SYMBOL VSS Vdd Vo RS FUNCTION Ground terminal of module Supply terminal of module, +5V Power supply for Liquid Crystal Drive Register Select RS = ... Instruction Register RS = 1 ... Data Register 5. R/W Read/Write R/W = 1 ... Read R/W = ... Write 6. 7~14. E DB ~ DB7 Enable Bi-directional Data Bus. Data transfer is performed once, thru DB-DB7, in the case of interface data length is 8-bits; and twice, thru DB4-DB7, in the case of interface data length is 4-bits. Upper four bits first then lower four bits LED or EL lamp power supply terminals LED or EL lamp power supply terminals STANDARD TEMP 0C to +50C -20C to +70C 90% MAX SYMBOL VDD VDD-VO (VLCD) IDD VIL VIH VOL VOH ILED 10L = 1.6 mA 10H = 0.2 mA L+ - L- = 5V VDD = 5V VO = 0V MIN WIDE TEMP -20C to +70C -40C to +85C 90% MAX CONDITION POWER SUPPLY REQUIREMENTS WideTemperature Range Version Standard Super-Twist Display Version When RL=23.5K, VR=10~20K RL=5K, VR=2~5K 15. 16. LAMP- (L-) LAMP+ (L+) *ALL LED BACKLIGHT MODELS HAVE A BUILT-IN LIMITING RESISTOR OPERATING SPECIFICATIONS Operating temperature range Storage temperature range Operating relative humidity PARAMETER Supply Voltage LCD Drive Voltage Normal Temp Model (TN-STN) Wide Temp Model (TN) Wide Temp Model (STN) Supply Current1 Input Voltage2 Output Voltage3 LED Current This circuit shows the typical power supply connection for all dot matrix module. The display Voltage (VLCD) is slightly different for different version (eg. standard, wide temp and supertwist.). Recommend end user to use VARIABLE RESISTOR as shows in the circuit for optimum VLCD (Vdd - Vo ) adjustment to obtain best display contrast and viewing angle. ELECTRICAL CHARACTERISTICS (Ta = +25C) MIN 4.5 4.2 4.4 6.4 0 2.2 2.4 NOTE: * DRIVE VOLTAGE (VLCD) IS IDENTICAL FOR LCD MODULES MANUFACTURES. ACCEPTABLE RESULTS CAN BE OBTAINED BY ADJUSTING VLCD. IF THIS DOES NOT WORK, VIKAY CAN MODIFY DISPLAY TO MEET CUSTOM NEEDS CONSULT FACTORY TYP 5.0 4.5* 4.7 6.8 1.0 40 MAX 5.5 4.8 5.0 7.5 3.0 0.6 VDD 0.4 60 UNIT V V V V mA V V V V mA 1. Applies to DB - DB7, E, RS and R/W 2. Applies to DB - DB7 3. Supply current may slightly exceed MAX. Rating if SAMSUNG controller is used without pull-up resistor for DB - DB7 www.vikay.com Page 2 of 2 |
