6.1 Circuit Configuration

. Fig. 7 shows the block diagram of the Unit's circuicry.

6.2 Display Face Configuration

The display face electrically consists of two (upper and lower) . display segments so that the unic may offer higher contrast by veducing drive duty ratio. Each display segment (40x 20Qdots) is driven at 1/2OQQduty ratio. et) 6,3) Input Data and Control Signal LESS a : : The LCD driver is 80 bits LSI, consiscing of shift registers, latch circuits and LCD driver circuits. Display data which are externally divided into data for each row (640dots) 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 data of one row (64QOdots) have been inputted, then latched in the form of parallel data for 640 lines of signal electrodes by Latch Signal CP]. Then the corresponding drive signal will be transmitted 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 lst row of scan electrodes, and the contents of the data signals are displayed on the lsc rows of upper and lower half of the display face according to the combinations of voltages applied to the scan and signal electrodes of the LCD, ’ While the lst rows of data are being displayed, the 2nd rows of data are entered. When@4()dots of data have been transferred then bas \\ #: atehed on the!Falling edge of CP; clock, che display face proceeds , oe /.,to the 2nd rowg'-of display, . Such data input will be repeated up to the2QOth row of each dis- . play segment, from upper to lower rows, to complete one frame of . display by time sharing method. Then data input proceeds to the next display face. Scan start-up Signal $ generates scan signal to drive horizontal electrodes. The unit shall be driven at the speed of 50 -GQHz/frame to avoid flickering. . Since DC voltage, if applied to LCD panel, causes chemical reaction which will deteriorate LCD panel, drive waveform shall be inverted at every,display frame to prevent the generation of such DC vol- tage. Control Signal M plays such role.

21-JUN-99 MON 11:52 SHARP ELECTRONICS UK P. 02 . MonkL PAGE LM640328 at -_ SHARP “ “yy Beeause of the characteristics of the CMOS driver LSI; the power we “consumption of the unit goes up as the operating frequency CP? increases. Thus the driver LSI applies the system of transfer- ving 4-bit parallel data through the 4 lines of shift registers to reduce the data transfer speed CP72. Thanks to the LSI, the power consumption of the unit will be minimized. In this circuit configuration, 4-bit display data shall be therefore inputted to data input pins of D 0-3. . . Furthermore the LCD unit adopts bus line system for data input to ie”: minimize the power consumption. :!In this system data input terminal ae /°of each driver LSt ts activated dnly when relevance data input is oe ue fed. . - . Data input for column electrodes of both the upper and the lower display segment and chip select of driver LSI are made as follows: The driver LSI at the left end of the display face is first selec- ted, and the adjacent driver LSI of the right side is selected when 80 dots data(20CP2) is fed. This process is sequentially continued uptil data is fed to the driver LSI at the right end of the display face, This process is simultaneously followed at the column driver LSI's of both the upper and the lower display segments. Thus data iaput for both the upper and the lower display segments must be fed through 4-bit bus line sequentially from the left end of the dis- play face. Since this graphic display unit contains no reflesh RAM, it re— quires data and timing pulse inputs even for static display. : The timing chart of input signals are shown in Fig. 3. w
