spec no. lcy-w06802 model no. LM057QC1T08 page 1 1) industrial(mechanical) design of the product in which th is lcd module will be incorporated must be made so that the viewing angle characteristics of the lcd may be optimized. this module?s viewing angle is illustrated in fig.1. y min. < viewing angle < y max. (for the specific values of y min., and y max., refer to the table ) please consider the optimum viewing conditions acco rding to the purpose when installing the module. fig.14 definition of viewing angle 2) this module should be in stalled using mounting holes of metal bezel. when installing the module, pay attention and handle carefully not to allow any undue stress such as twist or bend. 3) 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 boa rd 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 si nce 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. panel surface viewing direction + y y=0 (n ormal line) - y www.datasheet.co.kr datasheet pdf - http://www..net/

spec no. lcy-w06802 model no. LM057QC1T08 page 13 6. module driving method 6-1. input data and control signal the lcd driver is 240 bits lsi, consisting of shif t registers, latch circuits and lcd driver circuits. input data for each row (320 3 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 (320 3 r,g,b) is completed, the data will be latched in the form of parallel data corresponding to the signal electrodes by the fa lling edge of latch signal (lp) then, the corresponding drive signals will be transmitted to the 320 3 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 a nd signal electrodes of the lcd. while the data of 1st row are being displayed, the data of 2nd row are entered. when data for 320 3 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 240th row of each display segment, from upper row to lower rows, to complete one frame of display by time sharing method. simultaneously the same scanning sequence occur at the lower panel. then data i nput proceeds to the next display frame. yd generates scan signal to drive horizontal electrodes. since dc voltage, if applied to lcd panel, cau ses chemical reaction in lc materials, causing deterioration of the materials, drive wave-form shall be inverted at ev ery display frame to prevent the generation of such dc voltage. control signal m plays such a role. because of the characteristics of the cmos dr iver lsi, the power consumption of the display module goes up with the clock frequency of xck. to minimize data transfer speed of xck cloc k 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 sy stem for data input to minimize the power consumption with data input terminals of each driver lsi being activated only when re levant data input is fed. www.datasheet.co.kr datasheet pdf - http://www..net/
spec no. lcy-w06802 model no. LM057QC1T08 page 14 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 fe d. 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. 4 and table 8. www.datasheet.co.kr datasheet pdf - http://www..net/
