2) or
Fig.1 Definition of viewing angle When installing the module, pay attention and handle carefully not to allow any undue stress such as twist
bend. Since the front polarizer is easily damaged. Please pay attention not to scratch on its face. It is recommended to use a transparent acrylic resin board or other type of protective panel on the surface of the LCD module to protect the polarizer, LCD panel, etc.. 4) If the surface of the LCD panel is required to be cleaned, wipe it swiftly with cotton or other soft cloth. If it is not still clear completely, blow on and wipe it. 5) Water droplets, etc. must be wiped off immediately since they may cause color changes, staining, etc., if it remained for a long time. 6) Since LCD is made of glass substrate, dropping the module or banging it against hard objects may cause cracking or fragmentation. 7) Since CMOS LSIs are equipped in this module, following countermeasures must be taken to avoid electrostatics charge. 3)

1. Operator Electrostatic shielding clothes shall be had because it is feared that the static electricity is electrified to human body in case that operator have a insulating garment. 2. Equipment There is a possibility that the static electricity is charged to equipment which have a function of peeling or mechanism of friction(EX: Conveyer, soldering iron, working table), so the countermeasure countermeasure(electrostaticearth:1x108) should be made. 3. Floor Floor is a important part to leak static electricity which is generated from human body or equipment. There is a possibility that the static electricity is charged to them without leakage in case of insulating floor, so the countermeasure(electrostatic earth:1x108) should be made. 4.Humidity Humidity of working room may lower electrostatics generating material's resistance and have something to prevent electrifying. So, humidity should be kept over 50% because humidity less than 50 % may increase material's electrostatic earth resistance and it become easy to electrify. 5. Transportation/storage The measure should be made for storage materials because there is a possibility that the static electricity, which electrify to human body or storage materials like container by friction or peeling, cause the dielectric charge. 6. Others The laminator is attached on the surface of LCD module to prevent from scratches, fouling and dust. It should be peeled off unhurriedly with using static eliminator. And also, static eliminator should be installed to prevent LCD module from electrifying at assembling line. 8) Don't use any materials which emit gas from epoxy resin(amines' hardener) and silicon adhesive agent(dealcohol or deoxym) to prevent change polorizer color owing to gas. 9) Since leakage current, which may be caused by routing of CCFT cables, etc., may affect the brightness of display, the inverter has to be designed taking the leakage current into consideration. Thorough evaluation of the LCD module/inverter built into its host equipment shall be conducted, therefore, to ensure the specified brightness. 10) Avoid to expose the module to the direct sun-light, strong ultraviolet light, etc. for a long time. 11) If stored at temperatures under specified storage temperature, the LC may freeze and be deteriorated. If storage temperature exceed the specified rating, the molecular orientation of the LC may change to that of a liquid, and they may not revert to their original state. Therefore, the module should be always stored at normal room temperature. 12) Disassembling the LCD module can cause permanent damage and should be strictly avoided.

13) Procedure insert mating connector When the mating connector is inserted, it should be parallel to the used connector of LCD module and it should be inserted horizontally. When the mating connector is attempted to be fixed to LCD connector, it should be inserted properly in order not to create a gap as shown "A". Please insert the connector as both edge is placed to the connect position of LCD connector.

14) This specification describes display quality in case of no gray scale. Since display quality can be affected by gray scale methods, display quality shall be carefully evaluated for the usability of LCD module in case gray scale is displayed on the LCD module. 15) The module should be driven according to the specified ratings to avoid permanent damage. DC voltage drive leads to rapid deterioration of LC, so ensure that the drive is alternating waveform by continuous application of the signal M. Especially the power ON/OFF sequence shown on Page 24 should be kept to avoid latch-up of drive LSIs and application of DC voltage to LCD panel.

When LCD module is operated by high speed of XCK(Shift clock), (tCK - tWCKH -tWCKL) /2 is maximum. LCD module functions at the minimum frame cycle of 8.33 ms(Maximum frame frequency of 120 Hz). Owing to the characteristics of LCD module, "shadowing" will become more eminent as frame frequency goes up, while flicker will be reduced. According to our experiments, frame cycle of 8.33 ms Min. or frame frequency of 120 Hz Max. will demonstrate optimum display quality in terms of flicker and "shadowing". But since judgment of display quality is subjective and display quality such as "shadowing" is pattern dependent, it is recommended that decision of frame frequency, to which power consumption of the LCD module is proportional, be made based on your own through testing on the LCD module with every possible patterns displayed on it The intervals of one LP fall and next must be always the same, and LPs must be input continuously. The intervals must be 70s Max.

6. Module Driving Method 6-1. Circuit configuration Fig.12 shows the block diagram of the module's circuitry. 6-2. Display face configuration The display consists of 640x3(R,G,B)x240 dots as shown in Fig. 4. The interface is single panel with double drive to be driven at 1/244duty ratio. 6-3. Input data and control signal The LCD driver is 240 bits LSI, consisting of shift registers, latch circuits and LCD driver circuits. Input data for each row 640x3 (R,G,B) will be sequentially transferred in the form of 8 bit parallel data through shift registers from top left of the display together with clock signal (XCK). When input of one row 640x3 (R,G,B) is completed, the data will be latched in the form of parallel data corresponding to the signal electrodes by the falling edge of latch signal (LP) then, the corresponding drive signals will be transmitted to the 640x3 lines of column electrodes of the LCD panel by the LCD drive circuits. At this time, scan start-up signal (YD) has been transferred from the scan signal driver to the 1st row of scan electrodes, and the contents of the data signals are displayed on the 1st row of the display face according to the combinations of voltages applied to the scan and signal electrodes of the LCD. While the data of 1st row are being displayed, the data of 2nd row are entered. When data for 640x3 dots have been transferred, they will be latched by the falling edge of LP, switching the display to the 2nd row. Such data input will be repeated up to the 244th row of each display segment, from upper row to lower rows, to complete one frame of display by time sharing method. Then data input proceeds to the next display frame. YD generates scan signal to drive horizontal electrodes. Since DC voltage, if applied to LCD panel, causes chemical reaction in LC materials, causing deterioration of the materials, drive wave-form shall be inverted at every display frame to prevent the generation of such DC voltage. Control signal M plays such a role. Because of the characteristics of the CMOS driver LSI, the power consumption of the display module goes up with the clock frequency of XCK. To minimize data transfer speed of XCK clock the LSI has the system of transferring 8 bit parallel data through the 8 lines of shift registers. Thanks to this system the power consumption of the display module is minimized. In this circuit configuration, 8 bit display data shall input to data input pins of D0-7 . Furthermore, the display module has bus line system for data input to minimize the power consumption with data input terminals of each driver LSI being activated only when relevant data input is fed. Data input for column electrodes and chip select of driver LSI are made as follows:

The driver LSI at the left end of the display face is first selected, and the adjacent driver LSI right next side is selected when data of 240 dot (30XCK) is fed. This process is sequentially continued until data is fed to the driver LSI at the right end of the display face. This process is followed simultaneously both at the top and bottom column drivers LSI's. Thus data input will be made through 8 bit bus line sequentially from the left end of the display face. Since this display module contains no refresh RAM, it requires the above data and timing pulse inputs even for static display. The timing chart of input signals are shown in fig. 6 and Table 8.
