Please pay attention not to scratch on its face. It is recommended to use a transparent acrylic resin board or other type of protective the LCD module to protect the polarizer, 4) blow on and wipe it. Water droplets, etc. must be wiped off immediately remained 6) LCD panel, etc.. 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, 5) panel on the surface of etc., for a long time. Since LCD is made of glass substrate, dropping cracking since they may cause color changes, staining, or fragmentation. the module or banging it against hard objects may cause if it SPEC MODEL No. LC99404 SHARP 7) No. Since CMOS LSIs are equipped in this module, electrostatics PAGE 2 LM7MS623 following countermeasures must be taken to avoid charge. l-Operator Electrostatic shielding clothes shall be had because it is feared that the static electricity human body in case that operator have a insulating is electrified to garment. 2.Equipmeot There is a possibility mechanism that the static electricity of friction(EX: is charged to equipment Conveyer, soldering which have a function of peeling or iron, working table), so the countermeasure(electrostatic earth:1 X lo8 Q) 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: 1 X 10’ Q ) should be made. 4.Humidity Humidity of working room may lower electrostatics prevent electrifying. material’s So, humidity electrostatic generating material’s resistance and have something should be kept over 50% because humidity to less than 50 % may increase earth resistance and it become easy to electrify. S.Transportation/storage The measure should be made for storage materials because there is a possibility that the static electriicity, which electrify to human body or storage materials like container by friction or peeling, cause the dielectric charge. 6.0thers The laminator is attached on the surface of LCD module to prevent from scratches, fouling and dust.

The interface is single panel with single drive to be driven at l/240 duty ratio. 6-3. ‘Lnput data and cqntrol signal The LCD driver is 160 bits LSI, consisting of shift registers, latch circuits and LCD driver circuits. Display data which are externally divided into data for each row (640 dots) will be sequentially transferred in the form of 4- bit parallel data through shift registers by Clock Signal CP2 from the left top of the display face. When input of one row (640 dots) is completed, the data will be latched in the form of parallel data for 640 lines of signal electrodes by latch signal (CPl) will be transmitted then, the corresponding drive signals to the 640 lines of column electrodes of the LCD panel by the LCD drive circuits. At this time, scan start-up signal (S) 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 rows of the display face according to the combinations of voltages applied to the scan and signal electrodes of the LCD. While the 1st rows of data are being displayed, the 2nd row of data are entered. When 640 dots of data have been transferred, they latched on the falling edge of CPl clock, the display face proceeds to the 2nd rows of display. Such data input will be repeated up to the 240th 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. Scan start -up signal S generates scan signal to drive horizontal electrodes. Since DC voltage, if applied to LCD panel, causes chemical reaction which will deteriorate drive wave-form shall be inverted at every display frame to prevent the generation Control signal M plays such a role. LCD panel. of such DC voltage. SPEC No. MODEL LC99404 SHARP Because of the characteristics No. PAGE 15 Livl7MS623 of the CMOS driver LSI, the power consumption of the display module goes up as the operating frequency CP2. Thanks to the 4 lines of shift registers to reduce the data transfer speed CP2 Thanks to the LSI, the power consumption In this circuit configuration, Furthermore, of the display module will be minimized. 4-bit display data shalI be therefore input to data input pins of DO -3. the display module has bus line system for data input to minimize data input termin& the power consumption with 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 of the right next side is selected when data of 160 dot (4OCP2) is fed. This process is sequentially continued until data is fed to the driver LSI at the right end of the display face. Thus data input will be made through 4-bit bus line sequentially Since this display module contains no refresh RAM, from the left end of the display face. it requires the above data and timing static display.
