display. set up luminance control frequency of the inverter so that th e interference noise does not appear. 6.3.4 other all gnd and vcc terminals should be used without any non- connected lines. do not disassemble a product or adjust variable resistors. pack the product with original shipping package, in order to avoid any damages during transportation, when returning the product to nec for repair and so on. www.datasheet.co.kr datasheet pdf - http://www..net/
